Frequently Asked Questions (FAQ)
Q: Can MLAST31LAB7106KTNA01 be directly replaced with any of the listed substitutes?
A: Yes. All listed substitute parts match the critical electrical specifications (10 µF, ±10%, 25V, X7R), mechanical dimensions (1206 package, 0.126" x 0.063" x 0.071" max), operating temperature range (-55°C ~ 125°C), and compliance requirements (ROHS3, MSL 1). Direct substitution is supported without circuit redesign.
Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?
A: Tape & Reel packaging supplies components on continuous carrier tape suitable for high-volume automated assembly. Cut Tape & Digi-Reel® packaging provides components in smaller quantities on cut tape segments, offering flexibility for lower-volume production or mixed-component assembly. Both formats are compatible with standard pick-and-place equipment.
Q: Why is GRT31CR71E106KE13L marked "Not For New Designs"?
A: This designation indicates the part is in mature or declining production phase. While it remains functionally equivalent and available in inventory (10,431 pieces), it should be used only for sustaining existing products or legacy system repairs. For new product development, select from Active status alternatives such as C3216X7R1E106K160AB, CL31B106KAHNFNE, or CC1206KFX7R8BB106.
Q: Are there differences in application suitability between substitutes?
A: The original MLAST31LAB7106KTNA01 is specified for Medical and Non-Critical applications. Substitute parts designated for General Purpose applications (MSAST31LAB7106KTNA01, C3216X7R1E106K160AB, CC1206KFX7R8BB106, CC1206KKX7R8BB106, CL31B106KAHNFNE, CL31B106KAHNNNE, CL31B106KAHSFNE) are suitable for standard industrial and consumer electronics. Parts with Automotive or AEC-Q200 ratings (C1206C106K3RACAUTO, CL31B106KAHVPNE, GRT31CR71E106KE13L) meet automotive reliability standards and are appropriate for automotive applications.
Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?
A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This rating applies to all listed parts and eliminates the need for dry-pack storage or baking procedures prior to assembly.
Q: Can substitutes be mixed within a single production batch?
A: Yes. All substitute parts are electrically and mechanically equivalent. However, for traceability and quality control purposes, maintaining consistent part sourcing within a production batch is recommended. If multiple suppliers are used, ensure documentation reflects the specific manufacturer part number used in each assembly.
Q: What is the significance of X7R temperature coefficient?
A: X7R temperature coefficient specifies capacitance variation across the operating temperature range of -55°C ~ 125°C. X7R rated parts maintain capacitance within ±15% across this full range, making them suitable for applications requiring stable performance across wide temperature variations. All listed substitutes maintain this specification.
