Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCX1C331MCL1GS is determined by strict equivalence across the following critical parameters: capacitance value (330 µF), voltage rating (16 V or higher), tolerance (±20%), ESR characteristics (150 mOhm), thermal lifetime (2000 Hrs @ 135°C), operating temperature range (-40°C ~ 135°C), ripple current capability (500 mA @ 100 kHz), and physical package compatibility (10.00 mm diameter, surface mount radial can with 10.30 mm x 10.30 mm land size).

Substitute parts are categorized as follows:

Direct Manufacturer Equivalent: Parts from the same manufacturer (Nichicon) with identical electrical specifications and package dimensions, differing only in minor manufacturing process variations or height tolerance.

Upgrade Equivalent: Parts with identical capacitance and tolerance but higher voltage rating (25 V vs. 16 V), maintaining all other electrical and physical parameters. These provide enhanced voltage margin while preserving form factor compatibility.

Parametric Equivalent: Parts from alternative manufacturers (SURGE) meeting all electrical specifications and physical package requirements, with active product status and equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

UCX1C331MCS1GS (Direct Equivalent): This Nichicon part provides direct electrical and functional equivalence to the main part. The maximum seated height of 10.80 mm requires verification against PCB layout constraints; the additional 0.30 mm clearance may impact designs with tight vertical spacing. Both parts carry "Not For New Designs" status, indicating limited long-term availability.

UCX1E331MCL1GS (Upgrade Equivalent): This part offers superior voltage margin (25 V vs. 16 V) while maintaining identical physical dimensions and electrical performance. The higher voltage rating provides design robustness for applications subject to transient overvoltage conditions. This part also carries "Not For New Designs" status.

VUX331M1CTR-1010S (Parametric Equivalent): This SURGE component meets all electrical and physical specifications with active product status, indicating ongoing manufacturing support and supply availability. Selection of this part eliminates obsolescence risk associated with "Not For New Designs" components. Cross-manufacturer qualification may be required per organizational procurement standards.

Frequently Asked Questions (FAQ)

Q: Can UCX1C331MCS1GS be used as a direct replacement for UCX1C331MCL1GS?

A: Yes. Both parts are manufactured by Nichicon with identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), ESR (150 mOhm), and thermal lifetime (2000 Hrs @ 135°C). The maximum seated height differs by 0.30 mm (10.80 mm vs. 10.50 mm); verify clearance in your PCB layout before implementation.

Q: What is the advantage of using UCX1E331MCL1GS?

A: The UCX1E331MCL1GS provides a higher voltage rating (25 V) compared to the original 16 V specification. This upgrade maintains identical physical package dimensions and electrical performance while offering increased voltage margin. Applications operating near the 16 V limit benefit from this additional safety factor.

Q: Why should VUX331M1CTR-1010S be considered over Nichicon alternatives?

A: The VUX331M1CTR-1010S carries active product status, indicating current manufacturing and supply chain support. The Nichicon UCX series parts are classified as "Not For New Designs," signaling potential future discontinuation. For long-term supply security, the SURGE part provides equivalent performance with reduced obsolescence risk.

Q: Are all substitute parts PCB-compatible with the original design?

A: All substitute parts share identical land size (10.30 mm x 10.30 mm) and diameter (10.00 mm). The UCX1C331MCS1GS has a maximum height of 10.80 mm compared to 10.50 mm for the original part; verify vertical clearance in your specific layout. The other substitutes maintain the original 10.50 mm height.

Q: Do all parts meet the same compliance standards?

A: All parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). The VUX331M1CTR-1010S does not list REACH status in the provided data; verify REACH compliance status with the manufacturer if required for your application.
