SL 11 139 23 Z

Headers, Male Pins Overview

The Fischer Elektronik SL 11 139 23 Z is a single-row male header connector designed for through-hole PCB mounting. It features 23 positions with a 0.635 mm (0.025 inch) pitch, differing from the standard 2.54 mm spacing found in other series variants. The contacts are square-shaped pins made of copper-tin alloy, finished with tin plating to ensure reliable electrical connections. This component belongs to the SL 11 139 series, engineered for precision applications requiring specific contact density and mechanical stability.

Headers, Male Pins Feature Summary

• Single-row male header configuration for direct PCB integration
• Precision 0.635 mm contact pitch for high-density layouts
• Through-hole termination method ensuring secure mechanical fixation
• Tin-plated copper-tin contacts for corrosion resistance

Headers, Male Pins Applications

• High-density electronic assemblies requiring precise pin alignment
• Industrial control modules with space-constrained PCB designs
• Test and measurement equipment interfaces
• Custom adapter boards for specialized sensor arrays

Headers, Male Pins Procurement Notes

Verify the exact pin count and pitch against design schematics, as the 0.635 mm spacing differs significantly from common 2.54 mm headers. Confirm that the 'Z' suffix aligns with required termination or packaging specifications. Ensure compatibility with mating connectors matching the 0.635 mm grid. Request official datasheets to validate thermal and current ratings before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this model when a compact 0.635 mm pitch is mandatory rather than standard 2.54 mm spacing. Consider the through-hole requirement for mechanical strength over surface-mount alternatives. Evaluate the 23-position count against board space constraints. Verify that the tin plating meets environmental compliance standards for the target application environment.

Headers, Male Pins Part Context

This component is part of the Fischer Elektronik SL 11 139 series, which specializes in precision male headers. While similar models like SL 11 139 33 Z exist with different pin counts, this specific variant offers a tailored solution for circuits requiring exactly 23 contacts. The series is known for robust construction and consistent dimensional accuracy across varying position counts.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 0.635 mm pitch and 23-pin configuration. Generic 2.54 mm headers are incompatible due to pitch differences. Check Fischer Elektronik's updated catalog for newer revisions of the SL 11 139 series. Cross-reference with distributors for equivalent parts if original stock is unavailable, ensuring identical mechanical and electrical specifications.
