SL 11 139 21 S

Headers, Male Pins Overview

The Fischer Elektronik SL 11 139 21 S is a single-row male header connector designed for through-hole PCB mounting. It features 21 positions with a 0.100 inch (2.54 mm) pitch. The contacts are square-shaped pins made of copper-tin alloy, plated with tin to a thickness of 157.5 µin (4.00 µm). Key dimensions include a mating contact length of 0.319 inches (8.10 mm), a column contact length of 0.118 inches (3.00 mm), and an insulation height of 0.110 inches (2.80 mm). The total contact length measures 0.547 inches (13.90 mm).

Headers, Male Pins Feature Summary

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' against the manufacturer's official datasheet to confirm plating specifications and packaging details. Ensure the required contact count matches the 21-position variant. Cross-reference the part number with Fischer Elektronik's current inventory status to confirm availability and production lifecycle stage before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a single-row male header with a 2.54 mm pitch is required for through-hole applications. Confirm that the 21-pin count aligns with the circuit design requirements. Verify that the square contact shape and tin plating meet the electrical and environmental standards of the target application.

Headers, Male Pins Part Context

This component belongs to the SL 11 series by Fischer Elektronik, which offers various contact counts ranging from 1 to 36 positions. The series maintains a consistent 0.100 inch pitch and single-row architecture, allowing for scalable design integration within the same connector family while maintaining uniform mechanical footprint characteristics.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Fischer Elektronik SL 11 series headers with identical 2.54 mm pitch and 21 positions. Ensure any replacement maintains the same through-hole termination style and square contact geometry to preserve mechanical fit and mating reliability without modifying the PCB layout.
