It belongs to the standard-density DE-9 shell size (1/DE/E layout) — the most common footprint for serial RS-232 ports, instrumentation interfaces, and industrial control I/O. Gold-plated brass contacts handle the signal-level duty — rated 6A per contact at 125V. The 4-40 threaded inserts accept standard D-sub jack-screws for vibration-resistant mating. ## Mounting and Footprint The backset spacing is 0.318\" (8.08mm) — the distance from the PCB surface to the front of the connector shell. That dimension is what you check against the panel cutout clearance and the bracket thickness before committing the board layout. The 4-40 threaded inserts are integral to the housing — no separate hardware needed for the screw-lock. Mates with any standard D-sub receptacle that has a 4-40 female thread on the mating face. RoHS non-compliant — this part contains lead or other restricted substances above the 0.1% threshold per EU Directive 2011/65/EU. If the end equipment requires RoHS conformance, look at the RoHS-compliant variants in the AMPLIMITE HD-20 series (e.g., 8-1437045-3, which is packaged in bulk). The non-compliant status is a sourcing constraint for EU-market builds; a compliance waiver or exemption may apply. ## Sourcing and Cross-References The 8-1437045-3 is a bulk-packaged variant. Neither is a direct drop-in substitute for the 747250-4 — the tray packaging of the seed part is the distinguishing factor for automated assembly lines that expect tray-fed pick-and-place. For volume procurement, the RFQ should specify the tray packaging to avoid line-side repackaging costs.","metaTitle":"TE AMPLIMITE HD-20 747250-4 D-Sub Plug, 9 Pos, R/A","metaDescription":"TE AMPLIMITE HD-20 747250-4 D-Sub plug, 9 positions, right-angle solder, gold contacts, 6A, 125V.
