DTA115EEBTL Equivalent & Substitute Parts Reference

Part Overview

The DTA115EEBTL from Rohm Semiconductor is a pre-biased PNP bipolar junction transistor (BJT) rated for 50V, 20mA, and 150mW maximum power dissipation in a surface-mount EMT3 (SC-75, SOT-416) package. This component includes built-in resistor networks (R1: 100 kΩ, R2: 100 kΩ), suitable for inverter, interface, and switching functions. As product lifecycle changes or differences in regional supply occur, evaluating alternative models with matching electrical and mechanical parameters ensures uninterrupted design and production.

Key Parameters

Substitute Part Grouping Explanation

Substitution is permitted strictly when key electrical and mechanical parameters match the primary requirements for the application. Only parts classified as PNP, pre-biased BJTs with a voltage rating of 50 V, the same resistor network (R1 and R2 = 100 kΩ), equivalent or higher maximum collector current, and compatible surface-mount SC-75/SOT-416 package types are included. Additional selection parameters include minimum DC current gain, maximum power dissipation, cutoff current, transition frequency, and compliance status (RoHS, REACH, MSL).

Key parameters for substitution:

• Transistor Type
• Voltage - Collector Emitter Breakdown (Max)
• Current - Collector (Ic) (Max)
• Resistor - Base (R1)
• Resistor - Emitter Base (R2)
• Mounting Type
• Package / Case
• Power - Max
• Compliance: RoHS, REACH, MSL
• Product Status

Parameter Comparison

Engineering Selection Recommendations

Both DTA115EEBTL and DTA115EET1G are active products with ROHS3 compliance, REACH unaffected status, and a Moisture Sensitivity Level of 1 (Unlimited). Each is available in a surface-mount SC-75, SOT-416 package and meets the same basic electrical and resistor network parameters. For product selection based on compliance or lifecycle status, either model maintains equivalent conformance to environmental directives and inventory logistics.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting DTA115EEBTL in a circuit?
A1: The main criteria are matching transistor type (PNP - Pre-Biased), voltage - collector-emitter breakdown (50V), resistor values (R1 and R2 = 100 kOhms), mounting type, and package compatibility (SC-75, SOT-416).

Q2: Are DTA115EEBTL and DTA115EET1G mechanically interchangeable?
A2: Both are surface-mount devices in compatible SC-75, SOT-416 outlines.

Q3: Are there differences in environmental compliance?
A3: Both devices are ROHS3 compliant, REACH unaffected, and classified with MSL: 1 (Unlimited).

Q4: Does the higher maximum collector current on DTA115EET1G affect substitution?
A4: DTA115EET1G supports a higher collector current (100 mA) while retaining all other key electrical parameters, which meets the baseline requirements for substitutability.

Q5: Are the built-in resistor values identical in both models?
A5: Yes. R1 and R2 are 100 kOhms in both.

Q6: Should designers verify product status before use?
A6: Both models are marked as "Active" in the provided data.

Q7: Is there any difference in packaging or marking that affects automated assembly?
A7: Both use tape and reel packaging and the same case style, providing parity for surface-mount assembly processes.
