PCR2A220MCL1GS Equivalent & Substitute Parts

Part Overview

The PCR2A220MCL1GS is a 22 µF, 100 V aluminum polymer capacitor manufactured by Nichicon in a radial, can-style surface mount package. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design support and procurement continuity. The part operates across a temperature range of -55°C to 125°C with a rated lifetime of 4000 hours at 125°C, making it suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Substitute Part Grouping Explanation

Substitution of the PCR2A220MCL1GS is determined by the following critical parameters:

Capacitance Value: Must remain 22 µF (±20% tolerance acceptable)
Voltage Rating: Substitute must meet or exceed 100 V rated voltage
Package Type: Must be Radial, Can - SMD with compatible surface mount land size (0.406" L x 0.406" W)
Mounting Type: Surface mount compatibility required
Material Type: Aluminum polymer construction
Physical Compatibility: Diameter and height must accommodate existing PCB layouts

The PCV1K220MCL1GS qualifies as a substitute based on matching capacitance (22 µF), identical package footprint, and compatible mounting specifications. However, the substitute operates at a reduced voltage rating (80 V versus 100 V) and exhibits different thermal performance characteristics.

Engineering Selection Recommendations

The PCV1K220MCL1GS is available as an active product from Nichicon, providing procurement continuity for the obsolete PCR2A220MCL1GS. Both parts maintain ROHS3 compliance and share identical surface mount land sizes, enabling direct PCB layout compatibility.

Selection of the PCV1K220MCL1GS requires circuit-level evaluation of the reduced voltage rating (80 V versus 100 V). Applications operating at or near the original 100 V specification must confirm that the 80 V rating provides adequate safety margin for the intended operating conditions. The substitute exhibits superior ripple current handling (2.2 A versus 1.6 A at 100 kHz) and marginally lower ESR (38 mOhm versus 39 mOhm), offsetting the reduced thermal lifetime rating.

The increased seated height (0.500" versus 0.394") of the substitute requires verification of available PCB clearance in the target application. REACH compliance status differs between the two parts; applications subject to REACH regulations must account for the affected status of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the PCV1K220MCL1GS directly replace the PCR2A220MCL1GS in all applications?

A: Direct replacement is possible only in applications where the circuit voltage does not exceed 80 V. The reduced voltage rating of the substitute requires circuit-level confirmation that adequate safety margin exists for the intended operating conditions.

Q: What is the impact of the increased seated height on PCB layout?

A: The PCV1K220MCL1GS has a maximum seated height of 0.500" (12.70 mm) compared to 0.394" (10.00 mm) for the original part. PCB designs must verify that clearance exists above the component location to accommodate the additional 0.106" (2.70 mm) height.

Q: Are the surface mount land sizes identical between the two parts?

A: Yes. Both the PCR2A220MCL1GS and PCV1K220MCL1GS use identical surface mount land sizes of 0.406" L x 0.406" W (10.30 mm x 10.30 mm), enabling direct footprint compatibility.

Q: How do the thermal performance characteristics compare?

A: The original part provides 4000 hours lifetime at 125°C, while the substitute provides 3000 hours at 105°C. Applications requiring extended operation at elevated temperatures should evaluate whether the reduced thermal rating of the substitute meets design requirements.

Q: What is the significance of the REACH compliance difference?

A: The PCR2A220MCL1GS is REACH Unaffected, while the PCV1K220MCL1GS is REACH Affected. Applications subject to REACH regulations must ensure that the affected status of the substitute complies with applicable regulatory requirements.

Q: Does the superior ripple current rating of the substitute provide any advantage?

A: The PCV1K220MCL1GS supports 2.2 A ripple current at 100 kHz compared to 1.6 A for the original part. This higher ripple current capability may provide additional design margin in high-frequency switching applications, though the reduced voltage rating remains the primary substitution constraint.
