EMK105BJ474MP-F Equivalent & Substitute Parts

Part Overview

The EMK105BJ474MP-F is a 0.47 µF ceramic capacitor rated at 16V with X5R temperature coefficient, manufactured by Taiyo Yuden in 0402 (1005 Metric) surface mount package. This component is designated as "Not For New Designs," indicating it has reached end-of-life status. The part is commonly used in SMPS filtering applications where stable capacitance across temperature ranges and compact form factors are required. Due to its discontinued status, identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for ongoing production support and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the EMK105BJ474MP-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 0.47 µF (exact match)
• Voltage rating: 16V (minimum requirement; higher ratings acceptable)
• Tolerance: ±20% (matching tolerance class)
• Temperature coefficient: X5R (ensures identical temperature stability characteristics)
• Operating temperature range: -55°C ~ 85°C (minimum coverage required)

Mechanical Equivalence Requirements:

• Package: 0402 (1005 Metric) surface mount form factor
• Mounting type: Surface Mount, MLCC
• Physical dimensions compatible with 0402 footprint

Compliance Requirements:

• RoHS3 compliance (regulatory requirement match)
• Moisture Sensitivity Level 1 (handling compatibility)

The substitute part EMK105ABJ474MV-F meets all electrical and mechanical equivalence criteria. Both parts are manufactured by Taiyo Yuden and share identical capacitance, voltage, tolerance, temperature coefficient, and operating temperature specifications. Both are packaged in 0402 form factor with surface mount configuration. The primary difference lies in the thickness specification, which does not affect electrical performance or circuit functionality.

Engineering Selection Recommendations

Primary Substitute: EMK105ABJ474MV-F

The EMK105ABJ474MV-F is a direct electrical and functional equivalent to the EMK105BJ474MP-F. Both parts are manufactured by Taiyo Yuden and share identical electrical specifications: 0.47 µF capacitance, 16V voltage rating, ±20% tolerance, and X5R temperature coefficient with -55°C to 85°C operating range. Both are packaged in 0402 (1005 Metric) surface mount form factor and comply with ROHS3 environmental standards.

The substitute part exhibits a greater maximum thickness (0.024" versus 0.013"), which does not affect electrical performance or circuit operation. This dimensional difference is within standard manufacturing tolerances for ceramic capacitors and does not impact PCB assembly compatibility or component placement in standard 0402 footprints.

Both parts carry "Not For New Designs" status, indicating end-of-life designation. For applications requiring active production support, alternative sources or newer generation capacitors from Taiyo Yuden or other manufacturers with equivalent specifications should be evaluated through standard component qualification processes.

The EMK105ABJ474MV-F demonstrates significantly higher inventory availability (224,247 pieces) compared to the original part (815 pieces), making it the practical choice for ongoing supply requirements.

Frequently Asked Questions (FAQ)

Q: Can EMK105ABJ474MV-F be used as a direct replacement for EMK105BJ474MP-F in existing designs?

A: Yes. Both parts are electrically identical with matching capacitance (0.47 µF), voltage rating (16V), tolerance (±20%), temperature coefficient (X5R), and operating temperature range (-55°C to 85°C). Both use identical 0402 (1005 Metric) surface mount packaging. The substitute part is functionally equivalent for all SMPS filtering applications.

Q: What is the significance of the thickness difference between these parts?

A: The EMK105ABJ474MV-F has a maximum thickness of 0.024" (0.60mm) compared to 0.013" (0.33mm) for the EMK105BJ474MP-F. This difference does not affect electrical performance or standard PCB assembly processes. Both parts fit within the 0402 package specification and are compatible with standard pick-and-place equipment and reflow soldering profiles.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both EMK105BJ474MP-F and EMK105ABJ474MV-F are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating they meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Why are both parts marked "Not For New Designs"?

A: This designation indicates both parts have reached end-of-life status with Taiyo Yuden. While they remain functionally suitable for existing applications and maintenance production, they are not recommended for new product development. For new designs, current-generation ceramic capacitors with equivalent specifications should be selected.

Q: What is the inventory status for these parts?

A: The original part EMK105BJ474MP-F has limited inventory (815 pieces). The substitute EMK105ABJ474MV-F has substantially higher availability (224,247 pieces), making it the practical choice for ongoing production requirements.

Q: Are there any application limitations when using the substitute part?

A: No. The EMK105ABJ474MV-F is suitable for all applications specified for the original part, including SMPS filtering. Electrical performance, temperature stability, and voltage handling characteristics are identical across both parts.
