Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCS1C820MCL9GS is determined by strict equivalence in the following parameters:

• Capacitance value: 82 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Aluminum Polymer (exact match required)
• Package: Radial, Can - SMD (exact match required)
• Mounting: Surface Mount (exact match required)

Variations permitted within substitute parts include ESR, lifetime rating at 105°C, ripple current specifications, and physical dimensions, provided the substitute maintains mechanical compatibility with the PCB land pattern and thermal requirements of the application. All substitute parts listed maintain RoHS3 compliance and are actively produced.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and RoHS3 compliance. Selection between the PCS1C820MCL9GS and its substitutes depends on application-specific requirements:

PCF1C820MCL1GS and PCS1C820MCL9GS share identical ESR (28 mOhm) and physical dimensions (8.00 mm diameter, 7.00 mm height), with the primary difference being lifetime rating. The PCS1C820MCL9GS offers extended 5000-hour lifetime at 105°C compared to PCF1C820MCL1GS at 2000 hours.

PCG1C820MCL1GS presents a smaller footprint (6.30 mm diameter, 6.00 mm height) with slightly elevated ESR (30 mOhm) and reduced ripple current capability (2.3 A @ 100 kHz). This option is suitable for space-constrained designs where thermal performance is not critical.

RPS1C820MCN1GS maintains the 8.00 mm diameter but with reduced height (6.70 mm) and higher ESR (40 mOhm). Ripple current is limited to 2.3 A @ 100 kHz.

APXE160ARA820MF80G, manufactured by Chemi-Con, offers the lowest ESR (24 mOhm) with a 6.30 mm diameter footprint and 7.70 mm height. This part is suitable for applications requiring superior low-impedance performance.

Frequently Asked Questions (FAQ)

Q: Can PCG1C820MCL1GS be used as a direct replacement for PCS1C820MCL9GS?

A: PCG1C820MCL1GS is electrically equivalent in capacitance, voltage, and tolerance. However, it features a smaller physical footprint (6.30 mm vs. 8.00 mm diameter) and reduced ripple current capability (2.3 A vs. 2.8 A @ 100 kHz). Substitution is valid only if the PCB land pattern accommodates the smaller dimensions and the application does not require the higher ripple current specification.

Q: What is the significance of ESR differences among substitute parts?

A: ESR directly affects thermal performance and high-frequency impedance. The PCS1C820MCL9GS has 28 mOhm ESR. APXE160ARA820MF80G offers lower ESR (24 mOhm), beneficial for noise-sensitive applications. RPS1C820MCN1GS has higher ESR (40 mOhm), which may increase heat generation under high ripple current conditions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including PCS1C820MCL9GS, PCF1C820MCL1GS, PCG1C820MCL1GS, RPS1C820MCN1GS, and APXE160ARA820MF80G, are RoHS3 compliant.

Q: How does lifetime rating affect part selection?

A: PCS1C820MCL9GS is rated for 5000 hours at 105°C, while all substitute parts are rated for 2000 hours at 105°C. For applications requiring extended operational life at elevated temperatures, PCS1C820MCL9GS is the appropriate choice. For general purpose applications with standard thermal profiles, the 2000-hour rating is sufficient.

Q: Can APXE160ARA820MF80G replace PCS1C820MCL9GS in all applications?

A: APXE160ARA820MF80G is electrically compatible with equivalent capacitance, voltage, and tolerance. The lower ESR (24 mOhm) is advantageous for noise reduction. However, the different physical dimensions (6.30 mm diameter, 7.70 mm height vs. 8.00 mm diameter, 7.00 mm height) require PCB land pattern verification before substitution.

Q: What is the difference between Nichicon and Chemi-Con parts in this list?

A: All parts meet the same electrical specifications for capacitance, voltage, and tolerance. Chemi-Con's APXE160ARA820MF80G offers superior ESR performance (24 mOhm). Selection between manufacturers depends on supply availability, qualification requirements, and application-specific performance needs.
