BL 3 3 Z

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 3 3 Z is a 3-position female header connector designed for through-hole PCB mounting. It features a 0.100-inch (2.54 mm) contact pitch and utilizes stamped contact springs configured as fork contacts. The connector supports flexible configuration with a separable pitch of 0.635 mm, allowing for various contact counts. It is rated for a nominal voltage of 125 V AC and includes tin plating on the posts.

Headers, Receptacles, Female Sockets Feature Summary

• Stamped contact spring design configured as a fork contact for reliable connection
• Flexible configuration capability accommodating any required number of contacts via separable pitch
• Through-hole mounting style suitable for standard PCB assembly processes

Headers, Receptacles, Female Sockets Applications

• General electronic assemblies requiring board-to-board or wire-to-board connections
• Prototyping circuits due to configurable contact spacing
• Consumer electronics internal interconnects

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific pin count matches the requirement of three positions. Confirm that the through-hole footprint aligns with the target PCB layout. Ensure the tin-plated finish meets the environmental and solderability standards for the intended manufacturing process. Check compatibility with mating pins or wires regarding the fork contact geometry.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, cost-effective solution for multiple signal lines is needed. The fork contact design allows for easy insertion of spade terminals or mating pins. Consider the 125 V AC rating for electrical isolation requirements. The tin plating offers good solderability but may require consideration for long-term corrosion resistance in harsh environments compared to gold-plated alternatives.

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 use of stamped contact springs rather than precision-formed contacts, which reduces cost while maintaining reliability for general-purpose applications. The 'Z' suffix typically denotes specific packaging or variant details within the manufacturer's catalog structure.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 3-position count, 2.54 mm pitch, and through-hole mounting style. Verify that alternative fork-contact headers maintain similar current carrying capacity and voltage ratings. Ensure the replacement part's mechanical dimensions fit the existing PCB hole pattern without interference.
