Substitute Part Grouping Explanation
Substitute parts for MVY16VC33RMF55TP are classified into three categories based on electrical and mechanical compatibility:
Parametric Equivalent (Same Voltage Rating - 16V): Parts maintaining identical capacitance (33 µF), voltage rating (16 V), tolerance (±20%), physical dimensions (0.248" diameter, 0.205" height), and surface mount land size (0.260" x 0.260"). These parts are direct functional replacements with no circuit redesign required. The parametric equivalent EMVY160ARA330MF55G from Chemi-Con's active Alchip™-MVY series provides identical electrical performance with RoHS3 compliance.
Upgrade Substitutes (Higher Voltage Ratings - 25V, 35V): Parts with identical capacitance (33 µF), tolerance (±20%), and physical dimensions but rated for higher voltages (25 V or 35 V). These substitutes are electrically compatible in circuits designed for 16 V operation, as higher-rated components operate safely at lower applied voltages. Upgrade substitutes include EMVY250ARA330MF55G (25 V) and EMVY350ARA330MF55G (35 V) from Chemi-Con, plus AVES336M25D16T-F, AVEZ336M25D16T-F, and AVEZ336M35D16T-F from Cornell Dubilier Electronics.
Direct Manufacturer Alternatives (Same Specifications, Different Manufacturers): Parts from alternative manufacturers (Cornell Dubilier Electronics, Rubycon) with matching or superior electrical characteristics. AVES336M16D16T-F and AVEZ336M16D16T-F maintain 16 V rating with identical physical form factor. These alternatives provide supply diversification while maintaining circuit compatibility.
Substitution is determined by the following key parameters: capacitance value (33 µF fixed), tolerance (±20% fixed), physical dimensions (0.248" diameter, 0.205"-0.217" height, 0.260" x 0.260" land size fixed), surface mount package type (Radial, Can - SMD fixed), operating temperature range (-55°C to 105°C fixed), and lifetime rating (1000 Hrs @ 105°C fixed).

Engineering Selection Recommendations
Primary Recommendation: EMVY160ARA330MF55G
EMVY160ARA330MF55G from Chemi-Con is the direct parametric equivalent for MVY16VC33RMF55TP. This part maintains identical electrical specifications (33 µF, 16 V, ±20% tolerance, 1 Ohm impedance, 140 mA ripple current at 100 kHz) and physical dimensions (0.248" diameter, 0.205" height, 0.260" x 0.260" land size). The part is in active production status with 1058 units in stock and carries RoHS3 compliance certification, addressing the non-compliance status of the obsolete original part. This substitution requires no circuit modifications and provides identical performance characteristics.
Secondary Recommendation for Voltage Margin: EMVY250ARA330MF55G or EMVY350ARA330MF55G
When circuit design permits higher voltage ratings, EMVY250ARA330MF55G (25 V) or EMVY350ARA330MF55G (35 V) provide enhanced voltage margin while maintaining identical capacitance, tolerance, and physical form factor. Both parts are active production items with RoHS3 compliance. These upgrades are suitable for applications where voltage transients or design margin improvements are beneficial. EMVY250ARA330MF55G has 6624 units in stock; EMVY350ARA330MF55G has 2798 units in stock.
Alternative Manufacturer Options: Cornell Dubilier Electronics Series
AVEZ336M16D16T-F provides a 16 V equivalent from Cornell Dubilier Electronics with superior ripple current handling (170 mA @ 100 kHz versus 140 mA) and lower impedance (850 mOhms versus 1 Ohm). This part is active production with RoHS3 compliance and 689 units in stock. AVEZ336M25D16T-F and AVEZ336M35D16T-F offer higher voltage ratings with the same performance advantages. These alternatives provide supply chain diversification from a different manufacturer while maintaining compatibility.
Rubycon Options: Last Time Buy Status
25SZV33M6.3X5.5 from Rubycon provides a 25 V upgrade substitute with matching impedance (1 Ohm) and ripple current (140 mA @ 100 kHz). This part is designated Last Time Buy with 2005 units in stock and RoHS3 compliance. Selection of Rubycon parts should account for their limited availability status.
