UPW2G3R3MPD Equivalent & Substitute Parts

Part Overview

The UPW2G3R3MPD is a 3.3 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 5000 hours at 105°C, serving general-purpose applications requiring stable capacitance and reliable performance in through-hole mounting configurations.

Substitute Part Grouping Explanation

Substitution eligibility for the UPW2G3R3MPD is determined by strict equivalence across the following parameters: capacitance (3.3 µF), voltage rating (400 V), tolerance (±20%), polarization (polar), package type (radial, can), and mounting type (through hole). Lead spacing and physical dimensions are critical for PCB compatibility. All substitute parts must maintain ROHS3 compliance and operate within the specified temperature range of -40°C to 105°C.

The substitute parts are grouped as follows:

Manufacturer-Recommended Substitute: UVZ2G3R3MPD (Nichicon) — Direct electrical equivalent with reduced lifetime specification (2000 hours at 105°C versus 5000 hours).

Similar Alternatives: UVY2G3R3MPD (Nichicon), EKMG401ELL3R3MJC5S (Chemi-Con), and SEK3R3M400ST (Cornell Dubilier Electronics) — Functionally equivalent with variations in lifetime, ripple current ratings, and physical dimensions.

Engineering Selection Recommendations

For Direct PCB Replacement (Preferred): UVZ2G3R3MPD or EKMG401ELL3R3MJC5S are suitable direct substitutes, maintaining identical lead spacing (0.197" / 5.00mm) and similar physical dimensions. UVZ2G3R3MPD is the manufacturer-recommended alternative from Nichicon. EKMG401ELL3R3MJC5S, manufactured by Chemi-Con, carries active product status and full ROHS3 compliance.

For New Designs: EKMG401ELL3R3MJC5S and SEK3R3M400ST are preferred selections due to active product status. Both maintain full electrical equivalence and regulatory compliance.

For Space-Constrained Applications: UVY2G3R3MPD offers reduced physical dimensions (0.315" diameter, 8.00mm) but requires PCB layout modification due to different lead spacing (0.138" / 4.60mm). This part is classified as not for new designs.

Lifetime Considerations: The original UPW2G3R3MPD specifies 5000 hours at 105°C. Substitute parts offer reduced lifetimes (1000 to 2000 hours). Applications requiring extended operational life at elevated temperatures should evaluate this parameter against system requirements.

Frequently Asked Questions (FAQ)

Q: Can UVY2G3R3MPD be used as a direct replacement for UPW2G3R3MPD?

A: UVY2G3R3MPD is electrically equivalent but not a direct PCB replacement. The lead spacing differs (0.138" versus 0.197"), and physical dimensions are smaller. PCB layout modification is required.

Q: What is the primary difference between UVZ2G3R3MPD and EKMG401ELL3R3MJC5S?

A: Both are electrically equivalent with identical lead spacing and similar dimensions. UVZ2G3R3MPD is manufactured by Nichicon (not for new designs), while EKMG401ELL3R3MJC5S is manufactured by Chemi-Con with active product status. EKMG401ELL3R3MJC5S is recommended for new designs.

Q: Does SEK3R3M400ST meet the same specifications as the original part?

A: SEK3R3M400ST is electrically equivalent with identical lead spacing and voltage rating. It specifies 2000 hours lifetime at 105°C (versus 5000 hours for the original) and carries active product status with full ROHS3 compliance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original UPW2G3R3MPD.

Q: What should be considered when selecting between substitute parts?

A: Primary considerations are product status (active versus not for new designs), manufacturer availability, PCB layout compatibility (lead spacing and dimensions), and lifetime requirements at operating temperature. For new designs, EKMG401ELL3R3MJC5S or SEK3R3M400ST are preferred due to active status.
