Key Parameters

Substitute Part Grouping Explanation

Substitution of the MALIEYN07BA447J42K is determined by strict equivalence across the following critical parameters:

Capacitance value must remain 4700 µF. Tolerance must be ±20%. Rated voltage must be equal to or greater than 63 V. Operating temperature range must encompass -40°C to 85°C. Lifetime rating must be 2000 hours at 85°C or greater. Package configuration must be radial, can snap-in with identical physical dimensions (1.181" diameter, 1.457" maximum height). Mounting type must be through-hole. Polarization must be polar. RoHS3 compliance is required.

The substitute part ELH478M080AS3AA meets all substitution criteria with the exception of rated voltage, which is elevated to 80 V. This voltage increase does not compromise compatibility; it represents an upgrade that enhances circuit reliability by providing additional voltage margin.

Parameter Comparison

Engineering Selection Recommendations

The ELH478M080AS3AA is a direct substitute for the obsolete MALIEYN07BA447J42K. Both components maintain identical capacitance, tolerance, temperature operating range, and physical dimensions. The substitute part is manufactured by KEMET, an active producer with established supply availability (274,082 units in stock), compared to the original part's obsolete status.

The rated voltage increase from 63 V to 80 V in the substitute part does not introduce compatibility issues. This voltage elevation provides additional design margin and enhances circuit reliability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. Both components carry identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the ELH478M080AS3AA replace the MALIEYN07BA447J42K in existing designs?

A: Yes. The substitute part maintains identical capacitance (4700 µF), tolerance (±20%), operating temperature range (-40°C to 85°C), lifetime rating (2000 hours at 85°C), and physical dimensions (1.181" diameter, 1.457" height). The rated voltage increase from 63 V to 80 V is compatible with circuits designed for the original part.

Q: What is the significance of the voltage rating difference?

A: The substitute part's 80 V rating exceeds the original 63 V specification. This represents an upgrade that provides additional voltage margin without affecting circuit operation. The substitute part will function correctly in any application where the original 63 V part was specified.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical package dimensions: 1.181 inches (30.00 mm) diameter and 1.457 inches (37.00 mm) maximum seated height. Both use radial, can snap-in configuration with through-hole mounting. Direct mechanical substitution is possible without PCB redesign.

Q: What is the availability status of each part?

A: The original MALIEYN07BA447J42K is obsolete with limited remaining inventory (1,023 units). The substitute ELH478M080AS3AA is active production with substantial availability (274,082 units in stock), ensuring long-term procurement viability.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected. Both carry identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications, satisfying regulatory compliance for equivalent applications.
