EMA2T2R Equivalent & Substitute Parts Reference

Part Overview

The EMA2T2R, manufactured by Rohm Semiconductor, is a dual pre-biased PNP bipolar junction transistor (BJT) designed for surface mount applications in the Transistors, Bipolar (BJT) category. This product features a collector current maximum of 100mA, a voltage rating of 50V, power dissipation of 150mW, and integrated base resistors (R1 and R2). The product maintains an active status and is RoHS3 compliant. Identifying alternative models is necessary to ensure continued sourcing, risk mitigation, and design flexibility in the event of allocation constraints, supply interruptions, or to accommodate multiple approved vendor lists.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected based on strict compliance with essential electrical and mechanical parameters for dual pre-biased PNP bipolar transistors. The substitute part RN2704JE(TE85L,F) matches the following criteria:

• Transistor configuration (2 PNP - Pre-Biased, Dual)
• Maximum collector current (100mA)
• Collector-emitter breakdown voltage (50V)
• Built-in base/emitter resistors (R1 and R2: 47kOhms)
• Surface mount package type
• RoHS compliance
• Active product status

Variations in package size and additional characteristics are documented for engineering assessment.

Parameter Comparison

Engineering Selection Recommendations

Both EMA2T2R and RN2704JE(TE85L,F) maintain active product status, fulfill necessary RoHS environmental compliance, and are at Moisture Sensitivity Level 1 (Unlimited). Either part can be selected for designs where regulatory compliance and supply continuity are critical factors.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to select equivalent or substitute transistors in this category?
A1: Substitution is based on matching transistor configuration, maximum collector current, maximum collector-emitter voltage, integrated resistor values, mounting type, compliance status, and package compatibility where noted.

Q2: How does package / case variation affect substitution?
A2: The main part EMA2T2R is packaged in 6-SMD (5 Leads), Flat Lead (EMT5), while the substitute RN2704JE(TE85L,F) uses SOT-553 (ESV). Design validation should review footprint compatibility before substitution.

Q3: Are all listed substitutes RoHS compliant?
A3: Both the EMA2T2R and RN2704JE(TE85L,F) are compliant with RoHS environmental regulations.

Q4: Do the key electrical ratings match between the EMA2T2R and its substitute?
A4: Both parts match in collector current (100mA), voltage rating (50V), and integrated resistor values (47kOhms). Noted differences include power dissipation, current gain at specified conditions, and transition frequency.

Q5: Are these substitute options actively manufactured and available?
A5: Both the EMA2T2R and RN2704JE(TE85L,F) are listed as "Active" and available in stock in the provided inventory data.
