Substitute Part Grouping Explanation

Substitution of the HC2-R68TR-R is determined by strict equivalence across the following critical parameters:

  • Inductance Value: 680 nH with ±20% tolerance
  • Current Rating: 52.9 A continuous current capability
  • Saturation Current: 50 A minimum
  • DC Resistance: 0.6 mOhm maximum
  • Shielding Configuration: Unshielded topology
  • Operating Temperature: -40°C to 85°C range
  • Mounting: Surface mount configuration
  • Compliance: RoHS compliant status

The HC2LP-R68-R qualifies as a direct substitute based on matching all electrical specifications and environmental ratings. While the substitute employs a drum core ferrite construction compared to the original wirewound design, both components deliver identical electrical performance within the specified parameters.

Engineering Selection Recommendations

The HC2LP-R68-R is the qualified substitute for the obsolete HC2-R68TR-R based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters—inductance value, current rating, saturation current, and DC resistance—are identical between the main part and substitute. Both components operate within the same temperature range and maintain RoHS compliance.

Product Status Advantage: The HC2LP-R68-R carries an active product status with 2797 units in stock, compared to the obsolete HC2-R68TR-R. This ensures long-term availability and supply chain continuity for new designs and production runs.

Compliance Certification: Both parts maintain RoHS compliant status and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Physical Compatibility: The substitute exhibits minimal dimensional variation. The width increases by 0.008" (0.20mm) while the seated height decreases by 0.060" (1.52mm). These variations fall within typical PCB layout tolerances for surface mount applications.

Construction Difference: The HC2LP-R68-R employs a drum core ferrite construction versus the original wirewound design. This architectural difference does not affect electrical performance within the specified parameters and represents a manufacturing evolution within the HC2 series.

Frequently Asked Questions (FAQ)

Q: Can the HC2LP-R68-R be used as a direct replacement for the HC2-R68TR-R in existing designs?

A: Yes. The HC2LP-R68-R meets all electrical specifications of the HC2-R68TR-R, including inductance value, current rating, saturation current, and DC resistance. Both components operate across -40°C to 85°C and maintain RoHS compliance. The substitute is suitable for direct substitution in circuit applications.

Q: What is the significance of the product status change from Obsolete to Active?

A: The HC2LP-R68-R active status indicates ongoing manufacturing and availability. This eliminates supply risk associated with the obsolete HC2-R68TR-R and ensures procurement reliability for current and future production requirements.

Q: How do the physical dimensions affect PCB layout compatibility?

A: The HC2LP-R68-R is 0.008" wider and 0.060" shorter than the HC2-R68TR-R. These variations are within standard surface mount component tolerances. PCB layouts designed for the original part will accommodate the substitute without modification in most applications.

Q: Does the drum core ferrite construction of the HC2LP-R68-R affect circuit performance?

A: No. Both the wirewound and drum core ferrite constructions deliver identical electrical performance within the specified parameters. The inductance value, current handling, and DC resistance remain constant across the substitution.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts maintain RoHS compliance, MSL 1 rating, and identical ECCN and HTSUS classifications. No compliance barriers exist for substitution.

Q: What inventory status should be considered for procurement decisions?

A: The HC2LP-R68-R has 2797 units in stock compared to 904 units for the obsolete HC2-R68TR-R. The substitute offers superior availability for ongoing production and design support.
