Engineering Selection Recommendations

The ELXZ350ELL331MJ16S qualifies as a direct parametric equivalent for the UPW1V331MPD1CT based on matching electrical specifications, mechanical dimensions, and automotive compliance ratings. Both components are active products with AEC-Q200 certification, ensuring suitability for automotive circuit applications.

Selection between these parts should be based on availability, lead time, and procurement requirements. The Chemi-Con ELXZ350ELL331MJ16S currently has higher inventory availability (2438 units) compared to the Nichicon UPW1V331MPD1CT (734 units), which may influence supply chain decisions.

Frequently Asked Questions (FAQ)

Q: Can the ELXZ350ELL331MJ16S be used as a direct replacement for the UPW1V331MPD1CT?

A: Yes. Both components share identical electrical ratings (330 µF, 35 V, ±20% tolerance), thermal specifications (5000 Hrs @ 105°C), mechanical dimensions (10.00 mm diameter, 17.50 mm height, 5.00 mm lead spacing), and automotive compliance (AEC-Q200). They are mechanically and electrically interchangeable in through-hole PCB applications.

Q: Are there differences in ripple current ratings between these parts?

A: The ripple current at 120 Hz differs between the two parts: the UPW1V331MPD1CT is rated for 682.5 mA while the ELXZ350ELL331MJ16S is rated for 525 mA at this frequency. However, both are rated identically at 100 kHz (1.05 A), which is the primary ripple current specification for most power supply and filtering applications. Circuit design should account for the lower 120 Hz rating of the substitute if low-frequency ripple current is a critical parameter.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the UPW1V331MPD1CT and ELXZ350ELL331MJ16S carry AEC-Q200 certification and are classified for automotive applications, meeting industry standards for automotive-grade electronic components.

Q: Are the physical dimensions identical?

A: Yes. Both components are radial, through-hole capacitors with identical case diameter (10.00 mm), height (17.50 mm), and lead spacing (5.00 mm), ensuring direct PCB footprint compatibility without layout modifications.

Q: What is the operating temperature range for both parts?

A: Both components operate across the identical temperature range of -55°C to 105°C, with a rated lifetime of 5000 hours at the maximum operating temperature of 105°C.
