Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD57006STR-E is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: STMicroelectronics
• Technology: LDMOS
• Frequency: 945 MHz
• Voltage - Test: 28 V
• Voltage - Rated: 65 V
• Package / Case: PowerSO-10RF with exposed bottom pad and straight leads
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

Allowable Parameter Variations: Substitute parts may exceed the original specifications in the following parameters without compromising circuit compatibility:

• Current Rating (Amps): Higher ratings are acceptable
• Current - Test: Higher test current values are acceptable
• Power - Output: Higher output power is acceptable
• Gain: Higher gain values are acceptable

The PD57018S-E meets all mandatory matching criteria and exceeds performance specifications in current rating, test current, output power, and gain, making it a direct substitute for the obsolete PD57006STR-E.

Engineering Selection Recommendations

The PD57018S-E is the direct substitute for the obsolete PD57006STR-E based on the following engineering criteria:

Product Status Alignment: The PD57018S-E holds active product status with STMicroelectronics, ensuring continued availability, technical support, and supply chain reliability. The PD57006STR-E is obsolete and no longer manufactured.

Regulatory and Compliance Alignment: Both devices maintain identical RoHS3 compliance, Moisture Sensitivity Level 3 (168 Hours), REACH unaffected status, and EAR99 ECCN classification. No additional compliance documentation or design modifications are required for substitution.

Functional Compatibility: The PD57018S-E operates at identical frequency (945 MHz), test voltage (28 V), and rated voltage (65 V). The package type (PowerSO-10RF with exposed bottom pad and straight leads) is mechanically and electrically compatible. The substitute device provides enhanced performance specifications: 2.5 A current rating versus 1 A, 18 W output power versus 6 W, and 16.5 dB gain versus 15 dB. These higher specifications do not introduce incompatibility and provide design margin for existing applications.

Supply Availability: The PD57018S-E is available in active inventory (1557 Pcs New Original In Stock) with tube packaging, supporting both prototype and production requirements.

Frequently Asked Questions (FAQ)

Q: Can the PD57018S-E be used as a direct replacement for the PD57006STR-E in existing designs?

A: Yes. The PD57018S-E is a direct substitute. Both devices operate at 945 MHz, 28 V test voltage, and 65 V rated voltage in identical PowerSO-10RF packages with exposed bottom pad and straight leads. The substitute provides higher current rating (2.5 A vs. 1 A), output power (18 W vs. 6 W), and gain (16.5 dB vs. 15 dB), which are compatible with existing circuit designs.

Q: Are there any package differences between the PD57006STR-E and PD57018S-E?

A: Both devices use PowerSO-10RF packages with exposed bottom pad and straight leads. The package designation for the PD57018S-E is listed as PowerSO-10, which is the same package family with identical pin configuration and thermal characteristics.

Q: What is the significance of the higher power output (18 W vs. 6 W) in the substitute part?

A: The higher power output of the PD57018S-E indicates improved efficiency and performance capability at the same operating frequency and voltage. This specification difference does not create incompatibility; it provides additional design margin and performance headroom for the application.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both the PD57006STR-E and PD57018S-E are classified as Moisture Sensitivity Level 3 (168 Hours), requiring identical handling, storage, and reflow procedures during assembly.

Q: Are there any regulatory or compliance differences between these parts?

A: No. Both devices are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. No additional compliance documentation is required for substitution.

Q: Why is the PD57006STR-E listed as obsolete?

A: The PD57006STR-E is no longer manufactured by STMicroelectronics. The PD57018S-E is the active product replacement that maintains functional compatibility while providing enhanced performance specifications.

Q: What is the difference between the test current (70 mA vs. 100 mA) specifications?

A: Test current represents the quiescent or bias current under specified test conditions. The higher test current of the PD57018S-E (100 mA) reflects the device's enhanced performance characteristics and does not affect substitution compatibility in RF power amplification applications.
