Key Parameters

Substitute Part Grouping Explanation

Substitution of the RM12WBP-2P(71) is based on the following critical parameters that must align between the main part and substitute components:

• Connector Type: Both must be plug connectors with male pins
• Number of Positions: Both must accommodate 2-position configurations
• Mounting Type: Both must support free hanging (in-line) installation
• Orientation: Both must feature keyed orientation for polarized mating
• Fastening Mechanism: Compatibility with connection and disconnection requirements
• Regulatory Compliance: ECCN and HTSUS classifications must remain consistent

The C90-3106F10SL-4P from Harwin Inc. satisfies these substitution criteria as an active product with equivalent functional positioning and mounting characteristics.
