Substitute Part Grouping Explanation

Substitution for the MALSECA00AG347EARK is determined by strict equivalence in the following core parameters: capacitance value (470 µF), voltage rating (25 V), tolerance (±20%), polarization (polar), package type (radial can SMD), and physical dimensions compatible with the original land pattern (0.406" L x 0.406" W). All substitute parts must maintain surface mount compatibility and RoHS3 compliance.

The substitute parts are grouped into two categories:

Direct Equivalent: Parts with matching electrical performance at the original operating temperature specification (2000 Hrs @ 85°C).

Upgraded Performance: Parts with enhanced temperature ratings (2000 Hrs @ 105°C) and extended operating temperature ranges, providing superior reliability margins while maintaining full backward compatibility with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

477SML025M serves as the direct equivalent for applications requiring identical electrical and thermal specifications. This part maintains the 2000 Hrs @ 85°C lifetime rating and -40°C ~ 85°C operating range of the original MALSECA00AG347EARK. The 477SML025M is currently in active production status, ensuring long-term availability. Note that the surface mount land size differs (0.394" x 0.394" versus 0.406" x 0.406"), requiring PCB layout verification for compatibility.

477AXZ025M and 477SVH025MGE are upgraded alternatives offering extended temperature performance with 2000 Hrs @ 105°C lifetime ratings. Both parts maintain full electrical equivalence at the 25 V, 470 µF specification while providing superior thermal margins. The 477AXZ025M features the widest operating temperature range (-55°C ~ 105°C) and is available in Tape & Reel packaging. The 477SVH025MGE is optimized for bypass and decoupling applications with enhanced ripple current handling at high frequency (675 mA @ 100 kHz). Both upgraded parts use the original land size (0.406" x 0.406"), ensuring direct PCB compatibility.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, meeting regulatory and environmental requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can 477SML025M be used as a direct replacement for MALSECA00AG347EARK?

A: Yes, 477SML025M is electrically equivalent with matching capacitance (470 µF), voltage rating (25 V), tolerance (±20%), and thermal specifications (2000 Hrs @ 85°C). However, the surface mount land size differs (0.394" x 0.394" versus 0.406" x 0.406"), requiring PCB layout verification before implementation.

Q: What are the advantages of using 477AXZ025M or 477SVH025MGE over 477SML025M?

A: Both upgraded parts provide enhanced thermal performance with 2000 Hrs @ 105°C lifetime ratings and extended operating temperature ranges. This delivers superior reliability margins for applications subject to elevated ambient temperatures or thermal cycling. Both parts use the original land size (0.406" x 0.406"), ensuring direct PCB compatibility without layout modifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts (477SML025M, 477AXZ025M, and 477SVH025MGE) are ROHS3 compliant with MSL 1 rating, meeting regulatory requirements equivalent to the original MALSECA00AG347EARK.

Q: What is the difference between 477AXZ025M and 477SVH025MGE?

A: Both parts share identical electrical specifications (470 µF, 25 V, ±20%) and thermal ratings (2000 Hrs @ 105°C). The 477AXZ025M operates from -55°C ~ 105°C and is available in Tape & Reel packaging. The 477SVH025MGE operates from -40°C ~ 105°C and is optimized for bypass and decoupling applications with higher ripple current at high frequency (675 mA @ 100 kHz versus 850 mA @ 100 kHz for 477AXZ025M).

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed for all substitute parts at the 470 µF, 25 V specification. Physical compatibility requires verification of surface mount land size: 477SML025M uses 0.394" x 0.394" land size, while 477AXZ025M and 477SVH025MGE use 0.406" x 0.406" land size matching the original part. Height differences (0.413" to 0.425" seated height) must be evaluated for clearance in confined PCB assemblies.
