Substitute Part Grouping Explanation

Substitution of the ASPI-0612FS-6R8M-T is determined by the following critical parameters:

• Inductance Value: Must remain 6.8 µH with ±20% tolerance
• Core Type & Shielding: Ferrite core with shielding required
• Mounting & Package: Surface mount with compatible 6.00mm x 6.00mm footprint
• Current Handling: Substitute must support minimum 1.35 A rating
• DC Resistance: Lower DCR values are acceptable as they indicate improved performance
• Temperature Range: Operating range must encompass or exceed -40°C to 105°C
• Compliance: RoHS3 compliance required

The ASPI-0615FS-6R8M-T2 qualifies as a direct substitute based on matching inductance, core material, shielding, footprint dimensions, and compliance certifications while offering improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0615FS-6R8M-T2 is the manufacturer-recommended substitute for the obsolete ASPI-0612FS-6R8M-T. Both components maintain identical inductance values, tolerance specifications, core materials, and shielding characteristics. The substitute part offers superior electrical performance with reduced DC resistance (60 mOhm versus 215 mOhm) and higher current ratings (1.8 A versus 1.35 A), providing enhanced thermal efficiency and design margin.

The substitute maintains full RoHS3 compliance and REACH unaffected status. The primary design consideration is the increased seated height (2.20mm versus 1.20mm), which must be verified against PCB layout constraints and available vertical clearance in the assembly.

The ASPI-0615FS-6R8M-T2 is currently in active production with established supply availability, eliminating obsolescence risk associated with the original part number.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0615FS-6R8M-T2 be used as a direct replacement for the ASPI-0612FS-6R8M-T?

A: Yes. Both parts share identical inductance (6.8 µH), tolerance (±20%), core material (ferrite), shielding, and footprint dimensions (6.00mm x 6.00mm). The substitute offers improved performance with lower DC resistance and higher current rating.

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

A: The seated height differs: the original part measures 1.20mm maximum, while the substitute measures 2.20mm maximum. PCB layout and vertical clearance must accommodate this 1.00mm increase.

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8504.50.4000).

Q: Does the lower DC resistance of the substitute affect circuit performance?

A: Lower DC resistance (60 mOhm versus 215 mOhm) reduces resistive losses and heat generation, improving overall circuit efficiency. This represents an enhancement rather than a deviation from the original design intent.

Q: What is the operating temperature difference?

A: The substitute operates across -25°C to 120°C, compared to the original -40°C to 105°C. The substitute provides a higher upper temperature limit but a higher lower temperature limit. Applications requiring operation below -25°C must retain the original part specification.

Q: Is packaging format a consideration for substitution?

A: The original part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. This affects procurement and assembly processes but does not impact component functionality or electrical characteristics.
