Key Parameters

Substitute Part Grouping Explanation

Substitute components for the CS321613-R82K must satisfy the following critical parameters to ensure functional equivalence:

• Inductance value of 820 nH with ±10% tolerance
• Current rating of 150 mA minimum
• Shielded multilayer construction with ferrite core
• 1206 (3216 Metric) surface mount package
• Operating temperature range of -55°C to 125°C
• RoHS3 compliance

The AIML-1206-R82K-T from Abracon LLC meets these core substitution criteria. While this substitute exhibits a higher maximum DC resistance (750mOhm versus 400mOhm), it maintains electrical compatibility within the specified inductance and current parameters. The substitute is currently in active production status, providing supply continuity for the obsolete Bourns component.

Parameter Comparison

Engineering Selection Recommendations

The AIML-1206-R82K-T from Abracon LLC is the qualified substitute for the obsolete CS321613-R82K. Both components are RoHS3 compliant and carry MSL Level 1 ratings, ensuring compatibility with standard manufacturing and storage protocols.

The primary design consideration is the increased DC resistance of the substitute (750mOhm maximum versus 400mOhm maximum). This parameter difference must be evaluated within the context of the specific circuit application. The substitute maintains identical inductance value, current rating, and operating temperature range, supporting direct replacement in most applications.

The substitute component is in active production status, providing assured supply availability and long-term support compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the AIML-1206-R82K-T directly replace the CS321613-R82K in all applications?

A: The AIML-1206-R82K-T meets the core electrical specifications (inductance, current rating, temperature range) and physical package requirements. The increased DC resistance (750mOhm versus 400mOhm) must be evaluated for the specific circuit design to ensure acceptable power dissipation and performance margins.

Q: Are there packaging differences between these components?

A: Both components use the 1206 (3216 Metric) surface mount package. The substitute has a slightly lower seated height (0.055" versus 0.059"), which is compatible with standard PCB assembly processes.

Q: What is the significance of the Q factor difference?

A: The original part exhibits a Q factor of 50 @ 25MHz, while the substitute shows 35 @ 25MHz. This reflects the higher DC resistance of the substitute and should be considered in high-frequency filtering or resonant circuit applications.

Q: Are both components RoHS compliant?

A: Yes, both the CS321613-R82K and AIML-1206-R82K-T are RoHS3 compliant and carry MSL Level 1 ratings.

Q: What is the self-resonant frequency difference?

A: The original part has a self-resonant frequency of 100MHz, while the substitute is rated at 110MHz. Both values support operation within standard RF and high-frequency applications for this inductance value.
