Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH105-6R8 is determined by the following critical parameters:

• Inductance value must equal 6.8 µH within the ±30% tolerance specification
• Current rating must support the application's maximum continuous current requirement
• DC resistance must not exceed the maximum specified value to prevent excessive power dissipation
• Saturation current must accommodate transient current conditions
• Operating temperature range must encompass -40°C to 125°C
• Surface mount packaging and RoHS3 compliance are required for compatibility

The SRN6045-6R8Y meets these substitution criteria with equivalent inductance, matching tolerance, and compliant certifications. Differences in shielding type (semi-shielded versus fully shielded) and physical dimensions must be evaluated for specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

Both SCRH105-6R8 and SRN6045-6R8Y are Active status components with ROHS3 compliance and REACH unaffected designation, meeting regulatory requirements for industrial applications. The SRN6045-6R8Y substitute offers improved DC resistance characteristics (47.3 mOhm versus 54 mOhm) and a more compact footprint (6.00 x 6.00 mm versus 10.10 x 9.20 mm). Selection between these parts depends on application-specific constraints regarding current rating, saturation performance, shielding requirements, and available board space. The reduced current rating (2.8 A versus 3.23 A) and saturation current (3.8 A versus 6 A) of the substitute must be verified against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can SRN6045-6R8Y directly replace SCRH105-6R8 in all applications?

A: Direct replacement is possible when the application current does not exceed 2.8 A continuous and 3.8 A saturation. The semi-shielded construction of SRN6045-6R8Y may introduce different electromagnetic coupling characteristics compared to the fully shielded SCRH105-6R8, requiring evaluation in noise-sensitive circuits.

Q: What are the key differences between these inductors?

A: The primary differences are current rating (3.23 A versus 2.8 A), saturation current (6 A versus 3.8 A), shielding type (fully shielded versus semi-shielded), physical dimensions (10.10 x 9.20 mm versus 6.00 x 6.00 mm), and height (6.00 mm versus 4.50 mm). Inductance value, tolerance, and operating temperature range are identical.

Q: Does the smaller package size of SRN6045-6R8Y affect performance?

A: The SRN6045-6R8Y achieves equivalent inductance and superior DC resistance in a smaller package through different core and winding design. Physical size reduction does not degrade electrical performance within specified parameters but may alter thermal characteristics and electromagnetic field distribution.

Q: Are both parts suitable for high-frequency applications?

A: Both components are tested at 100 kHz inductance frequency. The SRN6045-6R8Y provides additional frequency data with self-resonant frequency of 20 MHz and Q factor of 15 at 7.96 MHz, indicating suitability for higher frequency operation within these specifications.

Q: What compliance certifications apply to both parts?

A: Both SCRH105-6R8 and SRN6045-6R8Y are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for both components.
