CIG22B2R2MNE Equivalent & Substitute Parts

Part Overview

The CIG22B2R2MNE is a 2.2 µH shielded multilayer inductor manufactured by Samsung Electro-Mechanics, designed for surface mount applications in the 1008 (2520 Metric) package. This component operates at 1.1 A rated current with 183 mOhm DC resistance and supports operating temperatures from -40°C to 125°C. The part is classified as obsolete, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. Substitute components must maintain electrical performance within the specified inductance, current rating, and DC resistance parameters while meeting RoHS3 compliance and MSL Level 1 requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the CIG22B2R2MNE are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 2.2 µH (±20% tolerance)
• Current rating: minimum 1.1 A
• Package / Case: 1008 (2520 Metric)
• Mounting type: Surface Mount
• Shielding: Shielded configuration
• RoHS3 compliance and MSL Level 1 rating

Secondary Compatibility Factors:

• DC resistance within acceptable operating limits
• Operating temperature range compatibility
• Physical dimensions matching 1008 package specification

The substitute parts identified maintain the core electrical specifications required for direct replacement while accommodating minor variations in DC resistance and temperature operating ranges. All candidates are surface mount components in identical package dimensions with equivalent shielding characteristics.

Engineering Selection Recommendations

LQM2HPN2R2MGSL (Murata Electronics) — Recommended for Active Production

The LQM2HPN2R2MGSL is the primary substitute for new designs and ongoing production. This component maintains identical inductance (2.2 µH), current rating (1.1 A), and package specifications. The part carries Active product status, ensuring long-term availability and supply chain stability. DC resistance of 225 mOhm Max remains within acceptable operating parameters. ROHS3 compliance and MSL Level 1 rating match the original specification. The operating temperature range of -40°C to 85°C covers standard industrial applications, though designs requiring the full -40°C to 125°C range of the original part require thermal analysis.

VLS252010ET-2R2M and VLS252010ET-2R2M-CA (TDK Corporation) — Alternative Substitutes

Both TDK variants provide functional equivalence with enhanced current rating (1.2 A) and improved DC resistance (190 mOhm Max). These components are classified as Not For New Designs, indicating limited future availability. The VLS252010ET-2R2M is supplied in Cut Tape (CT) & Digi-Reel® packaging, while VLS252010ET-2R2M-CA uses Tape & Reel (TR) packaging. Operating temperature range extends to 105°C, providing intermediate thermal coverage. These parts are suitable for legacy system maintenance and repair applications where supply from active manufacturers is unavailable.

Frequently Asked Questions (FAQ)

Q: Can the LQM2HPN2R2MGSL directly replace the CIG22B2R2MNE in existing designs?

A: Yes, the LQM2HPN2R2MGSL provides direct electrical and mechanical compatibility. Both components share identical inductance (2.2 µH), current rating (1.1 A), package dimensions (1008 / 2520 Metric), and shielding configuration. DC resistance variation (225 mOhm Max vs. 183 mOhm) falls within acceptable operating tolerances for most applications. Verify thermal requirements if operation above 85°C is specified.

Q: What is the difference between the two TDK variants?

A: VLS252010ET-2R2M and VLS252010ET-2R2M-CA are electrically identical with matching inductance, current rating, and DC resistance specifications. The primary difference is packaging format: VLS252010ET-2R2M uses Cut Tape (CT) & Digi-Reel® supply, while VLS252010ET-2R2M-CA uses Tape & Reel (TR). Both are classified as Not For New Designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all identified substitute components—LQM2HPN2R2MGSL, VLS252010ET-2R2M, and VLS252010ET-2R2M-CA—carry ROHS3 Compliant certification matching the original CIG22B2R2MNE specification.

Q: What is the significance of MSL Level 1 rating?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. All substitute parts maintain this rating, eliminating special storage or handling procedures.

Q: Can I use the TDK parts if my application requires operation at 125°C?

A: The TDK variants (VLS252010ET-2R2M and VLS252010ET-2R2M-CA) are rated to 105°C maximum. For applications requiring 125°C operation, the LQM2HPN2R2MGSL is limited to 85°C. The original CIG22B2R2MNE specification of -40°C to 125°C cannot be fully matched by available substitutes. Thermal analysis and derating calculations are required for high-temperature applications.

Q: What is the difference between multilayer and drum core inductor construction?

A: The CIG22B2R2MNE uses multilayer construction, while the TDK substitutes (VLS252010ET-2R2M and VLS252010ET-2R2M-CA) employ drum core, wirewound construction with ferrite core material. Both construction types provide shielding and meet the specified electrical parameters. Multilayer construction typically offers better high-frequency performance, while wirewound construction provides robust mechanical characteristics.

Q: Is the higher current rating (1.2 A) of TDK parts a concern?

A: No. The 1.2 A current rating of TDK variants exceeds the 1.1 A requirement, providing additional design margin. This represents an improvement over the original specification and does not create compatibility issues.
