SL 11 139 25 S

Headers, Male Pins Overview

The SL 11 139 25 S is a male header connector from the Fischer Elektronik SL 11 series. It features a single row with 25 positions and a contact pitch of 0.100 inches (2.54 mm). The component utilizes through-hole termination for PCB mounting. Contacts are made of copper alloy with tin plating, offering a mating contact length of 0.319 inches (8.10 mm) and a column contact length of 0.118 inches (3.00 mm). The insulating body is constructed from polyamide (PA46), providing 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

• Single-row male pin configuration designed for reliable board-to-board or wire-to-board interconnections.
• Through-hole mounting technology ensures secure mechanical attachment to printed circuit boards.
• Tin-plated copper contacts provide corrosion resistance and stable electrical conductivity.
• Polyamide (PA46) insulating body offers structural integrity and thermal stability.

Headers, Male Pins Applications

• General-purpose electronic equipment signal routing
• Industrial control system interface connections
• Consumer electronics internal wiring harnesses

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' against the manufacturer's current datasheet to confirm exact plating thickness and material specifications. Ensure the required contact count matches the 25-position variant. Confirm that the through-hole footprint aligns with the target PCB design guidelines before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a single-row, 2.54 mm pitch male header is required for through-hole assembly. Consider the PA46 insulation material for standard operating temperatures. Evaluate the tin contact finish for general-purpose applications where gold plating is not strictly necessary. Verify spatial constraints against the total contact length and insulation height dimensions.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik SL 11 series, which provides various configurations of male headers with 2.54 mm spacing. The series supports contact counts ranging from 1 to 36 positions in a single row. The SL 11 139 designation indicates the specific dimensional profile within this family, standardized for industrial and commercial electronic assemblies requiring robust mechanical connections.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Fischer Elektronik SL 11 series headers with identical 2.54 mm pitch and through-hole termination. Ensure replacement parts maintain the same single-row layout and compatible contact materials. Cross-reference physical dimensions such as insulation height and total contact length to guarantee PCB footprint compatibility.
