Substitute Part Grouping Explanation

Substitution of the CAP-10/440 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CAP-10/440R maintains identical specifications in the following key areas:

• Capacitance Value: 10 µF (exact match)
• Voltage Rating: 440 V (exact match)
• Tolerance: ±3% (exact match)
• Lifetime Rating: 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-10/440R is classified as a direct equivalent substitute, not an upgrade, as it provides identical electrical performance and mechanical compatibility for motor run capacitor applications.

Parameter Comparison

Engineering Selection Recommendations

The CAP-10/440R serves as a direct equivalent substitute for the CAP-10/440. Both components are classified as discontinued at DiGi Electronics, indicating limited availability through standard distribution channels. Selection between these parts should be based on current inventory status and procurement lead times rather than technical differentiation.

Both parts carry identical ECCN classification (EAR99) and are subject to the same export control regulations. The CAP-10/440R is available in box packaging, whereas the main part number does not specify packaging format in the provided data.

For applications requiring 10 µF, 440 V motor run capacitors in HVAC systems with chassis mount configuration and QC terminals, either part number provides equivalent electrical and mechanical performance. Component selection should prioritize availability and delivery schedule.

Frequently Asked Questions (FAQ)

Q: Can CAP-10/440R be used as a direct replacement for CAP-10/440?

A: Yes. The CAP-10/440R is a direct equivalent substitute. All electrical parameters (capacitance, voltage rating, tolerance, lifetime rating, operating temperature range) and mechanical specifications (package type, terminal configuration, mounting type) are identical between the two part numbers.

Q: Are there differences in the QC terminal configuration between these parts?

A: No. Both the CAP-10/440 and CAP-10/440R feature identical radial, can-style QC terminals and chassis mount configuration. Physical and electrical compatibility is maintained.

Q: What is the significance of the "R" designation in CAP-10/440R?

A: The "R" designation indicates a packaging or distribution variant. The CAP-10/440R is specified with box packaging, while the main part number does not include packaging specification in the provided documentation. The electrical and mechanical specifications remain identical.

Q: Are both parts suitable for HVAC motor run applications?

A: Yes. Both CAP-10/440 and CAP-10/440R are classified for HVAC applications and belong to the HCK motor run series. They are rated for 60,000 hours at 70°C, meeting standard motor run capacitor performance requirements.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across the temperature range of -40°C to 70°C. The lifetime rating of 60,000 hours is specified at the 70°C reference temperature.

Q: Do these parts have any moisture sensitivity concerns?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.

Q: Why are both parts listed as discontinued?

A: Both the CAP-10/440 and CAP-10/440R are discontinued at DiGi Electronics. This status reflects distribution channel discontinuation rather than manufacturer discontinuation. Availability through alternative suppliers or direct manufacturer channels should be evaluated for procurement planning.
