Substitute Part Grouping Explanation

Substitute parts for the PCF1C390MCL1GS are classified based on the following electrical and mechanical compatibility criteria:

Direct Equivalents maintain identical capacitance (39 µF), voltage rating (16 V), tolerance (±20%), and surface mount package footprint. These parts differ only in packaging variant or minor height specifications while preserving the same land size and mounting requirements.

Upgraded Alternatives provide enhanced performance through improved ESR characteristics or extended lifetime ratings at 105°C, while maintaining the same core electrical specifications and general physical dimensions.

Similar Alternatives share the same capacitance, voltage, and tolerance values but differ in physical size (diameter and height), ESR performance, or ripple current ratings. These require PCB layout verification to confirm mechanical compatibility.

Cross-Manufacturer Alternatives from Chemi-Con provide equivalent electrical performance with different series designations and may offer extended lifetime ratings or alternative ESR specifications.

The following parameters determine substitution eligibility:

Capacitance: 39 µF (fixed requirement)
Voltage Rating: 16 V (fixed requirement)
Tolerance: ±20% (fixed requirement)
Package Type: Radial, Can - SMD (fixed requirement)
Mounting Type: Surface Mount (fixed requirement)
Physical Dimensions: Case diameter, height, and land size (variable within compatibility limits)
ESR: 24–45 mOhm (acceptable range for general purpose applications)
Lifetime: 2000–15000 hours @ 105°C (performance variable)

Engineering Selection Recommendations

Direct Substitution (Same Footprint): PCF1C390MCL4GB is a direct substitute with identical electrical specifications and land size (6.60 mm x 6.60 mm). The reduced height (5.50 mm vs. 6.00 mm) provides additional PCB clearance without affecting electrical performance. Both parts are Active status and RoHS3 compliant.

Performance Enhancement (Extended Lifetime): PCS1C390MCL9GS offers improved reliability with 5000-hour lifetime at 105°C compared to 2000 hours for the original part. ESR is marginally lower (30 mOhm vs. 31 mOhm), and the footprint remains identical. This upgrade is suitable for applications requiring extended operational life.

Compact Footprint Alternatives: PCJ1C390MCL1GS and APXE160ARA390ME61G reduce the case diameter to 5.00 mm with corresponding land size reduction to 5.30 mm x 5.30 mm. These parts are suitable for space-constrained designs. PCJ1C390MCL1GS maintains 2000-hour lifetime, while APXE160ARA390ME61G (Chemi-Con) provides equivalent performance with identical specifications.

Low ESR Performance: RPA1C390MCN1GS delivers the lowest ESR at 24 mOhm with the highest ripple current capability (2.5 A @ 100 kHz). Physical dimensions are compatible with the original part (6.30 mm diameter, 5.70 mm height). This part is suitable for high-ripple-current applications.

Extended Lifetime (15000 Hours): APXA160ARA390MF60G from Chemi-Con provides the longest operational life at 15000 hours @ 105°C. The footprint matches the original part (6.60 mm x 6.60 mm land size), making it a direct mechanical replacement with superior reliability characteristics.

All substitute parts maintain Active product status and full RoHS3 compliance, ensuring regulatory compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can PCF1C390MCL4GB replace PCF1C390MCL1GS directly on the PCB? A: Yes. Both parts share identical land size (6.60 mm x 6.60 mm), capacitance (39 µF), voltage rating (16 V), and ESR (31 mOhm). The only difference is height (5.50 mm vs. 6.00 mm), which provides additional clearance without affecting electrical function.

Q: What is the difference between Nichicon PCF and PCS series? A: The PCS series offers extended lifetime (5000 hours @ 105°C) compared to PCF (2000 hours @ 105°C). Both maintain the same capacitance, voltage, and tolerance. ESR and ripple current specifications vary slightly between series variants.

Q: Can I use a smaller footprint part like PCJ1C390MCL1GS in place of PCF1C390MCL1GS? A: Mechanical compatibility must be verified. PCJ1C390MCL1GS has a smaller diameter (5.00 mm vs. 6.30 mm) and reduced land size (5.30 mm x 5.30 mm vs. 6.60 mm x 6.60 mm). The PCB layout must accommodate the smaller footprint. Electrical specifications are compatible.

Q: What advantage does RPA1C390MCN1GS offer? A: RPA1C390MCN1GS provides the lowest ESR (24 mOhm) and highest ripple current capability (2.5 A @ 100 kHz). This part is optimized for applications with high AC ripple current requirements. Physical dimensions are compatible with the original part.

Q: Is APXA160ARA390MF60G from Chemi-Con a suitable replacement? A: Yes. APXA160ARA390MF60G maintains identical electrical specifications (39 µF, 16 V, ±20%) and footprint (6.60 mm x 6.60 mm land size). The primary advantage is extended lifetime (15000 hours @ 105°C vs. 2000 hours). RoHS3 compliance is confirmed.

Q: How do I determine which substitute part is best for my application? A: Selection depends on three factors: (1) Physical space constraints—use compact footprint parts (5.00 mm diameter) if space is limited; (2) Ripple current requirements—use RPA1C390MCN1GS for high-ripple applications; (3) Lifetime requirements—use PCS series or APXA160ARA390MF60G for extended operational life. All parts maintain the required 39 µF, 16 V, ±20% specification.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts are RoHS3 compliant and suitable for applications requiring regulatory compliance.
