Substitute Part Grouping Explanation

Substitution for the LT063D475MAT2X is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 4.7 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 25V (exact match required)
• Temperature Coefficient: X5R (exact match required)
• Operating Temperature Range: -55°C ~ 85°C (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

Two direct substitutes meet all these criteria and are qualified for direct replacement in applications currently using the LT063D475MAT2X.

Parameter Comparison

Engineering Selection Recommendations

C1206C475M3PAC7800 (KEMET) is the primary recommended substitute. This part maintains Active product status, ensuring long-term availability and manufacturer support. All electrical specifications match the LT063D475MAT2X exactly, with full ROHS3 compliance and MSL 1 rating. The increased thickness (0.071" vs 0.040") is within standard PCB assembly tolerances and does not affect electrical performance or board-level compatibility.

C3216X5R1E475M160AA (TDK Corporation) is a qualified secondary substitute with identical electrical specifications and compliance certifications. However, this part carries a "Not For New Designs" status, indicating TDK has discontinued active development for this model. While suitable for replacement in existing applications, it is not recommended for new product designs due to potential future supply constraints.

Both substitutes are electrically and mechanically interchangeable with the LT063D475MAT2X in 1206 package footprints. Selection between them should prioritize the KEMET part for new designs and ongoing production due to its Active status.

Frequently Asked Questions (FAQ)

Q: Can C1206C475M3PAC7800 be used as a direct replacement for LT063D475MAT2X?

A: Yes. Both parts share identical capacitance (4.7 µF), tolerance (±20%), voltage rating (25V), temperature coefficient (X5R), operating temperature range (-55°C ~ 85°C), package (1206), and compliance certifications. The physical footprint is identical, and both are rated MSL 1. The thickness difference (0.071" vs 0.040") does not affect PCB assembly or electrical performance.

Q: Why is C3216X5R1E475M160AA marked "Not For New Designs"?

A: This designation indicates TDK has transitioned this model out of active production. While the part remains electrically and mechanically equivalent to the LT063D475MAT2X, future availability cannot be guaranteed. For new product designs, the KEMET C1206C475M3PAC7800 is the preferred choice due to its Active status.

Q: Are there any thermal or performance differences between these substitutes?

A: No. All three parts share the same X5R temperature coefficient and -55°C ~ 85°C operating range. Capacitance stability and performance across temperature are equivalent. The thickness variation does not impact electrical characteristics.

Q: What is the significance of MSL 1 rating for these parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture baking requirements. All three parts carry this rating, meaning they can be stored and handled under standard conditions without special moisture control procedures.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. The 1206 package footprint is standardized across all three parts. No PCB layout modifications are required for substitution. The increased thickness of the KEMET and TDK parts is within standard component height tolerances for surface mount assembly.
