HC2-2R2TR-R Equivalent & Substitute Parts

Part Overview

The HC2-2R2TR-R is a 2.2 µH unshielded wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 24.3 A continuous current with a maximum DC resistance of 2.3 mOhm and operates across the temperature range of -40°C to 85°C. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement continuity. The HC2 series represents a nonstandard package form factor in the wirewound inductor category, requiring careful parameter matching for replacement applications.

Substitute Part Grouping Explanation

Substitution of the HC2-2R2TR-R is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 2.2 µH at 300 kHz test frequency
• 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

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Shielding configuration: Unshielded
• Winding type: Wirewound construction
• Package form factor: Nonstandard

The HC2LP-2R2-R qualifies as a direct substitute based on matching all electrical parameters and maintaining compatible mechanical specifications. The substitute part differs in core material composition (ferrite drum core versus standard wirewound) and minor dimensional variations, which do not affect functional performance within the specified parameter envelope.

Engineering Selection Recommendations

The HC2LP-2R2-R is the qualified substitute for the obsolete HC2-2R2TR-R based on the following engineering criteria:

Electrical Performance: All critical electrical parameters match exactly, including inductance value, current ratings, saturation characteristics, and DC resistance specifications. Both parts operate identically within the specified 300 kHz test frequency and -40°C to 85°C temperature range.

Product Status and Availability: The HC2LP-2R2-R maintains active product status with documented inventory availability (1740 pcs), whereas the HC2-2R2TR-R is classified as obsolete. This transition ensures long-term supply chain continuity and design support.

Compliance and Certifications: The HC2LP-2R2-R meets ROHS3 compliance requirements and maintains the same MSL rating (1 - Unlimited) as the original part. Both components carry identical ECCN and HTSUS classifications, confirming regulatory equivalence.

Mechanical Compatibility: Dimensional variations are minimal and within acceptable tolerances for surface mount applications. The substitute part features a slightly reduced height (0.440" versus 0.500"), which presents no functional constraint for standard PCB layouts. The width difference of 0.008" (0.20 mm) is negligible for component placement and routing.

Core Material Consideration: The HC2LP-2R2-R employs a ferrite drum core construction versus the standard wirewound design of the original part. This construction method maintains all specified electrical performance while providing enhanced reliability and consistency in the active product line.

Frequently Asked Questions (FAQ)

Q: Can the HC2LP-2R2-R be used as a direct replacement for the HC2-2R2TR-R in existing designs?

A: Yes. The HC2LP-2R2-R is a direct electrical and mechanical substitute. All critical parameters—inductance, current rating, saturation current, DC resistance, and operating temperature range—are identical. The substitute part is fully compatible with existing PCB layouts and circuit designs.

Q: What is the difference between the HC2-2R2TR-R and HC2LP-2R2-R?

A: The primary differences are product status and core construction. The HC2-2R2TR-R is obsolete, while the HC2LP-2R2-R is an active product. The HC2LP-2R2-R uses a ferrite drum core wirewound construction, whereas the original uses standard wirewound construction. Electrically and functionally, both parts are equivalent.

Q: Are there any dimensional constraints when substituting the HC2LP-2R2-R?

A: The HC2LP-2R2-R is slightly smaller in height (0.440" versus 0.500") and marginally wider (0.756" versus 0.748"). These differences are within standard PCB layout tolerances and present no practical constraint for component placement or routing.

Q: Does the HC2LP-2R2-R meet the same compliance requirements?

A: Yes. The HC2LP-2R2-R meets ROHS3 compliance and maintains the same MSL rating (1 - Unlimited) as the original part. Both components carry identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications.

Q: What is the packaging format for the HC2LP-2R2-R?

A: The HC2LP-2R2-R is supplied in Cut Tape (CT) packaging, suitable for automated assembly processes and component handling.

Q: Is the HC2LP-2R2-R available in stock?

A: Yes. The HC2LP-2R2-R has documented inventory availability of 1740 pcs as new original stock, ensuring reliable procurement for production requirements.

Q: Will the ferrite drum core construction affect circuit performance?

A: No. The ferrite drum core construction in the HC2LP-2R2-R maintains all specified electrical characteristics at the 300 kHz test frequency. The inductance value, tolerance, current handling, and DC resistance are identical to the original part, ensuring equivalent circuit performance.
