Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCC5D23-391 is determined by strict alignment of the following parameters:

• Inductance value: 390 µH with ±20% tolerance
• Current rating: minimum 240 mA continuous capability
• DC resistance: maximum 4.06Ohm to ensure equivalent power dissipation characteristics
• Shielding: shielded construction required
• Mounting: surface mount configuration
• Operating temperature: -40°C ~ 125°C range
• Package footprint: 6.00mm x 6.00mm base dimensions with height compatibility

The PA4300.394NLT meets these substitution criteria as an active component with identical inductance specification, compatible current rating, superior DC resistance performance, and matching environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

The PA4300.394NLT from Pulse Electronics is the qualified substitute for the obsolete SCC5D23-391. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility.

The substitute component exhibits superior DC resistance performance at 2.4Ohm maximum compared to the original 4.06Ohm specification, resulting in reduced power dissipation and improved thermal characteristics. The current rating differential (210 mA versus 240 mA) requires application-level verification to confirm the substitute operates within the circuit's maximum current demand.

Physical dimensions are compatible within standard PCB assembly tolerances. The 0.50mm height increase of the substitute (3.00mm versus 2.50mm) must be evaluated against available PCB clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can PA4300.394NLT directly replace SCC5D23-391 in all applications?

A: Direct substitution is possible when the application current requirement does not exceed 210 mA. The substitute's lower DC resistance provides equivalent or improved performance in power dissipation. PCB clearance must accommodate the 3.00mm maximum seated height.

Q: What is the significance of the current rating difference?

A: The SCC5D23-391 is rated for 240 mA continuous current, while PA4300.394NLT is rated for 210 mA. Applications operating above 210 mA require confirmation that the substitute's saturation characteristics remain acceptable at the intended operating current.

Q: Are there mechanical compatibility concerns?

A: The footprint dimensions (6.10mm x 6.10mm versus 6.00mm x 6.00mm) are compatible within standard PCB assembly tolerances. The height difference of 0.50mm must be verified against component clearance requirements in the target assembly.

Q: Do both components meet the same regulatory standards?

A: Yes. Both SCC5D23-391 and PA4300.394NLT are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent regulatory and environmental performance.

Q: Why is the substitute component preferred despite lower current rating?

A: The PA4300.394NLT is an active production component from Pulse Electronics, ensuring long-term availability and supply chain continuity. The obsolete status of SCC5D23-391 makes the substitute necessary for new designs and ongoing production support.
