M22-5322146

Headers, Male Pins Overview

The M22-5322146 is a surface mount header connector from the Harwin M22 series, designed for high-density PCB applications. It features a dual in-line configuration with 42 positions arranged in two rows of 21 contacts each. The connector utilizes a precise 2.00mm (0.079 inch) pitch to ensure reliable mating. Constructed with gold-plated phosphor bronze contacts and a black polyamide insulation housing rated UL94 V-0, it supports a maximum operating temperature of 105°C. This component is engineered for robust board-to-board interconnections.

Headers, Male Pins Procurement Notes

Verify the specific suffix against official Harwin documentation to confirm exact plating thickness and material specifications. Ensure compatibility with standard SMT reflow profiles as defined in the datasheet. Cross-reference the DigiKey part number 952-2146-ND for accurate sourcing channels. Confirm that the 42-position layout matches the target PCB footprint requirements before procurement.

Headers, Male Pins Selection Notes

Select this model when a surface mount solution is required for 42-channel connections with a 2mm pitch. The dual-row format suits applications needing extensive I/O in a minimal footprint. Verify thermal resistance ratings against the intended operating environment. Consider the UL94 V-0 rating for fire safety compliance in enclosed assemblies.

Headers, Male Pins Part Context

This component belongs to the M22 series, which offers various configurations including through-hole and surface mount options. The series is characterized by its 2mm pitch and industrial-grade reliability. Similar parts in the family include different pin counts and mounting styles, but this specific model is distinct due to its 42-position SMT arrangement.

Headers, Male Pins Replacement Considerations

Direct substitutes within the M22 series may include other 42-position headers with compatible mounting styles. Verify mechanical dimensions and contact alignment for any alternative part numbers. Consult Harwin's obsolescence notices for potential end-of-life status or recommended upgrades.
