SL 1 025 21 Z

Headers, Male Pins Overview

The SL 1 025 21 Z is a male pin header connector from the Fischer Elektronik SL 1 series, designed for through-hole mounting. It features 21 positions with a single row and a 2.54 mm (0.100 inch) pitch. The contacts are made of copper tin alloy with a nickel underplate and gold flash finish on the mating surface. The insulator is constructed from glass-fiber reinforced polyamide (PA46/nylon 4/6), rated UL94 V-0, in black color. Rated at 3A and 250VAC, it operates within a temperature range of -40°C to +163°C.

Headers, Male Pins Feature Summary

• Through-hole straight pin header configuration for reliable board-to-board or wire-to-board interconnections
• Gold-plated contact surfaces ensure stable electrical performance and corrosion resistance
• High-temperature resistant PA46 insulation material supports soldering processes up to 260°C
• UL94 V-0 flammability rating provides enhanced safety compliance for electronic assemblies

Headers, Male Pins Applications

• Industrial control systems requiring robust signal transmission
• Consumer electronics assembly with standard 2.54mm spacing requirements
• Test and measurement equipment interfaces
• Automotive electronics modules operating in high-temperature environments

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix matches the required contact count and plating thickness. Confirm that the through-hole termination style aligns with the target PCB fabrication capabilities. Ensure the operating temperature range meets the environmental specifications of the final application. Cross-reference the UL certification details if regulatory compliance is mandatory for the product line.

Headers, Male Pins Selection Notes

Select this component when a single-row, 21-position male header is required for permanent through-hole assembly. The 2.54 mm pitch is standard for general-purpose interconnects. Consider the 3A current rating and 250VAC voltage limit for circuit compatibility. The straight orientation suits vertical mounting scenarios where space constraints allow for standard profile height.

Headers, Male Pins Part Context

This part belongs to the Fischer Elektronik SL 1 series, which offers various configurations of male headers. The SL 1 025 designation indicates the series and pitch characteristics, while the numeric suffix specifies the contact count and variant details. This series is engineered for durability and consistent electrical connectivity in demanding electronic applications.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, 21 positions, and through-hole termination. Verify that alternative manufacturers provide equivalent gold plating thickness and PA46 insulation materials. Ensure the replacement part maintains the same UL94 V-0 rating and current/voltage ratings to guarantee functional interchangeability without redesign.
