Key Parameters

Substitute Part Grouping Explanation

The ASPI-0315FS-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 electrical equivalence in circuit applications. Physical dimensions are identical (3.00mm x 3.00mm x 1.50mm), confirming PCB layout compatibility. Both components feature shielded drum core construction with surface mount packaging. The substitute part demonstrates improved specifications: current rating increases from 1.28 A to 1.6 A, and DC resistance is specified at 78mOhm maximum versus 60mOhm nominal. Operating temperature range expands from -30°C ~ 100°C to -25°C ~ 120°C. The substitute maintains ROHS3 compliance and MSL 1 rating. Core material differs (ferrite versus nickel zinc ferrite), but both are ferrite-based materials suitable for this inductance class.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0315FS-2R2M-T2 is the appropriate selection for new designs and production transitions due to active product status and extended availability. The obsolete ASPI-0315FSSA-2R2M-T3 should be replaced in existing designs where component refresh cycles permit. Both parts maintain identical ROHS3 and REACH compliance certifications, ensuring regulatory equivalence. The substitute part's higher current rating (1.6 A versus 1.28 A) and expanded operating temperature range (-25°C ~ 120°C versus -30°C ~ 100°C) provide enhanced performance margins. DC resistance specification change (78mOhm maximum versus 60mOhm nominal) requires thermal analysis in power-sensitive applications to confirm acceptable performance.

Frequently Asked Questions (FAQ)

Q: Can ASPI-0315FS-2R2M-T2 be used as a direct replacement for ASPI-0315FSSA-2R2M-T3?

A: Yes. Both components share identical inductance (2.2 µH ±20%), physical dimensions (3.00mm x 3.00mm x 1.50mm), and shielded drum core construction. The substitute part meets or exceeds all critical electrical parameters.

Q: What is the difference in DC resistance between these parts?

A: The main part specifies 60mOhm nominal DCR, while the substitute specifies 78mOhm maximum. This 18mOhm difference may impact thermal performance in high-current applications. Verify thermal budget compatibility in your specific circuit.

Q: Are the packaging formats compatible?

A: The main part uses nonstandard packaging, and the substitute is supplied in Tape & Reel (TR) format. Both are surface mount components with identical footprints and mounting requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the operating temperature difference?

A: The main part operates from -30°C to 100°C, while the substitute operates from -25°C to 120°C. The substitute provides a 5°C lower minimum and 20°C higher maximum operating temperature.
