Engineering Selection Recommendations

Direct Replacement (Preferred): MAL214232285E3 provides the closest electrical and mechanical compatibility with the UPW2V2R2MPD. Both parts share identical capacitance, tolerance, voltage rating, and operating temperature range. The MAL214232285E3 is manufactured by Vishay Beyschlag/Draloric/BC Components and maintains Active product status, ensuring long-term availability. Lead spacing matches at 0.197" (5.00mm), enabling direct PCB compatibility without layout modifications. The 2500-hour lifetime at 105°C exceeds the original 5000-hour specification but remains suitable for general-purpose applications.

Alternative with Voltage Margin: UVZ2W2R2MPD offers a higher voltage rating of 450 V, providing additional design margin for circuits operating near the 350 V limit. This Nichicon part maintains the same lead spacing and capacitance specifications. However, the reduced lifetime of 2000 hours at 105°C and narrower operating temperature range (-25°C ~ 105°C) require evaluation against application requirements.

Compact Footprint Options: MAL214252285E3 and MAL214272285E3 provide equivalent electrical performance with reduced lead spacing of 0.138" (4.60mm) and smaller physical dimensions. These parts are suitable for space-constrained designs where PCB layout permits the tighter pitch. Both maintain Active product status and 2500-hour lifetime ratings.

Alternative Manufacturer: SEK2R2M350ST from Cornell Dubilier Electronics provides equivalent electrical specifications with Active product status. The part features a 0.394" diameter matching the original, though with different height and lead spacing. ESR specification of 120.63 Ohm @ 120 Hz is provided for ripple current applications.

All substitute parts comply with ROHS3 and REACH requirements, matching the regulatory compliance of the original UPW2V2R2MPD.

Frequently Asked Questions (FAQ)

Q: Can UVZ2W2R2MPD be used as a direct replacement for UPW2V2R2MPD? A: UVZ2W2R2MPD shares identical capacitance, tolerance, and lead spacing specifications. The 450 V rating provides overvoltage protection compared to the 350 V original. However, the reduced lifetime of 2000 hours at 105°C versus 5000 hours, combined with a narrower operating temperature range, requires application-specific evaluation. Direct PCB compatibility is maintained.

Q: What is the difference between MAL214232285E3 and MAL214252285E3? A: Both parts are manufactured by Vishay Beyschlag/Draloric/BC Components with identical electrical specifications. The primary difference is lead spacing: MAL214232285E3 uses 0.197" (5.00mm) spacing matching the original UPW2V2R2MPD, while MAL214252285E3 uses 0.138" (4.60mm) spacing. PCB layout compatibility determines which part is appropriate for your application.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all listed substitute parts maintain ROHS3 compliance, matching the regulatory status of the original UPW2V2R2MPD. REACH compliance is also maintained across all alternatives.

Q: Why does the UPW2V2R2MPD have a longer lifetime than some substitutes? A: The original UPW2V2R2MPD specifies 5000 hours at 105°C, which is a design characteristic of the UPW series. Substitute parts from other manufacturers or series may have different thermal aging profiles. For applications requiring extended lifetime, verify that the substitute part's rated hours meet your design requirements.

Q: Can I use SEK2R2M350ST if my PCB is designed for 0.197" lead spacing? A: No. SEK2R2M350ST uses 0.138" (4.60mm) lead spacing, which is incompatible with PCB layouts designed for 0.197" (5.00mm) spacing. Use MAL214232285E3 or UVZ2W2R2MPD to maintain original lead spacing compatibility.

Q: What is the significance of the ESR specification on SEK2R2M350ST? A: The ESR (Equivalent Series Resistance) of 120.63 Ohm @ 120 Hz indicates the internal resistance of the capacitor at low frequency. This specification is relevant for ripple current applications and power supply filtering. Use this value when calculating voltage ripple or thermal dissipation in your circuit.

Q: Are there any temperature range limitations I should consider? A: UVZ2W2R2MPD has a minimum operating temperature of -25°C, compared to -40°C for the original and other substitutes. If your application requires operation below -25°C, select alternatives with -40°C minimum ratings: UPW2V2R2MPD, UVZ2V2R2MPD, MAL214232285E3, MAL214252285E3, MAL214272285E3, or SEK2R2M350ST.
