SL 1 154 21 S

Headers, Male Pins Overview

The SL 1 154 21 S is a single-row pin header connector manufactured by Fischer Elektronik. It features a 0.635 mm (0.025 inch) contact pitch and accommodates 21 positions. The component utilizes through-hole termination for secure PCB mounting. Contact surfaces are finished with tin plating to ensure reliable electrical connections. The housing is constructed from polyamide, providing structural integrity and insulation.

Headers, Male Pins Feature Summary

• Single-row configuration designed for compact board-to-board or wire-to-board interconnections
• Precision 0.635 mm pitch ensures accurate alignment with mating connectors
• Through-hole termination method provides robust mechanical stability on printed circuit boards

Headers, Male Pins Applications

• Interconnecting daughterboards to main logic boards in modular electronic systems
• Wire-to-board connections for sensor modules and peripheral devices
• Prototype development requiring precise low-profile signal routing

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact plating material and insulation color. Ensure the selected variant matches the required 0.635 mm pitch and 21-position count for your design. Cross-reference the RoHS compliance status with the latest regulatory documentation before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a fine-pitch 0.635 mm header is required for space-constrained applications. Compare the total height and mating length against available clearance on the target assembly. Confirm that the tin-plated contacts meet the environmental requirements of the intended operating conditions and mating cycle expectations.

Headers, Male Pins Part Context

This part belongs to the SL 1 series of Fischer Elektronik pin headers. The series offers various row counts and contact numbers to support diverse connectivity needs. The SL 1 designation indicates a single-row arrangement, distinguishing it from multi-row stackable alternatives within the broader product portfolio.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 0.635 mm pitch and 21-contact configuration. Verify that alternative components match the through-hole termination style and compatible housing dimensions. Check for equivalent tin plating thickness if corrosion resistance is critical for the application environment.
