TMMH-128-04-L-T

Headers, Male Pins Overview

The TMMH-128-04-L-T is a low-profile header strip manufactured by Samtec Inc. It features a 2.00 mm (0.079 inch) pitch and utilizes a 4-row configuration with 32 total contacts. The connector employs male pin terminals designed for surface mount installation. The housing is constructed from black liquid crystal polymer (LCP), ensuring UL 94 V-0 flammability rating. Contact plating consists of gold over nickel on the mating interface, while the termination side uses tin. The component supports a wide operating temperature range from -55°C to +125°C.

Headers, Male Pins Feature Summary

• Flexible design capability across multiple axes within the Flexyz series architecture
• Low profile form factor optimized for space-constrained board-to-board applications
• Integrated end shroud structure providing terminal protection and alignment

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Embedded systems requiring compact header solutions
• Industrial control modules with limited vertical clearance

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official Samtec documentation to confirm exact termination style and shroud configuration. Ensure compatibility with mating connectors regarding row count and pitch. Confirm RoHS compliance status through current manufacturer certificates before procurement.

Headers, Male Pins Selection Notes

Select this component when a four-row, low-profile header is required for surface mount assembly. Evaluate the 2.00 mm pitch against available routing space. Consider the mechanical stability provided by the shrouded design compared to open-frame alternatives in vibration-prone environments.

Headers, Male Pins Part Context

This part belongs to the TMMH series of flexible through-hole and surface mount headers. The series offers various row counts and contact configurations, allowing designers to customize connector height and density. The TMMH line is characterized by its robust construction and reliable electrical performance in standard industrial conditions.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2.00 mm pitch, 4-row layout, and surface mount termination. Verify that alternative parts maintain identical shroud dimensions and contact material specifications to ensure mechanical fit and electrical continuity.
