DTC143EUBTL Equivalent & Substitute Parts

Part Overview

The Rohm Semiconductor DTC143EUBTL is a pre-biased NPN bipolar junction transistor (BJT) designed for general-purpose switching operations in compact, surface-mount packages. The product is active and commonly used in applications requiring moderate current and voltage ratings in compact circuits. The need to find alternative models can arise due to inventory shortages, supply chain management, or mechanical compatibility requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on the following key parameters: transistor type, collector current rating (Ic), collector-emitter voltage rating (Vce), both pre-bias resistor values (R1 and R2), DC current gain (hFE) at defined current and voltage, Vce saturation at defined test points, collector cutoff current, transition frequency, maximum power, surface mount compatibility, RoHS compliance, MSL, REACH status, and product status. Substitutes must match or exceed each parameter where specific values are critical to performance or regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both DTC143EUBTL and PDTC143EU,115 are active, ROHS3 compliant, exhibit no moisture sensitivity restrictions (MSL 1, unlimited), and are REACH unaffected. Both devices are classified as EAR99. Selection between these parts can be made based on inventory and package compatibility within the allowed compliance and status requirements.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting DTC143EUBTL with another part?
The main criteria are transistor type, electrical maximum ratings (collector current, collector-emitter voltage), both pre-bias resistor values, DC current gain, saturation voltages, cutoff currents, power capacity, and regulatory compliance (ROHS, REACH, MSL).

Q2: Are the packages mechanically compatible?
The DTC143EUBTL is supplied in an SC-85 (UMT3F) package, while the PDTC143EU,115 uses SC-70 (SOT-323). Compatibility must be determined by comparing the footprint and mounting requirements for each.

Q3: How does device compliance affect substitution?
Both parts meet ROHS3 and REACH standards and have an unlimited moisture sensitivity level (MSL 1), allowing them to be used in lead-free and high-reliability manufacturing processes without restriction.

Q4: Does the saturation voltage difference affect substitution?
Saturation voltage is specified among the key parameters, and both substitute and main part values are within the parameter scope presented.

Q5: Is the current gain consistent between DTC143EUBTL and PDTC143EU,115?
Both parts have the same minimum DC current gain under identical test conditions.

Q6: Is electrical performance matched for general-purpose use?
Electrical performance is matched within all specified input parameters presented.
