Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4426-2RC is determined by strict equivalence across the following critical parameters:

• Inductance Value: 5 nH (±10% tolerance maintained)
• Core Type: Air core wirewound construction
• Shielding Configuration: Unshielded
• Frequency Characteristics: Q factor of 140 @ 150 MHz and self-resonant frequency of 3 GHz
• Mounting Technology: Surface mount configuration
• Current Handling: Minimum 3 A rating required

The AIAC-1512C-5N0K-T from Abracon LLC meets all substitution criteria. This part maintains identical inductance, core material, shielding, and frequency performance while providing enhanced current capacity (4.6 A) and specified DC resistance (1.5 mOhm max).

Engineering Selection Recommendations

The AIAC-1512C-5N0K-T is a direct functional equivalent for the obsolete 4426-2RC. Selection should be based on the following factors:

Product Status: The 4426-2RC is obsolete, while the AIAC-1512C-5N0K-T is active and in production, ensuring long-term availability and supply chain continuity.

Compliance Requirements: The AIAC-1512C-5N0K-T is ROHS3 compliant, whereas the 4426-2RC is non-compliant. Applications subject to RoHS regulations require the Abracon substitute.

Electrical Performance: Both parts deliver identical inductance, Q factor, and self-resonant frequency performance. The Abracon part provides higher current capacity (4.6 A versus 3 A), offering design margin in current-limited applications.

Temperature Range: The 4426-2RC operates from -55°C to 125°C, while the AIAC-1512C-5N0K-T operates from -40°C to 125°C. Applications requiring operation below -40°C must retain the original part or identify alternative solutions.

Physical Dimensions: Both parts use nonstandard packages with similar footprints (4426-2RC: 3.68mm × 3.05mm; AIAC-1512C-5N0K-T: 3.30mm × 2.50mm), suitable for most PCB layouts with minor adjustments.

Frequently Asked Questions (FAQ)

Q: Can the AIAC-1512C-5N0K-T replace the 4426-2RC in all applications?

A: The AIAC-1512C-5N0K-T is electrically and mechanically equivalent for applications operating within -40°C to 125°C. Applications requiring operation below -40°C require the original 4426-2RC or alternative sourcing.

Q: What is the significance of the higher current rating on the substitute part?

A: The AIAC-1512C-5N0K-T is rated for 4.6 A versus the 4426-2RC's 3 A rating. This provides additional design margin and allows the substitute to handle higher current loads without saturation or thermal stress.

Q: Are there packaging differences between these parts?

A: Both parts use nonstandard surface mount packages. The AIAC-1512C-5N0K-T is slightly smaller (3.30mm × 2.50mm versus 3.68mm × 3.05mm) and is supplied in Tape & Reel packaging, while the 4426-2RC packaging format is not specified.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance is a material composition requirement and does not alter the electrical characteristics of the inductor. The AIAC-1512C-5N0K-T maintains identical inductance, Q factor, and frequency response.

Q: What is the DC resistance specification for the 4426-2RC?

A: The DC resistance for the 4426-2RC is not specified in available documentation. The AIAC-1512C-5N0K-T specifies 1.5 mOhm maximum, which may be used as a reference for circuit design calculations.
