ALS70H363MF100 Equivalent & Substitute Parts

Part Overview

The ALS70H363MF100 is a 36000 µF, 100 V aluminum electrolytic capacitor manufactured by KEMET in the ALS70 series. This radial, can-style capacitor with screw terminals is designed for general-purpose applications requiring high capacitance values at moderate voltage ratings. The part is currently Active in product status and maintains full RoHS3 compliance. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require component flexibility within equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the ALS70H363MF100 are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Critical Parameters for Substitution:

• Capacitance value: 36000 µF (exact match required)
• Voltage rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 14 mOhm (exact match required)
• Lifetime @ 85°C: 19000 Hrs (exact match required)
• Operating temperature range: -40°C to 85°C (exact match required)
• Ripple current specifications @ 100 Hz and 10 kHz (exact match required)
• Impedance: 12 mOhms (exact match required)
• Physical dimensions and lead spacing (exact match required)
• Mounting type: Chassis Mount (exact match required)
• Package type: Radial, Can - Screw Terminals (exact match required)

The ALS70A363MF100 meets all substitution criteria as a parametric equivalent within the KEMET ALS70 series, differing only in the base product designation (ALS70A versus ALS70H). Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70H363MF100 and ALS70A363MF100 are Active products manufactured by KEMET with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and inventory status rather than electrical or mechanical performance differences.

The ALS70H363MF100 maintains current inventory of 1040 pieces. The ALS70A363MF100 provides an alternative source with 973 pieces in stock. Both parts satisfy identical circuit requirements and board-level integration specifications. Component selection should prioritize availability and lead time requirements for the specific procurement cycle.

Compliance certifications (RoHS3, REACH unaffected, EAR99 ECCN classification, HTSUS 8532.22.0085) are equivalent across both part numbers, ensuring regulatory alignment for applications in regulated industries.

Frequently Asked Questions (FAQ)

Q: Can ALS70A363MF100 be used as a direct replacement for ALS70H363MF100?

A: Yes. Both parts are parametric equivalents with identical capacitance (36000 µF), voltage rating (100 V), ESR (14 mOhm @ 100Hz), lifetime (19000 Hrs @ 85°C), ripple current specifications, impedance, physical dimensions, and mounting characteristics. The difference in base product designation (ALS70A versus ALS70H) does not affect electrical performance or mechanical compatibility.

Q: Are the physical dimensions identical between these two part numbers?

A: Yes. Both parts share identical dimensions: 66.00 mm diameter, 107.00 mm maximum seated height, and 28.50 mm lead spacing. Screw terminal positioning and chassis mount configuration are equivalent, ensuring identical PCB layout and mechanical integration.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both ALS70H363MF100 and ALS70A363MF100 are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.22.0085. Regulatory and environmental compliance is equivalent.

Q: What is the difference between these two part numbers?

A: The parts differ only in the base product designation within the ALS70 series (H versus A variant). All electrical specifications, thermal characteristics, mechanical dimensions, and compliance certifications are identical. The distinction reflects internal KEMET product line organization and does not impact circuit performance.

Q: Can these capacitors be used interchangeably in existing designs?

A: Yes. No design modifications are required. Both parts operate within the same temperature range (-40°C to 85°C), support identical ripple current loads at 100 Hz (24.5 A) and 10 kHz (27.7 A), and maintain equivalent ESR and impedance characteristics. Screw terminal connections and chassis mount configuration are identical.
