BL 1 31 Z

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 1 31 Z is a single-row, 31-position through-hole header connector designed for board-to-board or cable-to-board interconnections. It features a 0.100 inch (2.54 mm) pitch and utilizes stamped contact springs with tin plating. The component is constructed with a polyamide insulating body and square-profile contacts compatible with 0.635 mm pins. Rated for 1.5A current and suitable for reflow soldering at 260°C, it offers reliable electrical performance in standard electronic assemblies.

Headers, Receptacles, Female Sockets Feature Summary

• Stamped contact spring design allows for manual cutting to length from bar magazines
• Tin-plated contacts provide corrosion resistance and reliable conductivity
• Square profile compatibility ensures secure mating with 0.635 mm pin diameters

Headers, Receptacles, Female Sockets Applications

• General purpose board-to-board interconnects
• Cable-to-board connections requiring through-hole mounting
• Custom assembly applications needing cut-to-length pin strips

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix 'Z' confirms tin plating rather than gold or other finishes. Confirm the part number corresponds to the 31-position variant within the BL 1 series. Ensure the supplier provides documentation confirming RoHS compliance and UL 94 V-0 flammability rating for the polyamide insulator. Cross-reference the manufacturer datasheet to validate the 1.5A current rating and 260°C thermal endurance specifications before finalizing procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a through-hole male header with a 2.54 mm pitch is required. The stamped contact construction supports cost-effective custom lengths compared to pre-cut individual pins. Consider the 0.635 mm contact profile requirement to ensure mating compatibility. Evaluate the 1.5A current rating against circuit requirements. This series is suitable for applications where manual assembly of pin strips is preferred over surface-mount alternatives.

Headers, Receptacles, Female Sockets Part Context

The BL 1 series represents Fischer Elektronik's line of precision-engineered stamped contact springs. These components are distinct from molded connectors, offering flexibility in length customization. The series includes various positioning options and plating choices, with the 'Z' suffix specifically denoting tin plating. This product falls under the broader category of rectangular pin strips used in industrial and consumer electronics manufacturing.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other Fischer Elektronik BL 1 series headers with identical pitch and position counts but different plating, such as BL 1 31 G for gold plating. Generic equivalents must match the 2.54 mm pitch, 31 positions, and through-hole mounting style. Verify that alternative suppliers offer stamped contact technology rather than formed wire if cut-to-length functionality is required.
