SL 11 139 23 S

Headers, Male Pins Overview

The Fischer Elektronik SL 11 139 23 S is a single-row male header connector with a 0.635 mm (0.025 inch) pitch and 23 positions. It features through-hole mounting with tin-plated contacts on a copper alloy substrate. The insulating body is made of polyamide (PA46), rated UL 94 V-0, supporting an operating temperature range of -40°C to +163°C and a voltage rating of 250VAC. Key dimensions include a total contact length of 13.90 mm, a mating contact length of 8.10 mm, and an insulation height of 2.80 mm.

Headers, Male Pins Feature Summary

• Polyamide (PA46) insulating body with UL 94 V-0 flammability rating
• Through-hole mounting design for secure board attachment

Headers, Male Pins Applications

• General-purpose PCB signal and power distribution
• Industrial control system interconnects
• Consumer electronics internal wiring
• Test and measurement equipment interfaces

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' against the manufacturer's current datasheet to confirm plating specifications and material composition, as suffixes often denote critical variations in contact finish or housing material. Ensure compatibility with mating connectors regarding pitch and row count. Confirm RoHS compliance status if required by your assembly process, and check for any recent updates to the component's environmental ratings or mechanical tolerances.

Headers, Male Pins Selection Notes

Select this connector when a low-profile, single-row male header with a fine 0.635 mm pitch is required. The tin-plated contacts are suitable for general applications where gold plating is not necessary. Consider the thermal stability up to 163°C for reflow soldering processes. Ensure the PCB footprint matches the specified pin spacing and that the housing height fits within the enclosure constraints.

Headers, Male Pins Part Context

This component belongs to the SL 11 series of PCB headers from Fischer Elektronik. The series offers various contact counts and pitch options, designed for reliable electrical connections in compact electronic assemblies. The SL 11 139 23 S specifically provides a balance of density and mechanical stability for standard through-hole applications.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, 23-position count, and single-row male pin format. Verify that alternative components offer compatible contact plating (tin) and similar thermal ratings. Check mechanical dimensions, particularly insulation height and contact length, to ensure fit within the existing PCB layout and housing.
