M20-8772942

Headers, Male Pins Overview

The M20-8772942 is a surface mount header connector from the Harwin M20 series. It features a single row with 29 positions and a 2.54 mm (0.100 inch) pitch. The connector utilizes square male pins made of brass with gold plating on the mating interface and tin plating on the tail. Rated for 3A current and 250V voltage, it operates within a temperature range of -40°C to 105°C. The housing is constructed from black polyamide (PA6T) nylon with UL94 V-0 flammability rating. Designed for board-to-board or cable applications, it offers a push-pull locking mechanism and a mating pin length of 5.80 mm.

Headers, Male Pins Feature Summary

• Push-pull locking system ensures secure mechanical retention during mating cycles.
• Gold-plated square contacts provide reliable electrical conductivity and corrosion resistance.
• High-temperature resistant PA6T insulation supports operation up to 105°C.
• Surface mount termination facilitates automated PCB assembly processes.

Headers, Male Pins Applications

• Board-to-board interconnections in compact electronic modules
• Cable-to-board connections requiring robust retention
• Industrial control systems operating in elevated temperatures

Headers, Male Pins Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm pin count and orientation. Ensure compatibility with mating socket assemblies from the same M20 series family. Confirm that the surface mount footprint matches the target PCB design guidelines. Check for any updated environmental compliance declarations prior to final procurement approval.

Headers, Male Pins Selection Notes

Select this component when a single-row surface mount header with push-pull retention is required. The 2.54 mm pitch suits standard density layouts. Consider the 3A current rating for power distribution needs. Verify that the 5.80 mm mating length accommodates the target stack-up height without interference.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a line of high-reliability connectors known for their push-pull locking feature. The series offers various row counts and mounting styles. The M20-8772942 specifically addresses the need for a single-row SMD solution with secure locking capabilities in space-constrained designs.

Headers, Male Pins Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Cross-reference with other M20 series headers if pin count variations are acceptable. Ensure any alternative maintains the same pitch, locking mechanism, and thermal ratings.
