Substitute Part Grouping Explanation

Substitution of the HC2-2R2-R is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 2.2 µH
• Inductance tolerance: ±20%
• Current rating: 24.3 A minimum
• Saturation current (Isat): 31.9 A minimum
• DC resistance: 2.3 mOhm maximum
• Operating temperature range: -40°C to 85°C minimum
• Test frequency: 300 kHz

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Shielding configuration: Unshielded
• Package classification: Nonstandard
• Physical dimensions compatible with PCB layout constraints

The HC2LP-2R2-R qualifies as a direct substitute based on matching all electrical parameters and maintaining surface mount compatibility. The substitute part operates within identical current and temperature specifications while maintaining the same inductance value and tolerance band.

Engineering Selection Recommendations

Primary Substitute: HC2LP-2R2-R

The HC2LP-2R2-R is the qualified direct substitute for the obsolete HC2-2R2-R. Selection of this component is based on the following engineering factors:

Product Status Alignment: The HC2LP-2R2-R maintains active product status with Eaton - Electronics Division, ensuring continued availability and manufacturing support. The obsolete HC2-2R2-R requires replacement to maintain supply chain continuity.

Electrical Parameter Equivalence: All critical electrical specifications match exactly: 2.2 µH inductance at ±20% tolerance, 24.3 A current rating, 31.9 A saturation current, and 2.3 mOhm maximum DC resistance. Operating temperature range and test frequency are identical.

Compliance and Certification: Both components maintain RoHS compliance. The HC2LP-2R2-R achieves ROHS3 compliance, representing current regulatory alignment. The substitute carries REACH Unaffected status, confirming regulatory compatibility.

Mechanical Compatibility: Surface mount configuration and nonstandard package classification remain consistent. The HC2LP-2R2-R exhibits a lower seated height (0.440" versus 0.500"), which provides design flexibility for space-constrained applications without compromising electrical performance.

Core Material Specification: The HC2LP-2R2-R specifies ferrite drum core construction, providing defined core material characteristics that support consistent inductance performance across the operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the HC2LP-2R2-R be used as a direct replacement for the HC2-2R2-R in existing designs?

A: Yes. The HC2LP-2R2-R qualifies as a direct substitute. All electrical parameters—inductance value, current rating, saturation current, and DC resistance—are identical. Both components operate across the same temperature range and are surface mount devices with unshielded configuration. The substitute maintains functional equivalence for circuit operation.

Q: What is the difference between the HC2 and HC2LP series?

A: The HC2LP series represents an active product line evolution from the obsolete HC2 series. The HC2LP-2R2-R incorporates ferrite drum core construction and maintains all electrical specifications of the original HC2-2R2-R. The primary distinction is product status: HC2LP is active, while HC2 is obsolete.

Q: Are there physical dimension differences that affect PCB layout?

A: Minor dimensional variations exist. The HC2LP-2R2-R has a width of 0.756" (19.20mm) compared to 0.748" (19.00mm) for the HC2-2R2-R, representing a 0.008" difference. The seated height of the substitute is 0.440" (11.18mm) versus 0.500" (12.70mm), making it lower profile. These differences are within typical PCB design tolerances for surface mount components and do not prevent substitution.

Q: Does the ferrite core material in the HC2LP-2R2-R affect circuit performance?

A: The ferrite core material in the HC2LP-2R2-R is specified to deliver the same inductance value (2.2 µH) and tolerance (±20%) as the original HC2-2R2-R across the 300 kHz test frequency. Core material selection is engineered to maintain electrical equivalence within the operating temperature range of -40°C to 85°C.

Q: What is the inventory status for these components?

A: The HC2-2R2-R (obsolete) has 913 pieces in stock. The HC2LP-2R2-R (active substitute) has 1,740 pieces available. The substitute offers superior supply chain availability due to its active product status.

Q: Are both components RoHS compliant?

A: Yes. The HC2-2R2-R is RoHS Compliant. The HC2LP-2R2-R achieves ROHS3 Compliant status, representing current regulatory requirements. Both components meet environmental compliance standards for electronic component manufacturing.

Q: What packaging options are available for the HC2LP-2R2-R?

A: The HC2LP-2R2-R is supplied in Cut Tape (CT) packaging. This standard surface mount packaging format is compatible with automated assembly processes and component handling systems.
