PCF1D680MCL1GS Equivalent & Substitute Parts

Part Overview

The PCF1D680MCL1GS is a 68 µF, 20 V aluminum polymer capacitor manufactured by Nichicon in the PCF series. This surface mount component is designed for general purpose applications requiring low ESR and stable performance across extended temperature ranges. The part is currently active in production with ROHS3 compliance and REACH affected status. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, design flexibility, or application-specific performance needs.

Substitute Part Grouping Explanation

Substitute parts for the PCF1D680MCL1GS are classified based on strict electrical and mechanical parameter matching:

Direct Electrical Equivalents: Parts maintaining identical capacitance (68 µF), voltage rating (20 V), tolerance (±20%), operating temperature range (-55°C to 105°C), and package type (Radial, Can - SMD) are considered direct substitutes. ESR values within the specified range and lifetime ratings at 105°C are acceptable variations provided they do not degrade circuit performance.

Mechanical Compatibility: Substitute parts must maintain identical or compatible physical dimensions (0.394" diameter, 0.315" height maximum) and surface mount land size (0.406" L x 0.406" W) to ensure PCB layout compatibility without redesign.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and equivalent regulatory status to ensure manufacturing and supply chain continuity.

Engineering Selection Recommendations

PCF1D680MCL1GS (Primary Part): Nichicon PCF series polymer capacitor with 40 mOhm ESR and 2000 hour lifetime at 105°C. ROHS3 compliant with REACH affected status. Suitable for applications requiring standard ripple current handling at 2.6 A @ 100 kHz.

20SVP68M (Full Mechanical & Electrical Equivalent): Panasonic OS-CON™ SVP series polymer capacitor with identical physical dimensions (10.00 mm diameter, 8.00 mm height), land size, and electrical specifications (40 mOhm ESR, 2000 hour lifetime). ROHS3 compliant with REACH unaffected status. Ripple current rating of 2.4 A @ 100 kHz provides equivalent performance. Direct substitution without PCB layout modification.

PCV1D680MCL1GS (Mechanical Incompatibility): Nichicon PCV series polymer capacitor with reduced physical dimensions (8.00 mm diameter, 7.00 mm height) and smaller land size (8.30 mm x 8.30 mm). While electrically equivalent in capacitance, voltage, and tolerance, the smaller package footprint and reduced ripple current rating (1.3 A @ 100 kHz) require PCB layout redesign. Extended lifetime of 3000 hours at 105°C and higher ESR of 45 mOhm represent performance trade-offs. Not recommended as direct drop-in replacement.

Frequently Asked Questions (FAQ)

Q: Can the 20SVP68M replace the PCF1D680MCL1GS without PCB modification?

A: Yes. The 20SVP68M maintains identical physical dimensions (10.00 mm diameter, 8.00 mm height), land size (10.30 mm x 10.30 mm), and electrical specifications (68 µF, 20 V, 40 mOhm ESR). Direct substitution is possible without layout changes.

Q: Why is the PCV1D680MCL1GS not recommended as a direct substitute?

A: The PCV1D680MCL1GS has a smaller package footprint (8.00 mm diameter vs. 10.00 mm) and reduced land size (8.30 mm x 8.30 mm vs. 10.30 mm x 10.30 mm). PCB layout redesign is required. Additionally, the ripple current rating is reduced to 1.3 A @ 100 kHz compared to 2.6 A, which may limit application suitability.

Q: What are the key electrical parameters that define substitution compatibility?

A: Capacitance (68 µF), voltage rating (20 V), tolerance (±20%), operating temperature range (-55°C to 105°C), and ESR (40 mOhm nominal) are the primary electrical parameters. Ripple current handling and lifetime at 105°C are secondary considerations based on application requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PCF1D680MCL1GS, PCV1D680MCL1GS, and 20SVP68M are all ROHS3 compliant. The 20SVP68M has REACH unaffected status, while the Nichicon parts are REACH affected.

Q: What is the difference in ripple current handling between the main part and substitutes?

A: PCF1D680MCL1GS handles 2.6 A @ 100 kHz, 20SVP68M handles 2.4 A @ 100 kHz, and PCV1D680MCL1GS handles 1.3 A @ 100 kHz. Applications requiring high ripple current should prioritize the PCF or 20SVP variants.
