Substitute Part Grouping Explanation

Substitution of the ALS81A133DA040 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Capacitance: 13000 µF
• Voltage Rating: 40 V
• Tolerance: ±20%
• ESR @ 100Hz: 49 mOhm
• Lifetime @ 105°C: 6000 Hrs
• Operating Temperature Range: -40°C to 105°C
• Ripple Current @ 100 Hz: 8 A
• Ripple Current @ 10 kHz: 10.4 A

Mechanical Parameters (Must Match):

• Package / Case: Radial, Can - Screw Terminals
• Mounting Type: Chassis Mount
• Lead Spacing: 12.80 mm
• Diameter: 36.00 mm
• Height - Seated (Max): 54.00 mm

Compliance & Status (Must Match):

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The ALS80A133DA040 qualifies as a parametric equivalent substitute because it maintains identical electrical performance specifications and mechanical form factor while differing only in series designation (ALS80 vs. ALS81).

Parameter Comparison

Engineering Selection Recommendations

Both the ALS81A133DA040 and ALS80A133DA040 are active production components manufactured by KEMET with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements, as all electrical performance characteristics, mechanical dimensions, and environmental ratings are identical.

The ALS80A133DA040 substitute provides equivalent functionality in all circuit applications where the ALS81A133DA040 is specified. Both components support the same ripple current ratings, ESR performance, and thermal lifetime specifications. Chassis mount installation and screw terminal connectivity are identical across both part numbers.

Component selection should prioritize inventory availability and lead time considerations, as the parametric equivalence ensures interchangeable performance in general-purpose aluminum electrolytic capacitor applications.
