RUMC32F7 Equivalent & Substitute Parts

Part Overview

The RUMC32F7 is a general purpose relay manufactured by Schneider Electric from the Harmony series. It features a 3PDT (3 Form C) contact configuration with a 120VAC coil, rated for 10A at 250VAC switching voltage. The relay is socketable with plug-in termination, equipped with a lighted indicator and test button for field diagnostics. Product status is Active, ensuring continued availability and support. Substitute parts are identified when original inventory is unavailable or when equivalent electrical and mechanical specifications allow direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the RUMC32F7 is based on electrical and mechanical parameter equivalence within the Schneider Electric Harmony relay series. The substitute part RUMF32F7 qualifies as a direct equivalent based on the following criteria:

Electrical Equivalence Parameters:

• Identical coil voltage (120VAC) and coil current (70.6 mA)
• Identical contact form (3PDT / 3 Form C)
• Identical contact rating (10A at 250VAC, 28VDC maximum)
• Identical coil resistance (1.7 kOhms)
• Identical must-operate and must-release voltage thresholds (96VAC / 18VAC)
• Identical switching response times (20ms operate, 20ms release)

Mechanical Equivalence Parameters:

• Identical mounting type (Socketable)
• Identical termination style (Plug In)
• Identical operating temperature range (-40°C ~ 55°C)
• Identical contact material (Silver Nickel AgNi)

Compliance Equivalence:

• Both parts are ROHS3 Compliant
• Both parts are REACH Unaffected
• Both parts carry identical ECCN and HTSUS classifications

The primary difference between RUMC32F7 and RUMF32F7 is the termination connector type (cylindrical pin versus quick-connect), which does not affect electrical performance when used with compatible sockets.

Parameter Comparison

Engineering Selection Recommendations

Both RUMC32F7 and RUMF32F7 are Active products from Schneider Electric with full ROHS3 compliance and REACH compliance status. Selection between these parts should be based on socket compatibility within the installed base:

RUMC32F7 Selection Criteria:

• Use when cylindrical pin sockets are specified in the application
• Current inventory: 832 pieces

RUMF32F7 Selection Criteria:

• Use when quick-connect (QC) pin sockets are specified in the application
• Current inventory: 1126 pieces

Both relays deliver identical electrical performance and thermal characteristics. The choice between them is determined by the socket interface type already present in the control panel or equipment. No circuit modifications are required when substituting between these two part numbers, provided the socket type matches the relay termination style.

Frequently Asked Questions (FAQ)

Q: Can RUMF32F7 replace RUMC32F7 in an existing installation?

A: RUMF32F7 can replace RUMC32F7 only if the relay socket accommodates quick-connect (QC) pin termination. The electrical performance is identical, but the physical connector type must match the socket interface. If the socket is designed for cylindrical pins, RUMF32F7 will not fit.

Q: Are there any electrical performance differences between RUMC32F7 and RUMF32F7?

A: No. Both relays have identical coil voltage (120VAC), contact rating (10A at 250VAC), switching response times (20ms), and operating temperature range (-40°C to 55°C). The only difference is the termination connector type.

Q: What is the difference between cylindrical pin and quick-connect termination?

A: Cylindrical pin (CYL PIN) termination uses round pins that insert into corresponding sockets. Quick-connect (QC PIN) termination uses flat blade connectors. Both are plug-in styles, but they require different socket types. The choice is determined by the relay base or socket already installed in the equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both RUMC32F7 and RUMF32F7 are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations for electronic components.

Q: Can I use either part interchangeably in new designs?

A: Yes, for new designs, either part can be selected based on socket availability and design preference. Both are Active products with full manufacturer support. The selection should be based on the relay base or socket type specified for the application.

Q: What is the coil current draw for these relays?

A: Both relays draw 70.6 mA at 120VAC coil voltage, with a coil resistance of 1.7 kOhms. This specification is identical for both RUMC32F7 and RUMF32F7.
