Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-7318-R10M-T is determined by the following critical parameters:

Inductance Value: 100 nH (primary electrical specification)
Current Rating: 30 A minimum continuous current capability
DC Resistance: 1.7 mOhm maximum to maintain equivalent power loss characteristics
Saturation Current: 50 A minimum to prevent core saturation under transient conditions
Core Type & Shielding: Ferrite drum core with shielding to maintain electromagnetic isolation
Operating Temperature: -55°C to 125°C range compatibility
Mounting Type: Surface mount configuration for PCB integration
Compliance: ROHS3 compliance for regulatory alignment

The ASPI-7318-R10N-T qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the allowed tolerance specifications.

Engineering Selection Recommendations

The ASPI-7318-R10N-T is the qualified substitute for the obsolete ASPI-7318-R10M-T. Both components are manufactured by Abracon LLC within the same ASPI-7318 series and maintain identical electrical performance specifications across all critical parameters: inductance value, current rating, DC resistance, saturation current, and operating temperature range.

The primary distinction is product status: the ASPI-7318-R10N-T is currently active in production with confirmed inventory availability (1649 pcs), whereas the ASPI-7318-R10M-T is obsolete. The substitute exhibits a wider inductance tolerance (±30% versus ±20%), which remains acceptable for applications where the original ±20% tolerance was not a binding design requirement.

Both parts maintain ROHS3 compliance and identical physical dimensions, ensuring direct PCB footprint compatibility without layout modifications. The substitute is available in Cut Tape (CT) packaging, supporting standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-7318-R10N-T be used as a direct replacement for the ASPI-7318-R10M-T?

A: Yes. Both components share identical inductance values (100 nH), current ratings (30 A), DC resistance (1.7 mOhm max), saturation current (50 A), core material (ferrite), shielding configuration, operating temperature range, and physical dimensions. The substitute is electrically and mechanically compatible.

Q: What is the difference in inductance tolerance between these parts?

A: The ASPI-7318-R10M-T specifies ±20% tolerance, while the ASPI-7318-R10N-T specifies ±30% tolerance. If your circuit design requires the tighter ±20% tolerance specification, component selection must account for this difference. For applications where inductance tolerance is not a critical design parameter, the wider tolerance of the substitute is acceptable.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical environmental and regulatory classifications (ECCN: EAR99, HTSUS: 8504.50.4000).

Q: What is the packaging difference?

A: The ASPI-7318-R10M-T packaging is listed as nonstandard. The ASPI-7318-R10N-T is supplied in Cut Tape (CT) packaging, which is standard for automated assembly processes and offers improved handling and storage characteristics.

Q: Is the substitute currently available?

A: Yes. The ASPI-7318-R10N-T is an active product with 1649 pcs in stock, ensuring supply chain continuity compared to the obsolete ASPI-7318-R10M-T.
