Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD85025STR-E is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Technology: LDMOS
• Frequency: 870MHz
• Voltage - Test: 13.6V
• Voltage - Rated: 40V
• Package / Case: PowerSO-10RF Exposed Bottom Pad (2 Straight Leads)
• RoHS Status: ROHS3 Compliant
• MSL Rating: 3 (168 Hours)

Allowable Parameter Variations: Substitute parts may exceed the original specifications in current rating, test current, power output, and gain, provided all mandatory parameters remain identical. The PD85035STR-E meets all mandatory matching criteria while providing enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The PD85035STR-E is the direct substitute for the obsolete PD85025STR-E. Both devices share identical core specifications across technology, frequency, test voltage, rated voltage, package configuration, and compliance certifications. The PD85035STR-E maintains active product status with STMicroelectronics, ensuring continued availability and supply chain reliability.

The PD85035STR-E provides enhanced performance with increased current rating (8A versus 7A), higher test current (350mA versus 300mA), and greater power output (15W versus 10W). These improvements are compatible with circuit designs originally specified for the PD85025STR-E, as the substitute operates within the same voltage and frequency parameters.

Both devices maintain ROHS3 compliance and identical moisture sensitivity levels, ensuring compatibility with existing manufacturing and storage protocols. The PD85035STR-E is available in Tape & Reel packaging, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the PD85035STR-E directly replace the PD85025STR-E in existing circuit designs?

A: Yes. The PD85035STR-E is electrically and mechanically compatible with the PD85025STR-E.
