PCF1D390MCL1GS Equivalent & Substitute Parts

Part Overview

The PCF1D390MCL1GS is a 39 µF, 20 V aluminum polymer capacitor manufactured by Nichicon in the PCF series. This surface mount radial can capacitor is designed for general purpose applications requiring low ESR performance and extended operational life. The part is currently active in production and widely available in inventory. Identifying equivalent substitute parts is essential for supply chain continuity, design flexibility, and procurement optimization when the primary part becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution of the PCF1D390MCL1GS is determined by strict equivalence across the following critical parameters:

Capacitance value: 39 µF (exact match required)
Voltage rating: 20 V (exact match required)
ESR: 45 mOhm (exact match required)
Lifetime specification: 2000 Hrs @ 105°C (exact match required)
Operating temperature range: -55°C to 105°C (exact match required)
Ripple current capability: 2 A @ 100 kHz (exact match required)
Package type: Radial, Can - SMD (exact match required)
Physical dimensions: 0.315" Dia × 0.276" Height (exact match required)
Mounting type: Surface Mount (exact match required)

The substitute part PVH-20V390MG70E-R2 meets all these criteria and is therefore a direct parametric equivalent. Packaging format differs (Cut Tape vs. Tape & Reel), which affects procurement and handling but does not impact electrical or mechanical compatibility.

Engineering Selection Recommendations

Both the PCF1D390MCL1GS and PVH-20V390MG70E-R2 are active production parts with full RoHS3 compliance. The PVH-20V390MG70E-R2 carries REACH Unaffected status, while the PCF1D390MCL1GS is REACH Affected. Both parts carry EAR99 ECCN classification and identical HTSUS codes, confirming regulatory and trade alignment.

The surface mount land size variation (8.30 mm vs. 8.40 mm) is within standard PCB design tolerances and does not preclude direct substitution on existing layouts. The packaging format difference (Cut Tape vs. Tape & Reel) affects procurement logistics and automated assembly handling but does not impact electrical performance or mechanical fit.

Selection between these parts should be based on supply availability, packaging requirements for your assembly process, and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can the PVH-20V390MG70E-R2 be used as a direct replacement for the PCF1D390MCL1GS on existing PCBs?

A: Yes. All critical electrical parameters (capacitance, voltage, ESR, ripple current, and lifetime) are identical. The physical dimensions and mounting type are equivalent. The minor variation in surface mount land size (0.04 mm difference) is within standard PCB manufacturing tolerances and does not require layout modification.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume production or manual assembly. Both formats contain identical components; the difference is in procurement and handling logistics.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications. The PCF1D390MCL1GS is REACH Affected, while the PVH-20V390MG70E-R2 is REACH Unaffected. For applications subject to REACH regulations, the Elna part may offer simplified compliance documentation.

Q: What parameters must remain identical for substitution to be valid?

A: Capacitance (39 µF), voltage rating (20 V), ESR (45 mOhm), lifetime specification (2000 Hrs @ 105°C), operating temperature range (-55°C to 105°C), ripple current (2 A @ 100 kHz), package type (Radial, Can - SMD), and physical dimensions (0.315" Dia × 0.276" Height) must all match exactly. Any deviation in these parameters disqualifies a part as a direct equivalent.

Q: Which part should I select for new designs?

A: Both parts are suitable for new designs. Selection should be based on component availability, your assembly process packaging requirements, and supply chain considerations. Verify current inventory levels and lead times with your component distributor.
