MEM2012P25R0 Equivalent & Substitute Parts

Part Overview

The MEM2012P25R0 is a 3rd order LC (Pi) EMI filter designed for low-pass filtering applications in data line circuits for mobile devices. This component operates at a 25 MHz cutoff frequency with 20 dB attenuation across the 300 MHz to 2 GHz range, supporting 200 mA current at 12V rated voltage in a compact 0805 (2012 Metric) surface mount package.

The MEM2012P25R0 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 MEM2012P25R0 is determined by strict equivalence across the following critical parameters:

• Filter Type: Low Pass
• Filter Order: 3rd
• Technology: LC (Pi)
• Number of Channels: 1
• Center / Cutoff Frequency: 25 MHz
• Attenuation Value: 20 dB @ 300 MHz ~ 2 GHz
• Current Rating: 200 mA
• Voltage - Rated: 12V
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 0805 (2012 Metric), 3 PC Pad
• Mounting Type: Surface Mount

The MEM2012F25R0T001 meets all these criteria and is classified as an active product from the same manufacturer series, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MEM2012F25R0T001 is the direct substitute for the obsolete MEM2012P25R0. Both components are manufactured by TDK Corporation within the MEM series and share identical electrical and mechanical specifications across all critical filtering parameters.

The MEM2012F25R0T001 offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. This component is ROHS3 compliant, meeting current regulatory requirements for electronic components in regulated markets.

The height difference of 0.009" (0.24 mm) between the two parts is within typical PCB assembly tolerances and does not affect functional performance or board-level compatibility in standard surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can MEM2012F25R0T001 be used as a direct replacement for MEM2012P25R0?

A: Yes. Both components are electrically and mechanically equivalent across all specified parameters including filter type, order, technology, frequency response, current rating, voltage rating, operating temperature range, and package dimensions.

Q: What is the significance of the height difference between these parts?

A: The MEM2012F25R0T001 has a maximum height of 0.039" (1.00 mm) compared to 0.030" (0.76 mm) for the MEM2012P25R0. This 0.009" (0.24 mm) difference is within standard PCB assembly clearance specifications and does not impact board-level integration or component functionality.

Q: Why is the MEM2012P25R0 listed as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The MEM2012F25R0T001 represents the current active equivalent within the same product series.

Q: What is the difference between bulk and Tape & Reel packaging?

A: The MEM2012P25R0 is supplied in bulk packaging, while the MEM2012F25R0T001 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and provides improved handling and component protection during manufacturing.

Q: Are there any compliance differences between these parts?

A: The MEM2012F25R0T001 is ROHS3 compliant, meeting current environmental and regulatory standards. Both components maintain REACH Unaffected status and are suitable for applications requiring compliance with current electronic component regulations.
