Part Overview

The DTA114TE-TP is a pre-biased PNP bipolar junction transistor (BJT) manufactured by Micro Commercial Co, designed for surface mount applications in the SOT-523 package. This component operates at 50 V maximum collector-emitter breakdown voltage with a maximum collector current of 100 mA and transition frequency of 250 MHz. The device is actively produced and RoHS3 compliant, making it suitable for modern electronic applications requiring compact switching and amplification functions.

Equivalent and substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility across manufacturing sources is required. The parts listed below maintain electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DTA114TE-TP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Transistor type: PNP - Pre-Biased configuration
• Maximum collector current: 100 mA
• Maximum collector-emitter breakdown voltage: 50 V
• Base resistor value: 10 kOhms (primary criterion for pre-biased configuration)
• DC current gain minimum: 100 @ 1mA, 5V
• Transition frequency: 250 MHz
• Maximum power dissipation: 150 mW or greater

Mechanical Equivalence Criteria:

• Surface mount package: SOT-523 or functionally equivalent package
• Mounting type: Surface mount
• Compliance: RoHS3 compliant, REACH unaffected

Direct Substitutes maintain all electrical parameters and use the SOT-523 package with identical base resistor value (10 kOhms).

Compatible Alternatives maintain core electrical specifications but may use different package designations (SC-75, SOT-416, EMT3) or have different base resistor values (4.7 kOhms), requiring circuit design verification for base bias network compatibility.

Engineering Selection Recommendations

Direct Substitutes (Recommended for Pin-Compatible Replacement):

The DDTA114TE-7-F (Diodes Incorporated) is the primary direct substitute for the DTA114TE-TP. Both devices share identical electrical specifications, SOT-523 package configuration, and 10 kOhms base resistor value. The DDTA114TE-7-F maintains active product status with significantly higher inventory availability (53,180 units in stock versus 1,144 units for the DTA114TE-TP). This part is suitable for direct board-level substitution without circuit modification.

Compatible Alternatives (Package Consideration Required):

The DTA114TETL (Rohm Semiconductor) provides electrical equivalence with identical base resistor value (10 kOhms) and matching electrical parameters. However, this part uses the EMT3 package designation (SC-75, SOT-416) rather than SOT-523. PCB layout and footprint compatibility must be verified before selection. The DTA114TETL is actively produced with 17,179 units in stock.

The DTA143TETL (Rohm Semiconductor) differs in base resistor value (4.7 kOhms versus 10 kOhms), resulting in different pre-bias characteristics. This part is suitable only when the lower base resistance value is compatible with the target application circuit. The DTA143TETL is actively produced with 32,400 units in stock.

Not Recommended:

The DTA114TET1G (onsemi) carries obsolete product status and uses a different package (SC-75, SOT-416). While electrical parameters are generally compatible, the obsolete designation indicates discontinued manufacturing and limited future availability. This part should not be selected for new designs or long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can the DDTA114TE-7-F replace the DTA114TE-TP without any circuit modifications?

A: Yes. The DDTA114TE-7-F is a direct electrical and mechanical equivalent. Both devices use the SOT-523 package, share identical base resistor values (10 kOhms), and meet the same electrical specifications. No circuit modifications are required for substitution.

Q: What is the significance of the base resistor value in pre-biased transistors?

A: The base resistor value (R1) determines the pre-bias current and switching characteristics of the transistor. The DTA114TE-TP and its direct substitutes use 10 kOhms. The DTA143TETL uses 4.7 kOhms, which produces different bias conditions. Substitution between different base resistor values requires verification that the application circuit can accommodate the altered bias network behavior.

Q: Why is the DTA114TET1G listed as obsolete?

A: The DTA114TET1G carries an obsolete product status designation from onsemi, indicating that the manufacturer has discontinued active production. While existing inventory may be available, this part should not be selected for new designs or applications requiring long-term component availability.

Q: Are there package compatibility issues between SOT-523 and SC-75/SOT-416?

A: Yes. SOT-523 and SC-75 (SOT-416) are different package formats with different pin configurations and PCB footprints. The DTA114TETL and DTA143TETL use SC-75/SOT-416 packages, while the DTA114TE-TP uses SOT-523. Direct board-level substitution between these packages is not possible without PCB redesign. Verify footprint compatibility before selecting these alternatives.

Q: What compliance certifications apply to all listed substitute parts?

A: All substitute parts listed are RoHS3 compliant and REACH unaffected. All parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: How do the electrical specifications of DDTA114TE-7-F differ from DTA114TE-TP?

A: The DDTA114TE-7-F and DTA114TE-TP share identical maximum ratings and core electrical specifications. A minor difference exists in Vce saturation test conditions: DDTA114TE-7-F is specified at 100µA, 1mA while DTA114TE-TP is specified at 1mA, 10mA. Both parts meet the 300mV maximum saturation voltage requirement and are functionally equivalent for circuit applications.

Q: Can the DTA143TETL be used as a substitute if the application requires lower base bias current?

A: The DTA143TETL uses a 4.7 kOhms base resistor compared to the 10 kOhms in the DTA114TE-TP. This results in approximately double the pre-bias current. Substitution is only appropriate if the application circuit design accommodates this higher bias current. Circuit analysis is required to confirm compatibility.

Q: What inventory considerations should guide part selection?

A: The DDTA114TE-7-F offers the highest inventory availability (53,180 units) among direct substitutes, providing supply security for production requirements. The DTA114TE-TP (1,144 units) and DTA114TETL (17,179 units) have more limited availability. For applications with extended production timelines, the DDTA114TE-7-F is the preferred choice based on supply continuity.
