UFG1C331MPM1TD Equivalent & Substitute Parts

Part Overview

The UFG1C331MPM1TD is a 330 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Obsolete, indicating it is no longer in active production. The UFG series provides 1000 hours of operational life at 85°C and is designed for audio applications. Due to its obsolete status, equivalent and substitute parts with improved specifications or active production status are necessary for new designs and ongoing system support.

Substitute Part Grouping Explanation

Substitution for the UFG1C331MPM1TD is determined by the following critical parameters:

Mandatory Compatibility Parameters:

Capacitance: 330 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)
Package / Case: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)

Voltage Rating Consideration: Substitute parts must have a voltage rating equal to or greater than 16 V. Higher voltage ratings provide additional safety margin and are electrically compatible in circuits designed for 16 V operation.

Performance Enhancement Parameters: Lifetime at temperature and operating temperature range may vary. Substitutes with extended lifetime or wider temperature ranges represent performance improvements suitable for replacement.

Substitute parts are grouped into two categories: Direct Manufacturer Substitutes (same voltage rating) and Upgrade Options (higher voltage ratings or extended operational life).

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute? A: Yes. A capacitor with a voltage rating higher than 16 V is electrically compatible in circuits designed for 16 V operation. Higher voltage ratings provide additional safety margin and do not negatively affect circuit performance.

Q: What is the difference between Direct Manufacturer Substitutes and Upgrade Options? A: Direct Manufacturer Substitutes maintain the same voltage rating (16 V) as the original part. Upgrade Options feature higher voltage ratings (25 V, 35 V, or 50 V) or extended operational lifetimes and temperature ranges, providing enhanced performance characteristics.

Q: Are there mechanical compatibility concerns with substitute parts? A: All substitute parts maintain the same lead spacing of 0.197" (5.00mm) and radial can package. Most maintain the same height of 0.689" (17.50mm). UBW1E331MPD1TD has a slightly increased height of 0.709" (18.00mm), and UPM1E331MPD6TD has a reduced height of 0.669" (17.00mm). Verify PCB layout clearance before substitution.

Q: What does "Not For New Designs" product status mean? A: This designation indicates the part is no longer recommended for new circuit designs but remains available for replacement and legacy system support. For new designs, consider UBW1E331MPD1TD, which carries Active status.

Q: Which substitute offers the longest operational lifetime? A: UHE1V331MPD1TD, UPW1V331MPD1TD, and UPM1E331MPD6TD all provide 5000 to 7000-hour lifetimes at elevated temperatures. UHE1V331MPD1TD offers 7000 hours @ 105°C with a 35 V rating.

Q: Is automotive qualification available? A: UPM1E331MPD6TD carries AEC-Q200 automotive qualification and is suitable for automotive applications requiring 330 µF, 25 V capacitance with extended temperature operation.

Q: What is the impact of different operating temperature ranges? A: The original UFG1C331MPM1TD operates from -40°C to 85°C. Substitutes with extended ranges such as -55°C to 135°C (UBW1E331MPD1TD) or -55°C to 105°C (UKA1H331MPD1TD, UPS1V331MPD1TD, UPW1V331MPD1TD) provide capability for wider environmental conditions.
