Parameter Comparison

Engineering Selection Recommendations

GMK325B7475MNHTR (Taiyo Yuden Upgrade): This part is a direct upgrade from the main part number, maintaining the same manufacturer (Taiyo Yuden) and series designation (M). The voltage rating is increased from 25V to 35V, providing enhanced voltage margin while preserving all other electrical and mechanical specifications. Both parts carry "Not For New Designs" status and AEC-Q200 automotive qualification. This substitute is suitable for applications requiring higher voltage headroom within the same design envelope.

CC1210MKX7R8BB475 (YAGEO Direct Equivalent): This part provides electrical and mechanical equivalence to the main part number with identical 25V voltage rating and 4.7 µF capacitance. Manufactured by YAGEO, it carries Active product status, indicating ongoing production support. The CC series designation differs from the TMK series, but all critical parameters match the original specification. This substitute is suitable for applications where manufacturer diversification or active product status is required. YAGEO CC1210MKX7R8BB475 does not carry AEC-Q200 automotive qualification; applications requiring automotive-grade certification should reference the Taiyo Yuden alternatives.

Frequently Asked Questions (FAQ)

Q: Can GMK325B7475MNHTR replace TMK325B7475MNHT in existing designs?

A: Yes. The GMK325B7475MNHTR is a direct substitute with identical capacitance, tolerance, temperature coefficient, operating temperature range, package dimensions, and mounting characteristics. The increased voltage rating (35V vs. 25V) is compatible with all applications designed for the 25V part, as higher voltage-rated capacitors operate safely at lower applied voltages.

Q: What is the difference between the upgrade part and the direct equivalent?

A: GMK325B7475MNHTR is a Taiyo Yuden part with 35V rating (upgrade voltage). CC1210MKX7R8BB475 is a YAGEO part with 25V rating (direct voltage match). Both are mechanically and electrically compatible. The YAGEO part has Active product status, while the Taiyo Yuden upgrade maintains "Not For New Designs" status.

Q: Are all substitute parts qualified to AEC-Q200 automotive standards?

A: GMK325B7475MNHTR and TMK325B7475MNHT both carry AEC-Q200 qualification. CC1210MKX7R8BB475 does not list AEC-Q200 qualification. For automotive applications requiring AEC-Q200 compliance, use Taiyo Yuden parts only.

Q: Will the substitute parts fit the same PCB footprint?

A: Yes. All substitute parts use the 1210 (3225 Metric) package with identical physical dimensions (0.126" L x 0.098" W / 3.20mm x 2.50mm) and maximum thickness (0.083" / 2.10mm). PCB footprints and assembly processes require no modification.

Q: Can I use CC1210MKX7R8BB475 in place of TMK325B7475MNHT for SMPS filtering applications?

A: CC1210MKX7R8BB475 matches all electrical specifications (4.7 µF, ±20%, 25V, X7R, -55°C ~ 125°C) and is suitable for general-purpose applications. However, the original part is specified for automotive and SMPS filtering with AEC-Q200 qualification. For automotive SMPS applications, Taiyo Yuden parts are recommended.

Q: What is the moisture sensitivity level, and does it affect storage or handling?

A: All listed parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity. These parts do not require special moisture-controlled storage or baking procedures prior to assembly.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TMK325B7475MNHT, GMK325B7475MNHTR, and CC1210MKX7R8BB475 are all ROHS3 compliant and suitable for applications subject to RoHS regulations.
