UCD1K3R3MCL1GS Equivalent & Substitute Parts

Part Overview

The UCD1K3R3MCL1GS is a 3.3 µF, 80 V aluminum electrolytic capacitor manufactured by Nichicon in the UCD series. This surface mount radial can capacitor is designed for automotive applications and maintains a 2000-hour lifetime at 105°C operating temperature. The part is currently active in production with AEC-Q200 automotive qualification. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution eligibility for the UCD1K3R3MCL1GS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Capacitance value (3.3 µF), voltage rating (80 V), and tolerance (±20%) must match exactly. Thermal performance, defined by lifetime at rated temperature (2000 Hrs @ 105°C), must be equivalent or superior.

Mechanical Parameters: Package type (Radial, Can - SMD), case diameter (5.00mm), case height (6.10mm), and land size (5.30mm x 5.30mm) must be identical to ensure PCB compatibility without layout redesign.

Environmental & Compliance: Operating temperature range (-55°C ~ 105°C), AEC-Q200 automotive qualification, and RoHS3 compliance must be maintained.

The identified substitute part EEE-FK1K3R3R meets all these criteria and is therefore classified as a parametric equivalent.

Engineering Selection Recommendations

Both the UCD1K3R3MCL1GS and EEE-FK1K3R3R are active production parts with identical AEC-Q200 automotive qualification and ROHS3 compliance status. Selection between these parts may be based on availability, supply chain logistics, or design flexibility requirements. Both parts satisfy the electrical and mechanical requirements for automotive aluminum electrolytic capacitor applications requiring 3.3 µF at 80 V with surface mount radial can packaging.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1K3R3R be used as a direct replacement for UCD1K3R3MCL1GS?

A: Yes. Both parts are parametric equivalents with identical capacitance (3.3 µF), voltage rating (80 V), tolerance (±20%), thermal lifetime (2000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), and physical dimensions (5.00mm diameter, 6.10mm height, 5.30mm x 5.30mm land size). No PCB layout modifications are required.

Q: Are there differences in ripple current specifications?

A: Ripple current at high frequency (100 kHz) is identical at 25 mA for both parts. Low frequency ripple current (120 Hz) differs: UCD1K3R3MCL1GS specifies 12.5 mA while EEE-FK1K3R3R specifies 18.75 mA. Both values are within acceptable operating parameters for this capacitor category.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both UCD1K3R3MCL1GS and EEE-FK1K3R3R carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: Are there compliance or environmental differences?

A: Both parts are ROHS3 compliant. UCD1K3R3MCL1GS is REACH Affected; EEE-FK1K3R3R is REACH Unaffected. Both carry EAR99 ECCN classification and identical HTSUS code 8532.22.0020
