Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the MMASU105SCG080DFNA01?

A: A part qualifies as a substitute when it matches all mandatory parameters: 8 pF capacitance, ±0.5pF tolerance, 50V voltage rating, C0G/NP0 temperature coefficient, -55°C to 125°C operating range, 0402 (1005 Metric) package, and identical physical dimensions (0.039" L x 0.020" W, 0.022" max thickness). All listed substitutes meet these criteria.

Q: What is the difference between Upgrade and Parametric Equivalent substitutes?

A: Upgrade substitutes carry AEC-Q200 automotive qualification, indicating enhanced reliability testing and suitability for automotive applications. Parametric Equivalent substitutes meet all electrical and mechanical specifications but lack automotive qualification and are rated for general purpose or legacy applications.

Q: Can I use C1005C0G1H080D050BA in new designs?

A: No. The C1005C0G1H080D050BA carries a "Not For New Designs" product status. This part is available for legacy design support and existing production runs only. For new designs, select from parts with "Active" product status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the primary MMASU105SCG080DFNA01 part.

Q: What is Moisture Sensitivity Level 1?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts share this MSL rating.

Q: Which substitute has the highest inventory availability?

A: The CL05C080DB51PNC (Samsung Electro-Mechanics) offers the largest inventory position with 600,100 units in stock, followed by C1005C0G1H080D050BA (TDK Corporation) with 149,377 units.

Q: Can I mix different substitute manufacturers in the same production run?

A: Yes. All substitute parts are parametrically equivalent and meet identical electrical and mechanical specifications. However, verify your design documentation and quality procedures permit multi-source component usage.

Q: What does REACH Unaffected mean?

A: REACH Unaffected designation indicates the component is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements, simplifying compliance documentation for European markets.

Q: Are the physical dimensions identical across all substitutes?

A: Yes. All substitute parts share identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) with 0.022" (0.55mm) maximum thickness. They are mechanically interchangeable in 0402 (1005 Metric) footprints.
