Substitute Part Grouping Explanation

Substitution for the UWS1V331MCL1GS is determined by strict equivalence across the following parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - SMD (exact match required)
• Size / Dimension: 0.394" Dia (10.00mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Surface Mount Land Size: 0.406" L x 0.406" W (10.30mm x 10.30mm) (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts are grouped into three categories based on their relationship to the main part: Similar parts from the same or different manufacturers with identical electrical and mechanical specifications, direct equivalents with active or supported product status, and upgrade options with enhanced thermal performance.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring active product status and ongoing manufacturer support, EEE-1VA331UAP (Panasonic) and TYEH1V337H10MTR (TE Connectivity) are the primary selections. EEE-1VA331UAP carries active status with AEC-Q200 automotive qualification and ROHS3 compliance. TYEH1V337H10MTR offers enhanced thermal performance with 2000 hours lifetime at 105°C and RoHS compliance, suitable for applications with elevated operating temperatures.

For designs where product status is less critical, UUR1V331MNL1GS (Nichicon) and EMVA350ADA331MJA0G (Chemi-Con) provide equivalent electrical performance with 2000 hours lifetime at 85°C. UUR1V331MNL1GS maintains Nichicon series continuity, while EMVA350ADA331MJA0G is available in cut tape packaging.

Parts marked "Not For New Designs" (EEE-1VA331P and AVS337M35G24T-F) are suitable for legacy system support and maintenance applications only.

Frequently Asked Questions (FAQ)

Q: Can EEE-1VA331UAP replace UWS1V331MCL1GS directly?

A: Yes. Both parts meet the core substitution criteria: 330 µF capacitance, 35 V rating, ±20% tolerance, identical physical dimensions (0.394" diameter), and surface mount radial can package. EEE-1VA331UAP has active product status and AEC-Q200 automotive qualification. The lifetime specification differs (1000 Hrs @ 85°C vs. 2000 Hrs @ 85°C), which must be evaluated against application requirements.

Q: What is the difference between TYEH1V337H10MTR and the main part?

A: TYEH1V337H10MTR is functionally equivalent in capacitance, voltage, and physical dimensions. The key difference is enhanced thermal performance: 2000 hours lifetime at 105°C versus 85°C for the main part, and extended operating temperature range to 105°C. This makes it suitable for higher temperature applications while maintaining identical PCB footprint compatibility.

Q: Are there packaging differences that affect PCB assembly?

A: Yes. The main part UWS1V331MCL1GS uses standard packaging (not specified). Substitute parts vary: UUR1V331MNL1GS uses Cut Tape & Digi-Reel®, EEE-1VA331P and TYEH1V337H10MTR use Tape & Reel (TR), and EMVA350ADA331MJA0G uses Cut Tape (CT). All maintain identical surface mount land size (0.406" L x 0.406" W) and mounting type, ensuring PCB compatibility. Packaging selection depends on assembly line equipment and volume requirements.

Q: Why does EEE-1VA331UAP show lower lifetime hours?

A: EEE-1VA331UAP specifies 1000 Hrs @ 85°C compared to 2000 Hrs @ 85°C for the main part. This is a design characteristic of the Panasonic S series. Applications requiring 2000-hour minimum lifetime should select TYEH1V337H10MTR, EMVA350ADA331MJA0G, or UUR1V331MNL1GS instead.

Q: Is height variation between substitute parts critical?

A: Height differences are minor (0.394" to 0.413" maximum seated height). All parts fit within standard PCB clearance envelopes for 10mm diameter radial cans. Verify clearance in your specific PCB layout if space constraints exist. The surface mount land size remains constant across all substitutes.
