Bourns 8230-82 390µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 8230-82 is a 390 µH unshielded drum core wirewound inductor rated for 55 mA continuous current with a maximum DC resistance of 35Ohm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance values in compact form factors.

The 8230-82 carries an obsolete product status, making identification of equivalent and substitute parts essential for ongoing design support, maintenance, and production continuity. Active alternatives within the same series provide direct functional replacement while offering improved compliance certifications.

• Operating Temperature: -55°C to 105°C range
• Mounting and Package: Through-hole axial configuration with identical physical dimensions (0.120" Dia × 0.300" L)

The 8230-82-RC variant meets all electrical and mechanical specifications while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 8230-82-RC is the direct functional equivalent of the obsolete 8230-82, providing identical electrical performance and mechanical compatibility. Selection of the 8230-82-RC is supported by:

• Active Product Status: The 8230-82-RC maintains current manufacturing and distribution through Bourns Inc., ensuring long-term availability and supply chain stability.
• Regulatory Compliance: The 8230-82-RC achieves ROHS3 compliance, meeting current environmental and material restriction requirements. The original 8230-82 is RoHS non-compliant.
• Certification Equivalence: Both parts share identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications, with REACH Unaffected status maintained across both variants.
• Electrical and Mechanical Parity: All specified inductance, current, resistance, frequency, and dimensional parameters are identical, enabling direct pin-for-pin and form-factor replacement.

Frequently Asked Questions (FAQ)

Q: Can the 8230-82-RC be used as a direct replacement for the 8230-82?

A: Yes. The 8230-82-RC is electrically and mechanically identical to the 8230-82 across all specified parameters, including inductance (390 µH), current rating (55 mA), DC resistance (35Ohm max), frequency characteristics, operating temperature range, and physical dimensions. Through-hole axial mounting and package compatibility are maintained.

Q: What is the primary difference between the 8230-82 and 8230-82-RC?

A: The 8230-82-RC is an active product variant with ROHS3 compliance, while the 8230-82 is obsolete and RoHS non-compliant. Both parts are functionally equivalent. The packaging format differs (the 8230-82-RC is supplied in bulk packaging), but electrical and mechanical specifications remain identical.

Q: Are there any compliance or certification differences?

A: The 8230-82-RC meets ROHS3 environmental compliance standards, whereas the 8230-82 does not. Both parts maintain identical ECCN, HTSUS, and REACH classifications. For applications subject to RoHS requirements, the 8230-82-RC is the appropriate selection.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by exact matching of inductance value (390 µH), tolerance (±10%), current rating (55 mA minimum), DC resistance (35Ohm maximum), core material (ferrite), shielding configuration (unshielded), frequency characteristics (Q @ 790kHz and self-resonant frequency), operating temperature range (-55°C to 105°C), and physical dimensions (0.120" Dia × 0.300" L). Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Is the 8230-82-RC available in the same packaging as the 8230-82?

A: The 8230-82-RC is supplied in bulk packaging, while the original 8230-82 packaging format is not specified in the provided data. Both variants maintain identical through-hole axial form factors and physical dimensions, ensuring compatibility with existing PCB layouts and assembly processes.
