Engineering Selection Recommendations

The RC2V-A-D48 is the recommended substitute for the RJ2V-A-D48. Selection is based on the following factors:

• Functional Equivalence: The RC2V-A-D48 maintains identical coil voltage, contact configuration, and current rating specifications.
• Production Status: The RC2V-A-D48 is in Active production, ensuring long-term component availability and supply chain continuity.
• Enhanced Electrical Performance: The substitute part supports higher maximum switching voltages (440VAC, 300VDC versus 250VAC, 125VDC), providing greater application flexibility.
• Improved Operating Range: Extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C) accommodates broader environmental conditions.
• Compliance: The RC2V-A-D48 is RoHS Compliant with MSL rating of 1 (Unlimited), meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the RC2V-A-D48 directly replace the RJ2V-A-D48 in existing designs?

A: Yes. Both relays share identical coil voltage (48VDC), contact form (DPST-NO), current rating (8A), mounting type (through-hole), and termination style (PC pin). The RC2V-A-D48 is electrically and mechanically compatible for direct substitution.

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

A: The RC2V-A-D48 offers higher maximum switching voltages, lower coil current draw (9 mA versus 11 mA), faster release time (5 ms versus 10 ms), and an extended operating temperature range. Contact material composition differs, with the RC2V-A-D48 using Silver Tin Oxide and Gold versus Silver Nickel in the RJ2V-A-D48.

Q: Does the higher coil resistance of the RC2V-A-D48 affect circuit design?

A: The RC2V-A-D48 has a coil resistance of 5.76 kOhms compared to 4.34 kOhms in the RJ2V-A-D48. This difference results in lower coil current (9 mA versus 11 mA) at the same 48VDC supply voltage. Circuit designs must account for this resistance change when calculating drive circuit requirements.

Q: Are there packaging differences between these parts?

A: The RJ2V-A-D48 is supplied in standard packaging, while the RC2V-A-D48 is packaged in Tube format. Both use through-hole PC pin termination suitable for PCB mounting.

Q: What certifications apply to the RC2V-A-D48?

A: The RC2V-A-D48 is RoHS Compliant with an ECCN classification of EAR99 and HTSUS code 8536.41.0020. The original RJ2V-A-D48 carries CE, CSA, UR, and VDE approvals.
