Physical dimensions are within acceptable tolerances for nonstandard package applications, with the B82479A1334M000 offering slightly reduced footprint dimensions. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in target markets.

Frequently Asked Questions (FAQ)

Q: Are SC5022F-331 and B82479A1334M000 electrically interchangeable?

A: Yes. Both components share identical inductance (330 µH ±20%), current rating (1 A), saturation current (1.9 A), and DC resistance (560 mOhm Max) specifications. Electrical performance in circuit applications is equivalent.

Q: What are the physical dimension differences between these parts?

A: The SC5022F-331 measures 0.750" L x 0.620" W x 0.280" H (19.04mm x 15.74mm x 7.11mm). The B82479A1334M000 measures 0.730" L x 0.600" W x 0.280" H (18.54mm x 15.24mm x 7.11mm). Height is identical; length and width differences are minimal and typically acceptable for nonstandard package PCB layouts.

Q: Does the operating temperature range difference affect substitution suitability?

A: The B82479A1334M000 operating range (-55°C ~ 150°C) exceeds the SC5022F-331 range (-40°C ~ 125°C). For applications operating within -40°C ~ 125°C, both components are suitable. For applications requiring extended temperature operation, the B82479A1334M000 provides additional thermal capability.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both SC5022F-331 and B82479A1334M000 are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for restricted substance control and chemical safety.

Q: What is the difference between wirewound and drum core wirewound construction?

A: The SC5022F-331 uses standard wirewound construction. The B82479A1334M000 uses drum core wirewound construction with ferrite core material. Both achieve identical electrical specifications at the specified test frequency (100 kHz) and current ratings.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes, provided PCB layout accommodates the minor dimensional variations. The identical height (0.280") and comparable length/width dimensions permit direct substitution in most nonstandard package applications without layout modification.
