Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASPI-0612FS-3R3M-T is determined by the following critical parameters:

• Inductance Value: Must remain 3.3 µH with ±20% tolerance
• Inductance Tolerance: ±20% specification must be maintained
• Core Type & Material: Drum core, wirewound construction with ferrite material
• Shielding: Shielded configuration required
• Mounting Type: Surface mount only
• Physical Footprint: 6.00mm x 6.00mm base dimensions
• Current Handling: Minimum 1.7 A continuous rating required
• DC Resistance: Lower DCR values are acceptable as they represent improved performance
• Saturation Current: Minimum 1.8 A Isat required
• Compliance: RoHS3 and REACH compliance maintained
• Temperature Range: Operating temperature must support the application requirements

The ASPI-0615FS-3R3M-T2 qualifies as a direct substitute based on matching inductance, tolerance, core type, shielding, mounting configuration, and physical footprint, while offering superior electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0615FS-3R3M-T2 is the manufacturer-recommended substitute for the obsolete ASPI-0612FS-3R3M-T. Both components maintain identical inductance specifications, tolerance, core construction, and shielding characteristics. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The ASPI-0615FS-3R3M-T2 provides enhanced electrical performance with a current rating of 2.8 A versus 1.7 A, and significantly reduced DC resistance of 30 mOhm compared to 137 mOhm maximum. These improvements result in lower power dissipation and improved thermal performance in the application circuit.

Physical compatibility is maintained with identical 6.00mm x 6.00mm footprints. The substitute part exhibits a maximum seated height of 0.087" (2.20mm) compared to 0.047" (1.20mm) for the original part. PCB layout clearance verification is required to confirm vertical space availability.

Both parts maintain RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The substitute part supports an extended operating temperature range of -25°C to 120°C, compared to -40°C to 105°C for the original part. Application temperature requirements must be evaluated to confirm compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0615FS-3R3M-T2 be used as a direct replacement for the ASPI-0612FS-3R3M-T?

A: Yes. Both parts share identical inductance values (3.3 µH), tolerance (±20%), core type (drum core, wirewound ferrite), shielding configuration, and surface mount footprint (6.00mm x 6.00mm). The substitute part is the manufacturer-recommended equivalent.

Q: What are the key differences between these two parts?

A: The primary differences are current rating (2.8 A vs. 1.7 A), DC resistance (30 mOhm vs. 137 mOhm), saturation current (2.8 A vs. 1.8 A), seated height (0.087" vs. 0.047"), operating temperature range (-25°C to 120°C vs. -40°C to 105°C), and product status (active vs. obsolete). The substitute offers superior electrical performance and extended temperature range.

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

A: The ASPI-0615FS-3R3M-T2 has a maximum seated height of 0.087" (2.20mm) compared to 0.047" (1.20mm) for the original part. PCB clearance above the component must be verified to ensure no interference with other board-level components or enclosure constraints.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ASPI-0612FS-3R3M-T and ASPI-0615FS-3R3M-T2 are RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the packaging format for the substitute part?

A: The ASPI-0615FS-3R3M-T2 is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Q: Does the substitute part support the full temperature range of the original part?

A: The substitute part operates from -25°C to 120°C, which does not include the lower temperature limit of -40°C from the original part. Applications requiring operation below -25°C must evaluate alternative solutions or confirm that the reduced lower temperature limit is acceptable for the specific use case.
