Key Parameters

Substitute Part Grouping Explanation

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

• Connector Type: Plug with female sockets
• Number of Positions: 2-position configuration
• Mounting Type: Free hanging (in-line) installation
• Orientation: Keyed design for polarization
• Fastening Mechanism: Connection method compatibility

The C90-3106F10SL-4S from Harwin Inc. qualifies as a substitute based on matching these core functional parameters. Both components are 2-position circular connector plugs with female sockets designed for free hanging installation with keyed orientation. The substitute maintains the same connector category and functional purpose while offering an active product status with current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The C90-3106F10SL-4S is designated as the manufacturer-recommended substitute for the obsolete RM12WBP-2S(71). Selection of this alternative is supported by:

• Product Status Alignment: The substitute is active and in current production, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS classifications, maintaining export and tariff compliance.
• Moisture Sensitivity: Both components carry MSL 1 (Unlimited) rating, indicating equivalent environmental handling requirements.
• Functional Compatibility: Matching connector type, position count, mounting configuration, and keyed orientation ensure functional interchangeability in applications designed for the original component.

Frequently Asked Questions (FAQ)

Q: What are the primary differences between RM12WBP-2S(71) and C90-3106F10SL-4S?

A: The main differences are shell size (12 versus 10SL-4), fastening type (bayonet lock versus threaded), and termination method (not specified versus solder cup). The substitute offers additional specifications including current rating (13A), voltage rating (500VAC, 700VDC), and operating temperature range (-55°C ~ 125°C).

Q: Can C90-3106F10SL-4S be used as a direct replacement in existing assemblies?

A: Mechanical and electrical compatibility must be verified at the system level. While both components share core functional parameters (2-position plug, female sockets, keyed orientation, free hanging mount), differences in shell size, fastening mechanism, and termination method require assessment against specific application requirements.

Q: What is the inventory status of these components?

A: RM12WBP-2S(71) has 1028 pieces in stock as new original inventory. C90-3106F10SL-4S has 3239 pieces in stock as new original inventory.

Q: Are there any compliance or certification differences?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications. The C90-3106F10SL-4S carries RoHS3 compliance and REACH unaffected status, providing additional regulatory documentation for applications requiring these certifications.

Q: What termination options are available?

A: The RM12WBP-2S(71) termination method is not specified in available documentation. The C90-3106F10SL-4S uses solder cup termination, which is suitable for direct soldering to PCB traces or wire connections.
