Substitute Part Grouping Explanation

Substitution of the ASPI-F1010-4R7M-T is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 4.7 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Current rating: 24 A minimum
• Saturation current: 21.4 A minimum
• DC resistance: 5.7 mOhm maximum
• Core material: Alloy powder construction
• Shielding: Shielded configuration required

Mechanical Equivalence Criteria:

• Mounting type: Surface mount
• Physical footprint: 11.90 mm × 11.00 mm × 10.00 mm maximum height
• Package case: Nonstandard form factor

Compliance Equivalence Criteria:

• Operating temperature range: -40°C to 125°C
• RoHS compliance status
• Moisture sensitivity level: MSL 1

The EXL1V1010-4R7-R from Eaton - Electronics Division meets all electrical, mechanical, and compliance requirements for direct substitution. The primary difference is packaging format (Tape & Reel versus Cut Tape) and self-resonant frequency specification availability.

Parameter Comparison

Engineering Selection Recommendations

Both the ASPI-F1010-4R7M-T and EXL1V1010-4R7-R are Active product status components with full compliance to applicable regulatory standards. Selection between these parts is based on the following engineering considerations:

ASPI-F1010-4R7M-T (Abracon LLC):

• Supplied in Cut Tape packaging format
• ROHS3 Compliant certification
• 964 units available in current inventory
• Suitable for applications requiring individual component handling or lower-volume assembly processes

EXL1V1010-4R7-R (Eaton - Electronics Division):

• Supplied in Tape & Reel packaging format
• RoHS Compliant certification
• 1228 units available in current inventory
• Self-resonant frequency specified at 18 MHz, providing additional design verification data
• Suitable for high-volume automated assembly processes
• HTSUS classification: 8504.50.8000

Both components satisfy identical electrical performance requirements across all critical parameters: 4.7 µH inductance at ±20% tolerance, 24 A current rating, 21.4 A saturation current, and 5.7 mOhm maximum DC resistance. Physical footprint and thermal operating range are identical. Selection should be based on packaging format requirements, supply chain availability, and assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Can the EXL1V1010-4R7-R be used as a direct replacement for the ASPI-F1010-4R7M-T in existing designs?

A: Yes. Both components are electrically and mechanically equivalent across all specified parameters. The primary difference is packaging format: the Abracon part is supplied in Cut Tape while the Eaton part is supplied in Tape & Reel. PCB footprint and electrical performance are identical.

Q: What is the significance of the different packaging formats?

A: Cut Tape (CT) packaging is typically used for lower-volume production, prototype builds, and applications requiring individual component handling. Tape & Reel (TR) packaging is optimized for high-volume automated assembly processes. The electrical component itself is identical; only the delivery format differs.

Q: Are there any compliance differences between these two parts?

A: Both parts are RoHS compliant. The Abracon part carries ROHS3 certification while the Eaton part carries RoHS certification. Both meet environmental and hazardous substance restrictions. Both are MSL 1 (Unlimited moisture sensitivity level) and REACH Unaffected.

Q: What does the saturation current specification of 21.4 A mean?

A: Saturation current (Isat) is the DC current level at which the inductor's core material begins to saturate, causing inductance to degrade. The 21.4 A saturation current is below the 24 A current rating, indicating the inductor operates in the linear region up to approximately 21.4 A. Design circuits should account for this parameter when selecting current levels.

Q: Why is the self-resonant frequency specified for the Eaton part but not the Abracon part?

A: The Eaton part datasheet includes self-resonant frequency (18 MHz), while the Abracon part does not specify this parameter. Both parts are functionally equivalent for the specified application. The self-resonant frequency specification provides additional design verification data for high-frequency applications but is not required for substitution equivalence.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both the ASPI-F1010-4R7M-T and EXL1V1010-4R7-R have identical physical dimensions: 11.90 mm length × 11.00 mm width × 10.00 mm maximum seated height. They share the same nonstandard package form factor and are mechanically interchangeable on PCB layouts.

Q: What is the operating temperature range for both parts?

A: Both components operate across the industrial temperature range of -40°C to 125°C. This range is identical and suitable for standard industrial and commercial applications.

Q: Can these inductors be used in high-frequency applications?

A: Both parts are tested and specified at 100 kHz inductance test frequency. The Eaton part specifies a self-resonant frequency of 18 MHz. For applications operating significantly above 100 kHz, the self-resonant frequency becomes a design consideration. Consult detailed frequency response characteristics for specific high-frequency applications.
