Engineering Selection Recommendations

The ZXMP6A18KTC is a direct parametric equivalent to the ZXMP6A18KQTC. Both devices are manufactured by Diodes Incorporated and share identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts is based on availability and inventory status rather than functional differences.

Both parts maintain Active product status and are RoHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and use. The ZXMP6A18KTC offers higher inventory availability (9320 pieces) compared to the ZXMP6A18KQTC (1051 pieces), which may influence procurement decisions for high-volume applications.

The packaging difference between the two parts is limited to supplier device package designation (TO-252 versus TO-252-3), which reflects internal supplier classification and does not affect physical form factor, pin configuration, or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can ZXMP6A18KTC be used as a direct replacement for ZXMP6A18KQTC?

A: Yes. The ZXMP6A18KTC is a parametric equivalent with identical electrical specifications, including Vdss (60V), continuous drain current (6.8A), on-state resistance (55mOhm), and power dissipation (2.15W). Both devices use the same TO-252-3 DPAK package and are RoHS3 compliant.

Q: Are there any differences in the physical package between these two parts?

A: Both parts use the TO-252-3 DPAK (2 Leads + Tab) surface mount package with identical pin configuration and footprint. No PCB layout modifications are required when substituting between these parts.

Q: What is the difference between the supplier device package designations TO-252 and TO-252-3?

A: The designations reflect internal supplier classification methods. Both refer to the same physical package standard (TO-252-3, DPAK, SC-63) with identical mechanical and electrical characteristics. This difference does not affect compatibility or performance.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the ZXMP6A18KQTC and ZXMP6A18KTC operate across the identical temperature range of -55°C to 150°C (TJ), enabling use in equivalent thermal environments.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both parts are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in the same manner.

Q: Which part should be selected based on availability?

A: Selection should be based on procurement requirements and lead time. The ZXMP6A18KTC has significantly higher inventory availability (9320 pieces) compared to the ZXMP6A18KQTC (1051 pieces), which may be relevant for immediate or high-volume orders.
