BL 4 38 G

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 4 38 G is a board-to-board header connector designed for surface-mount applications. It features 38 positions arranged in two rows with a 2.54 mm pitch. The contacts are gold-plated copper tin, ensuring reliable conductivity and corrosion resistance. The insulating body is constructed from PPS material, offering high thermal stability and UL 94 V-0 flammability rating. This component supports nominal currents of 3 A and operates within a temperature range of -40°C to +200°C.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix 'G' corresponds to the required contact plating and packaging format. Confirm that the right-angle orientation matches the mechanical layout constraints of the target PCB. Ensure compatibility with standard reflow soldering profiles for PPS materials. Cross-reference the 38-position count with schematic requirements to avoid pin mismatch during integration.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when surface-mount assembly is preferred over through-hole for space efficiency. The 2.54 mm pitch ensures compatibility with standard mating connectors. Consider the high operating temperature range if the application involves significant thermal stress. Verify that the gold plating thickness meets the required cycle life expectations for the specific mating interface.

Headers, Receptacles, Female Sockets Part Context

Fischer Elektronik specializes in precision connectors and thermal management solutions. The BL series represents their line of board-to-board headers. This model belongs to a family of connectors designed for robust electrical connections in demanding environments. The manufacturer emphasizes material quality and dimensional accuracy for consistent performance across production batches.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 38-position count, 2.54 mm pitch, and surface-mount right-angle form factor. Verify identical contact plating (gold) and insulating material (PPS) for thermal compatibility. Check for equivalent current ratings and temperature specifications. Generic equivalents may lack the specific UL 94 V-0 rating or precise mechanical tolerances required for secure mating.
