PDTC143XQBZ Equivalent & Substitute Parts (Transistors, Bipolar BJT, Nexperia USA Inc.)

Part Overview

The PDTC143XQBZ is an NPN pre-biased bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. in the Transistors, Bipolar (BJT) category. It features a maximum collector current of 100 mA, collector-emitter voltage of 50 V, and is housed in a 3-XDFN Exposed Pad, DFN1110D-3 wettable flank package for surface mount assembly. This product is now classified as obsolete. Due to its discontinued status, identification of alternative models with matching electrical, mechanical, and compliance parameters is required for continuity in engineering applications and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on matching the following allowed parameters: transistor type, maximum collector current, maximum collector-emitter breakdown voltage, integrated resistor values (R1, R2), minimum DC current gain at specified operating conditions, maximum Vce saturation at provided test points, maximum collector cutoff current, transition frequency, maximum power dissipation, surface mount with wettable flank mounting, package/case code (3-XDFN Exposed Pad, DFN1110D-3), RoHS3 compliance, REACH status, and Moisture Sensitivity Level. Substitution is confined to parts with these parameters equal to or exceeding the original part where relevant and identical package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts should prioritize product status (active over obsolete) to ensure supply continuity. Both PDTC143XQBZ and PDTC143XQB-QZ are ROHS3 compliant and REACH unaffected, aligning with environmental and regulatory requirements. Consideration of Moisture Sensitivity Level is necessary, with the substitute offering a lower MSL rating (1, unlimited floor life), compared to MSL 3 (168 hours) for the original component.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for finding equivalent or substitute NPN pre-biased BJTs?
A: The critical parameters are transistor type, collector current rating, collector-emitter breakdown voltage, resistor values R1 and R2, current gain, Vce saturation voltage, cutoff current, transition frequency, power dissipation, package type, RoHS and REACH compliance, and moisture sensitivity level.

Q2: Can PDTC143XQB-QZ be used directly in place of PDTC143XQBZ?
A: PDTC143XQB-QZ matches all key electrical and mechanical parameters of PDTC143XQBZ, shares the same package (DFN1110D-3, 3-XDFN Exposed Pad), and meets the same or stricter environmental standards.

Q3: Are there differences in soldering or handling requirements between PDTC143XQBZ and PDTC143XQB-QZ?
A: The main difference is the Moisture Sensitivity Level; PDTC143XQB-QZ has MSL 1 (unlimited floor life), while PDTC143XQBZ has MSL 3 (168 hours). Both share the same mounting type and package.

Q4: Do frequency and power parameters affect interchangeability here?
A: Both devices meet or exceed base requirements for frequency (transition frequency) and power dissipation as specified for their product category and input data.

Q5: Are both parts compliant with RoHS3 and REACH?
A: Yes, each part is listed as ROHS3 compliant and REACH unaffected.
