SL 1 128 21 S

Headers, Male Pins Overview

The SL 1 128 21 S is a male pin header connector manufactured by Fischer Elektronik. It features a single row of 21 positions with a 0.100 inch (2.54 mm) pitch. Designed for through-hole mounting, the contacts are tin-plated copper alloy. The connector has an overall contact length of 0.547 inches (13.90 mm), with a mating contact length of 0.319 inches (8.10 mm). The insulation height is 0.110 inches (2.80 mm). The housing material is polyamide (PA46), rated UL 94 V-0. The operating temperature range is -40°C to +163°C.

Headers, Male Pins Feature Summary

• Single-row male pin configuration for reliable signal transmission
• Through-hole termination method ensures secure PCB attachment
• Polyamide insulation housing provides thermal stability and flame resistance

Headers, Male Pins Applications

• General-purpose electronic circuit interconnections
• PCB-to-PCB or PCB-to-wire harness connections
• Industrial control module interfaces

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'S' corresponds to tin plating as documented. Confirm the pin count matches the required 21-position layout. Ensure the through-hole package style aligns with the target PCB fabrication capabilities. Cross-reference the manufacturer part number directly with official Fischer Elektronik catalogs to avoid substitution errors.

Headers, Male Pins Selection Notes

Select this component when a single-row, 21-pin male header is required. The 2.54 mm pitch is standard for general electronics. Tin plating offers cost-effective conductivity. Verify that the 0.110 inch insulation height fits within the mechanical constraints of the assembly. Ensure the operating temperature range meets the environmental requirements of the application.

Headers, Male Pins Part Context

This part belongs to the SL 1 series of Fischer Elektronik headers. The series includes various pin counts and plating options. The SL 1 128 21 S specifically denotes the 21-position variant with tin-plated contacts. It is distinct from gold-plated versions like the SL 1 128 21 G. The numbering convention indicates the series, row, and pin configuration.

Headers, Male Pins Replacement Considerations

The SL 1 128 21 Z is a similar variant but may differ in plating specifications. Verify compatibility if substituting with other Fischer Elektronik SL 1 series parts. Ensure the replacement maintains the same 2.54 mm pitch and 21-pin count. Check datasheets for any changes in insulation material or thermal ratings.
