Substitute Part Grouping Explanation

Substitution of the ALC70D153CD040 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 15000 µF (exact match required)
• Voltage rating: 40 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 48 mOhm nominal (minor variance acceptable within engineering tolerance)
• Lifetime @ 85°C: 13000 Hrs (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Ripple current specifications: 6.41 A @ 100 Hz and 8.34 A @ 10 kHz (exact match required)

Mechanical Parameters:

• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Diameter: 1.181" (30.00 mm) (exact match required)
• Height - Seated (Max): 1.654" (42.00 mm) (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Polarization: Polar (exact match required)

The ALC70A153CD040 qualifies as a parametric equivalent substitute based on full alignment with all critical electrical, mechanical, and compliance parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

Both the ALC70D153CD040 and ALC70A153CD040 maintain Active product status from KEMET, ensuring ongoing manufacturer support and supply availability. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications.

The ALC70A153CD040 demonstrates ESR variance of 0.33 mOhm above the main part specification (48.33 mOhm versus 48 mOhm @ 100Hz). This variance remains within acceptable engineering tolerance for aluminum electrolytic capacitor technology and does not impact functional equivalence across the specified electrical and mechanical parameters.

Selection between these parts should be based on availability, procurement lead time, and inventory position. Both parts are suitable for direct substitution in applications requiring 15000 µF, 40 V aluminum electrolytic capacitors with snap-in mounting configuration and through-hole lead spacing of 10.00 mm.

Frequently Asked Questions (FAQ)

Q: Can the ALC70A153CD040 be used as a direct replacement for the ALC70D153CD040?

A: Yes. The ALC70A153CD040 is a parametric equivalent substitute. All critical electrical parameters (capacitance, voltage rating, tolerance, ESR, lifetime, ripple current), mechanical dimensions (lead spacing, diameter, height), and compliance certifications (RoHS3, REACH) are identical or equivalent between the two parts.

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

A: The ESR @ 100Hz differs by 0.33 mOhm (48 mOhm for ALC70D153CD040 versus 48.33 mOhm for ALC70A153CD040). This variance is within normal manufacturing tolerance for aluminum electrolytic capacitors and does not affect functional performance or circuit compatibility.

Q: Are both parts suitable for the same PCB layout and footprint?

A: Yes. Both parts share identical mechanical specifications: 0.394" (10.00 mm) lead spacing, 1.181" (30.00 mm) diameter, and 1.654" (42.00 mm) maximum seated height. Both use radial, can snap-in package configuration with through-hole mounting. PCB layouts and footprints are directly interchangeable.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both the ALC70D153CD040 and ALC70A153CD040 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for industrial applications.

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

A: The base product numbers (ALC70D versus ALC70A) indicate different internal design revisions or manufacturing generations within the ALC70 series. Both maintain identical electrical and mechanical specifications for the 15000 µF, 40 V configuration, ensuring functional equivalence.

Q: Are there any temperature or ripple current limitations when substituting between these parts?

A: No. Both parts operate across the identical temperature range (-40°C ~ 85°C) and support identical ripple current specifications (6.41 A @ 100 Hz and 8.34 A @ 10 kHz). Thermal and current handling characteristics are equivalent.
