Equivalent & Substitute Parts for Amphenol ICC (FCI) 51732-008 Backplane Connector

Part Overview

The Amphenol ICC (FCI) 51732-008 is an obsolete backplane connector from the PwrBlade® series, designed as a right-angle, board edge, male header with 42 positions (28 signal and 14 power) and a 0.100" (2.54mm) pitch. Its configuration supports both signal and blade power connections, with mating guides, gold or GXT™ contact finishes, UL94 V-0 flammability rating, and an operating temperature range of -20°C to 105°C. Due to the product's obsolete status, sourcing alternatives is necessary for continued manufacturing, repair, or design-in processes.
