Substitute Part Grouping Explanation

Substitution of the DCMC243T200DF2B is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

Capacitance: 24000 µF (exact match required)
Voltage Rating: 200 V (exact match required)
Tolerance: -10%, +50% (exact match required)
Operating Temperature: -40°C to 85°C (exact match required)
Lifetime: 2000 Hrs @ 85°C (exact match required)
Polarization: Polar (exact match required)

Mechanical Parameters:

Package Type: Radial, Can - Screw Terminals (exact match required)
Mounting: Chassis Mount (exact match required)
Lead Spacing: 1.250" (31.75 mm) (exact match required)
Physical Dimensions: 3.000" Dia × 5.687" Height (exact match required)

Compliance Parameters:

RoHS Status: ROHS3 Compliant (exact match required)
REACH Status: REACH Unaffected (exact match required)

Substitute parts must satisfy all parameters listed above. Parts with differing ESR specifications, ripple current ratings, or any other electrical or mechanical deviation are not considered equivalent substitutes.
