BL 18 141 25

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 18 141 25 is a single-row PCB socket header designed for through-hole mounting. It features 25 positions with a standard 2.54 mm (0.100 inch) pitch. The connector utilizes gold-plated contacts made from beryllium copper to ensure reliable signal transmission and durability. This straight-profile component is engineered for board-to-board connections, accommodating wire diameters between 0.65 mm and 0.85 mm or square pins measuring 0.635 mm.

Headers, Receptacles, Female Sockets Feature Summary

• Single-row configuration for compact board-to-board interconnections
• Gold-plated beryllium copper contacts for corrosion resistance
• Through-hole straight mounting style for secure PCB attachment

Headers, Receptacles, Female Sockets Applications

• Board-to-board connectivity in electronic assemblies
• Interfacing with square pin headers of specified dimensions
• Connections utilizing wires within the 0.65 to 0.85 mm diameter range

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific contact count matches the required 25-position configuration before procurement. Confirm that the through-hole straight form factor aligns with the mechanical layout of the target printed circuit board. Ensure compatibility with mating connectors using 0.635 mm square pins or compatible wire gauges to guarantee proper engagement and electrical continuity.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a single-row, 25-pin interface is required for direct PCB mounting. Consider the 2.54 mm pitch constraint for trace routing and spacing requirements. Evaluate the mechanical stability provided by the through-hole design against surface-mount alternatives if higher vibration resistance is necessary for the application environment.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Fischer Elektronik BL 18 141 series, which offers various contact counts ranging from lower pin configurations up to higher density options like the 36-position variant. The series maintains consistent dimensional standards and material specifications across different pole counts, allowing for scalable design architectures within the same product family.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 25-position count, 2.54 mm pitch, and through-hole straight profile. Verify that alternative manufacturers offer identical contact plating and housing materials to maintain environmental performance and mechanical fit without modifying the existing PCB footprint.
