Nichicon UPS2D331MRD Equivalent & Substitute Parts

Part Overview

The Nichicon UPS2D331MRD is a 330 µF, 200 V aluminum electrolytic capacitor in radial, can package rated for 3000 hours at 105°C. This part is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active product lines are necessary for new designs and ongoing production requirements. Substitute parts maintain the same electrical specifications (capacitance, voltage rating, tolerance, and operating temperature range) while offering improved reliability through extended lifetime ratings or alternative packaging configurations.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 200 V (exact match required)
Tolerance: ±20% (exact match required)
Operating Temperature Range: -40°C to 105°C (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

All substitute parts listed maintain these core electrical and mechanical parameters. Variations in lifetime ratings, ripple current specifications, physical dimensions, and lead spacing are secondary characteristics that do not disqualify substitution but may affect circuit performance in specific applications.

Engineering Selection Recommendations

Direct Substitutes (Nichicon UPS Series Replacement)

UPW2D331MRD is the direct Nichicon equivalent, maintaining identical lead spacing (10.00mm) and similar physical dimensions to the UPS2D331MRD. This part offers extended lifetime (8000 hours at 105°C) while retaining obsolete product status. Selection is appropriate for designs requiring minimal PCB layout modification.

Active Product Line Alternatives

For new designs, active product status parts are preferred:

UCS2D331MHD provides 10000-hour lifetime with compact dimensions (18.00mm diameter, 37.00mm height) and active product status. This part offers superior reliability for long-term applications.
UCY2D331MHD and UCY2D331MHD6 deliver the highest lifetime rating (12000 hours at 105°C) with active product status. UCY2D331MHD6 offers the most compact height (33.00mm) among active alternatives.
EKXG201ELL331MMP1S (Chemi-Con KXG series) provides 10000-hour lifetime with active status and ROHS3 compliance, offering cross-manufacturer compatibility.

Compact Form Factor Option

LDQ2D331MERYGA provides the smallest physical footprint (20.00mm diameter, 20.00mm height) with active product status, suitable for space-constrained applications. Lifetime rating is 2000 hours at 105°C.

Not Recommended for New Designs

UVY2D331MHD carries "Not For New Designs" status and should be avoided in new development despite electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use UCS2D331MHD as a direct replacement for UPS2D331MRD?

A: Yes. Both parts share identical electrical specifications (330 µF, 200 V, ±20%, -40°C to 105°C). UCS2D331MHD is physically smaller (18.00mm diameter vs. 22.00mm, 37.00mm height vs. 42.00mm) and has different lead spacing (7.50mm vs. 10.00mm). PCB layout modification is required. UCS2D331MHD offers superior reliability with 10000-hour lifetime and active product status.

Q: What is the difference between UCY2D331MHD and UCY2D331MHD6?

A: Both are Nichicon UCY series parts with identical electrical specifications and 12000-hour lifetime at 105°C. UCY2D331MHD has 41.50mm height, while UCY2D331MHD6 has 33.00mm height. Lead spacing is identical (7.50mm). Selection depends on available vertical space in the PCB layout.

Q: Is EKXG201ELL331MMP1S compatible with UPS2D331MRD?

A: Yes. The Chemi-Con EKXG201ELL331MMP1S maintains all required electrical parameters (330 µF, 200 V, ±20%, -40°C to 105°C). Physical dimensions differ (18.00mm diameter, 35.50mm height, 7.50mm lead spacing). PCB layout modification is required. This part offers 10000-hour lifetime and active product status.

Q: Why do substitute parts have different physical dimensions?

A: Capacitor manufacturers optimize physical design across product series. Smaller diameter and height typically correlate with improved ripple current handling and extended lifetime ratings. Dimension variations require PCB layout verification but do not affect electrical compatibility when core parameters match.

Q: Which substitute part should I select for maximum reliability?

A: UCY2D331MHD and UCY2D331MHD6 offer the highest lifetime rating (12000 hours at 105°C) with active product status. Selection between these two depends on available vertical PCB space.

Q: Are all listed parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification.
