Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDTA113EM,315 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Transistor type must be PNP pre-biased configuration
• Collector-emitter breakdown voltage must be 50 V or greater
• Maximum collector current must be 100 mA or greater
• Power dissipation rating must be 250 mW or greater
• Surface mount packaging required

Mechanical Compatibility Criteria:

• Surface mount package format (SOT-883 or equivalent 3-pin DFN packages)
• Tape & Reel (TR) packaging format

Compliance Criteria:

• RoHS3 compliance required
• Moisture sensitivity level MSL 1 (Unlimited) preferred
• Active product status

The identified substitute parts meet these core requirements while maintaining functional equivalence. Variations in internal bias resistor values, DC current gain characteristics, and transition frequency do not preclude substitution when the primary electrical parameters remain within acceptable ranges for the application circuit.

Parameter Comparison

Engineering Selection Recommendations

PDTA113EM,315 (Primary Part): The PDTA113EM,315 is the specified component and remains the first choice when available. It carries AEC-Q100 automotive qualification and is Active in product status. This part is suitable for applications requiring 100 mA maximum collector current with 50 V breakdown voltage and integrated 1 kOhm base bias resistors.

DDTA114YLP-7 (Substitute - Diodes Incorporated): The DDTA114YLP-7 provides electrical equivalence with identical maximum collector current (100 mA) and collector-emitter breakdown voltage (50 V). This part features higher DC current gain (80 vs. 30 minimum) and lower collector cutoff current (500 nA vs. 1 µA). The internal bias resistor configuration differs (10 kOhm and 47 kOhm vs. 1 kOhm and 1 kOhm), which affects circuit biasing characteristics. This part is Active in product status and RoHS3 compliant. Package format is 3-UFDFN, requiring PCB layout adjustment from SOT-883. No automotive qualification is listed for this part.

DDTA144ELP-7 (Substitute - Diodes Incorporated): The DDTA144ELP-7 provides enhanced current capability with 200 mA maximum collector current, exceeding the PDTA113EM,315 specification. Collector-emitter breakdown voltage remains at 50 V. This part carries AEC-Q101 automotive qualification and is Active in product status. The internal bias resistor configuration is 47 kOhm and 47 kOhm, differing from the primary part. DC current gain is significantly higher (250 vs. 30 minimum), and Vce saturation is higher (800 mV vs. 150 mV). Package format is 3-UFDFN, requiring PCB layout adjustment from SOT-883.

Selection Basis:

• For direct electrical and mechanical replacement with automotive qualification: PDTA113EM,315 (primary)
• For equivalent 100 mA performance with different bias resistor network: DDTA114YLP-7
• For higher current capability (200 mA) with automotive qualification: DDTA144ELP-7

All substitute parts maintain RoHS3 compliance, MSL 1 moisture sensitivity, and 250 mW power dissipation ratings. Package format differences require PCB design verification.

Frequently Asked Questions (FAQ)

Q: Can DDTA114YLP-7 be used as a direct replacement for PDTA113EM,315?

A: The DDTA114YLP-7 meets the core electrical requirements (100 mA collector current, 50 V breakdown voltage, 250 mW power dissipation) and is RoHS3 compliant. However, three differences exist: (1) Package format changes from SOT-883 to 3-UFDFN, requiring PCB layout modification; (2) Internal bias resistor values differ (10 kOhm/47 kOhm vs. 1 kOhm/1 kOhm), affecting circuit biasing behavior; (3) No automotive qualification is listed for DDTA114YLP-7, whereas PDTA113EM,315 carries AEC-Q100. Substitution is feasible only when the application circuit tolerates the bias resistor differences and automotive qualification is not required.

Q: What is the difference between DDTA114YLP-7 and DDTA144ELP-7?

A: The primary differences are: (1) Maximum collector current: DDTA114YLP-7 is rated 100 mA, DDTA144ELP-7 is rated 200 mA; (2) Internal bias resistors: DDTA114YLP-7 uses 10 kOhm/47 kOhm, DDTA144ELP-7 uses 47 kOhm/47 kOhm; (3) DC current gain: DDTA114YLP-7 minimum is 80, DDTA144ELP-7 minimum is 250; (4) Vce saturation: DDTA114YLP-7 is 250 mV maximum, DDTA144ELP-7 is 800 mV maximum; (5) Automotive qualification: DDTA144ELP-7 carries AEC-Q101, DDTA114YLP-7 has no listed automotive qualification. Both share the same 50 V breakdown voltage, 250 mW power dissipation, and 3-UFDFN package format.

Q: Does package format affect substitution compatibility?

A: Yes. The PDTA113EM,315 uses SOT-883 (SC-101) packaging, while both DDTA114YLP-7 and DDTA144ELP-7 use 3-UFDFN (X1-DFN1006-3) packaging. Although both are surface mount formats, the physical dimensions, pin pitch, and PCB footprint differ. Direct board-level substitution without PCB layout modification is not possible. Design verification and potential PCB rework are required when switching between these package formats.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The PDTA113EM,315, DDTA114YLP-7, and DDTA144ELP-7 are all RoHS3 compliant. All three parts also carry MSL 1 (Unlimited) moisture sensitivity level classification and REACH Unaffected status.

Q: Which substitute part is recommended for automotive applications?

A: For automotive applications, DDTA144ELP-7 is the appropriate substitute, as it carries AEC-Q101 automotive qualification. The PDTA113EM,315 carries AEC-Q100 qualification. The DDTA114YLP-7 has no listed automotive qualification and is not suitable for automotive-grade applications.

Q: How do internal bias resistor differences affect circuit operation?

A: The PDTA113EM,315 integrates 1 kOhm base resistor (R1) and 1 kOhm emitter-base resistor (R2). The DDTA114YLP-7 uses 10 kOhm (R1) and 47 kOhm (R2), while DDTA144ELP-7 uses 47 kOhm (R1) and 47 kOhm (R2). These differences affect the bias point, switching speed, and input impedance of the transistor. Circuit simulation or testing is necessary to confirm functional equivalence in the specific application. Higher resistor values reduce base current requirements and power consumption but may affect switching characteristics.

Q: What is the maximum collector current for each part?

A: PDTA113EM,315 and DDTA114YLP-7 are both rated for 100 mA maximum collector current. DDTA144ELP-7 is rated for 200 mA maximum collector current, providing double the current capability.
