PDTA114EQBZ Equivalent & Substitute Parts

Part Overview

The PDTA114EQBZ is a pre-biased PNP bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. in a 3-XDFN surface mount package with wettable flank. This component integrates internal base and emitter-base resistors, enabling direct logic-level switching applications without external biasing networks. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution of the PDTA114EQBZ is determined by electrical and mechanical parameter equivalence. The following criteria establish functional interchangeability:

Electrical Parameters (Critical):

• Transistor type: PNP - Pre-Biased configuration
• Maximum collector current: 100 mA
• Collector-emitter breakdown voltage: 50 V
• Internal base resistor (R1): 10 kOhms
• Internal emitter-base resistor (R2): 10 kOhms
• DC current gain (hFE): 30 minimum at specified conditions
• Saturation voltage: 100 mV maximum at specified conditions
• Transition frequency: 180 MHz
• Maximum power dissipation: 340 mW

Mechanical Parameters (Critical):

• Package type: 3-XDFN Exposed Pad (DFN1110D-3)
• Mounting: Surface Mount with Wettable Flank
• Lead-free and RoHS3 compliant

Substitute parts must match all electrical specifications and package configuration to ensure direct replacement without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The PDTA114EQB-QZ is the direct functional equivalent of the PDTA114EQBZ. All electrical parameters, internal resistor values, and package specifications are identical. The substitute part is manufactured by the same supplier (Nexperia USA Inc.) and maintains full compatibility with existing circuit designs and PCB layouts.

Key Advantages of PDTA114EQB-QZ:

• Active product status ensures long-term availability and supply chain continuity
• AEC-Q101 automotive qualification provides enhanced reliability documentation
• Improved moisture sensitivity level (MSL 1 vs. MSL 3) reduces handling and storage constraints
• Identical electrical performance eliminates circuit redesign requirements
• Same package and mounting configuration permits direct PCB substitution

The PDTA114EQB-QZ is suitable for all applications previously served by the PDTA114EQBZ without modification to schematic design, PCB layout, or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PDTA114EQB-QZ replace PDTA114EQBZ in existing designs?

A: Yes. The PDTA114EQB-QZ is electrically and mechanically identical to the PDTA114EQBZ. All electrical parameters, internal resistor values, and package specifications match exactly. Direct substitution is possible without circuit or layout changes.

Q: What is the difference between PDTA114EQBZ and PDTA114EQB-QZ?

A: The primary differences are product status and qualification level. PDTA114EQBZ is obsolete; PDTA114EQB-QZ is active. PDTA114EQB-QZ includes AEC-Q101 automotive qualification and has improved moisture sensitivity (MSL 1 vs. MSL 3). Electrical performance and package are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 3-XDFN Exposed Pad package (DFN1110D-3) with wettable flank. Pinout, pad layout, and mounting requirements are identical.

Q: Does the improved MSL rating affect circuit performance?

A: No. Moisture sensitivity level (MSL) affects component handling, storage, and assembly conditions, not electrical performance. MSL 1 (unlimited shelf life) is superior to MSL 3 (168-hour limit) and reduces storage and logistics constraints.

Q: Is AEC-Q101 qualification required for my application?

A: AEC-Q101 is an automotive industry reliability standard. If your application requires automotive-grade components, PDTA114EQB-QZ meets this requirement. PDTA114EQBZ does not carry this qualification.

Q: Can I use these parts interchangeably in production?

A: Yes. Both parts are manufactured by Nexperia USA Inc. and are electrically and mechanically equivalent. They can be used interchangeably in production without design changes or process modifications.

Q: What is the base product number?

A: The base product number for both parts is PDTA114. The suffixes (-EQBZ and -EQB-QZ) indicate packaging and qualification variants.
