- Can the Glenair 806-022-Z116-31S1TE be used in applications requiring continuous operation above 150°C, and what design considerations apply?
- The 806-022-Z116-31S1TE is rated for -65°C to 200°C operation, making it suitable for sustained high-temperature environments. However, at temperatures above 150°C, solder joint reliability becomes the limiting factor rather than the connector itself. Verify that your PCB substrate and solder alloy specifications match the connector's thermal profile; lead-free solders may require process adjustment. Additionally, thermal cycling stress concentrates at the solder interface, so design for mechanical strain relief in high-vibration aerospace applications. Gold-plated mating contacts maintain low contact resistance across this range, but ensure backshell thermal management to prevent adjacent component degradation.
- What are the practical differences between the 806-022-Z116-31S1TE and comparable 31-position receptacles from other manufacturers when replacing legacy connectors?
- The 806-022-Z116-31S1TE (Mighty Mouse 806 series) uses a 16-31 shell size with threaded coupling, which differs from standard mil-spec alternatives like the Amphenol PT or ITT Cannon equivalents that may employ bayonet or push-pull fastening. Migration requires validation of panel cut-outs, depth clearance, and coupling torque specifications. The 806-022-Z116-31S1TE's aluminum shell with passivation finish offers corrosion resistance but is lighter than stainless alternatives; in high-vibration or marine environments, additional mechanical retention or potting may be necessary. Current rating (5A per contact) and voltage (1800VAC) typically align with legacy designs, but verify that the 50µin gold plating thickness meets your contact life and wear requirements.
- How does the unshielded configuration of the 806-022-Z116-31S1TE affect EMI in mixed-signal aerospace systems?
- The 806-022-Z116-31S1TE is unshielded, making it unsuitable for applications combining high-frequency analog signals and digital logic without additional mitigation. In aerospace mixed-signal designs, implement individual twisted-pair shielding for sensitive analog lines within the connector backshell, or specify a shielded variant if available. Signal-to-ground spacing within the 31-position layout must follow design guidelines (typically 1/10 wavelength at the highest frequency of interest). For applications below approximately 1 MHz with adequate trace routing discipline, the unshielded design often suffices; above this threshold, isolation techniques or a shielded alternative become necessary.
- What are the soldering challenges specific to the 806-022-Z116-31S1TE's 31-position through-hole design in high-reliability applications?
- The 806-022-Z116-31S1TE uses solder termination on a through-hole flange mount, presenting several reliability concerns in high-vibration or temperature-cycling environments. With 31 solder joints, thermal stress is distributed across a larger area, increasing the likelihood of cold-solder or micro-crack initiation. Use controlled-atmosphere reflow or selective wave soldering to ensure consistent wetting; hand soldering is not recommended for production. The aluminum flange can absorb thermal energy unpredictably, potentially creating reflow process hotspots. Design the PCB ground plane to provide thermal mass near the connector footprint, and include test coupons to validate joint quality via cross-section analysis. Post-soldering X-ray inspection is advisable for aerospace qualification.
- Can the 806-022-Z116-31S1TE replace military-grade sealed connectors in pressurized avionics cabins?
- The 806-022-Z116-31S1TE is rated as environment-resistant but is not a hermetic or sealed connector. It is unsuitable for pressurized environments or applications requiring absolute gas-tight integrity. If your design previously used a sealed mil-spec connector (such as an MIL-DTL-38999 variant), the 806-022-Z116-31S1TE cannot be a direct drop-in replacement without redesign. Instead, specify a Glenair sealed variant (such as models in the 801 or 800 series with pressure-seal backshells) or evaluate alternative manufacturers offering equivalent sealed 31-position receptacles. Failure to migrate to a sealed design risks outgassing, moisture ingress, and contact corrosion in cabin pressurization cycles.
- What is the maximum panel thickness and mounting depth for the 806-022-Z116-31S1TE in space-constrained avionics bays?
- The 806-022-Z116-31S1TE uses a flange-mount, through-hole design but the exact mounting depth and maximum panel thickness are not specified in the base datasheet. Contact Glenair technical support with your specific panel geometry to confirm fit. Typical Mighty Mouse 806 series receptacles accommodate panels up to 0.188 inches (4.8 mm) thick; however, verify this for the 31-position insert size. The threaded coupling adds approximately 0.5 to 0.75 inches of connector depth beyond the flange, so design the backshell cavity with adequate clearance. In retrofit scenarios, measure existing connector clearances before committing to the 806-022-Z116-31S1TE.
- How do the 50µin gold-plated contacts of the 806-022-Z116-31S1TE perform over repeated mating cycles, and when should re-plating be considered?
- The 806-022-Z116-31S1TE's 50µin (1.27µm) gold mating finish is within typical commercial aerospace specifications and provides approximately 50 to 100 mating cycles before visible wear in low-current applications (under 1A per contact). At the connector's rated 5A per contact, contact wear accelerates due to frictional heating and micro-arcing on each insertion. For field-replaceable unit (FRU) connectors subject to frequent disconnect-reconnect cycles, design spares with virgin plating or establish a re-plating schedule. Inspect contacts visually every 30 to 50 cycles; once plating wear exposes copper substrate, migration risk increases and re-plating or connector replacement becomes necessary to maintain contact resistance below 50mΩ.
