Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MEM2012TC100 is determined by the following critical parameters:

• Filter technology and order (LC T-Type, 3rd order)
• Single channel configuration
• Capacitance value (10pF)
• Current rating (1 A)
• Voltage rating (12V)
• Operating temperature range (-40°C ~ 85°C)
• Surface mount package form factor (0805/2012 Metric)
• Application compatibility (data line filtering for mobile devices)

The MEM2012SC100 meets all substitution criteria. Both parts share identical filter specifications, electrical ratings, and physical form factors. The primary differences are packaging format (Cut Tape vs. Tape & Reel) and pad configuration (3 PC vs. 6 PC), which do not affect functional equivalence. The MEM2012SC100 maintains active product status, providing long-term availability advantages.

Parameter Comparison

Engineering Selection Recommendations

The MEM2012SC100 is the direct functional equivalent for the obsolete MEM2012TC100. Selection of the MEM2012SC100 is supported by:

• Identical electrical specifications across all critical filter parameters
• Matching physical dimensions and surface mount form factor
• Active product status ensuring continued availability and supply chain stability
• ROHS3 compliance certification on the substitute part
• Equivalent moisture sensitivity level (MSL 1 - Unlimited)
• Identical REACH and ECCN classifications

The channel resistance differential (0.12 Ohms vs. 0.15 Ohms) represents a 0.03 Ohm variance and remains within acceptable engineering tolerance for EMI filter applications. The pad configuration difference (3 PC vs. 6 PC) reflects packaging methodology only and does not impact electrical performance or PCB layout compatibility for standard 0805 footprints.

Frequently Asked Questions (FAQ)

Q: Can MEM2012SC100 be used as a direct replacement for MEM2012TC100 in existing designs?

A: Yes. The MEM2012SC100 provides functional equivalence across all electrical and mechanical parameters. Both parts share identical filter specifications, current ratings, voltage ratings, and operating temperature ranges. PCB footprints remain compatible for standard 0805 (2012 Metric) surface mount layouts.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies individual components or small quantities cut from continuous tape. Tape & Reel packaging provides components on continuous tape wound on reels for automated assembly processes. Both packaging formats contain identical components; the difference is in supply and handling methodology.

Q: Does the pad configuration difference (3 PC vs. 6 PC) affect compatibility?

A: No. Pad configuration refers to the number of solder pads on the component package. Both 3 PC and 6 PC configurations are compatible with standard 0805 footprints. The difference does not impact electrical performance or PCB assembly compatibility.

Q: Why is the MEM2012TC100 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The MEM2012SC100 remains in active production and provides equivalent functionality, making it the appropriate choice for new designs and ongoing component procurement.

Q: Is the 0.03 Ohm resistance difference between parts significant?

A: No. The channel resistance variance (0.12 Ohms to 0.15 Ohms) is within acceptable engineering tolerance for EMI filter applications and does not affect circuit performance or signal integrity in data line filtering applications.
