ISC1210ER220K Equivalent & Substitute Parts

Part Overview

The ISC1210ER220K is a 22 µH shielded drum core wirewound inductor manufactured by Vishay Dale, designed for surface mount applications in the 1210 (3225 Metric) package. This component operates at 150 mA maximum current with a DC resistance of 3.1 Ohm maximum and is rated for operating temperatures from -55°C to 125°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent inductance values, package dimensions, and electrical performance parameters align within acceptable tolerances for the intended application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210ER220K is determined by the following critical parameters:

• Inductance value of 22 µH with ±10% tolerance
• Package / Case designation of 1210 (3225 Metric) for mechanical and PCB compatibility
• Shielded construction to maintain electromagnetic isolation
• Operating temperature range of -55°C to 125°C
• Surface mount mounting type
• ROHS3 compliance for regulatory alignment

The substitute part CMH322522-220KL meets these core substitution criteria. Variations in current rating, DC resistance, and core material (ferrite versus iron powder) are within acceptable engineering parameters for equivalent functionality, provided the application current requirement does not exceed the substitute part's 110 mA rating.

Parameter Comparison

Engineering Selection Recommendations

Both the ISC1210ER220K and CMH322522-220KL are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application current requirements. The ISC1210ER220K supports 150 mA operation, while the CMH322522-220KL is rated for 110 mA maximum. Applications requiring current levels above 110 mA must use the ISC1210ER220K. For applications operating at or below 110 mA, the CMH322522-220KL provides equivalent inductance and frequency characteristics with ferrite core construction. Both parts maintain identical operating temperature ranges and package dimensions suitable for 1210 (3225 Metric) PCB footprints.

Frequently Asked Questions (FAQ)

Q: Can CMH322522-220KL replace ISC1210ER220K in all applications?

A: Substitution is valid only when circuit current requirements do not exceed 110 mA. The CMH322522-220KL has a lower current rating (110 mA versus 150 mA) and higher DC resistance (3.7 Ohm Max versus 3.1 Ohm Max). Verify application current specifications before substitution.

Q: Are the physical dimensions identical between these parts?

A: Dimensions are nearly identical. Both use the 1210 (3225 Metric) package with length 0.126" (3.20mm) and width 0.098" (2.49-2.50mm). Height seated maximum differs by 0.001" (0.01mm), which is negligible for PCB assembly compatibility.

Q: What is the difference between iron powder and ferrite core materials?

A: The ISC1210ER220K uses iron powder core material, while the CMH322522-220KL uses ferrite. Both achieve the same 22 µH inductance and 30 Q factor at 2.52 MHz. Core material selection affects frequency response characteristics; the ferrite core exhibits a higher self-resonant frequency (19 MHz versus 16 MHz).

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the ISC1210ER220K and CMH322522-220KL are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level), suitable for standard storage and handling conditions.

Q: What is the inductance tolerance for these parts?

A: Both parts carry ±10% inductance tolerance, meaning the actual inductance value will fall within the range of 19.8 µH to 24.2 µH at the test frequency of 2.52 MHz.
