Key Parameters

Substitute Part Grouping Explanation

The ASPI-0310FS-2R2M-T2 qualifies as a direct substitute based on the following critical parameters:

Inductance value remains constant at 2.2 µH with identical ±20% tolerance, ensuring functional equivalence in circuit operation. Core material composition (Nickel Zinc Ferrite) is unchanged, maintaining magnetic performance characteristics. Physical dimensions (3.00mm x 3.00mm x 1.00mm) and surface mount configuration are identical, allowing direct PCB placement compatibility. Shielding configuration remains shielded, preserving electromagnetic isolation properties.

The substitute part demonstrates superior electrical performance: current rating increases from 1.1 A to 1.9 A, DC resistance decreases from 95mOhm to 80mOhm, and saturation current improves from 1.1 A to 1.45 A. Operating temperature range expands from -30°C ~ 100°C to -25°C ~ 120°C. Both parts maintain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations
