Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPD62R-153M is determined by the following critical parameters:

• Inductance value must be 15 µH
• Core material must be ferrite with shielding
• Mounting type must be surface mount
• Current rating must meet or exceed 1.2 A
• DC resistance must not exceed 300 mOhm
• RoHS3 compliance required
• Operating temperature range must encompass the application requirements

The SRR5028-150Y from Bourns Inc. qualifies as a substitute based on matching inductance, core type, shielding, and mounting configuration. The substitute exhibits improved DC resistance performance (100 mOhm max versus 300 mOhm max) and higher current rating (1.37 A versus 1.2 A), making it suitable for applications requiring the SPD62R-153M specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SPD62R-153M and SRR5028-150Y are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on the specific application requirements:

The SPD62R-153M provides a wider operating temperature range (-55°C to 125°C) and tighter inductance tolerance (±20%), making it suitable for applications requiring extended low-temperature performance or strict inductance specifications.

The SRR5028-150Y offers superior DC resistance characteristics (100 mOhm max) and higher current rating (1.37 A), providing advantages in applications where power dissipation and thermal management are critical considerations. The narrower operating temperature range (-40°C to 125°C) is acceptable for standard industrial and commercial applications.

Both components are packaged in Tape & Reel format and maintain identical mechanical form factors with nonstandard package dimensions.

Frequently Asked Questions (FAQ)

Q: Can the SRR5028-150Y directly replace the SPD62R-153M in all applications?

A: The SRR5028-150Y is electrically compatible for applications operating above -40°C. Applications requiring operation below -40°C must use the SPD62R-153M due to its extended temperature range specification.

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

A: The SRR5028-150Y exhibits lower DC resistance (100 mOhm max versus 300 mOhm max), resulting in reduced power dissipation and heat generation. This characteristic is beneficial in high-current or thermally constrained applications.

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

A: Yes, both the SPD62R-153M and SRR5028-150Y are supplied in Tape & Reel packaging suitable for automated assembly processes.

Q: How do the inductance tolerances affect circuit design?

A: The SPD62R-153M specifies ±20% tolerance while the SRR5028-150Y specifies ±30% tolerance. Applications with tight inductance requirements should account for these tolerance ranges during circuit design and validation.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
