SL 11 139 31 G

Headers, Male Pins Overview

The SL 11 139 31 G is a single-row male pin header manufactured by Fischer Elektronik. It features 31 positions with a 2.54 mm (0.100 inch) pitch and 0.635 mm square contact cross-sections. The connector utilizes copper-tin contacts with selective gold plating, rated for 3 A current and 250 V AC voltage. Constructed with PA 4.6 insulation, it supports through-hole mounting and reflow soldering processes.

Headers, Male Pins Feature Summary

• Selective gold plating on copper-tin contacts ensures reliable electrical performance and low contact resistance.
• PA 4.6 insulating body provides thermal stability and mechanical durability for standard PCB assembly.
• Single-row male pin design facilitates straightforward through-hole installation and mating.

Headers, Male Pins Applications

• General-purpose PCB interconnections requiring robust male pin headers
• Industrial control systems utilizing standard 2.54 mm spacing
• Electronic assemblies compatible with reflow soldering techniques

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm the contact finish type, as variations exist within the series. Ensure compatibility with the target PCB footprint and mating connector specifications. Confirm that the selected variant meets the required voltage and current ratings for the intended application environment before finalizing procurement.

Headers, Male Pins Selection Notes

Select this component when a single-row male header with 31 positions is required. The 2.54 mm pitch is standard for many electronic interfaces. Consider the gold-plated variant for applications demanding lower contact resistance and enhanced corrosion resistance compared to tin-only options. Verify insulation material suitability for the operating temperature range.

Headers, Male Pins Part Context

This part belongs to the SL 11 139 series of male headers from Fischer Elektronik. The series offers configurations ranging from 1 to 36 contacts in a single row. These connectors are designed for through-hole mounting and are characterized by their 0.635 mm contact cross-section and 2.54 mm grid spacing, suitable for various general-purpose electronic applications.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Fischer Elektronik parts within the SL 11 139 series with matching position counts, such as SL 11 139 31 S or SL 11 139 31 Z, provided the contact finish requirements align. Cross-manufacturer replacements must match the 2.54 mm pitch, 31-position count, and through-hole mounting style.
