Key Parameters

Substitute Part Grouping Explanation

Substitution of the 24FD3780-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance: 80 µF
• Tolerance: ±10%
• Voltage Rating (AC): 370V
• Dielectric Material: Polypropylene (PP), Metallized

Mechanical Parameters (Non-Negotiable):

• Package Type: Radial, Can
• Termination: Quick Connect, Disconnect
• Lead Spacing: 0.813" (20.64mm)
• Operating Temperature Range: -40°C to 70°C

Compliance Parameters:

• RoHS3 Compliance
• Moisture Sensitivity Level (MSL): 1

The substitute part 24FD3780A-F maintains identical electrical and mechanical specifications while offering active product status and improved availability. Physical dimension variations (can diameter) do not affect functional equivalence when the mounting bracket accommodates the specified lead spacing and termination type.

Parameter Comparison

Engineering Selection Recommendations

The 24FD3780A-F is a direct functional equivalent to the 24FD3780-F for all motor run and power factor correction applications. Selection between these parts is based on availability and product lifecycle status:

Use 24FD3780A-F when:

• New component procurement is required
• Long-term supply chain continuity is necessary
• Active product support and documentation are required

Use 24FD3780-F when:

• Existing inventory stock is available and acceptable
• Exact physical form factor matching is critical
• Cost optimization favors obsolete stock utilization

Both parts maintain identical electrical performance, thermal operating range, and regulatory compliance (RoHS3, MSL 1). The can diameter increase in the 24FD3780A-F (2.625" versus 2.500") requires verification that the mounting bracket or holder accommodates the larger diameter while maintaining the identical 0.813" lead spacing and 5.000" seated height.

Frequently Asked Questions (FAQ)

Q: Can the 24FD3780A-F replace the 24FD3780-F in existing equipment?

A: Yes. Both parts are electrically and mechanically equivalent with identical capacitance (80 µF), voltage rating (370V AC), tolerance (±10%), dielectric material (polypropylene metallized), termination type (quick connect), and lead spacing (0.813"). The physical can diameter differs slightly (2.625" versus 2.500"), requiring confirmation that the mounting bracket accommodates this dimension.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 24FD3780A-F is an active product with ongoing manufacturer support, documentation, and supply availability. The 24FD3780-F is obsolete and no longer manufactured. For new designs or long-term maintenance programs, the active substitute ensures continued component availability and technical support.

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

A: No. Both parts are RoHS3 compliant, carry MSL rating 1 (unlimited moisture sensitivity), and share identical ECCN (EAR99) and HTSUS (8532.25.0020) classifications.

Q: Does the can diameter increase affect electrical performance?

A: No. The can diameter is a mechanical packaging feature. Electrical performance, capacitance, voltage rating, and thermal characteristics remain identical. The diameter increase does not affect circuit operation provided the mounting bracket accommodates the larger dimension.

Q: What applications are these capacitors suitable for?

A: Both parts are rated for motor run and power factor correction (PFC) applications, operating across the -40°C to 70°C temperature range with 370V AC voltage rating.

Q: How should I verify compatibility in my specific application?

A: Confirm that your mounting bracket or holder accepts the 0.813" lead spacing, quick connect termination type, and the can diameter of the substitute part (2.625" with lip for the 24FD3780A-F). Verify that the 80 µF capacitance and 370V AC rating match your circuit requirements.
