Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD85015STR-E is determined by the following critical parameters that must remain constant or compatible:

Fixed Electrical Parameters:

• Technology: LDMOS
• Frequency: 870 MHz
• Voltage - Test: 13.6 V
• Voltage - Rated: 40 V
• Power - Output: 15 W
• Package / Case: PowerSO-10RF Exposed Bottom Pad (2 Straight Leads)

Variable Parameters Allowing Substitution:

• Current Rating (Amps): May increase
• Current - Test (mA): May increase
• Gain (dB): May increase

The PD85035STR-E qualifies as a direct substitute because it maintains identical frequency, test voltage, rated voltage, output power, and package specifications. The substitute part exhibits improved performance characteristics with higher current ratings and gain, making it functionally compatible for the same application space while offering enhanced electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The PD85035STR-E is the qualified substitute for the obsolete PD85015STR-E based on the following engineering criteria:

Product Status Alignment: The PD85035STR-E maintains active product status, ensuring continued availability and manufacturing support. The PD85015STR-E is classified as obsolete, making the PD85035STR-E the appropriate selection for new designs and production continuity.

Compliance Certification: Both components maintain identical RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement. Moisture sensitivity levels are equivalent at MSL 3 (168 Hours), requiring identical handling and storage protocols.

Electrical and Mechanical Compatibility: The substitute part maintains identical frequency (870 MHz), test voltage (13.6 V), rated voltage (40 V), output power (15 W), and package configuration (PowerSO-10RF Exposed Bottom Pad with 2 Straight Leads). These fixed parameters ensure direct functional compatibility in existing circuit designs.

Performance Enhancement: The PD85035STR-E provides improved electrical performance with increased current rating (8 A versus 5 A) and higher gain (17 dB versus 16 dB), delivering superior performance margins without requiring circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the PD85035STR-E directly replace the PD85015STR-E in existing designs?

A: Yes. Both components share identical frequency (870 MHz), test voltage (13.6 V), rated voltage (40 V), output power (15 W), and PowerSO-10RF package configuration. The substitute part is electrically and mechanically compatible for direct substitution.

Q: What are the key differences between these two parts?

A: The PD85035STR-E provides higher current rating (8 A versus 5 A), higher test current (350 mA versus 150 mA), and higher gain (17 dB versus 16 dB). The PD85015STR-E is obsolete while the PD85035STR-E maintains active product status.

Q: Are there any compliance or certification differences?

A: No. Both components maintain identical RoHS3 compliance, REACH unaffected status, and MSL 3 (168 Hours) moisture sensitivity ratings. Regulatory and handling requirements are equivalent.

Q: Does the higher current rating of the PD85035STR-E affect circuit design?

A: The higher current rating and gain of the PD85035STR-E represent performance improvements that do not require circuit modifications. Existing designs operate within the electrical specifications of the substitute part.

Q: What is the packaging difference between these parts?

A: Both components use identical PowerSO-10RF packaging with exposed bottom pad and 2 straight leads. No PCB layout or assembly process changes are required.

Q: Why is the PD85015STR-E classified as obsolete?

A: The PD85015STR-E has reached end-of-life status. The PD85035STR-E serves as the active equivalent, providing superior performance characteristics while maintaining full compatibility with existing applications.
