Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PM528S-150-RC are qualified based on the following critical parameters that determine functional equivalence:

Inductance value must remain 15 µH within the ±30% tolerance specification. Current rating must meet or exceed 1.3 A to support the same load conditions. DC resistance must not exceed 100 mOhm to maintain equivalent power dissipation characteristics. Core material must be ferrite with shielding to preserve electromagnetic performance. Physical dimensions must match 5.80mm x 5.80mm footprint with maximum seated height of 3.00mm for PCB compatibility. Operating temperature range must span -40°C to 125°C. Saturation current performance must be comparable to support circuit reliability. Surface mount packaging and nonstandard case type must be maintained. RoHS3 compliance and MSL 1 rating must be preserved for manufacturing and environmental requirements.

Parameter Comparison

Engineering Selection Recommendations

The SRR5028-150Y qualifies as a direct substitute for the PM528S-150-RC based on electrical and mechanical parameter equivalence. Both components are manufactured by Bourns Inc. and maintain active product status. The substitute part demonstrates equal or superior performance across all critical parameters: current rating increases from 1.3 A to 1.37 A, saturation current increases from 1.1 A to 1.15 A, while DC resistance remains at 100 mOhm maximum. Physical footprint and height specifications are identical, ensuring PCB layout compatibility without redesign. Both parts maintain ROHS3 compliance and MSL 1 rating, supporting equivalent manufacturing and environmental requirements. The substitute part is available in higher inventory quantity (1580 Pcs versus 953 Pcs), providing supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: Can the SRR5028-150Y replace the PM528S-150-RC in existing designs?

A: Yes. The SRR5028-150Y meets all electrical and mechanical specifications required for direct substitution. Inductance value, tolerance, DC resistance, core material, shielding, physical dimensions, and operating temperature range are identical. The substitute part's higher current rating and saturation current provide equal or improved performance margin.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both components share identical physical dimensions (5.80mm x 5.80mm footprint) and maximum seated height (3.00mm). No PCB layout modifications are required for substitution.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the PM528S-150-RC and SRR5028-150Y are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance requirements are equivalent.

Q: What is the difference between the PM528S and SRR5028 series?

A: Both are Bourns Inc. shielded drum core wirewound inductors with identical electrical performance at the 15 µH rating. The series designation reflects different product lines within the manufacturer's portfolio. Electrical and mechanical compatibility is maintained across both series for this specific value and rating combination.

Q: Is the higher current rating of the SRR5028-150Y a concern for circuit compatibility?

A: No. A higher current rating indicates the substitute part can handle equal or greater current without saturation. This provides additional design margin and does not create compatibility issues in circuits designed for the original 1.3 A specification.
