Engineering Selection Recommendations

The 2N5192G from onsemi is the direct equivalent substitute for the obsolete 2N5192 from STMicroelectronics. Selection of the 2N5192G is based on the following factors:

Product Status: The 2N5192G maintains active product status, ensuring ongoing availability and manufacturing support. The original 2N5192 is classified as obsolete, creating supply chain risk for new production and field repairs.

Electrical Equivalence: All critical electrical parameters—collector current, breakdown voltage, saturation characteristics, current gain, power rating, and transition frequency—are identical between the two devices. This ensures drop-in functional compatibility without circuit redesign.

Mechanical Compatibility: Both devices utilize through-hole mounting in TO-225AA and TO-126-3 packages, permitting direct physical substitution on existing printed circuit boards without layout modification.

Regulatory Compliance: The 2N5192G maintains ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the original part. Both devices carry EAR99 export classification.

Operating Temperature Range: The 2N5192G specifies an extended operating temperature range (−65 °C to 150 °C) compared to the 2N5192 (150 °C maximum junction temperature), providing additional thermal margin in applications requiring low-temperature operation.
