Equivalent & Substitute Parts for UVZ1V331MPD1TD

Part Overview

The UVZ1V331MPD1TD is a 330 µF, 35 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 2000 hours at 105°C and is classified as Not For New Designs. Due to its discontinued design status, equivalent and substitute parts from active product lines are available to maintain circuit functionality and ensure long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the UVZ1V331MPD1TD is determined by strict equivalence across the following parameters: capacitance value (330 µF), voltage rating (35 V), tolerance (±20%), lead spacing (5.00 mm), package diameter (10.00 mm), mounting type (through hole radial), and ripple current capability at low frequency (350 mA @ 120 Hz). All substitute parts maintain these core electrical and mechanical specifications. Lifetime ratings at 105°C may vary between 1000 and 2000 hours; parts with 2000-hour ratings provide extended operational life. Product status differentiation identifies active components suitable for new designs versus legacy parts approaching end-of-life.

Engineering Selection Recommendations

For applications requiring immediate component replacement with extended operational life, EEU-HD1V331B (Panasonic) and ECA-1VHG331B (Panasonic) are preferred selections. Both parts carry Active product status, maintain 2000-hour lifetime ratings at 105°C, and hold current ROHS3 compliance certifications. These components ensure supply chain continuity and support long-term system reliability.

URZ1V331MPD1TD (Nichicon) and EKMG350EC3331MJC5S (Chemi-Con) provide Active product alternatives with 1000-hour lifetime ratings. These parts are suitable for applications where reduced operational life is acceptable or where cost optimization is a design priority.

UVY1V331MPD1TD and UKA1V331MPD1TD remain functionally equivalent to the original UVZ1V331MPD1TD but carry Not For New Designs status, limiting their use to legacy system maintenance and repair applications.

Frequently Asked Questions (FAQ)

Q: Can URZ1V331MPD1TD replace UVZ1V331MPD1TD in all applications?

A: URZ1V331MPD1TD maintains identical electrical and mechanical specifications with one exception: lifetime rating is 1000 hours at 105°C versus 2000 hours for the original part. Substitution is valid for applications where the reduced operational life does not compromise system requirements.

Q: What is the height difference between ECA-1VHG331B and other substitute parts?

A: ECA-1VHG331B has a seated height of 14.60 mm, while most other substitutes measure 14.00 mm. This 0.50 mm difference must be verified against PCB layout constraints and clearance requirements before implementation.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed carry ROHS3 compliance certification. All parts are REACH Unaffected and classified under ECCN EAR99.

Q: What is the difference between EKMG350EC3331MJC5S and EKMG350ETD331MJC5S?

A: Both parts are manufactured by Chemi-Con with identical electrical specifications. The primary difference is packaging: EKMG350EC3331MJC5S is supplied in Tape & Box (TB) format, while EKMG350ETD331MJC5S is supplied in Cut Tape (CT) format.

Q: Which substitute part offers the best long-term reliability?

A: EEU-HD1V331B and ECA-1VHG331B both provide 2000-hour lifetime ratings at 105°C with Active product status, offering equivalent long-term reliability to the original UVZ1V331MPD1TD.
