CAP-5/440 Equivalent & Substitute Parts

Part Overview

The CAP-5/440 is a 5 µF, 440 V aluminum electrolytic capacitor with radial, can-style QC terminals designed for motor run applications in HVAC systems. This component is rated for 60,000 hours at 70°C operating temperature with ±3% capacitance tolerance. The part is currently discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for direct replacement in existing designs and applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAP-5/440 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical capacitance value (5 µF), rated voltage (440 V), tolerance specification (±3%), thermal lifetime rating (60,000 Hrs @ 70°C), operating temperature range (-40°C ~ 70°C), polarization type (Polar), package configuration (Radial, Can - QC Terminals), and mounting methodology (Chassis Mount). The substitute must also be qualified for the same application category (HVAC motor run) and maintain the same series designation (HCK, Motor Run). All parameters listed in the Key Parameters table must match exactly for direct substitution without circuit redesign or validation testing.

Engineering Selection Recommendations

The CAP-5/440R is the direct equivalent substitute for the discontinued CAP-5/440. Both parts are manufactured by Hartland Controls/Littelfuse and share identical electrical specifications, thermal ratings, and mechanical packaging. The primary distinction is product status: CAP-5/440 is discontinued while CAP-5/440R maintains active production status. The CAP-5/440R additionally carries RoHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs and procurement cycles. For applications currently utilizing CAP-5/440, direct substitution with CAP-5/440R requires no circuit modifications, board layout changes, or performance re-evaluation, as all specified parameters remain equivalent.
