SL 1 104 21 S

Headers, Male Pins Overview

The SL 1 104 21 S is a single-row male pin header connector manufactured by Fischer Elektronik. It features 21 positions with a 2.54 mm (0.100 inch) contact pitch, designed for through-hole mounting on printed circuit boards. The contacts are gold-plated over nickel to ensure reliable signal transmission and corrosion resistance. This component belongs to the SL 1 series, offering standard straight termination for board-to-board or wire-to-board interconnections.

Headers, Male Pins Feature Summary

• Single-row male pin configuration for straightforward PCB integration
• Gold-over-nickel contact plating for enhanced durability and conductivity
• Through-hole soldering technique ensures secure mechanical attachment

Headers, Male Pins Applications

• General-purpose PCB interconnects
• Board-to-board signal routing
• Wire-to-board connections in electronic assemblies

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'S' corresponds to the required gold plating specification as per the official datasheet. Confirm that the 21-position count matches the design requirements. Ensure compatibility with standard 2.54 mm pitch mating connectors. Check RoHS compliance status if restricted substances are a concern for the target application.

Headers, Male Pins Selection Notes

Select this part when a single-row, 21-pin male header is required for through-hole assembly. The gold plating offers superior performance compared to tin-only variants in corrosive environments. Consider the physical dimensions and height constraints of the PCB layout before finalizing the selection for space-sensitive designs.

Headers, Male Pins Part Context

This component is part of Fischer Elektronik's extensive portfolio of PCB connectors. The SL series is widely recognized for its robust construction and precise manufacturing tolerances. As a male header, it serves as the counterpart to female sockets or cable assemblies, facilitating modular electronic system design.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, 21 positions, single-row male format, and through-hole termination. Verify that any alternative maintains the gold-over-nickel plating specification to ensure equivalent electrical and environmental performance characteristics.
