Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1210-683K is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 68 µH (±10% tolerance)
• DC Resistance: 9Ohm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

• Current rating capability (minimum 65 mA for substitute parts)
• Q factor performance at test frequency (minimum 30)
• Operating temperature range coverage (-40°C minimum acceptable)
• Package footprint compatibility (1210 or equivalent metric dimensions)

The CM322522-680KL from Bourns Inc. qualifies as a substitute part based on matching inductance, DC resistance, core material, shielding type, and moisture sensitivity specifications. Variations in current rating, package designation, and self-resonant frequency are documented for engineering evaluation.

Engineering Selection Recommendations

1210-683K (API Delevan Inc.) - Primary Selection:

• Active product status with established supply (801 pieces in stock)
• Supports full operating temperature range (-55°C to 125°C)
• Current rating of 144 mA accommodates higher-current applications
• RoHS non-compliant status requires verification against end-product regulatory requirements

CM322522-680KL (Bourns Inc.) - Substitute Selection:

• Active product status with higher inventory availability (14,037 pieces in stock)
• ROHS3 compliance suitable for applications requiring RoHS certification
• Current rating of 65 mA limits use to lower-current circuit designs
• Operating temperature minimum of -40°C excludes applications requiring -55°C operation
• Lower profile (2.20mm vs. 2.57mm) provides design flexibility for space-constrained layouts
• Higher self-resonant frequency (15 MHz vs. 10 MHz) extends high-frequency performance envelope

Selection Criteria:

• If application current requirement exceeds 65 mA, use 1210-683K
• If application requires operation below -40°C, use 1210-683K
• If RoHS3 compliance is mandatory, use CM322522-680KL
• If PCB height constraints exist, CM322522-680KL offers lower profile advantage
• Both parts maintain identical inductance, tolerance, DC resistance, and moisture sensitivity specifications

Frequently Asked Questions (FAQ)

Q: Can CM322522-680KL replace 1210-683K in all applications?

A: No. The substitute part has a lower current rating (65 mA vs. 144 mA) and narrower operating temperature range (-40°C to 125°C vs. -55°C to 125°C). Verify that your application current does not exceed 65 mA and that minimum operating temperature is not below -40°C before substitution.

Q: What is the difference between the package designations "1210 (3225 Metric)" and "Nonstandard"?

A: The 1210-683K uses the standard 1210 package designation. The CM322522-680KL uses a nonstandard package designation but maintains similar physical dimensions (3.20mm x 2.50mm vs. 3.25mm x 2.42mm). Verify PCB footprint compatibility with your design before substitution.

Q: Are there compliance differences between these parts?

A: Yes. The 1210-683K is RoHS non-compliant, while CM322522-680KL is ROHS3 compliant. Both are REACH unaffected and classified as EAR99. Select based on your end-product regulatory requirements.

Q: How do the self-resonant frequencies affect circuit performance?

A: The 1210-683K has a self-resonant frequency of 10 MHz, while CM322522-680KL is rated at 15 MHz. The higher SRF of the substitute part extends usable frequency range for high-frequency applications. Both maintain Q factor of 30 at their respective test frequencies (2.5 MHz and 2.52 MHz).

Q: What is the significance of the height difference (2.57mm vs. 2.20mm)?

A: The CM322522-680KL has a lower seated height, which may provide design advantages in space-constrained PCB layouts. Verify that your design does not rely on the taller profile of the 1210-683K for mechanical clearance or component stacking.

Q: Can I use these parts interchangeably in my design?

A: Interchangeability depends on three factors: (1) application current requirement must not exceed 65 mA for the substitute, (2) minimum operating temperature must be -40°C or higher for the substitute, and (3) PCB footprint must accommodate the nonstandard package dimensions of the substitute. Confirm all three conditions before implementing substitution.
