Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied strictly to the provided parameters:

Primary Substitution Criteria:

Capacitance: 330 µF (exact match required)
Voltage Rating: 25 V minimum (equal or higher acceptable)
Tolerance: ±20% (matching or tighter tolerance acceptable)
Package Type: Radial, Can (mechanical compatibility)
Lead Spacing: 0.197" (5.00 mm) (PCB layout compatibility)
Case Diameter: 0.394" (10.00 mm) (board space compatibility)
Mounting Type: Through Hole (assembly process compatibility)

Secondary Considerations:

Lifetime @ 105°C: 2000 hours or greater (reliability enhancement acceptable)
Operating Temperature Range: -55°C to 105°C minimum (full range match or equivalent)
Ripple Current: 315 mA @ 120 Hz or greater (performance enhancement acceptable)

Parts are grouped as follows:

Direct Equivalents: Same electrical specifications (330 µF, 25 V, ±20%, 2000 Hrs @ 105°C) with identical or compatible mechanical dimensions.

Upgraded Alternatives: Enhanced lifetime (5000 Hrs or 4000 Hrs @ 105°C), higher voltage rating (35 V), or improved ripple current handling while maintaining identical capacitance, tolerance, and mechanical compatibility.

Similar Alternatives: Matching core electrical specifications with minor dimensional variations (lead spacing or case diameter differences) or reduced lifetime ratings, suitable only where mechanical constraints permit.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

UVZ1E331MPD is the direct equivalent to UVZ1E331MPH, maintaining identical electrical and mechanical specifications. This part carries ROHS3 compliance and is available in higher inventory quantities (55,519 pcs). Use this part for immediate substitution in existing designs where the obsolete UVZ1E331MPH is currently specified.

For Enhanced Reliability (New Designs):

UPW1E331MPD offers a 5000-hour lifetime at 105°C compared to the original 2000 hours, with improved ripple current handling (494 mA @ 120 Hz). This Nichicon part maintains identical mechanical compatibility and voltage rating while providing extended operational reliability. ROHS3 compliance is confirmed.

EEU-FC1E331 from Panasonic provides a 3000-hour lifetime with superior ripple current performance (490.8 mA @ 120 Hz) and carries AEC-Q200 automotive qualification. This part is in active production status and offers enhanced reliability for applications requiring automotive-grade components.

For Higher Voltage Margin:

UVZ1V331MPD provides a 35 V rating while maintaining the same 330 µF capacitance and 2000-hour lifetime. This part is suitable where circuit design permits higher voltage rating for improved safety margin. ROHS3 compliance is confirmed.

For Active Production Status:

MAL215066331E3 and MAL215056331E3 from Vishay are both in active production with 4000-hour lifetimes and AEC-Q200 automotive qualification. These parts feature slightly increased height (0.512" vs. 0.492") but maintain all other mechanical dimensions. Both carry ROHS3 compliance.

Not Recommended for Direct Substitution:

ECA-1EHG331 has reduced lead spacing (0.138" vs. 0.197") and smaller case diameter (0.315" vs. 0.394"), making it unsuitable for direct PCB replacement without layout modification. Use only where mechanical constraints have been verified.

SEK331M025ST from Cornell Dubilier maintains mechanical compatibility but carries a higher ESR specification (640 mOhm) and lacks ripple current data in the provided parameters. Verify ripple current requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can UVZ1E331MPD be used as a direct replacement for UVZ1E331MPH?

A: Yes. UVZ1E331MPD is electrically and mechanically identical to UVZ1E331MPH, with the addition of ROHS3 compliance. Both parts share the same 330 µF capacitance, 25 V rating, ±20% tolerance, 2000-hour lifetime at 105°C, and identical lead spacing (5.00 mm) and case diameter (10.00 mm). The primary difference is product status and compliance certification.

Q: What is the difference between UVZ1E331MPD and UPW1E331MPD?

A: Both are Nichicon 330 µF, 25 V radial capacitors with identical mechanical dimensions. The key difference is lifetime: UVZ1E331MPD provides 2000 hours at 105°C, while UPW1E331MPD provides 5000 hours at 105°C. UPW1E331MPD also offers higher ripple current capability (494 mA @ 120 Hz vs. 315 mA). Select UPW1E331MPD for applications requiring extended operational life or higher ripple current handling.

Q: Why does UVZ1V331MPD have a different voltage rating?

A: UVZ1V331MPD is rated at 35 V instead of 25 V while maintaining the same 330 µF capacitance and mechanical dimensions. This higher voltage rating provides additional safety margin in circuits where the supply voltage may approach the original 25 V limit. The 35 V part is suitable for direct substitution in applications where higher voltage rating is acceptable or beneficial.

Q: Can ECA-1EHG331 be used as a substitute?

A: ECA-1EHG331 matches the electrical specifications (330 µF, 25 V, ±20% tolerance) but has different mechanical dimensions: lead spacing of 0.138" (4.60 mm) instead of 0.197" (5.00 mm), and case diameter of 0.315" (8.00 mm) instead of 0.394" (10.00 mm). This part cannot be used for direct PCB replacement without layout modification. Use only if board redesign is feasible and verified.

Q: What is the significance of AEC-Q200 certification on MAL215066331E3 and EEU-FC1E331?

A: AEC-Q200 certification indicates the part meets automotive-grade reliability and qualification standards established by the Automotive Electronics Council. These parts are suitable for automotive applications requiring higher reliability assurance. If your application does not require automotive qualification, standard industrial-grade parts are acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed carry ROHS3 compliance except the original UVZ1E331MPH, which is marked as non-compliant. ROHS3 compliance ensures the parts meet Restriction of Hazardous Substances regulations and are suitable for applications with environmental compliance requirements.

Q: What should I consider when selecting between Nichicon, Panasonic, and Vishay alternatives?

A: Selection depends on application requirements: Nichicon UPW1E331MPD offers the longest lifetime (5000 hours) for general-purpose applications. Panasonic EEU-FC1E331 provides automotive qualification (AEC-Q200) with active production status. Vishay MAL215066331E3 and MAL215056331E3 also carry AEC-Q200 certification and active production status. For new designs, prioritize parts with active production status and compliance certifications matching your application requirements.

Q: Can I use a higher capacitance value as a substitute?

A: No. Substitution is limited to parts with identical 330 µF capacitance. Higher capacitance values will alter circuit behavior and are not acceptable substitutes.

Q: What does "Not For New Designs" product status mean?

A: "Not For New Designs" indicates the manufacturer is not recommending the part for new circuit designs, though existing inventory remains available. These parts are suitable for replacement in existing applications but should not be selected for new product development. For new designs, prioritize parts with "Active" product status.
