Substitute Part Grouping Explanation

Substitution of the UCX1E331MCL1GS is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR: 150 mOhm (exact match required)
• Lifetime rating: 2000 Hrs @ 135°C (exact match required)
• Operating temperature range: -40°C ~ 135°C (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.394" Dia × 0.413" Height (exact match required)
• Surface mount land size: 0.406" L × 0.406" W (exact match required)
• Ripple current specifications: 250 mA @ 120 Hz and 500 mA @ 100 kHz (exact match required)
• RoHS3 compliance and MSL Level 1 rating (exact match required)

The VUX331M1ETR-1010S from SURGE meets all these criteria and is classified as an active product, making it suitable for new applications and ongoing production.

Parameter Comparison

Engineering Selection Recommendations

The VUX331M1ETR-1010S is the direct equivalent substitute for the UCX1E331MCL1GS. Both components are ROHS3 compliant and carry MSL Level 1 rating, ensuring compatibility with modern manufacturing and environmental standards. The primary distinction is product status: the UCX1E331MCL1GS is designated not for new designs, while the VUX331M1ETR-1010S maintains active status. For new circuit designs and ongoing production, the VUX331M1ETR-1010S is the appropriate selection. For legacy system maintenance where the original UCX1E331MCL1GS is specified, the VUX331M1ETR-1010S provides full functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the VUX331M1ETR-1010S be used as a direct replacement for the UCX1E331MCL1GS?

A: Yes. Both components share identical electrical specifications (330 µF, 25 V, ±20% tolerance, 150 mOhm ESR, 2000 Hrs @ 135°C), identical physical dimensions (0.394" diameter, 0.413" height), and identical surface mount land sizes (0.406" × 0.406"). No circuit modifications or PCB layout changes are required.

Q: What is the significance of the "Not For New Designs" status on the UCX1E331MCL1GS?

A: This designation indicates that Nichicon has discontinued active development and promotion of this part number. The VUX331M1ETR-1010S, classified as active, is the recommended choice for new product development and future production runs.

Q: Are there any differences in packaging or handling between these two parts?

A: Both components are supplied in Tape & Reel (TR) packaging with MSL Level 1 rating, indicating unlimited shelf life under normal storage conditions. Handling and storage procedures are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the UCX1E331MCL1GS and VUX331M1ETR-1010S are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status for these parts?

A: The UCX1E331MCL1GS has 1202 pieces in stock, while the VUX331M1ETR-1010S has 698 pieces in stock. Both are available as new original components.
