IMC1812EB2R2K Equivalent & Substitute Parts

Part Overview

The IMC1812EB2R2K is a 2.2 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 380 mA with a maximum DC resistance of 700mOhm. This surface mount component in 1812 (4532 Metric) package is designed for applications requiring fixed inductance in compact form factors. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified based on matching electrical specifications and mechanical compatibility within the same package class.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1812EB2R2K is determined by strict equivalence across the following critical parameters: inductance value (2.2 µH), tolerance (±10%), current rating (380 mA), DC resistance (700mOhm maximum), package designation (1812/4532 Metric), and surface mount compatibility. All identified substitutes maintain these core electrical and mechanical specifications. Variations in core material (iron powder versus ferrite), operating temperature range, and self-resonant frequency are noted but do not preclude functional substitution when application requirements fall within the overlapping specifications of both the primary and substitute parts.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status and full RoHS3 compliance with unlimited moisture sensitivity ratings, ensuring regulatory and environmental compatibility across applications. The IMC1812EB2R2K, 3613C2R2K, and CM453232-2R2KL share identical self-resonant frequency specifications (55MHz), while the 74476602 offers extended self-resonant frequency performance at 185MHz. Selection between substitutes should account for operating temperature requirements: the IMC1812EB2R2K and CM453232-2R2KL support the full -55°C to 125°C range, whereas the 3613C2R2K operates within -30°C to 100°C and the 74476602 within -40°C to 105°C. Core material differences (iron powder versus ferrite) may influence frequency response characteristics in specific circuit topologies but do not affect the fundamental electrical parameters that define substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Can the 3613C2R2K replace the IMC1812EB2R2K in all applications?

A: The 3613C2R2K is electrically equivalent across inductance, current rating, and DC resistance specifications. However, its operating temperature range (-30°C to 100°C) is narrower than the IMC1812EB2R2K (-55°C to 125°C). Substitution is valid only when the application operates within the 3613C2R2K's temperature limits.

Q: What is the significance of the different core materials?

A: The IMC1812EB2R2K uses iron powder core material, while the 3613C2R2K, 74476602, and CM453232-2R2KL use ferrite cores. Both materials achieve the specified electrical parameters. Core material selection affects frequency response and temperature stability characteristics but does not preclude functional substitution when electrical specifications match.

Q: Why does the 74476602 have a higher self-resonant frequency?

A: The 74476602 exhibits a self-resonant frequency of 185MHz compared to 55MHz for the other parts. This difference reflects design variations in the ferrite core and winding configuration but does not affect substitution eligibility when the application operates below the self-resonant frequency threshold.

Q: Are packaging and mounting considerations identical across all substitutes?

A: All four parts use the 1812 (4532 Metric) surface mount package with identical footprint dimensions (0.177" L x 0.126" W / 4.50mm x 3.20mm). Height variations exist: IMC1812EB2R2K, 3613C2R2K, and CM453232-2R2KL measure 0.134" (3.40mm), while the 74476602 measures 0.142" (3.60mm). Verify PCB clearance specifications for the 74476602 in space-constrained designs.

Q: What packaging formats are available for these substitutes?

A: The IMC1812EB2R2K is supplied in Bulk packaging. The 3613C2R2K, 74476602, and CM453232-2R2KL are supplied in Tape & Reel (TR) format. Confirm packaging requirements with procurement specifications before component selection.
