Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0612FS-2R2M-T is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH (primary electrical specification)
• Core Type & Shielding: Must maintain ferrite drum core construction with shielding to preserve electromagnetic performance
• Mounting Configuration: Must be surface mount compatible with equivalent footprint dimensions
• Current Handling: Substitute must support the application's current requirements without saturation
• DC Resistance: Lower DCR values indicate improved efficiency and reduced thermal dissipation
• Temperature Range: Operating temperature capability must meet or exceed application requirements
• Compliance Standards: RoHS3 and REACH compliance maintained across substitutes

The ASPI-0615FS-2R2N-T2 qualifies as a manufacturer-recommended substitute based on matching inductance value, core material, shielding configuration, and surface mount package type, while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0615FS-2R2N-T2 is the manufacturer-recommended substitute for the obsolete ASPI-0612FS-2R2M-T. Both components maintain identical inductance specifications and ferrite shielded drum core construction, ensuring functional compatibility in equivalent circuit applications.

The substitute part offers measurable improvements: current rating increases from 1.8 A to 2.9 A, saturation current rises from 2.4 A to 4.6 A, and DC resistance decreases from 78 mOhm to 24 mOhm. These enhancements provide superior thermal performance and extended current handling capability.

The ASPI-0615FS-2R2N-T2 maintains active product status with full ROHS3 compliance and extended operating temperature range (-25°C to 120°C versus -40°C to 105°C). Height increases from 1.20 mm to 2.20 mm; PCB layout verification is required to confirm clearance compatibility. Both components are available in production quantities with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0615FS-2R2N-T2 directly replace the ASPI-0612FS-2R2M-T in existing designs?

A: Electrical substitution is valid based on matching inductance value (2.2 µH), core material (ferrite), shielding configuration, and surface mount package type. Physical verification is required: the substitute is 1.0 mm taller (2.20 mm vs. 1.20 mm seated height). Confirm PCB clearance and component placement constraints before implementation.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The ASPI-0615FS-2R2N-T2 exhibits 24 mOhm DC resistance compared to 78 mOhm maximum in the original part. Lower resistance reduces I²R losses, decreasing thermal dissipation and improving efficiency in current-carrying applications. This represents a 69% reduction in maximum resistance.

Q: Are there differences in inductance tolerance between these parts?

A: Yes. The ASPI-0612FS-2R2M-T specifies ±20% tolerance, while the ASPI-0615FS-2R2N-T2 specifies ±30% tolerance. For applications requiring tighter inductance control, the original tolerance specification should be evaluated against circuit performance margins.

Q: What packaging differences exist between these components?

A: The original part is supplied in bulk packaging. The substitute is supplied in Tape & Reel (TR) format, standard for automated assembly processes. Both maintain identical footprint dimensions (6.00 mm × 6.00 mm).

Q: Does the extended temperature range of the substitute affect compatibility?

A: The substitute operates from -25°C to 120°C versus -40°C to 105°C for the original. If the application requires operation below -25°C, the substitute does not meet the lower temperature specification. For applications within -25°C to 105°C, the substitute is fully compatible.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ASPI-0612FS-2R2M-T and ASPI-0615FS-2R2N-T2 maintain ROHS3 compliance and are REACH unaffected, meeting current environmental and regulatory requirements.
