2SA1774EBTLP Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor 2SA1774EBTLP is a PNP bipolar junction transistor (BJT) used in general-purpose amplification and switching applications. It is rated at 50 V collector-emitter breakdown voltage, 150 mA collector current, with a 150 mW maximum power dissipation, and packaged for surface mount assembly in the EMT3F (SOT-416FL) outline. The 2SA1774EBTLP is currently marked as "Not For New Designs," meaning its use in new projects is discouraged due to long-term availability concerns. Identifying alternative models is essential to ensure ongoing support and procurement for both active and legacy assemblies where this transistor is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute and equivalent bipolar transistor models are determined strictly by matching critical electrical and mechanical parameters. For the 2SA1774EBTLP, the key substitution criteria are: PNP polarity, collector-emitter breakdown voltage of at least 50 V, maximum collector current of at least 100 mA, DC gain (hFE) minimum of 120 @ 1mA, 6V, maximum power dissipation of 150 mW, matching package/footprint (EMT3F, SOT-416FL, SC-89, SOT-490), and equivalent compliance (RoHS, REACH, MSL). Only derivatives or models with explicit parametric equivalence and identical or higher levels of regulatory compliance are considered substitutes.

Engineering Selection Recommendations

Selection among the listed equivalent and substitute transistor part numbers (2SAR523EBTL, 2SA1774EBTLQ, 2SA1774EBTLR) is supported by their RoHS3 compliance, REACH-unaffected status, and MSL 1 (unlimited) ratings. All are compatible with existing surface mount reflow processes and meet current environmental and regulatory requirements. Differences in product status ("Active" vs "Not For New Designs") should be considered for long-term sourcing continuity.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for qualifying a substitute for the 2SA1774EBTLP?
A1: Substitution is based on PNP polarity, maximum collector-emitter voltage, collector current rating, power dissipation, DC gain, package outline, and full regulatory compliance.

Q2: Are there any differences in mounting or package between the 2SA1774EBTLP and its substitutes?
A2: All substitutes use the SC-89, SOT-490 / EMT3F (SOT-416FL) surface mount package, matching the original footprint and process compatibility.

Q3: Is it necessary to consider RoHS and REACH status when selecting a substitute?
A3: Yes, compliance with ROHS3 and REACH requirements is mandatory for environmental and regulatory acceptance in most modern assemblies.

Q4: How does product status affect substitution?
A4: Selecting substitutes with an "Active" status supports ongoing manufacturing and minimization of future supply chain interruptions.

Q5: Can 2SAR523EBTL be directly implemented as a substitute for all electrical applications of 2SA1774EBTLP?
A5: 2SAR523EBTL matches all provided electrical and package parameters but has a collector current rating of 100 mA. Applications requiring up to 150 mA collector current should use a substitute with a matching current rating, such as 2SA1774EBTLQ or 2SA1774EBTLR.
