Equivalents shown are the form-fit-function commercial designations of the same shell style, insert arrangement and contact gender. Amphenol PT and SOURIAU 851 designate both MIL class E and class F shells with the letter E; ITT Cannon KPT keeps the MIL class letter.
The MS3112E20-39PZ is a MIL-DTL-26482 Series I box mount receptacle carrying 39 size-20 pin contacts on the 20-39 insert arrangement. Series I uses solder-cup contacts and a quarter-turn bayonet latch, so the harness is terminated on the bench and mated quickly in the field. Typical applications include instrumentation looms, sensor breakouts, rail signalling jumpers, ground-support test equipment and military sub-assemblies where a compact, vibration-resistant circular interface is required. ITT Cannon (KPT), Amphenol (PT), SOURIAU (851) and Airoadcon all build to the same interface dimensions, so the part number is interchangeable across qualified sources.
