MTMM-125-11-L-D-430

Headers, Male Pins Overview

The MTMM-125-11-L-D-430 is a variable post height header strip manufactured by Samtec. It features a 2 mm pitch and consists of 50 positions arranged in two rows. The connector utilizes through-hole termination with straight, male pin contacts made of phosphor bronze and gold-plated. The mating post length is specified at 10.922 mm (0.43 in). The housing is constructed from black liquid crystal polymer (LCP) with an unlatched design. It operates within a temperature range of -55 C to +125 C and meets UL 94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Variable post height configuration allows for customized terminal lengths to suit specific application requirements.
• Flex Stack design enables modified body positioning in precise increments to accommodate board stacking variations.

Headers, Male Pins Applications

• Board-to-board interconnections requiring flexible post heights
• High-density electronic assemblies utilizing low-profile headers
• Automotive A-Series product applications

Headers, Male Pins Procurement Notes

Verify the exact suffix code to confirm the specific post height and plating specifications, as these parameters define the functional compatibility. Ensure that the through-hole termination style matches the target PCB layout. Confirm RoHS compliance status and operating temperature ranges against system requirements before finalizing procurement decisions.

Headers, Male Pins Selection Notes

Select this component when variable post height flexibility is required for precise board alignment. The 2 mm pitch supports high-density layouts while maintaining robust current ratings. Verify that the 50-position, dual-row configuration fits the available footprint. Ensure the straight mounting angle aligns with the mechanical constraints of the assembly.

Headers, Male Pins Part Context

This part belongs to the MTMM series of Variable Post Height Header Strips. The series offers extensive customization options for post height and pin count, supporting up to four rows and 200 total pins. It is designed for applications demanding precise mechanical adaptation and reliable electrical connections in compact spaces.

Headers, Male Pins Replacement Considerations

Consult official Samtec documentation for confirmed substitute part numbers. Generic equivalents may not replicate the variable post height or Flex Stack capabilities. Verify dimensional tolerances and contact material specifications before considering alternative components.
