AIRD-02-100K Equivalent & Substitute Parts

Part Overview

The AIRD-02-100K is a 10 µH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 11.4 A continuous current with a maximum DC resistance of 9 mOhm. This through-hole radial component is designed for applications requiring fixed inductance in the 10 µH range with moderate current handling capability. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same inductance value, current rating, and mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-02-100K is determined by strict equivalence across the following critical parameters:

• Inductance Value: 10 µH ±10% tolerance
• Current Rating: Minimum 11.4 A continuous
• DC Resistance: Maximum 9 mOhm
• Core Type: Ferrite drum core, unshielded
• Mounting Configuration: Through-hole radial, vertical cylinder orientation
• Compliance: ROHS3 compliant

The DC780R-103K from API Delevan Inc. meets all substitution criteria. Both parts share identical inductance specifications, current ratings, and DC resistance limits. Both employ ferrite drum core construction with unshielded configuration and through-hole radial mounting. Mechanical dimensions vary slightly but remain compatible with standard through-hole PCB layouts designed for radial inductors in this package class.

Parameter Comparison

Engineering Selection Recommendations

Both the AIRD-02-100K and DC780R-103K are active production components with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications. The DC780R-103K provides extended operating temperature range (-55°C to 125°C versus -25°C to 85°C) and higher saturation current (34.5 A versus 30 A), making it suitable for applications requiring broader thermal or transient current margins. Selection between these parts should be based on application-specific temperature and current stress requirements within the specified operating envelope. Both parts maintain equivalent electrical performance at rated specifications and are suitable for direct substitution in through-hole PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the DC780R-103K replace the AIRD-02-100K in all applications?

A: Yes, provided the application operates within the AIRD-02-100K temperature range (-25°C to 85°C). The DC780R-103K meets or exceeds all critical electrical parameters: inductance, current rating, and DC resistance. Both parts are mechanically compatible with radial through-hole PCB layouts.

Q: What are the physical dimension differences between these parts?

A: The AIRD-02-100K has a diameter of 0.827" (21.00 mm) and height of 0.827" (21.00 mm). The DC780R-103K has a diameter of 0.772" (19.60 mm) and height of 0.831" (21.10 mm). Both fit standard radial inductor footprints; verify PCB layout clearances if space is constrained.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. No compliance barriers exist for substitution.

Q: When should I choose the DC780R-103K over the AIRD-02-100K?

A: Select the DC780R-103K when the application requires extended temperature operation beyond 85°C or when higher saturation current margin (34.5 A versus 30 A) is beneficial for transient stress conditions.

Q: Is the ±10% inductance tolerance maintained in both parts?

A: Yes. Both the AIRD-02-100K and DC780R-103K maintain ±10% inductance tolerance at 1 kHz test frequency, ensuring equivalent circuit performance.
