M50-3101645

Headers, Receptacles, Female Sockets Overview

The M50-3101645 is a dual-row female socket header from the Harwin Archer M50 series, designed for surface-mount technology. It features a 1.27 mm (0.05 inch) pin-to-pin spacing and accommodates 16 positions per row, totaling 32 contacts. The connector utilizes gold-plated phosphor bronze contacts housed in a black liquid crystal polymer (LCP) body. Rated for 1 kV voltage and 1 A current, it operates within a temperature range of -40°C to +105°C. The unit employs a straight orientation with solder termination, ensuring reliable board-to-board interconnections in compact electronic assemblies.

Headers, Receptacles, Female Sockets Feature Summary

• High-voltage insulation capability up to 1 kV for robust electrical isolation
• Gold-plated phosphor bronze contacts ensure low contact resistance and durability
• Liquid crystal polymer housing provides high thermal stability and UL 94 V-0 flammability rating
• Surface-mount design facilitates automated assembly processes

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnections in industrial control systems
• High-density signal routing in telecommunications equipment
• Interface modules requiring high-voltage isolation in medical devices
• Compact consumer electronics with strict space constraints

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm contact configuration and plating thickness. Ensure compatibility with the mating male header from the same M50 series family. Confirm that the surface-mount footprint matches the PCB layout guidelines provided in the component specification document. Cross-reference the RoHS compliance status if required by project regulations.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a dual-row, high-voltage capable connector is required for surface-mount applications. The 1.27 mm pitch allows for dense packing while maintaining adequate clearance for 1 kV ratings. Consider the LCP material properties for environments involving elevated temperatures or chemical exposure. Validate that the 1 A current rating meets the circuit requirements for all active pins simultaneously.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Archer M50 series, a line of fine-pitch connectors engineered for high-reliability applications. The series offers various configurations including headers, sockets, and cable assemblies. The M50-3101645 specifically addresses the need for secure, high-voltage connections in space-constrained designs, leveraging the series' standardized mechanical interface and material specifications for consistent performance across different product lines.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must maintain the 1.27 mm pitch, dual-row female configuration, and 1 kV rating. Verify that any alternative component matches the LCP housing material and gold-plated contact specifications to ensure equivalent thermal and electrical performance. Check for identical surface-mount footprint dimensions to avoid PCB redesign.
