RJ2V-A-D5 Equivalent & Substitute Parts

Part Overview

The RJ2V-A-D5 is a general purpose relay manufactured by IDEC, featuring a DPDT (2 Form C) contact configuration with 5VDC coil voltage and 8A contact rating. This through-hole mounted relay is designed for PCB applications requiring dual-pole, dual-throw switching capability. The product is currently in Last Time Buy status, making identification of equivalent substitute parts essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJ2V-A-D5 is evaluated based on the following critical parameters:

• Coil Voltage: Must be 5VDC to maintain circuit compatibility
• Mounting Type: Must be Through Hole to ensure PCB footprint compatibility
• Termination Style: Must be PC Pin for direct board connection
• Contact Rating: Must support minimum 8A switching capacity
• Coil Type: Must be Non Latching for equivalent operational behavior
• Switching Voltage: Must meet or exceed 250VAC, 125VDC maximum ratings

The RC2V-A-D5 qualifies as a manufacturer-recommended substitute. While it differs in contact form (DPST-NO vs. DPDT), it maintains all critical electrical and mechanical parameters required for functional equivalence in applications where the reduced contact configuration is acceptable.

Engineering Selection Recommendations

The RC2V-A-D5 is designated as the manufacturer-recommended substitute for the RJ2V-A-D5. Selection between these parts should be based on the following engineering criteria:

Choose RC2V-A-D5 when:

• The application requires an active product with ongoing manufacturer support
• Lower coil current (81 mA vs. 106 mA) provides design advantages
• Extended operating temperature range (-40°C ~ 85°C) is required
• Higher switching voltage capability (440VAC, 300VDC) is beneficial
• Faster release time (5 ms vs. 10 ms) is acceptable or preferred
• Contact form can be reduced from DPDT to DPST-NO

Retain RJ2V-A-D5 when:

• DPDT (2 Form C) contact configuration is functionally required
• Existing inventory supports current production needs
• Application-specific testing has been completed on this exact model

The RC2V-A-D5 carries ROHS3 compliance and REACH Unaffected status, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can RC2V-A-D5 directly replace RJ2V-A-D5 in all applications?

A: Direct replacement is possible only when the application does not require DPDT functionality. The RC2V-A-D5 provides DPST-NO (2 Form A) contact configuration, which is a reduced form. Verify circuit requirements before substitution.

Q: What is the difference between DPDT and DPST-NO contact forms?

A: DPDT (2 Form C) provides two independent switches, each with changeover capability (common, normally open, normally closed). DPST-NO (2 Form A) provides two independent switches, each with only normally open contacts. Applications requiring changeover or normally closed contacts cannot use DPST-NO configuration.

Q: Are the coil voltage and current specifications compatible?

A: Both relays operate on 5VDC coil voltage. The RC2V-A-D5 draws lower coil current (81 mA vs. 106 mA), which may reduce power supply loading. Both are compatible with standard 5VDC control circuits.

Q: What packaging differences exist between these parts?

A: RJ2V-A-D5 is supplied in Bulk packaging, while RC2V-A-D5 is supplied in Tube packaging. Packaging does not affect electrical or mechanical compatibility; it affects only procurement and handling procedures.

Q: Why does RC2V-A-D5 have higher switching voltage ratings?

A: The RC2V-A-D5 features enhanced contact materials (Silver Tin Oxide with Gold plating) compared to Silver Nickel in the RJ2V-A-D5, enabling higher voltage and current switching capability. This provides additional design margin for applications approaching voltage limits.

Q: Is the operating temperature range difference significant?

A: The RC2V-A-D5 supports -40°C ~ 85°C versus -40°C ~ 70°C for RJ2V-A-D5. The extended upper temperature limit provides additional margin for applications in elevated ambient conditions or high-density PCB environments.
