Substitute Part Grouping Explanation

Substitute parts are organized into two categories based on electrical parameter compatibility:

Upgrade Substitutes - Parts with identical capacitance, tolerance, temperature coefficient, and package, but with higher voltage ratings. These parts are direct functional upgrades suitable for applications where the original 16V rating is insufficient. Voltage derating is not required when substituting with higher-rated parts.

Parametric Equivalents - Parts with identical electrical specifications (2.2 µF, ±20%, 16V, X7R) and mechanical package (1206), but from different manufacturers or product series. These parts maintain full compatibility with the original design while offering alternative sourcing options.

Substitution eligibility is determined by the following criteria:

Capacitance value: 2.2 µF (exact match required)
Tolerance: ±20% (exact match required)
Temperature Coefficient: X7R (exact match required)
Package / Case: 1206 (3216 Metric) (exact match required)
Voltage Rating: Equal to or greater than 16V
Mounting Type: Surface Mount, MLCC (exact match required)
AEC-Q200 Automotive Qualification (required)
RoHS3 Compliance (required)

MAASE31LSB7225MTNA01, MCASE31LSB7225MTNA01, C1206C225M4RECAUTO, and C1206C225M4RECAUTO7210 are suitable for direct replacement of EMK316B7225MLHT. These parts maintain identical electrical specifications and package dimensions. MAASE31LSB7225MTNA01 and MCASE31LSB7225MTNA01 are Taiyo Yuden products with Active product status, providing continuity within the same manufacturer ecosystem. C1206C225M4RECAUTO and C1206C225M4RECAUTO7210 are KEMET equivalents with Active product status, offering alternative sourcing from a qualified automotive supplier. All candidates carry AEC-Q200 qualification and ROHS3 compliance.

For Voltage Margin Applications (Upgrade Substitutes)

GMK316B7225MLHT (35V) and UMK316B7225MLHT (50V) are Taiyo Yuden upgrade options providing higher voltage ratings while maintaining identical capacitance, tolerance, and package specifications. These parts are suitable for applications requiring voltage derating margin or operating in higher voltage environments. Both maintain AEC-Q200 qualification and ROHS3 compliance. UMK316B7225MLHT offers the highest voltage rating at 50V with the largest available inventory (10,516 pcs).

Product Status Consideration

EMK316B7225MLHT, GMK316B7225MLHT, and UMK316B7225MLHT are designated Not For New Designs.

Frequently Asked Questions (FAQ)

Q: Can GMK316B7225MLHT or UMK316B7225MLHT be used as direct replacements for EMK316B7225MLHT?

A: Yes. Both parts are direct functional upgrades with identical capacitance (2.2 µF), tolerance (±20%), temperature coefficient (X7R), and package (1206). The higher voltage ratings (35V and 50V respectively) do not prevent substitution in circuits designed for 16V operation. No circuit modifications are required.

Q: What is the difference between MAASE31LSB7225MTNA01 and MCASE31LSB7225MTNA01?

A: Both parts are parametric equivalents to EMK316B7225MLHT with identical electrical specifications and package. The difference lies in their product series designation (MAAS versus MCAS). Both are Taiyo Yuden products with Active status. Selection between these parts is based on availability and supply chain requirements.

Q: Are KEMET C1206C225M4RECAUTO and C1206C225M4RECAUTO7210 interchangeable?

A: Yes. Both KEMET parts are parametric equivalents with identical electrical specifications (2.2 µF, ±20%, 16V, X7R) and package (1206). The designation suffix "7210" in C1206C225M4RECAUTO7210 indicates a specific tape and reel configuration. Both parts are suitable for direct substitution of EMK316B7225MLHT.

Q: Do all substitute parts meet automotive qualification requirements?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification and ROHS3 compliance, matching the original EMK316B7225MLHT specifications. This ensures suitability for automotive applications.

Q: What is the moisture sensitivity level for all listed parts?

A: All parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements. No special storage or handling procedures are necessary.

Q: Can I use a 35V or 50V rated capacitor in a circuit designed for 16V?

A: Yes. Higher voltage-rated capacitors operate safely in lower voltage applications. The voltage rating indicates the maximum voltage the capacitor can withstand; operating at lower voltages presents no reliability concerns. Upgrade substitutes GMK316B7225MLHT and UMK316B7225MLHT are suitable for any application originally specified for EMK316B7225MLHT.

Q: Are there any dimensional differences between substitute parts?

A: No. All substitute parts maintain identical package specifications: 1206 (3216 Metric) with dimensions 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.071" (1.80mm). All parts are surface mount MLCCs with identical footprints.

Q: Why is EMK316B7225MLHT marked as Not For New Designs?

A: This designation indicates the part is in mature or end-of-life status. For new design implementations, Active-status equivalents such as MAASE31LSB7225MTNA01, MCASE31LSB7225MTNA01, C1206C225M4RECAUTO, or C1206C225M4RECAUTO7210 are recommended to ensure long-term manufacturer support and availability.
