Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASPI-0612FS-4R7M-T is determined by the following critical parameters:

• Inductance Value: Must remain 4.7 µH at the specified test frequency of 100 kHz
• Inductance Tolerance: ±20% specification must be maintained
• Core Type and Shielding: Ferrite core with shielding characteristics must be preserved
• Package Footprint: 6.00mm x 6.00mm surface mount footprint compatibility
• Current Handling: Substitute must support the application's current requirements without saturation

The ASPI-0615FS-4R7M-T2 qualifies as a manufacturer-recommended substitute based on matching inductance value, tolerance, core material, shielding type, and identical package footprint dimensions. The substitute offers improved electrical performance characteristics while maintaining mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0615FS-4R7M-T2 is the manufacturer-recommended substitute for the obsolete ASPI-0612FS-4R7M-T. Both components maintain identical inductance specifications, tolerance ratings, core material composition, and shielding characteristics. The substitute is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for electronic component applications. The substitute provides enhanced electrical performance through reduced DC resistance (43mOhm versus 163mOhm) and increased current handling capacity (2.2 A versus 1.55 A), while maintaining the same 6.00mm x 6.00mm footprint for direct board-level compatibility.

The primary design consideration is the increased seated height of the substitute (2.20mm versus 1.20mm). PCB layout and component clearance must be evaluated to confirm mechanical fit within the application's spatial constraints.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0615FS-4R7M-T2 be used as a direct replacement for the ASPI-0612FS-4R7M-T?

A: Yes, the substitute maintains identical inductance value, tolerance, core material, shielding type, and package footprint. The increased seated height must be verified against PCB clearance requirements.

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

A: The substitute offers lower DC resistance (43mOhm versus 163mOhm), higher current rating (2.2 A versus 1.55 A), higher saturation current (2.4 A versus 1.6 A), and an extended upper operating temperature limit (120°C versus 105°C). The substitute is taller by 1.00mm.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both the ASPI-0612FS-4R7M-T and ASPI-0615FS-4R7M-T2 are ROHS3 compliant and REACH unaffected.

Q: What is the inductance test frequency for these components?

A: Both inductors are tested at 100 kHz.

Q: Does the substitute support the same operating temperature range?

A: The substitute supports an extended temperature range of -25°C to 120°C, compared to the original part's -40°C to 105°C range. Applications requiring operation below -25°C must be evaluated separately.

Q: What is the packaging format for the substitute?

A: The ASPI-0615FS-4R7M-T2 is supplied in Tape & Reel (TR) format for automated assembly processes.
