Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210ER1R2K is determined by the following critical parameters:

• Inductance value: 1.2 µH (within ±10% tolerance)
• Current rating: 390 mA minimum
• Package / Case: 1210 (3225 Metric) surface mount
• Shielding: Shielded configuration
• Operating temperature range: -55°C to 125°C
• RoHS3 compliance and REACH unaffected status

The CMH322522-1R2KL from Bourns Inc. meets all substitution criteria. Variations in DC resistance (650 mOhm vs. 750 mOhm) and core material (Iron Powder vs. Ferrite) remain within acceptable engineering tolerances for this product category, as both maintain the specified inductance, current rating, and thermal performance.

Parameter Comparison

Engineering Selection Recommendations

Both the ISC1210ER1R2K and CMH322522-1R2KL are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The ISC1210ER1R2K features a lower maximum DC resistance of 650 mOhm compared to the CMH322522-1R2KL at 750 mOhm. Selection between these parts should be based on circuit requirements for power dissipation and thermal performance. Both components maintain identical inductance values, current ratings, operating temperature ranges, and package dimensions suitable for direct PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can the CMH322522-1R2KL replace the ISC1210ER1R2K in all applications?

A: The CMH322522-1R2KL meets the core electrical and mechanical specifications for substitution. The primary difference is the DC resistance maximum of 750 mOhm versus 650 mOhm. Applications sensitive to power dissipation or thermal performance should evaluate this 100 mOhm difference against circuit requirements.

Q: Are the physical dimensions compatible for PCB layout?

A: Yes. Both components use the 1210 (3225 Metric) package with nearly identical footprints. The CMH322522-1R2KL has a maximum seated height of 0.094" (2.40mm) compared to 0.095" (2.41mm) for the ISC1210ER1R2K, representing a negligible difference for standard PCB assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ISC1210ER1R2K and CMH322522-1R2KL are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of the core material difference?

A: The ISC1210ER1R2K uses an iron powder core while the CMH322522-1R2KL uses a ferrite core. Both configurations achieve the specified 1.2 µH inductance and 390 mA current rating. Core material selection affects frequency response characteristics, with the ISC1210ER1R2K showing a self-resonant frequency of 110 MHz versus 100 MHz for the CMH322522-1R2KL.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both components have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
