SPD62R-154M Equivalent & Substitute Parts

Part Overview

The SPD62R-154M is a 150 µH shielded drum core wirewound inductor manufactured by API Delevan Inc., rated for 370 mA continuous current with a maximum DC resistance of 1.8Ohm. This surface mount component is designed for applications requiring fixed inductance in compact form factors with ferrite core shielding. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent inductance values, compatible current ratings, and matching shielding characteristics are required due to inventory constraints, lead time considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

The SRR5028-151Y qualifies as a substitute for the SPD62R-154M based on the following critical parameters:

Inductance equivalence: Both parts specify 150 µH nominal inductance, meeting the primary functional requirement.

Current handling capability: The SRR5028-151Y is rated for 330 mA continuous current with 350 mA saturation current, which satisfies applications where the SPD62R-154M's 370 mA rating is not fully utilized or where design margins permit operation at the lower rating.

Shielding configuration: Both inductors feature shielded drum core construction with ferrite material, maintaining electromagnetic isolation in the same manner.

Surface mount compatibility: Both components use surface mount packaging with nonstandard case dimensions, enabling direct PCB integration.

Compliance alignment: Both parts carry RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating, ensuring regulatory compatibility.

Operating temperature overlap: The SRR5028-151Y operates across -40°C ~ 125°C, which encompasses the primary operating range of the SPD62R-154M above -40°C.

Parameter Comparison

Engineering Selection Recommendations

Both the SPD62R-154M and SRR5028-151Y maintain Active product status with equivalent regulatory compliance profiles. Selection between these parts should be based on the following provided specifications:

Current requirement: If the application requires the full 370 mA rating of the SPD62R-154M, this part is the primary choice. The SRR5028-151Y is suitable for applications where 330 mA continuous current is sufficient.

DC resistance consideration: The SPD62R-154M exhibits higher DC resistance at 1.8Ohm maximum, while the SRR5028-151Y provides lower resistance at 900mOhm maximum. Applications sensitive to resistive losses should account for this difference.

Temperature range: The SPD62R-154M supports operation down to -55°C, whereas the SRR5028-151Y operates from -40°C minimum. Selection depends on whether extended low-temperature performance is required.

Physical dimensions: The SRR5028-151Y occupies a smaller footprint (5.80mm x 5.80mm versus 6.60mm x 6.20mm), which may be advantageous in space-constrained designs. Both maintain identical seated height of 3.00mm.

Inductance tolerance: The SPD62R-154M specifies ±20% tolerance compared to ±30% for the SRR5028-151Y. Applications requiring tighter inductance accuracy favor the SPD62R-154M.

Frequently Asked Questions (FAQ)

Q: Can the SRR5028-151Y directly replace the SPD62R-154M in all applications?

A: Direct replacement is possible when the application current requirement does not exceed 330 mA and the operating temperature remains above -40°C. The lower DC resistance of the SRR5028-151Y may provide performance benefits in low-loss applications. Verify that the ±30% inductance tolerance of the SRR5028-151Y is acceptable for your circuit design.

Q: What are the key differences in electrical performance between these inductors?

A: The primary electrical differences are current rating (370 mA versus 330 mA), DC resistance (1.8Ohm versus 900mOhm), and inductance tolerance (±20% versus ±30%). Both parts maintain identical 150 µH inductance and ferrite shielded construction.

Q: Are there physical compatibility concerns when substituting these parts?

A: Both inductors feature identical seated height of 3.00mm and nonstandard surface mount packages. The SRR5028-151Y has a smaller footprint (5.80mm x 5.80mm) compared to the SPD62R-154M (6.60mm x 6.20mm). PCB layout verification is recommended to confirm the smaller footprint does not create routing conflicts.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the SPD62R-154M and SRR5028-151Y carry RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), ensuring equivalent regulatory alignment.

Q: Which part should be selected for extended low-temperature applications?

A: The SPD62R-154M is required for applications operating below -40°C, as it supports temperatures down to -55°C. The SRR5028-151Y minimum operating temperature is -40°C.
