RM302615 General Purpose Relay 3PDT 10A 115VAC Equivalent & Substitute Parts

Part Overview

The RM302615 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, featuring a 3PDT (3 Form C) contact configuration with a 115VAC coil and 10A contact rating. This relay is designed for socketable mounting applications with plug-in, quick connect termination. The product is classified as obsolete, making identification of equivalent substitute parts necessary for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RM302615 is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Contact form configuration: 3PDT (3 Form C)
• Contact current rating: 10 A minimum
• Coil voltage class: 115VAC to 120VAC range
• Mounting type: Socketable
• Termination style: Plug-in compatible
• Coil type: Non-latching operation

The substitute part 55.33.8.120.0050 from Finder Relays, Inc. satisfies these core requirements with a 120VAC coil voltage, which operates within the acceptable voltage tolerance range for 115VAC applications. Both parts maintain 3PDT contact configuration, 10A contact rating, socketable mounting, and non-latching coil operation.

Parameter Comparison

Engineering Selection Recommendations

The 55.33.8.120.0050 from Finder Relays, Inc. is an active product substitute for the obsolete RM302615. Both relays maintain identical contact form (3PDT), contact rating (10A), and socketable mounting configuration. The coil voltage difference of 5VAC (115VAC versus 120VAC) falls within standard industrial tolerance ranges for AC voltage applications.

The substitute part provides enhanced compliance status with ROHS3 certification and REACH unaffected designation, compared to the main part's RoHS compliance. The substitute includes additional features such as a lighted indicator and test button, and supports multiple approval agencies including CE, CSA, cURus, VDE, and UKCA.

The substitute part demonstrates faster switching characteristics (9ms operate time versus 15ms, and 5ms release time versus 10ms) and an extended upper operating temperature limit (85°C versus 55°C). These performance improvements do not compromise compatibility with existing socketable mounting installations.

Frequently Asked Questions (FAQ)

Q: Can the 55.33.8.120.0050 directly replace the RM302615 in existing installations?

A: Yes. Both relays share identical contact form (3PDT), contact rating (10A), socketable mounting type, and plug-in termination. The 120VAC coil voltage of the substitute operates within acceptable tolerance for 115VAC applications.

Q: What are the key differences between these two relays?

A: The primary differences are coil voltage (115VAC versus 120VAC), contact material (Silver Cadmium Oxide versus Silver Nickel), switching speed (RM302615 operates at 15ms versus 55.33.8.120.0050 at 9ms), and product status (obsolete versus active). The substitute provides enhanced temperature range capability (-40°C to 85°C versus -45°C to 55°C).

Q: Are there packaging differences between the main part and substitute?

A: The RM302615 is specified with dash packaging, while the 55.33.8.120.0050 is supplied in bulk packaging. Both maintain socketable mounting and plug-in termination compatibility.

Q: Does the substitute part meet current compliance requirements?

A: Yes. The 55.33.8.120.0050 is ROHS3 compliant and REACH unaffected, providing current regulatory compliance. It holds multiple approval certifications including CE, CSA, cURus, VDE, and UKCA.

Q: What is the impact of the different coil resistance values?

A: The RM302615 has 2 kOhms coil resistance while the 55.33.8.120.0050 has 4.7 kOhms. This difference reflects the 5VAC voltage differential and does not affect functional compatibility in standard 115VAC/120VAC supply applications.

Q: Are the switching voltage ratings compatible?

A: The RM302615 supports 440VAC maximum switching voltage while the 55.33.8.120.0050 supports 400VAC maximum. For applications requiring switching voltages above 400VAC, the original part specifications must be maintained.
