PCS0G561MCL1GS Equivalent & Substitute Parts

Part Overview

The PCS0G561MCL1GS is a 560 µF, 4 V aluminum polymer capacitor manufactured by Nichicon in the PCS series. This surface mount radial can capacitor is designed for general purpose applications requiring low equivalent series resistance and extended operational life. The part is currently active in production with ROHS3 compliance and REACH affected status.

Substitute parts are necessary when the original PCS0G561MCL1GS becomes unavailable due to inventory constraints, supply chain disruptions, or end-of-life status. Alternative Nichicon polymer capacitors with identical electrical ratings and compatible mechanical specifications provide direct functional equivalence for circuit board assembly and rework operations.

Substitute Part Grouping Explanation

Substitution eligibility for the PCS0G561MCL1GS is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

Capacitance: 560 µF
Voltage Rating: 4 V
Tolerance: ±20%
Package Type: Radial, Can - SMD
Surface Mount Land Size: 0.327" L x 0.327" W (8.30mm x 8.30mm)
Operating Temperature Range: -55°C to 105°C
Mounting Type: Surface Mount

Variable Parameters (Allowed Differences):

ESR (Equivalent Series Resistance): 8 mOhm to 18 mOhm
Lifetime @ 105°C: 2000 Hrs to 5000 Hrs
Physical Height: 0.264" (6.70mm) to 0.472" (12.00mm)
Ripple Current Capacity: 3.6 A to 5.4 A @ 100 kHz
Series Designation: PCS, PCF, PCJ, RHA, RPA

All four substitute parts meet the mandatory matching criteria and are therefore electrically and mechanically compatible with the PCS0G561MCL1GS.

Engineering Selection Recommendations

All substitute parts are active products with ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards. Selection among the four equivalent options depends on specific circuit requirements:

PCS0G561MCL1GS (Original): Highest lifetime rating at 5000 hours @ 105°C with moderate ESR of 18 mOhm. Compact height of 0.276" (7.00mm) suits space-constrained layouts. Lowest ripple current capacity at 3.6 A @ 100 kHz.

PCF0G561MCL4GS: Intermediate ESR of 13 mOhm with increased ripple current handling at 4.52 A @ 100 kHz. Taller profile at 0.472" (12.00mm) requires board layout verification. Reduced lifetime to 2000 hours @ 105°C.

PCJ0G561MCL9GS: Lowest ESR at 9 mOhm with highest ripple current capacity at 5.2 A @ 100 kHz. Taller profile at 0.472" (12.00mm). Suitable for high-frequency, high-current applications. 2000-hour lifetime @ 105°C.

RHA0G561MCN1GS: Lowest ESR at 8 mOhm with compact height matching the original at 0.264" (6.70mm). REACH unaffected status. Ripple current capacity of 5 A @ 100 kHz. 2000-hour lifetime @ 105°C.

RPA0G561MCN1GS: Low ESR of 9 mOhm with highest ripple current capacity at 5.4 A @ 100 kHz. REACH unaffected status. Taller profile at 0.461" (11.70mm). 2000-hour lifetime @ 105°C.

Frequently Asked Questions (FAQ)

Q: Can PCJ0G561MCL9GS replace PCS0G561MCL1GS directly on the circuit board?

A: Yes. Both parts share identical capacitance (560 µF), voltage rating (4 V), tolerance (±20%), and surface mount land size (0.327" L x 0.327" W). The PCJ variant has a taller height of 0.472" (12.00mm) compared to 0.276" (7.00mm), requiring verification of available board clearance above the component.

Q: What is the difference between RHA0G561MCN1GS and RPA0G561MCN1GS?

A: Both parts have identical electrical ratings and REACH unaffected status. RHA0G561MCN1GS has a compact height of 0.264" (6.70mm) with 8 mOhm ESR and 5 A ripple current @ 100 kHz. RPA0G561MCN1GS is taller at 0.461" (11.70mm) with 9 mOhm ESR and higher ripple current capacity at 5.4 A @ 100 kHz.

Q: Does the lower ESR of substitute parts affect circuit performance?

A: Lower ESR values (8-9 mOhm in substitutes versus 18 mOhm in the original) reduce voltage drop and heat generation during high-frequency ripple current operation. This represents an improvement in electrical performance and is compatible with existing circuit designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All five parts, including the original PCS0G561MCL1GS and all four substitutes, carry ROHS3 compliance certification.

Q: Which substitute part has the longest operational lifetime?

A: The original PCS0G561MCL1GS has the longest rated lifetime at 5000 hours @ 105°C. All four substitute parts are rated for 2000 hours @ 105°C.

Q: Can I use RHA0G561MCN1GS in a space-constrained application?

A: Yes. RHA0G561MCN1GS has a height of 0.264" (6.70mm), which is the most compact among all options and matches the original PCS0G561MCL1GS height of 0.276" (7.00mm), making it suitable for tight board layouts.
