Key Parameters

Substitute Part Grouping Explanation

Substitution of the HC5-2R2-R is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Inductance value must equal 2.2 µH at 100 kHz test frequency
• Inductance tolerance of ±20% is acceptable
• Current rating must meet or exceed 14 A continuous operation
• DC resistance must not exceed 5.6 mOhm maximum to maintain circuit performance
• Saturation current (Isat) must support the application's peak current requirements

Mechanical Compatibility Criteria:

• Surface mount package with identical footprint dimensions (12.50 mm × 12.50 mm)
• Height must not exceed 5.30 mm to ensure PCB assembly compatibility
• Moisture sensitivity level MSL 1 or better

Application-Specific Consideration: The HC5-2R2-R features electromagnetic shielding. Substitute parts may have different shielding characteristics (shielded or unshielded), which affects EMI performance and must be evaluated based on circuit requirements.

The HCF1305-2R2-R qualifies as a substitute based on matching inductance, tolerance, footprint, and height specifications, with superior current rating and lower DC resistance.

Engineering Selection Recommendations

HCF1305-2R2-R as Primary Substitute:

The HCF1305-2R2-R is the qualified substitute for the obsolete HC5-2R2-R based on the following engineering factors:

1. Electrical Performance: The HCF1305-2R2-R delivers superior electrical characteristics with 16.3 A continuous current rating (exceeding the 14 A requirement) and 3.1 mOhm maximum DC resistance (lower than the 5.6 mOhm specification). These improvements provide enhanced thermal performance and reduced power dissipation in the application circuit.

2. Mechanical Compatibility: Identical footprint dimensions (12.50 mm × 12.50 mm) and reduced height (5.00 mm vs. 5.30 mm maximum) ensure direct PCB assembly compatibility without layout modifications.

3. Product Status and Compliance: The HCF1305-2R2-R is an active product with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory alignment for new designs and production continuity.

4. Temperature Range: Extended operating temperature range (-40°C to 125°C vs. -25°C to 125°C) provides additional thermal margin for demanding applications.

Shielding Consideration: The HCF1305-2R2-R is unshielded, whereas the HC5-2R2-R is shielded. In applications where electromagnetic shielding is critical to circuit performance or EMI compliance, the unshielded characteristic of the substitute must be evaluated against specific circuit requirements and PCB layout strategies.

Frequently Asked Questions (FAQ)

Q: Can the HCF1305-2R2-R directly replace the HC5-2R2-R without circuit modifications?

A: The HCF1305-2R2-R meets all critical electrical and mechanical parameters for direct substitution. The identical inductance value (2.2 µH), matching tolerance (±20%), compatible current ratings, and identical footprint dimensions enable direct PCB assembly replacement. However, the change from shielded to unshielded construction requires evaluation of EMI performance in the specific application circuit.

Q: What is the impact of the lower DC resistance in the HCF1305-2R2-R?

A: The HCF1305-2R2-R exhibits 3.1 mOhm maximum DC resistance compared to 5.6 mOhm in the HC5-2R2-R. This 45% reduction in resistance decreases power dissipation (I²R losses) and improves thermal performance, resulting in lower operating temperatures and enhanced reliability in the application circuit.

Q: Are there differences in saturation current between these parts?

A: The HC5-2R2-R has an Isat of 16 A, while the HCF1305-2R2-R has an Isat of 15 A. Both values exceed the 14 A continuous current rating. For applications operating near saturation limits, the HC5-2R2-R provides marginally higher saturation headroom. The HCF1305-2R2-R's higher continuous current rating (16.3 A) compensates for this difference in typical operating scenarios.

Q: Does the unshielded design of the HCF1305-2R2-R affect EMI performance?

A: The HCF1305-2R2-R is unshielded, whereas the HC5-2R2-R is shielded. Shielding reduces electromagnetic radiation and susceptibility to external interference. In applications requiring strict EMI control, the unshielded characteristic may necessitate additional circuit-level filtering or PCB layout optimization. Evaluation against specific EMI standards and circuit requirements is necessary.

Q: What is the significance of the extended temperature range in the HCF1305-2R2-R?

A: The HCF1305-2R2-R operates from -40°C to 125°C, compared to -25°C to 125°C for the HC5-2R2-R. The extended lower temperature limit provides additional thermal margin for applications in cold environments or with stringent temperature cycling requirements, enhancing component reliability in demanding thermal conditions.

Q: Is the HCF1305-2R2-R available in the same packaging format?

A: The HCF1305-2R2-R is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly. The HC5-2R2-R packaging format is not specified in the available data. Tape & Reel packaging is compatible with automated PCB assembly processes and is the industry standard for surface mount components.

Q: What regulatory compliance advantages does the HCF1305-2R2-R provide?

A: The HCF1305-2R2-R carries ROHS3 compliance certification and REACH unaffected status, ensuring compliance with current environmental and hazardous substance regulations. These certifications support product qualification for regulated markets and long-term supply chain sustainability.
