Substitute Part Grouping Explanation

Substitution eligibility for the SC62CB-101 is determined by the following critical parameters:

• Inductance Value: Must be 100 µH with ±20% tolerance
• Current Rating: Minimum 580 mA continuous current capability
• DC Resistance: Maximum 813 mOhm to maintain circuit performance
• Shielding: Must be shielded to prevent electromagnetic interference
• Operating Temperature: Must support -40°C to 125°C range
• Mounting Type: Surface mount configuration required
• Compliance: RoHS3 compliance and MSL 1 rating required

The B82472G4104M000 qualifies as an equivalent substitute based on matching inductance value, shielding type, surface mount configuration, temperature range, and compliance certifications. Variations in saturation current, DC resistance, and physical dimensions remain within acceptable engineering tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

The B82472G4104M000 is qualified as a direct electrical equivalent to the SC62CB-101 based on matching inductance specifications, tolerance bands, and shielding requirements. Both components maintain RoHS3 compliance and MSL 1 ratings, ensuring regulatory and environmental compatibility.

The substitute part demonstrates superior DC resistance performance (700 mOhm versus 813 mOhm maximum), reducing power dissipation in the circuit. The saturation current rating of 450 mA on the substitute exceeds the main part specification, providing additional design margin.

The primary consideration for substitution is the physical footprint increase from 6.30mm × 6.20mm to 7.30mm × 7.30mm. PCB layout verification is necessary to confirm space availability. The substitute part's extended lower operating temperature limit (-55°C versus -40°C) provides additional environmental flexibility without performance compromise.

Frequently Asked Questions (FAQ)

Q: Can the B82472G4104M000 be used in place of SC62CB-101 in existing designs?

A: Yes, provided PCB layout accommodates the larger footprint (7.30mm × 7.30mm versus 6.30mm × 6.20mm). Electrical performance is equivalent or superior across all specified parameters.

Q: What is the impact of the 20 mA lower current rating on the substitute part?

A: The B82472G4104M000 is rated for 560 mA continuous current versus 580 mA for the SC62CB-101. This 3.4% reduction must be evaluated against actual circuit current requirements. If circuit current remains below 560 mA, substitution is valid.

Q: Are there differences in DC resistance that affect circuit performance?

A: The substitute part features 700 mOhm maximum DC resistance compared to 813 mOhm for the main part. This lower resistance reduces power dissipation and heat generation, improving overall circuit efficiency.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both SC62CB-101 and B82472G4104M000 are RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings. No additional qualification is required from a regulatory standpoint.

Q: What is the significance of the different saturation current ratings?

A: The substitute part has a higher saturation current (450 mA versus 330 mA). This indicates the substitute can handle higher current levels before inductance degradation occurs, providing additional design margin in applications approaching saturation limits.

Q: How does the extended temperature range of the substitute affect compatibility?

A: The B82472G4104M000 operates from -55°C to 125°C compared to -40°C to 125°C for the SC62CB-101. The wider range provides flexibility for applications in extended temperature environments without performance degradation.
