Key Parameters

Substitute Part Grouping Explanation

The DC630R-154K from API Delevan Inc. qualifies as a substitute for the AIRD-01-151K based on the following alignment of critical parameters:

• Inductance Match: Both parts provide 150 µH with ±10% tolerance
• Core Type: Both utilize ferrite drum core construction
• Shielding Configuration: Both are unshielded designs
• Mounting Architecture: Both employ through-hole radial vertical cylinder mounting
• Package Compatibility: Both use identical radial vertical cylinder package geometry
• Compliance Alignment: Both are ROHS3 compliant and REACH unaffected

The DC630R-154K demonstrates superior electrical performance characteristics, including higher current rating (2.97 A vs. 1.6 A) and lower DC resistance (111 mOhm vs. 181 mOhm), making it suitable for applications requiring the AIRD-01-151K specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AIRD-01-151K and DC630R-154K are active production components with full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications. The DC630R-154K offers extended operating temperature range (-55°C to 125°C versus -25°C to 85°C) and improved electrical performance through reduced DC resistance and higher current rating, providing design margin for thermal and current stress conditions. Physical dimensions remain compatible within PCB layout tolerances. Selection between these parts should be based on application-specific current requirements, thermal environment, and performance headroom needs.

Frequently Asked Questions (FAQ)

Q: Can the DC630R-154K directly replace the AIRD-01-151K in existing designs?

A: Yes. Both parts share identical inductance values (150 µH ±10%), ferrite drum core construction, unshielded configuration, and through-hole radial vertical cylinder mounting. Physical dimensions are compatible within standard PCB layout tolerances (diameter difference of 0.020", height difference of 0.003").

Q: What are the key differences between these two inductors?

A: The DC630R-154K provides superior performance with 2.97 A current rating versus 1.6 A, lower DC resistance (111 mOhm versus 181 mOhm), and extended operating temperature range (-55°C to 125°C versus -25°C to 85°C). Both maintain identical saturation current (5.6 A) and inductance tolerance (±10%).

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Does the difference in inductance test frequency (1 kHz vs. 10 kHz) affect substitution?

A: The inductance values are specified as 150 µH with ±10% tolerance for both parts. Test frequency differences do not alter the core substitution relationship, as both parts meet the same inductance specification.

Q: What is the saturation current specification, and how does it relate to these parts?

A: Both inductors have a saturation current (Isat) of 5.6 A. This represents the current level at which the inductor begins to lose inductance due to core saturation. The continuous current ratings (1.6 A and 2.97 A respectively) are conservative operating points below saturation.
