SL 1 025 21 S

Headers, Male Pins Overview

The SL 1 025 21 S is a board-to-board or wire-to-board connector header from the Fischer Elektronik SL 1 series. It features a 2.54 mm (0.100 inch) pitch with 21 positions in a single row. The component utilizes male pins with a square contact shape and a push-pull locking mechanism. Designed for surface mount installation, it employs solder termination. The contacts are constructed from copper-tin alloy, featuring gold plating on the mating interface and tin plating on the column. The housing is made of black polyamide (PA46), reinforced with glass fiber, ensuring UL94 V-0 flammability rating. Rated for 3A current and 250VAC voltage, it operates within a temperature range of -40°C to 163°C.

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, pitch, and mounting style. Ensure compatibility with automated surface mount placement equipment. Confirm that the gold plating thickness meets the required durability standards for the intended application environment. Cross-reference the UL94 V-0 rating with safety regulations applicable to the final product assembly.

Headers, Male Pins Selection Notes

Select this component when a single-row, surface-mount male header with a 2.54mm pitch is required. The 21-position configuration suits applications needing moderate I/O density. Consider the push-pull locking feature if vibration resistance is critical. Verify that the operating temperature range of -40°C to 163°C aligns with the environmental conditions of the deployment site.

Headers, Male Pins Part Context

This part belongs to the SL 1 series of PCB connectors manufactured by Fischer Elektronik GmbH & Co. KG. The series offers various configurations for board-to-board and wire-to-board connections. Components in this line typically utilize high-performance thermoplastics and precise metal stamping techniques to ensure consistent electrical performance and mechanical reliability across different industrial electronics applications.

Headers, Male Pins Replacement Considerations

Consult the official Fischer Elektronik catalog for direct substitutes within the SL 1 series with differing pin counts. Generic equivalents may match the 2.54mm pitch but often lack the specific push-pull locking mechanism and PA46 material properties. Verify dimensional compatibility before considering alternative manufacturers.
