Substitute Part Grouping Explanation

Substitution eligibility for the UPW2V3R3MPD is determined by the following critical parameters:

Capacitance: 3.3 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage - Rated: 350 V minimum (equal or higher voltage acceptable)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required for through-hole compatibility)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Substitutes: Parts from the same manufacturer (Nichicon) with identical electrical specifications but potentially different lifetime ratings or physical dimensions within acceptable tolerances.

Manufacturer Recommended Substitutes: Parts with higher voltage ratings (400 V vs. 350 V) that provide enhanced electrical margin while maintaining all other critical parameters.

Similar Manufacturer Substitutes: Parts from alternative manufacturers (Chemi-Con, Cornell Dubilier Electronics) meeting the core electrical and mechanical specifications, with variations in ripple current handling and lifetime characteristics.

Engineering Selection Recommendations

Direct Nichicon Substitutes (UVZ2V3R3MPD, UVZ2G3R3MPD): These parts maintain Nichicon series continuity and are suitable for applications where the original UPW2V3R3MPD is no longer available. UVZ2V3R3MPD provides identical electrical specifications with reduced lifetime (2000 hours vs. 5000 hours). UVZ2G3R3MPD offers higher voltage rating (400 V) with the same reduced lifetime, providing additional electrical margin. Both are marked "Not For New Designs" and should be used only for legacy system support or replacement applications.

Chemi-Con EKMG351ELL3R3MJC5S: This part is actively manufactured and meets all core electrical and mechanical requirements. It provides an alternative source from a qualified manufacturer with ROHS3 compliance. The 1000-hour lifetime is lower than the original specification but acceptable for general-purpose applications. This part is suitable for new designs requiring a 3.3 µF 350 V radial capacitor.

Cornell Dubilier Electronics SEK3R3M350ST: This part is actively manufactured and provides equivalent electrical performance with 2000-hour lifetime at 105°C. It offers higher ripple current capability (47 mA @ 120 Hz, 84.6 mA @ 10 kHz) compared to the original specification. This part is suitable for applications requiring enhanced ripple current handling and is recommended for new designs.

UVY2V3R3MPD Limitation: This part has different lead spacing (0.138" vs. 0.197") and smaller physical dimensions, making it mechanically incompatible with the original UPW2V3R3MPD footprint. This part is not recommended as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can UVZ2V3R3MPD be used as a direct replacement for UPW2V3R3MPD?

A: UVZ2V3R3MPD is electrically compatible with identical capacitance, tolerance, voltage rating, and lead spacing. However, the lifetime rating is reduced from 5000 hours to 2000 hours at 105°C. This substitution is acceptable for applications where the reduced lifetime does not impact system reliability requirements.

Q: What is the difference between UVZ2V3R3MPD and UVZ2G3R3MPD?

A: Both parts are from the Nichicon UVZ series with identical lifetime (2000 hours @ 105°C) and physical dimensions. The primary difference is voltage rating: UVZ2V3R3MPD is rated 350 V, while UVZ2G3R3MPD is rated 400 V. The 400 V rating provides additional electrical margin and is suitable for applications with higher voltage transients or design safety requirements.

Q: Why is UVY2V3R3MPD not recommended as a substitute?

A: UVY2V3R3MPD has different lead spacing (0.138" vs. 0.197") and smaller physical dimensions (0.315" diameter vs. 0.394" diameter). These mechanical differences make it incompatible with PCB layouts designed for the UPW2V3R3MPD footprint. Additionally, it has reduced ripple current capability and shorter lifetime (1000 hours).

Q: Is EKMG351ELL3R3MJC5S suitable for new designs?

A: Yes. EKMG351ELL3R3MJC5S is actively manufactured by Chemi-Con and meets all core electrical specifications (3.3 µF, ±20%, 350 V, polar, radial can package). It is ROHS3 compliant and suitable for new designs requiring a 3.3 µF 350 V aluminum electrolytic capacitor. The 1000-hour lifetime is lower than the original UPW2V3R3MPD but is standard for this capacitor category.

Q: What are the advantages of SEK3R3M350ST?

A: SEK3R3M350ST is actively manufactured by Cornell Dubilier Electronics and offers higher ripple current capability (47 mA @ 120 Hz) compared to the original specification (38 mA @ 120 Hz). It provides 2000-hour lifetime at 105°C and is ROHS3 compliant. This part is recommended for applications requiring enhanced ripple current handling or where Cornell Dubilier sourcing is preferred.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original UPW2V3R3MPD.

Q: Can I use a 400 V rated capacitor in place of a 350 V rated capacitor?

A: Yes. Higher voltage-rated capacitors are electrically compatible with lower voltage applications. UVZ2G3R3MPD (400 V) can be used in applications designed for UPW2V3R3MPD (350 V) without electrical issues. The higher voltage rating provides additional safety margin and is acceptable for direct substitution.
