The MAL215933471E3 manufactured by Vishay Beyschlag/Draloric/BC Components meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MAL215933471E3 is qualified as a direct parametric equivalent to the 477LMX250M2CF based on matching electrical specifications, mechanical dimensions, and compliance certifications. Both parts are Active status products with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory compatibility in current and future applications.

The substitute part demonstrates equivalent performance characteristics within the specified operating envelope. ESR values are comparable across the specified frequency ranges, and ripple current ratings are within acceptable tolerance bands for general-purpose applications. Mechanical interchangeability is confirmed through identical lead spacing, case diameter, and seated height specifications, enabling direct board-level substitution without layout modifications.

Selection between the main part and substitute should be based on availability, procurement lead time, and inventory requirements rather than technical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can the MAL215933471E3 be used as a direct replacement for the 477LMX250M2CF on existing circuit boards?

A: Yes. Both parts share identical mechanical dimensions (lead spacing, case diameter, and height), identical electrical ratings (470 µF, 250 V, ±20% tolerance), and identical operating temperature range (-25°C to 105°C). Direct board-level substitution is supported without layout or design modifications.

Q: Are there differences in ESR performance between these two parts?

A: ESR values are specified at different reference frequencies (529.1 mOhm @ 120 Hz for the 477LMX250M2CF versus 505 mOhm @ 100 Hz for the MAL215933471E3). These measurements reflect manufacturer test conditions and are comparable within the performance envelope for general-purpose applications. Both parts meet the 5000-hour lifetime specification at 105°C.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 477LMX250M2CF and MAL215933471E3 are RoHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: What is the significance of the snap-in package style?

A: The snap-in package indicates a mechanical retention feature on the capacitor can that engages with corresponding slots on the PCB. This design provides mechanical stability during assembly and operation. Both substitute parts use identical snap-in package geometry, ensuring compatibility with existing board designs.

Q: Are there any application restrictions for the substitute part?

A: No application restrictions exist beyond those specified for the original part. Both capacitors are rated for general-purpose applications across the -25°C to 105°C operating range with 5000-hour lifetime at 105°C. Substitution is valid for all applications where the 477LMX250M2CF is specified.
