Key Parameters

Substitute Part Grouping Explanation

The CDR6D28MNNP-5R5NC from Sumida America Components Inc. qualifies as a direct substitute based on the following critical parameters:

Matching Parameters:

• Inductance: 5.5 µH (identical)
• Shielding: Shielded (identical)
• Mounting Type: Surface Mount (identical)
• Inductance Test Frequency: 100 kHz (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Enhanced Performance Characteristics: The substitute part provides improved electrical performance within the same physical and functional envelope, with higher current rating (2.2 A vs. 1.8 A) and lower DC resistance (63.8 mOhm vs. 96 mOhm), making it suitable for applications requiring the original part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The CDR6D28MNNP-5R5NC is the qualified substitute for the obsolete SCRH62B-5R5. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental consistency. The substitute part is currently in active production status with confirmed inventory availability, addressing the obsolescence of the original component.

The substitute exhibits superior electrical performance with increased current rating and reduced DC resistance, making it suitable for applications originally designed around the SCRH62B-5R5 specifications. The operating temperature range of the substitute (-40°C to 105°C) covers the majority of industrial applications, with the exception of designs requiring operation above 105°C, which would necessitate alternative component selection.

Physical dimensions remain compatible within standard PCB assembly tolerances, with the substitute featuring a slightly reduced seated height (3.00mm vs. 3.20mm), which may provide marginal benefits in space-constrained layouts.

Frequently Asked Questions (FAQ)

Q: Can the CDR6D28MNNP-5R5NC be used as a direct replacement for the SCRH62B-5R5?

A: Yes. Both components share identical inductance values (5.5 µH), shielding configuration, surface mount packaging, and compliance certifications. The substitute meets or exceeds the electrical specifications of the original part.

Q: What are the key differences between these two inductors?

A: The primary differences are current rating (1.8 A vs. 2.2 A), DC resistance (96 mOhm vs. 63.8 mOhm), saturation current (1.4 A vs. 3.15 A), and maximum operating temperature (125°C vs. 105°C). The substitute provides improved performance in current handling and efficiency.

Q: Are there any packaging or mounting compatibility concerns?

A: Both components are surface mount inductors with compatible footprints. The substitute features a slightly smaller seated height (3.00mm vs. 3.20mm), which is advantageous for compact designs and does not create compatibility issues.

Q: Does the substitute meet the same regulatory requirements?

A: Yes. Both the SCRH62B-5R5 and CDR6D28MNNP-5R5NC are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring equivalent regulatory and environmental performance.

Q: What is the inductance tolerance difference, and does it affect substitution?

A: The original part specifies -20%, +40% tolerance, while the substitute offers ±25% tolerance. The substitute's tighter tolerance range provides improved consistency and may benefit applications with strict inductance specifications.

Q: Is the substitute suitable for high-temperature applications above 105°C?

A: The substitute is rated to 105°C maximum. Applications requiring operation above 105°C would need alternative component selection, as the original part's 125°C rating would not be matched.
