DTA114EUBTL Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor DTA114EUBTL is an active PNP pre-biased bipolar junction transistor (BJT) rated for 50 V, 50 mA, and 200 mW in a surface mount UMT3F package. This transistor integrates base and emitter resistors, facilitating biasing for digital and analog switching applications. Identifying substitute models is necessary to ensure sourcing flexibility, maintain supply continuity, and support design interchangeability within the Transistors, Bipolar (BJT) category when inventory levels or lead times change.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts are grouped by matching essential electrical and mechanical parameters for the Transistors, Bipolar (BJT) category. Substitution is determined based on transistor type, pre-bias configuration, maximum collector-emitter voltage, resistor values R1 and R2, maximum collector current, DC current gain, saturation voltage, frequency transition, power dissipation, mounting type, compliance status, moisture sensitivity, and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both DTA114EUBTL and PDTA114EU,115 are listed as active and ROHS3 compliant, with REACH unaffected status and unlimited moisture sensitivity level (MSL 1). These factors support direct substitution in applications where supply continuity and compliance are a requirement. Both devices are categorized as PNP pre-biased BJTs for surface mount use, satisfying the mandatory product certification parameters.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters must match when choosing a substitute for DTA114EUBTL in the Transistors, Bipolar (BJT) category?
Key required parameters include transistor type (PNP - Pre-Biased), maximum collector-emitter breakdown voltage (50 V), collector current capability, base and emitter resistor values (10 kOhms each), DC current gain, saturation voltage, transition frequency, and maximum power dissipation.

Q2: Can PDTA114EU,115 be used as a direct substitute for DTA114EUBTL?
PDTA114EU,115 matches all electrical and compliance parameters with DTA114EUBTL, and is an active part with identical resistor values, voltage rating, and surface mount compatibility. Package codes differ (UMT3F vs SOT-323/SC-70), so mechanical footprint must be confirmed for layout compatibility.

Q3: What are the considerations regarding packaging when substituting these transistors?
The main part DTA114EUBTL is provided in a SC-85/UMT3F package. The substitute, PDTA114EU,115, uses SC-70/SOT-323. Both are surface mount, but differences in package dimensions and pin layout require verification against the specific PCB design to ensure proper fit.

Q4: Are both parts compliant with RoHS and REACH requirements?
Both DTA114EUBTL and PDTA114EU,115 are specified as ROHS3 compliant and REACH unaffected, supporting use in regulated and global markets.

Q5: How do moisture sensitivity levels affect substitution?
Each part is rated as MSL 1 (unlimited), indicating no restrictions on handling or storage concerning moisture, and supports standard manufacturing processes without additional precautions.
