Engineering Selection Recommendations

AISC-1008F-1R2G-T (Abracon LLC) - Direct Equivalent:

The AISC-1008F-1R2G-T is classified as a direct manufacturer substitute. This part maintains identical inductance value (1.2 µH) and package configuration (1008 / 2520 Metric) as the 1008HC-122EKFS. The AISC-1008F-1R2G-T offers superior current rating (650 mA versus 550 mA) and tighter inductance tolerance (±2% versus ±10%), providing enhanced performance margin. Both parts operate within the same temperature range (-40°C to 85°C) and maintain ROHS3 compliance with unlimited moisture sensitivity rating. The part is currently in active production status with established supply chain availability.

PM1008-1R2K-RC (Bourns Inc.) - Similar Specification:

The PM1008-1R2K-RC is classified as a similar specification part. While maintaining the 1.2 µH inductance value and 1008 package type, this part exhibits significantly different electrical characteristics. The DC resistance is substantially higher (2 Ohm versus 400 mOhm), and the current rating is lower (280 mA versus 550 mA). The PM1008-1R2K-RC supports an extended operating temperature range (-40°C to 125°C) and is in active production. This part is suitable only for applications where the lower current rating and higher DC resistance are acceptable design parameters.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the AISC-1008F-1R2G-T directly replace the 1008HC-122EKFS in existing designs?

A: The AISC-1008F-1R2G-T maintains identical inductance value, package type, and core material specifications. The higher current rating (650 mA) and tighter tolerance (±2%) provide equivalent or improved performance. Direct substitution is supported by matching electrical and mechanical parameters.

Q: What are the key differences between the AISC-1008F-1R2G-T and PM1008-1R2K-RC?

A: The AISC-1008F-1R2G-T maintains DC resistance of 800 mOhm with 650 mA current rating. The PM1008-1R2K-RC has significantly higher DC resistance (2 Ohm) and lower current rating (280 mA). Selection depends on circuit requirements for current handling and resistive losses.

Q: Is the PM1008-1R2K-RC suitable as a substitute for the 1008HC-122EKFS?

A: The PM1008-1R2K-RC shares the same inductance value and package type but differs substantially in current rating and DC resistance. This part is suitable only for applications where the 280 mA current limit and 2 Ohm resistance are compatible with circuit design specifications.

Q: What is the significance of the inductance tolerance difference between these parts?

A: The 1008HC-122EKFS and PM1008-1R2K-RC specify ±10% tolerance, while the AISC-1008F-1R2G-T specifies ±2% tolerance. Tighter tolerance provides more precise inductance values, beneficial for applications requiring strict frequency response or impedance matching characteristics.

Q: Are all substitute parts available in the same packaging format?

A: The 1008HC-122EKFS packaging is not specified. The AISC-1008F-1R2G-T and PM1008-1R2K-RC are both supplied in Tape & Reel (TR) format, standard for surface mount production environments.

Q: Do the substitute parts support the same operating temperature range?

A: The 1008HC-122EKFS and AISC-1008F-1R2G-T both operate from -40°C to 85°C. The PM1008-1R2K-RC supports an extended range of -40°C to 125°C, providing additional thermal margin for high-temperature applications.

Q: What compliance certifications apply to all listed parts?

A: All parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing standards and environmental regulations.
