Bourns 5724 Fixed Inductor - Equivalent & Substitute Parts

Part Overview

The Bourns 5724 is a 4 mH unshielded toroidal inductor rated for 1.75 A with a maximum DC resistance of 1.16 Ohm. This through-hole component features an iron powder core and operates across a temperature range of -55°C to 105°C. The 5724 is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 5724 is determined by electrical and mechanical parameter equivalence within the 5700 series. The substitute part 5724-RC maintains identical electrical specifications: 4 mH inductance at ±15% tolerance, 1.75 A current rating, and 1.16 Ohm maximum DC resistance. Both components use iron powder cores, operate unshielded, and function across the same temperature range (-55°C to 105°C) with inductance measured at 1 kHz.

The primary distinction between these parts is product status and packaging configuration. The 5724 is obsolete, while the 5724-RC is active. The 5724-RC is supplied in bulk packaging and carries RoHS3 compliance, whereas the original 5724 is RoHS non-compliant. Both maintain REACH unaffected status and EAR99 export classification.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 5724-RC serves as the direct substitute for the obsolete 5724. Both components are electrically and mechanically equivalent across all specified parameters. Selection between these parts is determined by regulatory and procurement requirements rather than functional performance.

For new designs or applications requiring regulatory compliance, the 5724-RC is the appropriate choice due to its active product status and RoHS3 compliance. The 5724-RC is currently in stock with 1,359 pieces available. For legacy systems or applications where RoHS compliance is not mandated, the original 5724 remains functionally equivalent, though availability is limited to existing inventory (952 pieces).

Both parts maintain identical REACH unaffected status and EAR99 export classification, ensuring consistent regulatory treatment across supply chain applications.

Frequently Asked Questions (FAQ)

Q: Are the 5724 and 5724-RC electrically interchangeable?

A: Yes. Both components provide identical inductance (4 mH at ±15% tolerance), current rating (1.75 A), DC resistance (1.16 Ohm maximum), core material (iron powder), and operating temperature range (-55°C to 105°C). Electrical performance is equivalent.

Q: What is the primary reason to substitute the 5724 with the 5724-RC?

A: The 5724 is classified as obsolete. The 5724-RC is the active equivalent within the Bourns 5700 series, ensuring long-term availability and supply chain continuity.

Q: Does the 5724-RC meet RoHS requirements?

A: Yes. The 5724-RC is RoHS3 compliant. The original 5724 is RoHS non-compliant. Selection depends on whether your application or regulatory environment requires RoHS compliance.

Q: Are there physical dimension differences between these parts?

A: Yes. The 5724 has a dimension of 0.875" Dia x 0.437" W (22.22mm x 11.10mm). The 5724-RC has a dimension of 2.125" Dia x 0.937" W (53.97mm x 23.80mm). Both are radial, vertical (open) package types suitable for through-hole mounting. Physical layout compatibility must be verified for your specific application.

Q: What packaging is supplied for each part?

A: The 5724 is supplied with standard packaging. The 5724-RC is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are export classifications identical?

A: Yes. Both the 5724 and 5724-RC carry EAR99 classification and maintain REACH unaffected status, ensuring consistent export and regulatory treatment.
