• Tolerance: ±20% (exact match required)
• ESR: 150 mOhms (exact match required)
• Ripple Current @ 120 Hz: 250 mA (exact match required)
• Ripple Current @ 100 kHz: 500 mA (exact match required)

Thermal & Reliability Parameters:

• Lifetime @ 135°C: 2000 Hrs (exact match required)
• Operating Temperature Range: -40°C ~ 135°C (exact match required)

Mechanical & Packaging Parameters:

• Size / Dimension: 0.394" Dia (10.00 mm) (exact match required)
• Height - Seated (Max): 0.413" (10.50 mm) (exact match required)
• Surface Mount Land Size: 0.406" L x 0.406" W (10.30 mm x 10.30 mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: Radial, Can - SMD (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)

The UCX1A331MCL1GS from Nichicon meets all specified parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

VUX331M1ATR-1010S (SURGE): This part carries Active product status, indicating ongoing manufacturer support and availability for new design implementations. The component is ROHS3 compliant and maintains MSL Level 1 (Unlimited) moisture sensitivity rating, suitable for standard manufacturing and storage environments.

UCX1A331MCL1GS (Nichicon): This substitute part is electrically and mechanically equivalent to the VUX331M1ATR-1010S across all specified parameters. However, the UCX1A331MCL1GS carries "Not For New Designs" product status, indicating that Nichicon does not recommend this part for new design implementations. This designation reflects manufacturer lifecycle management and does not indicate functional deficiency.

Selection Basis:

• For new designs: VUX331M1ATR-1010S is the primary selection due to Active product status.
• For legacy system maintenance or component replacement: UCX1A331MCL1GS is a valid parametric equivalent when VUX331M1ATR-1010S availability is constrained, provided that design documentation and qualification history support substitution.

Both parts are ROHS3 compliant and carry identical electrical, thermal, and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: What makes UCX1A331MCL1GS a valid substitute for VUX331M1ATR-1010S?

A: The UCX1A331MCL1GS matches all critical electrical parameters (330 µF capacitance, 10 V rating, ±20% tolerance, 150 mOhms ESR), thermal performance (2000 Hrs @ 135°C), ripple current ratings (250 mA @ 120 Hz, 500 mA @ 100 kHz), mechanical dimensions (10.00 mm diameter, 10.50 mm height), and compliance certifications (ROHS3, MSL Level 1). Substitution is based on exact parameter equivalence.

Q: Why does the substitute part have "Not For New Designs" status?

A: Product status reflects manufacturer lifecycle management decisions and does not indicate functional or performance deficiency. The "Not For New Designs" designation for UCX1A331MCL1GS indicates that Nichicon has transitioned this part to end-of-life or legacy status. This part remains suitable for replacement applications in existing systems where design qualification has already been completed.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. Both parts share identical mechanical specifications: 0.394" diameter (10.00 mm), 0.413" maximum seated height (10.50 mm), and 0.406" x 0.406" surface mount land size (10.30 mm x 10.30 mm). Both use radial, can-style SMD packaging and are compatible with identical PCB footprints.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both VUX331M1ATR-1010S and UCX1A331MCL1GS are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. Both operate across the identical temperature range (-40°C ~ 135°C) and maintain 2000 hours lifetime at 135°C.

Q: What is the difference in ESR between these parts?

A: There is no difference. Both parts specify 150 mOhms equivalent series resistance, ensuring identical electrical performance in ripple current applications and thermal management characteristics.

Q: Can I use UCX1A331MCL1GS in a new design application?

A: While UCX1A331MCL1GS is electrically and mechanically equivalent to VUX331M1ATR-1010S, the substitute part carries "Not For New Designs" status from the manufacturer. For new design implementations, VUX331M1ATR-1010S is the recommended selection due to its Active product status and ongoing manufacturer support.
