Key Parameters

Substitute Part Grouping Explanation

Substitution of the MALSECV00AF247FARK is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 47 µF (exact match required)
• Tolerance: ±20% (electrical performance equivalence)
• Package type: Radial, Can - SMD (mechanical and thermal compatibility)
• Physical dimensions: 0.315" diameter × 0.413" height (PCB footprint compatibility)
• Mounting type: Surface Mount (assembly process compatibility)
• Polarization: Polar (circuit function requirement)

Allowable Upgrade Parameters:

• Voltage rating: May be equal or higher than 35 V (backward compatible)
• ESR: Lower values acceptable (improved performance)
• Lifetime @ 105°C: Equal or longer acceptable (improved reliability)
• Operating temperature range: Equal or wider acceptable (expanded operating envelope)
• Product status: Active preferred over obsolete (supply continuity)

The substitute part MAL215371479E3 meets all mandatory matching criteria while providing upgrades in voltage rating, ESR, lifetime, and product status.

Parameter Comparison

Engineering Selection Recommendations

The MAL215371479E3 is a direct functional substitute for the MALSECV00AF247FARK. Both components maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1 - Unlimited). The substitute part provides superior electrical characteristics through reduced ESR and extended operational lifetime, while maintaining identical physical footprint and mounting compatibility.

The transition from an obsolete part to an active production part ensures long-term component availability and supply chain stability. The higher voltage rating (50 V vs. 35 V) provides additional design margin without affecting circuit functionality in applications originally specified for 35 V operation.

Frequently Asked Questions (FAQ)

Q: Can MAL215371479E3 be used as a direct replacement for MALSECV00AF247FARK?

A: Yes. Both parts share identical capacitance (47 µF), tolerance (±20%), package type (Radial, Can - SMD), physical dimensions (0.315" diameter × 0.413" height), and mounting configuration (Surface Mount). The substitute part is electrically and mechanically compatible with existing PCB designs.

Q: What are the key differences between these two parts?

A: The MAL215371479E3 provides three upgrades: higher voltage rating (50 V vs. 35 V), lower ESR (500 mOhm @ 100kHz vs. 3.67 Ohm @ 120Hz), and extended lifetime (3000 hours vs. 2000 hours at 105°C). Additionally, the substitute part is in active production status, ensuring supply availability.

Q: Will the higher voltage rating of MAL215371479E3 affect circuit performance?

A: No. A higher voltage rating does not negatively impact circuit function. The component will operate correctly in applications originally designed for 35 V operation. The increased voltage margin provides additional design safety.

Q: Are the physical footprints identical?

A: Yes. Both parts have identical surface mount land sizes and overall dimensions (0.315" diameter × 0.413" height), ensuring direct PCB compatibility without layout modifications.

Q: What is the significance of the lower ESR in the substitute part?

A: Lower ESR (Equivalent Series Resistance) reduces heat generation and improves high-frequency performance. The MAL215371479E3's ESR of 500 mOhm at 100kHz represents improved electrical efficiency compared to the original part's 3.67 Ohm at 120Hz.

Q: Are both parts RoHS compliant?

A: Yes. Both MALSECV00AF247FARK and MAL215371479E3 are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
