Engineering Selection Recommendations

The RPS0J561MCN1GS is the identified substitute for the obsolete PCR0J561MCL4GS. Both components are manufactured by Nichicon and maintain ROHS3 compliance and REACH unaffected status.

Electrical Compatibility: The substitute part maintains identical capacitance (560 µF), voltage rating (6.3 V), and tolerance (±20%), ensuring functional equivalence in circuit operation.

Physical Considerations: The RPS0J561MCN1GS has larger physical dimensions (0.315" diameter, 0.461" height) compared to the original part (0.248" diameter, 0.315" height). PCB layout modifications may be required to accommodate the increased footprint and land size (0.327" x 0.327" versus 0.260" x 0.260").

Performance Characteristics: The substitute exhibits lower ESR (14 mOhm versus 20 mOhm) and higher ripple current capacity at 100 kHz (4.4 A versus 1.8 A), providing improved performance in high-frequency applications. The substitute operates within a reduced temperature range (-55°C to 105°C versus -55°C to 125°C) with a lower lifetime rating (2000 Hrs @ 105°C versus 4000 Hrs @ 125°C).

Product Availability: The RPS0J561MCN1GS is currently in active production status with confirmed inventory availability, ensuring supply chain continuity for new designs and production runs.

Frequently Asked Questions (FAQ)

Q: Can the RPS0J561MCN1GS be used as a direct replacement for the PCR0J561MCL4GS?

A: The RPS0J561MCN1GS is electrically equivalent for general purpose applications. However, physical dimensions differ significantly. PCB layout modifications are necessary to accommodate the larger case size and land pattern.

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

A: Both parts share identical capacitance (560 µF), voltage rating (6.3 V), and tolerance (±20%). The substitute has lower ESR, higher ripple current capacity, and larger physical dimensions. The substitute operates at a lower maximum temperature (105°C versus 125°C) and has a reduced lifetime rating at elevated temperature.

Q: Are both parts RoHS compliant?

A: Yes, both the PCR0J561MCL4GS and RPS0J561MCN1GS are ROHS3 compliant and REACH unaffected.

Q: Will the substitute part fit the existing PCB footprint?

A: No. The RPS0J561MCN1GS requires a larger footprint. The land size increases from 0.260" x 0.260" to 0.327" x 0.327". PCB redesign is required for physical compatibility.

Q: Which part should be selected for new designs?

A: The RPS0J561MCN1GS should be selected for new designs due to its active production status and improved electrical performance characteristics. The PCR0J561MCL4GS is obsolete and no longer recommended for new applications.

Q: Are there temperature limitations I should consider?

A: The substitute part operates to a maximum of 105°C, compared to 125°C for the original part. Applications requiring sustained operation above 105°C require alternative component selection.
