Nichicon UVZ1C330MDD Equivalent & Substitute Parts

Part Overview

The Nichicon UVZ1C330MDD is a 33 µF, 16 V aluminum electrolytic capacitor in radial configuration with a 1000-hour lifetime rating at 105°C. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The radial, can-style package with 0.079" (2.00 mm) lead spacing and 0.197" (5.00 mm) diameter form factor defines the mechanical compatibility envelope for direct substitution.

Substitute Part Grouping Explanation

Substitution of the UVZ1C330MDD is determined by the following criteria:

Mechanical Compatibility: Lead spacing (0.079"), package diameter (0.197"), and height must remain within the specified envelope to ensure PCB footprint compatibility.

Electrical Equivalence: Capacitance value (33 µF) and tolerance (±20%) must be maintained. Voltage rating may be equal or higher without functional impact, as the circuit operates at 16 V maximum.

Thermal Performance: Lifetime rating at 105°C may be equal or higher. Extended lifetime (2000 Hrs) provides improved reliability margin.

Polarization and Mounting: Polar radial configuration with through-hole mounting must be preserved.

Substitute parts are grouped into two categories:

Upgrade Substitutes: Higher voltage ratings (25 V, 35 V, 50 V) or extended lifetime (2000 Hrs) with identical mechanical form factor. These provide enhanced performance margins while maintaining full backward compatibility.

Similar Substitutes: Same voltage rating (16 V) with extended lifetime or different manufacturer, maintaining direct functional equivalence.

Engineering Selection Recommendations

Direct Mechanical Replacement (Same Height): UPM1E330MDD, UPS1V330MDD, UVY1H330MDD, UVZ1H330MDD, UVZ1V330MDD, UKA1H330MDD, 25PX33MEFC5X11, and 336KXM035M all maintain the maximum height of 0.492" (12.50 mm), ensuring compatibility with existing PCB layouts without modification.

Reduced Height Option: UPW1C330MDD offers a lower profile at 0.433" (11.00 mm) height, suitable for space-constrained applications where the reduced height does not conflict with component placement.

Active Product Status: 25PX33MEFC5X11 (Rubycon) and 336KXM035M (Cornell Dubilier / Illinois Capacitor) are currently in active production, providing long-term supply continuity and availability advantages over obsolete Nichicon alternatives.

Compliance: All listed substitutes maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original part.

Voltage Margin Selection: For applications requiring enhanced reliability, UPM1E330MDD, UPS1V330MDD, UVY1H330MDD, UVZ1H330MDD, UVZ1V330MDD, or UKA1H330MDD provide voltage ratings of 25 V or higher, offering operational margin above the 16 V circuit requirement.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V or 35 V rated capacitor in place of the 16 V UVZ1C330MDD?

A: Yes. A higher voltage rating does not affect circuit operation. The capacitor will function identically at 16 V or below. Higher voltage ratings provide increased safety margin and are electrically compatible.

Q: What is the difference between the Nichicon UVZ and UPW series at 16 V?

A: Both UVZ1C330MDD and UPW1C330MDD are 33 µF, 16 V radial capacitors. The primary difference is lifetime rating: UVZ1C330MDD is rated for 1000 hours at 105°C, while UPW1C330MDD is rated for 2000 hours. UPW1C330MDD also has a slightly reduced height (0.433" vs. 0.492").

Q: Are Rubycon and Cornell Dubilier capacitors compatible with Nichicon footprints?

A: Yes, provided mechanical dimensions match. The 25PX33MEFC5X11 (Rubycon) and 336KXM035M (Cornell Dubilier) both maintain the 0.079" lead spacing, 0.197" diameter, and 0.492" maximum height, ensuring PCB footprint compatibility.

Q: Why would I choose an active product over an obsolete Nichicon part?

A: Active products such as 25PX33MEFC5X11 and 336KXM035M offer guaranteed long-term availability, consistent manufacturing, and supply chain reliability. Obsolete parts face increasing scarcity and potential price volatility.

Q: Does capacitance tolerance affect substitution?

A: All listed substitutes maintain ±20% tolerance, matching the original specification. Tolerance is not a differentiating factor for substitution eligibility.

Q: What is the significance of ripple current ratings?

A: Ripple current capacity indicates the maximum AC current the capacitor can handle at specified frequencies. Higher ripple current ratings provide margin for applications with significant AC ripple content. Substitutes with equal or higher ripple current ratings are fully compatible.

Q: Can I substitute UVZ1C330MDD with UKA1H330MDD?

A: Yes. UKA1H330MDD is a 33 µF, 50 V capacitor with 2000-hour lifetime, identical mechanical form factor, and higher voltage and lifetime ratings. It is a direct upgrade substitute with enhanced performance margins.
