Substitute Part Grouping Explanation

Substitution of the ALC70D471CF400 is based on strict equivalence of the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 470 µF (exact match required)
• Rated voltage: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 290 mOhm (within manufacturing tolerance)
• Lifetime @ 85°C: 13,000 Hrs (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Ripple current specifications: 2.29 A @ 100 Hz and 5.73 A @ 10 kHz (exact match required)

Mechanical Equivalence Criteria:

• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Physical dimensions: 1.181" Dia (30.00 mm), Height 2.047" (52.00 mm) (exact match required)

Compliance Equivalence Criteria:

• RoHS3 Compliant status (exact match required)
• REACH Unaffected status (exact match required)

The substitute part ALC70A471CF400 meets all equivalence criteria and is therefore a direct parametric equivalent.

Engineering Selection Recommendations

Primary Selection: ALC70D471CF400

The ALC70D471CF400 is the specified part number and should be used as the first choice when available. Current inventory status shows 1,186 pieces in stock.

Substitute Selection: ALC70A471CF400

The ALC70A471CF400 is a direct parametric equivalent and may be selected when the primary part is unavailable. Both parts are manufactured by KEMET within the same ALC70 series and maintain identical electrical, mechanical, and compliance specifications. The ESR variance (290 mOhm versus 289.9 mOhm) is within manufacturing tolerance and does not affect functional equivalence. Current inventory status shows 1,046 pieces in stock.

Compliance Verification

Both parts maintain Active product status, ROHS3 compliance, and REACH Unaffected designation. No additional compliance verification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can ALC70A471CF400 be used as a direct replacement for ALC70D471CF400?

A: Yes. The ALC70A471CF400 is a parametric equivalent with identical capacitance (470 µF), voltage rating (400 V), tolerance (±20%), lifetime (13,000 Hrs @ 85°C), ripple current specifications, and mechanical dimensions. Both parts are KEMET ALC70 series components with Through Hole, Radial Can Snap-In packaging.

Q: Are there any electrical performance differences between these parts?

A: The ESR @ 100Hz differs by 0.1 mOhm (290 mOhm versus 289.9 mOhm), which is within standard manufacturing tolerance for aluminum electrolytic capacitors and does not constitute a functional difference.

Q: Do both parts fit the same PCB footprint?

A: Yes. Both parts have identical lead spacing (0.394" / 10.00 mm), diameter (1.181" / 30.00 mm), and maximum seated height (2.047" / 52.00 mm). PCB layout and mounting hole patterns are interchangeable.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across -40°C to 85°C. The rated lifetime of 13,000 hours applies at the maximum operating temperature of 85°C.

Q: Are these parts RoHS compliant?

A: Yes. Both ALC70D471CF400 and ALC70A471CF400 are ROHS3 Compliant and REACH Unaffected.

Q: What is the ripple current rating?

A: Both parts are rated for 2.29 A @ 100 Hz (low frequency) and 5.73 A @ 10 kHz (high frequency).
