SL 11 139 31 Z

Headers, Male Pins Overview

The SL 11 139 31 Z is a single-row male header connector manufactured by Fischer Elektronik. It features a 0.100 inch (2.54 mm) pitch and accommodates 31 positions. The contacts are square-shaped pins with a tin plating thickness of 157.5 µin (4.00 µm). Constructed from copper-tin alloy, the connector utilizes a polyamide (PA46) insulating body. Key dimensions include an insertion depth of 3.00 mm, an insulation height of 0.110 inch (2.80 mm), and a total contact length of 0.547 inch (13.90 mm).

Headers, Male Pins Feature Summary

• Single-row male pin configuration for through-hole PCB mounting.
• Square contact cross-section designed for reliable mating engagement.
• Tin-plated copper-tin contacts ensure corrosion resistance and conductivity.
• Polyamide (PA46) insulating body provides structural stability.

Headers, Male Pins Applications

• General electronic interconnect systems requiring standard 2.54 mm spacing.
• Signal transmission in industrial control modules.
• Prototyping and development board connections.

Headers, Male Pins Procurement Notes

Verify the specific part number suffix 'Z' against official Fischer Elektronik documentation to confirm exact plating specifications and material composition. Ensure that the 31-position count matches the required circuit density. Cross-reference the datasheet for thermal ratings and current carrying capacity before finalizing procurement decisions to guarantee compatibility with the target application environment.

Headers, Male Pins Selection Notes

Select this component when a single-row, 31-pin male header with a 2.54 mm pitch is required. The choice depends on the need for through-hole mounting and square contact geometry. Consider the polyamide insulation and tin plating for environmental durability. Verify that the physical dimensions, including the 3.00 mm insertion depth, fit within the available PCB space constraints.

Headers, Male Pins Part Context

This component belongs to the SL 11 series of male headers produced by Fischer Elektronik. The series offers various contact counts ranging from one to thirty-six positions while maintaining a consistent 2.54 mm grid. The SL 11 139 31 Z represents a specific variant within this lineup, distinguished by its 31-pin configuration and standard through-hole termination style.

Headers, Male Pins Replacement Considerations

Consult Fischer Elektronik catalogs for alternative part numbers within the SL 11 series that match the 31-position requirement. Verify mechanical compatibility and electrical specifications before substituting with components from other manufacturers to ensure interface integrity.
