PDTA144EQBZ Equivalent & Substitute Parts

Part Overview

The PDTA144EQBZ is a pre-biased PNP bipolar junction transistor (BJT) manufactured by Nexperia USA Inc., designed for surface mount applications in the 3-XDFN package with exposed pad. This component integrates internal base resistors (R1 and R2 at 47 kOhms each) to simplify circuit design and reduce component count in switching and amplification applications.

The PDTA144EQBZ carries an Obsolete product status. Identification of equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDTA144EQBZ is determined by electrical and mechanical parameter equivalence across the following critical criteria:

Electrical Parameters:

• Transistor type classification (PNP - Pre-Biased)
• Maximum collector current (100 mA)
• Collector-emitter breakdown voltage (50 V)
• Internal base resistor values (R1 and R2 at 47 kOhms)
• DC current gain specification (80 @ 5mA, 5V minimum)
• Saturation voltage characteristics (100mV @ 500µA, 10mA)
• Collector cutoff current (100 nA maximum)
• Transition frequency (180 MHz)
• Maximum power dissipation (340 mW)

Mechanical Parameters:

• Package type (3-XDFN Exposed Pad)
• Mounting technology (Surface Mount, Wettable Flank)
• Supplier device package designation (DFN1110D-3)

Compliance Parameters:

• RoHS3 compliance requirement
• REACH unaffected status
• ECCN classification (EAR99)

Parts meeting all electrical, mechanical, and compliance criteria are classified as direct substitutes. Variations in product status, moisture sensitivity level, or automotive qualification do not affect functional substitutability when all specified parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The PDTA144EQB-QZ is a direct functional substitute for the PDTA144EQBZ. All electrical performance parameters, mechanical package specifications, and core compliance requirements are identical between the two parts.

Key Considerations:

The PDTA144EQB-QZ carries an Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete status of the PDTA144EQBZ. This substitution addresses supply risk associated with obsolete component sourcing.

The PDTA144EQB-QZ includes Automotive grade qualification with AEC-Q101 certification, providing enhanced reliability documentation. This qualification is a superset of standard industrial requirements and does not restrict use in non-automotive applications.

The PDTA144EQB-QZ features Moisture Sensitivity Level 1 (Unlimited), compared to MSL 3 (168 Hours) for the PDTA144EQBZ. This represents an improvement in handling flexibility and storage requirements, with no negative impact on component performance or reliability.

Both parts are manufactured by Nexperia USA Inc. and share identical base product number PDTA144, confirming design lineage and parameter consistency.

Frequently Asked Questions (FAQ)

Q: Can the PDTA144EQB-QZ be used as a direct replacement for the PDTA144EQBZ in existing designs?

A: Yes. All electrical parameters, internal resistor values, package type, and mounting specifications are identical. No circuit modifications or design changes are required for substitution.

Q: What is the significance of the different product status (Obsolete vs. Active)?

A: Product status indicates lifecycle phase. The PDTA144EQBZ (Obsolete) is no longer manufactured and has limited availability. The PDTA144EQB-QZ (Active) is currently in production, ensuring reliable supply for new orders and ongoing production requirements.

Q: Does the Automotive grade qualification of the PDTA144EQB-QZ restrict its use in non-automotive applications?

A: No. Automotive qualification represents additional testing and documentation requirements. Parts qualified to automotive standards are suitable for all industrial and commercial applications.

Q: What is the practical difference between MSL 3 and MSL 1?

A: Moisture Sensitivity Level 3 requires storage at controlled humidity for a maximum of 168 hours before reflow soldering. MSL 1 (Unlimited) has no time-based storage restrictions. The PDTA144EQB-QZ offers greater handling flexibility and reduced risk of moisture-related defects during storage and assembly.

Q: Are the internal base resistor values identical in both parts?

A: Yes. Both the PDTA144EQBZ and PDTA144EQB-QZ contain R1 and R2 base resistors at 47 kOhms each. This ensures identical biasing characteristics and circuit behavior.

Q: Is the 3-XDFN package footprint identical between both parts?

A: Yes. Both parts use the 3-XDFN Exposed Pad package with DFN1110D-3 supplier designation. PCB layouts, solder paste stencils, and pick-and-place programming require no modification.

Q: Are there any compliance or regulatory differences between the two parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. No compliance differences exist that would affect design or supply chain requirements.
