HC5-1R2-R Equivalent & Substitute Parts

Part Overview

The HC5-1R2-R is a 1.2 µH shielded wirewound inductor manufactured by Eaton - Electronics Division in a nonstandard surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The part operates across an industrial temperature range of -25°C to 125°C and features unlimited moisture sensitivity rating (MSL 1).

Key Parameters

Substitute Part Grouping Explanation

The HCF1305-1R2-R qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Inductance value: 1.2 µH (identical)
• Inductance tolerance: ±20% (identical)
• Inductance test frequency: 100 kHz (identical)
• Mounting type: Surface Mount (identical)
• Package dimensions: 0.492" L x 0.492" W / 12.50mm x 12.50mm (identical)
• Moisture sensitivity level: MSL 1 (identical)

Differing Parameters:

• Shielding: HC5-1R2-R is shielded; HCF1305-1R2-R is unshielded
• Core material: HC5-1R2-R uses unspecified core; HCF1305-1R2-R uses ferrite core
• Current rating: HCF1305-1R2-R rated for 22 A with 1.9mOhm max DCR
• Operating temperature: HCF1305-1R2-R extends to -40°C (lower minimum)
• Product status: HCF1305-1R2-R is active

Substitution is valid where shielding requirements are not critical to circuit performance and where the unshielded drum core configuration is acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

The HCF1305-1R2-R is the designated substitute for the obsolete HC5-1R2-R based on electrical parameter equivalence and active product status. Selection of this substitute is appropriate when:

• The application does not require electromagnetic shielding properties
• The unshielded ferrite drum core configuration is compatible with circuit layout and EMI considerations
• The extended lower operating temperature limit (-40°C versus -25°C) provides additional thermal margin
• RoHS compliance is required for the end application

The HCF1305-1R2-R maintains identical inductance specifications and tolerance at the standard test frequency, ensuring functional equivalence for inductance-dependent circuit behavior. The active product status ensures long-term availability and supply chain continuity compared to the obsolete HC5-1R2-R.

Frequently Asked Questions (FAQ)

Q: Can HCF1305-1R2-R replace HC5-1R2-R in all applications?

A: Substitution is valid where shielding is not a circuit requirement. The unshielded construction of HCF1305-1R2-R may introduce different EMI coupling characteristics. Circuit-level evaluation is necessary if electromagnetic isolation is critical.

Q: What is the primary difference between these parts?

A: The HC5-1R2-R features shielding and uses an unspecified core material, while the HCF1305-1R2-R is unshielded with a ferrite drum core. Both maintain identical 1.2 µH inductance and ±20% tolerance at 100 kHz.

Q: Are the physical dimensions compatible?

A: Yes. Both parts share identical footprint dimensions of 0.492" x 0.492" (12.50mm x 12.50mm). The HCF1305-1R2-R is 0.012" (0.30mm) shorter in seated height, which is negligible for most PCB assembly applications.

Q: Does HCF1305-1R2-R offer better temperature performance?

A: The HCF1305-1R2-R extends the minimum operating temperature to -40°C compared to -25°C for the HC5-1R2-R, providing a 15°C wider lower temperature range. Both support 125°C maximum.

Q: Is RoHS compliance a factor in substitution?

A: The HCF1305-1R2-R is RoHS compliant. If the end application requires RoHS certification, this substitute meets that requirement. The HC5-1R2-R RoHS status is not specified.

Q: What current handling capability should be considered?

A: The HCF1305-1R2-R is rated for 22 A with 1.9mOhm maximum DC resistance. The HC5-1R2-R current rating is not specified. If the application requires current handling specifications, the HCF1305-1R2-R provides documented performance.
