Equivalent & Substitute Parts for UHD1V471MPD

Part Overview

The UHD1V471MPD is a 470 µF, 35 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 UHD series offers a 4000-hour lifetime rating at 105°C with general-purpose applications in through-hole mounting configurations. Identifying equivalent and substitute parts is necessary due to product discontinuation and the need for design continuity or component sourcing alternatives.

Substitute Part Grouping Explanation

Substitution eligibility for the UHD1V471MPD is determined by strict equivalence across the following parameters: capacitance value (470 µF), voltage rating (35 V), tolerance (±20%), lead spacing (5.00 mm), case diameter (10.00 mm), mounting type (through-hole radial), and polarization (polar). Parts are grouped into three categories based on their relationship to the main part:

Similar Manufacturer Parts (Nichicon UHE and UHV Series): These parts maintain identical electrical specifications and physical footprints but differ in lifetime ratings (ranging from 6000 to 10000 hours at 105°C) and impedance characteristics. They are direct pin-compatible replacements.

Parametric Equivalent (UHD1V471MPD1AA): This variant shares the same series designation, electrical parameters, and physical dimensions as the main part but carries Active product status, making it suitable for new designs.

Direct Equivalents (Panasonic EEU-FM1V471, Chemi-Con EKZE350ELL471MJ20S): These parts from alternative manufacturers meet all core electrical and mechanical specifications with identical lead spacing, case diameter, and height. They are functionally interchangeable.

Upgrade Options (Rubycon YXF, YXG, ZLK Series, Cornell Dubilier 477KBM035M): These parts maintain the same capacitance, voltage, tolerance, and physical footprint but offer extended lifetime ratings or improved performance characteristics. They are pin-compatible upgrades.

Engineering Selection Recommendations

For direct replacement in existing designs, UHD1V471MPD1AA is the preferred choice. It maintains identical electrical and mechanical specifications while carrying Active product status, ensuring continued availability and manufacturing support.

For new designs, EEU-FM1V471 (Panasonic) or EKZE350ELL471MJ20S (Chemi-Con) are recommended. Both are Active products with ROHS3 compliance and meet all core electrical parameters. EEU-FM1V471 offers lower impedance (19 mOhms) and extended 5000-hour lifetime. EKZE350ELL471MJ20S provides equivalent impedance to the original part with identical 4000-hour lifetime.

For applications requiring extended operational life, 477KBM035M (Cornell Dubilier) offers 7000-hour lifetime at 105°C with Active status and ROHS3 compliance. Rubycon alternatives (35YXG470MEFC10X20, 35ZLK470M10X20) provide comparable performance but carry Not For New Designs or Last Time Buy status.

All recommended substitutes maintain the 5.00 mm lead spacing and 10.00 mm case diameter, ensuring PCB footprint compatibility. Height variations (ranging from 15.00 mm to 22.00 mm) must be verified against available board clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can UHE1V471MHD6 be used as a direct replacement for UHD1V471MPD?

A: UHE1V471MHD6 shares identical capacitance, voltage, and tolerance specifications. However, it has a larger case diameter (12.50 mm versus 10.00 mm) and different height (15.00 mm versus 22.00 mm), making it unsuitable for PCB footprints designed for the original part. Lead spacing remains compatible at 5.00 mm.

Q: What is the difference between UHE1V471MPD and UHV1V471MPD?

A: Both parts maintain identical electrical specifications and physical footprints (10.00 mm diameter, 5.00 mm lead spacing). UHE1V471MPD offers 7000-hour lifetime with 46 mOhms impedance, while UHV1V471MPD provides 6000-hour lifetime with 30 mOhms impedance. Selection depends on application requirements for operational life and ripple current handling.

Q: Is EEU-FM1V471 suitable for high-ripple-current applications?

A: EEU-FM1V471 supports 2.18 A ripple current at 100 kHz with 19 mOhms impedance, exceeding the original UHD1V471MPD specification (2.05 A at 100 kHz, 23 mOhms). It is suitable for applications requiring higher ripple current capacity.

Q: Why does 477KBM035M have higher impedance than other substitutes?

A: 477KBM035M specifies 46 mOhms impedance at 120 Hz, which is higher than the original part's 23 mOhms. This characteristic does not affect basic functionality but may impact performance in high-frequency ripple current applications. Verify impedance requirements before selection.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance. REACH status varies: Nichicon and Rubycon parts are REACH Affected; Panasonic EEU-FM1V471 is REACH Unaffected; Chemi-Con EKZE350ELL471MJ20S and Cornell Dubilier 477KBM035M are REACH Unaffected.

Q: What is the significance of "Not For New Designs" status?

A: Parts marked "Not For New Designs" indicate end-of-life products with limited future availability. For new product development, select Active status alternatives such as UHD1V471MPD1AA, EEU-FM1V471, EKZE350ELL471MJ20S, or 477KBM035M to ensure long-term supply chain stability.
