5900-470-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5900-470-RC is a 47 µH unshielded drum core wirewound inductor rated for 3.1 A continuous current with a maximum DC resistance of 45 mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is ROHS3 compliant. The part is currently active in production with substantial inventory availability. Substitute parts are identified to provide design flexibility when the primary part is unavailable or when application requirements permit alternative electrical or mechanical characteristics within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

The Abracon LLC AIAP-03-470K qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Inductance: 47 µH (identical)
• Inductance Tolerance: ±10% (identical)
• Shielding: Unshielded (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Axial (identical)
• Inductance Test Frequency: 1 kHz (identical)
• RoHS Status: ROHS3 Compliant (identical)

Allowable Variations:

• Current Rating: 3.98 A (substitute) vs. 3.1 A (main part) — higher rating provides margin
• DC Resistance: 35 mOhm Max (substitute) vs. 45 mOhm Max (main part) — lower resistance is acceptable
• Operating Temperature: -55°C to 125°C (substitute) vs. -55°C to 105°C (main part) — extended upper range is acceptable
• Physical Dimensions: 0.449" Dia x 0.902" L (substitute) vs. 0.453" Dia x 0.900" L (main part) — within tolerance for through-hole axial mounting

Parameter Comparison

Engineering Selection Recommendations

Both the 5900-470-RC and AIAP-03-470K are active production components with ROHS3 compliance and REACH unaffected status. The Abracon AIAP-03-470K substitute provides equivalent inductance and tolerance specifications with improved electrical performance characteristics: higher current rating (3.98 A vs. 3.1 A) and lower DC resistance (35 mOhm vs. 45 mOhm). The extended operating temperature range (-55°C to 125°C) accommodates broader thermal environments. Physical dimensions are compatible with standard through-hole axial mounting footprints. Selection between these parts depends on supply availability, cost considerations, and specific thermal or current margin requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the AIAP-03-470K replace the 5900-470-RC in all applications?

A: Yes, provided the application does not require the specific thermal characteristics of the Bourns part. The Abracon substitute meets or exceeds all critical electrical parameters: inductance, tolerance, current rating, and DC resistance. Physical dimensions are compatible with standard through-hole axial PCB layouts.

Q: What is the significance of the lower DC resistance in the substitute part?

A: Lower DC resistance (35 mOhm vs. 45 mOhm) reduces resistive losses and heat generation during operation. This is a favorable characteristic that improves efficiency and thermal performance in the application circuit.

Q: Are there any packaging differences between these parts?

A: The main part is supplied in Tray packaging, while the substitute is supplied in Bulk packaging. Both use identical Axial through-hole mounting. Packaging format does not affect electrical performance or PCB compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 5900-470-RC and AIAP-03-470K are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and commercial applications.

Q: What is the impact of the extended temperature range in the substitute?

A: The Abracon part operates to 125°C versus 105°C for the Bourns part. This extended upper limit provides additional thermal margin and may be beneficial in high-temperature environments, though it does not restrict use in applications requiring only the -55°C to 105°C range.
