Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4426-2NC is determined by strict alignment of the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 5 nH with ±10% tolerance
• Core material: Air (unshielded wirewound construction)
• Q factor @ 150 MHz: 140
• Self-resonant frequency: 3 GHz
• Inductance test frequency: 150 MHz

Mechanical Compatibility Criteria:

• Mounting type: Surface Mount
• Package classification: Nonstandard
• Moisture sensitivity level: 1 (Unlimited)

Functional Operating Criteria:

• Current rating must equal or exceed 3 A
• Operating temperature range must encompass or exceed -55°C to 125°C

The substitute part AIAC-1512C-5N0K-T from Abracon LLC satisfies all electrical equivalence criteria and mechanical compatibility requirements. The substitute demonstrates superior current rating (4.6 A versus 3 A) and maintains identical inductance, tolerance, Q factor, and self-resonant frequency specifications. Physical dimensions differ slightly, and operating temperature range is -40°C to 125°C, which covers the upper operational envelope of the original part.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (4426-2NC): The 4426-2NC remains the specified component for applications requiring the full operating temperature range of -55°C to 125°C. This part is Active status with established supply (987 pcs in stock). Selection is appropriate for designs already qualified to this component and where the lower temperature limit of -55°C is a functional requirement.

Substitute Selection (AIAC-1512C-5N0K-T): The AIAC-1512C-5N0K-T is suitable for applications where the operating temperature range of -40°C to 125°C satisfies system requirements. This substitute offers superior current rating margin (4.6 A versus 3 A), ROHS3 compliance status, and specified DC resistance of 1.5 mOhm maximum. Inventory availability is higher (1921 pcs in stock). Selection is appropriate for new designs or redesigns where the -40°C lower temperature limit is acceptable and regulatory compliance is a design criterion.

Compliance Consideration: The substitute part demonstrates ROHS3 compliance, whereas the original part is RoHS non-compliant. This distinction is material for applications subject to regulatory requirements or customer specifications mandating RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the AIAC-1512C-5N0K-T directly replace the 4426-2NC in existing designs?

A: Electrical substitution is valid when the operating temperature range of -40°C to 125°C encompasses the application's thermal requirements. The inductance value, tolerance, Q factor, and self-resonant frequency are identical. Physical dimensions differ slightly (0.130" L x 0.098" W versus 0.145" L x 0.120" W), requiring PCB layout verification. DC resistance specification (1.5 mOhm max) is provided for the substitute but not specified for the original part.

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

A: The primary differences are: (1) current rating—4.6 A for the substitute versus 3 A for the original; (2) operating temperature lower limit—-40°C for the substitute versus -55°C for the original; (3) physical dimensions—the substitute is slightly smaller; (4) RoHS compliance—the substitute is ROHS3 compliant while the original is non-compliant; (5) DC resistance—specified for the substitute (1.5 mOhm max) but not provided for the original.

Q: Are there any frequency-dependent performance differences?

A: No. Both inductors demonstrate identical Q factor of 140 at 150 MHz and identical self-resonant frequency of 3 GHz. Inductance test frequency is 150 MHz for both parts.

Q: What is the impact of the different physical dimensions?

A: The AIAC-1512C-5N0K-T is physically smaller (0.130" L x 0.098" W x 0.110" H versus 0.145" L x 0.120" W x 0.125" H). PCB footprint and component placement must be verified for compatibility with existing circuit board designs. The smaller package may provide layout advantages in space-constrained applications.

Q: Does the higher current rating of the substitute affect circuit performance?

A: The higher current rating (4.6 A versus 3 A) provides additional thermal margin and does not negatively affect circuit performance. The substitute is suitable for applications rated at 3 A or lower. Applications requiring the full 4.6 A rating benefit from the increased current capacity.

Q: What is the significance of the DC resistance specification?

A: The substitute provides a specified maximum DC resistance of 1.5 mOhm, which enables precise power loss calculations in high-current applications. The original part does not provide this specification. For applications where DCR is critical to performance, the substitute's specified value provides design certainty.

Q: Are both parts suitable for high-frequency applications?

A: Yes. Both inductors are designed for high-frequency operation with self-resonant frequency of 3 GHz and Q factor of 140 at 150 MHz. Both are appropriate for RF and microwave circuit applications within their respective operating temperature ranges.
