SQ2309ES-T1_GE3 Equivalent & Substitute Parts

Part Overview

The SQ2309ES-T1_GE3 is a P-Channel 60V 1.7A MOSFET manufactured by Vishay Siliconix, part of the TrenchFET® series. This device is packaged in SOT-23-3 (TO-236) surface mount configuration and is designed for applications requiring P-channel switching and amplification in low-power circuits. The part is currently in active inventory status with 71,400 units available. Substitute parts are necessary when original stock becomes unavailable, when alternative packaging formats are required, or when supply chain optimization is needed while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SQ2309ES-T1_GE3 is based on strict electrical and mechanical parameter matching within the TrenchFET® product family. The following criteria determine valid substitutes:

Electrical Parameters (Must Match):

• FET Type: P-Channel
• Drain to Source Voltage (Vdss): 60V
• Continuous Drain Current (Id) @ 25°C: 1.7A (Tc)
• Power Dissipation (Max): 2W (Tc)
• Operating Temperature Range: -55°C to 175°C (TJ)

Mechanical Parameters (Must Match):

• Package Type: SOT-23-3 (TO-236)
• Mounting Type: Surface Mount

Allowed Variation:

• Packaging format (tape reel, cut tape, bulk) does not affect electrical or mechanical compatibility
• Product status changes (such as Last Time Buy designation) do not affect functional substitution

The substitute part SQ2309ES-T1_BE3 meets all electrical and mechanical requirements and is therefore a valid equivalent.

Parameter Comparison

Engineering Selection Recommendations

SQ2309ES-T1_GE3 (Primary Selection): Select this part number when active inventory status is required for long-term production runs or when supply continuity is a critical requirement. This part maintains standard active product status with 71,400 units in stock.

SQ2309ES-T1_BE3 (Substitute Selection): This part is electrically and mechanically identical to the primary part and is suitable for immediate substitution in all applications where SQ2309ES-T1_GE3 is specified. The Last Time Buy status indicates limited future availability; therefore, this part should be selected only when the primary part is unavailable or when existing inventory must be consumed. Both parts carry AEC-Q101 automotive qualification and ROHS3 compliance, ensuring equivalent reliability and regulatory status.

The choice between these parts is driven by supply chain availability and inventory management rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can SQ2309ES-T1_BE3 be used as a direct replacement for SQ2309ES-T1_GE3 in production?

A: Yes. Both parts are identical in electrical performance and mechanical form factor. The only difference is packaging format (cut tape versus unspecified format) and product status. All electrical parameters, including Vdss, Id, power dissipation, and operating temperature range, are identical.

Q: What does "Last Time Buy" status mean for SQ2309ES-T1_BE3?

A: Last Time Buy indicates that the manufacturer will no longer produce this part after existing inventory is depleted. This designation does not affect the part's functionality or reliability. It is a supply status indicator only.

Q: Are there any compliance or certification differences between these parts?

A: Both parts carry identical certifications where specified in the provided data: AEC-Q101 automotive qualification and ROHS3 compliance. No compliance differences exist.

Q: Does the packaging format (cut tape) affect circuit performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and mechanical performance is identical regardless of whether the part is supplied in cut tape, reel, or bulk format.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use the identical SOT-23-3 (TO-236) package and surface mount configuration. No PCB layout or assembly process modifications are required when substituting between these part numbers.

Q: What is the base product number for these parts?

A: The base product number is SQ2309. Both SQ2309ES-T1_GE3 and SQ2309ES-T1_BE3 are variants of this base product with identical electrical specifications.
