Substitute Part Grouping Explanation

Substitution of the ASPI-0612FS-220M-T is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Inductance value must remain 22 µH at 100 kHz test frequency
• Inductance tolerance of ±20% is acceptable
• Core material must be ferrite with shielding maintained
• Current rating must meet or exceed 650 mA continuous operation
• DC resistance must not exceed 930 mOhm to maintain circuit performance

Mechanical & Environmental Compatibility:

• Surface mount configuration required
• Package footprint 6.00mm x 6.00mm (XY dimensions) must be maintained
• Height constraint of 1.20mm maximum seated height
• Operating temperature range must encompass -40°C to 105°C minimum
• RoHS3 compliance mandatory

The ASPI-0615FS-220M-T2 satisfies all substitution criteria as a manufacturer-recommended alternative, offering improved electrical performance while maintaining mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0615FS-220M-T2 is the manufacturer-designated substitute for the obsolete ASPI-0612FS-220M-T. Selection of this alternative is supported by the following factors:

Product Status & Availability: The ASPI-0615FS-220M-T2 maintains active production status with 15,882 units in stock, ensuring supply chain continuity compared to the obsolete main part with limited remaining inventory of 836 units.

Electrical Performance: The substitute provides superior electrical characteristics with 1 A current rating versus 650 mA, and significantly reduced DC resistance of 170 mOhm compared to 930 mOhm maximum. These improvements enhance circuit efficiency and thermal performance while maintaining identical 22 µH inductance at 100 kHz test frequency.

Compliance & Certifications: Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Moisture sensitivity level remains at MSL 1 (Unlimited) for both variants.

Mechanical Considerations: The substitute maintains the 6.00mm x 6.00mm footprint for direct PCB layout compatibility. The height increase from 1.20mm to 2.20mm must be evaluated for clearance constraints in the target application. Operating temperature range expansion from -40°C to -25°C minimum and 105°C to 120°C maximum provides broader environmental coverage.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0615FS-220M-T2 be used as a direct replacement for the ASPI-0612FS-220M-T?

A: Yes, the ASPI-0615FS-220M-T2 is the manufacturer-recommended substitute. Both parts share identical inductance (22 µH), tolerance (±20%), core material (ferrite), shielding, and XY footprint dimensions (6.00mm x 6.00mm). The substitute offers improved current handling and reduced DC resistance.

Q: What is the primary difference between these two parts?

A: The main differences are current rating (650 mA vs. 1 A), DC resistance (930 mOhm vs. 170 mOhm), seated height (1.20mm vs. 2.20mm), and product status (obsolete vs. active). The substitute provides superior electrical performance and ongoing availability.

Q: Will the increased height of the substitute part affect my PCB design?

A: The height increase from 1.20mm to 2.20mm must be verified against your specific clearance requirements. If vertical space is constrained, this dimension change requires design review. The XY footprint remains unchanged at 6.00mm x 6.00mm.

Q: Are there any temperature range limitations I should consider?

A: The substitute operates across -25°C to 120°C, compared to the original -40°C to 105°C. If your application requires operation below -25°C, the substitute may not be suitable. For standard industrial applications within -25°C to 105°C, both parts are compatible.

Q: How does the reduced DC resistance of the substitute affect circuit performance?

A: Lower DC resistance (170 mOhm vs. 930 mOhm) reduces resistive losses and heat generation in the inductor. This improves overall circuit efficiency and thermal performance, particularly beneficial in high-frequency switching applications.

Q: Is the packaging format compatible between these parts?

A: Both parts are surface mount components with identical XY dimensions. The substitute is available in Cut Tape (CT) and Digi-Reel packaging, providing standard handling and assembly compatibility.
