Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK107ABJ225MA-T is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

• Capacitance: 2.2 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature Coefficient: X5R (exact match required)
• Operating Temperature Range: -55°C ~ 85°C (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Parameter Allowing Substitution:

• Voltage Rating: Parts rated at 25V or higher are acceptable substitutes, as higher voltage ratings provide equivalent or superior performance in circuits designed for 25V operation.

Substitute parts are grouped into two categories:

1. Parametric Equivalents (25V Rating): Parts with identical electrical specifications and voltage rating to the main part. These provide direct replacement capability.

2. Upgrade Substitute (50V Rating): Parts with identical electrical specifications but higher voltage rating. These provide enhanced voltage margin in the same physical package.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Existing Designs:

The MSAST168AB5225MTNA01 (Taiyo Yuden) and 0603X225M250CT (Walsin Technology Corporation) are parametric equivalents with identical electrical specifications and 25V voltage rating. Both parts are designated as Active products, providing long-term availability assurance compared to the Not For New Designs status of the main part. Both are ROHS3 compliant with MSL 1 rating.

For New Design Implementation:

The UMK107BBJ225MA-T (Taiyo Yuden) provides an upgrade substitute with 50V voltage rating while maintaining all other electrical and mechanical parameters. This part accommodates higher voltage margins in circuit design. Although designated as Not For New Designs, it offers superior voltage specification. The parametric equivalents MSAST168AB5225MTNA01 and 0603X225M250CT are preferred for new designs due to Active product status.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements. All parts are classified under ECCN EAR99 and HTSUS 8532.24.0020.

Frequently Asked Questions (FAQ)

Q: Can the MSAST168AB5225MTNA01 be used as a direct replacement for TMK107ABJ225MA-T?

A: Yes. The MSAST168AB5225MTNA01 is a parametric equivalent with identical capacitance (2.2 µF), tolerance (±20%), voltage rating (25V), temperature coefficient (X5R), operating temperature range (-55°C ~ 85°C), package (0603), and moisture sensitivity level (1). Physical dimensions and thickness are identical. The part is manufactured by Taiyo Yuden with Active product status.

Q: What is the difference between the parametric equivalents and the upgrade substitute?

A: The parametric equivalents (MSAST168AB5225MTNA01 and 0603X225M250CT) match the main part's 25V voltage rating exactly. The upgrade substitute (UMK107BBJ225MA-T) provides a 50V voltage rating while maintaining all other specifications. The 50V rating allows operation in circuits with higher voltage margins. Maximum thickness increases from 0.037" to 0.039" for the upgrade substitute.

Q: Are there any physical compatibility concerns when substituting these parts?

A: All substitute parts use the 0603 (1608 Metric) package with identical length and width dimensions (0.063" L x 0.031" W). The upgrade substitute UMK107BBJ225MA-T has a maximum thickness of 0.039" compared to 0.037" for other parts. This 0.002" difference must be evaluated for clearance in specific PCB layouts.

Q: Which substitute part should be selected for new product designs?

A: The MSAST168AB5225MTNA01 or 0603X225M250CT are recommended for new designs due to their Active product status, ensuring long-term availability. Both maintain identical electrical specifications to the main part with 25V voltage rating.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The MSAST168AB5225MTNA01 and 0603X225M250CT also carry REACH Unaffected status.

Q: What is the significance of the X5R temperature coefficient?

A: X5R temperature coefficient indicates the capacitor maintains stable capacitance across the operating temperature range of -55°C to 85°C. All substitute parts maintain this specification, ensuring consistent performance across the full temperature range.

Q: Can the 0603X225M250CT from Walsin Technology Corporation be used interchangeably with Taiyo Yuden parts?

A: Yes. The 0603X225M250CT is a parametric equivalent with identical electrical specifications, package, and compliance ratings. It is manufactured by a different supplier but meets all substitution criteria for the TMK107ABJ225MA-T.
