M20-9762142

Headers, Male Pins Overview

The Harwin M20-9762142 is a dual in-line (DIL) vertical pin header from the M20 series, designed for board-to-board and wire-to-board connections. It features a 2.54 mm pitch with 21+21 positions arranged in two rows. The connector utilizes through-hole solder termination and includes gold-plated contacts on the mating interface with tin-plated tails for reliable PCB attachment. Rated for 3A current and 750V voltage, it operates within a temperature range of -40°C to 105°C. The housing is constructed from nylon, providing structural integrity without an integrated cover.

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm the 21+21 position count and gold-tin plating combination. Ensure compatibility with mating female connectors from the same M20 series family. Check for RoHS compliance status and lead-free solderability requirements relevant to your manufacturing process before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a vertical, dual-row header with high current capacity is required. The 2.54 mm pitch is industry-standard, ensuring broad availability of mating solutions. Consider the through-hole mounting style for robust mechanical fixation. Evaluate the operating temperature range and voltage rating against the specific environmental conditions of the target application to ensure long-term reliability.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series, a line of 2.54 mm pitch connectors known for their twin beam contact technology. The series offers various configurations including single and double rows, horizontal and vertical orientations, and different plating options. The M20-9762142 specifically represents a high-position-count vertical variant optimized for dense signal or power distribution.

Headers, Male Pins Replacement Considerations

No direct public substitute part numbers are confirmed in the provided data. For equivalent specifications, consider other Harwin M20 series variants with matching 2.54 mm pitch and 21+21 positions. Verify that any alternative maintains the same gold-plated contact finish and through-hole termination method to ensure functional interchangeability.
