Cornell Dubilier 225AXZ050M Equivalent & Substitute Parts

Part Overview

The Cornell Dubilier 225AXZ050M is a 2.2 µF, 50 V aluminum electrolytic capacitor in surface mount radial can package, rated for 2000 hours at 105°C. This component is designed for bypass and decoupling applications in electronic circuits. The part maintains Active product status and is ROHS3 compliant. Identification of equivalent substitute parts becomes necessary for component sourcing optimization, supply chain continuity, inventory management, and design flexibility when the primary part is unavailable or when alternative options provide superior electrical performance characteristics within the same application envelope.

Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute parts for the Cornell Dubilier 225AXZ050M are identified based on strict alignment of the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

• Capacitance: 2.2 µF (exact value)
• Voltage Rating: 50 V (minimum required)
• Tolerance: ±20% or tighter
• Mounting Type: Surface Mount
• Package Type: Radial, Can - SMD
• Operating Temperature Range: -55°C ~ 105°C minimum
• Lifetime: 2000 Hrs @ 105°C minimum
• Polarization: Polar

The substitute part MAL215371228E3 (Vishay Beyschlag/Draloric/BC Components, 153 CRV series) satisfies all mandatory parameters while offering improved electrical characteristics in terms of equivalent series resistance (ESR) performance.

Parameter Comparison

Engineering Selection Recommendations

Both the Cornell Dubilier 225AXZ050M and Vishay MAL215371228E3 are Active product status components with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing requirements. The MAL215371228E3 demonstrates superior ESR performance (12Ohm @ 100kHz compared to 90.429Ohm @ 120Hz), which benefits high-frequency filtering applications and reduces thermal stress. The height difference (0.209" vs 0.220") represents a 0.011" reduction with the substitute, providing marginal PCB layout advantages. Both parts share identical land size requirements, eliminating PCB redesign considerations. Selection between these parts should be based on supply chain availability and application-specific ESR performance requirements at the relevant frequency of operation.

Frequently Asked Questions (FAQ)

Q: Can MAL215371228E3 be directly substituted for 225AXZ050M in all applications? A: Direct substitution is permissible where the application operates within -55°C to 105°C and requires minimum 2000 hour lifetime at 105°C. The reduced ESR of the substitute part (12Ohm @ 100kHz vs 90.429Ohm @ 120Hz) is electrically favorable and introduces no compatibility issues. The height difference of 0.011" is within typical PCB clearance tolerances.

Q: What are the critical parameters that define substitutability? A: Critical parameters are capacitance (2.2 µF exact), voltage rating (50 V minimum), tolerance (±20% maximum), package type (Radial Can SMD with 0.169" x 0.169" land size), and thermal rating (2000 Hrs @ 105°C). Deviations from these parameters eliminate interchangeability.

Q: Does the ESR difference affect circuit performance? A: The substitute part's lower ESR (12Ohm @ 100kHz) provides improved high-frequency filtering characteristics and reduced voltage ripple. This represents an electrical enhancement for bypass and decoupling applications, with no negative performance impact on the primary circuit function.

Q: Are there packaging or ordering considerations? A: The Cornell Dubilier 225AXZ050M information does not specify packaging format. The Vishay MAL215371228E3 is supplied in Tape & Reel (TR) format, standard for surface mount production. Verify packaging compatibility with assembly requirements before procurement.

Q: What certifications and compliance standards apply? A: Both parts are ROHS3 compliant, REACH unaffected, and designated EAR99 for export control purposes. These certifications ensure compatibility with current regulatory requirements for commercial electronics manufacturing.
