M20-9763946

Headers, Male Pins Overview

The M20-9763946 is a Harwin M20 series single-row pin header connector with a 2.54 mm pitch and 78 positions. It features vertical through-hole mounting, tin-plated brass contacts, and a black nylon housing. Rated for 3 A current and 750 V voltage, it operates between -40°C and +105°C. The connector has a 3 mm tail pin length and a 6.1 mated pin length, designed for board-to-board or wire-to-board applications without a cover.

Headers, Male Pins Feature Summary

• Vertical single-row configuration for standard PCB insertion
• Tin-plated brass contacts ensure reliable conductivity
• Nylon housing provides structural stability and insulation

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Wire-to-board signal routing
• Industrial control panel assembly

Headers, Male Pins Procurement Notes

Verify the specific 78-position variant against project requirements. Confirm RoHS compliance status via official datasheets. Check for end-of-life notices as some M20 variants face obsolescence. Ensure compatibility with mating sockets regarding pin height and pitch tolerances before finalizing supply chain agreements.

Headers, Male Pins Selection Notes

Select this component when high channel density is required in a single row. The 2.54 mm pitch suits general-purpose digital signals. Verify that the 3 A rating meets circuit load demands. Consider the vertical orientation for space-constrained layouts where side access is unavailable.

Headers, Male Pins Part Context

Part of the Harwin M20 family, known for versatile 2.54 mm spacing solutions. This model represents a high-count single-row option within the series, complementing lower-pin-count headers and dual-row alternatives for diverse connectivity needs.

Headers, Male Pins Replacement Considerations

M20-9763846 (76 positions) and M20-9764046 (80 positions) are adjacent pin counts. Cross-reference mechanical dimensions and electrical ratings to ensure functional equivalence if substituting.
