Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK107AB7105KAHT is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Capacitance: 1 µF
• Tolerance: ±10%
• Voltage Rating: 25V
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C ~ 125°C
• Package: 0603 (1608 Metric)
• Mounting Type: Surface Mount, MLCC
• Automotive Rating: AEC-Q200
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1

All identified substitute parts meet these criteria without exception. Physical dimensions (length, width, and thickness) remain within acceptable tolerances for direct board-level substitution. Electrical performance characteristics are identical across all substitute candidates.

Parameter Comparison

Engineering Selection Recommendations

MCAST168AB7105KTNA01 (Taiyo Yuden): This part is manufactured by the same supplier as the main component and carries Active product status. It meets all electrical and mechanical specifications with identical capacitance, voltage rating, temperature coefficient, and operating range. The thickness specification is 0.035" (0.90mm) compared to the main part's 0.037" (0.95mm), representing a reduction within acceptable tolerance for surface mount assembly. AEC-Q200 automotive rating and ROHS3 compliance are maintained. This substitute is suitable for direct replacement in existing designs.

CGA3E1X7R1E105K080AC (TDK Corporation): This part is manufactured by TDK Corporation and carries Active product status. All electrical parameters match the main component identically. Physical dimensions and thickness specifications are equivalent to the MCAST168AB7105KTNA01. AEC-Q200 automotive certification and ROHS3 compliance are present. This substitute provides cross-manufacturer equivalence and is suitable for direct replacement.

Both substitute parts are qualified for automotive applications with AEC-Q200 certification, ensuring reliability in the intended application environment. Selection between substitutes may be based on supplier availability, inventory levels, or established procurement relationships.

Frequently Asked Questions (FAQ)

Q: Can MCAST168AB7105KTNA01 be used as a direct replacement for TMK107AB7105KAHT?

A: Yes. Both parts share identical electrical specifications (1 µF, ±10%, 25V, X7R, -55°C ~ 125°C), identical package dimensions (0603/1608 Metric), and equivalent automotive ratings (AEC-Q200). The thickness difference (0.035" vs 0.037") is within acceptable tolerance for surface mount assembly.

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

A: MCAST168AB7105KTNA01 is manufactured by Taiyo Yuden, the same manufacturer as the main part. CGA3E1X7R1E105K080AC is manufactured by TDK Corporation. Both meet identical electrical and mechanical specifications. The selection between them depends on supplier availability and procurement strategy.

Q: Are both substitute parts suitable for automotive applications?

A: Yes. Both MCAST168AB7105KTNA01 and CGA3E1X7R1E105K080AC carry AEC-Q200 certification and are rated for automotive applications, matching the main component's qualification level.

Q: Does the thickness difference between parts affect board assembly?

A: No. The thickness variation (0.035" to 0.037") is within standard tolerance for 0603 package ceramic capacitors and does not affect surface mount assembly processes or board-level compatibility.

Q: Are all parts RoHS compliant?

A: Yes. The main part and both substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements.

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

A: This designation indicates the TMK107AB7105KAHT has been superseded by the manufacturer. The substitute parts with Active status represent the current product line equivalents and are recommended for ongoing production and new applications.

Q: Can these parts be used interchangeably in existing inventory?

A: Yes. All three parts are electrically and mechanically equivalent within specified tolerances and can be used interchangeably in applications designed for the TMK107AB7105KAHT.
