Substitute Part Grouping Explanation

Substitution of the MMASE105SB7473MFNA01 is determined by strict equivalence across the following parameters: capacitance value (0.047 µF), tolerance (±20%), rated voltage (16V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package type (0402/1005 Metric), physical dimensions, mounting type (Surface Mount MLCC), moisture sensitivity level (MSL 1), and RoHS compliance status (ROHS3).

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts that match all electrical and mechanical specifications of the main part, differing only in manufacturer or internal series designation. These parts are direct functional replacements.

Upgrade Equivalents: Parts that meet or exceed all parametric requirements of the main part while offering additional certifications or enhanced reliability ratings (such as AEC-Q200 automotive qualification). These parts are suitable for applications requiring higher assurance levels.

Engineering Selection Recommendations

MSASE105SB7473MFNA01 (Taiyo Yuden): This parametric equivalent maintains identical electrical and mechanical specifications to the main part while offering significantly higher inventory availability (20,772 pieces versus 731 pieces). Both parts are manufactured by Taiyo Yuden and carry ROHS3 compliance. Selection of this part is appropriate when supply continuity is a priority and application requirements do not mandate specific series designation.

CGA2B2X7R1C473M050BA (TDK Corporation): This upgrade equivalent meets all parametric requirements of the main part and includes AEC-Q200 automotive qualification. Selection of this part is appropriate for applications requiring automotive-grade reliability assurance or when automotive supply chain qualification is mandated. This part carries ROHS3 compliance and REACH Unaffected status.

C0402C473M4RAC7867 (KEMET): This parametric equivalent maintains identical electrical and mechanical specifications to the main part. The part is designated for bypass and decoupling applications and carries ROHS3 compliance and REACH Unaffected status. Inventory availability is 13,360 pieces. Selection of this part is appropriate when KEMET sourcing is preferred or when application-specific decoupling performance is required.

All substitute parts are active in production, carry ROHS3 compliance, and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can MSASE105SB7473MFNA01 be used as a direct replacement for MMASE105SB7473MFNA01?

A: Yes. Both parts are manufactured by Taiyo Yuden and share identical electrical specifications (0.047 µF, ±20%, 16V, X7R, -55°C ~ 125°C), mechanical dimensions (0402/1005 Metric), and compliance ratings (ROHS3, MSL 1). The parts differ only in series designation (MSAS versus MMAS) and application classification (General Purpose versus Medical, Non-Critical).

Q: What is the difference between the main part and the TDK CGA2B2X7R1C473M050BA substitute?

A: The CGA2B2X7R1C473M050BA is a parametric equivalent that meets all electrical and mechanical requirements of the main part. The primary distinction is the inclusion of AEC-Q200 automotive qualification rating, which the main part does not carry. This qualification indicates enhanced reliability testing and suitability for automotive applications.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts are packaged in 0402 (1005 Metric) format with identical physical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum thickness (0.022" / 0.55mm). All parts are surface mount MLCCs with identical mounting type and lead configuration, ensuring PCB footprint compatibility.

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

A: MSL 1 (Unlimited) indicates that these components have unlimited shelf life and do not require moisture bake-out procedures prior to soldering. This rating applies to all listed parts and ensures compatibility with standard manufacturing workflows without special moisture control requirements.

Q: Can the KEMET C0402C473M4RAC7867 be used in medical applications?

A: The KEMET part is designated for bypass and decoupling applications and carries ROHS3 compliance and REACH Unaffected status. Application suitability is determined by circuit requirements and design specifications rather than part designation alone. The electrical and mechanical parameters are identical to the main part.

Q: What is the difference between parametric equivalents and upgrade equivalents?

A: Parametric equivalents match all electrical and mechanical specifications of the main part but may differ in manufacturer, series, or application classification. Upgrade equivalents meet or exceed all parametric requirements while offering additional certifications or enhanced reliability ratings, such as AEC-Q200 automotive qualification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, ensuring compatibility with regulatory requirements for restricted substances in electrical and electronic equipment.
