Key Parameters

Substitute Part Grouping Explanation

Substitution of the CI100505-2N2D is determined by strict equivalence across the following critical parameters:

• Inductance Value: 2.2 nH with tolerance ±0.3nH
• Current Rating: 300 mA minimum
• Package Format: 0402 (1005 Metric) surface mount
• Core Material: Ceramic unshielded construction
• DC Resistance: Maximum allowable DCR for the application
• Environmental Compliance: RoHS3 compliance and MSL rating

The substitute part LRC0402CS2N2GV001T from Johanson Technology Inc. meets all primary electrical and mechanical requirements. Variations in DC resistance (160mOhm vs. 130mOhm) and self-resonant frequency (12GHz vs. 6GHz) remain within acceptable engineering tolerances for this component category and do not preclude functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The LRC0402CS2N2GV001T represents a direct functional equivalent for the obsolete CI100505-2N2D. Both components share identical inductance values, current ratings, package dimensions, and core material specifications. The substitute part carries active product status with confirmed inventory availability, ensuring supply chain continuity.

Both parts maintain ROHS3 compliance and MSL Level 1 ratings, satisfying regulatory and environmental requirements. The substitute exhibits a higher maximum DC resistance (160mOhm vs. 130mOhm) and extended self-resonant frequency (12GHz vs. 6GHz), characteristics that do not compromise functional performance in standard RF and high-frequency applications within the specified current and temperature operating ranges.

The maximum seated height differential of 0.002" (0.05mm) between the two components remains negligible for PCB assembly and layout considerations in 0402 form factor applications.

Frequently Asked Questions (FAQ)

Q: Can the LRC0402CS2N2GV001T be used as a direct replacement for the CI100505-2N2D?

A: Yes. Both components share identical inductance values (2.2 nH), current ratings (300 mA), package format (0402 Metric), and core material (ceramic unshielded). The substitute part is electrically and mechanically compatible for standard applications.

Q: What is the significance of the DCR difference between the two parts?

A: The CI100505-2N2D specifies 130mOhm maximum DCR, while the LRC0402CS2N2GV001T specifies 160mOhm maximum. This 30mOhm variance represents a 23% increase in resistance. Applications sensitive to resistive losses should evaluate this parameter against specific circuit requirements.

Q: Does the higher self-resonant frequency of the substitute part affect compatibility?

A: The LRC0402CS2N2GV001T exhibits a self-resonant frequency of 12GHz compared to 6GHz for the original part. This extended frequency response does not degrade performance and may provide improved characteristics in high-frequency applications. No compatibility issues arise from this parameter difference.

Q: Are there temperature range considerations when substituting?

A: The CI100505-2N2D operates from -55°C to 105°C, while the LRC0402CS2N2GV001T operates from -55°C to 100°C. The substitute part has a 5°C lower maximum temperature rating. Applications requiring operation above 100°C must retain the original component or identify alternative substitutes.

Q: What is the impact of the 0.002" height difference on PCB assembly?

A: The seated height difference of 0.002" (0.05mm) is negligible for standard surface mount assembly processes and does not require PCB layout modifications. Both components conform to 0402 (1005 Metric) specifications.

Q: Why is the original CI100505-2N2D listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The LRC0402CS2N2GV001T, with active product status and substantial inventory availability, provides supply continuity for designs currently using the Bourns component.
