PCF1A271MCL1GS Equivalent & Substitute Parts

Part Overview

The PCF1A271MCL1GS is a 270 µF, 10 V aluminum polymer capacitor manufactured by Nichicon in the PCF 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 RoHS3 compliant and REACH affected.

Substitute parts are necessary when the original PCF1A271MCL1GS becomes unavailable due to supply constraints, end-of-life status, or when design requirements necessitate alternative electrical or mechanical characteristics such as lower ESR, extended lifetime, or different package dimensions.

Engineering Selection Recommendations

All listed substitute parts are Active status products and RoHS3 compliant, ensuring regulatory compliance and ongoing availability.

For direct mechanical and electrical compatibility with minimal design changes: PCJ1A271MCL1GS offers the closest dimensional profile with a smaller footprint (0.315" diameter, 0.276" height) while maintaining equivalent electrical performance.

For improved ESR performance: PCF1A271MCL4GS (13 mOhm) and APXA100ARA271MHC0G (14 mOhm) provide lower ESR and higher ripple current capability. Note that PCF1A271MCL4GS has different dimensions (0.315" diameter, 0.472" height) and APXA100ARA271MHC0G is a Chemi-Con product.

For extended lifetime applications: PCS1A271MCL1GS (5000 hours @ 105°C) and both Chemi-Con NPCAP™-PXA series parts (15000 hours @ 105°C) provide significantly longer operational life. The Chemi-Con parts carry REACH Unaffected status, whereas Nichicon parts are REACH Affected.

For same-diameter footprint retention: RPS1A271MCN1GS and APXA100ARA271MJ80G both maintain the 0.394" (10.00 mm) diameter of the original PCF1A271MCL1GS.

Frequently Asked Questions (FAQ)

Q: Can PCF1A271MCL4GS be used as a direct replacement for PCF1A271MCL1GS?

A: PCF1A271MCL4GS meets all core electrical parameters (270 µF, 10 V, ±20%, aluminum polymer, RoHS3). However, it has different physical dimensions: 0.315" diameter with 0.472" height versus the original 0.394" diameter with 0.315" height. PCB layout verification is required before substitution.

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

A: Both manufacturers provide equivalent electrical specifications (270 µF, 10 V, ±20%). Chemi-Con NPCAP™-PXA series parts (APXA100ARA271MHC0G and APXA100ARA271MJ80G) offer extended lifetime (15000 hours @ 105°C) and REACH Unaffected status, while Nichicon parts provide standard 2000-5000 hour lifetimes and are REACH Affected.

Q: Which substitute has the lowest ESR?

A: APXA100ARA271MHC0G (Chemi-Con) has the lowest ESR at 14 mOhm, followed by PCF1A271MCL4GS (Nichicon) at 13 mOhm. Lower ESR reduces heat generation and improves ripple current handling.

Q: Are all substitutes surface mount compatible?

A: Yes. All listed parts are surface mount radial can capacitors with identical mounting type and compatible land sizes within their respective diameter classes (0.315" or 0.394" diameter).

Q: Which substitute maintains the exact same footprint as PCF1A271MCL1GS?

A: No substitute maintains identical dimensions. PCJ1A271MCL1GS offers the closest profile with matching 0.315" diameter but different height. For same-diameter retention, RPS1A271MCN1GS and APXA100ARA271MJ80G both use 0.394" diameter.

Q: What is the impact of ESR differences on circuit performance?

A: ESR affects impedance, heat dissipation, and voltage ripple. Lower ESR (13-14 mOhm) reduces heat and improves transient response. Higher ESR (21-25 mOhm) increases heat generation but remains within acceptable ranges for general purpose applications at rated ripple currents.
