Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0315FS-101M-T2 is determined by the following critical parameters:

Inductance value: 100 µH with ±20% tolerance
Package dimensions: 3.00mm x 3.00mm footprint with maximum height of 1.50mm
Current rating: Minimum 210 mA to support the original application
DC resistance: Maximum 4.043 Ohm to maintain circuit performance
Core material: Ferrite construction
Mounting type: Surface mount configuration
Regulatory compliance: ROHS3 certification required

The SRN3015C-101M from Bourns Inc. qualifies as a substitute based on matching inductance value, identical package footprint, ferrite core material, surface mount configuration, and ROHS3 compliance. The substitute part exceeds the minimum current rating requirement at 400 mA and maintains DC resistance within acceptable limits at 4.08 Ohm maximum.

Engineering Selection Recommendations

The SRN3015C-101M qualifies as a direct substitute for the ASPI-0315FS-101M-T2 based on electrical and mechanical compatibility. Both components maintain Active product status and ROHS3 compliance certification. The substitute part provides superior current handling capability at 400 mA versus 210 mA, extended operating temperature range from -55°C to 125°C, and higher self-resonant frequency at 13 MHz. The primary design difference is the reduction from fully shielded to semi-shielded construction; this distinction requires evaluation based on specific electromagnetic interference requirements of the target application. DC resistance values remain functionally equivalent at 4.043 Ohm and 4.08 Ohm maximum respectively. Both components utilize identical 3.00mm x 3.00mm surface mount package dimensions with 1.50mm maximum seated height, ensuring direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SRN3015C-101M replace the ASPI-0315FS-101M-T2 in all applications?

A: The SRN3015C-101M is electrically and mechanically compatible for applications requiring 100 µH inductance in a 3.00mm x 3.00mm surface mount package. The primary consideration is the shielding difference: the original part is fully shielded while the substitute is semi-shielded. Applications sensitive to electromagnetic emissions or susceptible to external electromagnetic interference should evaluate this difference against specific design requirements.

Q: Are the package dimensions identical?

A: Yes. Both the ASPI-0315FS-101M-T2 and SRN3015C-101M share identical footprint dimensions of 3.00mm x 3.00mm with maximum seated height of 1.50mm, ensuring direct PCB compatibility without layout modifications.

Q: What is the difference in current handling capability?

A: The ASPI-0315FS-101M-T2 is rated for 210 mA continuous current with 230 mA saturation current. The SRN3015C-101M is rated for 400 mA continuous current with 330 mA saturation current. The substitute part provides approximately 90% additional current capacity, making it suitable for applications requiring higher current levels.

Q: How do the DC resistance values compare?

A: The ASPI-0315FS-101M-T2 specifies 4.043 Ohm maximum DC resistance, while the SRN3015C-101M specifies 4.08 Ohm maximum. This 0.037 Ohm difference is negligible for most circuit applications and falls within normal manufacturing tolerances for this component category.

Q: What is the significance of the self-resonant frequency difference?

A: The ASPI-0315FS-101M-T2 has a self-resonant frequency of 7.2 MHz, while the SRN3015C-101M operates at 13 MHz. The higher self-resonant frequency of the substitute part indicates improved high-frequency performance characteristics and broader usable frequency range for the inductor.

Q: Are both parts RoHS compliant?

A: Yes. Both the ASPI-0315FS-101M-T2 and SRN3015C-101M carry ROHS3 compliance certification and are suitable for applications requiring restricted substance compliance.
