Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4426R-4RC is determined by the following critical parameters:

• Inductance Value: 12.5 nH with ±5% tolerance
• Inductance Tolerance: ±5%
• Core Type: Air core wirewound construction
• Shielding Configuration: Unshielded
• Mounting Technology: Surface mount
• Frequency Characteristics: Q factor of 137 @ 150 MHz and self-resonant frequency of 3 GHz
• Current Handling: Minimum 3 A rating required
• Environmental Compliance: ROHS3 and REACH compliance

The AIAC-1512C-12N5J-T from Abracon LLC meets all substitution criteria with identical inductance, tolerance, core material, shielding, and frequency characteristics. The substitute part exceeds the current rating requirement at 4.3 A and maintains equivalent electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The AIAC-1512C-12N5J-T is a direct functional equivalent to the 4426R-4RC. Both components share identical inductance specifications, tolerance, core construction, and frequency characteristics. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The AIAC-1512C-12N5J-T provides superior current handling capability at 4.3 A compared to the original 3 A rating, offering additional design margin without compromising electrical performance. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification.

Physical dimensions differ slightly between the two parts. The substitute measures 0.130" L × 0.098" W × 0.110" H (3.30mm × 2.50mm × 2.80mm) compared to the original 0.145" L × 0.125" W × 0.120" H (3.68mm × 3.18mm × 3.05mm). PCB layout verification is required to confirm mechanical compatibility.
