Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute pre-biased dual bipolar transistors are grouped based solely on strict matching of the following key parameters: transistor configuration (1 NPN, 1 PNP - Pre-Biased Dual), maximum collector current (100mA), maximum collector-emitter breakdown voltage (50V), base and emitter resistor values (10kOhms each), minimum DC current gain, mounting type, package compatibility (SOT-563/SOT-666), and compliance certifications. This ensures electrical, thermal, and mechanical compatibility without deviating from provided specifications.

Parameter Comparison

Engineering Selection Recommendations

The EMD3T2R, PEMD3,115, and NSBC114EPDXV6T1G transistors all provide ROHS3, MSL 1 (Unlimited), and REACH compliance. The EMD3T2R and NSBC114EPDXV6T1G are listed as active products, while the PEMD3,115 is not for new designs. Selection should prioritize active status and compliance designations for ongoing production and regulatory requirements. Ensure that inventory levels meet project needs according to provided stock status.

Frequently Asked Questions (FAQ)

Q: Which electrical parameters are required to match for substitution among bipolar pre-biased dual transistors?
A: Substitution requires strict matching of the following: transistor type (1 NPN + 1 PNP, pre-biased dual), maximum collector current, maximum collector-emitter voltage, base/emitter resistors, DC current gain, collector cutoff current, saturation voltage, power rating, mounting type, and package.

Q: Are SOT-563 and SOT-666 packages interchangeable for these substitute parts?
A: All listed parts support SOT-563 and SOT-666 packages, allowing direct substitution within designs using these footprints.

Q: Are there any compliance considerations when selecting a substitute part?
A: All alternatives listed are ROHS3 compliant, MSL 1 (Unlimited), and REACH unaffected, ensuring global regulatory compatibility.

Q: How does product status affect substitute selection?
A: Active products are preferred for substitutions to guarantee ongoing availability and manufacturer support. PEMD3,115 is noted as not for new designs.

Q: Can differences in DC current gain and power ratings affect compatibility?
A: Substitution is based on provided minimum DC gain and power ratings; values for all listed parts meet or exceed the requirements according to provided input. Only compare parameters explicitly listed above.
