TRADEPRO 30+5 MFD 370/440 VAC Round Dual Run Capacitor TP-CAP-30/5/440R-A

Professional-grade dual-run motor capacitor designed for residential air conditioning condensers, heat pumps, and similar HVAC systems. It supplies the precise phase shift needed for both the compressor (HERM) and outdoor fan motor, restoring efficient starting and running performance. Commonly used as a high-quality replacement in Frigidaire and other major-brand outdoor units.

Dimensions

• Overall length/height: approximately 3.82–4 inches
• Diameter: 2.07 inches (round aluminum case)
• Weight: ~0.5 lbs (shipping weight often listed ~0.5–0.8 lbs)

Compact round form factor fits standard HVAC mounting brackets and enclosures.

Features

• Dual capacitance: 30 MFD (compressor/HERM) + 5 MFD (fan)
• Dual voltage rating: 370/440 VAC (higher-voltage design provides extra headroom)
• Round aluminum oil-filled case for heat dissipation and durability
• Frequency: 50/60 Hz
• Multi-spade/quick-connect terminals (typically labeled C/Common, HERM, FAN)
• Built-in pressure-sensitive interrupter (safety disconnect on failure)
• Meets EIA-456-A standards; UL/CSA recognized; protected to 10,000 AFC
• Operating temperature range: –40°F to 158°F (–40°C to 70°C)
• Rated operating life: up to 60,000 hours
• Non-PCB oil and robust internal construction (metallized film)

Benefits

• Restores proper compressor and fan motor operation when the original capacitor has weakened or failed (common cause of no-cool, hard-starting, or humming issues)
• 440 VAC rating improves reliability and surge tolerance compared with many older 370 V units
• Long service life and quality construction reduce callbacks and repeat failures
• Direct, easy drop-in replacement with standard terminal layout
• Helps maintain system efficiency and protects motors from damage due to improper capacitance
• OEM-quality performance at a competitive price point for contractors and DIY-capable homeowners

Specifications

Compatibility

Direct replacement for systems requiring a 30/5 MFD (30+5 µF) dual-run round capacitor rated 370 V or 440 V. Widely used in residential central air conditioners, heat pumps, and packaged units.

Cross-references/replaces many equivalent part numbers, including (but not limited to): TP-CAP-30/5/440R, 97F9981 / 97F9981BX, C4305R / C3305R, CPT00659 / CPT-0659, 27L20 / 27L877 series, CD30+5X370R / CD30+5X440R, USA2226, and numerous other 30/5 MFD 370–440 V round dual-run capacitors.

Compatible with Frigidaire outdoor units and many Carrier, Goodman, Amana, Payne, and similar brands that specify this capacitance and voltage. Always verify the exact MFD values, voltage, shape (round), and physical fit against the original capacitor label or unit documentation before installation. Not a universal fit for every model—match specifications precisely.

Note: Capacitor replacement involves high voltage and should be performed by a qualified technician following proper safety procedures (discharge the old capacitor, lockout/tagout, match polarity/terminals correctly). Confirm exact specifications on the failed unit before ordering.
