BL 2 40 Z

Headers, Receptacles, Female Sockets Overview

The BL 2 40 Z is a 40-position PCB header connector manufactured by Fischer Elektronik. It features a dual-row configuration with a 0.100-inch (2.54 mm) pitch and utilizes a stamped contact spring design with fork contacts for secure mating. The component is designed for through-hole mounting on printed circuit boards. Electrical specifications include an operating temperature range of -40°C to +200°C, with a peak tolerance of 260°C for 10 seconds during soldering processes. The insulation material meets UL 94 V-0 flammability standards.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against official Fischer Elektronik documentation to confirm pin count and row configuration. Ensure compatibility with existing PCB footprint designs before procurement. Cross-reference technical datasheets for thermal and electrical ratings to validate suitability for the intended application environment.

Headers, Receptacles, Female Sockets Selection Notes

Select this component based on the required 40-position capacity and 2.54 mm pitch requirements. Consider the through-hole mounting style and stamped contact spring technology for applications demanding robust mechanical retention. Evaluate the high-temperature rating and UL 94 V-0 classification if the assembly involves elevated thermal conditions or strict safety compliance.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Fischer Elektronik BL series, which specializes in straight through-hole PCB sockets and headers. The series utilizes stamped contact springs for durable connections. The BL 2 40 Z specifically denotes a 40-position variant within this family, sharing common design principles with other models like the BL 2 72 Z regarding contact technology and pitch standards.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 40-position count, 2.54 mm pitch, and dual-row through-hole format. Verify that alternative components maintain identical fork contact spring mechanics and UL 94 V-0 insulation ratings to ensure functional equivalence without redesigning the PCB layout.
