The ALC70A471EB350 meets all substitution criteria and is classified as a parametric equivalent within the same ALC70 series family.

Parameter Comparison

Engineering Selection Recommendations

Both the ALC70D471EB350 and ALC70A471EB350 are active production parts manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically interchangeable based on all provided specifications. The ESR differential (312 mOhm versus 311.7 mOhm) is within normal manufacturing tolerance and does not constitute a functional difference for general-purpose applications.

Selection between these parts should be based on:

1. Inventory Availability: ALC70D471EB350 has 273,782 pcs in stock; ALC70A471EB350 has 1,061 pcs in stock.
2. Supply Chain Requirements: Use the substitute part when the primary part is unavailable from your procurement source.
3. Regulatory Compliance: Both parts satisfy identical compliance requirements (ROHS3, REACH).
4. Circuit Board Layout: Both parts occupy identical physical footprints and mounting positions.

No additional testing or verification is required when substituting between these parts within the same application circuit.

Frequently Asked Questions (FAQ)

Q: Can ALC70A471EB350 be used as a direct replacement for ALC70D471EB350?

A: Yes. The ALC70A471EB350 is a parametric equivalent with identical electrical ratings (470 µF, 350 V, ±20%), identical mechanical dimensions (40.00 mm diameter, 32.00 mm height, 10.00 mm lead spacing), and identical performance specifications (18000 Hrs @ 85°C, 2.29 A @ 100 Hz ripple current, 5 A @ 10 kHz ripple current). Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the difference between ALC70D and ALC70A?

A: The ALC70D and ALC70A designations represent different product variants within the ALC70 series. For the 470 µF, 350 V configuration, both variants meet identical electrical and mechanical specifications. The ESR values are functionally equivalent (312 mOhm versus 311.7 mOhm).

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical lead spacing (0.394" / 10.00 mm), diameter (1.575" / 40.00 mm), and maximum seated height (1.260" / 32.00 mm). Both use radial, can-style snap-in packaging with through-hole mounting. No PCB layout modifications are required.

Q: Do both parts have the same ripple current ratings?

A: Yes. Both the ALC70D471EB350 and ALC70A471EB350 are rated for 2.29 A ripple current at 100 Hz and 5 A ripple current at 10 kHz.

Q: Are there any compliance differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory status (ECCN: EAR99, HTSUS: 8532.22.0055).

Q: Which part should I specify if both are available?

A: Either part is acceptable for new designs and existing applications. Selection should be based on procurement availability and supply chain preferences. Both parts are active production items from KEMET.
