Substitute Part Grouping Explanation

Substitution for the ISC1210ER180K is determined by the following critical parameters:

• Inductance value: 18 µH (matching value required)
• Package / Case: 1210 (3225 Metric) (physical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Shielding: Shielded (electromagnetic performance)
• Operating Temperature Range: -55°C ~ 125°C (thermal compatibility)
• Tolerance: ±10% (performance specification)

The substitute part CMH322522-180KL meets these core substitution criteria. Variations in current rating, DC resistance, core material, and self-resonant frequency are acceptable within the scope of equivalent functionality when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the ISC1210ER180K and CMH322522-180KL are active production components with ROHS3 compliance and identical moisture sensitivity ratings. Selection between these parts depends on application-specific current requirements and DC resistance constraints. The ISC1210ER180K supports higher current capacity at 155 mA with lower DC resistance of 2.7Ohm maximum. The CMH322522-180KL operates at 120 mA maximum current with 3.3Ohm maximum DC resistance. Both components maintain identical inductance values, tolerance specifications, and operating temperature ranges. The choice between iron powder and ferrite core materials reflects manufacturer design differences and may influence frequency response characteristics in specific circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CMH322522-180KL replace ISC1210ER180K in all applications?

A: Substitution is valid when the application current requirement does not exceed 120 mA and the higher DC resistance of 3.3Ohm maximum is acceptable. If the circuit requires the full 155 mA current capacity or lower DC resistance of the original part, substitution is not appropriate.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 1210 (3225 Metric) package with matching length and width dimensions of 0.126" L x 0.098" W (3.20mm x 2.49mm for ISC1210ER180K and 3.20mm x 2.50mm for CMH322522-180KL). Height differences are negligible at 0.095" (2.41mm) versus 0.094" (2.40mm), presenting no assembly compatibility issues.

Q: What is the significance of core material differences?

A: The ISC1210ER180K uses iron powder core material while CMH322522-180KL uses ferrite core material. Both are shielded designs with identical Q factors at 2.52MHz. The ferrite core in the substitute part exhibits a higher self-resonant frequency of 20MHz compared to 17MHz in the original part, which may affect performance in high-frequency applications.

Q: Are both parts suitable for the same temperature range?

A: Yes, both components operate across -55°C to 125°C, providing identical thermal performance specifications.

Q: What compliance certifications apply to both parts?

A: Both the ISC1210ER180K and CMH322522-180KL are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.8000.
