Engineering Selection Recommendations

2474-19L Selection: The 2474-19L is suitable for applications where RoHS non-compliance is acceptable or not required. This part is active in production with 715 pieces available in stock.

2474R-19L Selection: The 2474R-19L is the preferred substitute when ROHS3 compliance is required. This variant maintains all electrical and mechanical specifications identical to the 2474-19L while meeting RoHS3 regulatory requirements. The 2474R-19L has higher inventory availability with 3,068 pieces in stock. Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99).

Selection between these parts should be based on regulatory compliance requirements for the end application. All other electrical and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 2474R-19L replace the 2474-19L in existing designs?

A: Yes. The 2474R-19L is electrically and mechanically equivalent to the 2474-19L. All critical parameters including inductance, current rating, DC resistance, core material, shielding, temperature range, and physical dimensions are identical. The primary difference is RoHS3 compliance status.

Q: What is the difference between the 2474-19L and 2474R-19L?

A: The 2474-19L is RoHS non-compliant, while the 2474R-19L is ROHS3 compliant. All electrical specifications and physical dimensions are identical between the two parts.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts are through-hole axial inductors with identical pinout, footprint, and electrical performance. Direct substitution is possible without circuit modifications.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. If ROHS3 compliance is required, use the 2474R-19L. If RoHS compliance is not a design requirement, either part is suitable. The 2474R-19L has higher inventory availability.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.240" diameter × 0.740" length (6.10 mm × 18.80 mm), ensuring identical PCB footprint and mounting compatibility.

Q: What is the saturation current specification?

A: Both the 2474-19L and 2474R-19L have a saturation current (Isat) of 1.1 A, which is lower than the rated current of 2.17 A. This parameter defines the current level at which the inductor begins to saturate.

Q: Are export restrictions the same for both parts?

A: Yes. Both parts are classified as EAR99 under ECCN and share the same HTSUS code (8504.50.4000), indicating identical export control treatment.
