CWN-351-50-0021

Headers, Male Pins Overview

The CWN-351-50-0021 is a vertical header connector manufactured by CW Industries, designed for through-hole mounting. It features 50 positions arranged in two rows with a 2.54mm pitch. The contacts are gold-plated phosphor bronze pins, ensuring reliable signal transmission. The insulator is blue thermoplastic material rated UL94 V-0. This component supports a rated current of 1A and operates within a temperature range of -55°C to 125°C. Key mechanical features include keying slots and mounting flanges for secure installation.

Headers, Male Pins Feature Summary

• Vertical pin header configuration with 50 positions for high-density connections
• Gold-plated phosphor bronze contacts for enhanced conductivity and corrosion resistance
• Blue thermoplastic insulation with UL94 V-0 flammability rating
• Integrated keying slots and mounting flanges for precise alignment and stability

Headers, Male Pins Applications

• General-purpose board-to-board interconnections
• Industrial control system circuit boards
• Consumer electronics internal wiring harnesses
• Telecommunications equipment interfaces

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and insulator color variations. Check manufacturer notices for any product change notifications or obsolescence alerts. Ensure compatibility with mating receptacles regarding row spacing and keying orientation. Confirm RoHS compliance status if required for your assembly process. Review datasheet specifications for peak reflow temperature limits during soldering.

Headers, Male Pins Selection Notes

Select this component when a vertical, 2-row header with 50 positions is required. The 2.54mm pitch is standard for many legacy and modern PCB layouts. Consider the 1A current rating for power distribution needs. The through-hole termination method suits automated wave or selective soldering processes. Verify that the board space accommodates the 0.681-inch insulation height.

Headers, Male Pins Part Context

This part belongs to the CWN series of rectangular connectors from CW Industries. The series offers various pin counts and configurations for different connectivity needs. The CWN-351 variant specifically denotes a vertical header style. It is distinct from IDC or surface-mount alternatives in the same family. The design focuses on robust mechanical retention and electrical reliability.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other 50-position, 2.54mm pitch vertical headers from different manufacturers. Ensure mechanical dimensions such as body width and height match the PCB footprint. Verify that mating connector pin count and arrangement are identical. Check for equivalent current ratings and temperature ranges before substitution.
