SL 11 112 21 G

Headers, Male Pins Overview

The SL 11 112 21 G is a male pin header connector manufactured by Fischer Elektronik. It features a single row with 21 contacts and a pitch of 0.100 inches (2.54 mm). The connector utilizes copper-tin alloy contacts with gold plating, ensuring low contact resistance of ≤5 mΩ. Rated for 3 A current and 250 V AC voltage, it offers a dielectric withstand voltage of 2000 V. The housing is made of PA 4.6 nylon with UL 94 V-0 flammability rating. Total contact length is 11.20 mm, with an insulation height of 2.80 mm. It supports through-hole soldering.

Headers, Male Pins Feature Summary

• Gold-plated CuSn alloy contacts ensure reliable electrical connection with low resistance
• PA 4.6 insulating material provides high thermal stability and UL 94 V-0 flame retardancy
• Single-row straight design facilitates standard through-hole PCB mounting

Headers, Male Pins Applications

• General-purpose board-to-board interconnections
• Wire-to-board connections in electronic assemblies
• Industrial control panel wiring interfaces

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'G' corresponds to the gold-plated contact finish as defined in the official Fischer Elektronik datasheet. Confirm that the 21-position count matches the required circuit density. Ensure the through-hole termination style aligns with the target PCB fabrication capabilities. Cross-reference the PA 4.6 insulation material specification against environmental operating requirements.

Headers, Male Pins Selection Notes

Select this component when a single-row male header with gold-plated contacts is required for robust signal integrity. The 2.54 mm pitch is suitable for standard commercial and industrial PCB layouts. Consider the 3 A current rating and 2000 V dielectric strength for appropriate safety margins. Verify that the straight orientation fits within the mechanical envelope constraints of the final assembly.

Headers, Male Pins Part Context

This part belongs to the SL 11 series of male pin headers from Fischer Elektronik. The series offers various contact counts and plating options. The '21 G' designation specifically indicates 21 positions with gold plating. This series is designed for general electronic applications requiring reliable through-hole connectivity.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Fischer Elektronik headers from the SL 11 series with matching pitch and contact count, such as SL 11 112 21 S if silver plating is acceptable. External manufacturers offering 2.54 mm pitch, 21-position, single-row male headers with similar current and voltage ratings may serve as alternatives, provided mechanical dimensions are verified.
