MTMM-103-03-G-S-025

Headers, Male Pins Overview

The MTMM-103-03-G-S-025 is a board stacking connector from the Samtec MTMM series, designed for through-hole termination. It features a single row with three male contacts and a 2.00 mm (0.079 in) pitch. The connector utilizes phosphor bronze contacts with selective gold plating on the mating area and matte tin on the tail. It operates within a temperature range of -55°C to +125°C and employs a liquid crystal polymer (LCP) housing rated UL 94 V-0.

Headers, Male Pins Feature Summary

• Variable post height design allows customization of pin length to accommodate specific board stack-up requirements.
• Elastic stacking structure enables flexible alignment and accommodates minor positional deviations during assembly.
• Through-hole solder terminal provides secure mechanical attachment to the printed circuit board.

Headers, Male Pins Applications

• Board-to-board interconnection in compact electronic assemblies
• High-density signal routing in industrial control modules
• Customized header strips for variable thickness stack-ups

Headers, Male Pins Procurement Notes

Verify the exact suffix configuration against the official Samtec datasheet to ensure correct plating specifications and lead style. Confirm that the selected variant matches the required contact count and post height for the target application. Cross-reference the RoHS compliance status and material certifications with the manufacturer's current documentation before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a single-row, three-position through-hole header is required with customizable post heights. Ensure the 2.00 mm pitch aligns with the PCB footprint design. Consider the operating temperature range and UL 94 V-0 flammability rating for environmental suitability. Validate that the male pin configuration matches the mating female connector interface.

Headers, Male Pins Part Context

This part belongs to the MTMM series of modified through-hole headers, characterized by variable post heights and elastic stacking capabilities. The series offers extensive flexibility in pin count and row configuration, supporting up to four rows and varying lengths. It is engineered for applications requiring precise board spacing and reliable electrical connections in space-constrained designs.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2.00 mm pitch, 3-position single-row layout, and through-hole termination type. Verify compatibility of the variable post height feature and contact plating specifications. Consult Samtec's official cross-reference tools or datasheets for approved alternative part numbers within the MTMM family.
