Substitute Part Grouping Explanation

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

Capacitance value: 330 µF (exact match required)
Voltage rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime specification: 5000 Hrs @ 105°C (exact match required)
Operating temperature range: -55°C ~ 105°C (exact match required)
Package type: Radial, Can - SMD (exact match required)
Physical dimensions: 0.394" Dia (10.00mm) and 0.413" Height (10.50mm) (exact match required)
Surface mount land size: 0.406" L × 0.406" W (10.30mm × 10.30mm) (exact match required)
Mounting type: Surface Mount (exact match required)
Polarization: Polar (exact match required)

All identified substitute parts meet these criteria. Variations in ripple current ratings, impedance, and ESR values do not disqualify substitution when all primary electrical and mechanical parameters align.

Engineering Selection Recommendations

UUD1V331MNL1GS is the primary direct substitute from Nichicon, maintaining identical electrical specifications and ripple current characteristics while offering active product status and ROHS3 compliance. This part is recommended for applications requiring minimal design validation.

UCD1V331MNL1GS provides enhanced ripple current performance (425 mA @ 120 Hz, 850 mA @ 100 kHz) and lower impedance (80 mOhms) compared to the original part, with active status and ROHS3 compliance. Selection is appropriate when higher ripple current capacity is beneficial.

KEMET EXV337M035A9PAA and EXV337M035S9PAA offer the highest ripple current ratings (595 mA @ 120 Hz) and are AEC-Q200 rated for automotive applications. These parts carry higher impedance (120 mOhms) and are suitable for general-purpose and automotive designs.

Rubycon 35TLV330M10X10.5 and Panasonic EEE-FK1V331GP provide balanced performance with 80 mOhms impedance, AEC-Q200 automotive certification, and active product status. The Panasonic part offers the highest ripple current at 120 Hz (637.5 mA).

Chemi-Con EMZL350ARA331MJA0G delivers 80 mOhms impedance with AEC-Q200 automotive rating and active status, suitable for automotive applications requiring Alchip™ series components.

All substitute parts are ROHS3 compliant and carry active product status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can UUD1V331MNR1GS be directly replaced with UUD1V331MNL1GS?

A: Yes. Both parts are from Nichicon's UUD series with identical electrical specifications, operating temperature range, package dimensions, and land size. The primary difference is product status (obsolete vs. active) and RoHS compliance. UUD1V331MNL1GS is the direct successor.

Q: What is the difference between Nichicon UUD and UCD series substitutes?

A: Both maintain 330 µF, 35 V specifications and identical physical dimensions. The UCD series provides enhanced ripple current capacity (425 mA @ 120 Hz vs. 335 mA) and lower impedance (80 mOhms vs. 90 mOhms), making it suitable for applications with higher AC current demands.

Q: Are KEMET EXV337M035A9PAA and EXV337M035S9PAA interchangeable?

A: Yes. Both are KEMET EXV series parts with identical electrical specifications, dimensions, and ripple current ratings. They differ only in packaging (Tape & Reel) and are functionally equivalent for circuit design purposes.

Q: Do all substitute parts meet automotive standards?

A: Most substitute parts carry AEC-Q200 certification: UUD1V331MNL1GS, UCD1V331MNL1GS, EXV337M035S9PAA, 35TLV330M10X10.5, EEE-FK1V331GP, and EMZL350ARA331MJA0G. EXV337M035A9PAA does not list AEC-Q200 rating but is suitable for general-purpose applications.

Q: What is the impact of impedance differences on circuit performance?

A: Impedance variations (80 mOhms to 120 mOhms) affect high-frequency filtering characteristics. Lower impedance (80 mOhms) provides superior high-frequency noise suppression. Higher impedance (120 mOhms) is acceptable in applications where impedance is not a critical design parameter.

Q: Are all substitute parts available in the same packaging options?

A: Packaging varies. UUD1V331MNL1GS is available in Cut Tape (CT) & Digi-Reel®. KEMET, Rubycon, Panasonic, and Chemi-Con parts are supplied in Tape & Reel (TR) format. Confirm packaging requirements with your procurement process.

Q: Can I use parts with higher ripple current ratings as direct substitutes?

A: Yes. Parts with higher ripple current ratings (such as EEE-FK1V331GP at 637.5 mA @ 120 Hz) are fully compatible substitutes. Higher ratings provide additional design margin without affecting circuit functionality.

Q: What is the significance of RoHS compliance for this part?

A: All active substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements. The original UUD1V331MNR1GS is RoHS non-compliant due to its obsolete status. Compliance is mandatory for new designs and production runs.
