Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IMC1812ES2R2K are qualified based on the following criteria:

• Inductance Value: 2.2 µH ±10% tolerance
• Current Rating: 380 mA minimum
• DC Resistance: 700mOhm maximum
• Package: 1812 (4532 Metric) surface mount
• Frequency Characteristics: Q @ 7.96MHz = 50
• Environmental Compliance: ROHS3 compliant, MSL 1

All substitute parts listed maintain these core electrical and mechanical parameters, ensuring functional equivalence in circuit applications. Variations in core material (iron powder versus ferrite), operating temperature ranges, and self-resonant frequency do not affect substitutability for applications within the specified electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—IMC1812ES2R2K, 3613C2R2K, 74476602, and CM453232-2R2KL—are active production components with ROHS3 compliance and MSL 1 rating. Selection among these equivalents may be based on:

• Availability: Current inventory levels range from 951 to 2093 pieces across suppliers
• Operating Temperature Range: IMC1812ES2R2K and CM453232-2R2KL support -55°C to 125°C; 3613C2R2K supports -30°C to 100°C; 74476602 supports -40°C to 105°C
• Core Material: IMC1812ES2R2K uses iron powder core; 3613C2R2K, 74476602, and CM453232-2R2KL use ferrite core
• Self-Resonant Frequency: IMC1812ES2R2K, 3613C2R2K, and CM453232-2R2KL specify 55MHz; 74476602 specifies 185MHz

All parts meet the electrical and mechanical requirements for direct substitution in applications designed for the IMC1812ES2R2K.

Frequently Asked Questions (FAQ)

Q: Can I substitute the IMC1812ES2R2K with any of the listed parts? A: Yes. All listed parts meet the core electrical specifications: 2.2 µH inductance, 380 mA current rating, 700mOhm maximum DC resistance, and 1812 (4532 Metric) package. They are mechanically and electrically interchangeable.

Q: What is the difference between iron powder and ferrite core materials? A: Both core materials are used in the listed substitutes. The choice between them does not affect substitutability for applications within the specified electrical envelope. Core material selection is typically driven by application-specific frequency response and loss characteristics.

Q: Does the operating temperature range affect substitutability? A: Operating temperature range does not affect substitutability if your application operates within the overlapping temperature range of all parts (-30°C to 100°C). For applications requiring extended temperature operation, verify the specific part's temperature rating.

Q: Are all parts ROHS3 compliant? A: Yes. All four parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Q: What is the significance of the 1812 (4532 Metric) package designation? A: The 1812 package is a surface mount inductor package with dimensions 0.177" L × 0.126" W (4.50mm × 3.20mm). All listed parts use this identical package, ensuring PCB footprint compatibility.

Q: Can I use these parts interchangeably on the same PCB? A: Yes. All parts share identical package dimensions and mounting type (surface mount), allowing direct PCB footprint compatibility and assembly process equivalence.
