Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCR0J181MCL1GS is determined by the following critical parameters:

• Capacitance value: 180 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.197" Dia (5.00mm) and land size 0.209" L x 0.209" W (5.30mm x 5.30mm) (exact match required)
• Mounting type: Surface Mount (exact match required)

The PCG0J181MCL1GS meets all mandatory substitution criteria. Both parts share identical capacitance, voltage rating, tolerance, package configuration, and PCB land pattern compatibility. Differences in ESR, lifetime rating, and maximum operating temperature are secondary performance characteristics that do not prevent functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The PCG0J181MCL1GS is a direct substitute for the obsolete PCR0J181MCL1GS based on matching electrical and mechanical specifications. Both parts are ROHS3 compliant and manufactured by Nichicon, ensuring regulatory alignment and supply chain continuity.

The PCG0J181MCL1GS is currently in active production status, providing reliable availability for new designs and production replenishment. The substitute part exhibits lower ESR (33 mOhm versus 55 mOhm) and higher ripple current capability (1.9 A versus 900 mA at 100 kHz), representing performance improvements over the original specification.

The maximum operating temperature of the substitute is 105°C compared to 125°C for the original part. This difference is relevant only in applications requiring sustained operation above 105°C. For applications operating within the -55°C to 105°C range, the PCG0J181MCL1GS provides equivalent or superior performance.

Frequently Asked Questions (FAQ)

Q: Can the PCG0J181MCL1GS be used as a direct replacement for the PCR0J181MCL1GS?

A: Yes. Both parts share identical capacitance (180 µF), voltage rating (6.3 V), tolerance (±20%), package type (Radial, Can - SMD), physical dimensions (0.197" Dia), and PCB land pattern (0.209" L x 0.209" W). No circuit modifications or PCB layout changes are required.

Q: What are the physical compatibility considerations?

A: The PCG0J181MCL1GS has a maximum seated height of 0.236" (6.00mm) compared to 0.240" (6.10mm) for the PCR0J181MCL1GS. This 0.004" difference is negligible for standard PCB assembly and does not affect component placement or clearance in typical applications.

Q: Are there performance differences between these parts?

A: The PCG0J181MCL1GS exhibits lower ESR (33 mOhm versus 55 mOhm) and higher ripple current rating (1.9 A versus 900 mA at 100 kHz). These represent performance improvements. The maximum operating temperature is 105°C for the substitute versus 125°C for the original part.

Q: Which part should be selected for new designs?

A: The PCG0J181MCL1GS should be selected for new designs. It is in active production status, ensuring long-term availability and supply chain stability. The original PCR0J181MCL1GS is obsolete and should not be specified for new applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the PCR0J181MCL1GS and PCG0J181MCL1GS are ROHS3 compliant, meeting current environmental and regulatory requirements.
