Engineering Selection Recommendations

Both substitute parts satisfy the electrical and mechanical requirements for direct replacement of the MALSECV00AG347EARK. Selection between 477AXZ025M and 477SVH025MGE depends on application-specific considerations:

477AXZ025M provides extended operating temperature range (-55°C to 105°C) and is available in Tape & Reel packaging, suitable for high-volume automated assembly. This part exhibits slightly elevated ESR (564 mOhm) and reduced ripple current capacity (425 mA @ 120 Hz) compared to the original specification.

477SVH025MGE maintains the original operating temperature range (-40°C to 105°C) and matches the original ripple current specification (450 mA @ 120 Hz). ESR is 560 mOhm, comparable to 477AXZ025M. This part is optimized for bypass and decoupling applications.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with modern manufacturing processes and long-term reliability. Active product status guarantees continued availability and supply chain support.

Frequently Asked Questions (FAQ)

Q: Can 477AXZ025M and 477SVH025MGE be used interchangeably with MALSECV00AG347EARK?

A: Both parts meet all mandatory electrical and mechanical parameters. Selection depends on application requirements. 477AXZ025M offers extended temperature range; 477SVH025MGE matches original ripple current specifications more closely.

Q: What is the impact of ESR differences between the original and substitute parts?

A: The original part specifies 450 mOhm ESR @ 120 Hz. Substitutes measure 560–564 mOhm. This 24% increase affects impedance characteristics in high-frequency filtering applications. Verify ESR performance against circuit requirements before selection.

Q: Are there height clearance concerns with substitute parts?

A: The original part height is 10.50 mm maximum. 477AXZ025M reaches 10.60 mm; 477SVH025MGE reaches 10.80 mm. Both remain within typical PCB assembly tolerances. Confirm clearance in space-constrained designs.

Q: Do substitute parts require different PCB land patterns?

A: No. All three parts use identical surface mount land size (10.30 mm × 10.30 mm). PCB footprints are directly compatible.

Q: What packaging options are available for production?

A: 477AXZ025M is supplied in Tape & Reel format, standard for automated SMD assembly. 477SVH025MGE packaging specification is not detailed in available data. Confirm packaging availability with supplier for production requirements.

Q: Are compliance certifications identical across all three parts?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Regulatory requirements are satisfied by any substitute selection.
