Key Parameters

Substitute Part Grouping Explanation

Substitution of ceramic capacitors is determined by electrical and mechanical compatibility across the following parameters:

Critical Parameters for Substitution:

• Capacitance value (0.047 µF)
• Tolerance (±10%)
• Temperature coefficient (X5R)
• Package / Case (0603 / 1608 Metric)
• Physical dimensions (0.063" L x 0.031" W x 0.035" Max thickness)
• Operating temperature range (-55°C ~ 85°C)
• Mounting type (Surface Mount, MLCC)

Voltage Rating Considerations: Substitute parts may have equal or higher voltage ratings than the main part. A higher voltage rating maintains electrical compatibility while providing additional design margin.

Compliance Parameters: All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and general industrial applications.

Parameter Comparison

Engineering Selection Recommendations

MCAST168SB5473KTNA01 (Direct Equivalent)

This part is the recommended direct substitute for TMK107BJ473KAHT. It maintains identical electrical specifications (0.047 µF, ±10%, 25V, X5R) and physical dimensions (0603 package). The MCAST168SB5473KTNA01 carries Active product status from Taiyo Yuden, making it suitable for new designs and ongoing production. All compliance certifications (AEC-Q200, ROHS3, MSL 1) are maintained.

GMK107BJ473KAHT (Voltage Upgrade)

This Taiyo Yuden part provides a 35V voltage rating while maintaining all other electrical and mechanical parameters. The higher voltage rating provides additional design margin in applications where the 25V rating may approach circuit operating conditions. This part is classified as "Not For New Designs" but remains available for legacy design support.

CGA3E2X5R1H473K080AA (Voltage Upgrade)

This TDK Corporation part offers the highest voltage rating at 50V with identical capacitance, tolerance, temperature coefficient, and package specifications. The 50V rating provides maximum design margin for voltage transient protection. This part is classified as "Not For New Designs" but is available for applications requiring enhanced voltage headroom.

Frequently Asked Questions (FAQ)

Q: Can MCAST168SB5473KTNA01 be used as a direct replacement for TMK107BJ473KAHT?

A: Yes. Both parts share identical electrical specifications (0.047 µF, ±10%, 25V, X5R) and physical dimensions (0603 package). The MCAST168SB5473KTNA01 is the direct equivalent and is the preferred choice for new designs due to its Active product status.

Q: What is the difference between the main part and the upgrade options?

A: The main part (TMK107BJ473KAHT) and upgrade options (GMK107BJ473KAHT and CGA3E2X5R1H473K080AA) differ only in voltage rating: 25V, 35V, and 50V respectively. All other parameters—capacitance, tolerance, temperature coefficient, package, and operating temperature—remain identical. Higher voltage ratings provide additional design margin but do not change the capacitive behavior.

Q: Are all substitute parts automotive-qualified?

A: Yes. All parts listed carry AEC-Q200 certification, confirming automotive qualification. All parts are ROHS3 compliant and have MSL 1 rating (unlimited moisture sensitivity).

Q: Can I use a higher voltage-rated part in place of the 25V specification?

A: Yes. A capacitor with a higher voltage rating is electrically compatible with circuits designed for lower voltage ratings. The higher voltage rating does not affect capacitance value or performance in the circuit; it only provides additional voltage margin.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the manufacturer has superseded the part in their product line. However, the part remains available for existing production and legacy design support. For new designs, the Active-status MCAST168SB5473KTNA01 is recommended.

Q: Are the physical dimensions identical across all substitute parts?

A: Yes. All parts use the 0603 (1608 Metric) package with dimensions of 0.063" L x 0.031" W and maximum thickness of 0.035" (0.90mm). They are mechanically interchangeable on PCBs designed for 0603 components.

Q: What packaging options are available?

A: TMK107BJ473KAHT is supplied in Tape & Reel (TR) packaging. MCAST168SB5473KTNA01 is supplied in Tape & Reel (TR). GMK107BJ473KAHT is supplied in Cut Tape (CT) & Digi-Reel®. CGA3E2X5R1H473K080AA is supplied in Tape & Reel (TR). Packaging selection depends on production volume and assembly requirements.
