Tolerance: ±20% (exact match required)
Voltage Rating: 25V (exact match required)
Temperature Coefficient: X7R (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)
Package / Case: 0603 (1608 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Physical Dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.035" (0.90mm) maximum thickness (exact match required)

Frequently Asked Questions (FAQ)

Q: Can the TMF107B7474MAHT be directly replaced with MAAST168SB7474MTNA01?

A: Yes. Both parts are identical in capacitance (0.47 µF), tolerance (±20%), voltage rating (25V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package (0603), and physical dimensions. Direct substitution is valid without circuit modification.

Q: What is the difference between MCJCT168BB7474MTPA01 and MAAST168SB7474MTNA01?

A: Both parts are electrically and mechanically equivalent. The MCJCT168BB7474MTPA01 includes Soft Termination feature and supports Boardflex Sensitive applications, making it suitable for flex circuit environments. The MAAST168SB7474MTNA01 is the standard equivalent without these additional features.

Q: Can I use cross-manufacturer substitutes such as TDK CGA3E3X7R1E474M080AB or Murata GCM188R71E474MA64D?

A: Yes, provided your design has been qualified for cross-manufacturer substitution. All listed alternatives maintain identical electrical specifications (0.47 µF, ±20%, 25V, X7R, -55°C ~ 125°C) and mechanical package (0603). Cross-manufacturer substitution requires verification of existing design qualification or new qualification testing per your quality procedures.

Q: Why is the TMF107B7474MAHT marked as "Not For New Designs"?

A: This designation indicates the part has been superseded by newer product lines within Taiyo Yuden's portfolio. The MAAST168SB7474MTNA01 is the recommended replacement for new designs. Existing inventory of TMF107B7474MAHT remains available for legacy production support.

Q: Are all substitute parts AEC-Q200 rated?

A: Yes. All substitute parts listed maintain AEC-Q200 automotive qualification, ensuring compliance with automotive reliability standards.

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

A: MSL 1 indicates Moisture Sensitivity Level 1, meaning the component has unlimited shelf life without moisture bake-out requirements. All listed parts share this rating, eliminating moisture management concerns during storage and handling.

Q: Can I mix manufacturers in the same production batch?

A: Mixing manufacturers is technically valid from an electrical and mechanical standpoint, as all parts are parametrically equivalent. However, manufacturing and supply chain practices typically require single-source parts per production batch to maintain traceability and consistency. Consult your quality and procurement procedures for multi-source part handling requirements.

Q: What inventory levels should I consider for supply chain planning?

A: CGA3E3X7R1E474M080AB (TDK) offers the highest inventory (11247 pcs), followed by MCJCT168BB7474MTPA01 (Taiyo Yuden, 1111 pcs) and C0603C474M3RACAUTO7411 (KEMET, 1003 pcs). Inventory levels should be evaluated against your production volume and lead time requirements.
