Substitute Part Grouping Explanation

Substitution of the ASPI-0316S-100M-T3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 10 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Core type: Ferrite drum core, shielded
• Mounting: Surface mount
• Current rating: minimum 650 mA continuous
• Saturation current: minimum 600 mA
• Operating temperature range: minimum -25°C to 100°C
• RoHS3 compliance

Allowable Variations:

• DC resistance: substitute may be lower (improved performance)
• Physical dimensions: nonstandard packages with equivalent or smaller footprints
• Product status: active or not-for-new-designs alternatives acceptable

The NR3015T100M from Taiyo Yuden meets all mandatory parameters with improved electrical characteristics, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The NR3015T100M qualifies as a direct substitute based on electrical and mechanical equivalence. The substitute part demonstrates superior performance characteristics: 60 mA higher current rating, 100 mA higher saturation current, and 115 mOhm lower DC resistance. The extended operating temperature range to 120°C provides additional thermal margin. Both parts maintain identical inductance specifications, tolerance, core material, shielding configuration, and RoHS3 compliance status.

The slightly smaller physical footprint (3.00mm vs 3.20mm) of the substitute part is compatible with the nonstandard package classification and does not introduce mechanical constraints for surface mount applications. Both parts carry unlimited moisture sensitivity rating (MSL 1), ensuring equivalent reliability in standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can the NR3015T100M directly replace the ASPI-0316S-100M-T3 in existing designs?

A: Yes. Both parts share identical inductance (10 µH ±20%), core material (ferrite), shielding configuration, and mounting type. The substitute meets or exceeds all electrical requirements including current rating, saturation current, and operating temperature range. The marginally smaller footprint (3.00mm vs 3.20mm) is compatible with nonstandard package applications.

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

A: The NR3015T100M exhibits 276 mOhm maximum DC resistance compared to 391 mOhm in the original part. Lower DC resistance reduces resistive losses and heat generation during operation, improving efficiency. This represents an enhancement rather than a deviation from the original specification.

Q: Are there compliance or certification differences between these parts?

A: Both parts are RoHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification. Both maintain unlimited moisture sensitivity rating (MSL 1). No compliance or certification barriers exist for substitution.

Q: Does the product status difference affect substitution suitability?

A: The original part is classified as obsolete, while the substitute is marked "Not For New Designs." The substitute remains available in production quantities (73,837 pcs in stock) and maintains full compliance certifications, making it suitable for both maintenance of existing systems and new production applications where component availability is the primary constraint.

Q: What are the thermal operating differences?

A: The substitute part operates across -25°C to 120°C, extending 20°C above the original part's -25°C to 100°C range. This provides additional thermal margin for applications operating near temperature limits.
