Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 15HC-50 are qualified based on the following critical parameters that determine functional equivalence:

• Inductance value: 50 µH ±10%
• Current rating: 15 A minimum
• DC resistance: 20 mOhm maximum
• Core material and shielding: Ferrite, unshielded
• Mounting configuration: Through-hole, radial horizontal cylinder
• Physical envelope compatibility: 1.000" Dia x 1.625" L

The IH15BQ500K from Vishay Dale meets these electrical and mechanical requirements and is classified as a direct substitute within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

The 15HC-50 is an active product with established supply. The IH15BQ500K serves as a qualified substitute when the 15HC-50 becomes unavailable or when design requirements permit component sourcing from alternative manufacturers. Both parts share identical electrical specifications for inductance, current rating, and DC resistance. Selection between these parts should be based on availability, lead time, and procurement cost. The 15HC-50 maintains RoHS non-compliant status, while compliance information for the IH15BQ500K is not provided in the available data.

Frequently Asked Questions (FAQ)

Q: What makes the IH15BQ500K a valid substitute for the 15HC-50?

A: The IH15BQ500K matches the critical electrical parameters: 50 µH inductance, 15 A current rating, and 20 mOhm maximum DC resistance. Both components use ferrite drum core construction in unshielded configuration with through-hole radial horizontal cylinder mounting.

Q: Are there any differences in physical dimensions between these parts?

A: The 15HC-50 dimensions are specified as 1.000" Dia x 1.625" L (25.40mm x 41.28mm). Physical dimensions for the IH15BQ500K are not provided in the available technical data. Verification of mechanical fit is required before substitution in space-constrained applications.

Q: Can I use these parts interchangeably in my circuit?

A: Yes, provided that the electrical specifications (50 µH, 15 A, 20 mOhm) meet your circuit requirements and the physical envelope accommodates the component dimensions. Confirm saturation current performance if this parameter is critical to your application.

Q: What is the difference between the HC and IH series designations?

A: The HC series is manufactured by API Delevan Inc., while the IH series is manufactured by Vishay Dale. Both series use identical electrical specifications for this particular part number combination.

Q: Should I consider RoHS compliance when selecting between these parts?

A: The 15HC-50 is RoHS non-compliant. If RoHS compliance is required for your application, verify the compliance status of the IH15BQ500K with the manufacturer before selection.
