Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence across electrical and mechanical parameters. For the ALS70C363MF100, the substitute part ALS70A363MF100 qualifies as a parametric equivalent based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Capacitance: 36000 µF
• Voltage Rating: 100 V
• Tolerance: ±20%
• ESR @ 100Hz: 14 mOhm
• Lifetime @ 85°C: 19000 Hrs
• Operating Temperature Range: -40°C ~ 85°C
• Ripple Current @ 100 Hz: 24.5 A
• Ripple Current @ 10 kHz: 27.7 A
• Impedance: 12 mOhms

Mechanical Parameters (Must Match Exactly):

• Lead Spacing: 28.50 mm
• Diameter: 66.00 mm
• Height - Seated (Max): 107.00 mm
• Mounting Type: Chassis Mount
• Package / Case: Radial, Can - Screw Terminals

Compliance & Certifications (Must Match):

• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)
• REACH Status: REACH Unaffected

The substitute part differs only in the base product number designation (ALS70A versus ALS70C), indicating a variant within the same KEMET ALS70 series. All critical electrical and mechanical specifications remain identical, permitting direct substitution in circuit applications.

4. Electrical Performance: Identical electrical specifications ensure equivalent circuit performance in all applications where the ALS70C363MF100 is specified.

5. Supply Chain Continuity: Either part may be selected to mitigate single-source risk or to accommodate supplier allocation constraints.

Frequently Asked Questions (FAQ)

Q: Can ALS70A363MF100 be used as a direct replacement for ALS70C363MF100?

A: Yes. The ALS70A363MF100 is a parametric equivalent with identical electrical and mechanical specifications. Direct substitution is permissible without circuit modification or re-qualification.

Q: What is the difference between the ALS70C and ALS70A designations?

A: Both designations refer to variants within the KEMET ALS70 series. The provided data indicates no functional or performance differences between these variants for the 36000 µF, 100 V configuration. The difference is a product line or manufacturing variant designation.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts have identical lead spacing (28.50 mm), diameter (66.00 mm), and maximum seated height (107.00 mm). PCB layout and mechanical mounting are interchangeable.

Q: Do both parts have the same ripple current ratings?

A: Yes. Both parts are rated for 24.5 A ripple current at 100 Hz and 27.7 A ripple current at 10 kHz. Thermal and electrical performance under ripple conditions is equivalent.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is identical.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection should be based on current inventory availability, supplier lead times, and procurement cost. Both parts carry Active product status and are suitable for long-term production use.

Q: Can these parts be mixed in the same assembly?

A: Yes. Since all electrical and mechanical parameters are identical, mixing ALS70C363MF100 and ALS70A363MF100 units in the same production batch or assembly presents no technical or functional risk.
