Equivalent & Substitute Parts for UPW2D3R3MPD

Part Overview

The UPW2D3R3MPD is a 3.3 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement. The UPW series has been superseded by newer product lines while maintaining the same core electrical specifications for general-purpose applications.

Substitute Part Grouping Explanation

Substitution for the UPW2D3R3MPD is determined by the following critical parameters: capacitance value (3.3 µF), tolerance (±20%), voltage rating (200 V minimum), polarization (polar), mounting type (through hole radial), and physical compatibility with the specified lead spacing and case dimensions.

The substitute parts are grouped into two categories:

Manufacturer Recommended Substitute (Higher Voltage Rating): UVY2V3R3MPD maintains identical capacitance, tolerance, and operating temperature range but features a higher voltage rating (350 V) and different physical dimensions. This part is suitable where voltage headroom is required and PCB layout accommodates the increased height.

Similar Manufacturer Substitutes (Same Voltage Rating): UVZ2D3R3MED and SEK3R3M200ST both maintain the 200 V voltage specification and 3.3 µF capacitance. These parts differ in physical dimensions, lead spacing, and lifetime ratings, requiring verification of PCB layout compatibility.

Engineering Selection Recommendations

UVY2V3R3MPD (Nichicon): This manufacturer-recommended substitute provides higher voltage rating (350 V) with identical lead spacing (4.60mm) and similar case diameter (8.00mm). The increased height (13.00mm vs. 11.50mm) requires PCB layout verification. Product status is "Not For New Designs," indicating limited long-term availability. Suitable for applications requiring voltage margin above 200 V specification.

UVZ2D3R3MED (Nichicon): This part maintains 200 V voltage rating and Nichicon manufacturing continuity. However, reduced lead spacing (2.50mm vs. 4.60mm) and smaller case diameter (6.30mm vs. 8.00mm) necessitate PCB footprint redesign. Obsolete status limits procurement viability.

SEK3R3M200ST (Cornell Dubilier Electronics): This part is the only active product among the substitutes, offering 200 V rating with 2000 Hrs @ 105°C lifetime. Lead spacing (2.50mm) and case diameter (6.30mm) differ from the original, requiring PCB layout modification. Active product status provides superior long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can UVY2V3R3MPD be used as a direct replacement for UPW2D3R3MPD?

A: UVY2V3R3MPD shares identical capacitance, tolerance, and lead spacing (4.60mm), enabling direct PCB footprint compatibility. The increased height (13.00mm vs. 11.50mm) must be verified against available board space. The higher voltage rating (350 V) is electrically compatible with 200 V applications.

Q: What are the physical compatibility constraints for UVZ2D3R3MED and SEK3R3M200ST?

A: Both parts feature reduced lead spacing (2.50mm vs. 4.60mm) and smaller case diameter (6.30mm vs. 8.00mm). These dimensions require PCB footprint redesign and cannot be used as direct drop-in replacements without layout modification.

Q: How does product status affect substitution decisions?

A: UPW2D3R3MPD and UVZ2D3R3MED are obsolete, indicating discontinued manufacturing and limited stock availability. UVY2V3R3MPD is "Not For New Designs," suggesting phase-out. SEK3R3M200ST maintains active status, providing the most reliable long-term supply chain and manufacturing support.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts (UVY2V3R3MPD, UVZ2D3R3MED, and SEK3R3M200ST) are ROHS3 compliant, maintaining environmental and regulatory compatibility with the original UPW2D3R3MPD.

Q: What is the significance of lifetime rating differences?

A: The original UPW2D3R3MPD specifies 3000 Hrs @ 105°C. UVY2V3R3MPD and UVZ2D3R3MED offer 1000 Hrs @ 105°C, while SEK3R3M200ST provides 2000 Hrs @ 105°C. Applications requiring extended thermal life should prioritize SEK3R3M200ST or verify that reduced lifetime meets system requirements.
