4426R-2RC Equivalent and Substitute Parts

Part Overview

The 4426R-2RC is a 5 nH unshielded wirewound inductor manufactured by API Delevan Inc., rated for 3 A continuous current operation. This surface-mount component is classified as obsolete. Locating equivalent or substitute parts is necessary due to the product's obsolete status, requiring engineers to identify compatible alternatives that maintain the same electrical and mechanical performance characteristics within the allowable tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

The AIAC-1512C-5N0K-T qualifies as a substitute based on the following strictly matched parameters:

Electrical Parameters (Critical for Substitution):

• Inductance: 5 nH (identical)
• Inductance Tolerance: ±10% (identical)
• Q @ Frequency: 140 @ 150 MHz (identical)
• Self Resonant Frequency: 3 GHz (identical)
• Current Rating: 4.6 A (exceeds the 3 A requirement)
• Type: Wirewound (identical)
• Core Material: Air (identical)
• Shielding: Unshielded (identical)

Mechanical Parameters (Critical for Substitution):

• Mounting Type: Surface Mount (identical)
• Package / Case: Nonstandard (identical)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• REACH Status: REACH Unaffected (identical)

The substitute part's higher current rating (4.6 A vs. 3 A) does not restrict substitution; it provides additional design margin. Dimensional differences are within acceptable variation for nonstandard packages in this inductance class.

Parameter Comparison

Engineering Selection Recommendations

The AIAC-1512C-5N0K-T is a suitable substitute for the 4426R-2RC based on the following factors:

Compliance and Certifications: Both parts carry identical ROHS3 compliance, MSL rating, and REACH status, ensuring regulatory acceptance in equivalent applications.

Product Status: The 4426R-2RC is obsolete. The AIAC-1512C-5N0K-T is active, providing reliable sourcing for new designs or end-of-life replacements.

Electrical Performance: Identical inductance, tolerance, quality factor, and resonant frequency ensure direct functional equivalence in RF and high-frequency circuit applications.

Current Capacity: The substitute's 4.6 A rating exceeds the original 3 A requirement, eliminating risk from thermal stress in equivalent or reduced-current applications.

Temperature Consideration: The substitute's operating range narrows to -40°C minimum compared to -55°C for the original. This restriction applies only to designs requiring operation below -40°C.

Frequently Asked Questions (FAQ)

Q: Can the AIAC-1512C-5N0K-T replace the 4426R-2RC in a direct board-level substitution?

A: Yes. Both parts share identical inductance, tolerance, quality factor, and resonant frequency specifications. Mechanical compatibility exists for nonstandard surface-mount packages. Verify board layout accommodates the slightly smaller dimensions of the substitute (3.30mm x 2.50mm vs. 3.68mm x 3.18mm).

Q: Does the higher current rating of the substitute present any concerns?

A: No. A higher current rating provides additional design margin and does not negatively impact circuit performance. The part remains suitable for applications requiring 3 A or less.

Q: Is the operating temperature difference significant for substitution?

A: The substitute operates from -40°C to 125°C versus the original's -55°C to 125°C. This substitution is fully compatible for applications within the -40°C to 125°C range. Applications requiring operation below -40°C require alternative selection.

Q: How do the physical dimensions affect substitution?

A: The substitute is slightly smaller (3.30mm x 2.50mm x 2.80mm seated height vs. 3.68mm x 3.18mm x 3.05mm). Verify PCB footprint and component placement clearances accommodate these reduced dimensions.

Q: Does the DC resistance specification of the substitute matter for substitution?

A: The DC resistance specification provided for the substitute (1.5 mOhm Max) does not represent a substitution restriction, as the original part does not specify this parameter. The substitute's DCR is suitable for low-loss RF applications typical of 5 nH inductors.

Q: Are both parts RoHS compliant?

A: Yes. Both the 4426R-2RC and AIAC-1512C-5N0K-T carry ROHS3 compliance and identical moisture sensitivity and REACH classifications, ensuring equivalent regulatory status.