- Is the 806-022-Z116-31S1TE compatible with automated insertion equipment in high-volume manufacturing?
- The 806-022-Z116-31S1TE's solder termination and through-hole flange mount are compatible with standard PCB assembly processes but require specific fixture design. The 31-position pin layout and flange geometry necessitate custom solder pallets and tooling to avoid contact misalignment during placement and reflow. The threaded backshell adds complexity to inline insertion; confirm that your assembly partner's equipment can handle the connector's overall length and mass without fixture interference. For high-volume builds (>1000 units), coordinate with Glenair or an authorized distributor to validate tooling specifications and negotiate lead times on custom fixtures.
- What preventive maintenance or field inspection procedures apply to 806-022-Z116-31S1TE connectors in long-term aerospace storage?
- The 806-022-Z116-31S1TE's aluminum shell with passivated finish resists corrosion but can develop white oxide deposits under high-humidity storage. Periodically inspect stored connectors (quarterly or semi-annually) for visible corrosion, contact tarnishing, or contamination. Store units in sealed containers with desiccant packs in a controlled environment (relative humidity <40%). Before field installation after extended storage, perform a visual inspection and continuity check across all 31 contacts using a multimeter; do not apply full voltage until connectivity is verified. If corrosion is detected on shell or contacts, clean with isopropyl alcohol and soft brush, allow to dry completely, and re-inspect before use.
- Does the 806-022-Z116-31S1TE require backshell grounding or additional EMI filtering for 1800VAC power distribution circuits?
- The 806-022-Z116-31S1TE is unshielded and carries a 1800VAC rating, so ground straps or grounding clips are not built-in but are strongly recommended in power distribution applications. Route a ground conductor from the aluminum backshell to the panel ground plane using a 10 AWG or larger wire to establish a low-impedance return path and reduce radiated EMI. For circuits switching at frequencies above 100 kHz or in high-EMI environments, add ferrite clamps around the backshell connector area or specify EMI filtering on the backshell assembly. Consult your system-level EMI analysis to determine filtering requirements; the 1800VAC rating alone does not guarantee compliance with DO-160G or MIL-STD-461 EMI/RFI limits without additional shielding or filtering design.
- Can the 806-022-Z116-31S1TE withstand thermal shock cycles between -65°C and +200°C without connector or solder joint failure?
- The 806-022-Z116-31S1TE's -65°C to +200°C operating range supports extreme thermal transients, but connector reliability depends on PCB material selection and solder joint design. Aluminum shell and copper-alloy contacts have different thermal expansion coefficients, which may induce micro-stress during rapid transitions. FR-4 PCBs expand differently than ceramic substrates, potentially compromising solder joint integrity over 50+ thermal cycles. For high-reliability applications (military or space), use polyimide or ceramic substrates and lead-free solder formulations with higher reflow temperatures to improve joint strength. Perform thermal cycling testing (per MIL-STD-810H or equivalent) on prototype assemblies to validate design margins before full production.
- How should the 806-022-Z116-31S1TE be integrated with backshell variants (strain relief, potting, etc.) in vibration-prone environments?
- The 806-022-Z116-31S1TE accepts various backshell configurations from Glenair, including cable strain relief, potting enclosures, and filtered backshells. In high-vibration environments (aerospace, defense), a backshell with integral strain relief and potting is essential to reduce stress on solder joints and prevent intermittent connections. Potting compounds must be thermally matched to the connector shell and PCB to minimize differential expansion. Consult Glenair's backshell compatibility guide for the 806-022-Z116-31S1TE to select appropriate part numbers and curing processes. Verify that potting viscosity does not migrate into contact cavities, which can increase contact resistance or cause insertion force issues.
- What are the contact resistance and leakage current specifications for the 806-022-Z116-31S1TE at full voltage and temperature extremes?
- The 806-022-Z116-31S1TE's gold-plated contacts and 5A current rating imply contact resistance below 50mΩ under normal conditions; however, detailed resistance curves across the -65°C to +200°C range are not provided in the base datasheet. At +200°C, contact resistance may increase 10–20% due to thermal effects on plating and substrate. Leakage current at 1800VAC is typically <1mA for unshielded connectors but depends on humidity and surface contamination. Request contact resistance and leakage test data from Glenair for your specific application, especially if design margins are tight or if the circuit operates at full voltage continuously. Include margin analysis in your qualification plan.
- Is the 806-022-Z116-31S1TE suitable for medical device applications, or are there regulatory restrictions?
- The 806-022-Z116-31S1TE is rated for aerospace applications and carries EAR99 export control and REACH "unaffected" status but is not specifically qualified for medical device use. Medical device regulations (FDA 21 CFR Part 11, ISO 13485) require documented material traceability, biocompatibility testing, and process validation that are not standard for aerospace connectors. If medical use is required, contact Glenair to determine whether a medical-grade variant is available or whether the standard 806-022-Z116-31S1TE can be qualified under your device's design control and risk management procedures. Material composition (aluminum shell, copper-alloy contacts) must be evaluated for biocompatibility if fluid contact is possible.
