Trane SFCAP45D75440R Capacitor
The Trane SFCAP45D75440R Capacitor is a high-performance dual run capacitor designed for demanding HVACR applications. As a veteran-grade OEM replacement part, this 45/7.5 MFD 370/440V component provides the precise phase shift required for simultaneous operation of the compressor and condenser fan motor. Built with metallized polypropylene film technology and housed in a rugged round run capacitor aluminum casing, it maintains stable capacitance across a broad temperature range from -40°C to 70°C. This dual capacitance unit is rated for 370/440 VAC, allowing technicians to use it as a universal fit for either voltage rating, effectively consolidating truck stock. Featuring standard 1/4-inch quick-connect terminals, it ensures a secure, low-resistance connection essential for preventing localized overheating and premature failure. This Trane capacitor is the direct superseding HVAC replacement part for model CPT00669, ensuring seamless integration with Trane, American Standard, and ServiceFirst units.
Key Benefits
- Dual-Action Performance: Simultaneously regulates the 45 MFD compressor circuit and the 7.5 MFD fan motor circuit for synchronized system operation.
- Voltage Versatility: The 370/440V AC rating provides 440V protection while remaining fully compatible with 370V systems.
- OEM Reliability: Engineered to original Trane factory specifications to maintain the intended Power Factor and efficiency of the equipment.
- Enhanced Durability: Non-PCB oil-filled construction provides superior heat dissipation and internal pressure-sensitive interrupter safety.
- Universal Round Profile: Standardized dimensions allow for easy mounting in existing capacitor straps and brackets.
Common Questions
Can I use a 440V capacitor if my old one was 370V?
Yes. Capacitors are rated for maximum voltage. Using a 440V capacitor in a 370V application is a standard industry practice that provides a higher breakdown voltage margin, often resulting in increased component longevity.
What are the signs of a failing 45/7.5 MFD capacitor?
Technicians should look for physical bulging (domed top), oil leaks, or "short cycling" where the compressor hums but fails to roll over. Always verify with a multimeter to ensure microfarad readings stay within the ±5% tolerance range.
Is the SFCAP45D75440R compatible with American Standard units?
Yes, because Trane and American Standard share the same manufacturing platform, this OEM part is the correct technical replacement for corresponding microfarad and voltage requirements in those systems.
