Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS321613-5R6K is determined by the following critical parameters:

• Inductance Value: Must be 5.6 µH with ±10% tolerance
• Current Rating: Minimum 25 mA
• Package / Case: 1206 (3216 Metric) surface mount only
• Shielding: Shielded construction required
• Core Material: Ferrite core
• Operating Temperature Range: -55°C to 125°C minimum
• RoHS Compliance: ROHS3 Compliant

The AIML-1206-5R6K-T from Abracon LLC meets all substitution criteria. While the DC resistance specification differs (750mOhm Max versus 600mOhm Max), this represents a relaxation of the original specification within acceptable engineering tolerances for this component category and does not preclude functional equivalence in most applications.

Parameter Comparison

Engineering Selection Recommendations

The AIML-1206-5R6K-T is a direct functional equivalent for the obsolete CS321613-5R6K. Both components share identical inductance values, current ratings, package specifications, and operating temperature ranges. The substitute part is manufactured by Abracon LLC, an active supplier with current production status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), meeting regulatory and environmental requirements. The AIML-1206-5R6K-T is available in Tape & Reel packaging, suitable for automated assembly processes.

The primary specification difference is the DC resistance maximum: the substitute allows 750mOhm versus the original 600mOhm. This difference must be evaluated within the context of the specific circuit application to determine acceptability.

Frequently Asked Questions (FAQ)

Q: Can the AIML-1206-5R6K-T be used as a direct replacement for the CS321613-5R6K?

A: Yes, the AIML-1206-5R6K-T meets all critical substitution parameters: identical inductance (5.6 µH), current rating (25 mA), package (1206), shielding, core material, and operating temperature range. Circuit-level evaluation of the increased DC resistance specification is required for final design approval.

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

A: The substitute part specifies a maximum DC resistance of 750mOhm compared to the original 600mOhm. This represents a 25% relaxation of the specification. The impact on circuit performance depends on the application; designs with tight impedance or power dissipation requirements must account for this difference.

Q: Are both parts available in the same package format?

A: Both components use the 1206 (3216 Metric) surface mount package with identical footprints (0.126" L x 0.063" W / 3.20mm x 1.60mm). The AIML-1206-5R6K-T is supplied in Tape & Reel format, standard for automated assembly.

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

A: The CS321613-5R6K is obsolete, meaning Bourns Inc. no longer manufactures or supports this part. The AIML-1206-5R6K-T is active production, ensuring continued availability, technical support, and supply chain reliability.

Q: Do both parts meet the same compliance standards?

A: Yes, both components are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Both carry EAR99 ECCN classification and fall under HTSUS code 8504.50.8000.
