BL 3 31 G

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 3 31 G is a single-row, through-hole female header connector featuring 31 positions with a 0.635 mm (0.025 inch) pitch. It utilizes stamped contact springs designed as fork contacts for flexible configuration. The connector supports a nominal current of 3 A and a nominal voltage of 125 V AC, with a test voltage rating of 1500 V. Electrical specifications include a volume resistance of ≤10 mΩ and inter-contact capacitance of ≤0.9 pF. The unit is packaged in bulk.

Headers, Receptacles, Female Sockets Feature Summary

• Constructed from stamped contact springs configured as fork contacts to enable flexible arrangement.

Headers, Receptacles, Female Sockets Applications

• General-purpose electronic circuit interconnections
• Custom connector assemblies requiring specific pin counts

Headers, Receptacles, Female Sockets Procurement Notes

Verify the exact position count matches the application requirement, as the BL 3 series allows for variable configurations based on the number of individual fork contacts assembled. Confirm that the 0.635 mm pitch aligns with mating hardware dimensions. Ensure the 3 A current rating and 125 V voltage limits are sufficient for the target circuit environment before finalizing procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a customizable female header with a fine 0.635 mm pitch is required. The fork contact design offers flexibility in creating custom lengths compared to fixed-position headers. Consider the through-hole mounting method and the specific electrical ratings of 3 A and 125 V AC to ensure compatibility with the system's power and signal requirements.

Headers, Receptacles, Female Sockets Part Context

The BL 3 series represents a family of customizable connector solutions from Fischer Elektronik. Unlike standard fixed-pin headers, these components consist of individual stamped spring contacts that can be arranged to form headers of varying lengths. This modular approach allows engineers to tailor the connector exactly to their board layout needs without wasting space or purchasing excess pins.

Headers, Receptacles, Female Sockets Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Due to the customizable nature of the BL 3 series, replacement may involve sourcing individual fork contacts from the same manufacturer rather than swapping to a different brand's fixed-header component.
