Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MS3111F8-2S are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type: Receptacle configuration with female sockets
• Number of Positions: 2-position interface
• Shell Size - Insert: 8-2 specification
• Category: Circular Connectors
• Termination Method: Solder termination capability
• Fastening Type: Bayonet Lock mechanism
• Electrical Ratings: Current and voltage handling capacity
• Operating Temperature Range: -55°C to 125°C environmental tolerance
• Application Domain: Military-grade specifications

The MSW01E8-2S-SR qualifies as a substitute based on alignment across these core parameters, enabling direct functional replacement in applications where the MS3111F8-2S is specified.
