M20-7821642

Overview

The M20-7821642 is a 16-position female socket header from the Harwin M20 series, designed for through-hole mounting. It features a 2.54mm (0.100 inch) pitch and a single row configuration. The connector utilizes gold-plated contacts with tin plating on the termination side, ensuring reliable electrical performance. 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 UL94 V-0 rated high-temperature liquid crystal polymer, providing durability and flame resistance for board-to-board or cable applications.

Feature Summary

• Through-hole mounting design for secure PCB integration
• Gold-plated contact surfaces for enhanced conductivity
• High-temperature liquid crystal polymer insulation material
• Single-row straight orientation for compact layouts

Applications

• Board-to-board interconnections
• Cable-to-board connections
• Industrial control systems
• Consumer electronics assemblies

Procurement Notes

Verify the specific ordering suffix to confirm contact plating and termination type. Ensure compatibility with mating male headers regarding pitch and row count. Check RoHS compliance status against current regulatory requirements. Confirm that the through-hole footprint matches the target PCB design specifications before procurement.

Selection Notes

Select this component when a single-row, 2.54mm pitch female socket is required for through-hole assembly. Consider the gold-plated contacts for environments demanding low contact resistance. Evaluate the thermal stability provided by the LCP housing if operating near the upper temperature limit. Compare against other M20 variants for different pin counts or mounting styles.

Part Context

This part belongs to the M20 series, which offers a range of 2.54mm pitch connectors for various mounting needs. The series includes both surface mount and through-hole options in single and double rows. The M20-7821642 specifically addresses the need for robust, vertically oriented female sockets in space-constrained electronic designs requiring reliable signal transmission.

Replacement Considerations

Direct substitutes may include other M20 series female sockets with identical 16-pin, single-row, through-hole configurations. Verify that any alternative maintains the same 2.54mm pitch and contact plating specifications to ensure mechanical and electrical compatibility.
