Substitute Part Grouping Explanation

Substitution of the BC807-40W/MIF is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

Transistor Type: PNP
Current - Collector (Ic) Max: 500 mA
Voltage - Collector Emitter Breakdown (Max): 45 V
Vce Saturation (Max) @ Ib, Ic: 700 mV @ 50 mA, 500 mA
Current - Collector Cutoff (Max): 100 nA
DC Current Gain (hFE) Min @ Ic, Vce: 250 @ 100 mA, 1 V
Power - Max: 200 mW
Frequency - Transition: 80 MHz
Package / Case: SC-70, SOT-323
Mounting Type: Surface Mount
Grade: Automotive
Qualification: AEC-Q101

Parametric Equivalent Parts maintain all critical electrical and mechanical specifications identical to the main part. These components are direct replacements with no circuit redesign required.

Similar Parts share the same package, transistor type, and primary voltage/current ratings but differ in one or more secondary parameters such as DC current gain, power dissipation, or frequency response. These parts require circuit validation before substitution.

Frequently Asked Questions (FAQ)

Q: Can BC807-40LWF be used as a direct replacement for BC807-40W/MIF?

A: Yes. BC807-40LWF is a parametric equivalent with identical electrical specifications, automotive grade, and AEC-Q101 qualification. The part is active and available in production quantities.

Q: What is the difference between BC807-40W,115 and BC807-40W,135?

A: Both parts are parametric equivalents with identical electrical specifications. The suffix designates packaging format: BC807-40W,115 is supplied in Cut Tape (CT) & Digi-Reel format, while BC807-40W,135 is supplied in Tape & Reel (TR) format. Selection depends on procurement and assembly requirements.

Q: Can BC807-16W RFG replace BC807-40W/MIF in all applications?

A: BC807-16W RFG has a lower DC current gain minimum (100 versus 250 @ 100 mA, 1 V). Substitution is valid only for circuits where the lower current gain does not compromise performance. Circuit validation is required.

Q: What are the advantages of SBC807-40WT1G over BC807-40W/MIF?

A: SBC807-40WT1G maintains identical DC current gain (250 @ 100 mA, 1 V) while providing higher power dissipation (460 mW versus 200 mW) and faster transition frequency (100 MHz versus 80 MHz). It retains automotive grade and AEC-Q101 qualification. This part is suitable for applications requiring enhanced thermal performance or higher switching speeds.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parametric equivalent and similar parts listed are ROHS3 compliant and REACH unaffected.

Q: Does package format affect electrical performance?

A: No. Package format (Cut Tape, Tape & Reel, or alternative supplier designations) does not affect electrical performance. Selection is based on procurement, storage, and assembly process requirements.

Q: Can BC807-25WT1G be used in automotive applications?

A: BC807-25WT1G is not designated as automotive grade and does not carry AEC-Q101 qualification. For automotive applications, use parametric equivalents (BC807-40LWF, BC807-40LWX, BC807-40W,115, BC807-40W,135, BC807-40W-QF, BC807-40W-QX) or SBC807-40WT1G.
