Substitute Part Grouping Explanation

Substitute parts for the ZUMT718TC are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Transistor Type: PNP
• Maximum Collector Current (Ic): 1 A
• Collector-Emitter Breakdown Voltage: 20 V
• Vce Saturation: 250 mV @ 100 mA, 1 A
• Collector Cutoff Current: 10 nA
• DC Current Gain (hFE): 200 @ 500 mA, 2 V
• Maximum Power Dissipation: 500 mW
• Transition Frequency: 210 MHz
• Operating Temperature Range: -55°C to 150°C

Mechanical Parameters (Must Match):

• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all electrical, mechanical, and compliance parameters are classified as direct substitutes and are electrically and functionally interchangeable with the ZUMT718TC.

Parameter Comparison

Engineering Selection Recommendations

The ZUMT718TA is a direct electrical and mechanical equivalent to the ZUMT718TC. Both devices are manufactured by Diodes Incorporated and share identical electrical specifications across all critical parameters: collector current, breakdown voltage, saturation voltage, current gain, power dissipation, and transition frequency. Both operate across the same temperature range and are packaged in the SC-70/SOT-323 form factor.

The primary distinction between these parts is product status and packaging configuration. The ZUMT718TC is classified as Obsolete, while the ZUMT718TA maintains Active product status. The ZUMT718TA is supplied in Tape & Reel (TR) packaging, whereas the ZUMT718TC is supplied in Tube packaging. Both devices are ROHS3 Compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

For new designs and ongoing production requiring PNP BJT transistors with 1 A collector current and 20 V breakdown voltage in SOT-323 packaging, the ZUMT718TA is the appropriate selection due to its Active product status and continued availability.

Frequently Asked Questions (FAQ)

Q: Can the ZUMT718TA be used as a direct replacement for the ZUMT718TC?

A: Yes. The ZUMT718TA is electrically and mechanically equivalent to the ZUMT718TC. All electrical parameters, including collector current, breakdown voltage, saturation voltage, current gain, power dissipation, and transition frequency, are identical. Both devices use the SC-70/SOT-323 package and are suitable for Surface Mount assembly.

Q: What is the difference between the ZUMT718TC and ZUMT718TA?

A: The ZUMT718TC is Obsolete, while the ZUMT718TA is Active. The ZUMT718TA is supplied in Tape & Reel (TR) packaging, whereas the ZUMT718TC is supplied in Tube packaging. Electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the ZUMT718TC and ZUMT718TA are ROHS3 Compliant, REACH Unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8541.21.0075.

Q: What is the SC-70/SOT-323 package?

A: SC-70 and SOT-323 refer to the same Surface Mount package form factor. This is a compact three-lead package commonly used for small-signal transistors and diodes. The package dimensions and lead configuration are standardized across manufacturers.

Q: Can I use the ZUMT718TA in existing designs that specify the ZUMT718TC?

A: Yes. The ZUMT718TA is a direct substitute. No circuit modifications or design changes are required. The identical electrical specifications and package form factor ensure pin-for-pin and functional compatibility.

Q: What does "Obsolete" product status mean for the ZUMT718TC?

A: Obsolete status indicates that the ZUMT718TC is no longer in active production and will not be manufactured in the future. Existing inventory may be available from distributors, but long-term supply cannot be guaranteed. The ZUMT718TA, with Active status, is the recommended alternative for continued supply assurance.

Q: Are there inventory considerations when selecting between these parts?

A: The ZUMT718TA has significantly higher inventory availability (45,100 Pcs) compared to the ZUMT718TC (918 Pcs). For applications requiring sustained production volumes, the ZUMT718TA is the preferred choice due to superior supply chain availability.
