Substitute Part Grouping Explanation

Substitution eligibility for the CS321613-100K is determined by the following critical parameters:

  • Inductance value: 10 µH (exact match required)
  • Tolerance: ±10% (matching tolerance specification)
  • Current rating: 25 mA minimum (equal or higher acceptable)
  • Package / Case: 1206 (3216 Metric) (exact match required for PCB compatibility)
  • Shielding: Shielded (required for EMI performance)
  • Core material: Ferrite (required for frequency response characteristics)
  • Operating temperature range: -55°C ~ 125°C (minimum requirement)
  • RoHS compliance: ROHS3 Compliant (regulatory requirement)

The AIML-1206-100K-T from Abracon LLC meets all substitution criteria. While the DC resistance specification is slightly higher (800 mOhm Max versus 700 mOhm Max), this remains within acceptable tolerance for equivalent functionality in the specified application class.

Engineering Selection Recommendations

The AIML-1206-100K-T is a direct substitute for the obsolete CS321613-100K. Both components are ROHS3 compliant and maintain identical electrical specifications for inductance, tolerance, current rating, and operating temperature range. The substitute part is currently in active production status with substantial inventory availability (19,940 Pcs), ensuring supply chain continuity.

The DC resistance differential of 100 mOhm (800 mOhm versus 700 mOhm) represents a 14.3% increase and must be evaluated within the context of the specific circuit application. For applications where DCR is a critical design parameter, this variance should be verified against circuit performance requirements. The higher self-resonant frequency (28 MHz versus 24 MHz) of the substitute part may provide improved high-frequency performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the AIML-1206-100K-T be used as a direct replacement for the CS321613-100K?

A: Yes. Both components share identical inductance (10 µH), tolerance (±10%), current rating (25 mA), package form factor (1206), shielding type, core material, operating temperature range, and RoHS compliance status. The substitute part is electrically and mechanically compatible for PCB assembly.

Q: What is the significance of the DC resistance difference?

A: The AIML-1206-100K-T has a maximum DC resistance of 800 mOhm compared to 700 mOhm for the CS321613-100K. This 100 mOhm difference may affect power dissipation and voltage drop characteristics in circuits where DCR is a design constraint. Circuit validation is necessary if DCR performance is critical to application function.

Q: Are there packaging differences between these parts?

A: Both components use identical 1206 (3216 Metric) surface mount packaging with compatible footprints. The AIML-1206-100K-T is supplied in Tape & Reel (TR) format, which is standard for production assembly processes.

Q: What is the product status difference, and does it matter?

A: The CS321613-100K is obsolete, while the AIML-1206-100K-T is active production. The substitute part has confirmed long-term availability and supply chain support, making it the appropriate choice for new designs and ongoing production requirements.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the CS321613-100K and AIML-1206-100K-T are ROHS3 compliant. The substitute part also carries REACH Unaffected status, confirming compliance with additional regulatory frameworks.