All recommended substitutes maintain the same surface mount radial can package, operating temperature range (-55°C to 105°C), and 1000-hour lifetime rating at 105°C. Selection among alternatives depends on voltage margin requirements, supply chain preferences, and inventory availability.
Frequently Asked Questions (FAQ)
Q: Can EMVY160ARA330MF55G directly replace MVY16VC33RMF55TP without PCB modifications?
A: Yes. EMVY160ARA330MF55G is a parametric equivalent with identical capacitance (33 µF), voltage rating (16 V), tolerance (±20%), physical dimensions (0.248" diameter, 0.205" height), and surface mount land size (0.260" x 0.260"). No PCB layout changes are required.
Q: What is the difference between parametric equivalent and upgrade substitute parts?
A: Parametric equivalent parts (EMVY160ARA330MF55G) maintain the same voltage rating (16 V) as the original part. Upgrade substitutes (EMVY250ARA330MF55G, EMVY350ARA330MF55G) have higher voltage ratings (25 V or 35 V) but identical capacitance and physical dimensions. Upgrade substitutes are electrically compatible in 16 V circuits and provide additional voltage margin.
Q: Are there physical dimension differences between substitute parts?
A: Most substitutes maintain the original 0.248" diameter and 0.260" x 0.260" land size. However, some Cornell Dubilier (AVES, AVEZ series) and Rubycon parts have a maximum seated height of 0.217" (5.50mm) compared to the original 0.205" (5.20mm). Verify PCB clearance before selection if height is constrained.
Q: What does RoHS3 compliance mean for this application?
A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. The original MVY16VC33RMF55TP is RoHS non-compliant. All recommended substitutes carry RoHS3 compliance, making them suitable for applications requiring environmental compliance.
Q: Can I use a 25 V or 35 V rated capacitor in a 16 V circuit?
A: Yes. Higher voltage-rated capacitors operate safely at lower applied voltages. EMVY250ARA330MF55G (25 V) and EMVY350ARA330MF55G (35 V) are electrically compatible in circuits designed for 16 V operation and provide additional voltage margin for transient protection.
Q: What is the significance of impedance differences between parts?
A: Impedance affects high-frequency ripple current handling and noise filtering performance. The original part and most Chemi-Con substitutes have 1 Ohm impedance. Cornell Dubilier AVEZ series parts have 850 mOhms impedance, providing superior high-frequency performance. For general-purpose applications, both impedance values are acceptable.
Q: Why are some substitute parts marked "Last Time Buy"?
A: Last Time Buy designation indicates the manufacturer is discontinuing the product line. Rubycon parts 25SKV33M6.3X5.5 and 25SZV33M6.3X5.5 are in this status. While currently available (2005 and 3886 units respectively), future availability is limited. For long-term supply security, prioritize active production parts (Chemi-Con Alchip™-MVY series or Cornell Dubilier AVES/AVEZ series).
Q: What is the difference between AVES and AVEZ series from Cornell Dubilier?
A: Both series maintain identical capacitance and voltage ratings. AVEZ series provides superior ripple current handling (170 mA @ 100 kHz versus 50 mA for AVES at 10 kHz) and lower impedance (850 mOhms versus 11.1 Ohms ESR for AVES). AVEZ is recommended for applications requiring higher ripple current capacity.
Q: Are all substitute parts available in Tape & Reel packaging?
A: Packaging varies by part number. EMVY250ARA330MF55G, EMVY350ARA330MF55G, 25SKV33M6.3X5.5, 25SZV33M6.3X5.5, and AVEZ336M25D16T-F are specified as Tape & Reel (TR). EMVY160ARA330MF55G, AVES336M16D16T-F, AVES336M25D16T-F, AVEZ336M16D16T-F, and AVEZ336M35D16T-F have packaging not specified or alternative formats. Confirm packaging requirements with supplier before procurement.
