Engineering Selection Recommendations

B43644B9477M000 (EPCOS - TDK Electronics)

This substitute part provides a 50 V voltage rating increase (400 V versus 350 V) while maintaining identical physical dimensions and lead spacing. The ESR is significantly reduced to 210 mOhm at 100 Hz, representing a 70% improvement over the original part. Lifetime is extended to 5000 Hrs at 105°C. Operating temperature range expands to -40°C ~ 105°C. Both parts maintain ROHS3 compliance and REACH unaffected status. This part is suitable for applications where improved thermal performance and extended operational life are beneficial within the same form factor.

ELHS451VSN471MA35S (Chemi-Con)

This substitute part provides a 100 V voltage rating increase (450 V versus 350 V) while maintaining identical lead spacing and diameter. Height increases by 0.50 mm (37.50 mm versus 37.00 mm), which may require verification in space-constrained applications. Lifetime is extended to 5000 Hrs at 105°C. Operating temperature range expands to -40°C ~ 105°C. RoHS compliance is maintained. This part is suitable for applications requiring higher voltage margin and extended operational life, provided the additional 0.50 mm height does not conflict with mechanical constraints.

Both substitute parts are Active status products with current inventory availability and maintain regulatory compliance equivalent to or exceeding the original part.

Frequently Asked Questions (FAQ)

Q: Can B43644B9477M000 be used as a direct replacement for SLP471M350H5P3?

A: Yes. Both parts share identical capacitance (470 µF), tolerance (±20%), lead spacing (10.00 mm), diameter (35.00 mm), height (37.00 mm), package type (Radial, Can - Snap-In), and mounting type (Through Hole). The 400 V rating of B43644B9477M000 exceeds the 350 V requirement, and the reduced ESR (210 mOhm) provides improved performance. Both are ROHS3 compliant and REACH unaffected.

Q: Can ELHS451VSN471MA35S be used as a direct replacement for SLP471M350H5P3?

A: Yes, with one mechanical consideration. All electrical parameters match the substitution criteria. The height is 37.50 mm versus 37.00 mm for the original part, representing a 0.50 mm increase. Verify that this additional height does not conflict with mechanical clearances in your application before implementation.

Q: What is the significance of the ESR difference between these parts?

A: ESR (Equivalent Series Resistance) directly affects ripple current handling and thermal performance. Lower ESR values indicate reduced internal resistance and improved efficiency. B43644B9477M000 at 210 mOhm provides superior performance compared to SLP471M350H5P3 at 706 mOhm. ELHS451VSN471MA35S does not specify ESR in the provided data.

Q: Are there temperature range differences I should consider?

A: Yes. SLP471M350H5P3 operates from -25°C to 105°C. Both substitute parts expand the lower temperature limit to -40°C, providing wider operational range. This expansion does not create compatibility issues and may benefit applications in cold environments.

Q: Do all three parts meet current regulatory requirements?

A: Yes. SLP471M350H5P3 is ROHS3 compliant and REACH unaffected. B43644B9477M000 maintains ROHS3 compliance and REACH unaffected status. ELHS451VSN471MA35S is RoHS compliant and REACH unaffected. All three parts meet current regulatory standards for electronic component use.

Q: What is the difference in lifetime specifications?

A: SLP471M350H5P3 is rated for 3000 Hrs at 105°C. Both substitute parts extend this to 5000 Hrs at 105°C, representing a 67% increase in rated operational life. Extended lifetime indicates improved reliability in high-temperature applications.

Q: Can I use these parts interchangeably in my PCB design?

A: Yes, provided mechanical constraints are satisfied. All three parts use identical lead spacing (10.00 mm) and diameter (35.00 mm), ensuring PCB footprint compatibility. The height difference of 0.50 mm for ELHS451VSN471MA35S requires verification against available clearance above the component.
