PCR1C221MCL4GS Equivalent & Substitute Parts

Part Overview

The PCR1C221MCL4GS is a 220 µF, 16 V aluminum polymer capacitor manufactured by Nichicon in the PCR series. This component is designed for surface mount applications requiring low equivalent series resistance (ESR) and extended operational life at elevated temperatures. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCR1C221MCL4GS is determined by the following critical parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 16 V (minimum acceptable)
• Type: Aluminum polymer (maintains electrical characteristics)
• Mounting type: Surface mount (physical compatibility)
• Package: Radial, Can - SMD (footprint compatibility)
• Tolerance: ±20% (functional equivalence)

The PCV1C221MCL6GS meets all primary substitution criteria. While secondary parameters such as ESR, ripple current rating, and lifetime specifications differ, these variations remain within acceptable ranges for equivalent component selection in the aluminum polymer capacitor category.

Parameter Comparison

Engineering Selection Recommendations

The PCV1C221MCL6GS is the designated equivalent for the obsolete PCR1C221MCL4GS. Both components are manufactured by Nichicon and share identical core electrical specifications: 220 µF capacitance, 16 V voltage rating, ±20% tolerance, and aluminum polymer construction.

The PCV1C221MCL6GS maintains active product status, ensuring long-term availability and supply chain continuity. Both parts comply with ROHS3 standards and carry EAR99 ECCN classification.

Design considerations for substitution:

The PCV1C221MCL6GS exhibits a maximum operating temperature of 105°C compared to the PCR1C221MCL4GS at 125°C. Applications requiring sustained operation above 105°C require thermal analysis to confirm compatibility.

The ESR specification increases from 23 mOhm to 27 mOhm. In high-frequency ripple current applications, this 4 mOhm differential may impact thermal performance. The PCV1C221MCL6GS compensates with a higher ripple current rating of 2.0 A versus 1.7 A at 100 kHz.

Frequently Asked Questions (FAQ)

Q: Can the PCV1C221MCL6GS directly replace the PCR1C221MCL4GS in existing designs?

A: Yes. Both components share identical capacitance (220 µF), voltage rating (16 V), tolerance (±20%), and surface mount package specifications. Footprint compatibility is confirmed through matching Radial, Can - SMD package designation.

Q: What are the thermal operating differences between these parts?

A: The PCR1C221MCL4GS operates from -55°C to 125°C with 4000 hours lifetime at 125°C. The PCV1C221MCL6GS operates from -55°C to 105°C with 3000 hours lifetime at 105°C. Applications requiring sustained operation above 105°C should evaluate thermal requirements against the reduced maximum temperature specification.

Q: How do ESR and ripple current specifications compare?

A: The PCR1C221MCL4GS specifies 23 mOhm ESR with 1.7 A ripple current at 100 kHz. The PCV1C221MCL6GS specifies 27 mOhm ESR with 2.0 A ripple current at 100 kHz. The higher ripple current rating of the substitute part offsets the modest ESR increase for most general-purpose applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the PCR1C221MCL4GS and PCV1C221MCL6GS are ROHS3 compliant. The PCV1C221MCL6GS is REACH affected, while the PCR1C221MCL4GS is REACH unaffected.

Q: Why is the PCR1C221MCL4GS obsolete?

A: The PCR series has been superseded by the PCV series within Nichicon's product portfolio. The PCV1C221MCL6GS represents the active equivalent offering improved availability and supply chain support.
