RPS0G331MCN1GS Equivalent & Substitute Parts

Part Overview

The RPS0G331MCN1GS is a 330 µF, 4 V aluminum polymer capacitor manufactured by Nichicon in the FPCAP/RPS series. This surface mount radial can capacitor is designed for general purpose applications with an operating temperature range of -55°C to 105°C and a rated lifetime of 2000 hours at 105°C. The part is active and in production. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, improved performance characteristics, or different package geometries while maintaining core electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following core parameters: capacitance (330 µF), voltage rating (4 V), tolerance (±20%), type (aluminum polymer), mounting type (surface mount), package style (radial can SMD), and operating temperature range (-55°C to 105°C). All identified substitutes meet these baseline requirements. Variations in ESR (equivalent series resistance), ripple current capability, lifetime rating, physical dimensions, and manufacturer series are secondary parameters that may influence selection based on application-specific requirements but do not disqualify substitution eligibility.

Engineering Selection Recommendations

All substitute parts listed are ROHS3 compliant and active products. The RPS0G331MCN1GS is REACH unaffected, while PCK0G331MCO1GS and PCS0G331MCL1GS are REACH affected. Chemi-Con substitutes (APXA4R0ARA331MH70G, APXE4R0ARA331MF61G, APXF4R0ARA331MF61G) are REACH unaffected.

Selection between Nichicon and Chemi-Con alternatives depends on supply chain requirements and regulatory compliance needs. Within the Nichicon family, PCK0G331MCO1GS offers the lowest ESR (10 mOhm) and highest ripple current capability (3.9 A @ 100 kHz) in a smaller package. PCS0G331MCL1GS provides extended lifetime (5000 hours @ 105°C) with comparable ESR to the main part (20 mOhm).

Among Chemi-Con options, APXA4R0ARA331MH70G matches the physical footprint of the main part (8.00 mm diameter) while offering significantly extended lifetime (15000 hours @ 105°C) and lower ESR (25 mOhm). APXE4R0ARA331MF61G and APXF4R0ARA331MF61G provide compact packages (6.30 mm diameter, 5.80 mm height) with improved ripple current performance.

Frequently Asked Questions (FAQ)

Q: Can PCK0G331MCO1GS be used as a direct replacement for RPS0G331MCN1GS?

A: PCK0G331MCO1GS is electrically equivalent but has a smaller physical footprint (6.30 mm diameter vs. 8.00 mm). PCB layout compatibility must be verified before substitution. The part offers superior ESR (10 mOhm vs. 30 mOhm) and higher ripple current capability.

Q: What is the difference between REACH affected and REACH unaffected status?

A: REACH affected parts may contain substances of concern regulated under EU REACH regulations. REACH unaffected parts do not contain these substances. Selection depends on end-market regulatory requirements and supply chain policies.

Q: Does PCS0G331MCL1GS provide better reliability than the main part?

A: PCS0G331MCL1GS has a rated lifetime of 5000 hours at 105°C compared to 2000 hours for RPS0G331MCN1GS. This extended lifetime rating reflects improved reliability characteristics under thermal stress, though both parts operate across the same temperature range.

Q: Are Chemi-Con NPCAP™ series parts compatible with Nichicon designs?

A: Chemi-Con substitutes match the electrical specifications (330 µF, 4 V, ±20% tolerance) and mounting type (surface mount radial can). Physical dimensions vary; APXA4R0ARA331MH70G matches the main part footprint, while APXE4R0ARA331MF61G and APXF4R0ARA331MF61G use smaller packages. PCB layout verification is required.

Q: Which substitute offers the best ESR performance?

A: PCK0G331MCO1GS and APXF4R0ARA331MF61G both provide 10 mOhm ESR, the lowest among all listed parts. This represents a 67% reduction compared to the main part's 30 mOhm ESR.

Q: Can I use APXA4R0ARA331MH70G for applications requiring extended operational life?

A: APXA4R0ARA331MH70G is rated for 15000 hours at 105°C, providing 7.5 times the lifetime of the main part. This part maintains the same physical dimensions as RPS0G331MCN1GS, simplifying PCB integration for designs requiring enhanced reliability.
