Key Parameters
| Manufacturer Part Number | Transistor Type | Voltage - Collector Emitter Breakdown (Max) | Current - Collector (Ic) (Max) | Vce Saturation (Max) @ Ib, Ic | Current - Collector Cutoff (Max) | DC Current Gain (hFE) (Min) @ Ic, Vce | Power - Max | Frequency - Transition | Operating Temperature | Mounting Type | Package / Case | Supplier Device Package | RoHS Status |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| EMT52T2R | 2 PNP (Dual) | 50V | 100mA | 400mV @ 5mA, 50mA | 100nA (ICBO) | 120 @ 1mA, 6V | 150mW | 300MHz | 150°C (TJ) | Surface Mount | SOT-563, SOT-666 | EMT6 | ROHS3 Compliant |
Substitute Part Grouping Explanation
Substitute transistor selection for EMT52T2R is strictly based on these parameters: transistor type (2 PNP dual configuration), maximum collector-emitter breakdown voltage, maximum collector current, saturation voltage, cutoff current, minimum DC gain, power dissipation, transition frequency, maximum junction temperature, mounting style, package, and RoHS status. Each substitute provided matches these critical functional, mechanical, and compliance attributes.

Engineering Selection Recommendations
EMT52T2R is active and ROHS3 compliant, suitable for ongoing designs. Substitute BC857BV,115 is also ROHS3 compliant and matches the mounting, package, transistor type, and essential electrical parameters; however, it is classified as "Not For New Designs." Selection should consider the product status for long-term availability in new applications, and part compliance and qualification requirements per project specification.
Frequently Asked Questions (FAQ)
Q: Which key parameters must match for substitution in bipolar transistor arrays like EMT52T2R?
A: Transistor type, maximum collector-emitter voltage, maximum collector current, saturation voltage, cutoff current, minimum DC current gain, power dissipation, transition frequency, operating temperature, mounting type, package/case, and RoHS status.
Q: Is BC857BV,115 drop-in compatible with EMT52T2R from an electrical and mechanical perspective?
A: BC857BV,115 matches transistor type, mounting style, and package/case. Electrical parameters such as current and voltage ratings are also compatible as specified.
Q: Can substitute parts be used in designs requiring ROHS compliance?
A: Both EMT52T2R and BC857BV,115 are ROHS3 compliant.
Q: What considerations apply regarding product lifecycle and qualification?
A: EMT52T2R is active; BC857BV,115 is not recommended for new designs. Consider current status and qualification (e.g., AEC-Q101 for automotive) in selection.
Q: Are the packages SOT-563, SOT-666, and EMT6 equivalent for PCB layout?
A: Both EMT52T2R and BC857BV,115 are available in SOT-563 and SOT-666-compatible formats as indicated. Supplier-specific package codes (EMT6, SOT-666) refer to similar outlines as defined. Evaluate dimensional data per the provided package/case parameter.
