Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCRH62B-120 is based on the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 12 µH (fixed requirement)
• Inductance test frequency: 100 kHz
• Shielding type: Shielded
• Mounting technology: Surface Mount
• Physical form factor: Nonstandard package with compatible dimensions

Secondary Compatibility Parameters:

• Current rating must meet or exceed 1.24 A
• DC resistance must not exceed 200mOhm
• Operating temperature range must cover -40°C to 125°C or be compatible with application requirements
• RoHS3 compliance required

The CDR6D28MNNP-120NC from Sumida America Components Inc. qualifies as a direct substitute based on matching inductance, shielding, mounting type, and compliance certifications, while offering improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CDR6D28MNNP-120NC is the qualified substitute for the obsolete SCRH62B-120. Selection is based on:

Electrical Compatibility: Both parts maintain 12 µH inductance at 100 kHz test frequency. The substitute provides superior electrical performance with lower DC resistance (120mOhm vs. 200mOhm) and higher current ratings (1.5 A vs. 1.24 A), ensuring reliable operation within the original design specifications.

Compliance Status: Both components meet ROHS3 requirements and carry MSL 1 moisture sensitivity classification, confirming equivalent environmental compliance for manufacturing and storage.

Product Availability: The substitute part is classified as Active with confirmed inventory (737 pcs), whereas the main part is Obsolete. This availability difference necessitates the substitution for ongoing production and new design implementations.

Thermal Consideration: The substitute operates to 105°C maximum, compared to the main part's 125°C upper limit. Applications requiring operation above 105°C require thermal analysis or alternative component selection.

Physical Form Factor: Dimensional compatibility is maintained with minor height variation (3.00mm vs. 3.20mm), suitable for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CDR6D28MNNP-120NC directly replace SCRH62B-120 in existing designs?

A: Yes, for applications operating within -40°C to 105°C. The substitute maintains identical inductance value, shielding type, and mounting technology. Verify thermal requirements if the original design specified operation above 105°C.

Q: What are the key electrical differences between these parts?

A: The substitute offers lower DC resistance (120mOhm vs. 200mOhm) and higher current rating (1.5 A vs. 1.24 A). These represent performance improvements that maintain backward compatibility with the original design envelope.

Q: Are there packaging or handling differences?

A: Both parts carry MSL 1 classification with unlimited shelf life under controlled storage. The substitute is supplied in Tape & Reel packaging. Physical dimensions are nearly identical with a 0.2mm height difference, which does not affect standard PCB assembly compatibility.

Q: Why is the main part classified as Obsolete?

A: The SCRH62B-120 is no longer in active production. The CDR6D28MNNP-120NC represents the current active equivalent from an alternative manufacturer, ensuring continued supply chain access for this inductance value and specification class.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and carry REACH Unaffected status. ECCN classification is EAR99 for both parts, confirming equivalent export control treatment.
