HMTSW-101-24-SM-S-240

Headers, Male Pins Overview

The HMTSW-101-24-SM-S-240 is a single-row, one-position vertical PCB header from the Samtec Flex Stack series. It features a 2.54 mm (0.100 in) pin pitch and through-hole solder termination. The connector utilizes phosphor bronze contacts with 30 µin gold plating on the mating interface and tin plating on the tail. Designed for high-temperature applications, it operates between -55°C and +125°C. The insulator is made of natural liquid crystal polymer (LCP) rated UL 94 V-0. Key dimensions include a 6.10 mm (0.240 in) mating contact length, a 3.56 mm (0.140 in) post length, and a total contact length of 12.19 mm (0.480 in).

Headers, Male Pins Feature Summary

• Modified .025" square post design allows for custom post heights to accommodate variable board stack-up requirements.
• High-temperature construction using LCP insulation supports reliable performance in elevated thermal environments.
• Flexible stacking capability enables precise alignment and connection across multiple circuit board layers.

Headers, Male Pins Applications

• Board-to-board interconnections requiring specific height tolerances
• High-temperature PCB assembly processes
• Multi-layer circuit board stacking

Headers, Male Pins Procurement Notes

Verify the exact suffix code 'SM' against the manufacturer datasheet to confirm the specific modified post height configuration. Ensure the required operating temperature range aligns with the component's -55°C to +125°C specification. Confirm that the through-hole termination method matches the target PCB fabrication capabilities. Check RoHS compliance status if restricted substances are a project constraint.

Headers, Male Pins Selection Notes

Select this component when a standard header does not meet specific mechanical height constraints due to its modified post flexibility. Consider the 3A current rating and 2.54 mm pitch for signal or low-power power distribution. Evaluate the LCP material properties for thermal stability during reflow soldering. Compare against other HMTSW variants if different pin counts or row configurations are needed.

Headers, Male Pins Part Context

This part belongs to the HMTSW series, which represents modified .100" pitch terminal strips designed for high-temperature applications. The series offers extensive customization in post height to solve complex stacking challenges. It complements the broader MTSW family by providing enhanced thermal resilience and flexible mechanical solutions for demanding electronic assemblies.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include HMTSW-101-24-SM-S-230, which shares identical electrical and mechanical specifications but features a slightly different post height configuration. Verify dimensional compatibility before swapping to ensure proper mating with existing connectors.
