Substitute Part Grouping Explanation

Substitution of the SPD62R-393M with the SRR5028-390Y is permissible based on the following alignment of critical parameters:

• Inductance Match: Both parts specify 39 µH inductance, meeting the primary functional requirement
• Core Type Compatibility: Both utilize ferrite drum core wirewound construction with shielding
• Mounting Compatibility: Both are surface mount components with identical height (0.118" / 3.00 mm maximum seated height)
• Packaging Format: Both are supplied in Tape & Reel format
• Compliance Alignment: Both are ROHS3 compliant and REACH unaffected
• Temperature Range: The substitute operates within -40°C to 125°C, which overlaps the main part's -55°C to 125°C range

Differences in current rating (860 mA vs. 780 mA), DC resistance (210 mOhm vs. 700 mOhm), and inductance tolerance (±30% vs. ±20%) must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the SPD62R-393M and SRR5028-390Y maintain Active product status and are ROHS3 compliant with identical moisture sensitivity ratings. The SRR5028-390Y offers superior DC resistance performance (210 mOhm vs. 700 mOhm) and higher current rating capability (860 mA vs. 780 mA), which may provide operational advantages in applications sensitive to resistive losses. The SPD62R-393M maintains tighter inductance tolerance (±20% vs. ±30%) and extended low-temperature operation to -55°C. Selection between these parts depends on whether the application prioritizes lower DC resistance and higher current capacity or tighter inductance tolerance and extended temperature range.

Frequently Asked Questions (FAQ)

Q: Can the SRR5028-390Y directly replace the SPD62R-393M in my circuit?

A: Direct replacement is possible if your circuit design accommodates the parameter differences. The substitute has lower DC resistance (210 mOhm vs. 700 mOhm), higher current rating (860 mA vs. 780 mA), and wider inductance tolerance (±30% vs. ±20%). Verify that these differences do not adversely affect circuit performance.

Q: What are the physical compatibility considerations?

A: Both parts have identical maximum seated height (3.00 mm) and are surface mount components. However, the SPD62R-393M measures 6.60 mm × 6.20 mm while the SRR5028-390Y measures 5.80 mm × 5.80 mm. PCB footprint and layout spacing must accommodate the dimensional differences.

Q: Are there temperature range limitations with the substitute?

A: The SRR5028-390Y operates from -40°C to 125°C, compared to the SPD62R-393M's -55°C to 125°C. If your application requires operation below -40°C, the substitute is not suitable.

Q: How do the inductance tolerances affect circuit design?

A: The SPD62R-393M specifies ±20% tolerance while the SRR5028-390Y specifies ±30%. Applications requiring tighter inductance accuracy should account for the wider tolerance of the substitute part in circuit simulations and performance margins.

Q: Are both parts compliant with regulatory requirements?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8504.50.4000). Regulatory compliance is equivalent between the two parts.
