Substitute Part Grouping Explanation

Substitution eligibility for the DCMC643M063CC2F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance: 64000 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 120Hz: 13.8 mOhm (exact match required)
• Lifetime @ 85°C: 2000 Hrs (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)

Mechanical Parameters:

• Lead Spacing: 1.125" / 28.58 mm (exact match required)
• Diameter: 2.500" / 63.50 mm (exact match required)
• Height - Seated (Max): 4.125" / 104.78 mm (exact match required)
• Package / Case: Radial, Can - Screw Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Polarization: Polar (exact match required)

Substitute parts must originate from the same DCMC series and maintain identical electrical performance and physical dimensions to ensure direct replacement without circuit modification or mechanical rework.

Parameter Comparison

Engineering Selection Recommendations

Both the DCMC643M063CC2F and DCMC643M063CC2B are Active products manufactured by Cornell Dubilier Electronics within the DCMC series. Both components satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The DCMC643M063CC2B differs from the main part only in packaging designation (Bulk versus standard packaging). This distinction does not affect electrical performance, mechanical compatibility, or functional interchangeability. Both parts maintain identical electrical specifications, physical dimensions, and environmental ratings.

Selection between these parts is determined by procurement requirements and packaging preferences rather than technical performance criteria. Both are suitable for direct substitution in chassis-mounted applications requiring 64000 µF capacitance at 63 V with screw terminal connections.
