What it is and where it sits in the series
The Amphenol ICC DEV2V2P500G30LF is the 2-position power member of the DW D-Sub Combo series, sized 2V2 under the DE (Size 1) shell envelope. It is a right-angle through-hole plug carrying female power sockets alongside a mating-face male pin — the Combo designation means it accepts both contact types within the standard D-Sub shell form factor. Rated 30 A per circuit at 300 V with gold-over-brass contacts, it sits at the higher-current end of the DW power variants. The nickel-plated steel shell and UL94 V-0 thermoplastic body cover an operating range of -55 to 125 °C, which puts it in play for industrial power-conversion enclosures and DC bus bar interconnects where the board-level D-Sub form factor is already specified.
What the ratings mean for your board
The 0.458 inch backset defines how far the connector body sits behind the mounting face — the board layout must clear that depth plus the solder tail extension on the secondary side. Board locks and mounting brackets on the flange face lock the housing to the PCB during wave solder, so no spring-tab retention is needed; the layout pad pattern follows the four bracket holes in addition to the two signal/power through-hole positions. The 30 A rating on two dedicated power contacts is the primary selection driver — this is a power-class D-Sub, not a signal-density member. The 300 V rating covers most low-voltage industrial bus rails. The gold contact finish over brass gives lower contact resistance than tin at first mate and better resistance to fretting on any reconnect cycle, though the connector has no published mating-cycle figure — if reconnect duty drives the choice, that parameter needs to come from the Amphenol ICC DW series drawing directly. The 4-40 female screwlock flange accepts standard UNC 4-40 hardware on the mating side — this is the panel-attach feature, not a board-mounting element. Grounding indents in the flange mate with the connector face on the receptacle to bleed common-mode current before it reaches the signal contacts, which is standard practice for D-Sub shields in industrial I/O, but it means the front panel must provide a conductive face or bare-metal boss at the connector opening for the indent to seat against.
Sourcing and compliance
The DEV2V2P500G30LF is listed Active with RoHS Compliant status — no end-of-life notice or last-time-buy date listed. The series is a well-established Amphenol ICC product line with broad second-source coverage. No official successor or cross-reference is on record for this specific MPN.
