Parameter Comparison

Engineering Selection Recommendations

PD55025-E is the direct equivalent substitute for the obsolete PD55025. Both parts are manufactured by STMicroelectronics and share identical electrical specifications, mechanical packaging, and regulatory compliance certifications.

The primary distinction is product status: PD55025-E maintains Active status with current manufacturing and supply availability, whereas PD55025 is classified as Obsolete. The PD55025-E is supplied in Tube packaging, whereas the original part packaging specification was not provided.

All electrical parameters, including RF performance (500MHz frequency, 14.5dB gain, 25W output power), voltage ratings (12.5V test, 40V rated), and current specifications (7A rating, 200mA test) are identical between the two parts. Mechanical compatibility is maintained through identical PowerSO-10 Exposed Bottom Pad packaging. Environmental and regulatory compliance remains equivalent: both parts are ROHS3 Compliant, REACH Unaffected, and carry identical Moisture Sensitivity Level 3 (168 Hours) ratings.

Direct substitution of PD55025-E for PD55025 requires no circuit modifications, PCB layout changes, or performance re-qualification.
