BL 3 5 G

Headers, Receptacles, Female Sockets Overview

The BL 3 5 G is a five-position female header connector manufactured by Fischer Elektronik. It utilizes stamped contact springs designed for a separable pitch of 0.635 mm, providing a total width of 12.7 mm. The contacts are constructed from CuSn alloy with a gold plating thickness of 7.87 μin (0.2 μm) on the post surface. Rated for a nominal current of 3 A and a voltage of 125 VAC, the component features an insulating test voltage of 1500 V. It is intended for through-hole mounting applications.

Headers, Receptacles, Female Sockets Feature Summary

• Stamped contact spring design allows for flexible configuration of contact counts
• Gold-plated fork contacts ensure reliable electrical connection
• Suitable for standard PCB assembly processes

Headers, Receptacles, Female Sockets Applications

• General electronic circuit interconnections
• Prototyping boards requiring modular connectivity
• Industrial control panel wiring

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific order matches the five-position configuration and the required gold plating thickness. Confirm compatibility with the target PCB hole diameter to ensure proper mechanical retention during soldering. Check RoHS compliance status if restricted substances are a concern for the final product environment.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile female header with high conductivity is required. The 0.635 mm pitch offers tighter spacing than standard 2.54 mm headers. Ensure the mating pin size aligns with the fork contact opening to prevent excessive force or poor contact.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the BL 3 series of female headers from Fischer Elektronik. The series is characterized by its stamped spring contact technology, which differs from traditional crimped or formed contacts. Variants in this series differ primarily by the number of positions available.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other Fischer Elektronik BL 3 series headers with different position counts, such as BL 3 35 Z. Cross-manufacturer replacements must match the 0.635 mm pitch and fork contact geometry to ensure physical fit.
