Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASPI-0315FS-1R5N-T2 is determined by the following critical parameters:

• Inductance value of 1.5 µH within acceptable tolerance range
• Current rating capability meeting or exceeding 1.7 A continuous operation
• DC resistance not exceeding 65 mOhm to maintain thermal and efficiency characteristics
• Ferrite core material for electromagnetic performance consistency
• Surface mount package with 3.00mm x 3.00mm footprint and 1.50mm maximum height
• Operating temperature range compatibility with -25°C to 120°C specification
• RoHS3 compliance and REACH unaffected status for regulatory alignment

The SRN3015C-1R5M from Bourns Inc. qualifies as a substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The SRN3015C-1R5M substitute meets all critical electrical and mechanical requirements for direct replacement of the ASPI-0315FS-1R5N-T2. Both components are active products with ROHS3 compliance and REACH unaffected status. The substitute provides improved performance characteristics including higher current rating (2.7 A versus 1.7 A), lower DC resistance (43 mOhm versus 65 mOhm maximum), and tighter inductance tolerance (±20% versus ±30%). The extended operating temperature range (-55°C to 125°C) of the substitute accommodates the original specification range. Identical package footprint and height ensure mechanical compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the SRN3015C-1R5M be used as a direct replacement for the ASPI-0315FS-1R5N-T2?

A: Yes. Both components share identical inductance value (1.5 µH), package dimensions (3.00mm x 3.00mm x 1.50mm), and ferrite core material. The substitute meets or exceeds all electrical specifications of the original part.

Q: What is the difference in shielding between these two inductors?

A: The ASPI-0315FS-1R5N-T2 is fully shielded, while the SRN3015C-1R5M is semi-shielded. Shielding level selection depends on electromagnetic interference requirements in the specific application circuit.

Q: Are there any temperature range limitations when substituting?

A: No. The SRN3015C-1R5M operating range (-55°C to 125°C) encompasses the ASPI-0315FS-1R5N-T2 range (-25°C to 120°C), ensuring compatibility across all specified operating conditions.

Q: How do the DC resistance values compare?

A: The SRN3015C-1R5M has lower maximum DC resistance (43 mOhm) compared to the ASPI-0315FS-1R5N-T2 (65 mOhm), resulting in reduced power dissipation and improved thermal performance in the substitute.

Q: Are both parts RoHS compliant?

A: Yes. Both the ASPI-0315FS-1R5N-T2 and SRN3015C-1R5M are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the current rating difference and does it affect substitution?

A: The SRN3015C-1R5M has a higher continuous current rating (2.7 A) than the ASPI-0315FS-1R5N-T2 (1.7 A). This provides additional design margin and does not prevent substitution; the substitute can safely handle the original part's current requirements.
