Substitute Part Grouping Explanation

Substitution eligibility for the PCR1A331MCL1GS is determined by the following critical parameters:

Capacitance value: 330 µF (exact match required)
Voltage rating: 10 V (exact match required)
Package type: Radial, Can - SMD (exact match required)
Physical dimensions: 0.315" Dia (8.00 mm), Height 0.276" (7.00 mm) (exact match required)
Surface mount land size: 0.327" L x 0.327" W (8.30 mm x 8.30 mm) (exact match required)
Aluminum polymer type (exact match required)
Tolerance: ±20% (exact match required)

The PCG1A331MCL1GS meets all critical substitution parameters. Both parts share identical capacitance, voltage rating, physical dimensions, land size, tolerance, and package configuration. Differences in ESR, lifetime rating, ripple current capability, and operating temperature range reflect design variations between the PCR and PCG series but do not preclude functional substitution in applications where the PCG1A331MCL1GS electrical characteristics are acceptable.

Engineering Selection Recommendations

The PCG1A331MCL1GS is an active production substitute for the obsolete PCR1A331MCL1GS. Both parts are ROHS3 compliant and manufactured by Nichicon. The PCG1A331MCL1GS provides superior ESR performance (23 mOhm versus 28 mOhm) and higher ripple current capability (3.1 A versus 1.6 A at 100 kHz), making it suitable for applications where the PCR1A331MCL1GS was previously specified.

The PCG1A331MCL1GS operates within a reduced temperature range (-55°C ~ 105°C versus -55°C ~ 125°C) and has a lower lifetime rating (2000 Hrs @ 105°C versus 4000 Hrs @ 125°C). Applications requiring sustained operation above 105°C or extended lifetime at 125°C must evaluate whether the PCG series characteristics meet design requirements.

Both parts share identical physical dimensions, land size, and mounting configuration, enabling direct PCB layout compatibility. The PCG1A331MCL1GS is available in Tape & Reel packaging, whereas the PCR1A331MCL1GS was supplied in Cut Tape format.

Frequently Asked Questions (FAQ)

Q: Can the PCG1A331MCL1GS be used as a direct replacement for the PCR1A331MCL1GS?

A: Yes, from a physical and electrical standpoint. Both parts have identical capacitance (330 µF), voltage rating (10 V), tolerance (±20%), package type (Radial, Can - SMD), and physical dimensions (0.315" Dia, 0.276" height, 8.30 mm x 8.30 mm land size). PCB layout and mounting are directly compatible.

Q: What are the key differences between these parts?

A: The PCG1A331MCL1GS has lower ESR (23 mOhm versus 28 mOhm), higher ripple current capability (3.1 A versus 1.6 A at 100 kHz), a reduced maximum operating temperature (105°C versus 125°C), and a lower lifetime rating at elevated temperature (2000 Hrs @ 105°C versus 4000 Hrs @ 125°C).

Q: Is the PCG1A331MCL1GS suitable for automotive applications?

A: The PCG1A331MCL1GS is classified for general purpose applications and does not carry AEC-Q200 automotive qualification. The original PCR1A331MCL1GS was AEC-Q200 rated. Applications requiring automotive-grade components must evaluate whether general purpose classification is acceptable for the intended use.

Q: What is the impact of the reduced operating temperature range?

A: The PCG1A331MCL1GS maximum operating temperature is 105°C, compared to 125°C for the PCR1A331MCL1GS. Applications operating continuously at temperatures above 105°C must assess whether this limitation affects system performance or reliability.

Q: Are there packaging differences?

A: Yes. The PCR1A331MCL1GS was supplied in Cut Tape (CT) packaging, while the PCG1A331MCL1GS is supplied in Tape & Reel (TR) format. This affects procurement and assembly processes but does not impact component functionality.

Q: Do both parts meet RoHS compliance?

A: Yes, both the PCR1A331MCL1GS and PCG1A331MCL1GS are ROHS3 compliant.
