SL 11 190 21 S

Headers, Male Pins Overview

The Fischer Elektronik SL 11 190 21 S is a single-row male pin header connector designed for through-hole mounting. It features 21 positions with a 0.100-inch (2.54 mm) pitch. The contacts are made of copper-tin alloy, plated with tin on the mating surface and column. The insulating material is polyamide (PA46), rated UL 94 V-0. The connector operates within a temperature range of -40°C to +163°C and withstands reflow soldering at 260°C for 10 seconds. Total contact length is 19.00 mm, with a mating contact length of 13.21 mm.

Headers, Male Pins Feature Summary

• Through-hole mounting for secure PCB attachment
• Single-row configuration with 21 positions
• Tin-plated copper-tin contacts for reliable conductivity
• Polyamide insulation with UL 94 V-0 flammability rating

Headers, Male Pins Applications

• General-purpose electronic circuit interconnections
• Industrial control panel wiring
• Consumer electronics assembly
• Test and measurement equipment connections

Headers, Male Pins Procurement Notes

Verify the specific suffix 'S' corresponds to the tin-plated variant as per official datasheets. Confirm that the 21-position count matches project requirements. Ensure compatibility with standard 2.54 mm pitch mating connectors. Check for RoHS compliance status if required by local regulations. Validate thermal resistance ratings against intended operating environments.

Headers, Male Pins Selection Notes

Choose this model when a single-row, 21-pin through-hole header is needed. The 2.54 mm pitch ensures broad compatibility with standard PCB footprints. Tin plating offers cost-effective conductivity suitable for non-corrosive environments. Consider the PA46 insulation for applications requiring moderate heat resistance up to 163°C. Verify mechanical stability needs against the single-row design constraints.

Headers, Male Pins Part Context

This component belongs to the SL 11 190 series of Fischer Elektronik headers. The series provides various position counts and plating options. The '190' designation typically indicates specific dimensional characteristics common to this family. Variants differ primarily in contact count and surface finish, such as gold or tin plating, to suit different environmental and electrical requirements.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 21-position count, 2.54 mm pitch, and through-hole mounting style. Verify identical contact plating (tin) and insulation material (PA46) for equivalent performance. Cross-reference with other manufacturers offering single-row male headers with similar thermal and mechanical specifications.
