UHV1V331MPD Equivalent & Substitute Parts

Part Overview

The UHV1V331MPD is a 330 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 6000 hours at 105°C and is classified as Not For New Designs. Due to this product status and the availability of higher-reliability alternatives with extended operational lifetimes, equivalent and substitute parts are necessary for ongoing maintenance, repair, and legacy system support.

Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Diameter: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)

Substitute parts are grouped into two categories:

Similar Performance Substitutes: Parts with identical electrical and mechanical specifications but different manufacturers or series designations. These maintain equivalent functionality with variations in lifetime ratings and ripple current handling.

Upgraded Performance Substitutes: Parts with identical core specifications but extended lifetime ratings (10000 hours at 105°C) and active product status, offering improved reliability for new applications and long-term deployments.

Engineering Selection Recommendations

For Direct Replacement (Same Footprint and Height):

Use 35ZLH330MEFC10X12.5 (Rubycon, Active status) or EKYB350ELL331MJC5S (Chemi-Con, Active status). Both maintain the 0.551" (14.00 mm) height of the original UHV1V331MPD and offer 10000-hour lifetime at 105°C with active product status, providing superior long-term reliability.

For Space-Constrained Applications:

The 35YXJ330M10X12.5 (Rubycon, Active status) matches the original height and footprint exactly while delivering 10000-hour lifetime performance.

For Active Product Status with Standard Height:

EEU-FM1V331, EEU-FM1V331B (Panasonic, Bulk and Cut Tape packaging) are active products with 4000-hour lifetime. These are suitable for applications where extended height (0.689") is acceptable.

For Extended Height Tolerance:

EEU-FM1V331L, EEU-FM1V331LB, EEU-FM1V331LBJ (Panasonic, Active status) provide 4000-hour lifetime with reduced impedance (30 mOhms) but require 0.866" (22.00 mm) clearance.

All substitute parts listed are ROHS3 compliant and maintain the required electrical specifications for direct functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can UHD1V331MPD be used as a direct replacement for UHV1V331MPD?

A: UHD1V331MPD meets all core electrical and mechanical specifications (330 µF, 35 V, ±20%, radial can, 5.00 mm lead spacing, 10.00 mm diameter, through-hole mounting). However, it has a taller profile (0.689" vs. 0.551") and lower lifetime rating (4000 hours vs. 6000 hours). Verify PCB clearance before substitution.

Q: What is the difference between the Nichicon UHV, UHD, and UHE series?

A: All three series share identical electrical specifications (330 µF, 35 V, ±20%). The primary differences are lifetime ratings (UHV: 6000 hrs, UHD: 4000 hrs, UHE: 7000 hrs) and physical height (UHV: 14.00 mm, UHD: 17.50 mm, UHE: 16.00 mm). All are classified as Not For New Designs.

Q: Are the Panasonic EEU-FM1V331 variants interchangeable?

A: EEU-FM1V331, EEU-FM1V331B, and EEU-FM1V331LB share identical electrical specifications but differ in packaging (Bulk vs. Cut Tape) and physical dimensions. EEU-FM1V331L and variants have different lead spacing (4.60 mm vs. 5.00 mm) and height (22.00 mm), making them incompatible with the original 5.00 mm lead spacing requirement.

Q: Why should I choose an upgraded part with 10000-hour lifetime?

A: Upgraded parts (35YXJ330M10X12.5, 35ZLH330MEFC10X12.5, EKYB350ELL331MJC5S) have active product status and extended operational lifetime, reducing field failure risk and supporting longer system lifecycles. They maintain identical footprints and electrical performance.

Q: What does "Not For New Designs" mean for the original UHV1V331MPD?

A: This designation indicates the part is in mature or end-of-life status and should not be selected for new product development. Existing systems using this part may continue operation, but substitution with active-status alternatives is recommended for maintenance and repair applications.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All substitute parts listed meet ROHS3 compliance requirements, ensuring compatibility with environmental and regulatory standards.

Q: What is the significance of impedance differences among substitutes?

A: Impedance values (ranging from 26 mOhms to 80 mOhms) reflect internal resistance characteristics. Lower impedance generally indicates better high-frequency ripple current handling. The original UHV1V331MPD has 43 mOhms impedance. Substitutes with lower impedance (EEU-FM series at 26-30 mOhms) provide improved performance; higher impedance (80 mOhms for 35YXJ330M10X12.5) may require verification for ripple current applications.

Q: Can I use parts with different heights if my PCB has clearance?

A: Yes, provided the lead spacing (5.00 mm), diameter (10.00 mm), and all electrical specifications remain identical. Verify mechanical clearance and confirm no height-dependent mechanical constraints exist in your assembly.
