Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBASS31LAB7333KTNA01 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Capacitance: 0.033 µF
• Tolerance: ±10%
• Voltage Rating: 630V
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C ~ 125°C
• Package / Case: 1206 (3216 Metric)
• Physical Dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Thickness (Max): 0.071" (1.80mm)
• Mounting Type: Surface Mount, MLCC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are classified into two categories:

Upgrade Substitutes: Parts that maintain all electrical and mechanical parameters while offering enhanced product status (Active vs. Not For New Designs) or additional certifications (AEC-Q200 for automotive applications).

Parametric Equivalents: Parts that match all electrical and mechanical specifications but may differ in product status, packaging format, or specific application ratings while remaining functionally interchangeable.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Applications:

When new design implementations are required, selection should prioritize parts with Active product status designation. The following parts meet this criterion:

• CGA5L4X7R2J333K160AA (TDK Corporation): Active status with AEC-Q200 certification. Suitable for automotive and general purpose applications requiring automotive-grade reliability.

• GCJ31CR7LV333KW01K and GCJ31CR7LV333KW01L (Murata Electronics): Both Active status with AEC-Q200 certification and soft termination feature. Suitable for automotive and boardflex-sensitive applications.

• 885342208015 (Würth Elektronik): Active status with high voltage feature designation. Suitable for general purpose applications.

• CL31B333KHHSW6E (Samsung Electro-Mechanics): Active status with soft termination feature. Suitable for boardflex-sensitive applications.

For Automotive Applications:

When AEC-Q200 certification is a design requirement, the following parts are qualified:

• CGA5L4X7R2J333K160AA (TDK Corporation)
• GCJ31CR7LV333KW01K (Murata Electronics)
• GCJ31CR7LV333KW01L (Murata Electronics)
• SMK316AB7333KLHT (Taiyo Yuden) - Note: Not For New Designs status

For Legacy or Existing Design Support:

Parts with "Not For New Designs" status are suitable for replacement in existing production runs or legacy systems:

• SMK316AB7333KLHT (Taiyo Yuden): AEC-Q200 certified, higher inventory availability (3128 pcs).
• C3216X7R2J333K160AM (TDK Corporation): Highest inventory availability (104923 pcs), suitable for high-volume legacy applications.

For Supply Chain Optimization:

Inventory availability should be considered as a secondary factor after electrical and mechanical compatibility:

• C3216X7R2J333K160AM offers maximum availability (104923 pcs)
• GCJ31CR7LV333KW01K offers high availability (8548 pcs) with Active status and AEC-Q200 certification

Frequently Asked Questions (FAQ)

Q: Can I substitute MBASS31LAB7333KTNA01 with any of the listed equivalent parts?

A: Yes, all listed parts are electrically and mechanically equivalent. They share identical capacitance (0.033 µF), tolerance (±10%), voltage rating (630V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and package dimensions (1206/3216 Metric). Direct substitution is permissible from an electrical and mechanical standpoint.

Q: What is the difference between "Upgrade Substitutes" and "Parametric Equivalents"?

A: Upgrade Substitutes (CGA5L4X7R2J333K160AA, GCJ31CR7LV333KW01K, GCJ31CR7LV333KW01L, SMK316AB7333KLHT) maintain all electrical and mechanical parameters while offering enhanced product status or additional certifications such as AEC-Q200. Parametric Equivalents (885342208015, C3216X7R2J333K160AM, CL31B333KHHSW6E) match all specifications but may have different product status or application ratings.

Q: Does product status affect electrical performance?

A: No. Product status ("Active" vs. "Not For New Designs") indicates manufacturer support and availability for new designs, not electrical performance. Parts with "Not For New Designs" status are electrically and mechanically identical to Active parts and function identically in circuit applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, matching the primary part MBASS31LAB7333KTNA01.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates the lowest moisture sensitivity level. These parts do not require special moisture control during storage, handling, or assembly. All listed parts share this MSL rating.

Q: Which substitute part should I select for automotive applications?

A: For automotive applications, select parts with AEC-Q200 certification: CGA5L4X7R2J333K160AA (TDK), GCJ31CR7LV333KW01K (Murata), GCJ31CR7LV333KW01L (Murata), or SMK316AB7333KLHT (Taiyo Yuden). Among Active status parts, CGA5L4X7R2J333K160AA and the Murata GCJ series are recommended.

Q: What is the significance of "Soft Termination" feature?

A: Soft Termination is a manufacturing feature present in GCJ31CR7LV333KW01K, GCJ31CR7LV333KW01L (Murata), and CL31B333KHHSW6E (Samsung). This feature reduces mechanical stress on component terminations during thermal cycling and is beneficial for boardflex-sensitive applications. It does not affect electrical performance in standard applications.

Q: Can I use C3216X7R2J333K160AM as a direct replacement despite "Not For New Designs" status?

A: Yes, for existing production runs or legacy system support. C3216X7R2J333K160AM is electrically and mechanically identical and offers the highest inventory availability (104923 pcs). However, for new design implementations, Active status parts are recommended.

Q: Are there packaging format differences between substitute parts?

A: Most substitute parts are supplied in Tape & Reel (TR) format. CL31B333KHHSW6E is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are compatible with standard pick-and-place assembly equipment; format selection depends on production volume and assembly line configuration.

Q: What is the REACH status of these parts?

A: Multiple substitute parts carry "REACH Unaffected" designation (CGA5L4X7R2J333K160AA, GCJ31CR7LV333KW01K, GCJ31CR7LV333KW01L, C3216X7R2J333K160AM, CL31B333KHHSW6E), indicating compliance with REACH regulations. The primary part and some substitutes do not specify REACH status in available data.
