ISC1210ER101K Equivalent & Substitute Parts

Part Overview

The ISC1210ER101K is a 100 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 and is ROHS3 compliant. The part is currently active in production with 2100 units available in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to supply constraints, design optimization, or application-specific performance needs.

Key Parameters

Substitute Part Grouping Explanation

The CMH322522-101KL from Bourns Inc. is identified as a substitute based on the following alignment criteria:

Matching Parameters:

• Inductance: 100 µH (identical)
• Inductance Tolerance: ±10% (identical)
• Package / Case: 1210 (3225 Metric) (identical)
• Mounting Type: Surface Mount (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Shielding: Shielded (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Inductance Frequency - Test: 796 kHz (identical)

Differing Parameters:

• Current Rating: 40 mA (substitute) vs. 80 mA (main part)
• DC Resistance: 10 Ohm Max (substitute) vs. 12 Ohm Max (main part)
• Core Material: Ferrite (substitute) vs. Iron Powder (main part)
• Q @ Freq: 20 @ 796kHz (substitute) vs. 30 @ 796kHz (main part)
• Frequency - Self Resonant: 9 MHz (substitute) vs. 6 MHz (main part)

Substitution is valid when the application current requirement does not exceed 40 mA and lower DC resistance is acceptable or beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the ISC1210ER101K and CMH322522-101KL maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts is determined by application current requirements and DC resistance specifications. The ISC1210ER101K supports higher current operation at 80 mA with higher DC resistance. The CMH322522-101KL operates at 40 mA maximum with lower DC resistance of 10 Ohm Max. Identical package dimensions, temperature ratings, and inductance values ensure mechanical and thermal compatibility. Both components are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can CMH322522-101KL replace ISC1210ER101K in all applications?

A: Substitution is valid only when the circuit current requirement does not exceed 40 mA. If the application requires current operation above 40 mA, the ISC1210ER101K is required.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with matching length (0.126"), width (0.098"), and seated height specifications within 0.001" tolerance.

Q: What is the impact of different core materials?

A: The ISC1210ER101K uses iron powder core material while CMH322522-101KL uses ferrite core material. This results in different Q factors (30 vs. 20 @ 796kHz) and self-resonant frequencies (6 MHz vs. 9 MHz). Core material selection affects frequency response characteristics but does not impact DC inductance value or temperature operating range.

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

A: Yes. Both components operate across -55°C to 125°C with identical temperature ratings.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.8000.
