Equivalent & Substitute Parts for UVY1E331MPD1TD

Part Overview

The UVY1E331MPD1TD is a 330 µF, 25 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has reached end-of-life status. The UVY series offers a 1000-hour lifetime rating at 105°C and is suitable for general-purpose applications requiring through-hole mounting.

Due to its discontinued status, equivalent and substitute parts are necessary for ongoing maintenance, repair, and legacy system support. Available alternatives include upgraded Nichicon series with extended lifetimes, direct equivalents from other manufacturers, and parametrically compatible options.

Substitute Part Grouping Explanation

Substitution eligibility for the UVY1E331MPD1TD is determined by the following critical parameters:

Capacitance Value: 330 µF (exact match required)
Voltage Rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.138" (4.60 mm) (exact match required)
Case Diameter: 0.315" (8.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Configuration: Radial, Can (exact match required)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in lifetime rating, ripple current handling, and product status are secondary considerations that do not affect basic functional compatibility.

Engineering Selection Recommendations

UPA1E331MPD1TD (Nichicon) is the preferred substitute for new applications and ongoing designs. This part carries Active product status and offers the highest lifetime rating at 3000 hours @ 105°C, providing extended operational reliability. It maintains identical electrical and mechanical specifications to the original UVY1E331MPD1TD while offering superior performance characteristics.

UKA1E331MPD1TD (Nichicon) serves as an intermediate upgrade option with 2000-hour lifetime rating. While classified as Not For New Designs, it provides a direct upgrade path within the Nichicon product family with improved reliability over the original UVY series.

ECA-1EHG331BJ (Panasonic Electronic Components) is a direct equivalent from an alternative manufacturer with Active product status. This part includes AEC-Q200 automotive qualification and is suitable for applications requiring third-party sourcing or supply chain diversification. Height dimension is 0.492" (12.50 mm) compared to 0.512" (13.00 mm) for other options; verify clearance in confined mounting spaces.

EKMG250ETD331MHB5D (Chemi-Con) provides parametric equivalence with Active product status. Packaging is supplied as Tape & Box (TB) rather than Cut Tape (CT); confirm packaging requirements for assembly processes.

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

Frequently Asked Questions (FAQ)

Q: Can UPA1E331MPD1TD be used as a direct replacement for UVY1E331MPD1TD?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), lead spacing (0.138"), case diameter (0.315"), and mounting configuration (through-hole radial). The UPA1E331MPD1TD offers extended lifetime (3000 hours vs. 1000 hours @ 105°C) and carries Active product status.

Q: What is the significance of the height difference between ECA-1EHG331BJ and other substitutes?

A: The ECA-1EHG331BJ has a maximum seated height of 0.492" (12.50 mm) compared to 0.512" (13.00 mm) for UVY1E331MPD1TD and most alternatives. This 0.020" (0.50 mm) difference is negligible for most applications but should be verified if the capacitor is mounted in a space-constrained environment or near components with tight vertical clearance.

Q: Are there differences in ripple current handling between substitutes?

A: Yes. Ripple current ratings vary among substitutes. UPA1E331MPD1TD provides the highest ripple current at 409.5 mA @ 120 Hz. ECA-1EHG331BJ and EKMG250ETD331MHB5D both support 310 mA @ 120 Hz. Select based on application ripple current requirements; higher ratings provide additional margin for high-frequency switching applications.

Q: What packaging format differences exist?

A: UVY1E331MPD1TD, UKA1E331MPD1TD, UPA1E331MPD1TD, and ECA-1EHG331BJ are supplied in Cut Tape (CT) packaging. EKMG250ETD331MHB5D is supplied in Tape & Box (TB) format. Confirm packaging compatibility with assembly equipment and procurement workflows.

Q: Which substitute is recommended for automotive applications?

A: ECA-1EHG331BJ carries AEC-Q200 automotive qualification and Active product status, making it the designated choice for automotive-grade requirements. Other substitutes lack explicit automotive certification.

Q: Is the UVY1E331MPD1TD still available for purchase?

A: The UVY1E331MPD1TD is classified as Not For New Designs. While 1438 pieces are listed as in stock, this represents legacy inventory. For new designs and long-term supply assurance, transition to UPA1E331MPD1TD or alternative active-status parts.
