Frequently Asked Questions

Can I use MTSW-113-11-L-D-740 as a board-to-board connector in a compact 2.54 mm stack-up, and what mechanical constraints should I check first?
MTSW-113-11-L-D-740 is a Samtec Flex Stack through-hole header for 2.54 mm board-to-board or cable interfaces, so the first checks are mating height, board-to-board clearance, and mechanical keepout around the 26-position, 2-row footprint. Because the part is unshrouded and uses a push-pull style mating interface, you should verify alignment tolerance in the PCB stack and confirm that the mating connector or cable assembly can fully engage without side loading.
Is MTSW-113-11-L-D-740 suitable for replacing a generic 0.100 inch dual-row header, and what should I verify before swapping it into an existing design?
MTSW-113-11-L-D-740 can replace many standard 2.54 mm dual-row headers, but pin length, post length, and mating geometry should be checked against the original part. The 0.740 inch mating contact length and 0.090 inch post length affect both insertion depth and solder side clearance, so the replacement is only straightforward when the existing receptacle or harness matches those dimensions and the board hole pattern is compatible.
What signal and power limits should I consider when using MTSW-113-11-L-D-740 for a mixed-signal or low-power control interface?
MTSW-113-11-L-D-740 is rated for 3 A per contact, so it is better suited to control, data, and modest power distribution than to high-current rails. For mixed-signal use, route power and returns with attention to contact loading, adjacent-circuit noise coupling, and return-path continuity, especially because the connector is unshrouded and does not provide additional isolation between neighboring pins.
Can MTSW-113-11-L-D-740 be used in a cable-to-board connection, or is it better suited to board-to-board stacking?
MTSW-113-11-L-D-740 supports both board-to-board and cable-style use at the interface level, but practical cable use depends on the mating assembly and strain relief. For cable applications, make sure the harness or mating connector maintains stable alignment and does not place bending load on the through-hole solder joints, since the header itself is not a cable-retention system.
What are the implications of the gold mating finish and tin post finish on MTSW-113-11-L-D-740 for long-term reliability?
MTSW-113-11-L-D-740 uses gold on the mating contacts and tin on the post side, which is a common combination for low-resistance mating performance and solderability. In long-life equipment, the actual reliability depends on mating cycle count, contact wipe, contamination exposure, and whether the connector is operated within its rated current and temperature range. If the application involves frequent reconnects or harsh contamination, validate contact resistance drift under real environmental conditions.
Is MTSW-113-11-L-D-740 appropriate for industrial temperature ranges and extended field operation?
MTSW-113-11-L-D-740 is specified for -55°C to 125°C, which supports many industrial and embedded systems. For extended field use, the remaining questions are board thermal profile, vibration, solder joint fatigue, and connector retention under repeated thermal cycling. The through-hole termination helps mechanical robustness, but the full assembly still needs validation under the system’s actual thermal and shock environment.
How do I choose a replacement if I need the same footprint as MTSW-113-11-L-D-740 but want different mating height or retention behavior?
With MTSW-113-11-L-D-740, the critical variables are pitch, row spacing, loaded positions, contact length, and stack height. If you need a different mating height or retention feel, compare the MTSW series variants with the same 26-position, 2-row geometry and check whether the alternate part changes the exposed post length or engagement depth. Small changes there can affect enclosure clearance, connector wear, and how much axial force is transferred into the PCB.
What should I watch for if I’m using MTSW-113-11-L-D-740 on a board that may experience vibration or handling stress?
MTSW-113-11-L-D-740 is a through-hole header, so the soldered pins generally provide better mechanical anchoring than surface-mount options. Even so, vibration performance depends on the mating connector fit, board support, and whether the assembly sees repeated cable tugging or board flex. For stressed environments, design in board standoffs, minimize leverage on the connector, and confirm that the mating part maintains stable contact normal force across the operating range.
Is MTSW-113-11-L-D-740 a good choice when I need a compact 26-position connector but cannot tolerate shrouded housing height?
MTSW-113-11-L-D-740 is unshrouded, which keeps the profile simpler and can help in tight layouts where a shroud would interfere with nearby parts. The tradeoff is reduced guided insertion, so the mating side must be well-controlled mechanically. If the assembly will be hand-mated or field-serviced, consider whether the exposed pins and alignment requirements are acceptable for the enclosure and service process.
What are the main trade-offs between MTSW-113-11-L-D-740 and a lower-cost generic header for production hardware?
Compared with many generic headers, MTSW-113-11-L-D-740 offers a defined Samtec construction, gold-plated mating surfaces, a specified 3 A current rating, and a broad operating temperature range. The practical trade-off is usually cost versus tighter control over contact performance, dimensional consistency, and long-term mating behavior. For production hardware, that difference matters most when the connector sits on a critical interconnect path or is expected to survive repeated service cycles.
