Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RJ22V-C-D48 must maintain electrical and functional equivalence based on the following critical parameters:

• Coil voltage: 48VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 1 A minimum
• Switching voltage: 250VAC, 125VDC maximum capability
• Coil current: 11 mA
• Coil resistance: 4.34 kOhms
• Operating temperature range: -40°C ~ 70°C
• Series compatibility: RJ series

The RJ22S-C-D48 qualifies as a substitute based on identical electrical specifications. The primary difference is the mounting and termination method: the RJ22S-C-D48 uses socketable mounting with plug-in termination, whereas the RJ22V-C-D48 uses through-hole mounting with PC pin termination. This distinction allows for application-specific selection based on PCB design requirements.

Parameter Comparison

Engineering Selection Recommendations

The RJ22V-C-D48 is designated Last Time Buy, making the identification of active alternatives critical for ongoing production and design updates. The RJ22S-C-D48 is the direct electrical equivalent, currently in Active product status with higher inventory availability (1185 pcs vs. 712 pcs).

Selection between these parts depends on PCB design architecture:

• Retain RJ22V-C-D48 for existing through-hole PCB designs with PC pin termination requirements
• Transition to RJ22S-C-D48 for new designs or PCB revisions that can accommodate socketable relay mounting with plug-in termination

Both parts maintain identical electrical performance across all critical operating parameters, ensuring functional interchangeability within their respective mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the RJ22S-C-D48 directly replace the RJ22V-C-D48 on existing PCBs?

A: Direct PCB replacement is not possible without design modification. The RJ22V-C-D48 requires through-hole PC pin footprints, while the RJ22S-C-D48 requires socketable relay base footprints. PCB layout redesign is necessary for substitution.

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

A: Yes. Both parts share identical coil voltage (48VDC), contact form (DPDT), contact rating (1 A), switching voltage (250VAC/125VDC), coil current (11 mA), coil resistance (4.34 kOhms), and operating temperature range (-40°C ~ 70°C).

Q: Why is the RJ22V-C-D48 designated Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. Existing inventory is available for final orders, but no future production is planned. Transition to active alternatives is recommended for long-term supply security.

Q: What is the inventory status for each part?

A: RJ22V-C-D48 has 712 pcs in stock (Last Time Buy). RJ22S-C-D48 has 1185 pcs in stock (Active status), providing greater availability for new designs.

Q: Are there any differences in contact material or seal rating?

A: Both parts use identical contact material (Silver Nickel and Gold). The RJ22V-C-D48 specifies Sealed - Flux Protection; the RJ22S-C-D48 does not specify a seal rating in the provided data.
