Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 15HCR-50 are qualified based on strict equivalence across the following critical parameters:

• Inductance value: 50 µH ±10%
• Current rating: 15 A minimum
• DC resistance: 20 mOhm maximum
• Core type: Drum core, wirewound construction
• Saturation current: 9 A minimum
• Mounting type: Through hole radial configuration
• Package form factor: Horizontal cylinder (open) compatible with 1.000" diameter x 1.625" length envelope

The IH15BQ500K from Vishay Dale meets all specified electrical and mechanical parameters, qualifying it as a direct substitute for the 15HCR-50 in applications where these performance criteria are required.

Parameter Comparison

Engineering Selection Recommendations

Both the 15HCR-50 and IH15BQ500K are Active status components with ROHS3 compliance, suitable for current production designs. Selection between these parts should be based on:

• Availability and lead time requirements
• Supplier qualification and procurement preferences
• PCB layout constraints related to component footprint
• Thermal management considerations in the application circuit

The electrical performance characteristics are equivalent across all specified parameters. Both components are suitable for direct substitution in through-hole applications requiring 50 µH inductance at 15 A current rating.

Frequently Asked Questions (FAQ)

Q: Can the IH15BQ500K replace the 15HCR-50 in my circuit?
