HC2-R68-R Equivalent & Substitute Parts

Part Overview

The HC2-R68-R is a 680 nH unshielded wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 52.9 A continuous current with a maximum DC resistance of 0.6 mOhm and operates across the temperature range of -40°C to 85°C. The part carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC2-R68-R is determined by strict equivalence across the following critical parameters:

Inductance Value: 680 nH with ±20% tolerance is the primary electrical specification. Substitute parts must maintain this exact inductance value and tolerance band.

Current Ratings: Both continuous current rating (52.9 A) and saturation current (50 A) must be matched or exceeded. These parameters define the component's thermal and magnetic performance limits.

DC Resistance: Maximum DCR of 0.6 mOhm establishes the resistive loss characteristic. Substitute parts must not exceed this specification.

Shielding Configuration: Unshielded topology must be preserved to maintain electromagnetic coupling characteristics in the circuit design.

Operating Temperature Range: The -40°C to 85°C specification must be supported by the substitute part.

Mounting and Package: Surface mount configuration with nonstandard package dimensions (19.20mm × 19.00mm × 12.70mm max height) defines the physical footprint compatibility.

Compliance Standards: RoHS compliance and MSL 1 rating must be maintained.

The HC2LP-R68-R qualifies as a direct substitute based on matching all critical electrical parameters, operating temperature range, compliance certifications, and surface mount configuration.

Engineering Selection Recommendations

The HC2LP-R68-R is the qualified substitute for the obsolete HC2-R68-R based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters—inductance value, tolerance, current ratings, and DC resistance—are identical between the main part and substitute. This ensures functional interchangeability in the circuit application.

Product Status Transition: The HC2-R68-R is obsolete, while the HC2LP-R68-R maintains active product status with Eaton - Electronics Division. This transition ensures long-term availability and supply chain continuity.

Compliance Alignment: Both parts maintain RoHS compliance and MSL 1 rating, satisfying regulatory and environmental requirements without modification to the design or procurement process.

Physical Compatibility: The substitute part features a slightly reduced height (11.18 mm versus 12.70 mm maximum), which provides improved board-level clearance. The length dimension is identical (19.20 mm), and the width difference of 0.20 mm is within typical PCB layout tolerances for surface mount components.

Core Technology: The HC2LP-R68-R specifies ferrite drum core construction, providing defined magnetic characteristics that support the specified inductance and current ratings.

Frequently Asked Questions (FAQ)

Q: Can the HC2LP-R68-R be used as a direct replacement for the HC2-R68-R in existing designs?

A: Yes. The HC2LP-R68-R is electrically and functionally equivalent to the HC2-R68-R across all critical parameters: inductance value, tolerance, current ratings, DC resistance, operating temperature range, and shielding configuration. The substitute part is suitable for direct PCB layout substitution.

Q: What is the significance of the core material difference between the two parts?

A: The HC2-R68-R does not specify core material in the provided data, while the HC2LP-R68-R identifies ferrite drum core construction. Ferrite core material is standard for wirewound inductors in this inductance and current rating class and supports the specified electrical performance.

Q: Are there physical footprint considerations when substituting the HC2LP-R68-R?

A: The substitute part is 1.52 mm shorter in height (11.18 mm versus 12.70 mm maximum), which improves clearance on the PCB. The length dimension is identical at 19.20 mm. The width increases by 0.20 mm (from 19.00 mm to 19.20 mm), which is within standard PCB layout tolerances for surface mount components and does not require design modification.

Q: Does the HC2LP-R68-R maintain the same packaging format?

A: The HC2LP-R68-R is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount production. The main part packaging format was not specified in the provided data. Tape & Reel packaging is compatible with automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the HC2-R68-R and HC2LP-R68-R are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting regulatory requirements for electronic component procurement.

Q: Why is the HC2-R68-R listed as obsolete?

A: The HC2-R68-R carries obsolete product status, indicating that Eaton - Electronics Division has discontinued active production and support. The HC2LP-R68-R, as an active product with identical electrical specifications, is the recommended path for ongoing procurement and design support.
