Substitute Part Grouping Explanation

Substitution of the PDTA115EE,115 is determined by strict equivalence across the following electrical and mechanical criteria:

Primary Equivalence Criteria:

Transistor polarity and pre-biased configuration (PNP)
Collector-emitter breakdown voltage (50 V minimum)
Base and emitter-base resistor values (100 kOhms each)
Maximum collector current rating (20 mA minimum)
Power dissipation capability (150 mW minimum)
Surface mount package compatibility (SC-75 / SOT-416 footprint)
RoHS3 compliance and MSL 1 rating

Direct Equivalents: Parts that maintain identical or superior electrical specifications with matching internal resistor values and collector current ratings qualify as direct substitutes. These include DTA115EET1G (onsemi) and DTA115EETL (Rohm Semiconductor), both active products with 100 kOhms base resistors and 20 mA collector current ratings.

Functional Alternatives: Parts with different internal resistor values or higher collector current ratings (DTA123EETL, DTA124EETL, DTA143EETL, DTA144EETL) function as substitutes when circuit design accommodates the modified biasing network. These alternatives maintain 50 V breakdown voltage and surface mount SC-75 packaging but introduce different switching characteristics through altered resistor networks.

Package Variants: PDTA115EM,315 (SOT-883) and PDTA115EMB,315 (DFN1006B-3) provide electrical equivalence with alternative surface mount packages, suitable only when PCB layout permits package substitution.

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Specifications):

DTA115EETL (Rohm Semiconductor) provides the closest functional equivalent to PDTA115EE,115. Both components feature 20 mA maximum collector current, 100 kOhms base and emitter-base resistors, and 50 V breakdown voltage. DTA115EETL is active product status with ROHS3 compliance and MSL 1 rating. The SC-75 package footprint is identical, enabling direct PCB substitution. Vce saturation specification differs (300 mV versus 150 mV), reflecting manufacturing process variations between Rohm and NXP but maintaining functional compatibility within typical circuit tolerances.

Higher Current Capability Alternative:

DTA115EET1G (onsemi) extends collector current rating to 100 mA while maintaining 100 kOhms resistor values and 50 V breakdown voltage. This part is suitable for applications requiring increased current headroom. Active product status, ROHS3 compliance, and SC-75 packaging confirm compatibility. Selection of this part is appropriate when circuit design permits higher current operation without modification.

Modified Biasing Network Alternatives:

DTA114EETL, DTA123EETL, DTA124EETL, DTA143EETL, and DTA144EETL offer 50 V breakdown voltage and SC-75 packaging with altered internal resistor networks. These parts require circuit evaluation to confirm biasing point compatibility. All are active products with ROHS3 compliance and MSL 1 rating. Selection depends on specific application requirements for switching speed, current gain, and biasing characteristics.

Package Variant Options:

PDTA115EM,315 (SOT-883) and PDTA115EMB,315 (DFN1006B-3) maintain identical electrical specifications to PDTA115EE,115 with alternative surface mount packages. These options are suitable only when PCB layout and assembly equipment support the alternative package geometry. Both are active products with full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can DTA115EET1G replace PDTA115EE,115 in all applications?

A: DTA115EET1G maintains identical base and emitter-base resistor values (100 kOhms each) and 50 V breakdown voltage, enabling direct substitution in most applications. The higher collector current rating (100 mA versus 20 mA) provides additional design margin. Vce saturation specification differs (250 mV versus 150 mV), which may affect switching speed in time-critical circuits. Circuit validation is recommended for applications with strict saturation voltage requirements.

Q: What is the difference between DTA115EETL and DTA115EET1G?

A: Both parts feature identical electrical specifications (20 mA or 100 mA collector current, 100 kOhms resistors, 50 V breakdown). DTA115EETL is manufactured by Rohm Semiconductor in EMT3 package variant with Cut Tape & Digi-Reel packaging. DTA115EET1G is manufactured by onsemi in SC-75 package with Tape & Reel packaging. Selection depends on supplier availability, packaging preference, and procurement requirements.

Q: Can I use DTA123EETL as a substitute for PDTA115EE,115?

A: DTA123EETL maintains 50 V breakdown voltage and SC-75 packaging but features 2.2 kOhms base and emitter-base resistors (versus 100 kOhms in PDTA115EE,115). This significantly alters the biasing network and switching characteristics. Substitution requires circuit redesign to accommodate the modified resistor values. Use only when application requirements permit biasing point adjustment.

Q: Are PDTA115EM,315 and PDTA115EMB,315 electrically identical to PDTA115EE,115?

A: Yes, both parts maintain identical electrical specifications including 20 mA collector current, 100 kOhms resistors, and 50 V breakdown voltage. PDTA115EM,315 uses SOT-883 package; PDTA115EMB,315 uses DFN1006B-3 package. Substitution is limited to applications where PCB layout and assembly equipment support the alternative package footprint.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. REACH status is unaffected for all components. ECCN classification is EAR99 for all parts. These certifications confirm suitability for commercial and industrial applications with standard handling and storage requirements.

Q: How do I determine which substitute part is appropriate for my application?

A: Evaluate three primary criteria: (1) Collector current requirement—if application requires ≤20 mA, DTA115EETL or PDTA115EM,315 are preferred; if higher current is acceptable, DTA115EET1G is suitable. (2) Biasing network—if 100 kOhms resistors are required, use DTA115EETL, DTA115EET1G, or package variants; if modified biasing is acceptable, evaluate DTA114EETL through DTA144EETL. (3) Package footprint—confirm PCB layout compatibility with SC-75, SOT-883, or DFN1006B-3 packages.

Q: Is product status (Active vs. Obsolete) a factor in substitution selection?

A: Yes. PDTA115EE,115 is obsolete, necessitating substitution with active products to ensure long-term supply availability and manufacturing continuity. All recommended substitutes are active products with confirmed inventory levels and ongoing production. Selection of active products eliminates future obsolescence risk and supports extended product lifecycle requirements.
