RFS0G151MCN1GS Equivalent & Substitute Parts

Part Overview

The RFS0G151MCN1GS is a 150 µF, 4 V aluminum polymer capacitor manufactured by Nichicon in the FPCAP/RFS 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 currently active and in stock, with RoHS3 compliance and REACH unaffected status. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, ESR, and ripple current characteristics) and compatible mechanical packaging for surface mount assembly.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RFS0G151MCN1GS is determined by the following core parameters:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 4 V (exact match required)
• Type: Aluminum Polymer (exact match required)
• Tolerance: ±20% (exact match required)
• ESR: 22 mOhm (primary electrical characteristic)
• Lifetime @ 105°C: 2000 Hrs minimum (equal or greater acceptable)
• Operating Temperature: -55°C to 105°C (exact match required)
• Package: Radial, Can - SMD (exact match required)
• Mounting Type: Surface Mount (exact match required)

Substitute parts are grouped into two categories: direct equivalents (matching all primary electrical and mechanical specifications) and compatible alternatives (matching core electrical specifications with acceptable variations in physical dimensions and secondary characteristics such as ripple current or ESR within functional tolerance).

Parameter Comparison

Engineering Selection Recommendations

All four parts listed meet the core electrical specifications for 150 µF, 4 V aluminum polymer capacitors with RoHS3 compliance and active product status.

APXE4R0ARA151ME61G (Chemi-Con NPCAP™-PXE series) is a direct electrical and mechanical equivalent to the RFS0G151MCN1GS, matching the 5.00 mm diameter, 22 mOhm ESR, and 2.61 A ripple current at 100 kHz. Both parts share identical land size requirements (5.30 mm x 5.30 mm) and REACH unaffected status.

PCF0G151MCL4GB (Nichicon PCF series) is electrically equivalent but features a larger 6.30 mm diameter package with increased ripple current capability (2.8 A @ 100 kHz). This part requires different PCB land size (6.60 mm x 6.60 mm) and has REACH affected status.

APXA4R0ARA151MF60G (Chemi-Con NPCAP™-PXA series) is electrically compatible with extended lifetime (15000 Hrs @ 105°C) and slightly elevated ESR (26 mOhm). This part also uses the larger 6.30 mm diameter package with 6.60 mm x 6.60 mm land size requirements.

Selection should account for PCB layout constraints, available land size, and regulatory compliance requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can PCF0G151MCL4GB be used as a direct replacement for RFS0G151MCN1GS on the same PCB?

A: No. While both parts are electrically equivalent 150 µF, 4 V aluminum polymer capacitors, the PCF0G151MCL4GB has a larger physical diameter (6.30 mm vs. 5.00 mm) and requires different surface mount land size (6.60 mm x 6.60 mm vs. 5.30 mm x 5.30 mm). PCB layout modification is required.

Q: What is the difference between APXE4R0ARA151ME61G and APXA4R0ARA151MF60G?

A: Both are Chemi-Con aluminum polymer capacitors with 150 µF, 4 V specifications. The APXE4R0ARA151ME61G has 22 mOhm ESR and 2000 hour lifetime at 105°C. The APXA4R0ARA151MF60G has 26 mOhm ESR and extended 15000 hour lifetime at 105°C. The APXE series matches the original part's electrical characteristics more closely, while the APXA series offers improved longevity.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four parts listed (RFS0G151MCN1GS, PCF0G151MCL4GB, APXE4R0ARA151ME61G, and APXA4R0ARA151MF60G) are RoHS3 compliant.

Q: Does REACH compliance affect part selection?

A: REACH status is provided for regulatory documentation purposes. RFS0G151MCN1GS, APXE4R0ARA151ME61G, and APXA4R0ARA151MF60G are REACH unaffected. PCF0G151MCL4GB is REACH affected. Selection should align with application regulatory requirements.

Q: Which substitute part has the lowest ESR?

A: RFS0G151MCN1GS, PCF0G151MCL4GB, and APXE4R0ARA151ME61G all have 22 mOhm ESR. APXA4R0ARA151MF60G has 26 mOhm ESR.

Q: Can I use a substitute part with different physical dimensions if my PCB has space?

A: Yes, provided the PCB layout is modified to accommodate the different land size requirements. Verify that the new land size (6.60 mm x 6.60 mm for larger packages) does not conflict with adjacent components or trace routing.
