Substitute Part Grouping Explanation

Substitution of the CAP-30/440 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CAP-30/440R maintains identical specifications in the following key areas:

• Capacitance Value: 30 µF (exact match)
• Voltage Rating: 440 V (exact match)
• Tolerance: ±3% (exact match)
• Thermal Lifetime: 60,000 Hrs @ 70°C (exact match)
• Operating Temperature Range: -40°C ~ 70°C (exact match)
• Polarization: Polar (exact match)
• Package Configuration: Radial, Can - QC Terminals (exact match)
• Mounting Type: Chassis Mount (exact match)
• Series Classification: HCK, Motor Run (exact match)
• Application Category: HVAC (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)

The CAP-30/440R is an active product from the same manufacturer (Hartland Controls/Littelfuse) and serves as a direct replacement for the discontinued CAP-30/440.

Parameter Comparison

Engineering Selection Recommendations

The CAP-30/440R is the appropriate substitute for the discontinued CAP-30/440 based on the following engineering criteria:

Product Status: The CAP-30/440R maintains active product status from the original manufacturer, ensuring continued availability and supply chain reliability. The original CAP-30/440 is discontinued, making the CAP-30/440R the current equivalent offering.

Electrical Equivalence: All electrical parameters are identical between the main part and substitute, including capacitance value, voltage rating, tolerance, and thermal lifetime specifications. This ensures functional compatibility in motor run HVAC applications without circuit redesign or performance degradation.

Mechanical Compatibility: The package configuration, terminal type (QC Terminals), and mounting method (Chassis Mount) are identical, enabling direct physical replacement without PCB or assembly modifications.

Compliance and Certifications: Both parts share identical ECCN (EAR99) and HTSUS classifications, maintaining regulatory compliance for the same applications and markets.

Inventory Availability: The CAP-30/440R is available in production quantities (825 Pcs in stock), supporting both new designs and replacement requirements.

Frequently Asked Questions (FAQ)

Q: Can the CAP-30/440R be used as a direct replacement for the CAP-30/440?

A: Yes. The CAP-30/440R is a direct substitute with identical electrical specifications (30 µF, 440 V, ±3% tolerance), thermal ratings (60,000 Hrs @ 70°C), operating temperature range (-40°C ~ 70°C), and mechanical package (Radial, Can - QC Terminals). No circuit modifications or board-level changes are required.

Q: What is the difference between CAP-30/440 and CAP-30/440R?

A: The primary difference is product status. The CAP-30/440 is discontinued, while the CAP-30/440R is an active product from the same manufacturer. All electrical and mechanical specifications are identical. The packaging format differs slightly (original uses standard packaging; the R variant uses Box packaging), but this does not affect component performance or compatibility.

Q: Are the QC terminals on both parts identical?

A: Yes. Both the CAP-30/440 and CAP-30/440R use identical Radial, Can - QC Terminal configurations, ensuring mechanical and electrical compatibility with existing terminal connections and assembly processes.

Q: Can these capacitors be used in applications other than HVAC?

A: The specifications provided indicate these components are rated for HVAC applications. Use in other applications requires verification that the electrical and thermal specifications meet the requirements of the intended application.

Q: What does the ±3% tolerance mean for these capacitors?

A: The ±3% tolerance indicates that the actual capacitance value will be within 3% of the nominal 30 µF rating. This means the capacitance will fall between 29.1 µF and 30.9 µF. This tolerance is identical for both the main part and substitute.

Q: Are there any differences in the regulatory classifications between these parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8532.22.00xx) classifications, indicating equivalent regulatory treatment for export control and tariff purposes. Minor variations in the HTSUS code reflect standard administrative differences and do not affect component functionality or compliance.
