Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 8230-92 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 1 mH with ±10% tolerance
• Current Rating: 38 mA maximum
• DC Resistance: 72 Ohm maximum
• Core Type: Ferrite drum core, unshielded
• Frequency Characteristics: Q factor of 30 @ 790 kHz; self-resonant frequency of 3.4 MHz
• Operating Temperature: -55°C to 105°C
• Mounting Configuration: Through-hole axial package with 0.120" diameter × 0.300" length dimensions

The substitute part 8230-92-RC maintains identical electrical and mechanical specifications while differing in product status and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 8230-92-RC is the direct equivalent substitute for the obsolete 8230-92. Both components are manufactured by Bourns Inc. and share identical electrical specifications and physical dimensions.

The primary distinction is product lifecycle status: the 8230-92 is obsolete, while the 8230-92-RC maintains active production status. Additionally, the 8230-92-RC achieves RoHS3 compliance, whereas the original 8230-92 is RoHS non-compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the 8230-92-RC is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part functions identically within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Are the 8230-92 and 8230-92-RC electrically interchangeable?

A: Yes. Both components provide identical inductance (1 mH ±10%), current rating (38 mA), DC resistance (72 Ohm max), Q factor (30 @ 790 kHz), and self-resonant frequency (3.4 MHz). They operate across the same temperature range (-55°C to 105°C) and use identical ferrite drum core construction in unshielded axial configuration.

Q: What is the difference between the 8230-92 and 8230-92-RC?

A: The 8230-92-RC is the active production equivalent. The 8230-92 is classified as obsolete. The 8230-92-RC achieves RoHS3 compliance, while the 8230-92 does not. Physical dimensions and electrical performance are identical.

Q: Can I use the 8230-92-RC in place of the 8230-92 in existing designs?

A: Yes. The 8230-92-RC is a direct substitute with no design modifications required. Pin-to-pin compatibility, mounting footprint, and electrical behavior are identical.

Q: Does packaging type affect substitution eligibility?

A: The 8230-92 is supplied in standard packaging, while the 8230-92-RC is supplied in bulk packaging. This distinction affects procurement and handling but does not impact component performance or compatibility.

Q: Are there any compliance considerations when substituting these parts?

A: The 8230-92-RC is RoHS3 compliant, whereas the 8230-92 is not. If your application or regulatory environment requires RoHS compliance, the 8230-92-RC is the appropriate choice. Both components are REACH unaffected and classified under ECCN EAR99.
