Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0315FS-150M-T2 is determined by the following critical parameters:

• Inductance value: 15 µH with ±20% tolerance
• Current rating: minimum 650 mA to support the original application
• DC resistance: maximum 455 mOhm to maintain circuit performance
• Package dimensions: 3.00mm x 3.00mm footprint with 1.50mm maximum height
• Core material: Ferrite construction
• Mounting type: Surface mount configuration
• Shielding: Shielded or semi-shielded construction acceptable for EMI containment

The SRN3015C-150M from Bourns Inc. meets these substitution criteria with compatible electrical and mechanical specifications.

Engineering Selection Recommendations

The SRN3015C-150M qualifies as a direct substitute for the ASPI-0315FS-150M-T2 based on the following engineering criteria:

Both components maintain Active product status and are ROHS3 compliant with REACH unaffected classification, ensuring regulatory compliance for current and future applications. The substitute part provides superior electrical performance with lower DC resistance (372 mOhm vs. 455 mOhm maximum) and higher current saturation rating (850 mA vs. 660 mA), delivering improved thermal efficiency and headroom in the application circuit. Identical package footprint and height enable direct PCB layout compatibility without redesign. The extended operating temperature range (-55°C to 125°C versus -25°C to 120°C) provides additional environmental margin. Semi-shielded construction maintains adequate EMI containment for typical applications requiring shielded inductors.

Frequently Asked Questions (FAQ)

Q: Can the SRN3015C-150M replace the ASPI-0315FS-150M-T2 in existing designs?

A: Yes. Both components share identical inductance (15 µH ±20%), package dimensions (3.00mm x 3.00mm x 1.50mm), and mounting type (surface mount). The substitute part exceeds the original current rating and provides lower DC resistance, making it electrically compatible for direct substitution.

Q: What is the difference between shielded and semi-shielded construction?

A: Shielded inductors provide complete magnetic field containment, while semi-shielded inductors offer partial containment with reduced shielding coverage. For most applications, semi-shielded construction provides sufficient EMI suppression while maintaining comparable performance characteristics.

Q: Are there any thermal considerations when substituting these parts?

A: The SRN3015C-150M operates across a wider temperature range (-55°C to 125°C) compared to the ASPI-0315FS-150M-T2 (-25°C to 120°C). The lower maximum DC resistance of the substitute part (372 mOhm vs. 455 mOhm) results in reduced resistive heating, providing improved thermal performance in the application.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level), ensuring equivalent regulatory compliance for industrial and commercial applications.

Q: What is the current saturation difference between these inductors?

A: The ASPI-0315FS-150M-T2 has a saturation current of 660 mA, while the SRN3015C-150M reaches 850 mA. The substitute part provides 190 mA additional saturation margin, allowing operation at higher current levels before inductance degradation occurs.
