Bourns 8230-74 180µH Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 8230-74 is a 180 µH unshielded drum core wirewound inductor rated for 79 mA maximum current with 17Ohm DC resistance. This through-hole axial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 8230-74 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy systems.

Substitute Part Grouping Explanation

Substitution for the Bourns 8230-74 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match:

  • Inductance value: 180 µH
  • Tolerance: ±10%
  • Current rating: 79 mA minimum
  • DC resistance: 17Ohm maximum
  • Core type: Ferrite drum core
  • Shielding configuration: Unshielded
  • Q factor: 30 @ 790kHz
  • Self resonant frequency: 10MHz
  • Operating temperature range: -55°C ~ 105°C
  • Mounting and package: Through-hole axial configuration
  • Physical dimensions: 0.120" Dia x 0.300" L (3.05mm x 7.62mm)

The 8230-74-RC meets all these criteria and is classified as a direct substitute.

Engineering Selection Recommendations

The 8230-74-RC is the direct substitute for the obsolete 8230-74. Both parts are manufactured by Bourns Inc. within the same 8230 series and maintain identical electrical and mechanical specifications.

The primary distinction is product status and regulatory compliance. The 8230-74-RC is active in production and carries ROHS3 compliance, whereas the original 8230-74 is obsolete and RoHS non-compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the 8230-74-RC is the appropriate selection.

Both parts are functionally interchangeable in through-hole axial mounting applications requiring 180 µH inductance at 79 mA current rating across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 8230-74-RC be used as a direct replacement for the 8230-74?

A: Yes. The 8230-74-RC is electrically and mechanically identical to the 8230-74. All critical parameters including inductance, current rating, DC resistance, core material, shielding, Q factor, resonant frequency, temperature range, and physical dimensions are equivalent.

Q: What is the difference between the 8230-74 and 8230-74-RC?

A: The 8230-74-RC is the active production variant with ROHS3 compliance. The original 8230-74 is obsolete and RoHS non-compliant. The "-RC" designation indicates the compliant version within the same product line.

Q: Are there packaging differences between these parts?

A: The 8230-74-RC is supplied in bulk packaging, whereas the original 8230-74 packaging specification is not provided. Both parts use identical axial through-hole package configuration and physical dimensions.

Q: What applications are suitable for this inductor?

A: The 180 µH inductance value, 79 mA current rating, and 10MHz self-resonant frequency make this component suitable for RF filtering, signal conditioning, and power supply applications operating in the sub-megahertz to low-megahertz frequency range.

Q: Can this part be used in new designs?

A: Yes. The 8230-74-RC is the recommended choice for new designs due to its active production status and ROHS3 compliance. The original 8230-74 should be reserved for legacy system maintenance only.
