SL 1 154 20 S

Headers, Male Pins Overview

The SL 1 154 20 S is a single-row male header connector manufactured by Fischer Elektronik. It features a 0.635 mm (0.025 inch) pitch with 20 positions. The connector utilizes through-hole termination and has a gold-plated contact surface. Key dimensions include an overall pin length of 0.787 inches (20.00 mm), a mating pin length of 0.394 inches (10.00 mm), and a solder tail length of 0.130 inches (3.30 mm). The insulation height is 0.110 inches (2.80 mm).

Headers, Male Pins Feature Summary

• Single-row configuration for compact circuit board layouts.
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance.
• Through-hole mounting provides secure mechanical attachment to the PCB.

Headers, Male Pins Applications

• General electronic interconnects requiring precise spacing.
• Industrial control systems utilizing standard header configurations.
• Test and measurement equipment interfaces.

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' against the manufacturer's datasheet to confirm it denotes the correct contact plating or material variant, as suffixes in Fischer Elektronik part numbers often define critical electrical properties. Ensure the 0.635 mm pitch requirement matches the mating connector specifications to prevent compatibility issues during assembly.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-density connection is required with a 0.635 mm pitch. The gold plating is suitable for applications demanding stable conductivity without tin whisker concerns. Compare the total height and mating length against available clearance on the target PCB to ensure proper fitment with mating sockets.

Headers, Male Pins Part Context

This part belongs to the SL 1 series of one-row male headers from Fischer Elektronik. This series is characterized by its fine 0.635 mm pitch, offering higher density compared to standard 2.54 mm connectors. The SL 1 series is widely used in applications where space constraints necessitate smaller footprint connectors while maintaining robust electrical performance.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, 20-position count, and single-row layout. Verify that alternative manufacturers offer compatible gold plating thickness and through-hole pin dimensions to ensure interchangeability without modifying the PCB footprint.
