Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74F226AP-RC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH (exact match required)
• Mounting type: Through hole axial configuration
• Operating temperature range: -55°C to 125°C minimum
• Shielding classification: Unshielded

Secondary Compatibility Factors:

• Current rating: Substitute must equal or exceed 800 mA
• DC resistance: Substitute must not exceed 300mOhm to maintain circuit performance
• Package dimensions: Physical compatibility with existing PCB layouts
• Regulatory compliance: ROHS3 certification required

The B82144A2222K000 qualifies as a substitute part. It maintains the identical inductance value of 2.2 µH, operates within the required temperature range, and provides superior current handling capability (1.9 A versus 800 mA). The substitute features lower DC resistance (110mOhm Max versus 300mOhm Max), which reduces power dissipation. Both components are unshielded through-hole axial inductors with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The B82144A2222K000 is an active product with current manufacturing status, providing supply chain continuity for applications requiring 2.2 µH inductors in through-hole axial configuration. Both the original 74F226AP-RC and substitute part maintain ROHS3 compliance and operate across identical temperature ranges.

The substitute part demonstrates improved electrical characteristics: current rating of 1.9 A provides 137% margin above the original 800 mA specification, and DC resistance of 110mOhm Max is 63% lower than the original 300mOhm Max specification. These improvements reduce thermal stress and power dissipation in the inductor during operation.

Physical dimensions are comparable (0.205" Dia x 0.472" L for substitute versus 0.200" Dia x 0.500" L for original), supporting direct PCB layout compatibility in most applications. The substitute's ±10% inductance tolerance is tighter than the original ±20%, providing improved circuit performance predictability.

Frequently Asked Questions (FAQ)

Q: Can the B82144A2222K000 directly replace the 74F226AP-RC in existing designs?

A: Yes. Both components share identical inductance values (2.2 µH), unshielded configuration, through-hole axial mounting, and operating temperature range (-55°C to 125°C). Physical dimensions are comparable, supporting direct PCB compatibility. The substitute's superior current rating and lower DC resistance provide performance benefits without circuit redesign.

Q: What are the key differences between these two inductors?

A: The primary differences are core material (phenolic versus ferrite drum core), current rating (800 mA versus 1.9 A), DC resistance (300mOhm Max versus 110mOhm Max), and inductance tolerance (±20% versus ±10%). The substitute offers improved electrical performance with lower losses and higher current capacity.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts maintain ROHS3 compliance and operate within identical temperature specifications. The substitute is an active product with current manufacturing support, whereas the original is obsolete. No compliance barriers exist for substitution.

Q: How do the physical dimensions compare?

A: Original dimensions are 0.200" Dia x 0.500" L (5.08mm x 12.70mm). Substitute dimensions are 0.205" Dia x 0.472" L (5.20mm x 12.00mm). The differences are minimal and typically accommodate standard through-hole PCB layouts without modification.

Q: What is the impact of lower DC resistance in the substitute part?

A: Lower DC resistance (110mOhm Max versus 300mOhm Max) reduces resistive power dissipation, lowering operating temperature and improving efficiency. This is a beneficial characteristic for circuit performance and component reliability.
