MMAST063SCG201JFNA01 Equivalent & Substitute Parts

Part Overview

The MMAST063SCG201JFNA01 is a 200 pF ceramic capacitor rated at 25V with C0G/NP0 temperature coefficient, manufactured by Taiyo Yuden in 0201 (0603 Metric) surface mount package. This component is currently in active production status and is suitable for medical and non-critical applications. Substitute parts are identified when equivalent electrical and mechanical specifications are required but the original part becomes unavailable or when alternative sourcing is necessary due to inventory or supply chain considerations.

Substitute Part Grouping Explanation

Substitution of the MMAST063SCG201JFNA01 is based on strict equivalence of the following electrical and mechanical parameters:

Capacitance Value: 200 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 25V (exact match required)
Temperature Coefficient: C0G/NP0 (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)
Package Type: 0201 (0603 Metric) surface mount (exact match required)
Physical Dimensions: 0.024" L x 0.012" W, 0.013" max thickness (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute part TMK063CG201JTHF meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Engineering Selection Recommendations

Primary Selection: MMAST063SCG201JFNA01 is the recommended choice for new designs. This part maintains active production status and is suitable for medical and non-critical applications with full compliance to ROHS3 standards.

Substitute Selection: TMK063CG201JTHF provides complete electrical and mechanical equivalence and is suitable for replacement in existing applications where the primary part is unavailable. However, this part carries a "Not For New Designs" status and is rated for automotive applications under AEC-Q200 certification. The substitute part should be used only for legacy system support or when the primary part cannot be sourced.

Both parts are manufactured by Taiyo Yuden and share identical electrical specifications, package dimensions, and environmental compliance ratings. Selection between these parts should be based on product lifecycle requirements and application-specific certifications rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can TMK063CG201JTHF be used as a direct replacement for MMAST063SCG201JFNA01?

A: Yes. Both parts are electrically and mechanically identical with matching capacitance (200 pF), tolerance (±5%), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (0201/0603 Metric), and physical dimensions. They are pin-compatible and functionally interchangeable.

Q: What is the difference between these two part numbers?

A: The primary differences are product lifecycle status and application focus. MMAST063SCG201JFNA01 is in active production for medical and non-critical applications. TMK063CG201JTHF is designated "Not For New Designs" and carries AEC-Q200 automotive certification. Both parts meet ROHS3 compliance and have identical electrical and mechanical specifications.

Q: Are there any package or mounting differences?

A: No. Both parts use identical 0201 (0603 Metric) surface mount packages with dimensions of 0.024" L x 0.012" W and maximum thickness of 0.013" (0.33mm). They are suitable for the same PCB layouts and reflow processes.

Q: What does "Not For New Designs" mean for the substitute part?

A: This designation indicates that TMK063CG201JTHF is in mature or declining production phase. While the part remains available and fully functional, Taiyo Yuden recommends using MMAST063SCG201JFNA01 for new product development. The substitute part is appropriate for maintaining existing products or addressing temporary supply constraints.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions and no special storage or handling requirements.

Q: Do both parts meet RoHS compliance?

A: Yes. Both MMAST063SCG201JFNA01 and TMK063CG201JTHF are ROHS3 compliant.
