M20-9971046

Headers, Male Pins Overview

The M20-9971046 is a 20-position, dual-row male pin header from the Harwin M20 series. It features a 2.54 mm (0.100 inch) pitch and is designed for vertical through-hole mounting on printed circuit boards. The connector utilizes phosphor bronze contacts with tin over nickel plating to ensure reliable signal transmission. Rated for 3A maximum current and 1000V dielectric strength, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black UL94 V-0 rated polyamide (nylon 6T), providing high thermal stability and flame resistance suitable for industrial applications.

Headers, Male Pins Procurement Notes

Verify the specific contact plating configuration and housing color against official datasheets prior to ordering. Confirm that the mating connector specifications align with the 0.64mm square pin size requirement. Ensure the through-hole termination method matches the target PCB fabrication capabilities. Check for any updated environmental compliance declarations relevant to the manufacturing date code.

Headers, Male Pins Selection Notes

Select this component when a robust, high-current board-to-board connection is required in space-constrained vertical stacks. The dual-row configuration allows for higher density compared to single-row alternatives. Consider the 3mm PC tail length for adequate solder joint formation. Verify that the operating temperature environment remains within the specified -40°C to +105°C range for long-term reliability.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a family of connectors known for their durability and high performance in demanding environments. The series offers various configurations including sockets and headers with different row counts and mounting styles. The M20-9971046 specifically addresses needs for vertical, through-hole male headers with extended contact lengths for secure mating.

Headers, Male Pins Replacement Considerations

Compatible mating parts include Harwin socket receptacles such as M20-7831046 or M20-7851046. Ensure substitute components maintain the same 2.54mm pitch and dual-row layout. Cross-referencing with other manufacturers requires verifying identical electrical ratings and mechanical dimensions.
