Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCR1V470MCL1GS is determined by the following critical parameters:

Capacitance value must remain 47 µF to maintain circuit functionality. Tolerance of ±20% is acceptable across all candidates. Voltage rating must equal or exceed 35 V to ensure safe operation under maximum circuit voltage conditions. The aluminum polymer type is required to match the original electrical characteristics and thermal performance profile. ESR, ripple current capability, and lifetime ratings are secondary selection criteria that depend on specific application requirements and thermal operating conditions.

The PCV1H470MCL1GS qualifies as a direct substitute based on matching capacitance, tolerance, and exceeding the voltage requirement at 50 V. Both parts are manufactured by Nichicon and share identical surface mount package geometry and mounting specifications.

Parameter Comparison

Engineering Selection Recommendations

The PCV1H470MCL1GS is suitable as a substitute for the obsolete PCR1V470MCL1GS in applications where the circuit voltage does not exceed 35 V. The substitute part provides higher voltage rating (50 V), lower ESR (30 mOhm versus 48 mOhm), and greater ripple current capability (2.2 A versus 1.1 A at 100 kHz).

The substitute part is classified as active product status, ensuring continued availability and supply chain stability. Both parts maintain ROHS3 compliance. The PCV1H470MCL1GS operates to a maximum temperature of 105°C compared to 125°C for the original part; circuit thermal conditions must be evaluated to confirm compatibility in high-temperature automotive applications.

Frequently Asked Questions (FAQ)

Can the PCV1H470MCL1GS replace the PCR1V470MCL1GS in all applications?

The PCV1H470MCL1GS is electrically compatible where circuit voltage remains at or below 35 V. The higher voltage rating of the substitute provides additional safety margin. Thermal operating conditions must be confirmed; the substitute part is rated to 105°C maximum versus 125°C for the original.

What are the physical package differences between these parts?

Both parts use identical surface mount radial can package geometry and mounting specifications. The PCV1H470MCL1GS has a larger physical size (0.394" diameter and height versus 0.248" diameter and 0.240" height for the original), requiring PCB layout verification before substitution.

Are there compliance or certification differences?

Both parts are ROHS3 compliant. The original PCR1V470MCL1GS carries AEC-Q200 automotive qualification; the PCV1H470MCL1GS does not list this certification. Applications requiring AEC-Q200 qualification must confirm acceptability with design authority.

What is the difference in ESR between these capacitors?

The PCV1H470MCL1GS has lower ESR at 30 mOhm compared to 48 mOhm for the PCR1V470MCL1GS. Lower ESR reduces heat generation and improves transient response in power supply filtering applications.

How do ripple current ratings affect selection?

The PCV1H470MCL1GS supports 2.2 A ripple current at 100 kHz versus 1.1 A for the original part. Higher ripple current capability allows operation in higher-frequency switching applications or circuits with greater AC current demands.
