SL 1 128 25 Z

Headers, Male Pins Overview

The SL 1 128 25 Z is a male pin header connector manufactured by Fischer Elektronik. It features a single row with 25 positions and a 0.100 inch (2.54 mm) pitch. Designed for through-hole PCB mounting, the contact length measures 0.319 inches (8.10 mm) for mating and 0.118 inches (3.00 mm) for the column. The total contact length is 0.547 inches (13.90 mm), with an insulation height of 0.110 inches (2.80 mm). The contacts are square-shaped pins made of copper-tin alloy, finished with tin plating at a thickness of 157.5 µin (4.00 µm).

Headers, Male Pins Feature Summary

• Through-hole mounting configuration ensures secure mechanical attachment to printed circuit boards.
• Square contact shape provides stable mating interface with corresponding socket connectors.

Headers, Male Pins Applications

• General-purpose electronic equipment interconnection
• Industrial control system signal routing
• Consumer electronics board-to-board connections

Headers, Male Pins Procurement Notes

Verify the exact part number SL 1 128 25 Z against manufacturer datasheets to confirm pin count, pitch, and termination type. Ensure compatibility with mating connectors regarding contact geometry and current ratings. Check RoHS compliance status if required for specific regulatory environments. Confirm package quantity and handling instructions from official distributor documentation before ordering.

Headers, Male Pins Selection Notes

Select this component when a 25-position, single-row male header with 2.54 mm pitch is required for through-hole applications. Consider the copper-tin contact material and tin plating for standard conductivity and corrosion resistance. Evaluate thermal limits (-40°C to +163°C) against operational environment requirements. Compare physical dimensions (21.4 mm x 5.8 mm x 12.8 mm) with available PCB space constraints.

Headers, Male Pins Part Context

This component belongs to the Fischer Elektronik SL series of PCB connectors. The SL series offers various configurations for male and female headers, including different pin counts and contact finishes. This specific model represents a standard through-hole male pin variant within that product family.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 25-pin count, 2.54 mm pitch, through-hole termination, and male pin type. Verify identical physical dimensions and contact material specifications to ensure mechanical and electrical compatibility without redesigning the PCB footprint or mating interface.
