Bourns 8230-72 Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 8230-72 is a 150 µH unshielded drum core wirewound inductor rated for 85 mA continuous current with a maximum DC resistance of 15 Ohm. 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 8230-72 carries an obsolete product status, making it necessary to identify active equivalent parts for new designs and ongoing production requirements. The substitute part 8230-72-RC provides functional equivalence while maintaining active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

The 8230-72-RC qualifies as a direct substitute for the 8230-72 based on the following critical parameters:

• Inductance Value: Both parts specify 150 µH with ±10% tolerance
• Current Rating: Both rated for 85 mA continuous operation
• DC Resistance: Both maintain 15 Ohm maximum DC resistance
• Core Type and Shielding: Both use ferrite drum core construction with unshielded configuration
• Electrical Performance: Both exhibit Q factor of 30 @ 790 kHz and 11 MHz self-resonant frequency
• Temperature Range: Both operate across -55°C to 105°C
• Physical Form Factor: Both are through-hole axial components with identical dimensions (0.120" Dia × 0.300" L)
• Frequency Test Specification: Both tested at 790 kHz inductance measurement frequency

The substitution is based strictly on electrical equivalence and mechanical compatibility. No parameter deviations exist between the main part and substitute.

Engineering Selection Recommendations

The 8230-72-RC is the appropriate selection for applications currently using or specifying the 8230-72. The substitute part maintains complete electrical and mechanical equivalence while offering the following advantages:

• Active Product Status: The 8230-72-RC is an active product, ensuring long-term availability and supply chain continuity compared to the obsolete 8230-72
• Improved Compliance: The 8230-72-RC achieves ROHS3 compliance, whereas the 8230-72 is RoHS non-compliant, meeting modern regulatory requirements for electronic components in restricted substance directives
• Identical Electrical Performance: All critical electrical parameters—inductance, current rating, DC resistance, Q factor, and frequency characteristics—are identical between both parts
• Mechanical Interchangeability: Both components share identical physical dimensions and through-hole axial mounting configuration, enabling direct PCB layout compatibility without redesign

For new designs or production transitions, the 8230-72-RC should be specified to ensure compliance with current environmental regulations and sustained component availability.

Frequently Asked Questions (FAQ)

Q: Can the 8230-72-RC be used as a direct replacement for the 8230-72 on existing PCBs?

A: Yes. The 8230-72-RC is mechanically and electrically identical to the 8230-72. Both components have the same physical dimensions (0.120" Dia × 0.300" L), axial through-hole mounting configuration, and all electrical specifications including inductance, current rating, and DC resistance. No PCB modifications are required.

Q: What is the primary reason to transition from the 8230-72 to the 8230-72-RC?

A: The 8230-72 is classified as obsolete, while the 8230-72-RC maintains active product status. Additionally, the 8230-72-RC is ROHS3 compliant, whereas the 8230-72 is RoHS non-compliant. These factors make the 8230-72-RC the appropriate choice for new designs and ongoing production.

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

A: No. Both parts specify identical inductance (150 µH ±10%), current rating (85 mA), DC resistance (15 Ohm maximum), Q factor (30 @ 790 kHz), and self-resonant frequency (11 MHz). Electrical performance is equivalent.

Q: What packaging options are available for these parts?

A: The 8230-72 is supplied in standard packaging, while the 8230-72-RC is supplied in bulk packaging. Both maintain the same component specifications and through-hole axial form factor suitable for manual or automated PCB assembly.

Q: Are both parts suitable for the full operating temperature range of -55°C to 105°C?

A: Yes. Both the 8230-72 and 8230-72-RC are rated for continuous operation across the temperature range of -55°C to 105°C, making them suitable for industrial and extended-temperature applications.

Q: What are the compliance certifications for each part?

A: The 8230-72-RC is ROHS3 compliant and REACH unaffected. The 8230-72 is RoHS non-compliant but REACH unaffected. Both parts carry EAR99 export classification and HTSUS code 8504.50.4000.
