ISC1210ER6R8K Equivalent & Substitute Parts

Part Overview

The ISC1210ER6R8K is a 6.8 µH shielded drum core wirewound inductor manufactured by Vishay Dale, designed for surface mount applications in the 1210 (3225 Metric) package. This component operates across a temperature range of -55°C to 125°C with a maximum DC resistance of 1.6Ohm and supports a current rating of 205 mA. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute components become necessary when primary inventory is unavailable, when alternative core materials better suit specific circuit performance requirements, or when sourcing from multiple manufacturers is required for supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210ER6R8K is determined by the following critical parameters: inductance value (6.8 µH), inductance tolerance (±10%), package form factor (1210/3225 Metric), shielding requirement (shielded), surface mount capability, and operating temperature range (-55°C to 125°C). The substitute part CMH322522-6R8KL meets all these core requirements. Secondary parameters including current rating, DC resistance, and core material type (iron powder versus ferrite) may vary within acceptable limits for equivalent functionality. The substitute maintains identical inductance specification, tolerance, package dimensions, shielding, and temperature rating, ensuring direct functional compatibility in most applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ISC1210ER6R8K and CMH322522-6R8KL are active production components with ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compliance across both options. The primary distinction lies in current rating and DC resistance specifications. The ISC1210ER6R8K supports 205 mA with 1.6Ohm maximum DC resistance, while the CMH322522-6R8KL is rated for 180 mA with 1.8Ohm maximum DC resistance. Selection between these parts depends on circuit current requirements: applications requiring the full 205 mA rating or lower DC resistance dissipation must use the ISC1210ER6R8K. Applications operating at or below 180 mA with acceptable DC resistance of 1.8Ohm can utilize the CMH322522-6R8KL. Both components share identical inductance, tolerance, package footprint, shielding, and operating temperature specifications, confirming mechanical and electrical compatibility at the core functional level.

Frequently Asked Questions (FAQ)

Q: Can CMH322522-6R8KL directly replace ISC1210ER6R8K in all applications?

A: Direct replacement is possible only when circuit current does not exceed 180 mA and the additional 0.2Ohm DC resistance (1.8Ohm versus 1.6Ohm) does not negatively impact circuit performance. Both parts maintain identical inductance, tolerance, package dimensions, and operating temperature range.

Q: What is the significance of core material difference (iron powder versus ferrite)?

A: Core material affects frequency response characteristics and saturation behavior. The ISC1210ER6R8K uses iron powder core while CMH322522-6R8KL uses ferrite core. Both achieve identical Q factor (30 @ 7.96MHz) and inductance specification. Self-resonant frequency differs slightly (40MHz versus 35MHz), which may be relevant in high-frequency applications.

Q: Are package dimensions identical between these parts?

A: Package dimensions are functionally equivalent. Both use 1210 (3225 Metric) form factor with length 0.126" (3.20mm) and width 0.098" (2.49-2.50mm). Height difference is negligible (0.095" versus 0.094"), confirming PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ISC1210ER6R8K and CMH322522-6R8KL are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating, ensuring equivalent regulatory and environmental compliance.

Q: What determines whether a substitute is acceptable for a specific design?

A: Substitution acceptability is determined by: (1) matching inductance value and tolerance, (2) current rating meeting or exceeding circuit requirements, (3) DC resistance acceptable for power dissipation budget, (4) package compatibility with PCB layout, and (5) operating temperature range covering application environment. The CMH322522-6R8KL meets all criteria except current rating, which is 25 mA lower than the primary part.
