Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MEM2012T75R0 is determined by the following critical parameters:

• Filter Technology & Order: Must be LC (T-Type) 3rd order low-pass configuration
• Package Compatibility: Must use 0805 (2012 Metric) surface mount package with 3 PC pad configuration
• Electrical Ratings: Current capacity must be ≥ 250 mA; voltage rating must be ≥ 10V
• Operating Temperature: Must support -40°C ~ 85°C range
• Channel Configuration: Must be single-channel (1 channel)
• Application Suitability: Must be suitable for data line filtering in mobile device applications

The MEM2012S101RT001 qualifies as a direct substitute based on matching all critical parameters while offering enhanced performance characteristics through a higher cutoff frequency (100 MHz) and improved attenuation (30 dB @ 400 MHz ~ 2 GHz).

• Performance Enhancement: The MEM2012S101RT001 provides superior attenuation characteristics (30 dB versus 20 dB) and a higher cutoff frequency (100 MHz versus 75 MHz), offering improved filtering performance for data line applications.

Frequently Asked Questions (FAQ)

Q: Can the MEM2012S101RT001 be used as a direct replacement for the MEM2012T75R0 on existing PCBs?

A: Yes. Both components use identical 0805 (2012 Metric) surface mount packages with 3 PC pad configurations. No PCB layout modifications are required for substitution.

Q: What is the primary difference between these two filters?

A: The MEM2012S101RT001 has a higher cutoff frequency (100 MHz versus 75 MHz) and provides greater attenuation (30 dB versus 20 dB) across its operating range. The substitute offers enhanced filtering performance while maintaining all other electrical and mechanical specifications.

Q: Are the electrical ratings identical between the two parts?

A: Yes. Both components are rated for 250 mA current, 10V voltage, and operate across the -40°C to 85°C temperature range. Moisture sensitivity level (MSL 1) is also identical.

Q: Does the MEM2012S101RT001 meet current regulatory standards?

A: Yes. The MEM2012S101RT001 is ROHS3 compliant and maintains REACH unaffected status, meeting current environmental regulations for electronic components.

Q: Why is the MEM2012T75R0 listed as obsolete?

A: The MEM2012T75R0 has been discontinued by TDK Corporation. The MEM2012S101RT001 represents the active production alternative within the MEM series for equivalent filtering applications.
