M20-9961946

Headers, Male Pins Overview

The M20-9961946 is a Harwin Inc. pin header connector from the M20 series, designed for board-to-board or cable applications. It features a single row with 19 positions and a 2.54mm (0.100 inch) mating pitch. The connector utilizes square male pins made of brass with tin plating on both mating and tail sections. It supports through-hole vertical mounting and employs a push-pull fastening type. The housing is constructed from black polyamide (PA6T) nylon, rated UL94 V-0, with an operating temperature range of -40°C to 105°C.

Headers, Male Pins Feature Summary

• Square male pin configuration with tin-plated contacts for reliable signal transmission
• Push-pull fastening mechanism ensures secure mating without additional screws
• Cuttable design allows for flexible position selection during assembly
• UL94 V-0 rated polyamide insulation provides flame resistance and thermal stability

Headers, Male Pins Applications

• Board-to-board interconnections in compact electronic modules
• Cable-to-board connections requiring vertical orientation
• Industrial control systems operating within specified temperature ranges
• Consumer electronics utilizing standard 2.54mm spacing layouts

Headers, Male Pins Procurement Notes

Verify the specific contact plating and housing material against official datasheets before procurement. Confirm that the push-pull fastening requirement aligns with system mechanical constraints. Ensure compatibility with mating connectors regarding pin length and insulation height. Check for RoHS compliance status if required by project specifications. Validate that the through-hole mounting style matches the PCB fabrication capabilities.

Headers, Male Pins Selection Notes

Select this component when a single-row, 19-position vertical header is required. The 2.54mm pitch suits general-purpose digital and low-power analog signals. Consider the tin plating for cost-effective solderability compared to gold options. The cuttable feature offers inventory flexibility for varying circuit densities. Ensure the 3A current rating per contact meets the electrical load requirements of the application.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a family of high-density connectors known for robust mechanical performance. The M20-996 prefix indicates a single-row, right-angle or vertical header variant depending on the specific suffix code. This series is widely used in automotive, industrial, and telecommunications equipment where reliable interconnection is critical.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other Harwin M20 series headers with identical pitch and row count but different pin counts or plating. Verify mechanical dimensions and fastening type before substitution. Generic equivalents must match the 2.54mm pitch and square pin profile to ensure proper mating.
