Engineering Selection Recommendations

TMK316B7225MLHT (25V Rating)

This part carries "Not For New Designs" status. It remains suitable for ongoing production support and maintenance applications where the 25V rating meets circuit requirements. The component maintains full AEC-Q200 automotive qualification and ROHS3 compliance.

GMK316B7225MLHT (35V Rating)

This substitute provides a 35V voltage rating while maintaining all other electrical and mechanical specifications. The higher voltage rating offers increased design margin for circuits operating below 35V. This part is also designated "Not For New Designs" and carries ROHS3 compliance with AEC-Q200 qualification.

UMK316B7225MLHT (50V Rating)

This substitute provides a 50V voltage rating with identical capacitance, tolerance, temperature coefficient, and package dimensions. The 50V rating offers maximum design margin for applications requiring higher voltage headroom. This part is designated "Not For New Designs" and carries ROHS3 compliance with AEC-Q200 qualification.

All three parts are manufactured by Taiyo Yuden, maintain identical physical footprints, and are suitable for direct PCB layout compatibility. Selection between these parts depends on the maximum voltage requirement of the specific circuit application.

Frequently Asked Questions (FAQ)

Q: Can GMK316B7225MLHT or UMK316B7225MLHT be used as direct replacements for TMK316B7225MLHT?

A: Yes. Both substitute parts maintain identical capacitance (2.2 µF), tolerance (±20%), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package dimensions (1206 / 3216 Metric), and compliance certifications (ROHS3, AEC-Q200). The higher voltage ratings (35V and 50V respectively) are compatible with circuits designed for 25V operation.

Q: What is the primary difference between these three parts?

A: The voltage rating is the only electrical parameter that differs. TMK316B7225MLHT is rated 25V, GMK316B7225MLHT is rated 35V, and UMK316B7225MLHT is rated 50V. All other specifications remain identical.

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

A: Yes. All three parts use the 1206 (3216 Metric) package with dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.071" (1.80mm). They are mechanically interchangeable on PCB layouts.

Q: Do all three parts meet automotive qualification requirements?

A: Yes. All three parts carry AEC-Q200 qualification and ROHS3 compliance, making them suitable for automotive applications.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: Can these parts be used in SMPS filtering applications?

A: Yes. All three parts are specified for SMPS filtering applications and feature ultra-low ESR characteristics suitable for this use.

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

A: This product status designation indicates these parts are mature products no longer recommended for new design implementations. However, they remain available for production support of existing designs and applications.
