MEM2012P50R0 Equivalent & Substitute Parts

Part Overview

The MEM2012P50R0 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 50 MHz cutoff frequency with 20 dB attenuation across the 400 MHz to 2 GHz range, supporting 200 mA current at 12V rated voltage in a compact 0805 (2012 Metric) surface mount package.

The MEM2012P50R0 carries an Obsolete product status. 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 MEM2012P50R0 is determined by strict equivalence across the following critical parameters:

• Filter technology and order: LC (Pi) topology, 3rd order configuration
• Electrical performance: 50 MHz cutoff frequency, 20 dB attenuation @ 400 MHz ~ 2 GHz
• Current and voltage ratings: 200 mA at 12V
• Physical form factor: 0805 (2012 Metric) surface mount package with 3 PC pad configuration
• Operating temperature range: -40°C ~ 85°C
• Single-channel architecture
• Low-pass filter classification

The MEM2012F50R0T001 meets all these criteria and is classified as the manufacturer-recommended substitute. This part maintains identical electrical specifications and mechanical compatibility while offering Active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The MEM2012F50R0T001 is the direct substitute for the obsolete MEM2012P50R0. Both parts are manufactured by TDK Corporation and share identical electrical and mechanical specifications across all critical parameters.

Selection of the MEM2012F50R0T001 is supported by:

• Active product status ensuring long-term availability and supply chain stability
• ROHS3 compliance certification meeting current environmental regulations
• Identical filter performance characteristics and package footprint
• Tape & Reel packaging format suitable for automated assembly processes
• Marginal height increase (0.039" vs 0.030") remains within standard PCB assembly tolerances for 0805 components

The height differential of 0.009" (0.24 mm) does not affect electrical performance or standard surface mount assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can MEM2012F50R0T001 be used as a direct replacement for MEM2012P50R0 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. The MEM2012F50R0T001 maintains the same 50 MHz cutoff frequency, 20 dB attenuation profile, 200 mA current rating, and 0805 (2012 Metric) package footprint. No circuit modifications are required.

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

A: The MEM2012F50R0T001 has a maximum height of 0.039" (1.00 mm) compared to 0.030" (0.76 mm) for the MEM2012P50R0. This 0.009" (0.24 mm) difference is within standard tolerances for 0805 surface mount components and does not impact PCB assembly, clearance, or electrical performance.

Q: Why is MEM2012P50R0 marked as Obsolete?

A: Obsolete status indicates the part is no longer manufactured. The MEM2012F50R0T001 is the active equivalent and should be used for new designs and component replenishment.

Q: Does packaging format affect electrical performance?

A: No. The MEM2012F50R0T001 is supplied in Tape & Reel (TR) format for automated assembly, while the MEM2012P50R0 was supplied in bulk packaging. Packaging format does not affect component electrical characteristics or performance.

Q: Are there compliance differences between these parts?

A: The MEM2012F50R0T001 carries ROHS3 compliance certification. Both parts maintain REACH Unaffected status. The ROHS3 compliance of the substitute part aligns with current environmental and regulatory requirements.
