RJ22V-C-D24 Equivalent & Substitute Parts

Part Overview

The RJ22V-C-D24 is a general purpose relay manufactured by IDEC, featuring DPDT (2 Form C) contact configuration with 24VDC coil voltage and 1A contact rating. This through-hole mounted relay is designed for PC pin termination and offers sealed flux protection. The product is currently in Last Time Buy status, making identification of compatible substitute parts essential for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJ22V-C-D24 is determined by strict equivalence across the following critical parameters:

• Coil voltage: 24VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Contact rating: 1 A (exact match required)
• Coil current: 22.1 mA (exact match required)
• Coil resistance: 1.08 kOhms (exact match required)
• Must operate voltage: 16.8 VDC (exact match required)
• Must release voltage: 2.4 VDC (exact match required)
• Operating temperature range: -40°C ~ 70°C (exact match required)
• Series: RJ (same product family)

The RJ22S-C-D24 meets all critical electrical parameters and belongs to the same RJ series. The primary difference is the mounting configuration: the RJ22V-C-D24 uses through-hole PC pin termination, while the RJ22S-C-D24 uses socketable plug-in termination. This distinction affects board integration but does not alter electrical performance or functional compatibility when proper socket accommodation is available.

Parameter Comparison

Engineering Selection Recommendations

The RJ22S-C-D24 is the manufacturer-recommended substitute for the RJ22V-C-D24. Both parts maintain identical electrical specifications across coil voltage, contact configuration, current ratings, timing parameters, and operating temperature range. The RJ22S-C-D24 is currently in Active product status, ensuring continued availability and support.

The primary consideration for selection is mounting accommodation. The RJ22V-C-D24 requires through-hole PC pin footprints on the PCB, while the RJ22S-C-D24 requires a compatible relay socket. If the application board supports socketable relay mounting, the RJ22S-C-D24 provides superior long-term supply chain continuity due to its Active status.

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The RJ22S-C-D24 contact material specification (Silver Nickel only) differs from the RJ22V-C-D24 (Silver Nickel and Gold), but this does not affect functional equivalence for standard switching applications within the specified voltage and current ratings.

Frequently Asked Questions (FAQ)

Q: Can the RJ22S-C-D24 directly replace the RJ22V-C-D24 on an existing PCB?

A: Direct PCB replacement is not possible without board modification. The RJ22V-C-D24 uses PC pin through-hole termination, while the RJ22S-C-D24 requires a relay socket. If the board design includes a compatible relay socket footprint, the RJ22S-C-D24 can be used. Otherwise, the board layout must be redesigned to accommodate the socketable configuration.

Q: Are the electrical specifications identical between these two parts?

A: The critical electrical specifications are identical: 24VDC coil voltage, DPDT contact form, 1A contact rating, 22.1mA coil current, 1.08kOhms coil resistance, and -40°C to 70°C operating temperature. The switching voltage specification differs (RJ22V-C-D24: 250VAC/125VDC max; RJ22S-C-D24: 250VAC/30VDC max), which may be relevant for high-voltage DC applications.

Q: Why is the RJ22V-C-D24 in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The RJ22S-C-D24 remains in Active status and represents the current product offering from IDEC for this relay specification.

Q: What is the difference in contact material between these parts?

A: The RJ22V-C-D24 specifies Silver Nickel and Gold contact material, while the RJ22S-C-D24 specifies Silver Nickel only. Both materials are suitable for the specified 1A switching current and voltage ratings.

Q: Are both parts compliant with current regulatory standards?

A: Both the RJ22V-C-D24 and RJ22S-C-D24 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
