Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCP1104-R56-R is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 560 nH ±20%
• Current rating: minimum 25 A continuous
• Saturation current: minimum 32 A
• DC resistance: maximum 1.8 mOhm
• Core material: Iron Powder
• Operating temperature range: -55°C to 125°C minimum
• Mounting type: Surface Mount
• Inductance test frequency: 100 kHz

Secondary Consideration:

• Shielding configuration may differ based on application electromagnetic compatibility requirements

The HCM1104-R56-R qualifies as a direct substitute based on matching all primary electrical parameters. The primary distinction is the shielded configuration of the HCM1104-R56-R versus the unshielded HCP1104-R56-R, which represents a functional enhancement rather than a limitation for most applications.
