Engineering Selection Recommendations
2474-03L Selection Criteria: The 2474-03L is suitable for applications where RoHS non-compliant components are acceptable. Current inventory availability is 909 pieces. This part maintains Active product status and is appropriate for legacy systems or applications without RoHS compliance mandates.
2474R-03L Selection Criteria: The 2474R-03L is the preferred substitute when RoHS3 compliance is required. This variant maintains identical electrical and mechanical specifications while meeting modern regulatory requirements. Current inventory availability is 2019 pieces, providing superior supply chain availability.
Selection Logic: Component selection between 2474-03L and 2474R-03L is determined by regulatory compliance requirements. Both parts deliver identical electrical performance and physical compatibility. The "R" designation in the 2474R-03L indicates RoHS3 compliance status. When regulatory compliance is not a constraint, either part functions identically. When RoHS3 compliance is mandated, the 2474R-03L is the appropriate selection.
Frequently Asked Questions (FAQ)
Q: Are the 2474-03L and 2474R-03L electrically interchangeable?
A: Yes. Both components deliver identical inductance (1.5 µH), current rating (5.67 A), saturation current (5.2 A), and DC resistance (11 mOhm Max). Electrical performance is equivalent across all specified operating conditions.
Q: What is the primary difference between these two parts?
A: The 2474R-03L is RoHS3 compliant, while the 2474-03L is RoHS non-compliant. All other electrical and mechanical specifications are identical.
