UPW2G2R2MPD Equivalent & Substitute Parts

Part Overview

The UPW2G2R2MPD is a 2.2 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is designed for general-purpose applications. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance requirements. Substitutes must maintain the same capacitance, voltage rating, and mechanical compatibility while accounting for variations in lifetime ratings and ripple current specifications.

Substitute Part Grouping Explanation

Substitution for the UPW2G2R2MPD is determined by the following mandatory parameters:

Capacitance: Must be 2.2 µF (no tolerance variation)
Voltage Rating: Must be 400 V or higher
Package Type: Must be Radial, Can
Mounting Type: Must be Through Hole
Polarization: Must be Polar
Operating Temperature Range: Must support -40°C ~ 105°C minimum
RoHS Compliance: Must be ROHS3 Compliant

Secondary parameters that may vary between substitutes include lifetime rating at 105°C, ripple current specifications, lead spacing, and physical dimensions. These variations are acceptable provided the primary parameters remain constant and the substitute part physically fits the PCB layout.

Engineering Selection Recommendations

Direct Mechanical Substitutes (Same Lead Spacing and Diameter)

UPM2G2R2MPD, UVZ2G2R2MPD, and SEK2R2M400ST maintain the same lead spacing (0.197" / 5.00mm) and diameter (0.394" / 10.00mm) as the UPW2G2R2MPD. These parts require no PCB layout modification. UPM2G2R2MPD and UVZ2G2R2MPD are Nichicon products, maintaining manufacturer consistency. SEK2R2M400ST is manufactured by Cornell Dubilier Electronics and is currently active, making it suitable for new production.

Compact Footprint Alternatives (Reduced Lead Spacing and Diameter)

UVY2G2R2MPD, EKMG401ELL2R2MHB5D, MAL214232286E3, MAL214252286E3, and MAL214272286E3 feature reduced lead spacing (0.138" / 4.60mm) and smaller diameter (0.315" / 8.00mm). These parts require PCB layout verification to confirm mechanical fit. MAL214232286E3, MAL214252286E3, and MAL214272286E3 are manufactured by Vishay Beyschlag/Draloric/BC Components and carry Active product status, making them suitable for new designs.

Higher Voltage Alternative

UVZ2W2R2MPD provides 450 V rating, exceeding the 400 V requirement. This part has reduced operating temperature range (-25°C minimum versus -40°C) and lower lifetime rating (2000 Hrs versus 5000 Hrs). Use only when higher voltage margin is required and temperature range limitation is acceptable.

Product Status Considerations

For new designs, prioritize active parts: MAL214232286E3, MAL214252286E3, MAL214272286E3, and SEK2R2M400ST. For legacy system maintenance, obsolete parts UPW2G2R2MPD, UPM2G2R2MPD, and EKMG401ELL2R2MHB5D remain available. Parts marked "Not For New Designs" (UVZ2W2R2MPD, UVY2G2R2MPD, UVZ2G2R2MPD) are suitable for replacement applications but should not be selected for new production.

Frequently Asked Questions (FAQ)

Q: Can I substitute UPW2G2R2MPD with a part having different lead spacing?

A: Yes, provided the PCB layout accommodates the new lead spacing. Verify hole positions and trace routing before implementation. Compact alternatives (0.138" lead spacing) require layout confirmation.

Q: What is the minimum voltage rating acceptable for substitution?

A: The substitute must be rated for 400 V or higher. Lower voltage ratings are not acceptable as they reduce safety margin and circuit reliability.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All parts in this reference meet ROHS3 compliance requirements.

Q: Does lifetime rating affect substitution suitability?

A: Lifetime rating is a secondary parameter. Lower lifetime ratings (1000 Hrs, 2000 Hrs) are acceptable substitutes for the original 5000 Hrs rating if application duty cycle permits. Higher lifetime ratings provide extended service life.

Q: Can I use UVZ2W2R2MPD as a direct replacement?

A: UVZ2W2R2MPD has a reduced operating temperature minimum (-25°C versus -40°C) and lower lifetime (2000 Hrs versus 5000 Hrs). Use only if the application does not require -40°C operation and the reduced lifetime is acceptable.

Q: Which substitute is best for new production?

A: SEK2R2M400ST (Cornell Dubilier), MAL214232286E3, MAL214252286E3, or MAL214272286E3 (Vishay) are active products suitable for new designs. Select based on required lead spacing and mechanical fit.

Q: Are there any cross-manufacturer compatibility issues?

A: No. All substitutes meet the same electrical and mechanical specifications. Cross-manufacturer substitution is valid provided all primary parameters match.
