TRADEPRO 50+7.5 MFD 370/440 VAC Round Dual Run Capacitor TP-CAP-50/7.5/440R-A

The TRADEPRO TP-CAP-50/7.5/440R is a high-quality dual run capacitor designed for reliable performance in residential and light commercial HVAC systems. It supplies the correct phase shift and capacitance to both the compressor (HERM) and condenser fan motor from a single compact unit, helping systems start and run efficiently.

Key Specifications

• Capacitance: 50 + 7.5 MFD (µF) dual run
• Voltage: 370/440 VAC (dual-rated; 440V can safely replace 370V applications)
• Frequency: 50/60 Hz
• Shape: Round
• Tolerance: ±3% (industry-best, tested to EIA-456-A)
• Operating Temperature: –40°C to 70°C (–40°F to 158°F)
• Expected Life: 60,000 hours at rated temperature
• Protection: 10,000 AFC protected
• Approvals: UL/CSA recognized, VDE approved; meets EIA-456-A and UL 810 standards
• Construction: Rigid aluminum can, vacuum-sealed, thick 7-micrometer Mylar film, 1.5 mm plastic cup support, Nomex sleeve for insulation and protection

Approximate Dimensions (sources vary slightly by listing):

• Diameter: ≈ 2.09–2.46 in (≈ 2-1/16 to 2-7/16 in)
• Height/Length: ≈ 4.41–4.92 in (≈ 4-7/16 to 4.92 in)
• Weight: ≈ 0.5–1.2 lbs

Features

• Dual-rated for both 370V and 440V systems in one capacitor
• Thick 7 µm film, plastic cup, and Nomex sleeve for greater reliability versus thinner-film competitors
• Vacuum-sealed construction helps eliminate leaks and contaminants
• Multi-tab quick-connect terminals for flexible wiring
• Aluminum housing for durability and heat dissipation
• Extensive electrical testing before shipment

Benefits

• Restores proper starting torque and running efficiency for compressor and fan motors
• Reduces the chance of motor failure, hard starting, humming, or short-cycling caused by a weak or failed capacitor
• Long service life and robust construction lower callback rates and replacement frequency
• Single dual capacitor simplifies installation and saves space compared with two separate capacitors
• OEM-quality performance at a competitive price point for professional and DIY replacements

Compatibility

This is a universal dual-run replacement for systems requiring 50 MFD (compressor/HERM) + 7.5 MFD (fan) at 370 or 440 VAC. It is commonly used in central air conditioners, heat pumps, and condenser units from major brands (Carrier, Trane, Rheem, Goodman, American Standard, and others) when the capacitance, voltage, and physical size match the original.

Common cross-references / equivalents include: C45075R, 97F9987, USA2238, P291-5073RS / P291-5074RS, CAP-50/7.5/440R, HCKS500D075R440Z, and similar 50/7.5 MFD 370/440V round dual capacitors.

Important notes:

• Always match the exact MFD ratings (50 + 7.5). Voltage can go up (440V replaces 370V) but never down.
• Confirm physical dimensions and terminal orientation fit your unit. Round and oval cases of matching electrical ratings are electrically interchangeable; mounting may differ.
• Capacitors store a dangerous charge even when power is off—discharge properly before handling and follow all safety procedures.

Ideal for HVAC technicians and homeowners looking for a dependable, tested dual run capacitor that delivers consistent performance in demanding outdoor environments.
