Bourns 8230-42 Fixed Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 8230-42 is an 8.2 µH unshielded drum core wirewound inductor rated for 210 mA with a maximum DC resistance of 2.7 Ohm. This through-hole axial component is designed for general-purpose RF and filtering applications requiring moderate inductance values and current handling. The 8230-42 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 8230-42 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical inductance value (8.2 µH), tolerance (±10%), current rating (210 mA), DC resistance (2.7 Ohm maximum), core material (ferrite), shielding configuration (unshielded), and physical form factor (through-hole axial). The Q factor at 7.9 MHz and self-resonant frequency must also remain constant. Mounting type and package dimensions are non-negotiable for direct board-level replacement without redesign.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 8230-42-RC is a direct electrical and mechanical equivalent to the 8230-42. All critical performance parameters—inductance, current rating, DC resistance, frequency response, and thermal operating range—are identical. The primary distinction is product lifecycle status: the 8230-42 is obsolete, while the 8230-42-RC maintains active production status.

For new designs and ongoing production requiring this inductor specification, the 8230-42-RC is the appropriate selection. The 8230-42-RC additionally provides ROHS3 compliance, meeting modern regulatory requirements for electronic components in regulated markets. The 8230-42-RC is supplied in bulk packaging, suitable for manufacturing environments.

Frequently Asked Questions (FAQ)
