SL LP 1 139 25 S

Headers, Male Pins Overview

The SL LP 1 139 25 S is a single-row male header connector from the Fischer Elektronik SL LP 1 139 series. It features a 0.635 mm (0.025 inch) pitch and provides 25 positions for through-hole mounting. The contacts are constructed from copper alloy with gold plating on the mating surface and tin plating on the post section. The connector utilizes a square contact shape and polyamide insulation material rated UL 94 V-0. Key dimensions include an overall contact length of 13.90 mm, a mating contact length of 8.10 mm, and a post contact length of 3.00 mm.

Headers, Male Pins Feature Summary

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'S' corresponds to the required contact finish configuration. Confirm that the 0.635 mm pitch aligns with the mating connector specifications. Ensure the through-hole footprint matches the target PCB layout. Check RoHS compliance status if required by project standards. Validate the operating temperature range against environmental conditions.

Headers, Male Pins Selection Notes

Select this component when a low-profile male header with fine 0.635 mm pitch is required. Choose the gold-plated variant for applications demanding high corrosion resistance and stable electrical performance. Consider the through-hole construction for mechanical stability in vibration-prone environments. Ensure the 25-position count fits the circuit density requirements.

Headers, Male Pins Part Context

This part belongs to the SL LP 1 139 series of low-profile connectors. The series offers various pin counts and contact finishes to suit different application needs. Fischer Elektronik designs these headers for compact electronic assemblies requiring reliable interconnection.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, 25 positions, and through-hole mounting style. Verify compatibility of the square contact shape and low-profile height. Cross-reference the gold/tin plating combination with equivalent offerings from other manufacturers.
