Key Parameters

Substitute Part Grouping Explanation

Substitute parts for DTA144VCAT116 are identified strictly according to the following key parameters: transistor type, maximum collector current, maximum collector-emitter breakdown voltage, base/emitter resistor values, DC current gain, saturation voltage, cutoff current, transition frequency, maximum power dissipation, package type, mounting type, and compliance status (RoHS, REACH, MSL). Only parts which match or meet these parameters are considered suitable for substitution within this product category.

Parameter Comparison

Engineering Selection Recommendations

Both DTA144VCAT116 and PDTA144VT,215 are classified as "Active" and comply with ROHS3 and REACH requirements. The Moisture Sensitivity Level for both units is "1 (Unlimited)," indicating suitability for standard surface-mount assembly and storage. Substitution can be performed strictly between devices conforming to the parameters provided: transistor type, voltage, current capability, integrated resistor values, and compliance status. No selection criteria beyond those listed should be considered in the equivalency assessment.

Frequently Asked Questions (FAQ)

Q: What parameters must be strictly matched for substitution between DTA144VCAT116 and alternatives?
A: The required parameters for substitution include transistor type, collector current, collector-emitter breakdown voltage, integrated base and emitter resistor values, package type, mounting type, DC current gain, saturation voltage, cutoff current, transition frequency, maximum power dissipation, RoHS/REACH compliance, and Moisture Sensitivity Level.

Q: Is package compatibility assured between DTA144VCAT116 and PDTA144VT,215?
A: Both transistors utilize surface mount packages, specifically TO-236-3, SC-59, and SOT-23-3. Supplier device package nomenclature may differ, but package form factors are equivalent for direct substitution in compatible PCB footprints.

Q: Are there any compliance or regulatory considerations when selecting a substitute?
A: Both listed parts are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level is "1 (Unlimited)" for both, meeting standard handling and assembly requirements.

Q: How does DC current gain affect substitution?
A: DC current gain should be referenced according to the provided values. Substitution is validated when minimum values at specified test conditions meet or exceed requirements for the given application.

Q: Is there a difference in maximum power dissipation between the two listed parts?
A: DTA144VCAT116 specifies a maximum power of 200 mW, while PDTA144VT,215 specifies 250 mW. Both values should be verified against application power needs but fall within the allowed range for product category substitution.
