M22-2021505

Headers, Male Pins Overview

The M22-2021505 is a Harwin Inc. pin header connector from the M22 series, designed for board-to-board applications. It features a vertical orientation with a 2.00 mm (0.079 inch) pitch and a 2-row configuration containing 30 total positions (15+15). The connector utilizes male pins with gold plating on phosphor bronze contacts, rated at 1A per contact. It employs a through-hole solder termination method and includes a push-pull locking mechanism. The housing is constructed from black nylon (PA6T), offering a UL94 V-0 flammability rating and an operating temperature range of -40°C to 105°C.

Headers, Male Pins Feature Summary

• Features a push-pull locking system for secure mechanical retention during mating cycles.
• Constructed with high-temperature resistant PA6T insulation suitable for reflow soldering processes.
• Utilizes gold-plated phosphor bronze contacts to ensure reliable electrical conductivity and corrosion resistance.

Headers, Male Pins Applications

• High-density board-to-board interconnections in compact electronic assemblies
• Industrial control systems requiring robust vertical mounting solutions
• Consumer electronics with strict height limitation constraints

Headers, Male Pins Procurement Notes

Verify the specific position count and row configuration against the datasheet, as suffix variations within the M22 series may alter pin counts or mating lengths. Confirm that the push-pull locking feature is required for the assembly, as standard headers lack this mechanism. Ensure compatibility with mating sockets that support the specific 3.5mm mating pin length associated with this series.

Headers, Male Pins Selection Notes

Select this component when a vertical, double-row header with a 2.00 mm pitch is necessary for space-constrained designs. The push-pull locking mechanism distinguishes it from standard fixed headers, providing enhanced retention without additional hardware. Consider the 1A current rating and 500V voltage limit to ensure compliance with the circuit's electrical requirements.

Headers, Male Pins Part Context

This part belongs to the Harwin M22 series, which provides industrial-standard PCB socket connectors with fine 2 mm spacing. The series is engineered to meet modern PCB density requirements while maintaining low profile heights. The M22 line offers various configurations including single and double rows, with options for different locking mechanisms and termination styles to suit diverse manufacturing needs.

Headers, Male Pins Replacement Considerations

Compatible mating sockets include M22-6361042 and M22-6341042, which are 20-position variants. Note that these substitutes differ in position count; verify that the reduced pin count meets the design requirements before substitution. No direct identical replacement is confirmed in the provided data.
