SL 11 139 1 S

Headers, Male Pins Overview

The SL 11 139 1 S is a male header connector from Fischer Elektronik, designed for through-hole PCB mounting. It features a single row with one contact position and a pitch of 0.100 inches (2.54 mm). The connector utilizes square pin contacts made of copper-tin alloy, plated with tin on both the mating and post surfaces. Key dimensions include a total contact length of 0.547 inches (13.90 mm), a mating contact length of 0.319 inches (8.10 mm), and an insulation height of 0.110 inches (2.80 mm). The housing is constructed from polyamide (PA46) nylon.

Headers, Male Pins Feature Summary

• Single-row male header configuration for direct PCB integration
• Square pin contact geometry for secure mechanical retention
• Through-hole termination method for robust board attachment

Headers, Male Pins Applications

• General electronic circuit interconnections
• Prototype development boards
• Low-density signal routing applications

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm plating thickness and material composition, as variations exist within the SL 11 series. Ensure compatibility with standard 2.54 mm pitch sockets. Confirm that the single-position requirement matches the design intent, as multi-position variants are common in this family. Check datasheet specifications for thermal resistance during reflow soldering processes.

Headers, Male Pins Selection Notes

Select this component when a single-channel connection is required in a dense array environment. The 2.54 mm pitch ensures compatibility with standard breadboards and ribbon cables. Consider the PA46 insulation material for improved heat resistance compared to standard nylons. Verify that the through-hole footprint aligns with the PCB layout constraints and available clearance around the connector site.

Headers, Male Pins Part Context

This part belongs to the SL 11 series of precision-engineered male headers by Fischer Elektronik. The series offers various contact counts ranging from one to thirty-six positions while maintaining consistent dimensional standards. The SL 11 139 designation indicates specific housing and contact length characteristics within the product line, ensuring interchangeability with other connectors in the same series family.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other single-row, 2.54 mm pitch male headers from manufacturers such as TE Connectivity or Molex, provided they match the square pin profile and through-hole termination style. Verify that alternative parts meet the same UL 94 V-0 flammability rating and temperature range specifications (-40°C to +163°C) to ensure equivalent performance in the target application.
