AIRD-01-101K Equivalent & Substitute Parts

Part Overview

The AIRD-01-101K is a 100 µH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 2.8 A continuous current with a maximum DC resistance of 95 mOhm. This through-hole radial component operates across the temperature range of -25°C to 85°C and is ROHS3 compliant. The part is currently active in production with 863 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design flexibility, or application-specific performance needs.

Substitute Part Grouping Explanation

The DC630R-104K qualifies as a direct substitute for the AIRD-01-101K based on the following critical parameters:

• Inductance Match: Both parts provide 100 µH with ±10% tolerance
• DC Resistance Match: Both maintain 95 mOhm maximum DC resistance
• Core Type Match: Both use ferrite drum core construction
• Shielding Match: Both are unshielded designs
• Package Match: Both feature radial, vertical cylinder through-hole mounting
• Mechanical Compatibility: Physical dimensions are within acceptable tolerance (AIRD-01: 0.650" Dia × 0.827" Height; DC630R: 0.630" Dia × 0.830" Height)
• Compliance Match: Both are ROHS3 compliant and REACH unaffected

The substitute part offers enhanced current rating (3.21 A vs. 2.8 A) and extended operating temperature range (-55°C to 125°C vs. -25°C to 85°C), providing additional design margin in applications requiring higher thermal or current performance.

Parameter Comparison

Engineering Selection Recommendations

Both the AIRD-01-101K and DC630R-104K are active production components with full ROHS3 compliance and REACH unaffected status, making either suitable for regulated applications. The DC630R-104K provides superior performance margins with 14.6% higher current rating and a 40°C extended upper operating temperature limit, supporting applications with elevated thermal or current demands. Selection between these parts should be based on specific circuit requirements: the AIRD-01-101K for standard applications within its rated specifications, or the DC630R-104K for designs requiring enhanced thermal or current performance headroom.

Frequently Asked Questions (FAQ)

Q: Can DC630R-104K replace AIRD-01-101K in existing designs? A: Yes. Both parts share identical inductance (100 µH ±10%), DC resistance (95 mOhm max), core material (ferrite), shielding (unshielded), and through-hole radial package configuration. Physical dimensions are compatible within standard PCB layout tolerances.

Q: What are the key differences between these parts? A: The DC630R-104K provides higher current rating (3.21 A vs. 2.8 A) and extended operating temperature range (-55°C to 125°C vs. -25°C to 85°C). These represent performance enhancements rather than functional differences.

Q: Are both parts RoHS and REACH compliant? A: Yes. Both AIRD-01-101K and DC630R-104K are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance use.

Q: Will PCB layout require modification when substituting? A: No. Both parts use identical through-hole radial, vertical cylinder packaging. Footprint compatibility is maintained, though the DC630R-104K has slightly smaller diameter (0.630" vs. 0.650"), providing additional layout flexibility.

Q: Which part should be selected for high-temperature applications? A: The DC630R-104K supports operation to 125°C, compared to 85°C for the AIRD-01-101K. For applications exceeding 85°C ambient or requiring thermal margin, the DC630R-104K is the appropriate selection.
