BL 19 141 48

Headers, Receptacles, Female Sockets Overview

The BL 19 141 48 is a high-precision female header connector manufactured by Fischer Elektronik, designed specifically for PC/104 module applications. It features two rows with 48 contacts and a 0.100-inch (2.54mm) pitch. The connector supports through-hole mounting and utilizes gold-plated contacts to ensure reliable signal transmission. Key electrical specifications include an insert depth of 2.56mm, an insertion force of 1.3N, and a drawing force of 0.3N. Mechanical shock resistance is rated at 50g. The design accommodates plugability for circuit points with diameters ranging from 0.55mm to 0.65mm and Ø0.65mm to 0.85mm.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific contact count matches the '48' designation in the model number to ensure compatibility with your board layout. Confirm that the 0.100-inch pitch aligns with your PCB footprint requirements. Check that the through-hole mounting style suits your assembly process. Ensure the connector's mechanical shock resistance rating meets the environmental standards of your final application. Validate that the gold plating specification is necessary for your signal integrity needs.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when designing for PC/104 form factor constraints requiring a 48-pin interface. Consider the 2.56mm insert depth to ensure adequate mating engagement with corresponding male headers. Evaluate the 1.3N insertion force against manual handling or automated pick-and-place capabilities. Compare the 50g shock resistance against potential vibration environments. Ensure the two-row layout fits within the available vertical space on the target PCB.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the BL 19 141 series of female headers from Fischer Elektronik. The series is characterized by its specialization for PC/104 modules, offering varying contact counts from 2 to 72. The BL 19 141 48 represents a mid-range density option within this family, providing a balanced solution for complex embedded applications without occupying excessive board area compared to higher pin-count variants.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 48-pin count, 2.54mm pitch, and PC/104 compatibility. Verify identical mechanical dimensions, particularly the 2.56mm insert depth and row spacing. Ensure equivalent contact material and plating thickness for reliable performance.
