Part Overview

The MVE6.3VC33RME55TP is a 33 µF, 6.3 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Chemi-Con. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. The part operates across a temperature range of -40°C to 105°C with a 1000-hour lifetime rating at 105°C, suitable for general-purpose applications requiring stable capacitance performance in compact form factors.

Substitute Part Grouping Explanation

Substitute parts are organized into three categories based on electrical and mechanical compatibility:

Direct Equivalents (Same Voltage Rating - 6.3 V): Parts maintaining identical capacitance (33 µF), voltage rating (6.3 V), tolerance (±20%), package type (Radial, Can - SMD), and physical dimensions (5.00mm diameter, 5.20-5.40mm height). These parts are interchangeable without circuit redesign.

Parametric Equivalents (Same Voltage Rating - 6.3 V, Active Status): Active production parts from Chemi-Con's Alchip™ series with matching electrical specifications and improved RoHS3 compliance. Physical dimensions remain within compatible range.

Upgrade Options (Higher Voltage Rating - 10 V): Parts with elevated voltage rating (10 V) while maintaining 33 µF capacitance and ±20% tolerance. These provide enhanced voltage margin and are mechanically compatible. Voltage derating must be evaluated for circuit application.

Substitution eligibility is determined by: capacitance value, tolerance, voltage rating compatibility, package type, physical dimensions, and surface mount land pattern. All listed substitutes maintain the same polarization (polar) and MSL rating (1).

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Specifications):

EMVE6R3ARA330ME55G from Chemi-Con is the primary parametric equivalent, offering identical capacitance, voltage, tolerance, and physical dimensions with active product status and ROHS3 compliance. This part matches the original operating temperature range (-40°C to 105°C) and ripple current specification (34 mA @ 120 Hz).

EMVY6R3ARA330ME55G provides an alternative from Chemi-Con's Alchip™ series with extended temperature range (-55°C to 105°C) and higher ripple current capability (38 mA @ 120 Hz), both with ROHS3 compliance and active status.

For Cross-Manufacturer Substitution (Same Voltage Rating):

AVES336M06C12T-F and AVEZ336M06C12T-F from Cornell Dubilier Electronics maintain 33 µF, 6.3 V specifications with ROHS3 compliance and active production status. AVEZ336M06C12T-F offers significantly higher ripple current (88 mA @ 120 Hz) and lower impedance (1.5 Ohms). Physical height is 0.217" (5.50mm), which is compatible with the 5.30mm x 5.30mm land pattern.

UUQ0J330MCL1GB and UWT0J330MCL1GB from Nichicon provide 33 µF, 6.3 V specifications with ROHS3 compliance and active status. UWT0J330MCL1GB extends the operating temperature to -55°C. Both maintain compatible physical dimensions and land patterns.

For Voltage Upgrade Applications:

EMVE100ARA330ME55G and EMVY100ARA330ME55G from Chemi-Con offer 10 V rating with 33 µF capacitance, providing enhanced voltage margin while maintaining identical physical dimensions and land patterns. Both are ROHS3 compliant and active. EMVY100ARA330ME55G extends temperature range to -55°C.

AVES336M10C12T-F from Cornell Dubilier Electronics provides 10 V, 33 µF with ROHS3 compliance and active status, with measured ESR of 13.1 Ohm @ 120 Hz.

All recommended substitutes maintain polar polarization, MSL rating 1, and surface mount compatibility with the original part's land pattern.

Frequently Asked Questions (FAQ)

Q: Can I use a 10 V rated capacitor in place of the 6.3 V original part?

A: Yes, from an electrical standpoint. Higher voltage-rated capacitors are mechanically and electrically compatible with lower voltage applications. The 10 V options (EMVE100ARA330ME55G, EMVY100ARA330ME55G, AVES336M10C12T-F) maintain identical capacitance (33 µF), tolerance (±20%), physical dimensions, and land patterns. Verify that circuit design does not impose size or cost constraints that would be affected by the upgrade.

Q: What is the difference between direct equivalents and parametric equivalents?

A: Direct equivalents maintain all electrical parameters of the original part, including ESR and ripple current specifications. Parametric equivalents match capacitance, voltage, tolerance, and physical dimensions but may have different ESR or ripple current values. Both categories are mechanically interchangeable.

Q: Are there temperature range differences I should consider?

A: Yes. The original MVE6.3VC33RME55TP operates from -40°C to 105°C. Several substitutes extend the lower limit to -55°C (EMVY6R3ARA330ME55G, AVES336M06C12T-F, AVEZ336M06C12T-F, UWT0J330MCL1GB, EMVY100ARA330ME55G, 10SKV33M5X5.5, AVES336M10C12T-F). For applications requiring operation below -40°C, select parts with -55°C minimum rating.

Q: What does RoHS3 compliance mean for my design?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations. The original part is RoHS non-compliant. All recommended substitutes are ROHS3 compliant, which is required for many markets and applications. If your design requires non-compliant parts, this must be explicitly specified.

Q: Do all substitutes fit the same PCB footprint?

A: All substitutes maintain the same 5.30mm x 5.30mm surface mount land pattern. Physical heights vary slightly: original and most Chemi-Con parts are 5.20mm, while Cornell Dubilier and some Nichicon parts are 5.40-5.50mm. These height differences are within typical PCB clearance tolerances for surface mount applications.

Q: Which substitute offers the best ripple current performance?

A: AVEZ336M06C12T-F from Cornell Dubilier Electronics provides the highest ripple current at 88 mA @ 120 Hz with 1.5 Ohm impedance, compared to the original 34 mA @ 120 Hz specification. This part is suitable for applications requiring enhanced current handling capability.

Q: Can I mix different substitute parts in the same design?

A: Yes, provided all selected parts meet the circuit's electrical requirements (capacitance, voltage, tolerance, ESR, ripple current). Mixing manufacturers is acceptable from a functional standpoint, though procurement and quality control may prefer standardization on a single part number per design revision.
