Substitute Part Grouping Explanation

Substitution for the UPW2E3R3MPD is determined by the following critical parameters:

Capacitance Value: 3.3 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: Minimum 250 V (equal or higher acceptable)
Operating Temperature Range: -40°C ~ 105°C (must support full range)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing & Physical Dimensions: Must accommodate PCB layout constraints

Substitute parts are grouped into two categories: manufacturer-recommended alternatives with enhanced specifications, and similar alternatives from different manufacturers with equivalent electrical characteristics.

Engineering Selection Recommendations

UVZ2V3R3MPD (Manufacturer-Recommended): This Nichicon part offers a higher voltage rating of 350 V, providing additional design margin for the same 3.3 µF capacitance and ±20% tolerance. Physical dimensions and lead spacing match the original UPW2E3R3MPD exactly, ensuring direct PCB compatibility. However, the lifetime rating is reduced to 2000 hours at 105°C compared to the original 5000 hours. This part is classified as "Not For New Designs" but remains suitable for replacement applications where the enhanced voltage rating is beneficial.

EKMG251ELL3R3MHB5D (Active Alternative): Manufactured by Chemi-Con, this part maintains the 250 V rating and ±20% tolerance with 1000-hour lifetime at 105°C. The part is currently active and ROHS3 compliant. Physical dimensions differ slightly: 0.315" diameter (8.00mm) versus 0.394" (10.00mm), and lead spacing is 0.138" (4.60mm) versus 0.197" (5.00mm). PCB layout modification is required for this substitution.

SEK3R3M250ST (Active Alternative): Manufactured by Cornell Dubilier Electronics, this part matches the 250 V rating and ±20% tolerance with 2000-hour lifetime at 105°C. The part is currently active and ROHS3 compliant. Physical dimensions are 0.315" diameter (8.00mm) with 0.138" (4.60mm) lead spacing, and height is 0.433" (11.00mm). PCB layout modification is required.

UVY2E3R3MED (Similar Alternative): This Nichicon part is obsolete with reduced specifications: 1000-hour lifetime at 105°C and smaller physical dimensions (0.248" diameter, 0.098" lead spacing). This option is not recommended for new applications due to obsolete status and reduced performance metrics.

Frequently Asked Questions (FAQ)

Q: Can UVZ2V3R3MPD be used as a direct replacement for UPW2E3R3MPD?

A: Yes, with electrical compatibility noted. The UVZ2V3R3MPD has identical physical dimensions and lead spacing, allowing direct PCB mounting. The 350 V rating exceeds the original 250 V requirement. However, the lifetime is reduced from 5000 hours to 2000 hours at 105°C, which may impact long-term reliability in demanding applications.

Q: What are the PCB layout implications of using EKMG251ELL3R3MHB5D or SEK3R3M250ST?

A: Both alternatives have different lead spacing (0.138" versus 0.197") and smaller can diameters. PCB footprints must be modified to accommodate these dimensional differences. Verify that the new spacing aligns with existing trace routing and component placement constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant, matching the environmental compliance of the original UPW2E3R3MPD.

Q: Which substitute offers the best lifetime performance?

A: The UVZ2V3R3MPD provides 2000 hours at 105°C, which is superior to the 1000-hour alternatives (UVY2E3R3MED and EKMG251ELL3R3MHB5D) but lower than the original 5000-hour rating. SEK3R3M250ST also offers 2000 hours at 105°C.

Q: Can I use a substitute with a higher voltage rating in a 250 V circuit?

A: Yes. The UVZ2V3R3MPD rated at 350 V is electrically compatible with circuits designed for 250 V operation. Higher voltage ratings provide additional safety margin and do not negatively affect circuit performance.
