ZXTDAM832TA Equivalent & Substitute Parts

Part Overview

The ZXTDAM832TA is a Bipolar (BJT) Transistor Array featuring a dual 2 NPN configuration manufactured by Diodes Incorporated. This component is rated for 15V collector-emitter breakdown voltage with a maximum collector current of 4.5A and operates across a temperature range of -55°C to 150°C. The device is packaged in an 8-MLP (3x2) surface mount configuration with 1.7W maximum power dissipation.

The ZXTDAM832TA has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this dual NPN transistor array.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZXTDAM832TA is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor configuration: Dual 2 NPN topology
• Voltage rating: Minimum 15V collector-emitter breakdown voltage
• Current capability: Minimum 4.5A maximum collector current
• Power dissipation: Minimum 1.7W maximum power rating
• Operating temperature range: -55°C to 150°C (TJ)

Mechanical Compatibility Criteria:

• Mounting type: Surface mount only
• Package class: 8-pin DFN/MLP variants with exposed pad

Compliance Requirements:

• RoHS3 compliance mandatory
• MSL rating of 1 (Unlimited) required

The ZXTD617MCTA meets all substitution criteria as a direct equivalent. This part maintains the dual NPN configuration, meets or exceeds all electrical ratings, operates within the required temperature range, and maintains full RoHS3 and MSL compliance. The substitute part is currently in active production status, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The ZXTD617MCTA is a direct functional equivalent to the obsolete ZXTDAM832TA. Both components are manufactured by Diodes Incorporated and maintain identical compliance certifications (ROHS3 Compliant, MSL 1 Unlimited, REACH Unaffected, EAR99 ECCN classification).

Substitution Advantages:

The ZXTD617MCTA offers enhanced electrical performance characteristics. The maximum collector current rating increases from 4.5A to 5.0A, providing additional current headroom. The part is currently in active production status with substantial inventory availability (30,200 pieces), ensuring reliable long-term supply compared to the obsolete ZXTDAM832TA (1,576 pieces remaining).

Electrical Considerations:

The substitute part maintains the 15V collector-emitter breakdown voltage and 1.7W maximum power dissipation. The transition frequency decreases from 120MHz to 80MHz; this parameter change is acceptable for applications not requiring the higher frequency performance of the original part. The DC current gain (hFE) specification improves from 200 (minimum) to 300 (minimum), indicating enhanced amplification characteristics.

Package Compatibility:

Both components utilize 8-pin surface mount DFN packages with exposed pads. The ZXTDAM832TA uses 8-VDFN packaging while the ZXTD617MCTA uses 8-WDFN3020-8 packaging. These packages maintain compatible pinouts and footprints suitable for direct PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can the ZXTD617MCTA directly replace the ZXTDAM832TA on existing PCBs?

A: Yes. Both components feature 8-pin surface mount DFN packages with exposed pads and compatible pinouts. The footprint dimensions support direct substitution without PCB redesign.

Q: What are the key electrical differences between these parts?

A: The ZXTD617MCTA provides higher maximum collector current (5.0A versus 4.5A) and improved DC current gain (300 minimum versus 200 minimum). The transition frequency is lower (80MHz versus 120MHz). All voltage ratings and power dissipation limits remain identical.

Q: Is the lower transition frequency of the ZXTD617MCTA a limitation?

A: The transition frequency reduction from 120MHz to 80MHz affects high-frequency switching applications. For applications operating below 80MHz, this parameter change is not a functional limitation. Applications requiring frequencies above 80MHz require evaluation against specific circuit requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ZXTDAM832TA and ZXTD617MCTA are ROHS3 Compliant with MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing and environmental standards.

Q: What is the inventory status difference?

A: The ZXTDAM832TA (obsolete) has 1,576 pieces remaining in stock. The ZXTD617MCTA (active production) has 30,200 pieces available, providing significantly greater supply security for new designs and ongoing production.

Q: Are there any package marking or labeling differences?

A: The ZXTDAM832TA uses 8-VDFN packaging while the ZXTD617MCTA uses 8-WDFN3020-8 packaging. Component markings and labeling differ accordingly, but functional pinout and electrical characteristics remain compatible.

Q: Can the ZXTD617MCTA be used in new designs?

A: Yes. The ZXTD617MCTA is in active production status and is suitable for new designs. The part meets all compliance requirements and offers improved electrical performance characteristics compared to the obsolete ZXTDAM832TA.
