TMMH-104-04-G-DV-A

Headers, Male Pins Overview

The Samtec TMMH-104-04-G-DV-A is a low-profile header strip featuring a 2.00 mm (0.079 inch) pitch and an 8-position, 2-row configuration. Designed for surface-mount installation, it utilizes phosphor bronze contacts with gold plating to ensure reliable signal transmission. The connector incorporates the FleXYZ™ terminal system, allowing for flexible design across multiple axes. It is constructed with a black liquid crystal polymer (LCP) insulator rated UL 94 V-0 for flame resistance. The component operates within a temperature range of -55°C to +125°C and includes end shrouds for alignment protection.

Headers, Male Pins Feature Summary

• FleXYZ™ terminal system provides flexible design capabilities across three axes
• Low-profile construction with integrated end shrouds for board alignment
• Gold-plated phosphor bronze contacts ensure durable electrical performance
• Surface-mount termination supports automated assembly processes

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Embedded systems requiring compact vertical headers
• Industrial control modules with space constraints
• Telecommunications equipment backplanes

Headers, Male Pins Procurement Notes

Verify that the specific suffix 'G' denotes gold contact plating as per Samtec standards, while 'DV' indicates surface mount tails with end shrouds. Confirm RoHS3 compliance status through official documentation before integration. Ensure PCB footprint matches the specified 2.00 mm pitch geometry to prevent misalignment during reflow soldering.

Headers, Male Pins Selection Notes

Select this model when a low-height profile is critical for enclosure clearance. The 2-row arrangement maximizes pin density within a minimal footprint. Verify that the operating current does not exceed ratings defined in the datasheet. Consider the straight mounting angle for standard vertical connections rather than right-angle configurations.

Headers, Male Pins Part Context

This component belongs to the TMMH series of low-profile header strips from Samtec. The series offers various row counts and position options to accommodate diverse connectivity needs. The TMMH line is characterized by its robust mechanical stability and suitability for high-reliability applications in demanding environments.

Headers, Male Pins Replacement Considerations

TMMH-104-04-L-DV-A differs only by tin-plated contacts instead of gold. TMMH-104-04-F-DV-A features a different contact material specification. Direct substitutes must maintain the 2.00 mm pitch, 8-position count, and surface-mount form factor.
