SL 1 154 4 G

Headers, Male Pins Overview

The SL 1 154 4 G is a single-row male pin header connector manufactured by Fischer Elektronik. It features a 0.635 mm (0.025 inch) pitch and contains 36 positions. The connector utilizes gold-plated contacts on the post with a thickness of ≥0.2µm, while the column finish is tin-plated with a thickness of 46µm. Constructed from copper-tin contact material and polyamide (PA46) insulation, it supports a nominal current of 3 A and a nominal voltage defined in its specifications. The total contact length is 0.547 inches (13.90 mm), with a mating contact length of 0.319 inches (8.10 mm).

Headers, Male Pins Feature Summary

• Single-row configuration with square-shaped male pins for precise alignment.
• Gold-plated surface contacts ensure reliable signal transmission.
• Polyamide insulation material provides structural stability.
• Standard version designed for through-hole PCB mounting.

Headers, Male Pins Applications

• Precision electronic interconnects requiring tight pitch spacing.
• Board-to-board stacking applications.
• High-density circuit board assemblies.

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm contact finish variations, as different suffixes may indicate distinct plating options such as gold or tin. Ensure the selected variant matches the required nominal current and voltage ratings for the target application. Cross-reference the datasheet for exact dimensional tolerances and operating temperature ranges before finalizing procurement decisions.

Headers, Male Pins Selection Notes

Select this component when a 0.635 mm pitch is required for high-density connections. The single-row design simplifies routing compared to multi-row alternatives. Consider the thermal resistance during soldering, as the specified peak temperature limit is 260°C for 10 seconds. Evaluate the mechanical stability provided by the PA46 insulation against environmental stressors in the deployment environment.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik SL series, which specializes in precision headers and connectors. The SL 1 154 4 G represents a standard male pin variant within this lineup, distinguished by its specific 0.635 mm pitch and 36-position count. It complements other series members that offer varying row counts, pitches, and contact finishes to suit diverse electronic assembly needs.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, 36 positions, and single-row configuration. Verify compatibility of the housing material and contact plating thickness to ensure equivalent electrical performance and mechanical durability in existing designs.
