Key Parameters

Substitute Part Grouping Explanation

Substitution of the SD8328-150-R is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Inductance value: 15 µH
• Inductance tolerance: ±30%
• Core material: Ferrite
• Shielding: Shielded
• Mounting type: Surface Mount
• Packaging: Tape & Reel (TR)
• Inductance test frequency: 100 kHz

Allowable Variation Parameters:

• Current rating: Substitute must meet or exceed 2.35 A
• DC resistance: Substitute must not exceed 69 mOhm
• Operating temperature range: Substitute must cover or exceed -40°C to 125°C
• RoHS and MSL compliance: Substitute must maintain or improve compliance status

The identified substitute parts SRU8028-150Y and CDRH8D38NP-150NC satisfy all mandatory equivalence criteria. Both parts maintain the 15 µH inductance specification, ±30% tolerance, ferrite core construction, shielded configuration, and surface mount packaging. Variations in current rating, DC resistance, and physical dimensions are within acceptable engineering tolerances for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

SRU8028-150Y (Bourns Inc.) is suitable for applications where the current requirement does not exceed 2 A. This substitute maintains full compliance with RoHS3 and MSL 1 specifications. The SRU8028-150Y exhibits lower DC resistance (66 mOhm) compared to the primary part, resulting in reduced power dissipation. The operating temperature range matches the SD8328-150-R (-40°C to 125°C). Physical dimensions are smaller (8.00mm x 8.00mm footprint), which may provide layout advantages in space-constrained designs. This part is suitable for direct substitution in applications operating below 2 A continuous current.

CDRH8D38NP-150NC (Sumida America Components Inc.) is suitable for applications requiring current ratings up to 2.5 A. This substitute provides the highest current saturation rating (2.75 A) among the three parts, offering additional margin for transient current conditions. DC resistance (67 mOhm Max) is comparable to the primary part. The CDRH8D38NP-150NC maintains RoHS3 compliance and MSL 1 rating. The operating temperature range extends to 100°C maximum, which is 25°C lower than the SD8328-150-R. Physical dimensions match the SRU8028-150Y (8.00mm x 8.00mm footprint) but with greater height (4.00mm). This part is suitable for direct substitution in applications operating up to 2.5 A where the maximum operating temperature does not exceed 100°C.

All three parts maintain Active product status, ensuring continued availability and manufacturing support. Selection between the primary part and substitutes depends on specific application current requirements, thermal operating conditions, and available PCB space.

Frequently Asked Questions (FAQ)

Q: Can the SRU8028-150Y replace the SD8328-150-R in all applications?

A: The SRU8028-150Y is a direct substitute for applications where the continuous current requirement does not exceed 2 A. The primary part is rated for 2.35 A, while the SRU8028-150Y is rated for 2 A. If the application requires current above 2 A, the SRU8028-150Y is not suitable. All other electrical and mechanical parameters are equivalent.

Q: What are the physical dimension differences between these parts?

A: The SD8328-150-R has a footprint of 9.50mm x 8.30mm with a maximum seated height of 3.00mm. Both substitute parts (SRU8028-150Y and CDRH8D38NP-150NC) have a smaller footprint of 8.00mm x 8.00mm. The CDRH8D38NP-150NC has a greater height of 4.00mm compared to 3.10mm for the SRU8028-150Y. PCB layout verification is required when substituting due to these dimensional variations.

Q: Are all three parts RoHS compliant?

A: Yes. The SD8328-150-R is RoHS Compliant. Both substitute parts (SRU8028-150Y and CDRH8D38NP-150NC) are ROHS3 Compliant, which represents an updated compliance standard. All three parts meet RoHS requirements.

Q: What is the difference in DC resistance between these parts?

A: The SD8328-150-R has a maximum DC resistance of 69 mOhm. The SRU8028-150Y has 66 mOhm, and the CDRH8D38NP-150NC has 67 mOhm Max. These differences are minimal and do not significantly impact circuit performance in most applications. Lower DC resistance results in reduced power dissipation.

Q: Can the CDRH8D38NP-150NC be used in applications requiring operation above 100°C?

A: No. The CDRH8D38NP-150NC has a maximum operating temperature of 100°C, while the SD8328-150-R and SRU8028-150Y both operate to 125°C. If the application requires operation above 100°C, the CDRH8D38NP-150NC is not suitable.

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

A: The SD8328-150-R has a saturation current (Isat) of 2 A, the SRU8028-150Y has 1.7 A, and the CDRH8D38NP-150NC has 2.75 A. Saturation current represents the point at which the inductor begins to lose its inductance value due to core saturation. Applications with transient current spikes above the saturation rating may experience inductance degradation. The CDRH8D38NP-150NC provides the highest saturation margin.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. All three parts (SD8328-150-R, SRU8028-150Y, and CDRH8D38NP-150NC) are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What is the MSL rating, and why is it important?

A: All three parts carry an MSL rating of 1 (Unlimited), which indicates unlimited shelf life under standard storage conditions. No special moisture control or baking procedures are required before soldering. This simplifies inventory management and reduces handling complexity.
