MTMM-118-15-T-D-680

Headers, Male Pins Overview

The MTMM-118-15-T-D-680 is a variable post height header strip manufactured by Samtec Inc. It features a 2.00 mm pitch and consists of 36 positions arranged in two rows. Designed for through-hole termination, the connector utilizes tin-plated phosphor bronze contacts with a matte finish on both the contact and tail areas. The housing is constructed from black liquid crystal polymer (LCP) rated UL 94 V-0. The mating post length is specified at 17.272 mm (0.68 in), while the insulator height measures 1.50 mm. The component operates within a temperature range of -55°C to +125°C.

Headers, Male Pins Feature Summary

• Variable post height design allows for customized stacking configurations up to 200 pins across four rows.
• Through-hole termination ensures secure board attachment with solder pin end types.
• Unlatched locking mechanism provides flexible connection without mechanical retention latches.

Headers, Male Pins Applications

• Board-to-board interconnections requiring specific vertical spacing
• High-density electronic assemblies utilizing 2.00 mm pitch headers
• Custom stacking solutions for multi-layer circuit boards

Headers, Male Pins Procurement Notes

Verify the suffix code T indicates matte tin plating on contacts and tails, distinct from gold or mixed plating options. Confirm the D designation specifies a dual-row configuration with 36 total positions. Ensure the 680 suffix corresponds to the required 17.272 mm mating post length for your application stack-up. Cross-reference the LCP insulation material and UL 94 V-0 rating against environmental requirements.

Headers, Male Pins Selection Notes

Select this model when a fixed-height header does not meet the specific board-to-board distance requirements. The variable post feature accommodates different PCB thicknesses or spacer heights. Verify that the 2.00 mm pitch aligns with the mating connector footprint. Consider the tin plating suitability for the operating environment compared to gold alternatives if corrosion resistance is critical.

Headers, Male Pins Part Context

This component belongs to the MTMM series of Variable Post Height Header Strips. The series offers customizable lengths and row configurations to suit diverse assembly needs. The MTMM-118-15-T-D-680 specifically addresses applications needing a 36-position dual-row interface with precise vertical alignment capabilities provided by the adjustable post design.

Headers, Male Pins Replacement Considerations

Substitutes must match the 2.00 mm pitch, 36-position dual-row layout, and through-hole termination style. Verify that any alternative part supports the same 17.272 mm mating post length or adjust the mechanical design accordingly. Ensure the replacement maintains the LCP insulation material and compatible operating temperature range.
