Bourns 8230-84 470µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 8230-84 is a 470 µH unshielded drum core wirewound inductor rated for 50 mA continuous current with a maximum DC resistance of 42Ohm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for general-purpose filtering and energy storage applications in electronic circuits.

The 8230-84 carries an obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs and ongoing production requirements. The primary substitute maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 8230-84 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 470 µH (exact match required)
• Inductance Tolerance: ±10% (exact match required)
• Current Rating: 50 mA minimum (exact match required)
• DC Resistance: 42Ohm maximum (exact match required)
• Core Material: Ferrite drum core (exact match required)
• Shielding Configuration: Unshielded (exact match required)
• Mounting Technology: Through hole axial (exact match required)
• Physical Footprint: 0.120" Dia x 0.300" L (exact match required)
• Operating Temperature Range: -55°C to 105°C minimum (exact match required)

The substitute part 8230-84-RC meets all these criteria and represents a direct functional equivalent with identical electrical performance and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 8230-84-RC be used as a direct replacement for the 8230-84 in existing designs?

A: Yes. The 8230-84-RC is a direct functional equivalent with identical inductance (470 µH), current rating (50 mA), DC resistance (42Ohm max), core material (ferrite drum core), physical dimensions (0.120" Dia x 0.300" L), and operating temperature range (-55°C to 105°C). No circuit modifications are required.

Q: What is the primary reason to transition from the 8230-84 to the 8230-84-RC?

A: The 8230-84 carries an obsolete product status, which creates supply chain risk and potential manufacturing discontinuation. The 8230-84-RC maintains active product status with guaranteed availability. Additionally, the 8230-84-RC is ROHS3 compliant, whereas the 8230-84 is not, which is critical for applications subject to environmental regulations.

Q: Are there any electrical performance differences between these two parts?

A: No. Both components have identical electrical specifications: 470 µH inductance at ±10% tolerance, 50 mA current rating, 42Ohm maximum DC resistance, Q factor of 30 at 790 kHz, and 6 MHz self-resonant frequency.

Q: Do the physical dimensions and mounting characteristics differ?

A: No. Both parts are through-hole axial components with identical dimensions of 0.120" diameter by 0.300" length (3.05mm x 7.62mm). They are mechanically interchangeable on PCBs designed for the 8230-84.

Q: What packaging options are available for each part?

A: The 8230-84 is supplied in standard packaging, while the 8230-84-RC is available in bulk packaging. Bulk packaging is typically preferred for high-volume production runs.

Q: Are there any compliance or certification differences?

A: Yes. The 8230-84-RC is ROHS3 compliant, whereas the 8230-84 is RoHS non-compliant. Both are REACH unaffected and classified under ECCN EAR99. For applications in regulated markets, the 8230-84-RC is the required choice.
