Substitute Part Grouping Explanation

Substitution eligibility for the SCRH2D14-1R5 is determined by the following criteria:

• Inductance value must be 1.5 µH within ±30% tolerance
• Current rating must meet or exceed 1.6 A continuous rating
• DC resistance must not exceed 71 mOhm
• Shielding configuration must be shielded
• Surface mount package type required
• Operating temperature range must encompass or overlap the -40°C to 125°C specification
• RoHS3 compliance required
• Moisture sensitivity level MSL 1 (Unlimited) required

The ASPI-0310FS-1R5N-T2 from Abracon LLC meets all substitution criteria for the SCRH2D14-1R5.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0310FS-1R5N-T2 is qualified as a direct substitute for the SCRH2D14-1R5 based on the following factors:

• Both components maintain Active product status with full RoHS3 compliance and REACH unaffected designation
• Electrical specifications are equivalent or superior: the substitute provides 2 A current rating versus the 1.6 A requirement, and DC resistance of 70 mOhm meets the 71 mOhm maximum specification
• Physical compatibility is maintained through identical nonstandard package classification and surface mount configuration
• The substitute features a smaller footprint (3.00mm x 3.00mm versus 3.20mm x 3.20mm) and lower profile (1.00mm versus 1.55mm), which may provide layout advantages
• Operating temperature range of the substitute (-25°C to 120°C) covers the majority of the original specification range, with the exception of the lower temperature extreme at -40°C

Selection between these parts should account for the operating temperature requirement. If operation below -25°C is required, the SCRH2D14-1R5 must be retained. For applications within -25°C to 120°C, the ASPI-0310FS-1R5N-T2 provides equivalent performance with potential PCB layout benefits.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0310FS-1R5N-T2 be used as a direct replacement for the SCRH2D14-1R5 in all applications?

A: The ASPI-0310FS-1R5N-T2 is functionally equivalent for applications operating within -25°C to 120°C. If your circuit requires operation at -40°C, the original SCRH2D14-1R5 must be used. Both parts are RoHS3 compliant and share identical inductance, tolerance, and shielding characteristics.

Q: What are the physical differences between these inductors?

A: The ASPI-0310FS-1R5N-T2 has a smaller footprint (3.00mm x 3.00mm versus 3.20mm x 3.20mm) and lower seated height (1.00mm versus 1.55mm). Both use nonstandard surface mount packages. The smaller dimensions may allow for improved PCB layout density.

Q: Are the DC resistance values compatible?

A: Yes. The ASPI-0310FS-1R5N-T2 has a DC resistance of 70 mOhm, which is lower than the 71 mOhm maximum specification of the SCRH2D14-1R5. Lower DC resistance reduces power dissipation and heat generation in the inductor.

Q: What is the saturation current difference, and does it matter?

A: The SCRH2D14-1R5 has an Isat of 1.8 A, while the ASPI-0310FS-1R5N-T2 has an Isat of 1.65 A. Both exceed the 1.6 A continuous current rating. For applications with transient current spikes, verify that peak currents remain below the saturation point of the selected part.

Q: Are both parts available in the same packaging format?

A: Yes. Both the SCRH2D14-1R5 and ASPI-0310FS-1R5N-T2 are supplied in Tape & Reel (TR) packaging for automated assembly. Moisture sensitivity level is MSL 1 (Unlimited) for both parts.
