M20-8761542

Headers, Male Pins Overview

The M20-8761542 is a surface mount header connector from the Harwin M20 series, designed for board-to-board or cable-to-board applications. It features a 30-position configuration with two rows and a 2.54 mm (0.100 inch) pitch. The connector utilizes male pins made of brass with gold plating on the mating interface and tin plating on the termination side. Constructed with black polyamide (PA6T) insulation rated UL94 V-0, it supports a maximum current of 3A per contact and a voltage rating of 250V. The operating temperature range spans from -40°C to +105°C.

Headers, Male Pins Feature Summary

Headers, Male Pins Procurement Notes

Verify the specific suffix code against the official Harwin datasheet to confirm exact pin count and packaging configuration. Ensure the ordering part number matches the required quantity per reel or tube specifications. Cross-reference the manufacturing date code to confirm component availability and compliance with current RoHS directives before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a low-profile, dual-row header with push-pull retention is required for SMT assembly. Verify that the mating connector accepts square pins with a compatible engagement length of 5.80mm. Confirm that the PCB layout accommodates the specified insulation height and that the thermal profile supports the PA6T material properties during soldering processes.

Headers, Male Pins Part Context

This part belongs to the M20 series, a family of connectors known for their push-pull locking feature and suitability for harsh environments. The M20 series offers various configurations in single and double rows, catering to diverse spacing and position requirements across industrial, automotive, and telecommunications sectors while maintaining consistent mechanical and electrical standards.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include M20-8761042 (10 positions), M20-8762042 (20 positions), and M20-8763042 (30 positions). These variants share identical mechanical dimensions, locking mechanisms, and electrical ratings, differing only in the total number of contacts available for the specific application design.

Headers, Male Pins FAQ

What is the recommended mating force for the push-pull mechanism?

Official datasheets specify the mechanical engagement characteristics but do not always list a precise numerical mating force value; consult the full mechanical data sheet for detailed force curves if critical.

Is the connector compatible with standard 0.100 inch grid PCB layouts?

Yes, the 2.54 mm pitch is standard for 0.100 inch grid designs, allowing compatibility with most existing board footprints designed for this spacing.
