Equivalent & Substitute Parts for UTT1C471MPD

Part Overview

The UTT1C471MPD is a 470 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing applications. The original part features a 5000-hour lifetime rating at 105°C and is suitable for general-purpose applications requiring through-hole mounting with 4.60 mm lead spacing.

Substitute Part Grouping Explanation

Substitution of the UTT1C471MPD is determined by strict equivalence in the following parameters: capacitance value (470 µF), voltage rating (16 V), tolerance (±20%), and mounting configuration (through-hole radial). Physical dimensions, particularly lead spacing and case diameter, are critical for PCB compatibility. Lifetime ratings and ripple current specifications vary among substitutes and must be evaluated against application requirements. All identified substitutes maintain ROHS3 compliance and the same electrical ratings as the original part.

Substitutes are grouped into two categories: Nichicon series alternatives (UPW, UHD, UHE, UHV) and Panasonic FM-A series alternatives (EEU-FM). Within each manufacturer's lineup, variants differ in lifetime ratings, impedance characteristics, and physical dimensions while maintaining core electrical specifications.

Engineering Selection Recommendations

For direct PCB replacement with identical lead spacing (0.138" / 4.60 mm) and case diameter (0.315" / 8.00 mm), select from: UPW1C471MPD6, UHD1C471MPD, UHE1C471MPD, UHV1C471MPD, or EEU-FM1C471L. These maintain the original footprint while offering improved or equivalent performance characteristics.

UHV1C471MPD provides the closest performance match to the original UTT1C471MPD, with 6000-hour lifetime at 105°C and reduced impedance (59 mOhms versus 400 mOhms), while maintaining identical lead spacing and case diameter.

For applications where PCB layout permits larger case dimensions (0.394" / 10.00 mm diameter), UHD1C471MPD6, UHE1C471MPD6, EEU-FM1C471, and EEU-FM1C471B offer superior electrical performance with lower impedance and extended lifetime ratings.

Panasonic FM-A series parts (EEU-FM1C471, EEU-FM1C471B, EEU-FM1C471L, EEU-FM1C471LB) are currently in active production status, providing long-term supply continuity. All Nichicon alternatives carry "Not For New Designs" status.

Frequently Asked Questions (FAQ)

Q: Can UHD1C471MPD6 replace UTT1C471MPD directly on the PCB?

A: UHD1C471MPD6 has different lead spacing (0.197" versus 0.138") and case diameter (0.394" versus 0.315"), requiring PCB layout modification. For direct replacement without layout changes, use UHV1C471MPD or EEU-FM1C471L.

Q: What is the difference between EEU-FM1C471 and EEU-FM1C471B?

A: Both parts are electrically identical with 470 µF capacitance, 16 V rating, and 4000-hour lifetime. The primary difference is packaging: EEU-FM1C471 is supplied in bulk, while EEU-FM1C471B is supplied in cut tape format.

Q: Why do some substitutes have lower impedance than the original?

A: Impedance variation reflects differences in internal construction and manufacturing series. Lower impedance generally indicates improved high-frequency performance and reduced ripple current stress, which is beneficial for most applications.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance, matching the original UTT1C471MPD specification.

Q: Which substitute offers the longest operational lifetime?

A: UHE1C471MPD and UHE1C471MPD6 provide 7000-hour lifetime at 105°C, the highest among all listed alternatives.

Q: Can I use EEU-FM1C471LB if my PCB has 0.138" lead spacing?

A: No. EEU-FM1C471LB has 0.197" lead spacing. For 0.138" spacing compatibility, use EEU-FM1C471L instead.
