M20-9763542

Headers, Male Pins Overview

The M20-9763542 is a vertical pin header from the Harwin M20 series, designed for board-to-board or wire-to-board connections. It features a 2.54mm pitch and comprises 70 positions arranged in two rows (35+35). The connector utilizes square brass contacts with gold plating on the mating interface and tin plating on the tail. Constructed with black polyamide (PA6T) insulation rated UL94 V-0, it supports a rated voltage of 250V and a current of 3A per contact. Operating temperatures range from -40°C to 105°C. The component employs through-hole termination and offers selectable stacking heights of 11.53mm, 12.23mm, 12.63mm, and 18.13mm.

Headers, Male Pins Procurement Notes

Verify the specific stacking height variant required for your assembly, as the M20-9763542 designation covers multiple height options. Confirm that the gold-plated contact finish aligns with your signal integrity specifications. Ensure compatibility with standard 2.54mm pitch mating sockets. Check for RoHS compliance status if restricted substances are a concern in your manufacturing process.

Headers, Male Pins Selection Notes

Select this component when a vertical, dual-row header with high contact density is necessary. The 2.54mm pitch allows for broad compatibility with standard PCB footprints. Consider the available stacking heights to determine the appropriate mechanical profile for your enclosure constraints. The gold contact finish is suitable for low-level signal applications where oxidation resistance is critical.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used line of rectangular connectors known for their reliability and versatility. The M20 series offers various configurations including single and double rows, different mounting styles, and contact finishes. The M20-9763542 specifically addresses needs for vertical, high-pin-count interconnections in compact spaces.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M20 series headers with identical 70-position, 2.54mm pitch, and vertical orientation. Verify that any replacement matches the required stacking height and contact plating specifications. Cross-brand replacements must be evaluated for mechanical fit and electrical rating equivalence.
