RFS1C220MCN1GS Equivalent & Substitute Parts

Part Overview

The RFS1C220MCN1GS is a 22 µF, 16 V aluminum polymer capacitor manufactured by Nichicon in the FPCAP/RFS series. This surface mount radial can capacitor is designed for general purpose applications requiring stable capacitance and low equivalent series resistance. The part is currently active in production with 1790 units in stock. Substitute parts may be required due to supply chain constraints, manufacturing discontinuation, or design optimization needs while maintaining electrical and mechanical compatibility.

The PCF1C220MCL1GS meets all electrical and mechanical parameters required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the RFS1C220MCN1GS and PCF1C220MCL1GS are active production parts from Nichicon with identical electrical specifications and mechanical dimensions. Selection between these parts may be based on inventory availability, supply chain logistics, or design documentation requirements. The RFS1C220MCN1GS is currently available with 1790 units in stock, while the PCF1C220MCL1GS has 2167 units available. Both parts are ROHS3 compliant and suitable for applications requiring 22 µF capacitance at 16 V with low ESR characteristics.

Frequently Asked Questions (FAQ)

Q: Can PCF1C220MCL1GS be used as a direct replacement for RFS1C220MCN1GS?

A: Yes. Both parts are manufactured by Nichicon and share identical electrical parameters (22 µF, 16 V, ±20%, 45 mOhm ESR, 2000 Hrs @ 105°C) and mechanical dimensions (5.00 mm diameter, 6.00 mm height, 5.30 mm × 5.30 mm land size). They are pin-compatible surface mount components.

Q: Are there differences in compliance or certifications between these parts?

A: Both parts are ROHS3 compliant. The RFS1C220MCN1GS is REACH Unaffected, while the PCF1C220MCL1GS is REACH Affected. Both carry the same ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: What is the difference between the RFS and PCF series designations?

A: The RFS and PCF designations indicate different product series within Nichicon's aluminum polymer capacitor portfolio. Both series meet the specified electrical and mechanical requirements for this application.

Q: Will the PCB layout require modification if switching between these parts?

A: No. Both parts have identical case dimensions and land sizes (5.30 mm × 5.30 mm), so no PCB layout changes are necessary.

Q: Are the ripple current ratings identical?

A: The RFS1C220MCN1GS specifies ripple current at both low frequency (121 mA @ 120 Hz) and high frequency (1.21 A @ 100 kHz). The PCF1C220MCL1GS specifies ripple current at high frequency (1.21 A @ 100 kHz). Both parts support the same high frequency ripple current rating.
