Key Parameters

Substitute Part Grouping Explanation

The ASPI-0315FS-100M-T2 qualifies as a direct substitute based on the following critical parameters:

Inductance value remains constant at 10 µH with identical ±20% tolerance, ensuring functional equivalence in circuit applications. Both parts maintain identical physical footprint dimensions (3.00mm x 3.00mm x 1.50mm maximum height), confirming mechanical compatibility on printed circuit boards. Shielding configuration is preserved across both parts, maintaining electromagnetic isolation characteristics. Surface mount mounting type is consistent between main and substitute part.

The substitute part demonstrates improved specifications in current handling capacity (770 mA versus 750 mA) and expanded operating temperature range (-25°C to 120°C versus -30°C to 100°C). The substitute part carries active product status with confirmed inventory availability, addressing the obsolescence of the main part number.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0315FS-100M-T2 is the designated substitute for the obsolete ASPI-0315FSSA-100M-T3. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production environments. The substitute part carries active product status with established supply chain availability, eliminating obsolescence risk.

DC resistance differential (325mOhm maximum versus 200mOhm) requires circuit-level evaluation in applications where power dissipation or voltage drop characteristics are critical design parameters. The expanded operating temperature range of the substitute part provides additional thermal margin for applications operating at elevated ambient conditions.

Frequently Asked Questions (FAQ)

Q: Can ASPI-0315FS-100M-T2 be used as a direct replacement for ASPI-0315FSSA-100M-T3?

A: Yes. Both parts share identical inductance value (10 µH), tolerance (±20%), physical dimensions (3.00mm x 3.00mm), shielding configuration, and surface mount package type. The substitute part is actively manufactured and stocked.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The substitute part specifies 325mOhm maximum DCR compared to 200mOhm in the main part. This 62.5% increase in resistance will result in proportionally higher power dissipation at equivalent current levels. Circuit designs operating near maximum current ratings (750 mA) should evaluate thermal performance impact.

Q: Are there packaging differences between these parts?

A: The main part uses nonstandard packaging, while the substitute part is supplied in Tape & Reel (TR) format. Both maintain identical physical footprint and mounting characteristics on PCBs. Tape & Reel packaging provides improved handling and automated assembly compatibility.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the current saturation difference between these parts?

A: The main part specifies 820mA saturation current, while the substitute part specifies 720mA. This 100mA difference should be evaluated in applications where inductor saturation characteristics influence circuit performance or stability margins.
