SC5022F-101 Equivalent & Substitute Parts

Part Overview

The SC5022F-101 is a 100 µH unshielded wirewound surface mount inductor manufactured by Signal Transformer. Rated for 1.95 A continuous current with a maximum DC resistance of 190mOhm, this component is designed for applications requiring fixed inductance in compact form factors. The part is Active status and ROHS3 compliant, suitable for industrial and commercial electronic assemblies operating across -40°C to 125°C. Substitute parts are identified to provide equivalent electrical performance and mechanical compatibility for procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC5022F-101 is determined by strict equivalence across the following critical parameters:

Inductance value must match at 100 µH with identical ±20% tolerance. Current rating of the substitute must meet or exceed 1.95 A continuous operation. DC resistance must not exceed 190mOhm maximum to ensure equivalent power dissipation characteristics. Saturation current (Isat) must be at minimum 3 A to maintain performance margin. Shielding configuration must remain unshielded to preserve electromagnetic coupling behavior in the target application. Surface mount packaging and nonstandard case dimensions are required for mechanical fit. Operating temperature range of the substitute must encompass or exceed the -40°C to 125°C specification. RoHS3 compliance and MSL 1 rating are mandatory for regulatory and manufacturing process compatibility.

The B82479A1104M000 from EPCOS - TDK Electronics meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The B82479A1104M000 is designated as the manufacturer-recommended substitute for the SC5022F-101. Both components are Active status products with ROHS3 compliance and MSL 1 rating, ensuring regulatory alignment and manufacturing process compatibility.

The primary consideration for selection is the current rating differential: the SC5022F-101 is rated at 1.95 A while the B82479A1104M000 is rated at 1.8 A. Applications operating at or near the 1.95 A specification require evaluation of actual circuit current demand to confirm the substitute's adequacy. The B82479A1104M000 provides extended operating temperature range (-55 to 150°C versus -40 to 125°C), which may offer thermal margin in demanding environments.

Dimensional differences are minor: the substitute is 0.5mm shorter in length and 0.5mm narrower in width, with identical seated height. PCB layout verification is necessary to confirm mechanical fit. Packaging format differs between the main part (Tape & Reel) and substitute (Cut Tape & Digi-Reel®); procurement and assembly processes must accommodate this distinction.

Frequently Asked Questions (FAQ)

Q: Can the B82479A1104M000 directly replace the SC5022F-101 in all applications?

A: Direct replacement is possible for applications where circuit current does not exceed 1.8 A. Applications designed for the full 1.95 A rating of the SC5022F-101 require current margin analysis before substitution.

Q: What is the significance of the drum core construction in the B82479A1104M000?

A: The drum core, wirewound construction with ferrite material in the B82479A1104M000 provides equivalent inductance and DC resistance performance to the SC5022F-101. The ferrite core material is specified for the substitute; the main part core material is not specified in available documentation.

Q: Are the dimensional differences between these parts critical?

A: The substitute is 0.5mm shorter in length and width with identical height. PCB layout must be verified to confirm the smaller footprint does not create mechanical interference or spacing violations in the target assembly.

Q: Do packaging format differences affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) affects procurement and assembly logistics only, not electrical or mechanical performance of the component itself.

Q: Is the extended temperature range of the B82479A1104M000 a performance advantage?

A: The B82479A1104M000 operates from -55 to 150°C compared to -40 to 125°C for the SC5022F-101. This extended range provides thermal margin but does not alter performance within the SC5022F-101 specification window.

Q: What compliance certifications apply to both parts?

A: Both the SC5022F-101 and B82479A1104M000 are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). Both carry EAR99 export classification.
