Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

How do I verify whether 887-074-521-207 will accept my PCB card edge thickness without intermittent contact issues?
For 887-074-521-207, the specified card thickness range is 0.054" to 0.070" (1.37 mm to 1.78 mm). If your board is outside that range, insertion force, contact wipe, and retention can drift from the intended behavior. In practice, confirm the finished board thickness after solder mask and plating, and check whether the edge bevel and gold finish on the PCB match the connector’s contact geometry.
Can 887-074-521-207 be used in a design that needs 3.3 V or 5 V logic isolation between boards?
887-074-521-207 is a passive card edge connector, so it does not provide voltage translation or isolation by itself. It can carry 3.3 V, 5 V, and other board-level signals as long as the system meets the connector’s spacing, creepage, clearance, and current requirements. If your architecture needs isolation, level shifting, or hot-swap protection, those functions need to be added elsewhere in the design.
What should I check when replacing an older dual-edge connector with 887-074-521-207?
When evaluating 887-074-521-207 as a replacement, verify the 74-position, dual-row, 0.156" pitch layout, mounting style, and front-panel or flange constraints. A direct swap also depends on board edge geometry, keepout, insertion depth, and solder footprint. Even if the pin count matches, a different contact wipe length or housing offset can change mating reliability and mechanical clearance.
Is 887-074-521-207 suitable for industrial equipment exposed to temperature cycling and vibration?
887-074-521-207 is rated for -40°C to 125°C, which supports many industrial environments, but long-term reliability also depends on the mechanical load on the PCB, enclosure support, and vibration profile. The through-hole solder termination and threaded insert flange can help with retention, yet the final design should still prevent board flex at the connector and limit side loading during mating and service.
How should I design the PCB footprint for 887-074-521-207 to avoid assembly or mating problems?
For 887-074-521-207, the footprint should preserve the 0.156" pitch, dual-row alignment, and through-hole solder access while respecting the connector’s flush-mount and top-opening flange geometry. The board edge, hole tolerances, and silkscreen should not interfere with the card entry path. It is also common to confirm the final assembly stack-up with a mechanical drawing, since small shifts in board position can affect insertion and contact engagement.
Does 887-074-521-207 need any special attention for gold contact reliability over long service life?
887-074-521-207 uses gold contact finish with 10.0 µin (0.25 µm) thickness on copper alloy contacts, which is a common choice for lower contact resistance and better corrosion resistance. For long service life, the main concerns are fretting from vibration, contamination on the card edge, and insufficient wipe from an out-of-spec PCB thickness. Keeping the mating surfaces clean and within the specified thickness range helps preserve stable electrical performance.
Can 887-074-521-207 be used for high-speed signals, or should I choose a different connector type?
887-074-521-207 can carry digital signals, but whether it is appropriate for high-speed use depends on the signal integrity budget, pin assignment, return path planning, and the interconnect length. A card edge connector introduces discontinuities and pin-to-pin variation that may be acceptable for moderate-speed buses but not for tighter impedance or eye-diagram requirements. If the design is sensitive to crosstalk or controlled impedance, you should model the interconnect rather than assuming the connector is transparent.
Are there practical reasons to choose 887-074-521-207 over a keyed board-to-board connector?
887-074-521-207 is a card edge connector, so it can be a good fit when the plug-in card itself must be the removable element and when the system already uses edge-finger routing. Compared with a keyed board-to-board connector, it usually offers a different mechanical profile and a more direct edge-connection approach, but it may require stricter control of PCB edge finish and insertion guidance. The better choice depends on the service model, mating cycle count, and available chassis depth.
What manufacturing tolerances matter most when building a card for 887-074-521-207?
For 887-074-521-207, the most relevant tolerances are finished board thickness, edge plating consistency, edge bevel quality, and the positional accuracy of the contact fingers relative to the 74-position dual-row layout. If those features drift, the connector may still mate but with uneven wipe or localized wear. In production, it is worth checking the actual board fab capability against the connector’s specified 1.37 mm to 1.78 mm thickness window.
Is 887-074-521-207 appropriate for designs that must survive storage, shipping, or humid environments?
887-074-521-207 is RoHS3 compliant, REACH unaffected, and has MSL 1 classification, so it does not impose special moisture handling constraints at the package level. For the final assembly, humid storage and shipping concerns are usually managed through enclosure design, contamination control, and contact protection rather than the connector alone. If the application sees condensation, the real question is whether the exposed edge contacts and board finish remain stable under that exposure profile.
