Substitute Part Grouping Explanation

Substitution for the UPW1V331MPH6 is determined by strict equivalence across the following critical parameters: capacitance value (330 µF), voltage rating (35 V), tolerance (±20%), polarization (polar), and through-hole radial mounting configuration. Substitute parts must maintain mechanical compatibility with the original lead spacing, diameter, and height specifications to ensure direct board-level replacement without layout modifications.

The substitute parts are grouped into two categories based on physical dimensions and performance characteristics:

Group 1: Identical Physical Footprint (4.60mm lead spacing, 8.00mm diameter, 20.00mm height)

UPW1V331MPH6 (original, obsolete)
UPW1V331MPD6 (Nichicon, direct equivalent)
EEU-FC1V331L (Panasonic, automotive-grade equivalent)

Group 2: Larger Physical Footprint (5.00mm lead spacing, 10.00mm diameter, 16.00mm height)

UPW1V331MPD (Nichicon, similar electrical performance)
EEU-FC1V331 (Panasonic, automotive-grade equivalent)

Selection between groups depends on available PCB space and lead spacing constraints.

Engineering Selection Recommendations

For direct PCB replacement with identical footprint (4.60mm lead spacing): UPW1V331MPD6 is the primary substitute, offering identical electrical and mechanical specifications with ROHS3 compliance. EEU-FC1V331L provides an alternative with AEC-Q200 automotive qualification, though with reduced lifetime (2000 hours versus 3000 hours at 105°C).

For applications with PCB layout flexibility (5.00mm lead spacing): UPW1V331MPD offers extended lifetime performance (5000 hours at 105°C) with slightly improved ripple current handling. EEU-FC1V331 provides equivalent performance with AEC-Q200 automotive certification and active product status, supporting long-term availability.

For new designs: Panasonic EEU-FC series parts (EEU-FC1V331 or EEU-FC1V331L) are recommended due to active product status and AEC-Q200 compliance, ensuring supply chain continuity and automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can UPW1V331MPD6 be used as a direct replacement for UPW1V331MPH6? A: Yes. Both parts share identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), lifetime (3000 hours at 105°C), and physical dimensions (4.60mm lead spacing, 8.00mm diameter, 20.00mm height). The primary difference is product status; UPW1V331MPD6 is not recommended for new designs but remains functionally equivalent for legacy system repair.

Q: What is the difference between Group 1 and Group 2 substitutes? A: Group 1 substitutes maintain the original 4.60mm lead spacing and 8.00mm diameter, enabling direct PCB replacement without layout modification. Group 2 substitutes feature 5.00mm lead spacing and 10.00mm diameter, requiring PCB redesign but offering improved ripple current performance and extended lifetime in some cases.

Q: Are Panasonic EEU-FC parts compatible with the original Nichicon UPW1V331MPH6? A: Panasonic EEU-FC1V331L is mechanically and electrically compatible with identical footprint (4.60mm lead spacing). EEU-FC1V331 requires PCB modification due to larger footprint (5.00mm lead spacing). Both Panasonic parts meet AEC-Q200 automotive standards and carry ROHS3 compliance.

Q: Which substitute offers the longest operational lifetime? A: UPW1V331MPD provides the longest rated lifetime at 5000 hours at 105°C, compared to 3000 hours for the original UPW1V331MPH6. This extended lifetime comes with a larger physical footprint (5.00mm lead spacing, 10.00mm diameter).

Q: Are all substitute parts RoHS compliant? A: The original UPW1V331MPH6 is RoHS non-compliant. All listed substitutes (UPW1V331MPD6, UPW1V331MPD, EEU-FC1V331, EEU-FC1V331L) are ROHS3 compliant.

Q: What is the difference in ripple current performance between substitutes? A: UPW1V331MPH6 and EEU-FC1V331L handle 995 mA at 100 kHz. UPW1V331MPD and EEU-FC1V331 handle 1.05 A at 100 kHz, providing approximately 5.5% higher ripple current capacity. At 120 Hz, differences range from 646.75 mA to 682.5 mA depending on the part selected.
