Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCF0G821MCL1GS is permissible with the PCJ0J821MCL1GS based on the following criteria:

Maintained Parameters (Substitution Basis):

• Capacitance: 820 µF (identical)
• Tolerance: ±20% (identical)
• ESR: 13 mOhm (identical)
• Lifetime: 2000 Hrs @ 105°C (identical)
• Operating Temperature Range: -55°C to 105°C (identical)
• Package Type: Radial, Can - SMD (identical)
• Surface Mount Land Size: 0.406" L x 0.406" W (10.30mm x 10.30mm) (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameters (Upgrade Characteristics):

• Voltage Rating: 4 V (main part) vs. 6.3 V (substitute)
• Height - Seated (Max): 0.394" (10.00mm) (main part) vs. 0.315" (8.00mm) (substitute)
• Ripple Current @ 100 kHz: 4.8 A (main part) vs. 4.5 A (substitute)

The PCJ0J821MCL1GS represents an upgrade path with higher voltage rating and reduced physical height while maintaining all critical electrical performance metrics.

Parameter Comparison

Engineering Selection Recommendations

Both the PCF0G821MCL1GS and PCJ0J821MCL1GS maintain Active product status with full ROHS3 compliance and REACH compliance status. The PCJ0J821MCL1GS provides higher voltage rating (6.3 V vs. 4 V) and reduced height (8.00mm vs. 10.00mm), making it suitable for applications requiring increased voltage margin or space-constrained PCB layouts. Selection between these parts depends on circuit voltage requirements and available board space. Both components maintain identical capacitance, tolerance, ESR, thermal lifetime, and operating temperature specifications, ensuring functional equivalence in applications designed for the 4 V rating or lower.

Frequently Asked Questions (FAQ)

Q: Can PCJ0J821MCL1GS replace PCF0G821MCL1GS in a 4 V circuit?

A: Yes. The PCJ0J821MCL1GS has a 6.3 V rating, which exceeds the 4 V requirement. Higher voltage-rated capacitors operate safely at lower voltages. All other electrical parameters (capacitance, ESR, lifetime) are identical.

Q: What is the physical height difference between these parts?

A: The PCF0G821MCL1GS has a maximum seated height of 0.394" (10.00mm), while the PCJ0J821MCL1GS is 0.315" (8.00mm). The substitute is 0.079" (2.00mm) shorter, which may be critical for space-constrained designs.

Q: Are the PCB land patterns compatible?

A: Yes. Both parts use identical surface mount land sizes of 0.406" L x 0.406" W (10.30mm x 10.30mm), ensuring direct PCB compatibility without layout modifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PCF0G821MCL1GS and PCJ0J821MCL1GS are ROHS3 compliant and REACH affected, meeting identical regulatory requirements.

Q: Is there a difference in ripple current handling?

A: The PCF0G821MCL1GS supports 4.8 A ripple current at 100 kHz, while the PCJ0J821MCL1GS supports 4.5 A at 100 kHz. For applications requiring maximum ripple current capacity, the main part specification should be verified.

Q: What is the ESR specification for both parts?

A: Both parts have identical ESR of 13 mOhm, ensuring equivalent performance in low-impedance applications.
