CIG22B2R2MLE Equivalent & Substitute Parts

Part Overview

The CIG22B2R2MLE is a 2.2 µH shielded multilayer inductor manufactured by Samsung Electro-Mechanics, rated for 900 mA continuous current with 170mOhm DC resistance. This component is packaged in the 1008 (2520 Metric) surface mount form factor and operates across the temperature range of -40°C to 125°C. The part is classified as obsolete, necessitating identification of active equivalent components that maintain functional compatibility within specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

LQM2HPN2R2MJ0L (Murata Electronics) - Primary Substitute

This component is the preferred substitute for the CIG22B2R2MLE. It exceeds the original current rating specification (1 A versus 900 mA) and provides superior DC resistance performance (150 mOhm Max versus 170 mOhm). The extended operating temperature range (-55°C to 125°C) encompasses the original specification. Product status is active, ensuring long-term availability. Packaging and mechanical dimensions are identical to the original part. Height increase from 0.80mm to 1.00mm must be verified against PCB layout constraints.

LQM2HPN2R2MGSL (Murata Electronics) - Secondary Substitute

This component provides the highest current rating (1.1 A) among available substitutes. However, DC resistance is elevated to 225 mOhm Max, representing a 32% increase over the original specification. Operating temperature range is restricted to -40°C to 85°C, which does not extend to the original upper limit of 125°C. This substitute is suitable only for applications where the reduced temperature range and elevated DC resistance are acceptable. Product status is active.

Both substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and identical inductance specifications. Selection between LQM2HPN2R2MJ0L and LQM2HPN2R2MGSL depends on application-specific requirements for current capacity, thermal performance, and operating temperature envelope.

Frequently Asked Questions (FAQ)

Q: Why is the CIG22B2R2MLE classified as obsolete?

A: The CIG22B2R2MLE is no longer in active production by Samsung Electro-Mechanics. Substitute components from active manufacturers must be identified for new designs or component replenishment.

Q: Can LQM2HPN2R2MJ0L be used as a direct replacement for CIG22B2R2MLE?

A: Yes, LQM2HPN2R2MJ0L meets all mandatory electrical and mechanical parameters. The primary consideration is the increased seated height (1.00mm versus 0.80mm), which must be verified against PCB layout and clearance requirements.

Q: What is the significance of the DC resistance difference between substitutes?

A: DC resistance directly affects power dissipation and thermal performance. LQM2HPN2R2MJ0L (150 mOhm Max) provides lower dissipation than the original (170 mOhm), while LQM2HPN2R2MGSL (225 mOhm Max) increases dissipation. Selection depends on thermal budget and current profile of the application.

Q: Are both Murata substitutes RoHS3 compliant?

A: Yes, both LQM2HPN2R2MJ0L and LQM2HPN2R2MGSL are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original part specifications.

Q: What is the impact of the operating temperature range difference?

A: LQM2HPN2R2MJ0L extends the lower temperature limit to -55°C, providing broader environmental coverage. LQM2HPN2R2MGSL restricts the upper limit to 85°C, which does not meet the original 125°C specification and may be unsuitable for high-temperature applications.

Q: How do the current ratings affect component selection?

A: Both substitutes exceed the original 900 mA rating. LQM2HPN2R2MJ0L provides 1 A, while LQM2HPN2R2MGSL provides 1.1 A. Higher current ratings provide design margin but do not affect compatibility for applications requiring 900 mA or less.

Q: Is the package footprint identical between all three parts?

A: Yes, all three components use the 1008 (2520 Metric) package with identical planar dimensions (0.098" L x 0.079" W). Seated height varies: original 0.80mm, substitutes 1.00mm. PCB layout verification is required.

Q: What certifications are maintained across all parts?

A: All parts maintain ROHS3 compliance, MSL rating 1 (Unlimited), REACH Unaffected status, and ECCN EAR99 classification.
