UKL1C331MPDANA Equivalent & Substitute Parts

Part Overview

The UKL1C331MPDANA is a 330 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product portfolio. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 1000 hours at 105°C, making it suitable for general-purpose applications requiring moderate voltage and capacitance ratings.

Equivalent and substitute parts are necessary when the original UKL1C331MPDANA reaches end-of-life status, inventory depletion, or when design requirements demand enhanced performance characteristics such as higher voltage ratings, extended operational lifetimes, or improved temperature stability.

Package type: Radial, Can (fixed)
Lead spacing: 0.197" (5.00 mm) (fixed)
Case diameter: 0.394" (10.00 mm) (fixed)
Polarization: Polar (fixed)

Allowable Variations:

Voltage rating: Equal to or greater than 16 V
Operating temperature range: Equal to or exceeding -40°C to 105°C
Lifetime @ temperature: Equal to or exceeding 1000 Hrs @ 105°C

Engineering Selection Recommendations

For Active Product Status: UBT1E331MPD8 and UBW1E331MPD are the only substitute parts with Active product status. UBT1E331MPD8 provides 25 V rating with 5000 hours lifetime at 125°C and extended temperature range to 125°C. UBW1E331MPD extends the upper operating temperature to 135°C with 2000 hours lifetime at that temperature, suitable for high-temperature environments.

For Voltage Margin: All substitute parts exceed the 16 V rating of the original part. 25 V rated parts (UBT1E331MPD8, UBW1E331MPD, UPM1E331MPD6, UVZ1E331MPD, UVZ1E331MPD1TD) provide single-step voltage elevation. 35 V and 50 V rated parts (UHD1V331MPD, UKA1H331MPD, UPS1V331MPD, UVY1H331MPD, UVZ1H331MPD) provide additional design margin for applications with voltage transients or future design modifications.

For Thermal Performance: UBT1E331MPD8 delivers the highest lifetime rating at 5000 hours at 125°C. UBW1E331MPD operates to 135°C, extending thermal headroom for high-ambient applications. UPM1E331MPD6 provides 5000 hours at 105°C with AEC-Q200 automotive qualification.

For Mechanical Fit: UVZ1E331MPD features reduced height of 0.492" (12.50 mm), suitable for space-constrained layouts. UVZ1E331MPD1TD offers intermediate height of 0.551" (14.00 mm) in Cut Tape packaging. All other substitutes maintain the original 0.689" (17.50 mm) height or slightly exceed it at 0.709" (18.00 mm).

For Packaging: UVZ1E331MPD1TD is supplied in Cut Tape (CT) format; all other parts are supplied in Bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can UBT1E331MPD8 or UBW1E331MPD be used as direct replacements for UKL1C331MPDANA?

A: Yes. Both parts maintain the same 330 µF capacitance, ±20% tolerance, 5.00 mm lead spacing, 10.00 mm case diameter, and through-hole radial mounting. The 25 V rating is electrically compatible with 16 V applications. UBT1E331MPD8 is Active status; UBW1E331MPD extends operating temperature to 135°C.

Q: What is the difference between 25 V, 35 V, and 50 V rated substitutes?

A: Voltage rating indicates the maximum continuous voltage the capacitor can withstand. All substitute ratings exceed the original 16 V specification, providing design margin. Higher voltage ratings typically correlate with different internal construction and thermal characteristics. Selection depends on circuit voltage requirements and available board space.

Q: Why do some substitutes have different heights?

A: UVZ1E331MPD (0.492" / 12.50 mm) and UVZ1E331MPD1TD (0.551" / 14.00 mm) are compact variants. UBT1E331MPD8 and UBW1E331MPD are slightly taller at 0.709" (18.00 mm). Height selection depends on available vertical clearance in the application. All maintain the same 10.00 mm case diameter and 5.00 mm lead spacing.

Q: What does "Not For New Designs" status mean?

A: This designation indicates the part has been superseded and Nichicon recommends using alternative models for new designs. Existing inventory may remain available, but long-term supply is not guaranteed. UBT1E331MPD8 and UBW1E331MPD carry Active status and are recommended for new designs.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original UKL1C331MPDANA.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging is supplied in loose form, suitable for manual assembly or tube feeding. Cut Tape (CT) packaging, as provided by UVZ1E331MPD1TD, is pre-cut and tape-formatted for automated pick-and-place equipment. Selection depends on assembly process requirements.

Q: Can I use a 50 V rated part in a 16 V circuit?

A: Yes. A 50 V rated capacitor is electrically compatible in a 16 V circuit. The voltage rating represents the maximum safe operating voltage; operating at lower voltages does not degrade performance. However, higher voltage ratings typically result in larger physical dimensions or different thermal characteristics, which may affect board layout.

Q: Which substitute offers the best thermal performance?

A: UBT1E331MPD8 provides 5000 hours lifetime at 125°C with extended temperature range to 125°C. UBW1E331MPD extends to 135°C operating temperature. For applications requiring AEC-Q200 automotive qualification, UPM1E331MPD6 offers 5000 hours at 105°C.
