M50-3101045

Headers, Receptacles, Female Sockets Overview

The M50-3101045 is a 20-position dual-in-line (DIL) board-to-board receptacle connector from the Harwin ARCHER M50 series. It features a 1.27 mm (0.05 inch) pin spacing and is designed for surface mount technology (SMT) installation. The connector utilizes female socket contacts made of phosphor bronze with gold plating, ensuring reliable electrical performance. Rated for 1 A current and 250 V voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black UL 94 V-0 rated liquid crystal polymer (LCP), providing high thermal stability and flame resistance.

• Dual-row DIL configuration for compact board-to-board interconnection
• Gold-plated phosphor bronze contacts for corrosion resistance and conductivity
• UL 94 V-0 LCP housing material for enhanced thermal and flame performance

Headers, Receptacles, Female Sockets Applications

• High-density electronic assemblies requiring surface mount connectivity
• Industrial control systems utilizing board-to-board interfaces
• Consumer electronics with strict space constraints

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix and packaging format when ordering, as tape-and-reel quantities may vary by distributor. Confirm that the required contact count matches the 20-position specification. Ensure soldering profiles align with the LCP material limits to prevent warping during SMT reflow processes.

Headers, Receptacles, Female Sockets Selection Notes

Select this component for applications demanding high reliability in small form factors. The 1.27 mm pitch offers a balance between density and manufacturability. Consider the UL 94 V-0 rating if fire safety standards are critical. Verify mating connector compatibility with the ARCHER series male headers.
