HC2-4R7-R Equivalent & Substitute Parts

Part Overview

The HC2-4R7-R is a 4.7 µH unshielded wirewound inductor manufactured by Eaton - Electronics Division, rated for 17 A continuous current with a maximum DC resistance of 4.6 mOhm. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. The HC2-4R7-R operates across the temperature range of -40°C to 85°C and is RoHS compliant. Due to its obsolete status, sourcing active alternatives with identical electrical and mechanical specifications is necessary to maintain supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the HC2-4R7-R is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 4.7 µH
• Inductance tolerance: ±20%
• Current rating: 17 A minimum
• Saturation current (Isat): 21.25 A
• DC resistance: 4.6 mOhm maximum
• Operating temperature range: -40°C to 85°C minimum
• Inductance test frequency: 300 kHz

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Shielding configuration: Unshielded
• Package classification: Nonstandard

The HC2LP-4R7-R qualifies as a direct substitute based on matching all electrical parameters and maintaining surface mount compatibility. The substitute part transitions from obsolete to active product status while preserving functional equivalence.
