| Manufacturer | Equivalent Part Number |
|---|---|
| Airoadcon | MS3111E8-4SW |

| ITT Cannon (KPT) | KPT01E8-4SW |
| SOURIAU (851) | 85101E8-4SW |
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 MS3111E8-4SW is a MIL-DTL-26482 Series I cable connecting receptacle carrying 4 size-20 socket contacts on the 8-4 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.
