SC5022F-100 Equivalent & Substitute Parts

Part Overview

The SC5022F-100 is a 10 µH unshielded wirewound inductor manufactured by Signal Transformer, rated for 5.2 A continuous current with a maximum DC resistance of 31 mOhm. This surface mount component operates across the temperature range of -40°C to 125°C and is specified for 100 kHz inductance testing. The part is Active status and ROHS3 compliant, making it suitable for modern electronic applications requiring fixed inductance in compact form factors.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while meeting mechanical and environmental requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the SC5022F-100 is determined by the following critical parameters:

• Inductance Value: Must be 10 µH within ±20% tolerance
• Current Rating: Must support minimum 5.2 A continuous operation
• Saturation Current: Must meet or exceed 10 A specification
• DC Resistance: Must not exceed 31 mOhm maximum
• Operating Temperature: Must encompass or exceed -40°C to 125°C range
• Mounting Type: Must be Surface Mount compatible
• Shielding Configuration: Must be Unshielded
• Regulatory Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The B82479A1103M000 qualifies as a substitute based on matching inductance value, saturation current, shielding type, mounting configuration, and regulatory compliance. Variations in current rating, DC resistance, and temperature range are within acceptable engineering tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the SC5022F-100 and B82479A1103M000 maintain Active product status and full ROHS3 compliance with MSL 1 rating, confirming suitability for current manufacturing environments. The B82479A1103M000 provides an extended operating temperature range (-55°C to 150°C versus -40°C to 125°C), offering broader environmental coverage. The substitute part's DC resistance specification of 32 mOhm remains within acceptable tolerance relative to the 31 mOhm maximum of the primary part. Selection between these parts should be based on application-specific current requirements and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the B82479A1103M000 be used in place of SC5022F-100 in all applications?

A: The B82479A1103M000 is electrically equivalent for inductance and saturation current specifications. However, the lower continuous current rating of 4.3 A versus 5.2 A requires verification that application current demands do not exceed the substitute part's rating. The extended temperature range of the substitute provides additional operational margin.

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

A: The ±20% tolerance indicates that actual inductance values may range from 8 µH to 12 µH. Both the main part and substitute share this tolerance specification, ensuring consistent circuit behavior within this defined window.

Q: Are there mechanical compatibility concerns between these parts?

A: Both parts are surface mount components with nonstandard package dimensions. The SC5022F-100 measures 0.750" L × 0.620" W × 0.280" H, while the B82479A1103M000 measures 0.730" L × 0.600" W × 0.280" H. Slight dimensional differences require PCB layout verification to confirm footprint compatibility.

Q: How do the core materials differ between these inductors?

A: The SC5022F-100 uses a standard wirewound construction, while the B82479A1103M000 employs a drum core wirewound design with ferrite material. Both maintain unshielded configuration and equivalent inductance performance at 100 kHz test frequency.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for both, indicating no special moisture protection requirements during storage or handling.
