RUMF22JD General Purpose Relay Equivalent & Substitute Parts

Part Overview

The RUMF22JD is an active general purpose relay manufactured by Schneider Electric within the Harmony series. This DPDT (2 Form C) relay features a 12VDC coil, 10A contact rating at 250VAC, and socketable mounting with plug-in termination. The relay includes a lighted indicator and test button for operational verification.

Finding equivalent and substitute parts is necessary when the RUMF22JD reaches end-of-life status, when inventory constraints occur, or when alternative packaging configurations better suit specific application requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RUMF22JD are determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• Coil voltage: 12VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 10 A at 250VAC
• Maximum switching voltage: 250VAC, 28VDC
• Maximum switching load: 2500VA, 280W
• Coil current: 100 mA
• Coil type: Non Latching
• Mounting type: Socketable
• Termination style: Plug In
• Operating temperature range: -40°C ~ 55°C
• Contact material: Silver Nickel (AgNi)
• Approval agencies: CSA, EAC, UL

Variations in packaging configuration, inventory status, or RoHS compliance do not affect substitutability when all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both RUMF22JD and RUMC22JD are active products within the Schneider Electric Harmony series and carry identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Product Status: Both parts maintain active status, ensuring continued availability and support from the manufacturer.

Compliance and Certifications: Both parts hold CSA, EAC, and UL approvals, meeting the same regulatory requirements across North American, European, and international markets.

Packaging Configuration: RUMF22JD is supplied in standard packaging, while RUMC22JD is supplied in box packaging. Packaging selection depends on inventory management practices and storage requirements.

RoHS Compliance: RUMC22JD is explicitly ROHS3 compliant. When RoHS3 compliance is a project requirement, RUMC22JD is the appropriate selection.

Inventory Availability: RUMF22JD has 856 pieces in stock; RUMC22JD has 891 pieces in stock. Selection may depend on immediate availability needs.

Both parts are electrically and mechanically interchangeable for all applications requiring a 12VDC DPDT general purpose relay with 10A contact rating and socketable mounting.

Frequently Asked Questions (FAQ)

Q: Can RUMC22JD replace RUMF22JD in existing applications?

A: Yes. RUMC22JD is a direct electrical and mechanical equivalent. All coil voltage, contact ratings, switching characteristics, operating temperature range, and termination specifications are identical. The relay will function identically in the same circuit configuration.

Q: What is the difference between RUMF22JD and RUMC22JD?

A: The primary differences are packaging configuration (standard versus box) and RoHS compliance status. RUMC22JD is ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Are both relays socketable?
