Bourns 5900-472 4.7 mH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 5900-472 is a 4.7 mH unshielded drum core wirewound inductor rated for 340 mA continuous current with a maximum DC resistance of 3.7 Ohm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is specified for 1 kHz inductance testing. The 5900-472 carries an obsolete product status, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 5900-472 is determined by the following critical parameters: inductance value (4.7 mH), inductance tolerance (±10%), core construction (ferrite drum core wirewound), shielding configuration (unshielded), mounting method (through hole axial), and physical dimensions within tolerance. Current rating and DC resistance must support the application requirements without exceeding the original specifications. Operating temperature range and product status inform selection priority but do not restrict electrical compatibility.

The substitute parts are grouped as follows:

Direct Equivalent: 5900-472-RC (Bourns Inc.) — identical electrical specifications with active product status and improved RoHS3 compliance.

Similar Substitutes: 4590-475K (API Delevan Inc.) and AIAP-03-472K (Abracon LLC) — maintain the same inductance, tolerance, core type, and physical dimensions while offering variations in current rating, DC resistance, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The Bourns 5900-472-RC is the recommended direct substitute. It maintains identical electrical specifications (4.7 mH inductance, 340 mA current rating, 3.7 Ohm maximum DC resistance) and physical dimensions while offering active product status and RoHS3 compliance. This part provides the highest compatibility with existing designs and procurement continuity.

Secondary Selection: The API Delevan 4590-475K is suitable for applications where increased current headroom is acceptable. It provides 415 mA current rating and 260 mA saturation current, with DC resistance of 3.79 Ohm. Physical dimensions remain within tolerance (0.455" Dia × 0.900" L). This part is active but RoHS non-compliant. The extended operating temperature range to 125°C may benefit temperature-sensitive applications.

Tertiary Selection: The Abracon AIAP-03-472K offers the lowest DC resistance at 3.19 Ohm maximum, supporting 390 mA continuous current. Physical dimensions are within tolerance (0.449" Dia × 0.902" L). This part is active and RoHS3 compliant with an extended operating temperature range to 125°C. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints.

Selection priority is determined by compliance requirements, product availability, and application-specific current and resistance tolerances.

Frequently Asked Questions (FAQ)

Q: Can the 5900-472-RC directly replace the obsolete 5900-472?

A: Yes. The 5900-472-RC is electrically and mechanically identical to the 5900-472, with the same inductance (4.7 mH), current rating (340 mA), DC resistance (3.7 Ohm maximum), and physical dimensions (0.453" Dia × 0.900" L). The primary difference is active product status and RoHS3 compliance.

Q: What are the key differences between the Bourns 5900-472-RC and the API Delevan 4590-475K?

A: Both parts share the same 4.7 mH inductance, ±10% tolerance, and axial through-hole package. The 4590-475K offers higher current rating (415 mA vs. 340 mA) and lower saturation current (260 mA vs. 380 mA). DC resistance is marginally higher (3.79 Ohm vs. 3.7 Ohm). Physical dimensions are within tolerance. The 4590-475K is RoHS non-compliant and operates to 125°C.

Q: Is the Abracon AIAP-03-472K compatible with the original 5900-472 design?

A: The AIAP-03-472K maintains the same 4.7 mH inductance, ±10% tolerance, unshielded axial configuration, and through-hole mounting. Physical dimensions are within tolerance (0.449" Dia × 0.902" L). DC resistance is lower at 3.19 Ohm, and current rating is 390 mA. This part is RoHS3 compliant and operates to 125°C. Compatibility depends on whether the lower DC resistance and higher current rating are acceptable for the application.

Q: What packaging options are available for these substitutes?

A: The Bourns 5900-472-RC is supplied in Tray packaging. The API Delevan 4590-475K and Abracon AIAP-03-472K are supplied in Bulk packaging. Packaging selection should align with procurement and assembly requirements.

Q: Do these substitutes have different moisture sensitivity levels?

A: The Bourns 5900-472 and 5900-472-RC are rated as Not Applicable for MSL. The API Delevan 4590-475K is also Not Applicable. The Abracon AIAP-03-472K carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Q: Which substitute offers the best compliance profile?

A: Both the Bourns 5900-472-RC and Abracon AIAP-03-472K are RoHS3 compliant. The API Delevan 4590-475K is RoHS non-compliant. All three parts are REACH Unaffected and carry ECCN classification EAR99.
