EMD2T2R Equivalent & Substitute Parts Reference

Part Overview

The EMD2T2R, manufactured by Rohm Semiconductor, is a dual pre-biased bipolar transistor (BJT) consisting of 1 NPN and 1 PNP transistor with integrated biasing resistors, designed for surface mount applications. This device is categorized under "Transistors, Bipolar (BJT)" and comes in SOT-563 and SOT-666 packages. It features a maximum collector current of 100mA, a maximum collector-emitter voltage of 50V, and symmetrical integrated resistors (22kΩ base and emitter-base). The product is RoHS3 compliant, REACH unaffected, and has a moisture sensitivity level (MSL) of 1.

Despite its active status and substantial inventory, identifying equivalent and substitute models is essential to support sourcing flexibility, mitigate supply chain risk, and ensure form-fit-function interchangeability for this product category.

Substitute Part Grouping Explanation

Substitution is based strictly on the following key parameters:

Transistor Type: 1 NPN, 1 PNP - Pre-Biased (Dual)
Maximum Collector Current (Ic)
Maximum Collector-Emitter Breakdown Voltage
Integrated Base and Emitter-Base Resistor Values (R1 and R2)
DC Current Gain (hFE) at specified collector current and voltage
Vce Saturation Voltage at specified base and collector current
Maximum Collector Cutoff Current
Power Dissipation Capability
Package / Case and Mounting Type
Compliance (RoHS, REACH) and Moisture Sensitivity Level (MSL)
Product Status

Only parts that meet all these explicit parameters are listed as direct substitutes or equivalents.

Engineering Selection Recommendations

Component selection for EMD2T2R equivalents and substitutes is governed by product status and compliance only. EMD2T2R and NSBC124EPDXV6T1G are both listed as Active and are RoHS3 compliant with MSL 1 (Unlimited) and REACH Unaffected status. PEMD2,115 is designated Not For New Designs, and although it meets compliance criteria, it may not be preferred for new design qualification purposes based solely on product status.

Frequently Asked Questions (FAQ)

Q1: What determines if a part is an equivalent or direct substitute in this BJT category?
A1: Equivalency is determined by matching transistor configuration (1 NPN, 1 PNP - Pre-Biased), maximum collector current, collector-emitter voltage, integrated resistor values, DC current gain at specified test conditions, saturation voltage, cutoff current, power rating, package/case, supplier device package, and compliance certifications.

Q2: Are the pinouts and packages interchangeable for EMD2T2R, PEMD2,115, and NSBC124EPDXV6T1G?
A2: All listed parts are available in SOT-563 or SOT-666 packaging and are specified as surface mount. Package compatibility should be verified based on SOT-563 and SOT-666 industry standards as listed in the input data.

Q3: Which substitute is preferred based on product status?
A3: NSBC124EPDXV6T1G and EMD2T2R are Active. PEMD2,115 is Not For New Designs.

Q4: Is RoHS or REACH compliance consistent across substitutes?
A4: All compared parts are RoHS3 Compliant and REACH Unaffected with an MSL of 1 (Unlimited).
