ISC1210ER470K Equivalent & Substitute Parts

Part Overview

The ISC1210ER470K is a 47 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 100 mA current rating with a maximum DC resistance of 8Ohm and is actively produced. Substitute parts are identified when equivalent inductance values, package dimensions, and electrical performance parameters align within acceptable tolerances for the intended application.

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210ER470K is determined by the following criteria:

• Inductance value must be 47 µH with ±10% tolerance
• Package must be 1210 (3225 Metric) for mechanical and thermal compatibility
• Mounting type must be Surface Mount
• Shielding configuration must be Shielded
• Operating temperature range must encompass -55°C ~ 125°C
• RoHS3 compliance required
• Current rating and DC resistance must be suitable for the application circuit requirements

The CMH322522-470KL from Bourns Inc. meets these core substitution criteria with equivalent inductance, package, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ISC1210ER470K and CMH322522-470KL are active products with ROHS3 compliance and REACH unaffected status. The primary distinction is the current rating: the ISC1210ER470K supports 100 mA while the CMH322522-470KL is rated for 60 mA. Selection between these parts depends on circuit current requirements. If the application draws current exceeding 60 mA, the ISC1210ER470K is the appropriate choice. For applications operating at or below 60 mA, the CMH322522-470KL provides equivalent electrical performance with lower DC resistance (7Ohm vs 8Ohm). Both components share identical inductance, tolerance, Q factor, self-resonant frequency, operating temperature range, and package dimensions within manufacturing tolerances.

Frequently Asked Questions (FAQ)

Q: Can the CMH322522-470KL replace the ISC1210ER470K in all applications?

A: Substitution is valid only if the circuit current requirement does not exceed 60 mA. The CMH322522-470KL has a lower current rating (60 mA vs 100 mA). Exceeding the rated current will cause saturation and performance degradation.

Q: Are the physical dimensions identical between these parts?

A: Dimensions are equivalent within manufacturing tolerances. Both use the 1210 (3225 Metric) package with length 0.126" (3.20mm) and width 0.098" (3.20mm x 2.49-2.50mm). Height differences are negligible (2.41mm vs 2.40mm), presenting no PCB layout concerns.

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

A: The ISC1210ER470K uses iron powder core material while the CMH322522-470KL uses ferrite. Both achieve the same inductance value and Q factor at 2.52MHz. Material selection affects frequency response characteristics and core loss profiles, but both are suitable for the specified operating parameters.

Q: Do both parts meet environmental and compliance requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and rated for -55°C ~ 125°C operating temperature with MSL 1 (unlimited moisture sensitivity level).

Q: Which part should be selected for new designs?

A: Selection is based on current requirements. For circuits requiring 100 mA capability, use ISC1210ER470K. For circuits operating at 60 mA or below, either part is acceptable; CMH322522-470KL offers slightly lower DC resistance.
