Key Parameters

Substitute Part Grouping Explanation

Substitution of the PQ2613-1R0-80-G is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1 µH (exact match required)
• Core material: Ferrite (maintains electromagnetic performance characteristics)
• Shielding configuration: Unshielded (electrical behavior equivalence)
• Mounting type: Surface Mount (PCB integration compatibility)

Secondary Compatibility Parameters:

• Current rating: Minimum 78 A continuous (substitute must support primary application current demands)
• DC resistance: Lower values acceptable (0.42 mOhm represents improved performance)
• Saturation current: Minimum 78 A (maintains headroom for transient conditions)
• Operating temperature range: Overlap with -30°C to 125°C specification

The HC3-1R0-R from Eaton - Electronics Division meets these substitution criteria with equivalent inductance, ferrite core construction, unshielded topology, and surface mount configuration. While the substitute exhibits different core geometry (drum core wirewound versus planar) and slightly lower continuous current rating (78 A versus 80 A), the electrical parameters remain within acceptable substitution boundaries for most applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The PQ2613-1R0-80-G is classified as obsolete. The HC3-1R0-R is classified as active, ensuring long-term availability and manufacturing continuity. For new designs or production continuity, the HC3-1R0-R is the appropriate selection.

Compliance and Regulatory Status

Both parts maintain REACH Unaffected status and EAR99 export classification. The HC3-1R0-R provides additional compliance assurance through ROHS3 certification, meeting current environmental and regulatory requirements for electronics manufacturing.

Electrical Performance Alignment

The HC3-1R0-R delivers equivalent inductance (1 µH) and maintains ferrite core construction with unshielded topology. The substitute exhibits superior DC resistance performance (0.42 mOhm maximum versus 1.2 mOhm), resulting in lower resistive losses and improved thermal efficiency in power conversion applications.

Current Rating Consideration

The HC3-1R0-R continuous current rating of 78 A is 2 A lower than the main part specification of 80 A. For applications operating at or near 80 A continuous current, thermal analysis and margin verification are required. The saturation current differential (78 A substitute versus 120 A main) indicates different transient handling characteristics; applications with significant current overshoot require evaluation.

Temperature Range Limitation

The HC3-1R0-R operating range (-40°C to 85°C) does not extend to the upper temperature limit of the main part (125°C). Applications requiring operation above 85°C require alternative substitute identification or thermal management modifications.

Frequently Asked Questions (FAQ)

Q: Can the HC3-1R0-R directly replace the PQ2613-1R0-80-G in existing designs?

A: Direct replacement is possible for applications operating below 78 A continuous current and below 85°C ambient temperature. The equivalent 1 µH inductance and ferrite unshielded construction ensure electrical compatibility. Physical package dimensions differ (HC3-1R0-R: 30.00mm L × 25.30mm W × 17.50mm H versus PQ2613-1R0-80-G: 26.50mm L × 19.00mm W × 13.20mm H), requiring PCB layout verification. Applications at the upper current or temperature limits of the main part require detailed thermal and electrical analysis before substitution.

Q: What are the key electrical differences between these inductors?

A: Both parts provide 1 µH inductance with ferrite cores and unshielded construction. The HC3-1R0-R exhibits lower DC resistance (0.42 mOhm maximum versus 1.2 mOhm), reducing I²R losses. The main part provides higher saturation current (120 A versus 78 A), offering greater transient current headroom. The main part supports higher ambient temperature operation (125°C maximum versus 85°C).

Q: Are there packaging or mounting compatibility issues?

A: Both parts are surface mount components with nonstandard package geometries. The HC3-1R0-R is larger in all dimensions. PCB footprint, solder pad layout, and thermal management provisions must be verified against the substitute's physical specifications before implementation.

Q: Why is the main part obsolete?

A: The PQ2613-1R0-80-G is classified as obsolete by the manufacturer. The HC3-1R0-R represents the active equivalent from an alternative manufacturer, ensuring procurement continuity and long-term supply availability.

Q: What compliance certifications apply to the substitute?

A: The HC3-1R0-R is ROHS3 compliant and maintains REACH Unaffected status. Both parts carry EAR99 export classification and unlimited moisture sensitivity level (MSL 1) ratings.
