Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC3326F-6R8 is determined by the following critical parameters:

• Inductance value of 6.8 µH within ±20% tolerance
• Surface mount packaging configuration
• Unshielded construction
• Wirewound or equivalent core type
• ROHS3 compliance status
• Operating temperature range compatibility

The B82476B1682M100 qualifies as a substitute based on matching inductance (6.8 µH), tolerance (±20%), unshielded construction, surface mount configuration, and ROHS3 compliance. Variations in current rating, DC resistance, and physical dimensions are secondary considerations when primary electrical characteristics align.

Parameter Comparison

Engineering Selection Recommendations

Both the SC3326F-6R8 and B82476B1682M100 maintain Active product status and ROHS3 compliance. The B82476B1682M100 provides an extended operating temperature range (-55°C to 150°C versus -40°C to 125°C) and lower DC resistance (21 mOhm versus 23 mOhm). The primary design consideration is current rating: the SC3326F-6R8 supports 6 A continuous current, while the B82476B1682M100 is rated for 4.8 A. Selection between these parts depends on circuit current requirements and thermal operating conditions. The B82476B1682M100 includes AEC-Q200 automotive qualification, applicable for automotive-grade applications.

Frequently Asked Questions (FAQ)

Q: Can the B82476B1682M100 replace the SC3326F-6R8 in all applications?

A: Substitution is valid when circuit current requirements do not exceed 4.8 A. The SC3326F-6R8 is required for applications demanding the full 6 A rating.

Q: What is the significance of the ±20% inductance tolerance?

A: Both parts share ±20% tolerance, meaning actual inductance values may range from 5.44 µH to 8.16 µH. This tolerance band is identical for both components.

Q: Are there physical mounting differences between these parts?

A: Yes. The B82476B1682M100 is physically smaller (0.510" x 0.370" x 0.200" max height) compared to the SC3326F-6R8 (0.530" x 0.390" x 0.315" max height). PCB layout and clearance requirements must accommodate these dimensional differences.

Q: Does the lower DC resistance of the B82476B1682M100 affect circuit performance?

A: Lower DC resistance (21 mOhm versus 23 mOhm) reduces resistive losses. This difference is minor and typically negligible in most circuit applications.

Q: What does AEC-Q200 qualification mean for the B82476B1682M100?

A: AEC-Q200 indicates automotive-grade reliability testing and qualification. This certification is relevant only for automotive applications; it provides no functional advantage in non-automotive circuits.
