Substitute Part Grouping Explanation

Substitution of the UCD1V331MNQ1GS 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)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.394" Dia (10.00mm), Height 0.425" (10.80mm) (exact match required)
• Surface mount land size: 0.406" L x 0.406" W (10.30mm x 10.30mm) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Lifetime rating: 5000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)
• AEC-Q200 automotive qualification (exact match required)

The EEE-FK1V331GV from Panasonic Electronic Components meets all these criteria and qualifies as a parametric equivalent substitute.

Frequently Asked Questions (FAQ)

Q: Can the EEE-FK1V331GV replace the UCD1V331MNQ1GS in automotive designs?

A: Yes. The EEE-FK1V331GV meets all parametric requirements for direct substitution, including identical capacitance, voltage rating, tolerance, physical dimensions, mounting type, lifetime rating, operating temperature range, and AEC-Q200 automotive qualification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical package dimensions: 0.394" diameter (10.00mm), 0.425" maximum seated height (10.80mm), and 0.406" x 0.406" surface mount land size (10.30mm x 10.30mm). PCB layout and assembly tooling require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the UCD1V331MNQ1GS and EEE-FK1V331GV are ROHS3 compliant and carry AEC-Q200 automotive qualification, meeting identical regulatory and quality requirements.

Q: What is the difference in ripple current specifications?

A: Both parts support 850 mA ripple current at 100 kHz. The UCD1V331MNQ1GS specifies 425 mA at 120 Hz, while the EEE-FK1V331GV specifies 637.5 mA at 120 Hz. Both exceed the low-frequency ripple current requirement of the primary part.

Q: Are there any moisture sensitivity differences?

A: The UCD1V331MNQ1GS lists moisture sensitivity as not applicable. The EEE-FK1V331GV is rated MSL 1 (Unlimited), indicating superior moisture resistance. This represents an improvement in handling and storage conditions.
