Bourns 6000-4R7M-RC Equivalent & Substitute Parts

Part Overview

The Bourns 6000-4R7M-RC is a 4.7 µH unshielded drum core wirewound inductor rated for 4.6 A continuous current with 30mOhm maximum DC resistance. This through-hole component is designed for radial, vertical cylinder mounting in applications requiring fixed inductance values with ferrite core construction.

The 6000 series has been designated as "Not For New Designs," making identification of equivalent substitute parts essential for ongoing production support and design updates. Active alternative models from Bourns and other manufacturers provide comparable electrical and mechanical characteristics while offering current product status and extended availability.

Substitute Part Grouping Explanation

Substitute parts for the 6000-4R7M-RC are classified based on electrical and mechanical compatibility within the following criteria:

Direct Substitutes maintain identical or equivalent electrical specifications: 4.7 µH inductance, ±20% tolerance, 4.6 A current rating, 30mOhm maximum DC resistance, ferrite core construction, unshielded configuration, and through-hole radial vertical cylinder mounting. Physical dimensions and operating temperature ranges may vary within acceptable limits for the application.

Similar Substitutes share the same inductance value (4.7 µH), core material (ferrite), and mounting type (through-hole radial vertical cylinder) but differ in one or more electrical parameters such as current rating, DC resistance, or operating temperature range. These parts require application-level verification to confirm suitability.

Engineering Selection Recommendations

RLB9012-4R7ML is the primary direct substitute for the 6000-4R7M-RC. Both components are manufactured by Bourns Inc. and share identical electrical specifications: 4.7 µH inductance, ±20% tolerance, 4.6 A current rating, and 30mOhm maximum DC resistance. Physical dimensions are equivalent (0.354" diameter, 0.480" maximum height). The RLB9012-4R7ML offers extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) and active product status, making it suitable for direct replacement in existing designs. Both parts are ROHS3 compliant and REACH unaffected.

AIUR-02H-4R7M from Abracon LLC shares the same inductance value and core material but differs in current rating (2.5 A versus 4.6 A), DC resistance (34mOhm maximum versus 30mOhm), and physical dimensions (0.830" diameter, 0.831" height). This part is suitable only for applications where the reduced current rating and increased DC resistance are acceptable. Operating temperature range is narrower (-25°C to 85°C). Selection of this part requires verification that circuit current demands do not exceed 2.5 A and that the larger footprint accommodates PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can RLB9012-4R7ML be used as a direct replacement for 6000-4R7M-RC?

A: Yes. Both parts share identical inductance (4.7 µH), tolerance (±20%), current rating (4.6 A), and DC resistance (30mOhm maximum). Physical dimensions are equivalent. The RLB9012-4R7ML has active product status and extended temperature range, making it the recommended substitute.

Q: What are the limitations of AIUR-02H-4R7M as a substitute?

A: The AIUR-02H-4R7M has a reduced current rating of 2.5 A compared to 4.6 A for the main part. DC resistance is higher at 34mOhm maximum. Physical dimensions are significantly larger (0.830" diameter versus 0.354"). Operating temperature range is narrower (-25°C to 85°C). Use this part only if circuit current remains below 2.5 A and PCB layout accommodates the larger footprint.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. The 6000-4R7M-RC, RLB9012-4R7ML, and AIUR-02H-4R7M are all ROHS3 compliant and REACH unaffected.

Q: What is the difference in packaging between the main part and RLB9012-4R7ML?

A: The 6000-4R7M-RC is supplied in bulk packaging, while RLB9012-4R7ML is supplied in tray packaging. Both are through-hole radial vertical cylinder components with identical electrical and mechanical specifications.

Q: Can AIUR-02H-4R7M be used in high-current applications?

A: No. The AIUR-02H-4R7M is rated for 2.5 A maximum continuous current, which is insufficient for applications requiring the full 4.6 A rating of the 6000-4R7M-RC or RLB9012-4R7ML. Exceeding the current rating will result in component failure.
