Bourns 8230-46 Equivalent & Substitute Parts

Part Overview

The Bourns 8230-46 is a 12 µH unshielded drum core wirewound inductor rated for 210 mA with a maximum DC resistance of 2.7 Ohm. This through-hole axial component operates across a temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 8230-46 carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for legacy systems or ongoing production requirements.

Substitute Part Grouping Explanation

Substitution of the Bourns 8230-46 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for inductance value, tolerance, current rating, DC resistance, core material, shielding configuration, frequency characteristics, temperature range, and physical dimensions.

The 8230-46-RC qualifies as a direct substitute based on complete parameter alignment across these criteria. The primary distinction between the main part and substitute is product status and packaging configuration, not electrical or mechanical performance.
