EMB4T2R Equivalent & Substitute Parts Reference

Part Overview

The EMB4T2R from Rohm Semiconductor is an active surface-mount dual pre-biased PNP bipolar transistor (BJT) in the SOT-563, SOT-666 package, with a maximum collector current of 100mA, a collector-emitter breakdown voltage of 50V, an R1 base resistor of 10kOhms, 150mW power dissipation, and a transition frequency of 250MHz. Alternative models or substitutes are necessary in applications requiring supply chain resilience, multi-source qualification, or when facing lead-time or inventory constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EMB4T2R are selected based strictly on identical or compatible electrical and mechanical parameters. Validation is based on the following:

• Transistor Type: 2 PNP - Pre-Biased (Dual)
• Maximum Collector Current (Ic): 100mA
• Maximum Collector-Emitter Breakdown Voltage: 50V
• Base Resistor (R1): 10kOhms
• DC Current Gain (hFE) (Minimum, Test Conditions Provided)
• Maximum Vce Saturation
• Frequency - Transition
• Power Dissipation (Max)
• Mounting Type and Package / Case
• Compliance (RoHS, MSL)
• Product Status

All substitute parts listed meet these explicit criteria as required for direct substitution within this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the EMB4T2R and RN2911FE(TE85L,F) are in active production and have RoHS-compliant and unlimited MSL ratings. Both parts are supplied in surface-mount SOT-563, SOT-666-compatible packaging and comply with relevant environmental regulations. Selections between these models can be based on part availability and supply chain continuity, as both conform to the documented compliance and status requirements.

Frequently Asked Questions (FAQ)

Q1: What parameters determine if RN2911FE(TE85L,F) is a substitute for EMB4T2R?
A1: Substitutability is determined by identical or compatible transistor type, maximum collector current, maximum collector-emitter breakdown voltage, base resistor value, DC current gain (minimum), maximum Vce saturation, frequency transition, power rating, package compatibility, RoHS compliance, moisture sensitivity level, and active product status.

Q2: Are the SOT-563, SOT-666, EMT6, and ES6 packages cross-compatible?
A2: Both the EMB4T2R and RN2911FE(TE85L,F) are specified as available in SOT-563 and SOT-666 packages. Device-specific package codes EMT6 and ES6 correspond to these industry-standard footprints, supporting mechanical compatibility for surface mounting.

Q3: Does substituting these parts impact compliance with RoHS or MSL requirements?
A3: Both parts are compliant with RoHS and have a moisture sensitivity level (MSL) of 1 (Unlimited), maintaining equivalent environmental and handling requirements.

Q4: Is there a difference in availability or product status?
A4: Both the EMB4T2R and RN2911FE(TE85L,F) are listed as active products, with provided inventory quantities. Selection can be based on supply chain and inventory needs as status and compliance are equivalent.

Q5: Can these substitute parts be used in the same circuit designs without modification?
A5: Based strictly on the provided parameters—electrical ratings, gain characteristics, package format, and environmental compliance—the substitute part RN2911FE(TE85L,F) fulfills the documented requirements for use in equivalent circuit footprints where EMB4T2R is specified.
