TMK107BJ104KAHT Equivalent & Substitute Parts

Part Overview

The TMK107BJ104KAHT is a 0.1 µF ±10% 25V ceramic capacitor in 0603 (1608 Metric) package manufactured by Taiyo Yuden. This multilayer ceramic capacitor (MLCC) features X5R temperature coefficient and is rated for automotive applications with AEC-Q200 compliance. The part is designated as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Identifying equivalent and substitute parts is necessary for ongoing production support, maintenance applications, and design flexibility when the primary part becomes unavailable or when design requirements necessitate alternative voltage ratings or packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the TMK107BJ104KAHT is based on the following critical parameters:

Direct Substitutes (Same Electrical Specifications): Parts that maintain identical capacitance (0.1 µF), tolerance (±10%), voltage rating (25V), temperature coefficient (X5R), and package (0603) are classified as direct substitutes. These parts are interchangeable without circuit redesign.

Voltage-Upgraded Substitutes (Higher Voltage Rating): Parts with identical capacitance, tolerance, temperature coefficient, and package but with higher voltage ratings (35V or 50V) are classified as upgrades. These parts are electrically compatible and physically interchangeable, with the benefit of increased voltage margin. Voltage upgrades do not require circuit modification.

Manufacturer Variants: Different manufacturers (Taiyo Yuden, TDK Corporation) producing parts with identical electrical and mechanical specifications are considered equivalent. Manufacturing process differences do not affect substitution eligibility when all specified parameters match.

Packaging Format Variants: Parts with identical electrical specifications but different packaging formats (Tape & Reel versus Cut Tape & Digi-Reel) are substitutable provided the assembly process can accommodate the packaging format.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Voltage Rating): MCAST168SB5104KTNA01 is the recommended direct substitute for TMK107BJ104KAHT. This part maintains all electrical specifications and is currently in Active product status, ensuring long-term availability. Both parts are manufactured by Taiyo Yuden, carry AEC-Q200 automotive certification, and are RoHS3 compliant. The MCAST168SB5104KTNA01 is suitable for applications requiring identical performance characteristics without circuit modification.

For Voltage-Upgraded Applications: GMK107BJ104KAHT (35V rating) and UMK107BJ104KAHT (50V rating) are suitable when circuit design permits higher voltage margins. These upgrades provide enhanced reliability in applications subject to voltage transients or when design margins require additional safety factor. Both maintain identical capacitance, tolerance, and temperature coefficient specifications.

For Cross-Manufacturer Substitution: CGA3E2X5R1E104K080AA (TDK Corporation, 25V) and CGA3E2X5R1H104K080AA (TDK Corporation, 50V) are equivalent alternatives from a different manufacturer. Both parts meet AEC-Q200 automotive requirements and RoHS3 compliance. Selection between Taiyo Yuden and TDK variants depends on supply chain considerations and established qualification protocols.

Packaging Format Consideration: GMK107BJ104KAHT is supplied in Cut Tape & Digi-Reel format, which may require different handling procedures compared to standard Tape & Reel packaging. Verify assembly equipment compatibility before selection.

Frequently Asked Questions (FAQ)

Q: Can TMK107BJ104KAHT be replaced with a higher voltage-rated part? A: Yes. UMK107BJ104KAHT (50V) and GMK107BJ104KAHT (35V) are electrically and mechanically compatible replacements. Higher voltage ratings do not affect circuit operation when the original design voltage requirement is 25V or lower. The capacitor will function identically with improved voltage margin.

Q: What is the difference between MCAST168SB5104KTNA01 and TMK107BJ104KAHT? A: Both parts are manufactured by Taiyo Yuden with identical electrical specifications (0.1 µF, ±10%, 25V, X5R, 0603 package). The primary difference is product status: MCAST168SB5104KTNA01 is Active, while TMK107BJ104KAHT is Not For New Designs. MCAST168SB5104KTNA01 is the recommended replacement for new production and long-term availability.

Q: Are TDK CGA series parts compatible with Taiyo Yuden TMK series? A: Yes. CGA3E2X5R1E104K080AA (TDK, 25V) and CGA3E2X5R1H104K080AA (TDK, 50V) are functionally equivalent to their Taiyo Yuden counterparts when electrical specifications match. Both manufacturers' parts carry AEC-Q200 certification and RoHS3 compliance. Selection depends on supply chain strategy and internal qualification requirements.

Q: Does packaging format affect substitution eligibility? A: Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) does not affect electrical or mechanical compatibility. However, assembly equipment must support the selected packaging format. Verify that pick-and-place equipment can accommodate the packaging variant before production implementation.

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. While the part remains functional and available, it is not recommended for new product development. For ongoing production of existing designs, direct substitutes with Active status (such as MCAST168SB5104KTNA01) are preferred to ensure long-term supply continuity.

Q: Can these parts be used interchangeably in automotive applications? A: Yes, all listed substitute parts carry AEC-Q200 automotive certification and are suitable for automotive applications. Substitution does not require re-qualification provided the electrical specifications remain within design requirements and the parts maintain identical package dimensions and mounting characteristics.

Q: What is Moisture Sensitivity Level (MSL) 1? A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts have MSL 1 rating, meaning they can be stored and handled without special moisture control procedures, simplifying inventory management and reducing production constraints.
