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

The substitute part CAP-25/440 meets all electrical and mechanical parameter requirements for direct substitution with the CAP-25/440R. Both parts are manufactured by Hartland Controls/Littelfuse and maintain identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CAP-25/440R and CAP-25/440 are Active products manufactured by Hartland Controls/Littelfuse with identical electrical specifications and mechanical configurations. Selection between these parts is based on inventory availability and supply chain considerations rather than technical performance differences.

The CAP-25/440R maintains 820 units in current stock inventory. The CAP-25/440 substitute maintains 748 units in current stock inventory. Both parts carry identical ECCN classification (EAR99) and comply with the same regulatory framework (HTSUS codes 8532.22.0055 and 8532.22.0085 respectively).

For HVAC motor run applications requiring 25 µF capacitance at 440 V operation, either part number provides equivalent performance and reliability characteristics. Component selection should be determined by procurement lead times, inventory position, and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can CAP-25/440 be used as a direct replacement for CAP-25/440R?

A: Yes. The CAP-25/440 is a direct electrical and mechanical equivalent to the CAP-25/440R. Both parts share identical capacitance (25 µF), voltage rating (440 V), tolerance (±3%), lifetime rating (60,000 Hrs @ 70°C), operating temperature range (-40°C ~ 70°C), package configuration (Radial, Can - QC Terminals), and mounting type (Chassis Mount).

Q: Are there any differences in the physical dimensions or terminal configuration?

A: No dimensional or terminal configuration differences exist between these parts. Both utilize QC (Quick Connect) terminals in a radial, can-style package suitable for chassis mount applications.

Q: What is the significance of the part number suffix difference between CAP-25/440R and CAP-25/440?

A: The part numbers differ only in the final character designation. This distinction does not reflect differences in electrical performance, mechanical compatibility, or functional capability. Both parts are manufactured by Hartland Controls/Littelfuse within the HCK Motor Run series.

Q: Are both parts suitable for HVAC applications?

A: Yes. Both CAP-25/440R and CAP-25/440 are specified for HVAC applications and maintain identical performance ratings for motor run capacitor duty.

Q: What is the moisture sensitivity classification for these parts?

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

Q: Can these capacitors be used interchangeably in existing circuit designs?

A: Yes. The electrical parameters (capacitance, voltage rating, tolerance, temperature characteristics) and mechanical parameters (package type, terminal configuration, mounting method) are identical, permitting direct interchangeability in circuit applications.
