2SA1774EBTLR Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor 2SA1774EBTLR is a PNP bipolar junction transistor (BJT) in the Transistors, Bipolar (BJT) category. It features a maximum collector-emitter voltage rating of 50 V, a collector current of up to 150 mA, a transition frequency of 140 MHz, and is housed in the EMT3F (SOT-416FL) surface mount package. Its status is Active, with RoHS3 compliance and unlimited MSL rating. The need to identify alternative models arises to ensure uninterrupted production, maintain inventory flexibility, and address design changes or part discontinuation.

Key Parameters

Substitute Part Grouping Explanation

Substitutes are determined using the following strictly-defined key parameters: transistor type (PNP), collector current, collector-emitter breakdown voltage, power rating, DC current gain at a specified operating point, transition frequency, Vce saturation voltage, collector cutoff current, package/case compatibility, mounting type, and compliance/certification details. Only parts matching these criteria within the provided range and packaging can be listed as technical substitutes.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring only Active product status, select 2SA1774EBTLR or 2SAR523EBTL, both being ROHS3 compliant with MSL 1 rating and unaffected REACH status. If usage of components designated Not For New Designs is permitted, 2SA1774EBTLQ matches all key parameters and certifications. Packaging and surface mount compatibility are consistent across all listed part numbers.

Frequently Asked Questions (FAQ)

Q1: What parametric criteria must substitute PNP BJTs meet for equivalence with 2SA1774EBTLR?
A1: Substitute transistors must match key criteria including transistor type (PNP), maximum collector current, collector-emitter breakdown voltage, DC current gain, maximum power rating, cutoff current, transition frequency, mounting type, and package compatibility.

Q2: Are all listed substitute parts compatible with the EMT3F (SOT-416FL) footprint and surface mount process?
A2: Yes. All referenced part numbers are supplied in EMT3F (SOT-416FL) / SC-89, SOT-490 package and are suitable for surface mount assembly.

Q3: Do the substitutes provide matched compliance for RoHS and REACH requirements?
A3: All substitutes, including 2SA1774EBTLR, 2SAR523EBTL, and 2SA1774EBTLQ, are ROHS3 compliant and unaffected by REACH regulations based on the provided information.

Q4: What should be considered regarding product status when selecting substitutes?
A4: Only parts with Active status (such as 2SA1774EBTLR and 2SAR523EBTL) are suitable for ongoing or new designs. Parts marked Not For New Designs (such as 2SA1774EBTLQ) should be selected only if explicitly permitted by project or supply chain constraints.
