M20-8771942R

Headers, Male Pins Overview

The M20-8771942R is a surface mount pin header from the Harwin M20 series, featuring a single row of 19 positions with a 2.54 mm pitch. Designed for vertical board-to-board or cable connections, it utilizes square male pins made of brass with gold plating on the mating interface and tin on the tail. The connector employs a push-pull locking mechanism and is housed in black polyamide (PA6T) insulation rated UL94 V-0. It supports a maximum current of 3A per contact at 250V, operating within a temperature range of -40°C to 105°C.

Headers, Male Pins Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm reel packaging requirements and orientation. Ensure compatibility with automated pick-and-place equipment specifications. Cross-reference the exact part number with the latest datasheet to confirm current production status and any recent material updates before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a single-row, vertical SMT header with a 2.54 mm pitch is required. Confirm that the 19-position count matches the circuit design. Verify that the push-pull locking feature aligns with assembly constraints. Ensure the operating voltage and current ratings meet the application's electrical demands without exceeding the 3A per contact limit.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, known for high-density rectangular connectors. The M20-877xx series specifically denotes single-row vertical SMT headers. This model provides a robust solution for space-constrained applications requiring reliable signal integrity and mechanical stability through its specialized locking mechanism.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, single-row configuration, and vertical SMT mounting style. Verify that alternative parts offer compatible push-pull locking mechanisms and similar thermal ratings. Check for identical pin counts and contact plating specifications to ensure functional interchangeability.
