BL 5 025 28

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 5 025 28 is a 28-position female header connector designed for through-hole PCB mounting. It features a 0.100-inch (2.54 mm) pitch and utilizes internal spring contacts with a nickel base and 0.25 µm gold plating on the contact surface. The component is constructed from PA 4.6 plastic housing rated UL 94 V-0, offering high dielectric strength of 2000 V AC and insulation resistance exceeding 10^7 Ω·m. Rated for 3 A at 250 V AC, it ensures reliable signal transmission in dense electronic assemblies.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix '28' confirms the 28-position count. Ensure the ordering part number matches the exact datasheet specification for the BL 5 025 series to confirm pin configuration and housing dimensions. Cross-reference the manufacturer's official catalog for any recent design changes or updated compliance certifications before finalizing procurement.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 28-pin through-hole female header is required. The 2.54 mm pitch suits standard PCB layouts. Verify that the 3 A current rating and 250 V AC voltage limit meet the circuit requirements. Consider the UL 94 V-0 flammability rating if fire safety standards are applicable to the end product environment.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Fischer Elektronik BL 5 025 series of female headers. The series offers various position counts, ranging from single pins to higher-density configurations. All variants share the same internal spring contact technology and material specifications, differing primarily in the number of contacts and overall physical length.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes within the same family include other positions in the BL 5 025 series, such as BL 5 025 20 or BL 5 025 36, provided the pin count difference is acceptable. No alternative manufacturers are confirmed in the provided data.
