SL 11 190 25 S

Headers, Male Pins Overview

The SL 11 190 25 S is a single-row male pin header manufactured by Fischer Elektronik. It features 25 contacts with a 0.635 mm (0.025 inch) pitch and a 2.54 mm (0.100 inch) mating spacing. The connector utilizes through-hole straight termination for PCB mounting. Contact materials are copper alloy, plated with tin to provide corrosion resistance and reliable conductivity. The housing is constructed from polyamide (PA46), offering thermal stability and mechanical strength. This component is designed for board-to-board or wire-to-board interconnections in electronic assemblies.

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' against the manufacturer's current datasheet to confirm contact plating thickness and material specifications. Ensure the required contact count matches the 25-position variant. Confirm that the through-hole straight profile aligns with the target PCB layout and assembly requirements before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a single-row male header with a 0.635 mm pitch is required. The 25-contact configuration suits applications needing moderate density interconnects. Verify that the through-hole mounting style and straight orientation fit the mechanical constraints of the design. Ensure compatibility with mating connectors using the specified 2.54 mm spacing.

Headers, Male Pins Part Context

This part belongs to the SL 11 190 series of precision-engineered headers from Fischer Elektronik. The series is characterized by its use of polyamide insulation and tin-plated contacts. Variants within the series differ primarily by the number of contacts and specific suffix codes indicating plating or housing variations. The SL 11 190 25 S represents a mid-range contact count option within this standardized product line.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, 25 positions, and through-hole straight termination. Verify that alternative manufacturers offer identical tin-plated copper contacts and PA46 insulation. Cross-reference dimensions A, B, and C from official drawings to ensure mechanical interchangeability without modifying the PCB footprint.
