20-position, 2.54 mm pitch right-angle shrouded header
The 5-103166-8 is a 20-position, dual-row, right-angle header from the AMPMODU Mod II series. The 4-wall shroud guides the mating receptacle squarely onto the pins, preventing bent contacts during blind or automated assembly. Rated 3 A per contact at 25°C, with the temperature rise limited by the UL94 V-0 thermoplastic housing. The 30 µinch gold plating on the mating face supports 500+ mating cycles — in a field-service cabinet where the connector is cycled quarterly, that is well over a century of service life at the contact interface.
Operating range and deployment context
The -65°C to 105°C operating temperature covers outdoor telecom cabinets, industrial control panels, and engine compartments — the phosphor bronze contacts and thermoplastic housing stay within their rated envelope across the band. The 0.135" (3.43 mm) post length suits standard through-hole soldering on 1.6 mm boards. Tin-plated posts (100 µinch) provide a reliable solder joint; the gold mating finish handles the signal path without fretting corrosion over repeated insertions.
Lifecycle and sourcing
RoHS compliant per the manufacturer listing.
