Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASPI-0612FS-100M-T is based on the following critical parameters:

Electrical Compatibility Requirements:

• Inductance value: 10 µH (must match exactly)
• Inductance tolerance: ±20% (must match)
• Core material: Ferrite (must match)
• Shielding: Shielded (must match)
• Inductance test frequency: 100 kHz (must match)

Mechanical Compatibility Requirements:

• Mounting type: Surface Mount (must match)
• Package type: Nonstandard (must match)
• Footprint dimensions: 6.00mm x 6.00mm (must match)

Performance Enhancement Allowances:

• Current rating may be equal to or greater than 1.2 A
• DC resistance may be equal to or lower than 260mOhm
• Operating temperature range may be equal to or wider than -40°C ~ 105°C
• Saturation current may be equal to or greater than 1 A

The ASPI-0615FS-100M-T2 qualifies as a direct substitute because it maintains all electrical and mechanical compatibility parameters while providing improved performance characteristics in current handling and DC resistance.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0615FS-100M-T2 is the manufacturer-recommended substitute for the obsolete ASPI-0612FS-100M-T. Both parts maintain identical electrical specifications for inductance, tolerance, core material, and shielding characteristics. The substitute part is currently in active production status with higher inventory availability (3014 Pcs vs. 1059 Pcs).

The ASPI-0615FS-100M-T2 provides performance improvements including increased current rating (1.5 A vs. 1.2 A), higher saturation current (1.9 A vs. 1 A), and reduced DC resistance (90mOhm vs. 260mOhm). Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

The primary design consideration is the increased seated height of the substitute part (2.20mm vs. 1.20mm). PCB layout and component clearance must accommodate this 1.00mm height difference. The substitute part operates across a wider temperature range (-25°C ~ 120°C vs. -40°C ~ 105°C), which may be advantageous for certain applications but does not extend the lower temperature limit.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0615FS-100M-T2 be used as a direct replacement for the ASPI-0612FS-100M-T?

A: Yes, the ASPI-0615FS-100M-T2 is the manufacturer-recommended substitute. Both parts share identical inductance values, tolerances, core materials, shielding, and footprint dimensions (6.00mm x 6.00mm). The substitute part meets or exceeds all electrical performance requirements of the original part.

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

A: The main differences are product status (obsolete vs. active), current handling capability (1.2 A vs. 1.5 A), DC resistance (260mOhm vs. 90mOhm), and seated height (1.20mm vs. 2.20mm). The substitute part offers improved electrical performance with lower losses and higher current capacity.

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

A: The ASPI-0615FS-100M-T2 has a maximum seated height of 2.20mm compared to 1.20mm for the original part. This 1.00mm increase must be verified against your PCB layout constraints, component clearances, and enclosure dimensions before implementation.

Q: Are both parts RoHS compliant?

A: Yes, both the ASPI-0612FS-100M-T and ASPI-0615FS-100M-T2 are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the packaging difference between these parts?

A: The original part is supplied in standard packaging, while the substitute part is supplied in Tape & Reel (TR) format. Both use nonstandard package types for the inductor itself.

Q: Can I use the ASPI-0615FS-100M-T2 in applications requiring the lower temperature limit of -40°C?

A: No. The substitute part operates from -25°C minimum, which does not meet the -40°C lower temperature requirement of the original part. If your application requires -40°C operation, alternative substitutes must be evaluated or the original part must be sourced from remaining inventory.
