Key Parameters

Substitute Part Grouping Explanation

Substitution of the EMK107BC6475MA-T is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Capacitance: 4.7 µF (exact match required)
• Voltage Rating: 16V (exact match required)
• Temperature Coefficient: X6S (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)

Secondary Compatibility Factors:

• Tolerance: ±20% (main part specification; ±10% represents improved tolerance and is acceptable as upgrade)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Parts are grouped into two categories: Upgrade substitutes (improved tolerance specifications) and Parametric Equivalents (identical electrical and mechanical specifications). All substitute parts maintain identical physical dimensions, thermal characteristics, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

EMK107BC6475KA-T (Upgrade Substitute)

The EMK107BC6475KA-T is a direct upgrade substitute with identical electrical and mechanical specifications except for improved tolerance (±10% versus ±20%). This part is manufactured by Taiyo Yuden and maintains the same series designation (M). Although classified as "Not For New Designs," it provides superior tolerance performance for applications requiring tighter capacitance control. Selection of this part is appropriate when tolerance improvement is beneficial and inventory availability permits.

MSASE168BC6475MTNA01 (Parametric Equivalent)

The MSASE168BC6475MTNA01 is a parametric equivalent manufactured by Taiyo Yuden with identical electrical and mechanical specifications, including ±20% tolerance. This part carries "Active" product status, indicating ongoing manufacturer support and availability. The MSASE series represents the current production line for this capacitance and voltage rating. This part is the preferred selection for new designs and long-term supply chain continuity.

C1608X6S1C475M080AC (Parametric Equivalent)

The C1608X6S1C475M080AC is a parametric equivalent manufactured by TDK Corporation with identical electrical and mechanical specifications, including ±20% tolerance. This part is classified as "Not For New Designs" but provides cross-manufacturer equivalence. Selection of this part is appropriate when Taiyo Yuden parts are unavailable and multi-source qualification is required. The part features Low ESL characteristics and is suitable for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can EMK107BC6475KA-T replace EMK107BC6475MA-T in existing designs?

A: Yes. The EMK107BC6475KA-T is electrically and mechanically equivalent with improved tolerance specification (±10% versus ±20%). All critical parameters including capacitance, voltage rating, temperature coefficient, package dimensions, and operating temperature range are identical. Direct substitution is permissible.

Q: What is the difference between the substitute parts listed?

A: EMK107BC6475KA-T is an upgrade substitute with tighter tolerance. MSASE168BC6475MTNA01 and C1608X6S1C475M080AC are parametric equivalents with identical specifications to the main part. MSASE168BC6475MTNA01 carries Active product status, while C1608X6S1C475M080AC is from an alternative manufacturer (TDK Corporation).

Q: Are all substitute parts available in the same packaging options?

A: No. EMK107BC6475MA-T and MSASE168BC6475MTNA01 are supplied in Tape & Reel (TR) packaging. EMK107BC6475KA-T is supplied in Cut Tape (CT) & Digi-Reel® packaging. C1608X6S1C475M080AC is supplied in Tape & Reel (TR) packaging. Packaging selection must align with assembly process requirements.

Q: Which substitute part should be selected for new designs?

A: MSASE168BC6475MTNA01 is the recommended selection for new designs due to its Active product status and ongoing manufacturer support. This part ensures long-term availability and supply chain stability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the regulatory compliance of the main part.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the packaging format is compatible with the assembly equipment. All parts share identical 0603 (1608 Metric) package dimensions and surface mount characteristics. Tape & Reel and Cut Tape formats require different feeder configurations but result in identical mounted components.

Q: What is the significance of the X6S temperature coefficient?

A: X6S temperature coefficient specifies capacitance variation across the operating temperature range of -55°C to 105°C. All listed parts maintain this specification, ensuring consistent performance across the full operating temperature range. This characteristic is critical for SMPS filtering applications.
