PDTA114TMB,315 Equivalent & Substitute Parts

Part Overview

The PDTA114TMB,315 is a pre-biased PNP bipolar junction transistor manufactured by Nexperia USA Inc., designed for surface mount applications in the 3-XFDFN package. This component operates at 50 V collector-emitter breakdown voltage with a maximum collector current of 100 mA and is qualified to AEC-Q100 automotive standards. The part is currently in active production status with 1023 units in stock.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical and mechanical parameters of alternative manufacturers' offerings. The substitute parts listed maintain compatibility through equivalent electrical specifications and surface mount packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PDTA114TMB,315 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Transistor type must be PNP - Pre-Biased
• Voltage - Collector Emitter Breakdown (Max) must be 50 V or greater
• Current - Collector (Ic) (Max) must be 100 mA or greater
• Resistor - Base (R1) must be 10 kOhms
• Power dissipation capability must be 250 mW or greater

Mechanical Compatibility Requirements:

• Mounting type must be Surface Mount
• Package must accommodate DFN or equivalent surface mount footprints

Compliance Requirements:

• RoHS3 compliance required
• Moisture Sensitivity Level (MSL) must be 1 (Unlimited)

The substitute parts NSBA114TF3T5G and RN2111ACT(TPL3) meet these core substitution criteria, though with variations in secondary parameters such as DC current gain, saturation voltage, and transition frequency that do not affect functional interchangeability within the specified electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

NSBA114TF3T5G (onsemi): This substitute operates within the electrical envelope of the PDTA114TMB,315 with equivalent maximum collector current (100 mA) and breakdown voltage (50 V). The part carries ROHS3 compliance and unlimited moisture sensitivity rating. However, the product status is listed as Last Time Buy, indicating limited future availability. Selection of this substitute should account for long-term supply planning requirements.

RN2111ACT(TPL3) (Toshiba Semiconductor and Storage): This substitute maintains the 50 V breakdown voltage and 10 kOhm base resistor specification. The maximum collector current is rated at 80 mA, which is lower than the primary part's 100 mA specification. The maximum power dissipation is 100 mW, significantly lower than the primary part's 250 mW rating. This part is suitable for applications where collector current requirements do not exceed 80 mA and power dissipation remains below 100 mW. The product maintains active status with high inventory availability (10678 units in stock). RoHS compliance is confirmed, and MSL rating is 1 (Unlimited).

Both substitute parts are surface mount devices with RoHS compliance and unlimited moisture sensitivity, supporting direct substitution in compliant manufacturing environments. Package differences (SOT-1123 and CST3 versus 3-XFDFN) require PCB layout verification prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can NSBA114TF3T5G be used as a direct replacement for PDTA114TMB,315?

A: NSBA114TF3T5G meets the core electrical specifications: 50 V breakdown voltage, 100 mA maximum collector current, and 10 kOhm base resistor. Both parts are surface mount with ROHS3 compliance and MSL 1 rating. Package differences exist (SOT-1123 versus 3-XFDFN), requiring PCB footprint verification. The primary consideration is the Last Time Buy status of the onsemi part, which limits future procurement availability.

Q: Is RN2111ACT(TPL3) suitable for all applications using PDTA114TMB,315?

A: RN2111ACT(TPL3) is suitable for applications where the maximum collector current requirement does not exceed 80 mA and power dissipation remains below 100 mW. The primary part supports 100 mA and 250 mW. Applications operating at or near these maximum ratings require the primary part or NSBA114TF3T5G. The Toshiba part maintains active product status with strong inventory availability.

Q: What are the package compatibility considerations?

A: The primary part uses 3-XFDFN packaging. NSBA114TF3T5G uses SOT-1123, and RN2111ACT(TPL3) uses CST3 (SC-101, SOT-883). These packages have different footprints and pin configurations. PCB layout and schematic verification is required before substitution to ensure mechanical and electrical compatibility with existing designs.

Q: Are all substitute parts RoHS compliant?

A: Yes. PDTA114TMB,315 and NSBA114TF3T5G are ROHS3 compliant. RN2111ACT(TPL3) is RoHS compliant. All parts meet environmental compliance requirements for restricted substance use.

Q: What is the significance of the Last Time Buy status for NSBA114TF3T5G?

A: Last Time Buy status indicates that onsemi has announced end-of-life for this component. New orders may be accepted for a limited period, but production will cease. Existing inventory may be available, but long-term supply cannot be guaranteed. For designs requiring sustained production support, RN2111ACT(TPL3) or the primary PDTA114TMB,315 are preferred.

Q: Can these parts be used interchangeably in automotive applications?

A: PDTA114TMB,315 carries AEC-Q100 automotive qualification. NSBA114TF3T5G and RN2111ACT(TPL3) do not list AEC-Q100 qualification in the provided specifications. Automotive applications requiring AEC-Q100 certification must use the primary part or verify alternative qualification status with the respective manufacturers.
