BL 4 40 Z

Headers, Receptacles, Female Sockets Overview

The BL 4 40 Z is a 40-position through-hole header connector with a 2.54 mm (0.100 inch) pitch. It features a stamped contact spring design and tin-plated contacts over a nickel underlayer, ensuring conductivity and corrosion resistance. The insulating body is constructed from PPS material, supporting a temperature range of -40°C to +200°C, with a peak tolerance of 260°C for 10 seconds. The component meets UL 94 V-0 flammability standards.

Headers, Receptacles, Female Sockets Feature Summary

• Fork contact design engineered for precise electrical connections
• Tin-plated contacts with nickel underlayer for corrosion resistance
• PPS insulating body rated for high thermal stability

Headers, Receptacles, Female Sockets Applications

• Through-hole PCB interconnections
• High-temperature electronic assemblies
• Signal routing in dense circuit boards

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pin count and termination style. Ensure compatibility with standard 2.54 mm grid layouts. Check RoHS compliance status if required by project specifications. Confirm that the tin plating thickness meets the application's conductivity requirements.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 40-position through-hole header is required for high-temperature environments. The PPS material and V-0 rating make it suitable for applications exceeding standard thermal limits. The fork contact design aids in reliable mating cycles. Verify board space constraints against the 0.100 inch pitch dimensions.

Headers, Receptacles, Female Sockets Part Context

This part belongs to Fischer Elektronik's BL series of PCB connection systems. The series offers various position counts and configurations for board-to-board or cable-to-board connections. The BL 4 40 Z specifically addresses the need for higher density interconnects with robust thermal performance capabilities.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 40-position count, 2.54 mm pitch, and through-hole termination. Verify that alternative components support the same PPS insulation and thermal ratings. Cross-reference pinout compatibility before integration.
