PCF1C181MCL1GS Equivalent & Substitute Parts

Part Overview

The PCF1C181MCL1GS is a 180 µF, 16 V aluminum polymer capacitor manufactured by Nichicon in the PCF series. This surface mount component is designed for general purpose applications requiring stable capacitance and low equivalent series resistance. The part is currently active in production with ROHS3 compliance and REACH affected status. Equivalent and substitute parts are identified to support design flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative performance characteristics better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCF1C181MCL1GS are grouped based on strict electrical and mechanical compatibility criteria. All substitute parts maintain the same capacitance (180 µF), voltage rating (16 V), and tolerance (±20%). Mechanical compatibility is determined by package type (Radial, Can - SMD), mounting type (Surface Mount), and land size footprint (10.30 mm × 10.30 mm or 8.30 mm × 8.30 mm).

Substitution is permissible when the following conditions are met:

• Capacitance value matches exactly: 180 µF
• Voltage rating is equal or greater: 16 V minimum
• Tolerance specification is equivalent: ±20%
• Operating temperature range encompasses or matches: -55°C to 105°C
• Package and mounting type are compatible: Surface Mount, Radial Can
• ESR and ripple current ratings support the application's electrical requirements
• Lifetime rating at 105°C meets or exceeds application demands

Parts are categorized as direct equivalents when all parameters align within the same footprint, or as compatible substitutes when electrical parameters are equivalent but physical dimensions differ slightly, requiring PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with ROHS3 requirements, ensuring regulatory alignment with current manufacturing standards. Selection between substitute parts depends on specific application constraints:

For applications requiring identical footprint compatibility with the PCF1C181MCL1GS (10.00 mm diameter, 10.30 mm × 10.30 mm land size), the APXA160ARA181MJ80G from Chemi-Con provides direct mechanical substitution with extended lifetime rating of 15000 hours at 105°C, compared to the 2000-hour rating of the original part.

For applications where reduced ESR is beneficial, PCF1C181MCL4GS and APXA160ARA181MHC0G both offer 16 mOhm ESR with higher ripple current capacity (4.4 A and 4.36 A respectively at 100 kHz), though these require PCB layout modification due to different physical dimensions (8.00 mm diameter with 8.30 mm × 8.30 mm land size).

For applications requiring balanced performance with minimal layout changes, PCJ1C181MCL1GS and APXE160ARA181MHA0G both provide 18 mOhm ESR and identical 8.00 mm × 10.00 mm dimensions with 8.30 mm × 8.30 mm land size.

Parts manufactured by Chemi-Con (APXA and APXE series) carry REACH Unaffected status, while Nichicon parts carry REACH Affected status. This distinction may influence supply chain decisions based on regulatory requirements in specific markets.

Frequently Asked Questions (FAQ)

Q: Can PCF1C181MCL4GS be used as a direct replacement for PCF1C181MCL1GS?

A: PCF1C181MCL4GS maintains identical electrical specifications (180 µF, 16 V, ±20% tolerance) but differs in physical dimensions. The substitute measures 8.00 mm diameter × 12.00 mm height with 8.30 mm × 8.30 mm land size, compared to the original 10.00 mm diameter × 8.00 mm height with 10.30 mm × 10.30 mm land size. PCB layout modification is required.

Q: What is the advantage of APXA160ARA181MJ80G over the original PCF1C181MCL1GS?

A: APXA160ARA181MJ80G maintains identical footprint (10.00 mm diameter, 10.30 mm × 10.30 mm land size) and electrical specifications but provides extended lifetime of 15000 hours at 105°C compared to 2000 hours for the original part. This extended rating supports applications requiring higher reliability over extended operational periods.

Q: Are all substitute parts compatible with the same PCB footprint?

A: No. Substitute parts are divided into two footprint groups: 10.30 mm × 10.30 mm land size (PCF1C181MCL1GS and APXA160ARA181MJ80G) and 8.30 mm × 8.30 mm land size (PCF1C181MCL4GS, PCJ1C181MCL1GS, RPS1C181MCN1GS, APXA160ARA181MHC0G, APXE160ARA181MHA0G). Verify land size compatibility before substitution.

Q: What is the difference between Nichicon and Chemi-Con substitute parts?

A: Both manufacturers provide equivalent electrical performance (180 µF, 16 V, ±20% tolerance). Chemi-Con parts (APXA and APXE series) carry REACH Unaffected status, while Nichicon parts carry REACH Affected status. Selection depends on supply chain and regulatory requirements specific to the application region.

Q: Can parts with different ESR values be substituted interchangeably?

A: ESR values range from 16 mOhm to 26 mOhm across substitute parts. Lower ESR values (16-18 mOhm) support higher ripple current capacity and reduced heat generation. Selection depends on application ripple current requirements. Verify that the substitute part's ESR and ripple current ratings meet or exceed application demands.

Q: What does REACH Affected versus REACH Unaffected mean for part selection?

A: REACH Affected status indicates the part may contain substances of concern regulated under REACH. REACH Unaffected status indicates the part does not contain such substances. Selection depends on regulatory requirements in the target market and customer specifications.
