Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24FD3750-F is determined by matching the following critical electrical and mechanical parameters: 50 µF capacitance, ±10% tolerance, 370V AC voltage rating, polypropylene (PP) metallized dielectric, radial can package configuration, and 0.813" (20.64mm) lead spacing. These parameters ensure functional equivalence in motor run and power factor correction applications. The 24FD3750A-F meets all substitution criteria while offering the advantage of active product status and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The 24FD3750A-F is the direct equivalent and recommended substitute for the obsolete 24FD3750-F. Both parts share identical electrical specifications, mechanical dimensions (with a minor 0.090" height reduction), and mounting characteristics. The 24FD3750A-F maintains active product status within the MPF series, ensuring long-term availability. Both components satisfy ROHS3 compliance requirements and carry identical regulatory classification (EAR99, HTSUS 8532.25.0020). The primary distinction between these parts is packaging configuration and availability, with the substitute offered in bulk packaging and current inventory status.

Frequently Asked Questions (FAQ)

Q: Can the 24FD3750A-F physically replace the 24FD3750-F in existing equipment?

A: The 24FD3750A-F shares the identical diameter (2.625" / 66.68mm), lead spacing (0.813" / 20.64mm), and mounting type. The seated height differs by 0.090" (3.250" versus 3.160"), which is within typical mechanical tolerance for chassis-mounted, holder-bracketed installations. Physical fit compatibility should be confirmed for space-constrained applications.

Q: Are the electrical characteristics identical between these two parts?

A: Both the 24FD3750-F and 24FD3750A-F specify 50 µF capacitance with ±10% tolerance, 370V AC rating, polypropylene (PP) metallized dielectric, and -40°C to 70°C operating temperature range. They are electrically equivalent for motor run and power factor correction applications.

Q: What is the difference between the two packaging options?

A: The original 24FD3750-F is specified with standard packaging, while the 24FD3750A-F is available in bulk packaging. Bulk packaging typically reduces per-unit cost for higher-volume procurement but may impose minimum order quantities.

Q: How does the active status of the 24FD3750A-F benefit procurement?

A: Parts with active product status receive continued manufacturer support, consistent supply availability, and documented long-term manufacturability. The 24FD3750-F, listed as obsolete, faces increasing scarcity and potential future discontinuation of manufacturing.

Q: What regulatory certifications apply to both parts?

A: Both parts are ROHS3 compliant and classified under ECCN EAR99 with HTSUS code 8532.25.0020. Both carry MSL rating of 1 (Unlimited moisture sensitivity), indicating no special moisture protection requirements.
