Equivalent & Substitute Parts for 2474-09L

Part Overview

The 2474-09L is a 4.7 µH unshielded molded inductor manufactured by API Delevan Inc., designed for through-hole mounting applications. This ferrite-core component operates across a temperature range of -55°C to 125°C with a current rating of 4.01 A and maximum DC resistance of 22 mOhm. The part is currently active in production with 858 pieces available in new original stock.

Identifying equivalent and substitute parts becomes necessary when the primary part number reaches end-of-life status, when supply constraints occur, or when design revisions require components with improved compliance certifications. The 2474-09L is RoHS non-compliant, making substitution with compliant alternatives essential for applications subject to RoHS regulations.

Substitute Part Grouping Explanation

Substitution eligibility for the 2474-09L is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for inductance value, tolerance, current rating, saturation current, DC resistance, core material, shielding configuration, mounting type, package style, and physical dimensions.

The 2474R-09L qualifies as a direct substitute because it matches all electrical parameters (4.7 µH ±15%, 4.01 A rating, 2.9 A saturation, 22 mOhm DCR) and mechanical specifications (unshielded ferrite-core, through-hole axial package, 0.240" Dia x 0.740" L). The primary distinction between these parts is compliance certification: the 2474-09L is RoHS non-compliant, while the 2474R-09L is ROHS3 compliant. Both parts operate across the identical temperature range (-55°C to 125°C) and share the same series heritage within the API Delevan 2474 product family.

Parameter Comparison

Engineering Selection Recommendations

The 2474R-09L serves as the direct equivalent substitute for the 2474-09L. Both components are manufactured by API Delevan Inc. and maintain active product status with full production availability.

For applications subject to RoHS regulations: The 2474R-09L is the appropriate selection due to its ROHS3 compliance certification. The 2474-09L does not meet RoHS requirements and should not be used in designs requiring regulatory compliance.

For applications without RoHS requirements: Either part may be selected based on inventory availability and supply chain considerations. The 2474-09L currently has 858 pieces in stock, while the 2474R-09L has 1682 pieces available.

For new designs: The 2474R-09L is the preferred choice to ensure forward compatibility with evolving regulatory requirements and to align with industry compliance standards.

Both parts share identical electrical performance characteristics, mechanical dimensions, and thermal operating ranges, ensuring functional interchangeability within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the 2474R-09L be used as a direct replacement for the 2474-09L in existing designs?

A: Yes. The 2474R-09L is electrically and mechanically identical to the 2474-09L across all specified parameters: 4.7 µH inductance, 4.01 A current rating, 22 mOhm DCR, unshielded ferrite core, and axial through-hole package with identical dimensions. No circuit modifications or PCB layout changes are required.

Q: What is the primary difference between these two part numbers?

A: The 2474R-09L is ROHS3 compliant, while the 2474-09L is RoHS non-compliant. All other specifications, including electrical performance and physical form factor, are identical.

Q: Are there any thermal or frequency performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and are tested at the same reference frequency (1 kHz). No performance differences exist in thermal behavior or frequency response.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. The 2474-09L and 2474R-09L have identical physical dimensions (0.240" Dia x 0.740" L) and mounting type (through-hole axial), allowing direct substitution without board redesign or component repositioning.

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

A: The 2474R-09L is recommended for new designs to ensure compliance with current regulatory standards and to maintain consistency with industry best practices for component selection.

Q: Is there a difference in current-carrying capacity between these parts?

A: No. Both parts have identical current ratings of 4.01 A and identical saturation current (Isat) of 2.9 A. DC resistance is also identical at 22 mOhm maximum.

Q: Do these parts have different REACH or export classification status?

A: No. Both parts share identical REACH status (REACH Unaffected) and export classification (ECCN: EAR99, HTSUS: 8504.50.4000).
