MEM2012D201R Equivalent & Substitute Parts

Part Overview

The MEM2012D201R is a 2nd order LC EMI filter manufactured by TDK Corporation, designed for low-pass filtering applications in data line circuits for mobile devices. This component operates at a 200 MHz cutoff frequency with 20 dB attenuation across the 800 MHz to 2 GHz band, supporting 200 mA current at 25V rated voltage in a compact 0805 (2012 Metric) surface mount package.

The MEM2012D201R is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MEM2012D201R is determined by the following critical parameters that must remain consistent:

• Filter Characteristics: 2nd order low-pass LC technology with 200 MHz cutoff frequency
• Electrical Performance: 200 mA current capacity and compatible voltage rating
• Channel Configuration: Single-channel design
• Operating Environment: Temperature range -40°C ~ 85°C
• Application Domain: Data line filtering for mobile devices
• Mounting Standard: Surface mount technology

The substitute part MEM1608D201RT001 maintains functional equivalence through identical filter order, technology type, cutoff frequency, current rating, temperature range, and application classification. Differences in package size (0603 vs 0805), voltage rating (6.3V vs 25V), and product status (Active vs Obsolete) are secondary considerations that do not prevent substitution when design constraints permit.

Parameter Comparison

Engineering Selection Recommendations

The MEM1608D201RT001 is the designated manufacturer substitute for the obsolete MEM2012D201R. Selection of this substitute is supported by the following factors:

Product Status: The MEM1608D201RT001 maintains Active product status, ensuring long-term availability and continued manufacturer support, whereas the MEM2012D201R is classified as Obsolete.

Compliance & Certifications: Both parts share identical REACH status (REACH Unaffected) and ECCN classification (EAR99). The MEM1608D201RT001 carries RoHS3 compliance certification, meeting current regulatory requirements for electronic components.

Functional Equivalence: Identical filter order (2nd), cutoff frequency (200 MHz), current capacity (200 mA), and operating temperature range (-40°C ~ 85°C) ensure functional compatibility in data line filtering applications.

Physical Constraints: The MEM1608D201RT001 occupies a smaller footprint (0603 vs 0805 package) and reduced height (0.70 mm vs 0.85 mm), which may require PCB layout verification but generally provides design flexibility.

Voltage Rating Consideration: The MEM1608D201RT001 is rated at 6.3V compared to the 25V rating of the MEM2012D201R. Circuit voltage requirements must be evaluated to confirm compatibility with the lower voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the MEM1608D201RT001 directly replace the MEM2012D201R on existing PCBs?

A: Direct PCB replacement requires layout modification due to package size differences (0805 to 0603). The smaller footprint of the MEM1608D201RT001 necessitates updated pad patterns and trace routing. Electrical functionality remains equivalent.

Q: What is the significance of the LC (T-Type) designation in the substitute part?

A: The T-Type configuration indicates a specific internal topology variant of the LC filter. Both the standard LC and LC (T-Type) technologies maintain the same 2nd order low-pass filtering characteristics and 200 MHz cutoff frequency required for this application.

Q: Is the 6.3V voltage rating of the MEM1608D201RT001 sufficient for circuits designed for 25V operation?

A: The voltage rating specifies the maximum voltage the component can withstand. If your circuit operates at voltages exceeding 6.3V, the MEM1608D201RT001 is not suitable. Verify actual circuit voltage requirements before substitution.

Q: What packaging format differences exist between these parts?

A: The MEM2012D201R is supplied in bulk packaging, while the MEM1608D201RT001 is supplied in Tape & Reel (TR) format. This affects procurement and assembly processes but does not impact component performance.

Q: Are both parts suitable for mobile device data line applications?

A: Both parts are specified for data line filtering in mobile devices. The identical cutoff frequency, current capacity, and operating temperature range confirm functional suitability for this application domain.

Q: What is the MSL rating and why is it relevant?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.
