Key Parameters

Substitute Part Grouping Explanation

Substitute selection for the EMA8T2R is strictly based on matching the following key parameters: transistor configuration, maximum collector current, maximum collector-emitter voltage, integrated resistor values, surface mounting compatibility, and compliance for RoHS and MSL ratings. Only parts conforming to these direct specifications are included as equivalency candidates in the “Transistors, Bipolar (BJT)” category.

Parameter Comparison

Engineering Selection Recommendations

EMA8T2R is designated “Not For New Designs,” making substitute selection necessary for future-proof development. The RN2707JE(TE85L,F) is listed as “Active,” and both parts comply with RoHS and are assigned MSL 1. Substitution ensures continued certification alignment and inventory viability without deviation from regulatory status.

Frequently Asked Questions (FAQ)

Q1: What are the critical electrical parameters that must match for substituting EMA8T2R?
A1: Transistor type, maximum collector current, collector-emitter breakdown voltage, base/emitter resistor values, power rating, and mounting style.

Q2: How do mounting types and package choices affect substitution?
A2: Both EMA8T2R and RN2707JE(TE85L,F) are designed for surface mount applications but differ in package outlines (EMT5 vs. ESV/SOT-553). Pin compatibility and footprint should be evaluated for direct PCB replacement.

Q3: Is compliance with RoHS and MSL mandatory in substitutions?
A3: Yes, equivalent parts must fulfill the same RoHS and Moisture Sensitivity Level ratings for regulatory and manufacturing conformity.

Q4: Are there differences in DC current gain or cutoff current that affect the equivalency?
A4: DC current gain and cutoff current values should be considered only within the provided specifications, ensuring the substitute meets the circuit’s performance requirements as described.

Q5: Can RN2707JE(TE85L,F) be used for new designs as a direct replacement for EMA8T2R?
A5: RN2707JE(TE85L,F) is listed as “Active,” making it suitable for inclusion in new designs where identical key parameters are required.
