SC5022F-221 Equivalent & Substitute Parts

Part Overview

The SC5022F-221 is a 220 µH unshielded wirewound inductor manufactured by Signal Transformer, designed for surface mount applications. This component is rated for 1.2 A continuous current with a maximum DC resistance of 380 mOhm and operates across the temperature range of -40°C to 125°C. The part is currently active in production and ROHS3 compliant, making it suitable for modern electronic assemblies requiring fixed inductance filtering, energy storage, or signal conditioning in power management and RF circuits.

Equivalent parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required for manufacturing optimization while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the SC5022F-221 is permissible with the B82479A1224M000 based on the following electrical and mechanical equivalence criteria:

Electrical Parameters (Matched):

• Inductance value: 220 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Current rating: 1.2 A continuous
• Saturation current: 2.4 A
• DC resistance: 380 mOhm maximum
• Shielding configuration: Unshielded

Mechanical Parameters (Compatible):

• Mounting type: Surface mount
• Package classification: Nonstandard
• Height seated maximum: 0.280" (7.11 mm)
• Footprint dimensions: Within acceptable tolerance variance

Compliance & Environmental (Equivalent):

• RoHS3 compliance status
• Moisture sensitivity level: 1 (Unlimited)
• REACH unaffected classification

The substitute part operates across an extended temperature range (-55°C to 150°C) compared to the original part, providing broader environmental compatibility without compromising the specified operating window.

Parameter Comparison

Engineering Selection Recommendations

Both the SC5022F-221 and B82479A1224M000 maintain active product status and full ROHS3 compliance. The B82479A1224M000 is manufactured by EPCOS - TDK Electronics, a primary inductor supplier with established quality and reliability standards. The extended operating temperature range of the substitute part (-55°C to 150°C versus -40°C to 125°C) provides additional thermal margin for applications subject to extreme environmental conditions.

Selection between these parts should be based on availability, lead time, and supply chain requirements. Both components satisfy identical electrical specifications and mechanical mounting requirements for surface mount PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can the B82479A1224M000 be used as a direct replacement for the SC5022F-221?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: 220 µH inductance, 1.2 A current rating, 380 mOhm DC resistance, and identical saturation current. Both are unshielded surface mount components with matching height and footprint compatibility.

Q: What is the difference in core material between these inductors?

A: The SC5022F-221 uses a wirewound core type, while the B82479A1224M000 uses a drum core wirewound configuration with ferrite material. Both achieve identical inductance and DC resistance specifications at the test frequency of 100 kHz.

Q: Are there any temperature range considerations for substitution?

A: The B82479A1224M000 operates across -55°C to 150°C, which exceeds the SC5022F-221 operating range of -40°C to 125°C. For applications within the original part's temperature specification, both components are suitable. For extended temperature applications, the substitute part provides additional thermal capability.

Q: Do both parts have the same moisture sensitivity classification?

A: Yes. Both the SC5022F-221 and B82479A1224M000 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Are there any PCB layout or assembly differences between these parts?

A: No. Both components share identical mounting type (surface mount), maximum seated height (0.280"), and nonstandard package classification. PCB footprint design and assembly processes remain unchanged during substitution.
