Equivalent & Substitute Parts for UTT1E331MPD1TA

Part Overview

The UTT1E331MPD1TA is a 330 µF, 25 V aluminum electrolytic capacitor manufactured by Nichicon in the UTT series. This radial, through-hole component is rated for 5000 hours at 105°C and is designed for general-purpose applications requiring reliable energy storage and filtering. The part is currently active in production with full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, lead time considerations, or application-specific performance needs.

Substitute Part Grouping Explanation

Substitution eligibility for the UTT1E331MPD1TA is determined by strict equivalence in the following parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating temperature range: -40°C to 105°C (minimum requirement)
• Lead spacing: 0.138" (4.60 mm) (exact match required for PCB compatibility)
• Case diameter: 0.315" (8.00 mm) (exact match required for mechanical fit)
• Height: 0.512" (13.00 mm) (exact match required for mechanical fit)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Polarization: Polar (exact match required)

The substitute part 25ZLH330MEFCT78X11.5 manufactured by Rubycon meets all these criteria. Additional performance characteristics such as ripple current ratings and lifetime at temperature may vary within acceptable ranges for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both the UTT1E331MPD1TA and 25ZLH330MEFCT78X11.5 are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• PCB layout and assembly schedule requirements
• Inventory availability and lead time
• Application thermal environment and expected operational lifetime
• Supplier qualification and procurement preferences

The Rubycon 25ZLH330MEFCT78X11.5 offers extended lifetime rating (8000 hours at 105°C versus 5000 hours), which may provide additional margin in thermally demanding applications. Both parts are mechanically and electrically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the 25ZLH330MEFCT78X11.5 be used as a direct replacement for the UTT1E331MPD1TA?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), operating temperature range (-40°C to 105°C), and mechanical dimensions (lead spacing, case diameter, and height). Both are through-hole radial can packages with polar polarization and RoHS3 compliance.

Q: What is the difference in lifetime ratings between these parts?

A: The UTT1E331MPD1TA is rated for 5000 hours at 105°C, while the 25ZLH330MEFCT78X11.5 is rated for 8000 hours at 105°C. This difference reflects manufacturer design and does not affect electrical compatibility or mechanical fit.

Q: Are there packaging differences between these parts?

A: The UTT1E331MPD1TA is supplied in standard packaging, while the 25ZLH330MEFCT78X11.5 is supplied in Cut Tape (CT) format. Both are through-hole components with identical lead spacing and mechanical dimensions suitable for the same PCB footprint.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the UTT1E331MPD1TA and 25ZLH330MEFCT78X11.5 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.22.0020.

Q: What ripple current specifications should be considered?

A: The UTT1E331MPD1TA is rated for 178.8 mA at 120 Hz and 298 mA at 100 kHz. The 25ZLH330MEFCT78X11.5 is rated for 519.75 mA at 120 Hz and 945 mA at 100 kHz. Selection should be based on the actual ripple current requirements of the application circuit.
