Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD85015TR-E is determined by the following critical parameters that must remain compatible:

Package Compatibility: Both the main part and substitute must use PowerSO-10RF Exposed Bottom Pad (2 Formed Leads) packaging to ensure mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Technology Platform: Both parts must utilize LDMOS (Laterally Diffused Metal-Oxide-Semiconductor) technology to maintain electrical performance characteristics and thermal behavior.

Electrical Ratings: Substitute parts must maintain the same rated voltage (40V) and current rating (5A) to ensure safe operation within the design envelope.

Output Power: The substitute must deliver 15W output power to meet application power requirements.

Compliance & Certifications: Both parts must maintain ROHS3 compliance, identical MSL rating (3, 168 Hours), and REACH unaffected status to ensure regulatory and environmental compatibility.

Manufacturer Continuity: Substitutes are limited to STMicroelectronics to maintain design validation and supply chain consistency.

The PD55015TR-E meets all substitution criteria and is designated as the manufacturer-recommended substitute.

Engineering Selection Recommendations

Primary Substitute: PD55015TR-E

The PD55015TR-E is the manufacturer-recommended substitute for the obsolete PD85015TR-E. Both devices share identical package geometry (PowerSO-10RF with formed leads), rated voltage (40V), current rating (5A), test current (150mA), and output power (15W). Both maintain ROHS3 compliance and identical MSL rating (3, 168 Hours).

The PD55015TR-E is classified as active product status, ensuring ongoing availability and supply chain support. This status provides a clear path for design continuity and long-term production support.

Operational Differences:

The PD55015TR-E operates at a lower test voltage (12.5V versus 13.6V) and is optimized for 500MHz operation compared to the 870MHz specification of the PD85015TR-E. The gain specification is 14dB versus 16dB for the main part. These differences reflect frequency-dependent performance characteristics inherent to LDMOS RF MOSFET design.

Compliance Assurance:

Both parts maintain identical regulatory compliance status (ROHS3 compliant, REACH unaffected, ECCN EAR99, HTSUS 8541.29.0095), ensuring no additional compliance documentation or qualification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the PD55015TR-E be used as a direct replacement for the PD85015TR-E?

A: The PD55015TR-E is the manufacturer-recommended substitute and shares identical package geometry, rated voltage, current rating, and output power specifications. Both devices use PowerSO-10RF packaging with formed leads and exposed bottom pad, ensuring mechanical and thermal compatibility with existing PCB designs. However, the frequency response and gain characteristics differ due to the lower operating frequency (500MHz versus 870MHz) and reduced gain (14dB versus 16dB). Application-specific circuit design validation is required to confirm performance in the target frequency band.

Q: Are there any packaging differences between the PD85015TR-E and PD55015TR-E?

A: Both parts use identical packaging: PowerSO-10RF Exposed Bottom Pad with 2 Formed Leads. No PCB layout modifications are required for mechanical compatibility. Both parts maintain the same MSL rating (3, 168 Hours), requiring identical moisture control and handling procedures during assembly.

Q: What is the significance of the voltage and frequency differences?

A: The PD55015TR-E operates at a test voltage of 12.5V compared to 13.6V for the PD85015TR-E, and is optimized for 500MHz operation versus 870MHz. These differences reflect the frequency-dependent characteristics of LDMOS RF MOSFET technology. The rated voltage remains 40V for both devices, ensuring safe operation within the same power supply envelope. Application circuits must be validated to confirm performance at the target operating frequency and voltage.

Q: Are both parts RoHS compliant?

A: Yes. Both the PD85015TR-E and PD55015TR-E are ROHS3 compliant and REACH unaffected. No additional environmental or regulatory qualification is required for substitution.

Q: What is the inventory status of these parts?

A: The PD85015TR-E is classified as obsolete with 1048 pieces in stock. The PD55015TR-E is classified as active product with 2100 pieces in stock, providing superior long-term supply chain availability.

Q: Are there any differences in moisture sensitivity or handling requirements?

A: Both parts carry identical MSL rating of 3 (168 Hours), requiring the same moisture control procedures, baking protocols, and shelf-life management during storage and assembly.
