Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCR1A181MCL1GS is based on the following critical parameters:

• Capacitance Value: 180 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Package Type: Radial, Can - SMD (exact match required)
• Physical Dimensions: 0.248" Dia (6.30mm) with compatible height and land size
• Mounting Type: Surface Mount (exact match required)
• Dielectric Type: Aluminum Polymer (exact match required)

The PCG1A181MCL1GS meets all substitution criteria. Both parts share identical capacitance, voltage rating, package configuration, and physical footprint compatibility. Differences in ESR, lifetime rating, and operating temperature range reflect series-level design variations but do not preclude functional equivalence for the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The PCG1A181MCL1GS is the direct equivalent for the obsolete PCR1A181MCL1GS. Both components are ROHS3 compliant and manufactured by Nichicon with identical electrical specifications for capacitance, voltage rating, and tolerance.

The PCG1A181MCL1GS is currently in active production status, ensuring long-term availability and supply chain continuity. The PCR series is obsolete, making the PCG series the appropriate replacement path.

For applications requiring the automotive AEC-Q200 qualification of the original PCR1A181MCL1GS, design validation against the PCG series specifications is necessary, as the PCG series does not carry automotive ratings in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the PCG1A181MCL1GS be used as a direct replacement for the PCR1A181MCL1GS?

A: Yes. Both parts share identical capacitance (180 µF), voltage rating (10 V), tolerance (±20%), package type (Radial, Can - SMD), and physical footprint (0.248" Dia, 6.30mm). The PCG series is the active equivalent of the obsolete PCR series.

Q: What are the differences between these two parts?

A: The PCG1A181MCL1GS has lower ESR (25 mOhm vs. 34 mOhm) and higher ripple current capability (2.6 A vs. 1.4 A @ 100 kHz). The PCR series supports higher temperature operation (-55°C to 125°C) and longer lifetime rating (4000 Hrs @ 125°C) compared to the PCG series (-55°C to 105°C, 2000 Hrs @ 105°C).

Q: Are there any compliance differences?

A: Both parts are ROHS3 compliant. The original PCR1A181MCL1GS carries AEC-Q200 automotive qualification. The PCG1A181MCL1GS is designated for general purpose applications and does not include automotive ratings in the provided specifications.

Q: Will the PCG1A181MCL1GS fit the same PCB footprint?

A: Yes. Both parts have identical surface mount land size (0.260" L x 0.260" W, 6.60mm x 6.60mm) and compatible physical dimensions. The PCG height (0.236" max) is slightly lower than the PCR (0.240" max), which presents no compatibility issues.

Q: Which part should I select for new designs?

A: The PCG1A181MCL1GS is the recommended choice for new designs due to its active production status and improved electrical performance (lower ESR, higher ripple current). For applications requiring automotive qualification, alternative qualified components should be evaluated.
