M20-9762942

Headers, Male Pins Overview

The M20-9762942 is a vertical pin header connector from the Harwin M20 series, designed for through-hole mounting. It features a 58-position configuration with a 2.54 mm (0.100 in) pitch across two rows. The contacts are constructed from brass and finished with gold plating to ensure reliable signal transmission. The housing is made of black nylon, rated UL94 V-0 for flammability. This component supports mating heights of 5.8 mm, 6.1 mm, and 7.0 mm, providing flexibility for board-to-board or cable applications within standard electronic assemblies.

Headers, Male Pins Feature Summary

• Vertical pin header design suitable for through-hole soldering
• Gold-plated brass contacts for durable electrical connectivity
• UL94 V-0 rated black nylon insulation for fire safety
• Compatible with polarizing keys and bottom entry headers

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable-to-board connections
• General electronic assembly prototyping

Headers, Male Pins Procurement Notes

Verify the specific mating height requirement (5.8 mm, 6.1 mm, or 7.0 mm) against your PCB stack-up before ordering, as this variant supports multiple options. Confirm compatibility with M20-997 bottom entry pin headers if using a dual-sided assembly. Ensure polarizing key requirements are met by checking for the M20-003 accessory if mechanical alignment is critical for your design.

Headers, Male Pins Selection Notes

Select this model when a high-density 58-position connection is required in a vertical form factor. The gold plating makes it suitable for applications where corrosion resistance and low contact resistance are prioritized over cost. Consider the available tail offset dimensions and mating heights to ensure proper clearance and mechanical fit within the enclosure constraints.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series, a widely used line of rectangular connectors known for their versatility and reliability. The M20 series offers various configurations including headers, sockets, and wire housings with 2.54 mm pitch. The M20-9762942 specifically addresses the need for high-pin-count vertical headers in space-constrained environments.

Headers, Male Pins Replacement Considerations

No direct public substitute part numbers are confirmed for this specific 58-position configuration. Evaluate other M20 series headers with matching pin counts and pitch, ensuring identical mating height and contact plating specifications to maintain mechanical and electrical compatibility.
