MEM2012P101RT001 Equivalent & Substitute Parts

Part Overview

The MEM2012P101RT001 is a 3rd order LC (Pi) EMI filter designed for low-pass filtering applications in data line circuits for mobile devices. This surface mount component operates at a 100 MHz cutoff frequency with 20 dB attenuation in the 1.5 GHz to 2 GHz band, supporting up to 200 mA current at 12V rated voltage.

The MEM2012P101RT001 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MEM2012P101RT001 is determined by strict equivalence across the following critical parameters:

• Filter technology: LC (Pi) topology
• Filter order: 3rd order
• Cutoff frequency: 100 MHz
• Attenuation performance: 20 dB @ 1.5 GHz ~ 2 GHz
• Current capacity: 200 mA
• Voltage rating: 12V
• Operating temperature range: -40°C ~ 85°C
• Package form factor: 0805 (2012 Metric), 3 PC Pad
• Physical dimensions: 2.00 mm x 1.25 mm footprint
• Compliance: ROHS3 Compliant, MSL 1

The MEM2012F101RT001 meets all these criteria and is classified as an active product from the same manufacturer and series.

Parameter Comparison

Engineering Selection Recommendations

The MEM2012F101RT001 is the direct substitute for the obsolete MEM2012P101RT001. Both components are manufactured by TDK Corporation within the MEM series and share identical electrical and mechanical specifications across all critical parameters.

The MEM2012F101RT001 carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and MSL 1 rating, meeting environmental and moisture handling requirements for mobile device applications.

The height differential of 0.05 mm (0.95 mm versus 1.00 mm) falls within standard PCB assembly tolerances and does not affect functional performance or board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MEM2012F101RT001 be used as a direct replacement for the MEM2012P101RT001?

A: Yes. Both components are electrically and mechanically equivalent across all specified parameters, including filter order, cutoff frequency, attenuation performance, current rating, voltage rating, operating temperature range, package form factor, and physical dimensions.

Q: What is the difference between the MEM2012P101RT001 and MEM2012F101RT001?

A: The primary difference is product status. The MEM2012P101RT001 is obsolete, while the MEM2012F101RT001 is active. The MEM2012F101RT001 has a maximum height of 1.00 mm compared to 0.95 mm for the MEM2012P101RT001. This 0.05 mm difference is within standard PCB assembly tolerances.

Q: Are there packaging differences between these parts?

A: The MEM2012P101RT001 packaging is not specified in the provided data. The MEM2012F101RT001 is supplied in Tape & Reel (TR) format. Both components use the 0805 (2012 Metric), 3 PC Pad package form factor with identical footprints.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MEM2012P101RT001 and MEM2012F101RT001 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both carry EAR99 ECCN classification and 8548.00.0000 HTSUS code.

Q: What applications are these filters designed for?

A: Both components are specified for data line filtering in mobile device applications, providing 3rd order low-pass EMI filtering at 100 MHz cutoff frequency with 20 dB attenuation in the 1.5 GHz to 2 GHz band.
