Equivalent & Substitute Parts for MVA50VC4R7MD55TP

Part Overview

The MVA50VC4R7MD55TP is a 4.7 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Chemi-Con. This component is classified as obsolete, indicating that direct procurement from the original manufacturer may be limited or unavailable. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, making it suitable for general-purpose applications requiring stable capacitance performance in standard operating conditions.

Due to its obsolete status, identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for design continuity, production support, and long-term component availability.

Substitute Part Grouping Explanation

Substitution of the MVA50VC4R7MD55TP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 4.7 µF (exact match required)
• Voltage rating: 50 V (minimum requirement; higher ratings acceptable)
• Tolerance: ±20% (matching tolerance band)
• Operating temperature range: -40°C to 85°C (minimum requirement)
• Lifetime specification: 2000 Hrs @ 85°C (minimum requirement)
• Polarization: Polar (must match)

Mechanical Equivalence Criteria:

• Package type: Radial, Can - SMD (exact match required)
• Mounting type: Surface Mount (exact match required)
• Diameter: 0.157" (4.00mm) (exact match required)
• Surface mount land size: 0.169" L x 0.169" W (4.30mm x 4.30mm) (exact match required)
• Height seated (max): Must not exceed 0.205" (5.20mm) for PCB layout compatibility

Functional Equivalence Criteria:

• Ripple current capability at low frequency: minimum 18 mA @ 120 Hz
• Moisture sensitivity level: MSL 1 (Unlimited) or equivalent

Substitute parts must satisfy all electrical and mechanical criteria simultaneously. Parts with higher height dimensions, different land sizes, or incompatible package configurations are not suitable replacements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: EMVA500ARA4R7MD55G

The EMVA500ARA4R7MD55G is the optimal substitute for the MVA50VC4R7MD55TP. This part is manufactured by Chemi-Con (same original manufacturer) and maintains exact mechanical compatibility with identical height and land size specifications. The EMVA500ARA4R7MD55G is classified as active product status, ensuring long-term availability and supply chain continuity. The part achieves ROHS3 compliance, addressing regulatory requirements that the original obsolete part does not meet. All electrical parameters match the main part exactly, including capacitance, voltage rating, tolerance, operating temperature range, and lifetime specification.

Secondary Substitute: EDK475M050A9BAA

The EDK475M050A9BAA, manufactured by KEMET, provides a direct electrical equivalent with active product status and ROHS3 compliance. This part meets all electrical specifications and maintains the required surface mount land size. However, the seated height is 0.222" (5.65mm), which exceeds the original specification of 0.205" (5.20mm). This height difference may impact PCB layout compatibility in space-constrained applications. The EDK475M050A9BAA is suitable for applications where vertical clearance permits the additional 0.017" (0.45mm) height.

Secondary Substitute: EDK475M050S9BAA

The EDK475M050S9BAA, also manufactured by KEMET, is electrically equivalent to EDK475M050A9BAA with identical height specifications. This variant includes AEC-Q200 automotive qualification and is designated for automotive applications. The same height consideration applies: the 0.222" (5.65mm) seated height exceeds the original specification. Selection of this part is appropriate only for automotive-grade applications requiring AEC-Q200 certification.

Alternative Substitute: UWR1H4R7MCL1GB

The UWR1H4R7MCL1GB, manufactured by Nichicon, maintains exact mechanical compatibility with height and land size specifications matching the original part. However, this part is classified as obsolete, similar to the main part, which limits its long-term availability advantage. The ripple current capability at low frequency is significantly higher (71 mA @ 120 Hz versus 18 mA @ 120 Hz), which may introduce unnecessary performance margin in general-purpose applications. ROHS3 compliance is achieved. This part is suitable only when EMVA500ARA4R7MD55G and KEMET alternatives are unavailable.

Compliance Consideration:

The original MVA50VC4R7MD55TP is RoHS non-compliant. All active substitute parts (EMVA500ARA4R7MD55G, EDK475M050A9BAA, EDK475M050S9BAA) achieve ROHS3 compliance, supporting regulatory requirements for new designs and production environments with RoHS mandates.

Frequently Asked Questions (FAQ)

Q: Can the EDK475M050A9BAA or EDK475M050S9BAA be used as direct replacements despite their greater height?

A: These parts are electrically equivalent and mechanically compatible at the land size level. However, the seated height of 0.222" (5.65mm) exceeds the original specification of 0.205" (5.20mm). Substitution is permissible only if PCB layout and component clearance analysis confirms that the additional 0.017" (0.45mm) height does not violate design constraints, such as proximity to other components, enclosure clearance, or connector positioning.

Q: What is the primary advantage of EMVA500ARA4R7MD55G over other substitutes?

A: The EMVA500ARA4R7MD55G is manufactured by the same original manufacturer (Chemi-Con) and maintains exact dimensional compatibility, including the critical seated height specification of 0.205" (5.20mm). This part is active product status, ensuring supply availability. It achieves ROHS3 compliance and requires no PCB layout modifications.

Q: Why is UWR1H4R7MCL1GB listed as an alternative if it is also obsolete?

A: The UWR1H4R7MCL1GB is included as a documented substitute option for applications where active parts are temporarily unavailable or for legacy system support. However, its obsolete status limits long-term procurement viability. Priority should be given to active alternatives such as EMVA500ARA4R7MD55G.

Q: Are there differences in ripple current handling between the substitute parts?

A: Yes. The UWR1H4R7MCL1GB exhibits significantly higher ripple current capability at low frequency (71 mA @ 120 Hz) compared to the original part and other substitutes (18 mA @ 120 Hz). The KEMET parts (EDK475M050A9BAA and EDK475M050S9BAA) maintain the same ripple current specification as the original. For general-purpose applications, the ripple current difference is not a limiting factor in substitution decisions.

Q: What packaging format should be selected for production environments?

A: The EMVA500ARA4R7MD55G is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The UWR1H4R7MCL1GB is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on production volume and assembly equipment compatibility. For high-volume manufacturing, Tape & Reel format is standard.

Q: Is RoHS compliance a mandatory consideration for substitution?

A: RoHS compliance is mandatory for applications subject to regulatory requirements in regions enforcing RoHS directives. All active substitute parts achieve ROHS3 compliance, whereas the original MVA50VC4R7MD55TP is RoHS non-compliant. For new designs or production environments with RoHS mandates, substitution to a compliant part is required.

Q: Can the EDK475M050S9BAA be used in non-automotive applications?

A: Yes. The EDK475M050S9BAA is electrically and mechanically equivalent to EDK475M050A9BAA. The AEC-Q200 automotive qualification is an additional certification that does not restrict use in general-purpose applications. However, the height specification remains 0.222" (5.65mm), requiring PCB layout verification.

Q: What is the impact of tolerance on substitution?

A: All substitute parts maintain the ±20% tolerance specification, matching the original part. Tolerance equivalence ensures that capacitance variation across the specified range remains consistent, supporting circuit performance requirements without design modification.
