IMC1210EB2R7K Equivalent & Substitute Parts

Part Overview

The IMC1210EB2R7K is a 2.7 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 290 mA with a maximum DC resistance of 1.1Ohm. This surface mount component operates across the temperature range of -55°C to 125°C and is classified as Active product status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the same package footprint and performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1210EB2R7K is determined by strict alignment of the following critical parameters:

• Inductance value: 2.7 µH with ±10% tolerance
• Current rating: 290 mA minimum
• DC resistance: 1.1Ohm maximum
• Package footprint: 1210 (3225 Metric) surface mount
• Q factor: 30 @ 7.96MHz
• Shielding configuration: Unshielded
• RoHS3 compliance and MSL Level 1 rating

The substitute part 744764027 (Würth Elektronik WE-GF series) meets all electrical specifications and mechanical compatibility requirements. Differences in core material (ferrite vs. iron powder) and operating temperature range do not preclude substitution when the application environment remains within the substitute's specified limits.

Parameter Comparison

Engineering Selection Recommendations

Both the IMC1210EB2R7K and 744764027 maintain Active product status with full RoHS3 compliance and MSL Level 1 rating. Selection between these parts should be based on application-specific temperature requirements. The IMC1210EB2R7K supports the extended lower temperature limit of -55°C, while the 744764027 operates to -40°C minimum. For applications requiring operation below -40°C, the Vishay Dale part is required. For standard industrial and commercial temperature ranges, both parts are functionally equivalent. Packaging format differs (Bulk vs. Tape & Reel), which may influence procurement and assembly logistics.

Frequently Asked Questions (FAQ)

Q: Can 744764027 replace IMC1210EB2R7K in all applications?

A: Substitution is valid when the application environment remains within -40°C to 105°C. Applications requiring operation below -40°C must use the IMC1210EB2R7K.

Q: What is the impact of different core materials (iron powder vs. ferrite)?

A: Both materials achieve the specified inductance, current rating, DC resistance, and Q factor at 7.96MHz. Core material differences do not affect electrical performance within the stated parameters.

Q: Are the physical dimensions compatible for PCB layout?

A: Yes. Both parts use the 1210 (3225 Metric) package with dimensions of 0.126" L x 0.098" W and seated heights within 0.094" to 0.095". PCB footprints are interchangeable.

Q: Does packaging format (Bulk vs. Tape & Reel) affect electrical performance?

A: No. Packaging format is a logistics and assembly consideration only. Electrical and mechanical specifications remain identical.

Q: What is the self-resonant frequency difference significance?

A: The IMC1210EB2R7K has a self-resonant frequency of 70MHz, while 744764027 is rated at 80MHz. Both exceed typical application frequencies and do not impact substitution eligibility for standard inductor applications.
