Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parametric matching across electrical and mechanical dimensions. The primary substitution criteria are:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: minimum 16 V (equal or higher acceptable)
• Tolerance: ±20% (matching specification)
• Package type: Radial, Can (mechanical compatibility)
• Lead spacing: 0.138" (4.60 mm) (PCB footprint compatibility)
• Mounting type: Through Hole (assembly process compatibility)
• Operating temperature range: -40°C to 105°C (environmental compatibility)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

Substitute parts are classified into two categories: Parametric Equivalents (identical electrical and mechanical specifications with different series designation or product status) and Similar parts (matching core parameters with allowable variations in voltage rating, lifetime, or ripple current capacity).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (UTS1C331MPD1TA and UTS1C331MPD1TD): These Nichicon UTS series parts provide direct functional replacement for the obsolete UTT1C331MPD1TD. Both maintain identical electrical specifications (330 µF, 16 V, ±20% tolerance, 5000 Hrs @ 105°C) and mechanical dimensions (0.315" diameter, 0.413" height, 0.138" lead spacing). The primary distinction between these two parametric equivalents is product availability. Both are classified as Active products and maintain full ROHS3 compliance. Selection between UTS1C331MPD1TA and UTS1C331MPD1TD should be based on inventory availability and supply chain considerations.

Similar Part (25ZLJ330M8X11.5): The Rubycon ZLJ series part offers functional substitution with the following considerations: voltage rating is elevated to 25 V (providing additional safety margin in applications operating below 16 V), lifetime is extended to 9000 hours at 105°C (exceeding the original 5000-hour specification), and physical height increases to 0.512" (13.00 mm) compared to the original 0.413" (10.50 mm). This height difference requires verification of available PCB clearance. The part maintains identical capacitance, tolerance, lead spacing, and diameter. ROHS3 compliance is maintained. This part is suitable for applications where increased voltage headroom and extended operational lifetime provide design benefits and where the increased height does not create mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can UTS1C331MPD1TA and UTS1C331MPD1TD be used interchangeably with UTT1C331MPD1TD?

A: Yes. Both UTS series parts are parametric equivalents with identical electrical ratings (330 µF, 16 V, ±20% tolerance, 5000 Hrs @ 105°C) and mechanical dimensions (lead spacing, diameter, height). They are direct functional replacements suitable for PCB retrofit without design modification.

Q: What is the primary difference between the two Nichicon UTS parametric equivalents?

A: UTS1C331MPD1TA and UTS1C331MPD1TD are electrically and mechanically identical. The designation difference reflects manufacturing or packaging variations. Selection should be based on current inventory availability and supply chain lead times.

Q: Can the Rubycon 25ZLJ330M8X11.5 be used as a direct replacement?

A: The Rubycon part is functionally compatible with one mechanical consideration: the seated height is 0.512" (13.00 mm) versus the original 0.413" (10.50 mm). Verify that available PCB clearance accommodates this 0.099" (2.50 mm) height increase. Electrical compatibility is confirmed across all rated parameters.

Q: Why is the voltage rating higher on the Rubycon substitute?

A: The 25 V rating on the Rubycon part provides additional voltage margin compared to the original 16 V specification. This is not a limitation but rather an enhancement that allows operation in circuits with higher transient voltage conditions while maintaining the same physical footprint and capacitance value.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (UTS1C331MPD1TA, UTS1C331MPD1TD, and 25ZLJ330M8X11.5) maintain ROHS3 compliance, meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: What is the impact of the extended lifetime specification on the Rubycon part?

A: The Rubycon 25ZLJ330M8X11.5 specifies 9000 hours at 105°C compared to 5000 hours for the original part. This extended lifetime indicates improved thermal stability and longer operational endurance, providing design margin for applications requiring extended service life.
