PDTC144ETVL Equivalent & Substitute Parts

Part Overview

The PDTC144ETVL is an active pre-biased NPN bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. in Surface Mount TO-236AB packaging. This component integrates internal base and emitter-base resistors, enabling direct logic-level switching applications without external biasing networks. The device is rated for 50 V collector-emitter breakdown voltage and 100 mA maximum collector current with 250 mW power dissipation. Substitute parts are identified based on matching electrical specifications, package compatibility, and regulatory compliance to support design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDTC144ETVL is determined by equivalence across the following critical parameters:

Electrical Specifications:

• Maximum collector current: 100 mA
• Collector-emitter breakdown voltage: 50 V
• Internal base resistor (R1): 47 kOhms
• Internal emitter-base resistor (R2): 47 kOhms
• Minimum DC current gain (hFE): 80
• Maximum power dissipation: 250 mW or greater

Package Compatibility:

• Surface Mount TO-236-3 / SOT-23-3 footprint
• Three-terminal configuration

Regulatory & Compliance:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• Active product status

The MMUN2213LT1G from onsemi meets all specified electrical parameters and package requirements, with equivalent internal resistor values and collector current ratings. Both devices operate within the same voltage and power envelope and share identical package footprints.

Parameter Comparison

Engineering Selection Recommendations

Both the PDTC144ETVL and MMUN2213LT1G are active products with full RoHS3 compliance and MSL Level 1 moisture sensitivity ratings. Selection between these devices is based on availability, supply chain requirements, and packaging format preference.

The PDTC144ETVL is supplied in Tape & Reel (TR) format by Nexperia USA Inc. with 1483 pieces in current inventory.

The MMUN2213LT1G is supplied in Cut Tape (CT) and Digi-Reel® format by onsemi with 104100 pieces in current inventory.

Both devices are electrically equivalent within the specified parameter tolerances and share identical TO-236-3 / SOT-23-3 surface mount footprints. The marginal difference in maximum power rating (250 mW versus 246 mW) and saturation voltage characteristics do not affect functional equivalence for standard pre-biased switching applications.

Frequently Asked Questions (FAQ)

Q: Are the PDTC144ETVL and MMUN2213LT1G pin-compatible?

A: Yes. Both devices use the TO-236-3 / SOT-23-3 three-terminal surface mount package with identical pin assignments for collector, base, and emitter terminals.

Q: Can the MMUN2213LT1G replace the PDTC144ETVL in existing designs?

A: Yes. The MMUN2213LT1G meets all electrical specifications of the PDTC144ETVL, including collector current, breakdown voltage, internal resistor values, and current gain. No circuit modifications are required.

Q: What is the difference in packaging between these two parts?

A: The PDTC144ETVL is supplied in Tape & Reel (TR) format. The MMUN2213LT1G is supplied in Cut Tape (CT) and Digi-Reel® format. Both use identical TO-236-3 / SOT-23-3 surface mount packages suitable for automated assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both the PDTC144ETVL and MMUN2213LT1G are ROHS3 compliant with MSL Level 1 moisture sensitivity ratings.

Q: What are the key electrical parameters that determine substitution?

A: Substitution is determined by matching maximum collector current (100 mA), collector-emitter breakdown voltage (50 V), internal base and emitter-base resistor values (47 kOhms each), minimum DC current gain (80), and maximum power dissipation (250 mW or greater).

Q: Can these parts be used interchangeably in high-frequency applications?

A: Substitution is based on the DC electrical parameters provided. Frequency-dependent characteristics are not included in the specified parameter set and must be evaluated separately against application requirements.
