API Delevan 2474-13L Fixed Inductor Equivalent & Substitute Parts

Part Overview

The API Delevan 2474-13L is a 10 µH unshielded molded inductor rated for 3.27 A continuous current with a maximum DC resistance of 33 mOhm. This through-hole axial component operates across the temperature range of -55°C to 125°C and is constructed with a ferrite core. The part is currently active in production with 688 pieces available in new original stock.

Identification of equivalent and substitute parts becomes necessary when the primary part number reaches end-of-life status, when supply constraints occur, or when design requirements mandate compliance with specific regulatory standards such as RoHS3. The 2474-13L is RoHS non-compliant, making substitution critical for applications requiring RoHS3 compliance.

Substitute Part Grouping Explanation

Substitution of the API Delevan 2474-13L is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for inductance value, inductance tolerance, current rating, saturation current, DC resistance, core material, shielding configuration, operating temperature range, mounting type, package type, and physical dimensions.

The API Delevan 2474R-13L qualifies as a direct substitute because it matches all critical parameters of the 2474-13L. Both parts deliver 10 µH inductance at ±15% tolerance, support 3.27 A continuous current with 2 A saturation current, exhibit 33 mOhm maximum DC resistance, utilize ferrite cores in unshielded configurations, operate across -55°C to 125°C, employ through-hole axial mounting, and share identical physical dimensions of 0.240" diameter by 0.740" length.

The primary distinction between these parts is regulatory compliance status: the 2474-13L is RoHS non-compliant, while the 2474R-13L is RoHS3 compliant. This difference makes the 2474R-13L the appropriate selection for applications subject to RoHS3 requirements.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 2474R-13L serves as the direct substitute for the 2474-13L in all applications. Both parts are active products with full manufacturing support and identical electrical and mechanical specifications.

Selection between these parts depends on regulatory compliance requirements:

Select the 2474-13L when RoHS3 compliance is not mandated and the non-compliant status is acceptable for the application.

Select the 2474R-13L when RoHS3 compliance is required or when future-proofing against regulatory changes is necessary. The 2474R-13L is RoHS3 compliant and provides equivalent performance with enhanced regulatory standing.

Both parts maintain active product status, ensuring continued availability and manufacturing support. The 2474R-13L currently has higher inventory availability at 3,037 pieces compared to 688 pieces for the 2474-13L.

Frequently Asked Questions (FAQ)

Q: Can the 2474R-13L replace the 2474-13L in existing designs without modification?

A: Yes. The 2474R-13L is electrically and mechanically identical to the 2474-13L. Both parts deliver 10 µH inductance at ±15% tolerance, support 3.27 A continuous current, exhibit 33 mOhm maximum DC resistance, and share identical through-hole axial packaging with 0.240" diameter by 0.740" length dimensions. No circuit modifications or PCB layout changes are required.

Q: What is the primary difference between the 2474-13L and 2474R-13L?

A: The primary difference is regulatory compliance status. The 2474-13L is RoHS non-compliant, while the 2474R-13L is RoHS3 compliant. All electrical and mechanical parameters are identical.

Q: Are both parts currently in production?

A: Yes. Both the 2474-13L and 2474R-13L maintain active product status with full manufacturing support from API Delevan Inc.

Q: Which part should be selected for new designs?

A: The 2474R-13L is the appropriate selection for new designs because it provides RoHS3 compliance while maintaining identical performance specifications. This ensures regulatory alignment and future compatibility.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts measure 0.240" diameter by 0.740" length (6.10mm by 18.80mm). They are mechanically interchangeable in through-hole axial mounting applications.

Q: What is the saturation current specification for these inductors?

A: Both parts have a saturation current (Isat) of 2 A, which is lower than the continuous current rating of 3.27 A. Applications must account for this saturation threshold in circuit design.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both parts operate across the temperature range of -55°C to 125°C, making them suitable for industrial and automotive applications requiring extended temperature performance.

Q: What core material is used in these inductors?

A: Both parts utilize ferrite cores in unshielded configurations. The ferrite material provides stable inductance characteristics across the operating temperature range.
