Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RUMF32FD are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain identical:

• Coil Voltage: 110VDC (exact match required)
• Contact Form: 3PDT (3 Form C) (exact match required)
• Contact Rating (Current): 10 A (exact match required)
• Switching Voltage: 250VAC, 28VDC - Max (exact match required)
• Coil Current: 15.1 mA (exact match required)
• Coil Type: Non Latching (exact match required)
• Termination Style: Plug In (exact match required)
• Mounting Type: Socketable (exact match required)
• Operating Temperature Range: -40°C ~ 55°C (exact match required)
• Contact Material: Silver Nickel (AgNi) (exact match required)
• Coil Resistance: 7.3 kOhms (exact match required)

The RUMC32FD meets all substitution criteria and is classified as a parametric equivalent within the Harmony series.

Parameter Comparison

Engineering Selection Recommendations

Both RUMF32FD and RUMC32FD are Active status products within the Schneider Electric Harmony series. Selection between these parts is based on the following engineering criteria:

RUMF32FD is the primary specification part with established inventory of 928 pieces.

RUMC32FD is a parametric equivalent substitute with higher current inventory of 1052 pieces and additional compliance documentation including RoHS3 compliance and REACH unaffected status. The RUMC32FD is suitable for applications requiring enhanced environmental compliance documentation.

Both parts maintain identical electrical performance, mechanical compatibility, and operational characteristics. Socket compatibility and plug-in termination are preserved across both models, enabling direct substitution in socketable relay applications.

Frequently Asked Questions (FAQ)

Q: Can RUMC32FD replace RUMF32FD in existing applications?

A: Yes. The RUMC32FD is a parametric equivalent with identical coil voltage (110VDC), contact form (3PDT), current rating (10A), switching voltage (250VAC, 28VDC), coil current (15.1 mA), termination style (Plug In), and mounting type (Socketable). Both parts are socketable and plug-in compatible.

Q: What are the critical parameters that determine substitutability?

A: Substitutability is determined by exact equivalence in coil voltage, contact form, contact current rating, switching voltage, coil current, coil type, termination style, mounting type, operating temperature range, contact material, and coil resistance. All these parameters are identical between RUMF32FD and RUMC32FD.

Q: Are there differences in compliance or certifications?

A: Both parts carry CSA, EAC, and UL approvals. The RUMC32FD includes additional documentation for RoHS3 compliance and REACH unaffected status. These represent enhanced compliance documentation rather than functional differences.

Q: What is the inventory status for each part?

A: RUMF32FD has 928 pieces in stock. RUMC32FD has 1052 pieces in stock. Both are available as new original components.

Q: Are the operating characteristics identical?

A: Yes. Both parts operate at 88 VDC must-operate voltage, 11 VDC must-release voltage, 20 ms operate time, and 20 ms release time across the -40°C to 55°C operating temperature range.
