Substitute Part Grouping Explanation

Substitution of the EMK107B7474MA-T is determined by the following criteria:

Direct Equivalents maintain identical electrical specifications: 0.47 µF capacitance, ±20% tolerance, 16V voltage rating, X7R temperature coefficient, and 0603 (1608 Metric) package. These parts are interchangeable without circuit redesign.

Tolerance Upgrades provide tighter capacitance tolerance (±10% or ±5%) while maintaining all other electrical parameters. These parts are electrically compatible and offer improved precision.

Voltage Upgrades increase the rated voltage (25V or 50V) while maintaining 0.47 µF capacitance and X7R characteristics. These parts are backward compatible in circuits designed for 16V operation.

Manufacturer Alternatives from KEMET, TDK Corporation, and KYOCERA AVX provide equivalent specifications from different suppliers, enabling multi-source procurement strategies.

All substitute parts share the following critical parameters with the main part:

Capacitance: 0.47 µF
Temperature Coefficient: X7R
Package: 0603 (1608 Metric)
Mounting Type: Surface Mount, MLCC
Operating Temperature: -55°C ~ 125°C

Engineering Selection Recommendations

Direct Equivalents for Immediate Replacement:

C0603C474M4RAC7867 (KEMET) and C1608X7R1C474M080AC (TDK Corporation) are direct electrical equivalents with identical 0.47 µF ±20% 16V specifications. KEMET's C0603C474M4RAC7867 holds Active product status, making it suitable for new designs. TDK's part is marked "Not For New Designs" but remains electrically compatible.

Tolerance-Improved Alternatives:

EMK107B7474KA-T (Taiyo Yuden), C0603C474K4RAC7867 (KEMET), and 06033C474KAT2A (KYOCERA AVX) provide ±10% tolerance at 16V or 25V ratings. These parts maintain full electrical compatibility while offering tighter capacitance control. C0603C474J4RAC7867 (KEMET) offers ±5% tolerance for applications requiring superior precision.

Voltage-Upgraded Options:

TMK107B7474KA-TR (Taiyo Yuden, 25V) and UMK107B7474KA-TR (Taiyo Yuden, 50V) provide higher voltage ratings with ±10% tolerance. These parts are backward compatible in 16V circuits and offer design margin for voltage transient protection.

Active Product Status Priority:

For new designs, prioritize KEMET parts (C0603C474M4RAC7867, C0603C474J4RAC7867, C0603C474K4RAC7867) and KYOCERA AVX parts (KGM15BR71C474MT, 06033C474KAT2A, 06033C474MAT2A), which maintain Active product status. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can I substitute EMK107B7474MA-T with a part having different tolerance?

A: Yes. Parts with ±10% or ±5% tolerance are electrically compatible and provide improved precision. The main part's ±20% tolerance is the maximum allowable variance; tighter tolerances are acceptable substitutes in all applications.

Q: Are voltage-upgraded parts (25V, 50V) compatible with a 16V circuit design?

A: Yes. Higher voltage-rated capacitors are backward compatible in circuits designed for lower voltages. A 25V or 50V rated capacitor operates safely in a 16V application and provides additional design margin against voltage transients.

Q: What is the difference between Taiyo Yuden EMK, TMK, and UMK series?

A: These are Taiyo Yuden's internal series designations. EMK indicates 16V rating, TMK indicates 25V rating, and UMK indicates 50V rating. All share identical 0.47 µF capacitance, X7R temperature coefficient, and 0603 package specifications.

Q: Can I use KEMET, TDK, or KYOCERA AVX parts as direct replacements?

A: Yes. All listed parts from these manufacturers meet the same electrical specifications (0.47 µF, X7R, 0603 package, -55°C to 125°C operating range) and are mechanically compatible. Verify PCB assembly equipment compatibility with specific part dimensions if required.

Q: Why do some parts show "Not For New Designs" status?

A: This designation indicates the manufacturer has released newer versions or improved alternatives. However, these parts remain fully functional and are suitable for replacement, repair, and legacy design support. For new product development, prioritize parts with Active status.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Standard PCB assembly processes are sufficient; no baking or dry-pack storage is required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference are ROHS3 compliant, meeting EU Restriction of Hazardous Substances requirements.
