ALC70E272FP400 Equivalent & Substitute Parts

Part Overview

The ALC70E272FP400 is a 2700 µF, 400 V aluminum electrolytic capacitor manufactured by KEMET in the ALC70 series. This radial, can-style snap-in capacitor with 4 leads is designed for general-purpose applications requiring high capacitance and voltage ratings. The part is Active in product status and fully compliant with RoHS3 and REACH regulations. Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements permit functional alternatives.

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Capacitance value: 2700 µF (exact match required)
• Voltage rating: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - Snap-In - 4 Lead (exact match required)
• Lead spacing: 0.886" (22.50 mm) (exact match required)
• Physical dimensions: 1.772" Dia (45.00 mm) and 4.213" (107.00 mm) height (exact match required)
• Mounting type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Performance Parameters (Allowable Variation):

• ESR @ 100Hz: Substitute parts must not exceed the main part specification
• Lifetime @ 85°C: Substitute parts must meet or exceed 18000 hours
• Ripple current ratings: Substitute parts must meet or exceed specified values
• Operating temperature range: Substitute parts must cover or exceed -40°C ~ 85°C

The substitute part ALC70C272FP400 meets all mandatory equivalence criteria and maintains performance specifications within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both ALC70E272FP400 and ALC70C272FP400 are Active products manufactured by KEMET within the ALC70 series. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

The substitute part ALC70C272FP400 demonstrates electrical and mechanical equivalence to the main part ALC70E272FP400. The ESR specification of the substitute part (54.78 mOhm @ 100Hz) is marginally lower than the main part (55 mOhm @ 100Hz), which represents an improvement in performance characteristics. All other electrical parameters, including capacitance, voltage rating, lifetime, ripple current ratings, and impedance, are identical between the two parts.

Physical compatibility is confirmed: both parts share identical lead spacing (0.886" / 22.50 mm), diameter (1.772" / 45.00 mm), height (4.213" / 107.00 mm), and package configuration (Radial, Can - Snap-In - 4 Lead). Both are through-hole mounted components suitable for identical PCB footprints.

Selection between these two parts may be based on inventory availability, procurement lead time, or supply chain considerations, as both parts satisfy the same electrical and mechanical requirements.

Frequently Asked Questions (FAQ)

Q: Can ALC70C272FP400 be used as a direct replacement for ALC70E272FP400?

A: Yes. Both parts are manufactured by KEMET, share identical capacitance (2700 µF), voltage rating (400 V), tolerance (±20%), package configuration (Radial, Can - Snap-In - 4 Lead), and physical dimensions. All electrical performance parameters are equivalent or superior in the substitute part.

Q: What is the difference between ALC70E272FP400 and ALC70C272FP400?
