Substitute Part Grouping Explanation

The ASPI-0615FS-470M-T2 qualifies as a direct substitute based on the following critical parameters:

• Inductance Match: Both parts specify 47 µH at 100 kHz test frequency with ±20% tolerance
• Core Material & Shielding: Identical ferrite core material with shielded configuration
• Mounting & Package: Both are surface mount components with nonstandard package dimensions
• Compliance: Both maintain ROHS3 compliance and REACH unaffected status
• Footprint Compatibility: Identical lateral dimensions (6.00mm x 6.00mm), with height difference of 1.0mm (1.20mm vs 2.20mm)

The substitute part offers superior electrical performance with higher current rating (800 mA vs 460 mA) and significantly lower DC resistance (370mOhm vs 1.25Ohm), making it suitable for applications requiring the original part's specifications while providing enhanced capability margin.

Engineering Selection Recommendations

The ASPI-0615FS-470M-T2 is the recommended substitute for the obsolete ASPI-0612FS-470M-T. Selection is based on:

• Product Status: The substitute maintains active product status with established supply chain availability, whereas the original part is obsolete
• Regulatory Compliance: Both parts maintain identical ROHS3 and REACH compliance certifications, ensuring regulatory continuity
• Electrical Compatibility: Matching inductance value and tolerance at the specified test frequency ensures functional equivalence in circuit applications
• Performance Enhancement: The substitute provides improved current handling capability and reduced DC resistance, offering superior performance margins without compromising the original design intent
• Mechanical Fit: Identical lateral footprint (6.00mm x 6.00mm) ensures PCB layout compatibility; the 1.0mm height increase requires verification of available clearance in the assembly

Frequently Asked Questions (FAQ)

Q: Can ASPI-0615FS-470M-T2 be used as a direct replacement in existing designs?

A: Yes, for applications operating at or below 460 mA. The matching inductance value, tolerance, core material, and shielding configuration ensure functional equivalence. PCB layout compatibility is maintained due to identical lateral dimensions. Verify available vertical clearance, as the substitute is 1.0mm taller.

Q: What are the key differences between these parts?

A: The substitute offers higher current rating (800 mA vs 460 mA), lower DC resistance (370mOhm vs 1.25Ohm), higher saturation current (800 mA vs 520 mA), and extended upper operating temperature (120°C vs 105°C). The original part is obsolete; the substitute is active.

Q: Are there packaging differences?

A: The original part uses standard packaging notation, while the substitute is supplied in Tape & Reel (TR) format. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Does the height difference affect PCB assembly?

A: The substitute is 1.0mm taller (2.20mm vs 1.20mm seated height). Verify available clearance above the component location on the PCB. If clearance is insufficient, alternative solutions must be evaluated.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in production environments.
