Engineering Selection Recommendations

The 24FB4430A-F is a direct substitute for the obsolete 24FB4430-F based on the following engineering criteria:

Electrical Equivalence: Both parts share identical electrical specifications: 30 µF capacitance, ±10% tolerance, 440V AC rating, and polypropylene metallized dielectric construction. These parameters ensure functional interchangeability in motor run and power factor correction circuits.

Mechanical Compatibility: Both parts feature identical radial can packaging, chassis mount configuration, quick connect/disconnect termination, and lead spacing of 0.813" (20.64mm). The height difference of 0.090" (2.29mm) between the main part (3.250") and substitute (3.160") remains within acceptable mounting tolerances for standard holder/bracket assemblies.

Compliance Status: The 24FB4430A-F maintains ROHS3 compliance and MSL rating 1 (Unlimited) identical to the main part. The substitute carries active product status, ensuring continued availability and supply chain support.

Series Continuity: Both components belong to the Cornell Dubilier Electronics MPF series, confirming manufacturer design lineage and performance consistency.

Frequently Asked Questions (FAQ)

Q: Can the 24FB4430A-F replace the 24FB4430-F in existing applications?

A: Yes. The 24FB4430A-F is a direct electrical and mechanical substitute. Identical capacitance, voltage rating, tolerance, dielectric material, package type, termination style, and lead spacing ensure drop-in compatibility in motor run and power factor correction circuits.

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

A: The 24FB4430-F has a seated height of 3.250" (82.55mm), while the 24FB4430A-F measures 3.160" (80.26mm). This 0.090" (2.29mm) reduction falls within standard mounting tolerances for radial can capacitor holder/bracket assemblies and does not affect functional performance or mechanical fit.

Q: Why is the 24FB4430-F listed as obsolete?

A: The 24FB4430-F carries obsolete product status. The 24FB4430A-F represents the active continuation of this specification within the Cornell Dubilier Electronics MPF series.
