10HC-100 Equivalent & Substitute Parts Reference

Part Overview

The 10HC-100 is a 100 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc., rated for 10 A continuous current with a maximum DC resistance of 30 mOhm. This through-hole radial component is designed for applications requiring fixed inductance in the 100 µH range with moderate current handling capability. The part is currently active in production with 646 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter range for this inductor category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 10HC-100 are qualified based on the following electrical and mechanical criteria:

• Inductance value: 100 µH ±10%
• Current rating: 10 A minimum
• DC resistance: 30 mOhm maximum
• Core type: Ferrite, unshielded drum core
• Mounting: Through-hole radial configuration
• Inductance measurement frequency: 1 kHz

The identified substitutes (IH10BQ101K and IH10EB101K) from Vishay Dale maintain these core specifications. Variations in saturation current (Isat), operating temperature range, and physical dimensions are noted but do not disqualify substitution when the primary electrical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts (10HC-100, IH10BQ101K, and IH10EB101K) share identical primary electrical specifications: 100 µH inductance at ±10% tolerance, 10 A current rating, and 30 mOhm maximum DC resistance. All are ferrite-core, unshielded, through-hole radial inductors tested at 1 kHz.

Selection between these parts should be based on:

• Availability: IH10BQ101K has 1176 units in stock; IH10EB101K has 1228 units in stock; 10HC-100 has 646 units in stock
• Operating temperature requirements: IH10BQ101K specifies -55°C ~ 125°C operating range; operating temperature data is not provided for 10HC-100 or IH10EB101K
• Saturation current margin: IH10BQ101K provides 7 A Isat versus 6 A for 10HC-100, offering additional headroom in transient current conditions
• Physical dimensions: 10HC-100 measures 1.625" Dia × 0.937" L; IH10BQ101K measures 0.935" Dia × 1.625" L (dimensions are transposed)
• Regulatory compliance: All three parts are RoHS non-compliant and REACH unaffected

Frequently Asked Questions (FAQ)

Q: Can IH10BQ101K or IH10EB101K be used as direct replacements for 10HC-100?

A: Yes, both Vishay Dale parts meet the core electrical specifications: 100 µH inductance, 10 A rating, and 30 mOhm maximum DC resistance. Physical dimensions differ (diameter and length are transposed), so PCB layout and mechanical clearance must be verified before substitution.

Q: What is the significance of the different saturation current values?

A: The 10HC-100 has an Isat of 6 A, while IH10BQ101K has 7 A. Saturation current indicates the point at which inductance begins to degrade under high current stress. The higher Isat of IH10BQ101K provides additional margin for transient overcurrent conditions, though both parts are rated for 10 A continuous operation.

Q: Are there any compliance or regulatory differences between these parts?

A: All three parts are RoHS non-compliant and REACH unaffected. No compliance advantage exists between them. If RoHS compliance is required, alternative inductors must be sourced.

Q: Does the operating temperature specification affect substitution?

A: IH10BQ101K explicitly specifies -55°C ~ 125°C operating range. Operating temperature data is not provided for 10HC-100 or IH10EB101K. If operation outside standard industrial temperature ranges is required, IH10BQ101K is the only part with documented temperature specifications.

Q: How do physical dimensions impact substitution?

A: The 10HC-100 is 1.625" diameter × 0.937" length. The IH10BQ101K is 0.935" diameter × 1.625" length. These dimensions are transposed. PCB footprint, lead spacing, and mechanical clearance must be verified to ensure the substitute part fits the intended application without modification to the circuit board layout.
