Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC10F-330 is determined by the following critical parameters:

• Inductance Value: 33 µH ±20% tolerance
• Current Rating: Minimum 2.4 A continuous current capability
• DC Resistance: Maximum 95 mOhm to maintain circuit performance
• Saturation Current (Isat): Minimum 1.72 A
• Mounting Type: Surface mount configuration
• Environmental Compliance: ROHS3 compliance required
• Operating Temperature: Functional across -40°C to 125°C minimum

The substitute part B82476B1333M100 meets these criteria with equivalent inductance, comparable current handling, lower DC resistance, and extended temperature range capability.

Parameter Comparison

Engineering Selection Recommendations

Both the SC10F-330 and B82476B1333M100 are active production components with ROHS3 compliance and REACH unaffected status. The B82476B1333M100 offers improved saturation current performance (2.0 A versus 1.72 A) and lower DC resistance (88 mOhm versus 95 mOhm maximum), with an extended operating temperature range of -55°C to 150°C compared to -40°C to 125°C. The B82476B1333M100 carries AEC-Q200 automotive qualification. Both components maintain identical inductance values and tolerance specifications at the 100 kHz test frequency. Selection between these parts depends on application-specific requirements for temperature extremes, saturation margin, and automotive compliance certification.

Frequently Asked Questions (FAQ)

Q: Can B82476B1333M100 directly replace SC10F-330 in all applications?

A: Both parts share identical inductance values (33 µH ±20%), unshielded configuration, and surface mount packaging. The B82476B1333M100 has lower DC resistance and higher saturation current, making it suitable for applications within the overlapping temperature range of -40°C to 125°C. Applications requiring operation below -40°C or above 125°C must evaluate the extended range of the substitute part.

Q: What is the significance of the DC resistance difference?

A: The B82476B1333M100 has a maximum DC resistance of 88 mOhm compared to 95 mOhm for the SC10F-330. Lower DC resistance reduces resistive losses in the inductor, resulting in improved efficiency and reduced heat generation in the circuit.

Q: Are there physical dimension differences between these parts?

A: The SC10F-330 measures 0.453" L x 0.382" W x 0.197" H (11.50mm x 9.70mm x 5.00mm). The B82476B1333M100 measures 0.510" L x 0.370" W x 0.200" H (12.95mm x 9.40mm x 5.08mm). PCB layout and clearance requirements must account for these dimensional variations.

Q: What does AEC-Q200 certification on the substitute part indicate?

A: AEC-Q200 is an automotive electronics qualification standard. The B82476B1333M100 meets this specification, indicating suitability for automotive applications with defined reliability and performance standards. The SC10F-330 does not carry this certification.

Q: Are both parts available in the same packaging format?

A: The SC10F-330 is supplied in standard packaging. The B82476B1333M100 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. Packaging format selection depends on assembly process requirements and order quantities.
