UPW1V331MPH Equivalent & Substitute Parts

Part Overview

The UPW1V331MPH is a 330 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as Obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement. The UPW series has been superseded by newer product lines with improved compliance ratings and extended availability. Substitute parts maintain the core electrical specifications while offering enhanced product status and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)

Parts are grouped into two categories:

Direct Substitutes (Identical Mechanical and Electrical Specifications): Parts with matching lead spacing (0.197" / 5.00mm), case diameter (0.394" / 10.00mm), and height (0.630" / 16.00mm).

Similar Substitutes (Compatible Electrical Specifications with Dimensional Variations): Parts meeting all electrical requirements but with different physical dimensions or lifetime ratings. These require PCB layout verification before implementation.

Engineering Selection Recommendations

UPW1V331MPD is the primary direct substitute. It maintains identical mechanical dimensions and electrical specifications with 5000 hours lifetime at 105°C. Product status is "Not For New Designs," but it offers ROHS3 compliance and superior availability compared to the obsolete UPW1V331MPH.

EEU-FC1V331 (Panasonic) is a direct mechanical and electrical equivalent with identical dimensions and ripple current ratings. This part carries Active product status, ROHS3 compliance, and AEC-Q200 automotive qualification, making it suitable for new designs requiring enhanced compliance and long-term availability.

UPW1V331MPD6 and EEU-FC1V331L are similar substitutes with reduced lifetime ratings (3000 and 2000 hours respectively) and different physical dimensions. These parts require PCB layout verification due to lead spacing (0.138" vs. 0.197"), case diameter (0.315" vs. 0.394"), and height (0.787" vs. 0.630") variations. Ripple current capacity is also reduced. Use only when PCB footprint accommodates the dimensional changes.

Frequently Asked Questions (FAQ)

Q: Can UPW1V331MPD be used as a direct replacement for UPW1V331MPH?

A: Yes. UPW1V331MPD is a direct substitute with identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), mechanical dimensions, and electrical performance. The primary difference is product status and compliance rating.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes maintain identical mechanical dimensions and electrical specifications. Similar substitutes meet electrical requirements but have different physical dimensions or reduced lifetime ratings. Similar substitutes require PCB layout verification before implementation.

Q: Why should I consider EEU-FC1V331 over Nichicon alternatives?

A: EEU-FC1V331 carries Active product status, ROHS3 compliance, and AEC-Q200 automotive qualification. These certifications ensure long-term availability and suitability for new designs. Nichicon UPW series parts are classified as Obsolete or Not For New Designs.

Q: Can EEU-FC1V331L be used in place of UPW1V331MPH?

A: EEU-FC1V331L meets all electrical specifications but has different physical dimensions (lead spacing 0.138" vs. 0.197", case diameter 0.315" vs. 0.394", height 0.787" vs. 0.630") and reduced lifetime (2000 hours vs. 5000 hours). PCB layout verification is required before use.

Q: What compliance certifications apply to these substitutes?

A: UPW1V331MPD and UPW1V331MPD6 are ROHS3 compliant. EEU-FC1V331 and EEU-FC1V331L are ROHS3 compliant and carry AEC-Q200 automotive qualification. UPW1V331MPH is RoHS non-compliant.

Q: Are there inventory considerations for these parts?

A: UPW1V331MPD has 1,000,400 pieces in stock. EEU-FC1V331 has 20,374 pieces in stock. EEU-FC1V331L has 3,903 pieces in stock. UPW1V331MPD6 has 3,640 pieces in stock. Availability should be confirmed with your supplier.
