Key Parameters

Substitute Part Grouping Explanation

Substitution of the RJ1V-C-D48 is determined by the following critical parameters:

• Coil Voltage: 48VDC (exact match required)
• Contact Form: SPDT (1 Form C) configuration (exact match required)
• Contact Rating: 12A minimum (equal or higher acceptable)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Voltage Operating Range: Must Operate Voltage ≥ 33.6 VDC and Must Release Voltage ≤ 4.8 VDC

The RC1V-C-D48 meets all substitution criteria as a direct equivalent. Both relays share identical coil voltage, contact configuration, current rating, mounting method, and termination style. The RC1V-C-D48 maintains compatible voltage operating parameters and is actively produced, providing a viable replacement for the Last Time Buy RJ1V-C-D48.

Parameter Comparison

Engineering Selection Recommendations

The RC1V-C-D48 is the direct substitute for the RJ1V-C-D48. Both relays are manufactured by IDEC and share identical electrical specifications for coil voltage, contact configuration, current rating, and voltage operating thresholds. The RC1V-C-D48 is currently in Active product status, ensuring continued availability and supply chain support.

The RC1V-C-D48 offers enhanced switching voltage capability (440VAC, 300VDC versus 250VAC, 125VDC), lower coil current draw (9 mA versus 11 mA), and an extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C). The RC1V-C-D48 is RoHS Compliant, meeting modern regulatory requirements. Release time is faster (5 ms versus 10 ms), which may provide performance benefits in time-sensitive switching applications.

Frequently Asked Questions (FAQ)

Q: Can the RC1V-C-D48 be used as a direct replacement for the RJ1V-C-D48?

A: Yes. Both relays share identical coil voltage (48VDC), contact form (SPDT), current rating (12A), mounting type (Through Hole), and termination style (PC Pin). Voltage operating parameters are compatible.

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

A: The RC1V-C-D48 has higher maximum switching voltage ratings, lower coil current consumption, faster release time, and a wider operating temperature range. The RC1V-C-D48 is RoHS Compliant and currently in Active production status.

Q: Does packaging differ between these parts?

A: Yes. The RJ1V-C-D48 is supplied in Bulk packaging, while the RC1V-C-D48 is supplied in Tube packaging. Both are through-hole mounted PCB relays with identical pin configurations.

Q: Are there any circuit design considerations when substituting the RC1V-C-D48 for the RJ1V-C-D48?

A: The coil resistance differs slightly (5.36 kOhms versus 4.34 kOhms), resulting in lower coil current draw in the RC1V-C-D48. Existing circuit designs will function with the RC1V-C-D48 without modification. The faster release time (5 ms) may improve switching performance in applications requiring rapid de-energization.

Q: Is the RC1V-C-D48 suitable for high-temperature applications?

A: The RC1V-C-D48 operates across -40°C ~ 85°C, providing a 15°C wider upper temperature limit compared to the RJ1V-C-D48 (-40°C ~ 70°C). This makes the RC1V-C-D48 suitable for applications requiring extended temperature performance.
