Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4426R-2 is determined by the following critical parameters:

Electrical Equivalence Criteria:

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

Mechanical Compatibility Criteria:

• Mounting type: Surface mount
• Package classification: Nonstandard
• Tape & Reel packaging format

Environmental & Compliance Criteria:

• Operating temperature range: Must encompass or exceed -55°C to 125°C
• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

The AIAC-1512C-5N0K-T from Abracon LLC meets all electrical equivalence criteria and maintains mechanical compatibility. The substitute part demonstrates identical inductance, tolerance, Q factor, and self resonant frequency specifications. Current rating is higher (4.6 A versus 3 A), which does not restrict substitution in applications requiring 3 A or less. Operating temperature range is -40°C to 125°C, which covers the upper operating envelope of the original part.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 4426R-2

The 4426R-2 remains the specified component when the full operating temperature range of -55°C to 125°C is required. This part is in active production status with established supply chain availability (626 units in stock). ROHS3 compliance and unlimited moisture sensitivity rating support deployment in standard manufacturing environments.

Substitute Part: AIAC-1512C-5N0K-T

The AIAC-1512C-5N0K-T from Abracon LLC is electrically and mechanically equivalent for applications operating within the -40°C to 125°C temperature range. This substitute provides higher current rating capacity (4.6 A versus 3 A), which does not compromise circuit performance in designs requiring 3 A or less. The substitute part carries ROHS3 compliance and MSL 1 rating, matching environmental qualification requirements. Higher inventory availability (1921 units in stock) may support procurement timelines. The substitute includes specified DC resistance (1.5 mOhm Max), providing additional design documentation compared to the primary part.

Selection Criteria:

• Use 4426R-2 when extended low-temperature operation below -40°C is required
• Use AIAC-1512C-5N0K-T when operating temperature range is -40°C to 125°C and higher current margin is acceptable
• Both parts are suitable for surface mount assembly in Tape & Reel format
• Both parts maintain identical electrical performance at 150 MHz test frequency

Frequently Asked Questions (FAQ)

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

A: The AIAC-1512C-5N0K-T is electrically and mechanically equivalent for applications operating within -40°C to 125°C. If your circuit operates below -40°C, the 4426R-2 is required due to its extended temperature rating to -55°C.

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 continuous current versus 3 A on the 4426R-2. This higher rating does not affect substitution for designs requiring 3 A or less. The substitute provides additional thermal margin in current-limited applications.

Q: Are the physical dimensions compatible between these parts?

A: Both parts are surface mount components in nonstandard packages. The 4426R-2 measures 0.145" L x 0.120" W x 0.125" H (max seated height). The AIAC-1512C-5N0K-T measures 0.130" L x 0.098" W x 0.110" H (max seated height). The substitute is slightly smaller. Verify PCB footprint compatibility before substitution.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the 4426R-2 and AIAC-1512C-5N0K-T are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8504.50.8000.

Q: What is the difference in DC resistance between these parts?

A: The 4426R-2 does not specify DC resistance in the datasheet. The AIAC-1512C-5N0K-T specifies 1.5 mOhm maximum DC resistance. For applications where DCR is critical, obtain the 4426R-2 DCR specification from the manufacturer or use the substitute with known DCR characteristics.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the 4426R-2 and AIAC-1512C-5N0K-T are supplied in Tape & Reel (TR) format, suitable for automated surface mount assembly processes.

Q: What is the Q factor significance at 150 MHz?

A: Both parts maintain Q = 140 at 150 MHz, indicating equivalent high-frequency performance and low loss characteristics. This parameter is critical for RF and microwave circuit applications where signal integrity depends on inductor quality factor.
