RUMC23P7 Equivalent & Substitute Parts

Part Overview

The RUMC23P7 is a general purpose relay manufactured by Schneider Electric from the Harmony series. It is a socketable, plug-in DPDT (2 Form C) relay with a 230VAC coil, rated for 10A at 250VAC switching voltage. The relay features a lighted indicator and non-latching coil operation, designed for industrial control applications requiring reliable electromagnetic switching.

The RUMC23P7 maintains Active product status with 687 pieces in current inventory. Identifying equivalent substitute parts is necessary for supply chain continuity, design flexibility, and procurement optimization when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RUMC23P7 are identified based on strict electrical and mechanical parameter equivalence within the Harmony series relay family. The substitution criteria are based on the following key parameters:

Electrical Parameters:

• Coil voltage: 230VAC
• Contact form: DPDT (2 Form C)
• Contact rating: 10A
• Switching voltage: 250VAC, 28VDC maximum
• Coil current: 33.8 mA
• Coil resistance: 6.8 kOhms
• Must operate voltage: 184 VAC
• Must release voltage: 34.5 VAC
• Operate and release times: 20 ms each

Mechanical Parameters:

• Mounting type: Socketable
• Termination style: Plug In
• Contact material: Silver Nickel (AgNi)
• Operating temperature range: -40°C ~ 55°C

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The RUMC21P7 satisfies all specified electrical and mechanical requirements for direct substitution in applications requiring the RUMC23P7.

Parameter Comparison

Engineering Selection Recommendations

The RUMC21P7 is a direct parametric equivalent to the RUMC23P7 and functions as a complete substitute in all applications where the RUMC23P7 is specified. Both parts are manufactured by Schneider Electric within the Harmony series and share identical electrical and mechanical characteristics.

Compliance and Certification Status:

Both the RUMC23P7 and RUMC21P7 carry the same ECCN classification (EAR99) and HTSUS code (8536.49.0075). The RUMC21P7 additionally carries ROHS3 compliance certification, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status, indicating enhanced environmental and regulatory compliance documentation.

Inventory Considerations:

The RUMC21P7 maintains higher current inventory (900 pieces) compared to the RUMC23P7 (687 pieces), providing improved supply chain availability for procurement planning.

Selection Basis:

Component selection between these two equivalent parts should be based on:

• Immediate availability requirements
• Regulatory compliance documentation needs for the end application
• Existing inventory management protocols
• Supply chain continuity objectives

Both parts are suitable for direct substitution without circuit modification or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the RUMC21P7 be used as a direct replacement for the RUMC23P7 in existing designs?

A: Yes. The RUMC21P7 is a parametric equivalent with identical electrical and mechanical specifications. It operates at the same coil voltage (230VAC), contact rating (10A), switching voltage (250VAC/28VDC), and timing characteristics (20ms operate/release). Both parts use identical socketable, plug-in termination and are compatible with the same relay bases and sockets.

Q: Are there any differences in contact material or reliability between these parts?

A: No. Both parts use Silver Nickel (AgNi) contact material and operate across the same temperature range (-40°C to 55°C). Coil resistance, must-operate voltage, and must-release voltage specifications are identical.

Q: What is the significance of the ROHS3 compliance on the RUMC21P7?

A: ROHS3 compliance indicates the RUMC21P7 meets current European Union Restriction of Hazardous Substances directives. This certification is relevant for applications subject to EU environmental regulations or customer specifications requiring ROHS compliance documentation.

Q: Do these relays require the same socket or base for installation?

A: Yes. Both the RUMC23P7 and RUMC21P7 are socketable, plug-in relays within the Harmony series. They use identical mounting interfaces and are interchangeable in existing relay socket installations.

Q: What is the Moisture Sensitivity Level (MSL) rating and why does it matter?

A: The RUMC21P7 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This specification is relevant for supply chain logistics and storage environment requirements but does not affect operational performance compared to the RUMC23P7.

Q: Are both parts currently in active production?

A: Yes. Both the RUMC23P7 and RUMC21P7 maintain Active product status with Schneider Electric, ensuring continued availability and technical support.
