SC5022C-101 Equivalent & Substitute Parts

Part Overview

The SC5022C-101 is a 100 µH shielded surface mount inductor manufactured by Signal Transformer, rated for 1.8 A continuous current with a maximum DC resistance of 207mOhm. This component is designed for applications requiring electromagnetic shielding to minimize coupling effects in adjacent circuits. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications across the -40°C to 125°C operating temperature range.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit relaxation of specific electrical or mechanical parameters while maintaining core functional performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC5022C-101 is determined by strict alignment with the following critical parameters:

• Inductance Value: 100 µH ±20% tolerance
• Current Rating: Minimum 1.8 A continuous
• Current Saturation (Isat): Minimum 2.4 A
• DC Resistance: Maximum 207mOhm
• Mounting Type: Surface Mount
• Operating Temperature: Minimum range of -40°C to 125°C
• Compliance: RoHS3 and REACH requirements

The B82479A1104M000 qualifies as a substitute based on matching inductance, current rating, saturation current, and compliance certifications. However, this substitute exhibits lower DC resistance (190mOhm maximum) and extended operating temperature range (-55°C to 150°C), representing improved electrical performance characteristics. The primary distinction is the absence of shielding in the substitute part, which may affect electromagnetic coupling behavior in noise-sensitive applications.

Parameter Comparison

Engineering Selection Recommendations

The B82479A1104M000 is qualified as a direct substitute for the SC5022C-101 based on matching inductance value, current rating, saturation current, and compliance certifications. Both components maintain Active product status with ROHS3 compliance and unlimited moisture sensitivity rating.

Selection between these components should account for the following engineering considerations:

SC5022C-101 (Primary): Retain this component when electromagnetic shielding is a circuit requirement or when design specifications explicitly mandate shielded inductor construction to prevent coupling into adjacent signal paths.

B82479A1104M000 (Substitute): This component is suitable when shielding is not a functional requirement and when the improved saturation current (3.0 A versus 2.4 A) and lower DC resistance (190mOhm versus 207mOhm) provide design margin benefits. The extended operating temperature range (-55°C to 150°C) accommodates applications with broader thermal requirements.

Both components are surface mount devices with similar physical dimensions and are suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the B82479A1104M000 replace the SC5022C-101 in all applications?

A: The B82479A1104M000 qualifies as a substitute when electromagnetic shielding is not a circuit requirement. If the design depends on shielded inductor characteristics to minimize coupling effects, the SC5022C-101 must be retained. Both components match on inductance value, current rating, and compliance certifications.

Q: What is the difference in DC resistance between these components?

A: The SC5022C-101 has a maximum DC resistance of 207mOhm, while the B82479A1104M000 has a maximum of 190mOhm. The lower resistance in the substitute part results in reduced power dissipation and improved thermal performance in the same current application.

Q: Are there physical size differences that affect PCB layout?

A: Both components have similar footprints suitable for surface mount assembly. The SC5022C-101 measures 19.04 x 15.74 mm with a maximum seated height of 7.62 mm, while the B82479A1104M000 measures 18.54 x 15.24 mm with a maximum seated height of 7.11 mm. These minor dimensional variations are typically accommodated within standard PCB design tolerances.

Q: What is the saturation current difference, and does it matter?

A: The SC5022C-101 has a saturation current of 2.4 A, while the B82479A1104M000 is rated at 3.0 A. For applications operating at or near the 1.8 A continuous rating, the higher saturation current in the substitute provides additional design margin before inductance degradation occurs.

Q: Do both components meet the same compliance requirements?

A: Yes. Both the SC5022C-101 and B82479A1104M000 are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1). Both are suitable for applications with identical regulatory requirements.

Q: What is the core material difference?

A: The SC5022C-101 uses a shielded core construction, while the B82479A1104M000 uses a ferrite drum core wirewound design. The ferrite core in the substitute provides the improved saturation current and lower DC resistance characteristics.
