PCR2A180MCL1GS Equivalent & Substitute Parts

Part Overview

The PCR2A180MCL1GS is an 18 µF, 100 V aluminum polymer capacitor manufactured by Nichicon in a surface mount radial can package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part is designed for general purpose applications requiring stable capacitance and low equivalent series resistance in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCR2A180MCL1GS is determined by the following critical parameters:

• Capacitance Value: Must be 18 µF (±20% tolerance acceptable)
• Voltage Rating: Must be 100 V or higher
• Dielectric Type: Aluminum polymer construction required
• Package Configuration: Surface mount radial can format
• Mounting Compatibility: Surface mount technology (SMD)
• Electrical Performance: ESR and ripple current ratings must support the application requirements
• Environmental Compliance: RoHS3 compliance required for regulatory alignment

The PCV2A180MCL1GS meets these substitution criteria while offering improved availability as an active product.

Parameter Comparison

Engineering Selection Recommendations

The PCV2A180MCL1GS is a valid substitute for the obsolete PCR2A180MCL1GS based on matching electrical specifications and compliance certifications. Both parts are ROHS3 compliant and manufactured by Nichicon with identical capacitance, voltage rating, and tolerance values.

Key considerations for selection:

• Product Availability: The PCV2A180MCL1GS is an active product with current manufacturing status, ensuring long-term procurement viability compared to the obsolete PCR2A180MCL1GS.
• Physical Footprint: The substitute part has a larger case diameter (10.00 mm vs. 8.00 mm) and increased land size (10.30 x 10.30 mm vs. 8.30 x 8.30 mm). PCB layout modifications may be required.
• Temperature Rating: The main part supports operation to 125°C, while the substitute is rated to 105°C. Applications requiring the full temperature range of the original part must account for this limitation.
• Electrical Performance: The substitute offers lower ESR (41 mOhm vs. 42 mOhm) and higher ripple current capability (2.1 A vs. 1.5 A at 100 kHz), providing improved performance margins.

Frequently Asked Questions (FAQ)

Q: Can the PCV2A180MCL1GS be used as a direct replacement for the PCR2A180MCL1GS?

A: The PCV2A180MCL1GS is electrically compatible as a substitute. However, the larger physical dimensions require PCB layout verification to confirm the footprint accommodates the increased case diameter and land size.

Q: What is the primary difference between these two parts?

A: The main differences are product status (obsolete vs. active), physical package size, maximum operating temperature (125°C vs. 105°C), and ripple current rating (1.5 A vs. 2.1 A). Electrical specifications for capacitance, voltage, and tolerance are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the PCR2A180MCL1GS and PCV2A180MCL1GS are ROHS3 compliant.

Q: Does the substitute part have better performance?

A: The PCV2A180MCL1GS offers lower ESR and higher ripple current capability. However, it has a reduced maximum operating temperature rating compared to the original part.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Tape & Reel (TR) packaging for surface mount assembly and are configured as radial can SMD components.

Q: Is PCB redesign necessary to use the substitute part?

A: PCB layout review is required due to the larger footprint of the PCV2A180MCL1GS. The increased case diameter and land size may necessitate layout modifications depending on available board space.
