Engineering Selection Recommendations

Primary Component: UP0.4SC-1R0-R

The UP0.4SC-1R0-R maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating. Selection of this component is appropriate when Eaton supply chain continuity and existing qualification documentation are required.

Substitute Component: SRR6603-1R0ML

The SRR6603-1R0ML from Bourns Inc. is qualified as a direct substitute based on identical electrical performance specifications and compatible mechanical dimensions. This component offers extended operating temperature range (-55°C to 125°C versus -40°C to 125°C), ROHS3 compliance certification, and REACH unaffected status. The Bourns component is suitable for applications where enhanced temperature performance or alternative supply sourcing is required. Physical dimensions remain within acceptable tolerance for PCB layout compatibility.

Both components are classified as Active products with unlimited moisture sensitivity rating and identical packaging format (Tape & Reel).

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for substitution eligibility?

A: The inductance value (1 µH ±20%), current rating (3 A), DC resistance (40 mOhm maximum), Q factor at 200 kHz (30), self resonant frequency (250 MHz), and shielding configuration must all match the original specification. These parameters define the functional performance envelope of the component within the circuit.

Q: Are the physical dimensions of the substitute part compatible with the original PCB layout?

A: Yes. The SRR6603-1R0ML maintains identical length (6.60 mm) and width (4.40 mm versus 4.45 mm original), with seated height of 3.00 mm versus 2.92 mm original. These dimensional variations remain within standard PCB design tolerances for surface mount component placement.

Q: What is the difference between the core materials of these two inductors?

A: The UP0.4SC-1R0-R uses a standard wirewound core configuration, while the SRR6603-1R0ML employs a drum core ferrite construction. Both achieve identical electrical specifications at the specified test frequency (100 kHz) and operating conditions.

Q: Does the substitute part have different temperature operating limits?

A: The SRR6603-1R0ML operates across -55°C to 125°C, extending the lower temperature limit by 15°C compared to the UP0.4SC-1R0-R (-40°C to 125°C). Both components meet or exceed the original specification's upper temperature limit of 125°C.

Q: Are both components RoHS compliant?

A: Yes. The UP0.4SC-1R0-R carries RoHS Compliant certification, while the SRR6603-1R0ML carries ROHS3 Compliant certification. Both satisfy RoHS directive requirements for restricted substance elimination.

Q: What is the saturation current specification for the substitute part?

A: The SRR6603-1R0ML has a saturation current (Isat) of 1.4 A. This parameter was not specified for the original UP0.4SC-1R0-R component in the provided documentation.

Q: Can these components be used interchangeably in existing designs?

A: Yes, provided the circuit design does not depend on specifications unique to either component. The identical electrical performance at the specified test frequency (100 kHz) and operating temperature range overlap (-40°C to 125°C) support direct substitution for standard applications.
