Engineering Selection Recommendations

AISC-1008F-2R2J-T (Abracon LLC) - Direct Substitute

The AISC-1008F-2R2J-T is classified as a direct manufacturer substitute. This part maintains active product status, ensuring long-term availability and supply chain stability. It matches all primary compatibility criteria: 2.2 µH inductance, 1008 (2520 Metric) package, surface mount configuration, ferrite core, and unshielded design. The current rating of 520 mA exceeds the 500 mA requirement of the original part. The inductance tolerance of ±5% is tighter than the original ±10%, providing improved precision. Operating temperature range (-40°C ~ 85°C) matches the original specification. ROHS3 compliance and REACH Unaffected status satisfy regulatory requirements. This part is recommended as the primary replacement option.

PM1008-2R2K-RC (Bourns Inc.) - Similar Substitute

The PM1008-2R2K-RC is classified as a similar manufacturer substitute. This part maintains active product status and meets all primary compatibility criteria. However, the current rating of 250 mA falls below the 500 mA requirement of the original part, making this substitute suitable only for applications where the actual circuit current demand does not exceed 250 mA. The DC resistance of 2.8 Ohm is significantly higher than the original 600 mOhm specification. The operating temperature range extends to 125°C, exceeding the original -40°C ~ 85°C range. ROHS3 compliance and REACH Unaffected status are satisfied. This part is recommended only when current requirements are confirmed to be 250 mA or lower.

Frequently Asked Questions (FAQ)

Q: Can the AISC-1008F-2R2J-T directly replace the 1008HC-222EKFS without circuit modification?

A: The AISC-1008F-2R2J-T meets all primary compatibility parameters and exceeds the current rating requirement. Direct substitution is supported from a mechanical and electrical standpoint. However, the higher DC resistance (1.15 Ohm vs. 600 mOhm) may affect circuit performance in applications sensitive to inductor losses. Circuit validation is determined by application-specific requirements.

Q: Why is the PM1008-2R2K-RC listed as a similar substitute rather than a direct substitute?

A: The PM1008-2R2K-RC current rating of 250 mA is below the original 500 mA specification. This part is suitable only for circuits operating at 250 mA or lower. Additionally, the DC resistance of 2.8 Ohm is substantially higher than the original 600 mOhm, which may introduce unacceptable losses in certain applications.

Q: Are all substitute parts available in the same packaging format?

A: The AISC-1008F-2R2J-T is supplied in Cut Tape (CT) & Digi-Reel® packaging. The PM1008-2R2K-RC is supplied in Tape & Reel (TR) packaging. Both formats are standard for surface mount components and are compatible with automated assembly equipment. Packaging format selection depends on production volume and assembly line requirements.

Q: Do all parts meet the same regulatory compliance standards?

A: All three parts (original and substitutes) are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.

Q: What is the impact of inductance tolerance differences on circuit performance?

A: The original part specifies ±10% tolerance. The AISC-1008F-2R2J-T offers ±5% tolerance, providing tighter inductance control. The PM1008-2R2K-RC maintains ±10% tolerance. Tighter tolerance may improve circuit performance in applications sensitive to inductance variation, but circuit-level impact depends on specific application requirements.

Q: Are there any height or dimensional differences between substitute parts?

A: The 1008HC-222EKFS has a maximum seated height of 0.083" (2.10mm). The AISC-1008F-2R2J-T has a maximum seated height of 0.090" (2.29mm). The PM1008-2R2K-RC has a maximum seated height of 0.071" (1.80mm). These dimensional variations must be evaluated against PCB layout constraints and clearance requirements in the target application.
