Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISC1210ER2R2K are qualified based on the following critical parameters:

Inductance value must match at 2.2 µH with ±10% tolerance. Current rating must be equal to or greater than 320 mA to ensure safe operation under specified load conditions. Package and case dimensions must conform to 1210 (3225 Metric) surface mount specifications to guarantee mechanical compatibility with existing PCB layouts. Operating temperature range must encompass -55°C to 125°C minimum. Shielding type must be shielded to maintain electromagnetic compatibility. RoHS3 compliance and MSL rating of 1 are required for regulatory and manufacturing process compatibility.

The CMH322522-2R2KL from Bourns Inc. qualifies as a direct substitute based on matching inductance, current rating, package dimensions, operating temperature range, shielding configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ISC1210ER2R2K and CMH322522-2R2KL are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications. The CMH322522-2R2KL exhibits a slightly higher DC resistance of 1Ohm maximum compared to the ISC1210ER2R2K at 900mOhm maximum, and a higher self-resonant frequency of 75MHz versus 65MHz. Both components maintain identical inductance values, current ratings, operating temperature ranges, and package dimensions within acceptable mechanical tolerances. Selection between these parts should be based on specific circuit requirements regarding DC resistance losses and frequency response characteristics at the application's operating point.

Frequently Asked Questions (FAQ)

Q: Can the CMH322522-2R2KL be used as a direct replacement for the ISC1210ER2R2K?

A: Yes, the CMH322522-2R2KL qualifies as a direct substitute. Both components share identical inductance values (2.2 µH), current ratings (320 mA), package dimensions (1210 / 3225 Metric), operating temperature ranges (-55°C to 125°C), and compliance certifications (ROHS3, REACH unaffected). The primary difference is DC resistance specification, where the Bourns part has a maximum of 1Ohm compared to 900mOhm for the Vishay part.

Q: What are the mechanical compatibility considerations?

A: Both parts conform to the 1210 (3225 Metric) surface mount package with dimensions of 0.126" L x 0.098" W and seated heights within 0.094" to 0.095". These dimensions are within standard PCB layout tolerances and are mechanically interchangeable without requiring board redesign.

Q: How do the DC resistance specifications affect circuit performance?

A: The ISC1210ER2R2K specifies a maximum DC resistance of 900mOhm, while the CMH322522-2R2KL specifies 1Ohm maximum. In applications where inductor losses directly impact efficiency or thermal performance, the lower resistance of the Vishay part may be preferable. For most general-purpose filtering and energy storage applications, both specifications are functionally equivalent.

Q: Are there frequency response differences between these parts?

A: The self-resonant frequencies differ slightly, with the ISC1210ER2R2K rated at 65MHz and the CMH322522-2R2KL at 75MHz. Both maintain identical Q factors of 30 at 7.96MHz test frequency. For applications operating below 65MHz, both parts perform identically. Applications requiring operation closer to resonant frequencies should verify performance with the specific part's frequency response characteristics.

Q: What is the moisture sensitivity level, and why does it matter?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures, simplifying supply chain management and manufacturing processes.
