Key Parameters

Substitute Part Grouping Explanation

Substitution is established strictly by matching the following key parameters: transistor type (2 PNP dual), collector-emitter breakdown voltage (50V), maximum collector current (150mA), Vce saturation voltage (500mV @ 5mA, 50mA), collector cutoff current (100nA), DC current gain (hFE min 120 @ 1mA, 6V), transition frequency (140MHz), maximum operating temperature (150°C), mounting type (surface mount), RoHS and REACH compliance, and product status (active). Package and device case are considered for direct replacement compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both IMT2AT108 and UMT1NTN are classified as active products. They fulfill required environmental compliance criteria, including ROHS3 and REACH unaffected status. Moisture Sensitivity Level (MSL) is unlimited for both, confirming suitability for typical soldering environments. ECCN and HTSUS categories are matching, confirming regulatory equivalency.
