Frequently Asked Questions (FAQ)

Q: Can I substitute the MLAST31LAB7106MTNA01 with any of the listed parts?

A: Yes. All listed parts meet the mandatory equivalence criteria: 10 µF capacitance, ±20% tolerance, 25V rating, X7R temperature coefficient, -55°C to 125°C operating range, 1206 (3216 Metric) package, surface mount MLCC mounting type, MSL 1, and RoHS3 compliance. Electrical and mechanical compatibility is guaranteed.

Q: What is the difference between "Active" and "Not For New Designs" parts?

A: "Active" parts are in current production and recommended for new circuit designs. "Not For New Designs" parts are legacy products still available for inventory but not recommended for new applications. For new designs, select from the Active status parts: MLAST31LAB7106MTNA01, C1206C106M3RACAUTO, C1206C106M3RAC7800, GRM31CR71E106MA12K, or KGM31AR71E106MU.

Q: Does the 1206 package dimension match across all substitutes?

A: Yes. All substitute parts use the 1206 (3216 Metric) package with identical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.071" (1.80mm). PCB footprints and assembly processes are fully compatible.

Q: Are there any application-specific differences between substitutes?

A: The primary specification (MLAST31LAB7106MTNA01) is rated for medical and non-critical applications. Substitute parts have varying application designations: KEMET C1206C106M3RACAUTO includes AEC-Q200 automotive qualification; KEMET C1206C106M3RAC7800 is specified for bypass and decoupling; TDK parts include features such as Low ESL or Soft Termination; Murata and KYOCERA AVX parts are general purpose. All meet the core electrical specifications and can be used interchangeably from an electrical standpoint.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life and no special moisture bake-out requirements before soldering. All parts in this reference carry MSL 1 rating, eliminating moisture sensitivity concerns during storage and assembly.

Q: Are all parts RoHS3 compliant?

A: Yes. All parts listed are ROHS3 compliant, meeting current environmental and hazardous substance restrictions. No lead or other restricted substances are present.

Q: Which substitute has the highest inventory availability?

A: The TDK Corporation C3216X7R1E106M160AB has the highest inventory at 36866 units. However, this part is marked "Not For New Designs." For active production parts, Murata Electronics GRM31CR71E106MA12K offers the highest availability at 21105 units.
