PDTC114YQCZ Equivalent & Substitute Parts

Part Overview

The PDTC114YQCZ is a pre-biased NPN bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. in a 3-XDFN surface mount package with wettable flank. 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 a transition frequency of 230 MHz.

The PDTC114YQCZ carries an Obsolete product status. Identification of equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production builds and field replacements.

Parameter Comparison

Engineering Selection Recommendations

The PDTC114YQC-QZ is the direct substitute for the obsolete PDTC114YQCZ. All electrical parameters, internal resistor values, and mechanical package specifications are identical. Both components are manufactured by Nexperia USA Inc. and comply with ROHS3 standards.

The primary distinction between the main part and substitute is product status: the PDTC114YQCZ is classified as Obsolete, while the PDTC114YQC-QZ maintains Active status with current manufacturing support. The substitute part additionally carries AEC-Q101 automotive qualification, indicating compliance with automotive-grade reliability and testing standards.

For new designs and production builds, the PDTC114YQC-QZ is the appropriate selection due to its active product status and assured supply chain availability. For field replacements of existing PDTC114YQCZ assemblies, the PDTC114YQC-QZ provides functional and physical equivalence with enhanced qualification credentials.

Frequently Asked Questions (FAQ)

Q: Can the PDTC114YQC-QZ be used as a direct replacement for the PDTC114YQCZ in existing designs?

A: Yes. The PDTC114YQC-QZ is electrically and mechanically equivalent to the PDTC114YQCZ. All electrical parameters, internal resistor networks, and package specifications are identical. No circuit modifications or PCB layout changes are required.

Q: What is the significance of the AEC-Q101 qualification on the PDTC114YQC-QZ?

A: AEC-Q101 is an automotive-grade qualification standard that certifies the component meets enhanced reliability, testing, and quality requirements for automotive applications. The PDTC114YQCZ does not carry this designation. If automotive-grade components are required by design specification, the PDTC114YQC-QZ satisfies this requirement.

Q: Are there any differences in package or mounting between these parts?

A: No. Both parts use the identical 3-XDFN Exposed Pad package (DFN1412D-3) with surface mount, wettable flank construction. PCB footprints, solder pad layouts, and reflow profiles are identical.

Q: Why is the PDTC114YQCZ marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production of this specific part number. The PDTC114YQC-QZ represents the active production equivalent and is the recommended part for all new applications.

Q: Are the internal bias resistor values identical between these parts?

A: Yes. Both the PDTC114YQCZ and PDTC114YQC-QZ contain identical internal base resistor (R1) of 10 kOhms and emitter-base resistor (R2) of 47 kOhms. Biasing behavior and switching characteristics are equivalent.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or humidity control requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the PDTC114YQCZ and PDTC114YQC-QZ are ROHS3 compliant, confirming the absence of restricted substances including lead, cadmium, and hexavalent chromium.
