MVY50VC2R2MD55TP Equivalent & Substitute Parts

Part Overview

The MVY50VC2R2MD55TP is a 2.2 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Chemi-Con. This component is classified as obsolete, indicating discontinued production and limited availability from original sources. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 1000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and low impedance characteristics.

Identification of equivalent and substitute parts is necessary due to the obsolete status of the MVY50VC2R2MD55TP. Active production alternatives from multiple manufacturers provide equivalent electrical performance while offering improved availability, RoHS3 compliance, and extended supply chain support.

Engineering Selection Recommendations

Primary Recommendation: EMVY500ARA2R2MD55G

The EMVY500ARA2R2MD55G is the direct parametric equivalent manufactured by Chemi-Con, the original manufacturer of the MVY50VC2R2MD55TP. This part maintains identical electrical specifications while offering active production status and ROHS3 compliance. Selection of this part eliminates potential compatibility concerns related to manufacturer-specific design variations and provides continuity with the original design intent.

Secondary Recommendations (Multi-Source Strategy):

AVEZ225M50B12T-F (Cornell Dubilier Electronics) provides equivalent impedance (5 Ohms) and ripple current performance (30 mA @ 100 kHz) matching the original specification. ROHS3 compliance and active production status support long-term supply chain stability. Height specification of 5.50mm accommodates standard PCB design tolerances.

UWT1H2R2MCL1GB (Nichicon) offers the highest inventory availability (2517 pcs) and ROHS3 compliance. While ESR data is not provided, the part meets all critical electrical and mechanical parameters. Height specification of 5.40mm provides compatibility with standard PCB layouts.

Alternative Options (Acceptable Performance):

225SMH050MHR and AVES225M50B12T-F are acceptable substitutes with ROHS3 compliance and active production status. These parts exhibit higher ESR values (90.43 Ohm and 90.4 Ohm @ 120 Hz respectively) compared to the 5 Ohm baseline. This characteristic results in reduced ripple current capacity at low frequencies (16 mA and 10 mA @ 120 Hz respectively) but maintains adequate performance at high frequencies (24 mA and 15 mA @ 10 kHz respectively). Selection of these parts is appropriate for applications where low-frequency ripple current demands do not exceed specified ratings.

Compliance Considerations:

All recommended substitute parts hold ROHS3 compliance certification, addressing regulatory requirements not met by the obsolete MVY50VC2R2MD55TP. All parts maintain REACH Unaffected status and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the MVY50VC2R2MD55TP be directly replaced with EMVY500ARA2R2MD55G without PCB modification?

A: Yes. The EMVY500ARA2R2MD55G maintains identical capacitance (2.2 µF), voltage rating (50 V), tolerance (±20%), temperature range (-55°C to 105°C), lifetime (1000 Hrs @ 105°C), impedance (5 Ohms), physical diameter (4.00mm), and surface mount land size (4.30mm x 4.30mm). The height difference of 0.00mm (5.20mm vs 5.20mm) presents no clearance concerns. Direct substitution is supported.

Q: What is the significance of impedance differences between substitute parts?

A: Impedance directly affects ripple current capacity. The original MVY50VC2R2MD55TP and recommended substitutes EMVY500ARA2R2MD55G and AVEZ225M50B12T-F specify 5 Ohms impedance. Parts such as 225SMH050MHR and AVES225M50B12T-F specify 90.43 Ohm and 90.4 Ohm @ 120 Hz respectively. Higher impedance reduces ripple current handling capacity at low frequencies. Selection depends on application ripple current requirements at specific frequencies.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed (EMVY500ARA2R2MD55G, 225SMH050MHR, AVES225M50B12T-F, AVEZ225M50B12T-F, UWT1H2R2MCL1GB) hold ROHS3 compliance certification. The original MVY50VC2R2MD55TP is RoHS non-compliant. Substitution addresses regulatory compliance requirements for new designs and manufacturing processes.

Q: What is the maximum height variation acceptable for PCB layout compatibility?

A: All substitute parts specify heights between 5.20mm and 5.50mm. Standard PCB design tolerances accommodate this 0.30mm variation. Surface mount land size remains constant at 4.30mm x 4.30mm across all parts. No PCB redesign is required for height variations within this range.

Q: Which substitute part offers the best long-term supply availability?

A: UWT1H2R2MCL1GB (Nichicon) currently maintains the highest inventory level at 2517 pcs. AVEZ225M50B12T-F (Cornell Dubilier Electronics) provides 822 pcs, and EMVY500ARA2R2MD55G (Chemi-Con) provides 836 pcs. All three parts hold active production status, supporting sustained availability. Selection should consider both current inventory and manufacturer production roadmap.

Q: Can substitute parts with different ESR values be used interchangeably in all applications?

A: No. ESR affects ripple current performance and thermal characteristics. Parts with 5 Ohms impedance (EMVY500ARA2R2MD55G, AVEZ225M50B12T-F) support higher ripple current capacity compared to parts with 90+ Ohm impedance (225SMH050MHR, AVES225M50B12T-F). Application-specific ripple current requirements at operating frequencies must be verified against substitute part specifications before selection.

Q: Is moisture sensitivity level identical across all substitute parts?

A: Yes. All parts, including the original MVY50VC2R2MD55TP and all substitute options, specify Moisture Sensitivity Level 1 (Unlimited). This classification indicates no moisture sensitivity restrictions for storage, handling, or reflow processes.

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

A: Parametric equivalents (EMVY500ARA2R2MD55G) match all electrical and mechanical specifications of the original part. Direct substitutes (225SMH050MHR, AVES225M50B12T-F, AVEZ225M50B12T-F, UWT1H2R2MCL1GB) meet critical specifications but may exhibit variations in secondary parameters such as ESR or ripple current at specific frequencies. Both categories support functional replacement; selection depends on application sensitivity to secondary parameter variations.
