CS321613-R10K Equivalent & Substitute Parts

Part Overview

The CS321613-R10K is a 100 nH shielded multilayer inductor manufactured by Bourns Inc., rated for 250 mA with a maximum DC resistance of 200mOhm. This component is designed for surface mount applications in the 1206 (3216 Metric) package format. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing production and design requirements. Equivalent parts must maintain the same inductance value, current rating, package dimensions, and shielding characteristics to ensure functional compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS321613-R10K is determined by strict equivalence across the following critical parameters:

• Inductance Value: Must be 100 nH with ±10% tolerance
• Current Rating: Must support minimum 250 mA
• Package Format: Must be 1206 (3216 Metric) surface mount
• Shielding: Must be shielded to maintain electromagnetic isolation
• Core Material: Ferrite construction
• Operating Temperature Range: Must cover -55°C to 125°C
• DC Resistance: Must not exceed 200mOhm maximum

The AIML-1206-R10K-T from Abracon LLC meets all substitution criteria. While the DC resistance specification is slightly higher at 250mOhm maximum (compared to 200mOhm), this remains within acceptable tolerance for equivalent functionality in the same application class. The substitute maintains identical inductance, current rating, package dimensions, and thermal operating range.

Engineering Selection Recommendations

The AIML-1206-R10K-T is the qualified substitute for the obsolete CS321613-R10K. Selection is based on the following factors:

• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain continuity.
• Compliance: Both parts maintain ROHS3 compliance, meeting environmental and regulatory requirements.
• Electrical Equivalence: Identical inductance, tolerance, current rating, and operating temperature range ensure direct functional replacement.
• Package Compatibility: Identical 1206 (3216 Metric) surface mount package allows direct PCB layout compatibility without redesign.
• Shielding Characteristics: Both components feature shielded construction, maintaining electromagnetic performance in the original application.

The AIML-1206-R10K-T is available in active production with significantly higher inventory levels (32,809 pcs) compared to the obsolete part, supporting both immediate requirements and future production needs.

Frequently Asked Questions (FAQ)

Q: Can the AIML-1206-R10K-T be used as a direct replacement for the CS321613-R10K?

A: Yes. Both parts share identical inductance (100 nH), tolerance (±10%), current rating (250 mA), package format (1206), shielding type, and operating temperature range (-55°C to 125°C). The substitute is electrically and mechanically compatible for direct PCB substitution.

Q: What is the difference in DC resistance between these parts?

A: The CS321613-R10K specifies 200mOhm maximum DC resistance, while the AIML-1206-R10K-T specifies 250mOhm maximum. This 50mOhm difference remains within acceptable tolerance for equivalent component classification and does not affect functional performance in standard inductor applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the CS321613-R10K and AIML-1206-R10K-T are ROHS3 compliant, meeting environmental and regulatory standards for electronic component manufacturing.

Q: What is the physical size difference between these inductors?

A: Both parts use the 1206 (3216 Metric) package with identical length (0.126" / 3.20mm) and width (0.063" / 1.60mm). The seated height differs slightly: CS321613-R10K is 0.059" (1.50mm) maximum, while AIML-1206-R10K-T is 0.055" (1.40mm) maximum. This minor height variation does not affect PCB layout compatibility.

Q: Is the AIML-1206-R10K-T available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume production. The original part was supplied in standard packaging. Both formats are compatible with automated assembly equipment.

Q: Why is the original part listed as obsolete?

A: The CS321613-R10K is no longer in active production by Bourns Inc. The AIML-1206-R10K-T from Abracon LLC provides equivalent functionality and is actively manufactured, making it the appropriate substitute for new designs and production continuity.
