Engineering Selection Recommendations

For Active Product Status: UBT1E331MPD8 and UBW1E331MPD are the only active alternatives. UBT1E331MPD8 provides 5000 hours lifetime at 125°C with extended operating range (-40°C ~ 125°C). UBW1E331MPD extends the upper operating temperature to 135°C with 2000 hours lifetime at that temperature. Both are rated 25 V, providing voltage margin above the original 16 V specification.

For Voltage-Matched Substitution (16 V): UKL1C331MPDANA and UKL1C331KPDANA maintain the 16 V rating with improved lifetime specifications (1000 Hrs @ 105°C versus 1000 Hrs @ 85°C). UKL1C331KPDANA offers tighter tolerance (±10% versus ±20%). Both are classified as Not For New Designs.

For Higher Voltage Ratings: 25 V, 35 V, and 50 V alternatives are electrically compatible in circuits where the original 16 V rating provides sufficient margin. These options offer extended operating temperature ranges and improved lifetime ratings suitable for demanding applications.

Compliance Consideration: All substitute parts maintain ROHS3 compliance and are manufactured by Nichicon, ensuring consistency with the original component's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated capacitor in place of the 16 V UFG1C331MPM? A: Yes. Higher voltage ratings are electrically compatible in circuits designed for the original 16 V component. The 25 V alternatives provide voltage margin and typically offer extended lifetime specifications. Physical dimensions and lead spacing remain identical.

Q: What is the difference between UBT1E331MPD8 and UBW1E331MPD? A: Both are 330 µF, 25 V alternatives with identical physical dimensions. UBT1E331MPD8 provides 5000 hours lifetime at 125°C with operating range -40°C ~ 125°C. UBW1E331MPD provides 2000 hours lifetime at 135°C with extended lower temperature limit (-55°C ~ 135°C). Selection depends on the specific thermal environment of the application.

Q: Are the 50 V rated alternatives physically compatible? A: Yes. UKA1H331MPD, UVR1H331MPD, and UVY1H331MPD maintain the same lead spacing (0.197" / 5.00 mm), package type (Radial, Can), and mounting configuration (Through Hole) as the original UFG1C331MPM. Height dimensions are identical at 0.689" (17.50 mm).

Q: Why is the UFG1C331MPM listed as obsolete? A: Obsolete status indicates the part is no longer manufactured. Substitute parts with active or Not For New Designs status provide continued availability and often include improved specifications such as extended lifetime ratings and wider operating temperature ranges.

Q: What tolerance options are available? A: The original UFG1C331MPM specifies ±20% tolerance. Substitute parts maintain ±20% tolerance, with UKL1C331KPDANA offering tighter ±10% tolerance for applications requiring higher capacitance accuracy.

Q: Do all substitutes maintain ROHS3 compliance? A: Yes. All listed substitute parts are ROHS3 compliant, matching the regulatory status of the original component.
