BC33716TF Equivalent & Substitute Parts

Part Overview

The BC33716TF is an NPN bipolar junction transistor manufactured by onsemi, rated for 45V collector-emitter breakdown voltage and 800mA maximum collector current. This device is packaged in a TO-92-3 through-hole configuration and is currently classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is necessary for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitution of the BC33716TF is determined by strict equivalence across the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Transistor Type: NPN
Current - Collector (Ic) Max: 800 mA
Voltage - Collector Emitter Breakdown (Max): 45 V
Vce Saturation (Max) @ Ib, Ic: 700mV @ 50mA, 500mA
Power - Max: 625 mW
Mounting Type: Through Hole
Package / Case: TO-92-3 (TO-226AA)

Secondary Compatibility Parameters:

DC Current Gain (hFE) Min: 100 or greater
Frequency - Transition: 100 MHz or greater
Operating Temperature: 150°C or greater

Substitute parts must meet or exceed all primary criteria. Variations in secondary parameters indicate enhanced performance characteristics and remain compatible with applications designed for the BC33716TF.

Engineering Selection Recommendations

BC33716TA (Fairchild Semiconductor) is the primary substitute for BC33716TF. This part maintains identical electrical specifications across all critical parameters and is currently in active production status. The BC33716TA provides design continuity with no performance degradation and ensures long-term component availability.

BC337-25-AP (Micro Commercial Co) is a secondary substitute option. This part meets all primary substitution criteria with enhanced performance characteristics: higher DC current gain (160 vs. 100), increased transition frequency (210 MHz vs. 100 MHz), and extended operating temperature range (-55°C to 150°C vs. 150°C maximum). The BC337-25-AP is supplied in Cut Tape packaging and is RoHS3 compliant. However, this part is classified as obsolete, which may limit long-term availability.

For new designs and ongoing production requiring maximum component availability, BC33716TA is the recommended selection. For applications requiring enhanced frequency response or wider temperature operating range, BC337-25-AP provides superior electrical performance within the same package and power envelope.

Frequently Asked Questions (FAQ)

Q: Can BC33716TA directly replace BC33716TF without circuit modification?

A: Yes. BC33716TA maintains identical electrical specifications for all critical parameters including collector current, breakdown voltage, saturation voltage, power dissipation, and transition frequency. Direct substitution is supported without circuit redesign.

Q: What is the difference between BC33716TA and BC337-25-AP?

A: Both parts meet the core electrical requirements of BC33716TF. BC337-25-AP offers enhanced performance with higher DC current gain (160 vs. 100), faster transition frequency (210 MHz vs. 100 MHz), and wider operating temperature range (-55°C to 150°C). BC33716TA maintains exact specification matching to the original part.

Q: Are there packaging differences between these substitutes?

A: BC33716TF and BC33716TA are both supplied in standard TO-92-3 through-hole packaging. BC337-25-AP is supplied in Cut Tape packaging but uses the same TO-92-3 component form factor. All three parts are mechanically compatible with existing PCB layouts designed for TO-92-3 devices.

Q: Why is BC33716TF classified as obsolete?

A: Product status reflects manufacturer discontinuation decisions. BC33716TA, manufactured by Fairchild Semiconductor, remains in active production and provides equivalent functionality for applications currently using BC33716TF.

Q: Which substitute should be selected for new product designs?

A: BC33716TA is recommended for new designs due to its active production status and guaranteed long-term availability. This ensures component supply continuity throughout the product lifecycle.

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

A: BC337-25-AP carries RoHS3 compliance certification. All three parts are REACH unaffected and classified under ECCN EAR99. Compliance requirements for specific applications should be verified against end-use regulations.
