MZA35VC33RMF61TP Equivalent & Substitute Parts

Part Overview

The MZA35VC33RMF61TP is a 33 µF, 35 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Chemi-Con. This component is classified as obsolete, with 649 units available in current inventory. The MZA series operates across -55°C to 105°C with a 2000-hour lifetime rating at 105°C, designed for general-purpose applications requiring stable capacitance and low impedance characteristics.

Due to the obsolete status of the MZA35VC33RMF61TP, equivalent and substitute parts from active manufacturers are necessary to ensure design continuity and long-term supply chain reliability for new production runs and field replacements.

Engineering Selection Recommendations

For Automotive Applications: Select from EMZA350ARA330MF61G (Chemi-Con), 35JZV33M6.3X6.1 (Rubycon), 35TZV33M6.3X6.1 (Rubycon), AFK336M35D16T-F (Cornell Dubilier Electronics), EEE-FK1V330P (Panasonic), EEE-FK1V330AP (Panasonic), EEV336M035S9GAA (KEMET), EXV336M035S9GAA (KEMET), or UUD1V330MCL1GS (Nichicon). All carry AEC-Q200 certification and ROHS3 compliance.

For General-Purpose Applications: UCL1V330MCL1GS (Nichicon) provides parametric equivalence with superior ripple current handling (300 mA @ 100 kHz) and lower impedance (260 mOhms), suitable for non-automotive designs without automotive-grade certification requirements.

For Extended Lifetime Requirements: EXV336M035S9GAA (KEMET) offers 3000-hour lifetime rating at 105°C, exceeding the 2000-hour baseline of the original part.

For Impedance-Critical Applications: UCL1V330MCL1GS (Nichicon) provides the lowest impedance at 260 mOhms. EEV336M035S9GAA and EXV336M035S9GAA (KEMET) operate at 520 mOhms, acceptable for applications tolerating higher impedance.

For Height-Constrained PCB Layouts: EEV336M035S9GAA and EXV336M035S9GAA (KEMET) offer reduced seated height of 0.222" (5.65mm), compared to the original 0.228" (5.80mm).

All recommended substitutes maintain identical capacitance, voltage rating, tolerance, operating temperature range, and package type. Verify PCB land pattern compatibility, particularly for AFK336M35D16T-F, which specifies 0.260" L x 0.307" W surface mount land size.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MZA35VC33RMF61TP with any of the listed substitutes?

A: Direct replacement requires matching capacitance (33 µF), voltage rating (35 V), tolerance (±20%), package type (Radial, Can - SMD), and physical dimensions. All listed substitutes meet these criteria. Verify PCB land pattern compatibility before assembly, particularly for AFK336M35D16T-F.

Q: What is the difference between automotive-rated and general-purpose substitutes?

A: Automotive-rated substitutes carry AEC-Q200 certification and are qualified for automotive temperature cycling and reliability standards. General-purpose substitutes lack this certification. Select automotive-rated parts for automotive applications; general-purpose parts are acceptable for consumer and industrial applications without automotive requirements.

Q: Does impedance variation affect circuit performance?

A: Impedance ranges from 260 mOhms (UCL1V330MCL1GS) to 520 mOhms (KEMET EEV and EXV series). Lower impedance provides better high-frequency performance and reduced voltage ripple. Select based on circuit requirements; most general-purpose applications tolerate the 360 mOhms baseline.

Q: Are there height restrictions for PCB assembly?

A: The original part specifies 0.228" (5.80mm) seated height. Most active substitutes increase to 0.240" (6.10mm). KEMET EEV336M035S9GAA and EXV336M035S9GAA reduce to 0.222" (5.65mm). Verify PCB clearance before selection.

Q: What is the significance of RoHS3 compliance?

A: RoHS3 compliance indicates the part meets current European Union Restriction of Hazardous Substances regulations. The original MZA35VC33RMF61TP is RoHS non-compliant. All active substitutes are ROHS3 compliant, required for new designs and many regulatory jurisdictions.

Q: Can I use UCL1V330MCL1GS in automotive applications?

A: UCL1V330MCL1GS lacks AEC-Q200 certification and is rated for general-purpose applications. It is not qualified for automotive use. Select AEC-Q200 certified parts for automotive designs.

Q: What is the difference between EEE-FK1V330P and EEE-FK1V330AP?

A: Both are Panasonic FK series, 33 µF, 35 V, ±20% tolerance with identical electrical specifications. EEE-FK1V330AP supports high-temperature reflow processing. Select based on manufacturing process requirements.

Q: Does lifetime rating affect part selection?

A: The original part and most substitutes specify 2000 hours @ 105°C. EXV336M035S9GAA (KEMET) provides 3000 hours @ 105°C for applications requiring extended operational life. Select based on system reliability requirements.
