SL 1 179 21 S

Headers, Male Pins Overview

The SL 1 179 21 S is a single-row header connector manufactured by Fischer Elektronik. It features 21 positions with a 0.635 mm (0.025 inch) pitch, designed for through-hole mounting on PCBs. The contacts are gold-plated pins housed in black polyamide insulation. This component provides reliable electrical interconnection for low-current applications requiring precise spacing.

Headers, Male Pins Feature Summary

• Single-row configuration with 0.635 mm pitch
• Gold-plated contact surfaces for corrosion resistance
• Through-hole termination method for secure PCB attachment

Headers, Male Pins Applications

• PCB-to-PCB interconnections
• Low-current signal routing
• Precision electronic module assembly

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' against official Fischer Elektronik documentation to confirm exact plating thickness and material specifications. Ensure compatibility with mating connectors of matching 0.635 mm pitch. Confirm RoHS compliance status via current datasheets before integration into regulated products.

Headers, Male Pins Selection Notes

Select this part when a compact 0.635 mm pitch is required instead of standard 2.54 mm headers. Consider the single-row layout for space-constrained designs. Verify that the gold plating meets the environmental and conductivity requirements of the target application circuitry.

Headers, Male Pins Part Context

This component belongs to the SL 1 179 series of precision headers from Fischer Elektronik. The series is characterized by its fine 0.635 mm pitch, distinguishing it from standard 2.54 mm connectors. It serves as a specialized solution for dense electronic assemblies where smaller form factors are critical.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, 21-position count, and single-row format. Generic 2.54 mm headers are incompatible due to dimensional differences. Verify pin length and insulation height if replacing with alternative manufacturers' parts.
