Substitute Part Grouping Explanation

Substitution of the PCF0J821MCL1GS is determined by strict equivalence in the following parameters:

• Capacitance: 820 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Aluminum Polymer (exact match required)
• Package Type: Radial, Can - SMD (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)

Substitute parts may vary in the following parameters while maintaining functional equivalence:

• ESR (Equivalent Series Resistance): 9–13 mOhm
• Lifetime @ 105°C: 2000–15000 Hrs
• Ripple Current @ 100 kHz: 4.5–5.8 A
• Physical Dimensions (Diameter and Height): Within SMD radial can form factor
• Surface Mount Land Size: Adjusted for dimensional variations
• Manufacturer: Nichicon or Chemi-Con
• Series Designation: PCF, PCJ, PCK, RHS, RPS, or NPCAP™-PXA

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain the core electrical specifications of 820 µF capacitance at 6.3 V with ±20% tolerance and aluminum polymer construction. Selection among substitutes should be based on the following criteria:

Dimensional Compatibility: The PCF0J821MCL1GS has a diameter of 10.00 mm and height of 12.70 mm with 10.30 mm x 10.30 mm land size. Substitutes with identical land sizes (PCJ0J821MCL1GS, PCK0J821MCO1GS, RPS0J821MCN1GS, APXA6R3ARA821MJC0G) provide direct footprint compatibility. Substitutes with 8.30 mm x 8.30 mm land sizes (PCJ0J821MCL4GS, PCJ0J821MCL6GS, RHS0J821MCN1GS) require PCB layout modification.

ESR Performance: The PCF0J821MCL1GS specifies 10 mOhm ESR. Substitutes with lower ESR (PCK0J821MCO1GS at 9 mOhm) provide improved performance. Substitutes with higher ESR (PCJ0J821MCL1GS at 13 mOhm, PCJ0J821MCL6GS at 12 mOhm, RPS0J821MCN1GS at 12 mOhm) may be acceptable depending on ripple current requirements.

Ripple Current Capability: The PCF0J821MCL1GS supports 5.8 A ripple current at 100 kHz. Applications requiring maximum ripple current capacity should prioritize APXA6R3ARA821MJC0G (5.5 A), RPS0J821MCN1GS (5.5 A), or PCJ0J821MCL4GS (5.15 A). Lower ripple current ratings (PCJ0J821MCL1GS at 4.5 A) are suitable for lower-stress applications.

Lifetime Rating: The PCF0J821MCL1GS specifies 2000 hours at 105°C. The APXA6R3ARA821MJC0G offers extended lifetime of 15000 hours at 105°C, suitable for applications requiring enhanced reliability. All other substitutes maintain the 2000-hour rating.

Compliance: All substitute parts are ROHS3 compliant. The APXA6R3ARA821MJC0G and RHS0J821MCN1GS carry REACH Unaffected status, while remaining parts are REACH Affected.

Frequently Asked Questions (FAQ)

Q: Can PCJ0J821MCL4GS replace PCF0J821MCL1GS directly on the PCB?

A: PCJ0J821MCL4GS has a different land size (8.30 mm x 8.30 mm versus 10.30 mm x 10.30 mm) and different physical dimensions (8.00 mm diameter, 12.00 mm height versus 10.00 mm diameter, 12.70 mm height). Direct PCB replacement is not possible without layout modification.

Q: What is the difference between Nichicon and Chemi-Con substitutes?

A: Both manufacturers produce 820 µF, 6.3 V aluminum polymer capacitors meeting the same electrical specifications. The APXA6R3ARA821MJC0G from Chemi-Con offers extended lifetime (15000 hours versus 2000 hours) and REACH Unaffected status. Physical dimensions and land sizes differ slightly.

Q: Does lower ESR always mean better performance?

A: Lower ESR reduces heat generation and improves transient response in high-frequency applications. However, substitution is valid across the 9–13 mOhm ESR range provided by the listed parts. Selection depends on specific circuit requirements for ripple current handling and thermal management.

Q: Are all substitutes rated for the same temperature range?

A: Yes. All listed substitute parts operate across -55°C to 105°C, matching the PCF0J821MCL1GS specification.

Q: Which substitute offers the best long-term reliability?

A: The APXA6R3ARA821MJC0G provides 15000 hours lifetime at 105°C compared to 2000 hours for all other parts, offering superior long-term reliability for applications requiring extended service life.

Q: Can I use a substitute with higher ripple current rating in a lower-stress application?

A: Yes. Substitutes with higher ripple current ratings are backward compatible with applications requiring lower ripple current. The electrical and thermal performance will remain within specification.
