IMC1210EB2R2K Equivalent & Substitute Parts

Part Overview

The IMC1210EB2R2K is a 2.2 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 320 mA maximum current with 1Ohm maximum DC resistance. This surface mount component operates across the temperature range of -55°C to 125°C and is ROHS3 compliant. The part is currently active in production with 689 pieces available in stock.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation within alternative electrical and mechanical specifications. The CM322522-2R2KL from Bourns Inc. serves as a qualified substitute based on matching inductance value, tolerance, frequency characteristics, and core geometry.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1210EB2R2K is determined by the following critical parameters:

Inductance Value & Tolerance: The substitute must maintain 2.2 µH inductance with ±10% tolerance to ensure circuit performance within design specifications.

Frequency Characteristics: The Q factor at 7.96MHz and self-resonant frequency must remain within acceptable operating ranges for the intended application frequency band.

Physical Footprint: Surface mount package compatibility requires matching or compatible case dimensions (1210/3225 Metric) to ensure PCB layout compatibility.

Core Material & Shielding: Both parts utilize unshielded drum core construction, maintaining electromagnetic field characteristics.

Temperature Range: Operating temperature specifications must support the application environment.

Compliance & Certifications: ROHS3 compliance and MSL rating ensure regulatory and manufacturing process compatibility.

The CM322522-2R2KL qualifies as a substitute based on matching inductance, tolerance, frequency characteristics, and physical dimensions. However, the substitute exhibits reduced current rating (190 mA versus 320 mA) and lower maximum DC resistance (950mOhm versus 1Ohm), which may limit application scope to lower-current circuits.

Parameter Comparison

Engineering Selection Recommendations

Both the IMC1210EB2R2K and CM322522-2R2KL maintain ROHS3 compliance and MSL Level 1 ratings, ensuring compatibility with standard manufacturing processes and regulatory requirements.

The primary selection criterion depends on circuit current requirements. The IMC1210EB2R2K supports applications requiring up to 320 mA continuous current, while the CM322522-2R2KL is suitable for circuits operating at 190 mA or below. The lower DC resistance of the CM322522-2R2KL (950mOhm) results in reduced power dissipation compared to the IMC1210EB2R2K (1Ohm Max) at equivalent current levels.

The operating temperature range of the IMC1210EB2R2K extends to -55°C, providing broader environmental coverage than the CM322522-2R2KL (-40°C minimum). Applications requiring sub-zero operation below -40°C necessitate the primary part.

Physical dimensions are nearly identical, with the CM322522-2R2KL offering a lower seated height (2.20mm versus 2.41mm), which may provide advantages in space-constrained PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the CM322522-2R2KL replace the IMC1210EB2R2K in all applications?

A: Substitution is valid only when circuit current requirements do not exceed 190 mA. Applications designed for the full 320 mA rating of the IMC1210EB2R2K require the primary part or an equivalent with matching current specifications.

Q: Are the physical dimensions compatible for PCB layout?

A: Yes. Both parts use the 1210 (3225 Metric) surface mount package with matching length and width (3.20mm x 2.49-2.50mm). The CM322522-2R2KL has a lower seated height (2.20mm versus 2.41mm), which is compatible with standard PCB assembly processes.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the IMC1210EB2R2K and CM322522-2R2KL are ROHS3 compliant with MSL Level 1 ratings, ensuring compatibility with current manufacturing and environmental standards.

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

A: The IMC1210EB2R2K uses iron powder core material, while the CM322522-2R2KL uses ferrite core material. Both achieve the same inductance value and Q factor at 7.96MHz, with the ferrite-core substitute exhibiting a slightly higher self-resonant frequency (80MHz versus 75MHz).

Q: How do the DC resistance values affect circuit performance?

A: The CM322522-2R2KL exhibits lower DC resistance (950mOhm Max versus 1Ohm Max), resulting in reduced resistive losses and lower power dissipation at equivalent current levels. This characteristic may improve efficiency in current-limited applications.

Q: Is the operating temperature range a limiting factor for substitution?

A: The IMC1210EB2R2K supports operation down to -55°C, while the CM322522-2R2KL minimum is -40°C. Applications requiring operation below -40°C must use the primary part or an equivalent with extended low-temperature specifications.
