Substitute Part Grouping Explanation

The B82479A1223M000 qualifies as a substitute for the SC5022F-220 based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Inductance value: 22 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• DC resistance: 47 mOhm maximum
• Saturation current: 7 A
• Shielding classification: Unshielded
• Mounting type: Surface Mount
• RoHS3 compliance certification
• Moisture sensitivity level: MSL 1 (Unlimited)

Acceptable Variance:

• Current rating: 4.6 A (substitute) versus 3.9 A (main part). The substitute operates at reduced continuous current capacity but maintains equivalent saturation performance.
• Operating temperature range: -55°C to 150°C (substitute) provides extended low-temperature and high-temperature coverage compared to -40°C to 125°C (main part).
• Physical dimensions: 0.730" L × 0.600" W × 0.280" H (substitute) versus 0.750" L × 0.620" W × 0.280" H (main part). Height is identical; length and width differences are within typical PCB layout tolerances for nonstandard packages.

Parameter Comparison

Engineering Selection Recommendations

SC5022F-220 Selection Criteria:

• Primary choice when continuous current demand reaches 3.9 A
• Preferred for applications constrained to -40°C to 125°C operating window
• Suitable for designs where exact physical footprint dimensions are critical

B82479A1223M000 Selection Criteria:

• Acceptable substitute when continuous current requirement does not exceed 4.6 A
• Preferred for applications requiring extended temperature operation (-55°C to 150°C)
• Suitable for designs tolerating minor PCB layout adjustments due to dimension variance
• Ferrite drum core construction provides alternative core material technology

Both parts maintain Active product status, ROHS3 compliance, and identical saturation current performance. Selection between these components depends on application-specific current requirements and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can B82479A1223M000 replace SC5022F-220 in all applications?

A: The B82479A1223M000 is electrically compatible when the application current requirement does not exceed 4.6 A continuous. If your circuit demands the full 3.9 A rating of the SC5022F-220, the substitute cannot be used. Both parts deliver identical inductance, tolerance, DC resistance, and saturation current specifications.

Q: What is the significance of the current rating difference?

A: The SC5022F-220 supports 3.9 A continuous current, while the B82479A1223M000 supports 4.6 A. Both reach 7 A saturation current. Applications operating below 4.6 A experience no functional difference. Applications requiring 4.6 A to 3.9 A continuous current must use the SC5022F-220.

Q: Are the physical dimension differences problematic?

A: The B82479A1223M000 measures 0.730" L × 0.600" W versus the SC5022F-220 at 0.750" L × 0.620" W. Height is identical at 0.280". These minor differences (0.020" length, 0.020" width) typically accommodate standard PCB layout tolerances for nonstandard packages. Verify footprint clearance in your specific design.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SC5022F-220 and B82479A1223M000 carry ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status. Regulatory requirements are equivalent.

Q: What core material difference exists between these inductors?

A: The SC5022F-220 uses wirewound construction with unspecified core material. The B82479A1223M000 uses ferrite drum core wirewound construction. Both deliver identical electrical performance at the specified test frequency of 100 kHz.

Q: Can I use B82479A1223M000 in high-temperature applications?

A: Yes. The B82479A1223M000 operates to 150°C maximum, exceeding the SC5022F-220 specification of 125°C. For applications requiring operation above 125°C, the B82479A1223M000 provides extended thermal capability.
