Bourns 9230-36 4.7µH Axial Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9230-36 is a 4.7 µH unshielded molded inductor rated for 320 mA with 1.2Ω maximum DC resistance, designed for through-hole axial mounting. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 9230-36 operates across -55°C to 125°C with ferrite core construction and ±10% inductance tolerance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9230-36 is determined by the following critical parameters: inductance value (4.7 µH), inductance tolerance (±10%), DC resistance (1.2Ω maximum), current rating capability, core material, shielding configuration, mounting type (through-hole axial), package dimensions, and operating temperature range.

The substitute parts identified are grouped into two categories:

Direct Manufacturer Equivalent: 9230-36-RC (Bourns Inc.) maintains identical electrical specifications and physical dimensions as the main part, with the primary distinction being active product status and RoHS3 compliance.

Similar Cross-Manufacturer Substitutes: 1025-36K and 1025R-36K (API Delevan Inc.) share the same inductance, tolerance, DC resistance, and physical dimensions. These parts differ in current rating (239 mA versus 320 mA), core material (iron versus ferrite), operating temperature maximum (105°C versus 125°C), and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 9230-36-RC

The 9230-36-RC is the direct equivalent from Bourns Inc., maintaining all electrical and mechanical specifications of the obsolete 9230-36. This part is classified as active product status and achieves RoHS3 compliance. Selection of 9230-36-RC eliminates design risk and ensures full parameter compatibility without circuit redesign.

Secondary Recommendation: 1025R-36K

The 1025R-36K from API Delevan Inc. is suitable for applications where the 320 mA current rating of the main part is not fully utilized. This part maintains identical inductance, tolerance, DC resistance, and physical dimensions. The 1025R-36K is RoHS3 compliant and active in production. Applications operating below 239 mA and within the -55°C to 105°C temperature range can use this substitute without circuit modification.

Conditional Recommendation: 1025-36K

The 1025-36K shares electrical and mechanical compatibility with the main part but is supplied in Tape & Reel packaging and does not achieve RoHS3 compliance. This part is suitable only for applications where RoHS compliance is not required and tape-and-reel packaging is acceptable for assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 9230-36-RC be used as a direct replacement for the 9230-36?

A: Yes. The 9230-36-RC maintains identical inductance (4.7 µH), tolerance (±10%), current rating (320 mA), DC resistance (1.2Ω), core material (ferrite), operating temperature range (-55°C to 125°C), and physical dimensions (0.095" Dia x 0.250" L). The primary differences are active product status and RoHS3 compliance.

Q: What is the impact of using 1025-36K or 1025R-36K as substitutes?

A: Both API Delevan parts maintain the same inductance, tolerance, DC resistance, and physical dimensions. The current rating is reduced from 320 mA to 239 mA, and the maximum operating temperature is reduced from 125°C to 105°C. Core material differs from ferrite to iron. These parts are suitable only for applications operating within these reduced specifications.

Q: Are there packaging differences between substitute parts?

A: Yes. The 9230-36 and 9230-36-RC are supplied in bulk packaging. The 1025-36K is supplied in Tape & Reel (TR) packaging, while 1025R-36K is supplied in bulk packaging. Packaging selection depends on assembly process requirements.

Q: Which substitute part has the best compliance status?

A: Both 9230-36-RC and 1025R-36K achieve RoHS3 compliance. The 1025-36K and original 9230-36 are RoHS non-compliant. For applications requiring RoHS compliance, select either 9230-36-RC or 1025R-36K.

Q: Can I use a substitute part if my circuit requires the full 320 mA current rating?

A: No. The API Delevan parts (1025-36K and 1025R-36K) are rated for 239 mA maximum. Use only 9230-36-RC for applications requiring the full 320 mA current rating.

Q: What is the difference between ferrite and iron core materials in these inductors?

A: The 9230-36 and 9230-36-RC use ferrite cores, while 1025-36K and 1025R-36K use iron cores. Both materials achieve the same inductance value, tolerance, Q factor, and self-resonant frequency as specified. Core material selection affects magnetic properties and thermal characteristics but does not alter the specified electrical parameters for these parts.
