EMA11T2R Equivalent & Substitute Parts Reference

Part Overview

The EMA11T2R by Rohm Semiconductor is a dual pre-biased PNP bipolar junction transistor (BJT) in a surface-mount EMT5 package. The device is characterized by a 50V collector-emitter breakdown voltage, a maximum collector current of 100mA, specific on-chip bias resistors, and a 150mW maximum power dissipation. Its product status is "Not For New Designs," making it necessary to identify electrically and mechanically compatible substitute parts for ongoing production and support needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EMA11T2R are determined by matching essential electrical and mechanical parameters: transistor type, maximum collector current, collector-emitter breakdown voltage, on-chip bias resistor values (R1, R2), DC current gain, saturation voltage, collector cutoff current, transition frequency, maximum power dissipation, mounting type, and RoHS/MSL compliance. Only parts fully aligning with these parameters are considered substitutes in this product category.

Parameter Comparison

Engineering Selection Recommendations

The EMA11T2R is listed as "Not For New Designs," while RN2706JE(TE85L,F) and RN2906,LF are both "Active." All parts are ROHS3 compliant and have an MSL of 1 (Unlimited). REACH status is unaffected for EMA11T2R and RN2906,LF. Selection should prioritize currently active and compliant substitutes for ongoing and future application requirements.

Frequently Asked Questions (FAQ)

Q: What criteria are used to determine equivalency for EMA11T2R substitute parts?
A: Equivalency is based strictly on transistor type, collector current and breakdown voltage ratings, integrated bias resistor values, minimum DC current gain, Vce saturation, collector cutoff current, transition frequency, power dissipation, mounting type, compliance, and package compatibility.

Q: Are the package types and footprints directly interchangeable?
A: The package types differ: EMT5 (6-SMD, 5 leads) for EMA11T2R, SOT-553 (ESV) for RN2706JE(TE85L,F), and 6-TSSOP (US6) for RN2906,LF. Mechanical footprint compatibility must be confirmed based on the specific PCB layout and application requirements.

Q: Do all substitute parts meet RoHS and MSL compliance requirements?
A: All compared parts are ROHS3 compliant and rated MSL 1 (Unlimited), supporting lead-free and standard manufacturing processes.

Q: Can these substitutes be used in place of EMA11T2R without changes to electrical design?
A: Substitute selection is limited to parts matching key electrical parameters, ensuring compatibility in function; confirm mechanical package compatibility during component selection.

Q: Which substitute part numbers are currently active for new designs?
A: RN2706JE(TE85L,F) and RN2906,LF are both listed as Active. EMA11T2R is Not For New Designs.
