SL 20 THR 139 1 G

Headers, Male Pins Overview

The SL 20 THR 139 1 G is a single-row male pin header manufactured by Fischer Elektronik. It features a 2.54 mm pitch and utilizes through-hole soldering (THR) technology for secure PCB attachment. The connector contains one contact position with square-shaped pins made from CuSn alloy, finished with gold plating on the mating surface. Key dimensions include an overall contact length of 13.90 mm, a contact length to mate of 8.10 mm, a column length of 3.00 mm, and an insulation height of 2.80 mm.

Headers, Male Pins Feature Summary

• Utilizes through-hole soldering technique for robust mechanical connection
• Features gold-plated contacts for reliable signal transmission
• Designed with square contact shape for precise alignment

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board connections
• General electronic circuit assembly

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix 'G' confirms gold plating as distinct from other finish variants like 'S'. Ensure the single-position configuration matches the design requirements. Confirm the through-hole mounting style aligns with the target PCB layout and manufacturing process capabilities before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a single-point connection via through-hole mounting is required. The gold finish offers superior conductivity compared to tin-only options. Verify that the 2.54 mm pitch fits the existing footprint constraints. Consider the insulation height and overall profile for enclosure clearance compatibility during the design phase.

Headers, Male Pins Part Context

This part belongs to the SL 20 THR 139 series of male headers from Fischer Elektronik. The series is characterized by its 0.635 mm contact diameter and standard 2.54 mm spacing. Variants within the series differ primarily in contact count and surface finish, providing flexibility for various density and environmental requirements in electronic assemblies.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, single-row configuration, and through-hole mounting method. Verify that alternative manufacturers offer compatible gold-plated contacts and similar dimensional tolerances for the insulation height and contact length to ensure mechanical interchangeability.
