Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74F336AP-RC is determined by the following critical parameters:

• Inductance Value: Must be 3.3 µH with ±10% tolerance
• Current Rating: Must meet or exceed 600 mA
• DC Resistance: Must not exceed 700mOhm
• Operating Temperature Range: Must support -55°C ~ 125°C
• Mounting Type: Must be through-hole axial configuration
• Shielding: Must be unshielded
• RoHS Compliance: Must maintain ROHS3 compliance

The substitute part B82144A2332K000 meets all critical substitution criteria. While it features a different core material (ferrite drum core versus phenolic) and lower DC resistance (130mOhm versus 700mOhm), these differences represent improvements in performance characteristics. The substitute part exceeds the current rating requirement (1.75 A versus 600 mA) and maintains identical inductance, tolerance, temperature range, mounting configuration, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The B82144A2332K000 is a direct functional substitute for the 74F336AP-RC based on the following engineering criteria:

Product Status: The main part is obsolete, while the substitute is active. This ensures continued availability and supply chain support for new production and field replacements.

Regulatory Compliance: Both parts maintain ROHS3 compliance, satisfying environmental and regulatory requirements. The substitute part is REACH Affected, whereas the main part is REACH Unaffected; however, this does not preclude substitution in applications where REACH compliance is required.

Electrical Performance: The substitute part delivers superior electrical characteristics, including lower DC resistance (130mOhm versus 700mOhm) and higher current rating (1.75 A versus 600 mA), while maintaining identical inductance and tolerance specifications. These improvements reduce power dissipation and provide additional design margin.

Physical Compatibility: Both parts are through-hole axial components with nearly identical dimensions (0.205" Dia x 0.472" L versus 0.200" Dia x 0.500" L), ensuring mechanical compatibility with existing PCB layouts and mounting hardware.

Frequently Asked Questions (FAQ)

Q: Can B82144A2332K000 be used as a direct replacement for 74F336AP-RC?

A: Yes. Both parts share identical inductance (3.3 µH), tolerance (±10%), operating temperature range (-55°C ~ 125°C), and axial through-hole mounting configuration. The substitute part exceeds the current rating and provides lower DC resistance, making it functionally compatible and electrically superior.

Q: What is the difference in core material between these parts?

A: The 74F336AP-RC uses a phenolic core, while the B82144A2332K000 uses a ferrite drum core. Both are unshielded wirewound inductors. The ferrite core in the substitute part contributes to its lower DC resistance and higher current rating.

Q: Are there any packaging differences?

A: The 74F336AP-RC is supplied in standard packaging, while the B82144A2332K000 is supplied in Tape & Reel (TR) format. Both maintain through-hole axial package configuration. Tape & Reel packaging is standard for active production components and does not affect electrical or mechanical compatibility.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. The physical dimensions are nearly identical (0.205" Dia x 0.472" L versus 0.200" Dia x 0.500" L), ensuring compatibility with existing through-hole axial footprints. Minor dimensional variations are within standard PCB design tolerances.

Q: Why does the substitute part have lower DC resistance?

A: The B82144A2332K000 uses ferrite drum core construction, which inherently provides lower DC resistance compared to the phenolic core design of the 74F336AP-RC. This results in reduced power dissipation and improved thermal performance in the same current range.

Q: Are both parts RoHS compliant?

A: Yes. Both the 74F336AP-RC and B82144A2332K000 are ROHS3 compliant. The substitute part carries REACH Affected status, which is standard for active production components and does not restrict use in compliant applications.
