BL 4 72 Z

Headers, Receptacles, Female Sockets Overview

The BL 4 72 Z is a PCB female header connector manufactured by Fischer Elektronik. It features a dual-row configuration with 72 positions and a 2.54 mm (0.100 inch) pitch. The connector utilizes stamped contact springs with fork contacts designed for 0.635 mm wires. It employs a through-hole mounting technique with a 90-degree angled orientation. The insulating body is constructed from PPS material, rated for a nominal voltage of 125 V AC and a test voltage of 1500 V. The operating temperature range spans from -40°C to +200°C, with soldering resistance up to 260°C for 10 seconds.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix and contact plating details against the official Fischer Elektronik datasheet before procurement. Ensure the required wire gauge matches the 0.635 mm specification for the fork contacts. Confirm that the 90-degree angled form factor aligns with the mechanical constraints of the target PCB design. Cross-reference the voltage ratings with system requirements to ensure compliance with safety standards.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-count, low-profile connection is required on a PCB. The 90-degree angle facilitates vertical mating or space-constrained horizontal layouts. The PPS material offers superior heat resistance compared to standard thermoplastics. Consider the fork contact design for applications requiring frequent disconnection or field termination capabilities.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the BL series of PCB connectors from Fischer Elektronik, which specializes in stamped contact spring technology. The series is characterized by its modular nature, allowing for various pin counts and row configurations. The BL 4 72 Z represents a specific high-pin-count variant within this family, designed for robust signal and power distribution in compact electronic assemblies.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, 72-position count, dual-row structure, and 90-degree angled through-hole mounting. Verify compatibility with fork contacts and PPS housing material. Generic equivalents may differ in contact plating thickness or temperature ratings.
