Key Parameters

Substitute Part Grouping Explanation

Substitution of the AISC-0402F-R13M-T is evaluated based on the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 0402 (1005 Metric) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Inductance Value: The substitute AIMC-0402-R12J-T provides 120 nH inductance, which falls within the tolerance band of the original 130 nH specification (±20% tolerance = 104 nH to 156 nH range). This inductance value is functionally equivalent for circuit applications.

Current Rating Consideration: The substitute part is rated for 150 mA continuous current, which is lower than the original 640 mA rating. This represents a significant derating and limits substitution to applications where the actual circuit current requirement does not exceed 150 mA.

DC Resistance: The substitute exhibits 2.8 Ohm maximum DC resistance compared to the original 230 mOhm. This higher resistance value affects power dissipation characteristics and must be evaluated against circuit requirements.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Parameter Comparison

Engineering Selection Recommendations

The AIMC-0402-R12J-T is an active product from the same manufacturer, providing supply continuity for the obsolete AISC-0402F-R13M-T. Both components maintain identical regulatory compliance certifications (ROHS3, REACH unaffected, MSL 1), ensuring compatibility with current manufacturing standards and environmental requirements.

Selection of the AIMC-0402-R12J-T as a substitute requires verification that the application circuit operates within the 150 mA current limit. The inductance value of 120 nH is within the ±20% tolerance specification of the original 130 nH part and is suitable for circuits designed to accept this tolerance band.

The higher DC resistance of the substitute (2.8 Ohm versus 230 mOhm) represents a material difference in power dissipation characteristics. Applications sensitive to inductor losses or thermal performance must account for this parameter difference in circuit analysis.

The substitute part operates across a wider temperature range (-55°C to 125°C) compared to the original (-40°C to 85°C), providing additional thermal margin for applications requiring extended operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the AIMC-0402-R12J-T directly replace the AISC-0402F-R13M-T in all applications?

A: Direct replacement is limited by current rating. The substitute is rated for 150 mA maximum, while the original supports 640 mA. Substitution is valid only for circuits where actual operating current does not exceed 150 mA.

Q: What is the inductance tolerance impact of using the substitute part?

A: The original part specifies ±20% tolerance (104 nH to 156 nH range). The substitute provides 120 nH with ±5% tolerance (114 nH to 126 nH range). The 120 nH value falls within the original tolerance band and is functionally equivalent for circuits designed to accept ±20% inductance variation.

Q: How does the DC resistance difference affect circuit performance?

A: The substitute exhibits 2.8 Ohm DC resistance compared to 230 mOhm in the original. This 12-fold increase in resistance results in higher power dissipation and heat generation. Applications with strict power budget or thermal constraints must evaluate this parameter against circuit requirements.

Q: Are both parts compatible with the same PCB assembly process?

A: Yes. Both components use identical 0402 (1005 Metric) surface mount packaging with the same footprint dimensions and mounting type, ensuring compatibility with existing PCB layouts and automated assembly equipment.

Q: What is the difference between drum core wirewound and multilayer inductor construction?

A: The original uses ferrite drum core wirewound construction, while the substitute uses ceramic multilayer construction. These represent different manufacturing technologies with different electrical characteristics. The substitute exhibits lower self-resonant frequency (600 MHz versus 1 GHz) and different Q factor performance.

Q: Do both parts meet current environmental and regulatory requirements?

A: Yes. Both the AISC-0402F-R13M-T and AIMC-0402-R12J-T are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings, meeting current manufacturing and environmental standards.

Q: What is the availability status of each part?

A: The AISC-0402F-R13M-T is classified as obsolete with 858 pieces in current inventory. The AIMC-0402-R12J-T is an active product with 990 pieces in inventory, providing ongoing supply availability for new designs and production requirements.
