10HCR-100 Equivalent & Substitute Parts Reference

Part Overview

The 10HCR-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 compact form factors. The part is currently active in production with 1053 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same inductance value, current rating, and DC resistance parameters.

Substitute Part Grouping Explanation

Substitute parts for the 10HCR-100 are qualified based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Inductance: 100 µH (exact match required)
• Current Rating: 10 A (exact match required)
• DC Resistance: 30 mOhm maximum (exact match required)
• Core Material: Ferrite, unshielded (exact match required)
• Mounting: Through hole radial configuration (exact match required)
• Inductance Test Frequency: 1 kHz (exact match required)

Identified Substitutes:

• IH10BQ101K (Vishay Dale)
• IH10EB101K (Vishay Dale)

Both substitutes maintain the core electrical specifications and mechanical form factor required for direct replacement in applications designed for the 10HCR-100.

Parameter Comparison

Engineering Selection Recommendations

10HCR-100 (API Delevan Inc.):

• Active product status with confirmed inventory availability
• ROHS3 compliant, suitable for applications with regulatory compliance requirements
• REACH unaffected status confirmed

IH10BQ101K (Vishay Dale):

• Active product status with higher inventory availability (1176 units)
• Saturation current rating of 7 A exceeds the 10HCR-100 specification (6 A)
• RoHS non-compliant; not suitable for applications requiring RoHS3 compliance
• Operating temperature range specified (-55°C ~ 125°C); original part temperature range not provided
• Physical dimensions differ: 0.935" Dia x 1.625" L versus 1.625" Dia x 0.937" L; verify PCB layout compatibility before substitution

IH10EB101K (Vishay Dale):

• Active product status with highest inventory availability (1228 units)
• Incomplete specification data; saturation current, tolerance, and operating temperature not provided
• RoHS and temperature compliance status not specified
• Physical dimensions not provided; dimensional verification required

Frequently Asked Questions (FAQ)

Q: Can IH10BQ101K be used as a direct replacement for 10HCR-100?

A: Electrical specifications are equivalent (100 µH, 10 A, 30 mOhm). However, physical dimensions differ significantly (0.935" Dia x 1.625" L versus 1.625" Dia x 0.937" L). PCB layout and mounting hole spacing must be verified for compatibility. Additionally, IH10BQ101K is RoHS non-compliant, which may disqualify it for applications with regulatory requirements.

Q: What is the significance of the saturation current difference between 10HCR-100 (6 A) and IH10BQ101K (7 A)?

A: Both parts are rated for 10 A continuous current. The saturation current specification indicates the current level at which inductance begins to degrade. IH10BQ101K's higher saturation rating (7 A) provides additional margin before inductance degradation occurs, but does not affect the primary 10 A current rating used for thermal and design calculations.

Q: Is IH10EB101K a viable substitute?

A: IH10EB101K meets the core electrical requirements (100 µH, 10 A, 30 mOhm) but lacks complete specification data. Saturation current, tolerance, operating temperature range, physical dimensions, and compliance certifications are not provided. Obtain complete specifications from the manufacturer before selecting this part for critical applications.

Q: How do physical dimensions affect substitution?

A: The 10HCR-100 and IH10BQ101K have different radial and axial dimensions. PCB layout, mounting hole spacing, and clearance requirements must be verified. A part with equivalent electrical specifications but different physical dimensions may not fit the existing PCB footprint without design modification.

Q: Which substitute part should be selected for RoHS-compliant applications?

A: The 10HCR-100 is ROHS3 compliant and remains the preferred choice for applications with RoHS compliance requirements. IH10BQ101K is RoHS non-compliant. IH10EB101K compliance status is not specified; confirmation from the manufacturer is required.
