• Current rating: 490 mA continuous
• DC resistance: 1.5Ohm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Operating temperature range: -55°C to 125°C
• Mounting and package: Through-hole axial configuration
• Physical dimensions: 0.240" Dia × 0.740" L (6.10mm × 18.80mm)

The 2474R-35L maintains identical electrical performance and mechanical compatibility while offering increased inventory availability (3288 pieces in stock) and enhanced regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 2474-35L and 2474R-35L are active products with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

The 2474-35L is suitable for applications where RoHS non-compliance is acceptable or where legacy component specifications are required.

The 2474R-35L is the preferred selection for new designs and applications requiring ROHS3 compliance. This variant offers superior regulatory alignment while maintaining complete electrical and mechanical equivalence. The 2474R-35L also provides higher inventory availability, reducing procurement lead times.

Both parts carry REACH Unaffected status and EAR99 export classification, ensuring consistent regulatory treatment across supply chain operations.

Frequently Asked Questions (FAQ)

Q: Are the 2474-35L and 2474R-35L electrically interchangeable?

A: Yes. Both parts deliver identical inductance (680 µH ±15%), current rating (490 mA), DC resistance (1.5Ohm max), and operating temperature range (-55°C to 125°C). They are direct electrical equivalents.

Q: Do these parts have identical physical dimensions?

A: Yes. Both the 2474-35L and 2474R-35L share the same axial through-hole package with dimensions of 0.240" Dia × 0.740" L (6.10mm × 18.80mm), ensuring identical PCB footprint compatibility.

Q: What is the primary difference between these two parts?

A: The 2474R-35L is ROHS3 compliant, while the 2474-35L is RoHS non-compliant. All other electrical, mechanical, and regulatory parameters are identical.

Q: Which part should be selected for new product designs?

A: The 2474R-35L is recommended for new designs due to its ROHS3 compliance status, which aligns with current regulatory requirements and supply chain standards.

Q: Are there any temperature or frequency limitations that affect substitution?

A: No. Both parts operate across the same temperature range (-55°C to 125°C) and are tested at 1 kHz. Substitution does not introduce any thermal or frequency-related constraints.

Q: Can these parts be used in high-frequency applications?

A: The inductance test frequency is specified at 1 kHz. Application suitability at higher frequencies requires evaluation of the self-resonant frequency and Q factor, which are not provided in the component specifications.
