Key Parameters

Substitute Part Grouping Explanation

Substitution of the 23FB44225-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 22.5 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 440V AC (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)

Mechanical Parameters:

• Package type: Radial, Can (exact match required)
• Mounting configuration: Chassis Mount, Requires Holder/Bracket (exact match required)
• Termination style: Quick Connect, Disconnect (exact match required)
• Lead spacing: 0.813" (20.64mm) (exact match required)

Environmental & Compliance Parameters:

• Operating temperature range: -40°C to 70°C (exact match required)
• RoHS3 compliance (required for regulatory alignment)

Substitute parts must maintain identical electrical performance, physical footprint compatibility, and regulatory compliance. Minor dimensional variations in height are permissible when they do not affect mounting or mechanical clearance in the target application.

Parameter Comparison

Engineering Selection Recommendations

The Cornell Dubilier Electronics 23FB44225A-F is the direct active equivalent for the obsolete 23FB44225-F model. Both components are manufactured by the same supplier within the MPF series and maintain identical electrical and mechanical specifications across all critical parameters.

Substitution Basis:

The 23FB44225A-F provides functional and physical equivalence with the following advantages:

Frequently Asked Questions (FAQ)

Q: Can the 23FB44225A-F be used as a direct replacement for the 23FB44225-F in existing equipment?

A: Yes. The 23FB44225A-F is a direct equivalent. Both parts share identical electrical ratings (22.5 µF, 440V AC, ±10% tolerance), dielectric material (polypropylene metallized), mounting configuration (chassis mount with quick connect termination), and lead spacing (0.813"). The substitute part is physically compatible with existing mounting brackets and holders.

Q: What is the significance of the height difference between the two parts?

A: The 23FB44225A-F is 0.090" (2.29mm) shorter than the 23FB44225-F (3.160" versus 3.250" seated height). This reduction does not affect mounting compatibility or electrical performance. The smaller height may provide improved clearance in space-constrained applications. No circuit modifications are required.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant and carry identical MSL ratings (1 - Unlimited). The substitute part maintains all regulatory certifications of the original part.

Q: Why is the main part classified as obsolete?

A: The 23FB44225-F is listed as obsolete by the manufacturer. The 23FB44225A-F represents the active production equivalent within the same MPF series, ensuring continued availability for replacement and maintenance applications.

Q: What applications are these capacitors suitable for?

A: Both parts are rated for motor run and power factor correction (PFC) applications. The 440V AC rating and polypropylene dielectric construction make these components suitable for industrial motor circuits and power conditioning systems operating within the specified temperature range (-40°C to 70°C).

Q: Is the quick connect/disconnect termination compatible with standard motor run capacitor installations?

A: Yes. The quick connect/disconnect termination is a standard interface for motor run capacitors in industrial applications. Both parts utilize this termination style, ensuring compatibility with existing wiring harnesses and connection systems.
