PCF1A271MCL4GS Equivalent & Substitute Parts

Part Overview

The PCF1A271MCL4GS 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 requiring stable capacitance and low equivalent series resistance. The part is active and in production, with ROHS3 compliance and REACH affected status. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturer series or alternative designs.

Substitute Part Grouping Explanation

Substitute parts for the PCF1A271MCL4GS are grouped based on strict electrical and mechanical compatibility criteria. All substitute candidates maintain the core electrical specifications: 270 µF capacitance, 10 V rated voltage, ±20% tolerance, and aluminum polymer construction. Mechanical compatibility is ensured through identical or compatible surface mount land sizes and package classifications.

The substitution logic is based on the following allowed parameters:

• Capacitance: 270 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Aluminum Polymer (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Package Type: Radial, Can - SMD (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (compliance maintained)

Variations in ESR, lifetime rating, ripple current capacity, and physical dimensions (within compatible land sizes) are permitted when the core electrical and mechanical parameters remain constant. Parts with different series designations (PCF, PCJ, PCS, RPS from Nichicon; NPCAP-PXA from Chemi-Con) are acceptable substitutes provided all mandatory parameters align.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the PCF1A271MCL4GS. Selection among substitutes depends on application-specific requirements within the allowed parameter space.

For applications requiring the lowest ESR and highest ripple current capacity at 100 kHz, the APXA100ARA271MHC0G (Chemi-Con NPCAP-PXA series, 14 mOhm, 4.42 A) provides performance closest to the main part while offering extended lifetime (15000 Hrs @ 105°C). This part maintains identical physical dimensions and land size compatibility.

For applications where extended operational lifetime is prioritized, the PCS1A271MCL1GS (Nichicon PCS series) provides 5000 Hrs @ 105°C with ROHS3 compliance, though with slightly higher ESR (22 mOhm) and reduced ripple current capacity (3.2 A @ 100 kHz).

For space-constrained designs, the PCJ1A271MCL1GS and PCS1A271MCL1GS both offer reduced height (0.276" / 7.00 mm) while maintaining the same 8.00 mm diameter and land size compatibility. The RPS1A271MCN1GS and APXA100ARA271MJ80G feature larger 10.00 mm diameter packages and should be selected only when PCB layout accommodates the increased footprint.

Frequently Asked Questions (FAQ)

Q: Can PCJ1A271MCL1GS replace PCF1A271MCL4GS directly on the PCB?

A: Yes, PCJ1A271MCL1GS is mechanically compatible with identical 8.00 mm diameter and 8.30 mm x 8.30 mm land size. However, the reduced height (7.00 mm vs 12.00 mm) and higher ESR (21 mOhm vs 13 mOhm) must be evaluated for your specific circuit requirements.

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

A: Both manufacturers produce ROHS3 compliant 270 µF, 10 V aluminum polymer capacitors with identical electrical specifications. Chemi-Con NPCAP-PXA series parts offer extended lifetime ratings (15000 Hrs @ 105°C vs 2000-5000 Hrs), while Nichicon series vary by product line. Selection depends on application lifetime requirements and availability.

Q: Are the larger diameter parts (RPS1A271MCN1GS, APXA100ARA271MJ80G) suitable substitutes?

A: These parts are electrically equivalent but feature 10.00 mm diameter packages versus the original 8.00 mm. They require different PCB land sizes (10.30 mm x 10.30 mm) and should only be used if PCB layout can accommodate the larger footprint.

Q: Which substitute offers the best ESR performance?

A: APXA100ARA271MHC0G (Chemi-Con) provides the lowest ESR at 14 mOhm with identical physical dimensions to the PCF1A271MCL4GS, making it the closest electrical match while offering superior lifetime rating.

Q: Can I use PCS1A271MCL1GS for applications requiring 2000 Hrs @ 105°C?

A: Yes. PCS1A271MCL1GS exceeds the 2000 Hrs requirement with 5000 Hrs @ 105°C rating, providing additional operational margin. All other electrical and mechanical parameters remain compatible.
