The socket mounts through a PCB with a hole diameter of 0.062\" and supports board thicknesses from 0.031\" to 0.125\". Solder termination secures the connection, and the no-tail design keeps the overall length at 0.290\" – a compact profile for tight board stacks. The socket depth of 0.148\" to 0.260\" accommodates varying pin lengths from the mating header. ## Sourcing an Obsolete Part Availability is lot-specific – submit an RFQ for current sourcing status. This socket mates with header pins in the 0.028\" to 0.033\" diameter range – typical for TE Series 3 headers. The solder termination and 0.062\" mounting hole diameter mean it fits standard through-hole PCB layouts. Confirm the mating header's pin diameter and board thickness before committing the BOM line.","metaTitle":"1-645986-2 TE Connectivity AMP Connectors Series 3 Pin","metaDescription":"1-645986-2 TE Connectivity Series 3 pin socket, tin-plated beryllium copper, accepts 0.028\"–0.033\" pins.
