EMX2T2R Equivalent & Substitute Parts Engineering Reference

Part Overview

The EMX2T2R from Rohm Semiconductor is a bipolar (BJT) transistor array featuring two NPN (dual) transistors, with a maximum collector-emitter voltage of 50V, a maximum collector current of 150mA, and packaged for surface mount applications in SOT-563, SOT-666/EMT6 formats. The part number is actively available and RoHS compliant. Seeking alternative or equivalent models may be necessary due to supply chain management, lead time optimization, or preferred manufacturer policies.

Substitute Part Grouping Explanation

Substitute parts for the EMX2T2R are determined based strictly on the matching of the following key parameters:

Transistor configuration (2 NPN (Dual))
Maximum Collector-Emitter Breakdown Voltage
Maximum Collector Current
Vce Saturation Voltage at specified Ib and Ic
Maximum Collector Cutoff Current (ICBO)
Minimum DC Current Gain at defined Ic and Vce
Power Dissipation
Transition Frequency
Maximum Junction Temperature
Mounting type and package/case format
RoHS and environmental compliance status
Product life cycle status

Only parts that share these key features or fall within defined allowable ranges for their parameters and packaging in this product category are included as substitutes.

Engineering Selection Recommendations

Select only substitute parts marked as "Active" for applications requiring guaranteed long-term supply. Parts that are "Not For New Designs" (such as PMP4201V,115 and PMP4501V,115) are intended for existing designs only. All listed substitute parts are ROHS3 compliant and share an unlimited moisture sensitivity level (MSL 1). Package and supplier device package compatibility must be verified based on the physical layout.

Frequently Asked Questions (FAQ)

Q: Which key parameters must always match when selecting a substitute for EMX2T2R?
A: Transistor configuration, voltage and current ratings, Vce saturation characteristics, current gain, power dissipation, transition frequency, operating temperature, mounting type, package/case, RoHS status, and product activity status must all be matched as per project requirements.

Q: Are all substitutes in the same package as the EMX2T2R?
A: Substitutes such as EMX1T2R match the SOT-563, SOT-666/EMT6 format, while others such as PUMX2,115 use 6-TSSOP, SC-88, or SOT-363. Package compatibility should be verified in the PCB design.

Q: Is product status important for substitute selection?
A: Yes, parts not designated "Active" (such as those marked "Not For New Designs") should only be used for sustaining existing designs, not for new product qualifications.

Q: What regulatory or compliance factors should be considered?
A: All substitutes listed are ROHS3 compliant and have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), aligning with environmental and reliability requirements for most manufacturing processes.

Q: How does collector current or voltage difference affect substitution?
A: Substitute parts must have collector current and voltage ratings at or above the requirements for the intended application, or within defined safe margins as accepted in the product's technical category. Only specified parameter values are used for comparison.
