Key Parameters

Substitute Part Grouping Explanation

Substitution of the CIG22H2R2MAE is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 2.2 µH
• Inductance tolerance: ±20%
• Current rating: 1.2 A minimum
• Package format: 1008 (2520 Metric)
• Shielding type: Shielded
• Operating temperature range: -40°C ~ 125°C minimum
• Surface mount configuration

Acceptable Variation Parameters:

• DC resistance: Substitute parts with lower DCR values are acceptable (117mOhm is lower than 138mOhm, representing improved performance)
• Product status: Active parts are preferred over obsolete parts for new supply sourcing
• Inductance test frequency: Variation in test frequency does not disqualify substitution when inductance value and tolerance are matched

The TDK Corporation MLP2520S2R2MT0S1 meets all mandatory matching criteria and represents a direct functional equivalent with improved DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MLP2520S2R2MT0S1 from TDK Corporation is a direct functional equivalent to the obsolete CIG22H2R2MAE. Both components share identical inductance specifications, current ratings, package dimensions, and thermal operating ranges. The TDK substitute offers improved DC resistance performance at 117mOhm maximum compared to the Samsung part's 138mOhm specification, resulting in lower power dissipation in circuit applications.

The TDK part maintains active product status, ensuring long-term availability and supply chain reliability. Both components satisfy ROHS3 compliance requirements and carry identical moisture sensitivity ratings. Physical footprint compatibility is confirmed across all dimensional parameters, enabling direct PCB layout substitution without design modification.

Selection of the MLP2520S2R2MT0S1 is supported by regulatory compliance alignment and improved electrical performance characteristics within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the MLP2520S2R2MT0S1 be used as a direct replacement for CIG22H2R2MAE in existing designs?

A: Yes. Both components share identical inductance values (2.2 µH ±20%), current ratings (1.2 A), package dimensions (1008/2520 Metric), and operating temperature ranges (-40°C ~ 125°C). Physical footprint and electrical performance are compatible for direct PCB substitution.

Q: What is the significance of the lower DC resistance in the TDK part?

A: The MLP2520S2R2MT0S1 specifies 117mOhm maximum DCR compared to 138mOhm for the Samsung part. Lower DC resistance reduces resistive losses and heat generation during operation, representing improved performance within the same current rating envelope.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity ratings, and are REACH unaffected. Regulatory and environmental compliance profiles are equivalent.

Q: Why is product status relevant to this substitution?

A: The CIG22H2R2MAE is classified as obsolete, indicating discontinued manufacturing and limited remaining inventory. The MLP2520S2R2MT0S1 maintains active status, ensuring sustained availability for current and future production requirements.

Q: Do the different inductance test frequencies affect substitution suitability?

A: No. The CIG22H2R2MAE is tested at 1 MHz while the MLP2520S2R2MT0S1 is tested at 2 MHz. Both components meet the specified 2.2 µH inductance value with ±20% tolerance at their respective test frequencies. The inductance value specification takes precedence over test frequency variation.

Q: Are there any package or mounting considerations for this substitution?

A: Both parts use identical 1008 (2520 Metric) surface mount packages with matching dimensions (2.50mm L x 2.00mm W x 1.00mm H maximum). No PCB layout or assembly process modifications are required.
