Substitute Part Grouping Explanation

Substitution of the MVK50VC4R7ME55TP is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

Capacitance: 4.7 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can - SMD (exact match required)
Case Dimensions: 0.197" Dia (5.00 mm) and Height ≤ 0.222" (5.65 mm)
Surface Mount Land Size: 0.209" L × 0.209" W (5.30 mm × 5.30 mm)
Mounting Type: Surface Mount (exact match required)

Performance Parameters Allowing Variation:

Lifetime @ 105°C: 1000 hours minimum (upgrades to 2000 or 3000 hours acceptable)
Operating Temperature Range: -40°C to 105°C minimum (extended ranges acceptable)
ESR: Values within component design specifications
Ripple Current: Values meeting or exceeding original specification
RoHS Compliance: Upgrades from non-compliant to compliant acceptable

Substitute parts are grouped into three categories: Direct Manufacturer Equivalents (same electrical performance, active status), Parametric Equivalents (enhanced performance characteristics), and Upgrade Parts (extended lifetime or enhanced ratings).

Engineering Selection Recommendations

Direct Replacement (Same Performance Profile):

For applications requiring direct functional equivalence with active product status, select from Chemi-Con's active MVY or MVE series: EMVY500ARA4R7ME55G or EMVE500ARA4R7ME55G. Both maintain the 4.7 µF / 50 V / ±20% specification with 1000-hour lifetime at 105°C and achieve ROHS3 compliance. EMVE500ARA4R7ME55G matches the original -40°C to 105°C operating range exactly.

Active Alternatives from Other Manufacturers:

Cornell Dubilier AVEZ475M50C12T-F and AVES475M50C12T-F provide equivalent electrical performance with active product status and ROHS3 compliance. Both support extended temperature range (-55°C to 105°C). Height increases to 5.50 mm require PCB layout verification.

Nichicon UUQ1H4R7MCL1GB and UWT1H4R7MCL1GB offer equivalent specifications with active status and ROHS3 compliance. UWT1H4R7MCL1GB extends operating range to -55°C to 105°C.

Enhanced Lifetime Options:

KEMET EDH475M050A9DAA and EDH475M050S9DAA provide doubled lifetime (2000 hours at 105°C) while maintaining all electrical equivalence. EDH475M050S9DAA includes AEC-Q200 automotive qualification. Height increases to 5.65 mm.

KEMET EXV475M050A9DAA offers maximum lifetime extension (3000 hours at 105°C) with extended temperature range (-55°C to 105°C) and significantly enhanced ripple current capability (66.5 mA @ 120 Hz versus 19 mA original). Height reaches 5.65 mm maximum.

Avoid for New Designs:

Panasonic EEE-HA1H4R7R carries "Not For New Designs" status despite active inventory and ROHS compliance. Use only for legacy system maintenance where original performance profile is mandatory.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height if the PCB footprint allows?

A: Yes. The original MVK50VC4R7ME55TP has maximum height of 5.20 mm. Substitute parts with heights up to 5.65 mm (KEMET EDH and EXV series) are mechanically compatible if PCB clearance exists. Surface mount land size remains constant at 5.30 mm × 5.30 mm across all listed substitutes.

Q: What is the difference between EMVY500ARA4R7ME55G and EMVE500ARA4R7ME55G?

A: Both are Chemi-Con active equivalents with identical electrical specifications (4.7 µF, 50 V, ±20%, 1000 Hrs @ 105°C). EMVY series operates -55°C to 105°C; EMVE series operates -40°C to 105°C. Select EMVE for applications matching the original temperature range; select EMVY for extended low-temperature operation.

Q: Why do some substitutes have higher ESR or lower ripple current ratings?

A: ESR and ripple current vary by manufacturer design and series. The original MVK50VC4R7ME55TP specifies 42.319 Ohm ESR @ 120 Hz and 19 mA ripple current. Substitutes meeting or exceeding these values are acceptable. KEMET EXV475M050A9DAA, for example, specifies 4 Ohm ESR @ 100 kHz and 66.5 mA ripple current @ 120 Hz, representing superior performance.

Q: Is RoHS compliance mandatory for my application?

A: The original MVK50VC4R7ME55TP is RoHS non-compliant. All listed active substitutes achieve ROHS3 compliance. If your application or supply chain requires RoHS compliance, any active substitute listed meets this requirement. Legacy systems may accept non-compliant parts; verify with your procurement and regulatory requirements.

Q: Can I substitute the MVK50VC4R7ME55TP with a part rated for higher voltage (e.g., 63 V)?

A: No. Voltage rating is a mandatory equivalence criterion. The original part is rated 50 V. Substitutes must be 50 V rated. Higher voltage ratings alter electrical characteristics and circuit behavior. Use only 50 V rated parts.

Q: What does "Parametric Equivalent" mean in the context of EMVE500ARA4R7ME55G?

A: EMVE500ARA4R7ME55G is classified as a parametric equivalent because it maintains all critical electrical specifications (capacitance, voltage, tolerance, lifetime, package) while offering enhanced performance characteristics such as improved ripple current handling and extended temperature range capability compared to the original MVK50VC4R7ME55TP.

Q: Should I select the KEMET EXV475M050A9DAA for all applications?

A: EXV475M050A9DAA offers superior performance (3000-hour lifetime, 66.5 mA ripple current) but increases component height to 5.65 mm. Select this part only when enhanced performance is required and PCB clearance permits. For direct replacement in space-constrained designs, use EMVE500ARA4R7ME55G or equivalent active parts with 5.20 mm height.

Q: What is the inventory status of these substitute parts?

A: All listed substitute parts show active inventory ranging from 754 to 12,345 pieces. UWT1H4R7MCL1GB (Nichicon) shows highest availability at 12,345 pieces. Verify current inventory with your component supplier before design finalization.
