Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MEM2012TC220 is determined by the following critical parameters:

• Filter Technology & Order: Must be LC (T-Type) 3rd Order Low Pass configuration
• Capacitance Value: Must be 22pF
• Current Rating: Must support 1 A minimum
• Voltage Rating: Must be rated for 12V minimum
• Package / Case: Must be 0805 (2012 Metric) Surface Mount
• Operating Temperature Range: Must cover -40°C to 85°C
• Number of Channels: Must be single channel (1)
• Application Compatibility: Data line filtering for mobile devices

The substitute part MEM2012SC220T001 meets all critical substitution criteria while maintaining functional equivalence in the MEM series from TDK Corporation.

Parameter Comparison

Engineering Selection Recommendations

The MEM2012SC220T001 serves as the primary substitute for the obsolete MEM2012TC220. Both components are manufactured by TDK Corporation within the MEM series and maintain identical electrical specifications for filter technology, order, capacitance, current rating, voltage rating, and operating temperature range.

The MEM2012SC220T001 carries a "Not For New Designs" status and includes ROHS3 compliance certification, providing regulatory alignment for current manufacturing environments. The substitute part is available in Tape & Reel packaging format, supporting automated assembly processes.

Physical differences exist in pad configuration (6 PC Pad versus 3 PC Pad) and component height (0.037" versus 0.030"), which require PCB layout verification to ensure mechanical compatibility. The channel resistance differential (0.15 Ohms versus 0.12 Ohms) remains within acceptable tolerances for data line filtering applications.

Frequently Asked Questions (FAQ)

Q: What makes MEM2012SC220T001 a valid substitute for MEM2012TC220?

A: Both components share identical filter technology (LC T-Type 3rd Order), capacitance value (22pF), current rating (1A), voltage rating (12V), operating temperature range (-40°C to 85°C), and 0805 (2012 Metric) package footprint. These parameters define functional equivalence for data line EMI filtering applications.

Q: Are there PCB layout considerations when switching from MEM2012TC220 to MEM2012SC220T001?

A: Yes. The substitute part features a different pad configuration (6 PC Pad versus 3 PC Pad) and increased height (0.037" versus 0.030"). PCB layout must be verified to accommodate the pad pattern and clearance requirements of the substitute component.

Q: Does the channel resistance difference affect circuit performance?

A: The MEM2012SC220T001 has a channel resistance of 0.15 Ohms compared to 0.12 Ohms in the MEM2012TC220. This 0.03 Ohm differential is within acceptable tolerances for data line filtering and does not compromise functional performance in the specified application.

Q: What is the significance of the "Not For New Designs" status on the substitute part?

A: This status indicates that while MEM2012SC220T001 remains available for existing designs and legacy support, TDK Corporation does not recommend it for new product development. For new designs, consult TDK's current MEM series offerings.

Q: Is the substitute part RoHS compliant?

A: Yes. MEM2012SC220T001 is ROHS3 compliant. The main part specification does not include RoHS status information.

Q: What packaging formats are available for the substitute part?

A: MEM2012SC220T001 is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly operations.
