UHD1V331MPD Equivalent & Substitute Parts

Part Overview

The UHD1V331MPD is a 330 µF, 35 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has reached end-of-life status. The UHD series offers a 4000-hour lifetime rating at 105°C with general-purpose applications. Due to its discontinued status, equivalent and substitute parts from active manufacturers or higher-reliability series are necessary for ongoing production and maintenance requirements.

Substitute Part Grouping Explanation

Substitution of the UHD1V331MPD is determined by strict equivalence across the following parameters: capacitance (330 µF), voltage rating (35 V), tolerance (±20%), polarization (polar), package type (radial can), lead spacing (5.00 mm), and diameter (10.00 mm). All substitute parts maintain identical electrical specifications and physical footprints to ensure direct replacement compatibility.

Substitute parts are grouped into three categories:

Similar Series (Nichicon): UHE1V331MPD and UHV1V331MPD offer improved lifetime ratings (7000 and 6000 hours respectively) while maintaining identical capacitance, voltage, and package dimensions. These parts are also classified as Not For New Designs.

Direct Equivalents (Active Status): ESY337M035AH2AA (KEMET) and ELXZ350ELL331MJ16S (Chemi-Con) provide equivalent electrical performance with active product status. ESY337M035AH2AA matches the 38 mOhm impedance specification exactly.

Upgraded Alternatives: 35ZLH330M10X16 (Rubycon, 10000 hours), B41858C7337M000 and B41888C7337M000 (EPCOS/TDK, automotive-rated), and 337KXM035M (Cornell Dubilier) offer extended lifetime ratings or enhanced reliability certifications while maintaining core electrical and mechanical compatibility.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): ESY337M035AH2AA provides exact electrical equivalence with 38 mOhm impedance matching and active product status, eliminating obsolescence risk. This part is the primary recommendation for new designs requiring UHD1V331MPD performance.

For Extended Reliability: 35ZLH330M10X16 (Rubycon, active status, 10000-hour lifetime) and B41888C7337M000 (EPCOS/TDK, active status, 7000-hour lifetime with AEC-Q200 automotive qualification) offer significantly extended operational life. B41888C7337M000 is suitable for applications requiring automotive-grade reliability.

For Cost-Optimized Alternatives: 35YXG330MEFC10X16 (Rubycon) and ELXZ350ELL331MJ16S (Chemi-Con, AEC-Q200 automotive-rated) provide 5000-hour lifetime ratings at lower impedance values, suitable for general-purpose applications where extended life is not critical.
