10158

Overview

SparkFun Electronics part number 10158 is a set of long breakaway male pin headers designed for through-hole mounting. The connector features 40 positions with a standard 2.54mm (0.100 inch) pitch. These headers are engineered to facilitate easy logic shifting between devices by allowing socket-to-socket usage. The design includes a plastic separator that can be slid up or down, enabling users to accommodate specific spacing needs during assembly.

Feature Summary

• Long 20mm header length allows for socket-to-socket connectivity
• Sliding plastic separator accommodates variable spacing requirements
• Through-hole mounting style for secure board attachment

Applications

• Interfacing between development boards and peripheral modules
• Prototyping circuits requiring adjustable vertical spacing
• Creating custom cable connections between stacked hardware layers

Procurement Notes

Verify the exact quantity per package before ordering, as manufacturers may supply these headers in varying counts such as strips or individual sets. Confirm that the 2.1mm or 2.54mm pitch matches your target socket specifications. Ensure the through-hole footprint on your PCB aligns with the 40-position layout. Check for any specific mechanical constraints regarding the sliding separator mechanism if tight clearances are involved in your enclosure design.

Selection Notes

Select this component when standard height headers are insufficient for connecting two sockets directly. The extended 20mm length provides necessary clearance for stacked connectors or thick cables. Consider the mechanical stability provided by the through-hole pins versus surface mount alternatives. Evaluate whether the sliding separator feature offers sufficient flexibility for your specific assembly workflow compared to fixed-length alternatives.

Part Context

This component belongs to SparkFun's accessories line, specifically categorized under headers and male pins. It serves as a fundamental passive interconnect element within their ecosystem of development boards and sensors. Unlike active components, it provides physical and electrical continuity without signal processing capabilities, acting as a bridge between different electronic subsystems.

Replacement Considerations

Generic 40-position, 2.54mm pitch male headers may serve as substitutes if the specific long length and sliding separator are not critical. Verify that replacement parts maintain the same through-hole pin diameter and overall height to ensure compatibility with existing sockets.
