SL 11 139 21 Z

Headers, Male Pins Overview

The SL 11 139 21 Z is a single-row male pin header connector manufactured by Fischer Elektronik. It features a 2.54 mm (0.100 inch) pitch and contains 21 positions designed for through-hole mounting on printed circuit boards. The contacts are constructed from copper-tin alloy with a tin plating finish, providing reliable electrical connectivity. The connector utilizes a square contact shape and polyamide insulation material to ensure mechanical stability and dielectric strength.

Headers, Male Pins Feature Summary

• Single-row male pin configuration for standard board-to-board or wire-to-board interconnections
• Through-hole termination method ensuring secure mechanical attachment to the PCB
• Tin-plated copper-tin alloy contacts for corrosion resistance and conductivity

Headers, Male Pins Applications

• General-purpose electronic assembly requiring 21-pin signal or power routing
• Industrial control systems utilizing Fischer Elektronik connector series
• Prototyping and manufacturing environments needing standardized 2.54 mm spacing

Headers, Male Pins Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's current datasheet to confirm exact plating thickness and material specifications. Ensure the required contact count matches the 21-position variant, as this series offers multiple pin counts. Confirm that the through-hole footprint aligns with your PCB design guidelines before ordering.

Headers, Male Pins Selection Notes

Select this component when a single-row, 21-position male header with 2.54 mm pitch is required. The tin-plated contacts suit applications where gold plating is unnecessary. Consider the overall height and mating length constraints relative to adjacent components on the assembly.

Headers, Male Pins Part Context

This part belongs to the SL 11 139 series of rectangular connectors from Fischer Elektronik. The series provides various pin counts while maintaining consistent pitch and housing dimensions. It is designed for robust industrial and commercial electronics applications requiring reliable interconnect solutions.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include SL 11 139 18 Z and SL 11 139 36 Z for different pin counts. Cross-manufacturer replacements must match the 2.54 mm pitch, 21 positions, and through-hole mounting style to ensure physical compatibility.
