Key Parameters

Substitute Part Grouping Explanation

Substitution of the AISC-0402F-R13K-T is determined by 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 on printed circuit boards.

Inductance Value: The substitute part must provide an inductance value within the functional range of the original specification. The AISC-0402F-R13K-T operates at 130 nH; substitute parts with inductance values of 120 nH to 130 nH fall within acceptable tolerance bands for most circuit applications.

Current Handling Capability: The substitute must support the required current load. The original part is rated for 640 mA; substitute parts with lower current ratings require circuit-level evaluation.

DC Resistance: The substitute's DC resistance directly impacts circuit performance and power dissipation. The original part specifies 230 mOhm maximum; substitutes with significantly higher resistance values alter circuit behavior.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and MSL 1 rating to ensure manufacturing process compatibility and long-term reliability.

Operating Temperature Range: The substitute must support the required operating temperature envelope. The original part operates from -40°C to 85°C; substitutes with narrower temperature ranges may not be suitable for all applications.

Parameter Comparison

Engineering Selection Recommendations

The AIMC-0402-R12J-T is an active product from Abracon LLC that shares the same 0402 (1005 Metric) package footprint and unshielded configuration as the obsolete AISC-0402F-R13K-T. Both components maintain ROHS3 compliance and MSL 1 ratings, ensuring compatibility with standard manufacturing processes.

The substitute part provides a narrower inductance tolerance (±5% versus ±10%), which may improve circuit performance in applications requiring tighter inductance specifications. The extended operating temperature range (-55°C to 125°C) of the substitute accommodates a broader set of environmental conditions compared to the original part's -40°C to 85°C range.

Critical differences exist in current handling and DC resistance characteristics. The AIMC-0402-R12J-T is rated for 150 mA maximum current, substantially lower than the original part's 640 mA rating. Additionally, the substitute exhibits significantly higher DC resistance at 2.8 Ohm maximum compared to the original 230 mOhm specification. These differences necessitate circuit-level analysis to determine suitability for applications requiring high current delivery or minimal resistive losses.

The substitute employs a multilayer ceramic core construction, whereas the original uses a ferrite drum core wirewound design. This structural difference affects frequency response characteristics and electromagnetic behavior in the circuit.

Frequently Asked Questions (FAQ)

Q: Can the AIMC-0402-R12J-T directly replace the AISC-0402F-R13K-T in all applications?

A: Direct replacement is not universal. Both parts share the same 0402 package and unshielded configuration, enabling mechanical compatibility. However, the substitute's 150 mA current rating is significantly lower than the original 640 mA rating, and its 2.8 Ohm DC resistance is substantially higher than the original 230 mOhm specification. Applications requiring high current delivery or minimal resistive losses must evaluate circuit performance with the substitute's electrical characteristics.

Q: What is the inductance difference between these parts?

A: The AISC-0402F-R13K-T provides 130 nH inductance with ±10% tolerance, while the AIMC-0402-R12J-T provides 120 nH inductance with ±5% tolerance. The 10 nH difference represents approximately 7.7% variation. The substitute's tighter tolerance may provide improved circuit performance in applications sensitive to inductance variation.

Q: Are both parts suitable for the same temperature operating range?

A: No. The original part operates from -40°C to 85°C, while the substitute operates from -55°C to 125°C. The substitute supports a wider temperature envelope, making it suitable for applications requiring extended low-temperature operation or elevated temperature environments beyond the original part's specification.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the AISC-0402F-R13K-T and AIMC-0402-R12J-T are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both parts are REACH unaffected and classified under ECCN EAR99 and HTSUS 8504.50.8000, ensuring equivalent regulatory standing for procurement and manufacturing processes.

Q: What is the primary reason for substitution?

A: The AISC-0402F-R13K-T is classified as obsolete, making it unavailable for new procurement. The AIMC-0402-R12J-T is an active product from the same manufacturer, ensuring ongoing availability and supply chain continuity for designs requiring 0402 package inductors in the 120-130 nH range.

Q: How do the core materials differ between these parts?

A: The original part uses a ferrite drum core with wirewound construction, while the substitute uses a multilayer ceramic core. These different core materials result in different frequency response characteristics, Q-factor performance, and electromagnetic behavior. Circuit applications sensitive to frequency-dependent inductor behavior should evaluate both designs.
