M20-9772242

Headers, Male Pins Overview

The Harwin M20-9772242 is a vertical pin header assembly from the M20 series, featuring a 2.54mm pitch and 22 positions in a single row. Designed for through-hole mounting, it utilizes brass contacts with gold plating on mating surfaces and tin plating on tails. The connector supports board-to-board or wire-to-board applications, rated at 3A per contact and 250V, operating within a temperature range of -40°C to 105°C.

Headers, Male Pins Feature Summary

• Vertical orientation facilitates direct PCB insertion for standard board-to-board connections.
• Gold-plated mating contacts ensure reliable signal transmission and corrosion resistance.
• Tin-plated through-hole tails provide secure soldering joints for mechanical stability.

Headers, Male Pins Applications

• Board-to-board interconnections in compact electronic modules
• Wire-to-board harness attachments requiring vertical alignment
• General-purpose signal routing in industrial control units

Headers, Male Pins Procurement Notes

Verify that the specific suffix '242' corresponds to the required 22-position configuration and gold/tin plating combination. Confirm through-hole tail dimensions match the target PCB drill pattern. Ensure compatibility with mating receptacles from the same M20 series family to maintain proper engagement height and electrical continuity.

Headers, Male Pins Selection Notes

Select this component when a vertical, single-row header is required for 22 signals. It is suitable for applications needing robust through-hole termination rather than surface mount alternatives. Consider the 2.54mm pitch constraint and verify that the 3A current rating meets the circuit requirements without derating issues.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used line of 2.54mm pitch connectors known for their versatility in both board-to-board and wire-to-board applications. The M20 series offers various configurations including headers, sockets, and shrouded options, providing standardized solutions for dense interconnect needs across multiple industries.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Harwin M20 series headers with identical 2.54mm pitch and 22 positions, such as M20-9772246 if silver plating is acceptable. Cross-brand replacements must match the 2.54mm spacing, vertical form factor, and through-hole tail specifications to ensure mechanical fit and electrical performance.
