Substitute Part Grouping Explanation

Substitute parts for the ALC70D562BB040 are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 5600 µF (exact match required)
• Voltage rating: 40 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating temperature range: -40°C to 85°C (exact match required)
• Lifetime specification: 10000 Hrs @ 85°C (exact match required)

Mechanical Equivalence Criteria:

• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 10.00 mm (exact match required)
• Physical dimensions: 25.00 mm diameter, 32.00 mm height seated (exact match required)
• Mounting type: Through Hole (exact match required)

Compliance Equivalence Criteria:

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

The substitute part ALC70D562BB040 differs from the main part only in ESR specification (130.8 mOhm versus 131 mOhm @ 100Hz), which falls within normal manufacturing tolerance for this component category and does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the ALC70D562BB040 and ALC70A562BB040 are Active products with full RoHS3 compliance and REACH unaffected status, making them suitable for applications requiring regulatory compliance in restricted substance directives. The parts are electrically and mechanically interchangeable within the specified parameters.

Selection between these parts should be based on:

1. Inventory Availability: Both parts maintain substantial stock levels (273,882 Pcs for ALC70D562BB040 and 273,982 Pcs for ALC70A562BB040), supporting continuous supply for production requirements.

2. ESR Performance: The ESR differential (131 mOhm versus 130.8 mOhm) is negligible and within normal manufacturing tolerance for aluminum electrolytic capacitors. This variance does not impact functional performance in general-purpose applications.

3. Compliance Requirements: Both parts satisfy identical compliance certifications, permitting direct substitution in designs requiring RoHS3 and REACH compliance.

4. PCB Layout Compatibility: Identical mechanical dimensions and lead spacing ensure direct board-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can ALC70A562BB040 be used as a direct replacement for ALC70D562BB040?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters including capacitance, voltage rating, tolerance, operating temperature range, lifetime specification, physical dimensions, and lead spacing. Both maintain Active product status with identical compliance certifications.

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

A: The ESR values (131 mOhm for ALC70D562BB040 and 130.8 mOhm for ALC70A562BB040) differ by 0.2 mOhm, representing a 0.15% variance. This difference is within normal manufacturing tolerance for aluminum electrolytic capacitors and does not affect functional performance in general-purpose applications.

Q: Are there any PCB layout considerations when substituting between these parts?

A: No. Both parts share identical mechanical specifications: 25.00 mm diameter, 32.00 mm seated height, and 10.00 mm lead spacing. Direct board-level substitution is possible without layout modifications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both ALC70D562BB040 and ALC70A562BB040 are RoHS3 Compliant and REACH Unaffected, satisfying identical regulatory requirements for restricted substance compliance.

Q: What is the difference between the base product numbers ALC70D and ALC70A?

A: The base product numbers indicate different internal design revisions within the ALC70 series. Both revisions deliver identical electrical performance and mechanical compatibility for the 5600 µF, 40 V specification. The substitution is based on parametric equivalence rather than design revision designation.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: Yes. Both parts specify identical ripple current ratings: 3.17 A @ 100 Hz and 4.09 A @ 10 kHz. They are suitable for applications within these ripple current specifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -40°C to 85°C with a rated lifetime of 10,000 hours at 85°C.
