2PB709ART,235 Equivalent & Substitute Parts

Part Overview

The 2PB709ART,235 is a surface mount PNP bipolar junction transistor manufactured by Nexperia USA Inc. in the TO-236AB package. This device operates at 45 V collector-emitter breakdown voltage with a maximum collector current of 100 mA and is qualified to AEC-Q101 automotive standards. The part is active and in production with 731 pieces currently in stock.

Substitute parts are necessary when the primary device becomes unavailable, when alternative manufacturers offer improved lead times, or when design flexibility requires selection from multiple qualified sources while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the 2PB709ART,235 is determined by the following critical parameters:

Electrical Compatibility Requirements:

Transistor type must be PNP
Voltage - Collector Emitter Breakdown must be 45 V or greater
Current - Collector (Ic) maximum must be equal to or greater than 100 mA
Power dissipation must be equal to or greater than 250 mW
Frequency - Transition must be equal to or greater than 70 MHz

Mechanical Compatibility Requirements:

Package / Case must be TO-236-3, SC-59, or SOT-23-3
Mounting type must be Surface Mount
Operating temperature range must include 150°C maximum

Compliance Requirements:

RoHS3 compliance required
Moisture Sensitivity Level (MSL) of 1 (Unlimited) required

All substitute parts listed meet or exceed these parameters. Substitute parts with higher current ratings (500 mA) and higher power dissipation (300–310 mW) are electrically compatible and provide additional design margin. Substitute parts with higher DC current gain (hFE) values provide enhanced performance characteristics while maintaining backward compatibility.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Selection among substitute parts is based on the following factors:

Current Availability: onsemi BC807-25LT1G offers the highest inventory level (293,400 pieces), followed by BC807-25LT3G (305,300 pieces), providing supply chain stability for high-volume applications.

Packaging Consistency: Parts designated with SOT-23-3 (TO-236) package designation, including BC807-16LT1G, BC807-16LT3G, BC807-25LT1G, and BC807-25LT3G, maintain mechanical compatibility with the original TO-236AB package footprint.

Electrical Performance Margin: All substitute parts exceed the 2PB709ART,235 specifications in collector current (500 mA versus 100 mA) and transition frequency (100 MHz versus 70 MHz), providing additional design margin for signal amplification and switching applications.

DC Current Gain Variants: BC807-16 variants provide hFE minimum of 100, BC807-25 variants provide hFE minimum of 160, and BC807-40 variants provide hFE minimum of 250. Selection depends on required amplification characteristics for the specific circuit application.

Manufacturer Options: Diodes Incorporated, Micro Commercial Co, and onsemi all provide qualified alternatives with active product status and equivalent electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can BC807 series transistors directly replace the 2PB709ART,235 in existing designs?

A: Yes. All BC807 variants listed meet or exceed the electrical and mechanical specifications of the 2PB709ART,235. The TO-236-3 / SOT-23-3 package footprint is identical, enabling direct PCB substitution without layout modification.

Q: What is the difference between BC807-16, BC807-25, and BC807-40 variants?

A: The numeric suffix indicates the DC current gain (hFE) classification. BC807-16 has hFE minimum of 100, BC807-25 has hFE minimum of 160, and BC807-40 has hFE minimum of 250. All three variants are electrically compatible with the 2PB709ART,235 and with each other.

Q: Are there differences between Diodes Incorporated, Micro Commercial Co, and onsemi BC807 parts?

A: All three manufacturers produce BC807 transistors meeting identical electrical specifications. Differences exist in packaging format (Tape & Reel versus Cut Tape & Digi-Reel), current collector cutoff specifications (100 nA versus 200 nA), and power dissipation (300 mW versus 310 mW). These differences do not affect functional compatibility.

Q: Why do substitute parts have higher current ratings (500 mA) than the original part (100 mA)?

A: Higher current ratings provide additional design margin and allow the substitute part to function in applications requiring greater collector current. The 2PB709ART,235 can be replaced with a 500 mA rated device without circuit modification, as the circuit design determines actual current draw.

Q: Is the 2PB709ART,235 automotive qualified?

A: Yes. The 2PB709ART,235 carries AEC-Q101 qualification. Substitute BC807 parts do not explicitly list AEC-Q101 qualification in the provided data. For automotive applications requiring AEC-Q101 certification, verify manufacturer documentation before substitution.

Q: What is the operating temperature range for substitute parts?

A: All BC807 substitute parts operate from −55°C to 150°C junction temperature, which exceeds the 2PB709ART,235 maximum operating temperature of 150°C and provides extended low-temperature performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status and unlimited moisture sensitivity level (MSL 1), matching the environmental and regulatory requirements of the 2PB709ART,235.
