Product Description
The D38999/20 wall-mount receptacle is used as the panel-side connector in threaded MIL-DTL-38999 Series III interconnect systems. Tradin Connect reviews the original part number, drawing or mating connector to match shell size, insert arrangement, contact style, keying, service class and finish. Matching contacts, backshells and protective caps can be quoted as one harness BOM. Final configuration and documentation are confirmed before quotation.
This listing describes a cross-reference and supply-support option, not a blanket certification claim. Final material, finish, insert arrangement, performance and applicable compliance documents are confirmed against the supplier drawing and the customer's application before quotation.
