Engineering Selection Recommendations

Direct Footprint Equivalent (Identical Lead Spacing and Case Diameter):

EEU-FC1V331L (Panasonic) is the only substitute with identical lead spacing (0.138" / 4.60mm) and case diameter (0.315" / 8.00mm) to the UPW1V331MPD6. This part is currently in active production status, making it the preferred choice for direct replacement without PCB modification. The EEU-FC1V331L carries AEC-Q200 automotive qualification, providing enhanced reliability documentation.

Functional Equivalents (Electrical Compatibility with Different Footprints):

All remaining substitute parts maintain identical capacitance, voltage rating, tolerance, and polarization specifications. However, they feature different lead spacing (0.197" / 5.00mm) and/or case diameters, requiring PCB layout verification before implementation. Among these, parts with 5000-hour lifetime ratings (UPJ1V331MPD, UPM1V331MPD, ELXY350ELL331MJ20S) provide extended operational life compared to the original 3000-hour specification.

Active vs. Legacy Status:

Panasonic EEU-FC series parts (EEU-FC1V331L, EEU-FC1V331, EEU-FC1V331B) are in active production, ensuring long-term availability. All Nichicon UPW, UPJ, UPM, and UPS series parts are classified as not for new designs, indicating potential future discontinuation.

Automotive Applications:

For automotive applications, EEU-FC1V331L, EEU-FC1V331, EEU-FC1V331B, UPM1V331MHD6, UPM1V331MPD, and ELXY350ELL331MJ20S carry AEC-Q200 qualification. The original UPW1V331MPD6 does not carry this certification.

Frequently Asked Questions (FAQ)

Q: Can UPW1V331MPD6 be replaced with UPW1V331MPD?

A: Yes. Both parts are Nichicon UPW series with identical capacitance, voltage, tolerance, and lead spacing (0.197" / 5.00mm). The UPW1V331MPD offers superior lifetime (5000 hours vs. 3000 hours at 105°C) and lower impedance (68 mOhms vs. 65 mOhms). Case diameter differs (0.394" vs. 0.315"), requiring PCB clearance verification.

Q: Is EEU-FC1V331L a direct replacement for UPW1V331MPD6?

A: Yes, EEU-FC1V331L is a direct footprint replacement. It matches the lead spacing (0.138" / 4.60mm) and case diameter (0.315" / 8.00mm) exactly. The part is manufactured by Panasonic and is in active production. Lifetime is 2000 hours at 105°C, which is lower than the original 3000 hours.

Q: What is the difference between UPJ1V331MHD6 and UPJ1V331MPD?

A: Both are Nichicon UPJ series with identical electrical specifications and 5000-hour lifetime. They differ in physical dimensions: UPJ1V331MHD6 has a larger case diameter (0.492" vs. 0.394") and shorter height (0.650" vs. 0.846"). Selection depends on available PCB space.

Q: Can I use ELXY350ELL331MJ20S in place of UPW1V331MPD6?

A: Electrical compatibility is confirmed (330 µF, 35 V, ±20%, polar, through-hole radial). However, physical dimensions differ significantly: lead spacing is 0.197" (vs. 0.138"), case diameter is 0.394" (vs. 0.315"), and height is 0.846" (vs. 0.787"). PCB layout modification is required. ELXY350ELL331MJ20S offers 5000-hour lifetime and AEC-Q200 automotive qualification.

Q: Why do some substitutes have different lead spacing?

A: Lead spacing variation reflects different manufacturing series and design generations. Nichicon UPW series uses 0.138" spacing, while UPJ, UPM, and UPS series use 0.197" spacing. Panasonic EEU-FC series offers both options. Lead spacing affects PCB hole pattern and must be verified before substitution.

Q: Which substitute offers the longest operational life?

A: UPJ1V331MHD6, UPJ1V331MPD, UPM1V331MHD6, UPM1V331MPD, and ELXY350ELL331MJ20S all offer 5000-hour lifetime at 105°C, compared to the original 3000 hours. UPS1V331MPD offers only 2000 hours and is not recommended for applications requiring extended life.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, matching the original UPW1V331MPD6.
