Substitute Part Grouping Explanation

Substitution of the ALC80D331CD350 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part ALC80A331CD350 qualifies as a parametric equivalent because it maintains identical specifications in the following key areas:

Electrical Parameters (Must Match Exactly):

• Capacitance: 330 µF
• Rated Voltage: 350 V
• Tolerance: ±20%
• ESR @ 100Hz: 411 mOhm
• Lifetime @ 105°C: 7000 Hrs
• Operating Temperature Range: -40°C to 105°C
• Ripple Current @ 100 Hz: 1.85 A
• Ripple Current @ 10 kHz: 5.21 A

Mechanical Parameters (Must Match Exactly):

• Lead Spacing: 10.00 mm
• Diameter: 30.00 mm
• Height - Seated (Max): 42.00 mm
• Mounting Type: Through Hole
• Package / Case: Radial, Can - Snap-In

Compliance & Regulatory (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Manufacturer: KEMET

The only difference between the main part and substitute is the base product number designation (ALC80D versus ALC80A), which does not affect electrical performance, thermal characteristics, or physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the ALC80D331CD350 and ALC80A331CD350 are Active products manufactured by KEMET with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements, as they are electrically and mechanically identical. Both parts are suitable for direct substitution in through-hole PCB applications requiring 330 µF capacitance at 350 V with snap-in mounting. The identical ESR, ripple current ratings, and thermal lifetime specifications ensure equivalent performance in filtering, energy storage, and power conditioning circuits. Compliance certifications are maintained across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can ALC80A331CD350 be used as a direct replacement for ALC80D331CD350?
