SL 11 139 19 S

Headers, Male Pins Overview

The Fischer Elektronik SL 11 139 19 S is a single-row male header connector designed for through-hole mounting. It features 19 positions with a contact pitch of 0.100 inches (2.54 mm). The contacts are constructed from copper-tin alloy and feature selective gold plating to ensure reliable electrical performance. The connector utilizes a square contact shape and polyamide insulation material, providing structural stability in standard board-to-board or cable-to-board applications.

Headers, Male Pins Feature Summary

• Single-row configuration for compact circuit board integration
• Through-hole termination method for secure mechanical attachment
• Selective gold-plated contacts on copper-tin alloy substrate

Headers, Male Pins Applications

• General purpose electronic assemblies requiring 2.54 mm spacing
• Industrial control modules with standard pin headers
• Consumer electronics internal interconnects

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' indicates selective gold plating rather than tin, as this affects solderability and corrosion resistance requirements. Confirm the lead count matches the 19-position specification exactly. Ensure the through-hole footprint aligns with the target PCB design guidelines for thermal relief and pad sizing.

Headers, Male Pins Selection Notes

Select this component when a robust, gold-plated connection is required for a 19-channel interface. The 2.54 mm pitch is standard, but verify clearance against adjacent components. Consider the operating temperature range specified in the official datasheet if the application involves high-heat environments or reflow soldering profiles exceeding standard limits.

Headers, Male Pins Part Context

This part belongs to the SL 11 series of Fischer Elektronik headers. The series offers various contact counts and plating options. The '139' designation typically relates to specific housing dimensions or row configurations within the product family, distinguishing it from other pitch variants like 0.635 mm models.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 19-position count, 2.54 mm pitch, and through-hole mounting style. Verify that alternative manufacturers offer comparable gold plating thickness and copper-tin alloy contacts to maintain equivalent electrical and mechanical reliability standards.
