Key Parameters

Substitute Part Grouping Explanation

Substitution of the 79F5R6K-RC is based on the following critical parameters:

• Inductance Value: Must remain 5.6 µH with ±10% tolerance
• Core Type & Shielding: Ferrite material, unshielded configuration
• Mounting Configuration: Through-hole axial package
• Operating Temperature Range: -55°C to 105°C minimum
• Current Handling Capability: Substitute must support at least 180 mA operation
• DC Resistance: Should not exceed 1.9Ohm to maintain circuit performance

The 8230-38-RC qualifies as a direct substitute based on matching inductance, core material, shielding type, mounting style, and temperature range. The substitute provides enhanced current rating (260 mA) and improved DC resistance (1.8Ohm), making it suitable for applications requiring the original 79F5R6K-RC specifications.

Parameter Comparison

Engineering Selection Recommendations

The 8230-38-RC is the qualified substitute for the obsolete 79F5R6K-RC. Both components are manufactured by Bourns Inc. and maintain identical ROHS3 and REACH compliance certifications. The substitute meets all electrical specifications required by the original part while providing superior performance characteristics: increased current rating capacity (260 mA versus 180 mA) and reduced DC resistance (1.8Ohm versus 1.9Ohm maximum). Both parts operate within the same temperature range and maintain equivalent inductance values with matching tolerance specifications. The 8230-38-RC is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 8230-38-RC directly replace the 79F5R6K-RC in existing designs?

A: Yes. Both inductors share identical inductance (5.6 µH), tolerance (±10%), core material (ferrite), shielding configuration (unshielded), mounting type (through-hole axial), and operating temperature range (-55°C to 105°C). The substitute meets or exceeds all electrical requirements of the original part.

Q: What are the physical dimension differences between these parts?

A: The 79F5R6K-RC measures 0.100" diameter × 0.160" length (2.54mm × 4.06mm). The 8230-38-RC measures 0.120" diameter × 0.300" length (3.05mm × 7.62mm). Physical layout considerations may apply in space-constrained applications.

Q: Are there compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status. Both are classified under ECCN EAR99 and HTSUS 8504.50.4000.

Q: Why does the 8230-38-RC have higher current rating and lower DC resistance?

A: The 8230-38-RC represents a newer design iteration within the Bourns inductor product line, incorporating improved core geometry and winding configuration that deliver enhanced electrical performance while maintaining the same inductance value and core material specifications.

Q: Is the 8230-38-RC suitable for applications originally designed for 180 mA operation?

A: Yes. The 8230-38-RC is rated for 260 mA maximum current, exceeding the original 180 mA requirement. The reduced DC resistance (1.8Ohm versus 1.9Ohm) provides improved efficiency in the original operating range.
