- For a board-to-board link, what PCB layout constraints should I check before using TMM-136-01-FM-S-RA-007?
- TMM-136-01-FM-S-RA-007 is a right-angle, through-hole header with 2.00 mm pitch, so the main checks are hole size, pad geometry, annular ring, connector keepout, and the mating board envelope. The 35 loaded positions and right-angle body also mean the adjacent component clearance and board edge distance should be verified early, especially if the mating connector is on a compact daughtercard or an enclosure-limited assembly.
- Can TMM-136-01-FM-S-RA-007 be used in a cable-to-board design, or is it better suited to board-to-board?
- TMM-136-01-FM-S-RA-007 is listed for board-to-board or cable use, but the practical fit depends on how the cable is terminated and strain-relieved. For repeated mating or field handling, the push-pull fastening style and unshrouded header geometry should be evaluated against connector retention, operator access, and accidental disconnect risk. If the cable assembly needs keyed alignment or extra mechanical protection, another interconnect style may be easier to control.
- What mating connector characteristics should I match when replacing an existing 2.00 mm header with TMM-136-01-FM-S-RA-007?
- When replacing with TMM-136-01-FM-S-RA-007, the critical checks are pitch, row count, loaded position count, right-angle orientation, contact gender, and the mating stack height implied by the system. Even when the pitch matches, differences in contact length, board-side protrusion, and housing geometry can change insertion depth and retention. A replacement should be verified against the original footprint and the mating receptacle drawings rather than only the nominal 2.00 mm spacing.
- Is TMM-136-01-FM-S-RA-007 appropriate for designs that need high vibration resistance?
- TMM-136-01-FM-S-RA-007 has a push-pull fastening style, which can help with retention in controlled assemblies, but vibration performance still depends on the full mechanical stack. In industrial equipment, you should check connector anchoring on the PCB, board support, cable routing, and whether the mating side maintains stable normal force over life. If the product will see sustained shock or vibration, the system may need additional retention features beyond the connector itself.
- Can TMM-136-01-FM-S-RA-007 handle power distribution as well as signals?
- TMM-136-01-FM-S-RA-007 is rated at 3.2 A per contact, so it can support moderate power delivery if the pin assignment, copper width, thermal rise, and simultaneous current sharing are designed carefully. For power use, derating is usually driven by ambient temperature, number of loaded positions, and how many contacts carry current at once. If several adjacent pins are used for power, trace heating and connector temperature rise should be checked at the system level.
- What should I consider about the gold mating finish on TMM-136-01-FM-S-RA-007 for low-level signals?
- TMM-136-01-FM-S-RA-007 uses gold on the mating interface, which helps with contact consistency for low-level signals and repeated mating. The practical concern is not just the finish itself, but also the environment, mating cycle count, and whether the mating partner uses a compatible contact system. For very low-voltage or low-current signals, keeping the interface clean and maintaining stable normal force matters as much as the plating choice.
- How does TMM-136-01-FM-S-RA-007 behave in high-temperature industrial equipment?
- TMM-136-01-FM-S-RA-007 is specified for -55 C to 125 C, so it can fit many industrial temperature envelopes. The limiting factors in long-term use are often not the stated range alone, but PCB laminate selection, solder joint reliability, nearby heat sources, and the mating connector's thermal expansion behavior. If the assembly sees repeated thermal cycling, the through-hole solder joints and board support should be reviewed for fatigue risk.
- Is TMM-136-01-FM-S-RA-007 a good replacement for another Samtec TMM series header?
- TMM-136-01-FM-S-RA-007 can be a practical replacement within the TMM family if the pitch, orientation, loaded position count, and mating envelope match the existing design. The suffix details matter because small differences can affect footprint compatibility, contact engagement, and cable or board clearance. It is better to compare the exact mechanical drawing and pin population than to assume all TMM variants are interchangeable.
- What are the main risks when using TMM-136-01-FM-S-RA-007 on a compact multilayer PCB?
- On a compact board, TMM-136-01-FM-S-RA-007 can create clearance challenges at the board edge and on the mating side because the right-angle form extends horizontally from the PCB. The 35 loaded positions also mean routing density can become tight near the connector. Designers should reserve space for solder tails, assembly tooling, and mating access, then verify that vias and copper pours do not interfere with the through-hole pins or the insertion path.
- How do I know whether TMM-136-01-FM-S-RA-007 is suitable for a design that may be serviced in the field?
- TMM-136-01-FM-S-RA-007 can work in serviceable equipment if the push-pull retention, unshrouded profile, and contact access align with the maintenance procedure. Field service usually exposes connectors to mixed-quality handling, so mating force, board retention, and the likelihood of reverse insertion or misalignment should be reviewed. If the system must tolerate frequent reconnects by non-specialists, it is worth checking whether a keyed or shrouded alternative would reduce assembly errors.
- What should I verify before moving from a vertical header to TMM-136-01-FM-S-RA-007 right-angle mounting?
- Switching to TMM-136-01-FM-S-RA-007 changes the mechanical envelope, cable exit direction, and board keepout. You should verify that the mating partner still clears nearby components, that the board edge can accommodate the connector body, and that the solder joints can tolerate the bending loads introduced by the right-angle format. In practice, the electrical pinout may stay the same while the mechanical integration changes substantially.
- Are there any reasons not to use TMM-136-01-FM-S-RA-007 in a harsh-environment design?
- TMM-136-01-FM-S-RA-007 can be used in many demanding applications, but the part is unshrouded and does not list ingress protection, so exposure to dust, condensation, or handling contamination must be managed by the enclosure and system design. If the application involves splash, corrosive atmospheres, or repeated uncapped exposure, the connector interface may need extra protection or a different interconnect architecture. The decision usually comes down to whether the surrounding product can keep the mating area clean and mechanically stable over time.
