M22-2040546

Headers, Male Pins Overview

The M22-2040546 is a Harwin Inc. header connector from the M22 series, designed for board-to-board applications. It features a 2 mm (0.079 in) pitch with a 10-position configuration arranged in two rows (5+5). The connector utilizes male pin contacts with tin plating and phosphor bronze material. It employs a right-angle solder termination type for through-hole mounting. The housing is constructed from black nylon, rated UL 94 V-0 for flammability. Electrical ratings include 650 VAC voltage and 1 A current per contact. Operating temperature ranges from -40°C to +105°C.

Headers, Male Pins Feature Summary

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm the tin-plated finish and horizontal orientation. Ensure compatibility with mating sockets regarding pin length and row spacing. Check for RoHS compliance status if required by project specifications. Confirm availability and lead times directly with authorized distributors as supply chain conditions may vary.

Headers, Male Pins Selection Notes

Select this component when a right-angle, double-row header is required for space-constrained designs. The 2 mm pitch offers a balance between density and ease of assembly. Verify that the 1 A current rating meets the circuit requirements. Consider the through-hole mounting method for robust mechanical fixation compared to surface mount alternatives.

Headers, Male Pins Part Context

This connector belongs to the M22 series, which is characterized by fine 2 mm pitch spacing. The series supports various configurations including single and double rows with different contact counts. It is engineered for high reliability in demanding environments, utilizing durable materials and precise manufacturing tolerances to maintain consistent performance over time.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include M22-2040446, which shares identical physical dimensions and electrical characteristics but differs in contact plating. Ensure any replacement maintains the right-angle orientation and through-hole termination style to fit existing PCB footprints.
