Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 8230-76 is determined by strict equivalence across the following critical parameters:

• Inductance Value: 220 µH (±10% tolerance maintained)
• Current Rating: 73 mA minimum
• DC Resistance: 21 Ohm maximum
• Core Type: Ferrite drum core, unshielded
• Frequency Characteristics: Q factor of 30 @ 790 kHz; self-resonant frequency of 9 MHz
• Thermal Range: -55°C to 105°C operation
• Form Factor: Through-hole axial mounting with identical physical dimensions (0.120" Dia × 0.300" L)

The Bourns 8230-76-RC meets all substitution criteria as a direct functional equivalent, with identical electrical and mechanical specifications. The primary distinction is product status and regulatory compliance.

Engineering Selection Recommendations

The Bourns 8230-76-RC is the direct substitute for the obsolete 8230-76. Selection of the 8230-76-RC is justified on the following grounds:

• Electrical Equivalence: Identical inductance, current rating, DC resistance, and frequency characteristics ensure drop-in compatibility in existing circuit designs.
• Product Availability: The 8230-76-RC maintains active production status with confirmed inventory (1557 pcs), whereas the 8230-76 is obsolete with limited remaining stock (948 pcs).
• Regulatory Compliance: The 8230-76-RC achieves ROHS3 compliance, meeting current environmental and manufacturing standards. The original 8230-76 is non-compliant.
• Physical Compatibility: Identical through-hole axial form factor and dimensions ensure mechanical fit without PCB redesign.

For new designs or component replenishment, the 8230-76-RC is the appropriate selection. For legacy systems requiring the exact original part number, the 8230-76 remains available in limited quantity.

Frequently Asked Questions (FAQ)

Q: Can the 8230-76-RC be used as a direct replacement for the 8230-76 in existing circuits?

A: Yes. The 8230-76-RC is electrically and mechanically identical to the 8230-76. All electrical parameters—inductance, current rating, DC resistance, frequency response, and thermal range—are equivalent. The components are pin-compatible and require no circuit modifications.

Q: What is the difference between the 8230-76 and 8230-76-RC?

A: The primary differences are product status and regulatory compliance. The 8230-76 is obsolete and RoHS non-compliant. The 8230-76-RC is an active product that meets ROHS3 standards. Packaging differs (standard vs. bulk), but electrical and mechanical specifications are identical.

Q: Why is the 8230-76 classified as obsolete?

A: Obsolescence typically reflects discontinuation of production by the manufacturer. The active 8230-76-RC variant ensures continued component availability and compliance with modern regulatory requirements.

Q: Are there any compatibility concerns when substituting the 8230-76-RC for the 8230-76?

A: No compatibility concerns exist. The components share identical electrical characteristics, tolerance specifications, frequency response, and physical dimensions. Through-hole axial mounting is identical, and both operate across the same temperature range (-55°C to 105°C).

Q: What packaging options are available?

A: The 8230-76 is supplied in standard packaging. The 8230-76-RC is available in bulk packaging. Both contain the same component; packaging selection depends on procurement volume and handling requirements.

Q: Is RoHS compliance a critical factor for component selection?

A: RoHS compliance is mandatory for products sold into regulated markets and is increasingly required by OEMs and contract manufacturers. The 8230-76-RC's ROHS3 compliance ensures compatibility with modern supply chain requirements and environmental regulations.
