DTC123JUBTL Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor DTC123JUBTL is a pre-biased NPN bipolar junction transistor (BJT) designed for surface mount applications in the SC-85 (UMT3F) package. This device features a maximum collector current of 100 mA, operates with a maximum collector-emitter voltage of 50 V, and integrates resistor values of 2.2 kOhms (base) and 47 kOhms (emitter-base). With a transition frequency of 250 MHz and a maximum power dissipation of 200 mW, it is suitable for high-frequency general-purpose switching. The product status is "Not For New Designs," necessitating the identification of equivalent or substitute models for ongoing or new applications where continued availability and support are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection for the DTC123JUBTL is based strictly on matching the electrical and mechanical parameters relevant to its application as a pre-biased NPN BJT in surface mount technology. Key parameters used for equivalence include transistor polarity and type, maximum collector current (Ic), maximum collector-emitter breakdown voltage, integrated bias resistor values (R1, R2), DC current gain, saturation voltage, maximum collector cutoff current, transition frequency, maximum power dissipation, mounting type, and compliance status (RoHS, REACH). Only components meeting all these criteria can be considered as substitutes within the bipolar transistor (BJT) product category.

Parameter Comparison

Engineering Selection Recommendations

The DTC123JUBTL is classified as "Not For New Designs" while the PDTC123JU,115 is marked as "Active." Both devices hold ROHS3 and REACH compliance. Substitution can be based on equivalent environmental and regulatory certifications when continued product support and long-term availability are required.

Frequently Asked Questions (FAQ)

Q: What are the most important criteria when substituting the DTC123JUBTL?
A: The primary criteria are NPN pre-biased configuration, maximum collector current (100 mA), collector-emitter breakdown voltage (50 V), base and emitter-base resistor values (2.2 kOhms / 47 kOhms), power rating (200 mW), mounting type, and compliance to ROHS3/REACH.

Q: Is the package form factor identical between the DTC123JUBTL and PDTC123JU,115?
A: The DTC123JUBTL is supplied in the SC-85 (UMT3F) package; the PDTC123JU,115 is in the SC-70 (SOT-323) package. Both are surface mount, but the physical dimensions and PCB footprints are different and require layout verification.

Q: Is there any difference in bias resistor values between the main part and the substitute?
A: Both devices feature 2.2 kOhms (R1) and 47 kOhms (R2) resistor values.

Q: Are the substitute parts compliant with environmental and hazardous material standards?
A: Both DTC123JUBTL and PDTC123JU,115 are ROHS3 compliant and REACH unaffected.

Q: Can I substitute PDTC123JU,115 in an application designed for DTC123JUBTL without changes?
A: Electrical parameters are matched. However, mechanical compatibility depends on the PCB layout and package footprint. Ensure package differences are reconciled.
