Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD55003S is determined by strict equivalence across the following electrical and mechanical parameters:

• Technology: LDMOS (Laterally Diffused Metal Oxide Semiconductor)
• Frequency: 500MHz operational frequency
• Gain: 17dB
• Voltage - Test: 12.5V
• Voltage - Rated: 40V
• Current Rating: 2.5A
• Current - Test: 50mA
• Power - Output: 3W
• Package / Case: PowerSO-10 Exposed Bottom Pad
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

Substitute parts must maintain identical electrical performance characteristics and package compatibility to ensure functional equivalence in RF MOSFET applications.

Parameter Comparison

Engineering Selection Recommendations

The PD55003S-E is a direct substitute for the PD55003S. Both devices are manufactured by STMicroelectronics and maintain identical electrical specifications across all RF MOSFET parameters including frequency, gain, voltage ratings, current ratings, and output power.

The primary distinction between these parts is product status: the PD55003S is classified as Obsolete, while the PD55003S-E maintains Active status. The PD55003S-E is the recommended selection for new designs and ongoing production requirements due to its active product lifecycle and continued manufacturer support.

Both parts satisfy ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring environmental and hazardous substance restrictions. Moisture sensitivity level remains consistent at MSL 3 (168 Hours) for both devices.

The supplier device package designation differs between the two parts (10-PowerSO versus PowerSO-10RF with Straight Lead), but both maintain the PowerSO-10 Exposed Bottom Pad case configuration, ensuring mechanical and thermal compatibility in PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the PD55003S-E be used as a direct replacement for the PD55003S in existing designs?

A: Yes. The PD55003S-E is electrically and mechanically equivalent to the PD55003S. All RF MOSFET parameters including frequency, gain, voltage ratings, current ratings, and output power are identical. Both devices use the PowerSO-10 Exposed Bottom Pad package configuration.

Q: What is the difference between the 10-PowerSO and PowerSO-10RF (Straight Lead) package designations?

A: Both designations refer to the same PowerSO-10 Exposed Bottom Pad case configuration. The supplier device package designation reflects packaging and lead configuration details provided by the manufacturer. The mechanical and electrical interface remains consistent for PCB integration.

Q: Why is the PD55003S marked as Obsolete?

A: The PD55003S has reached end-of-life status in the manufacturer's product portfolio. The PD55003S-E, with Active product status, represents the current production equivalent and is the recommended selection for new applications and ongoing production support.

Q: Are there any compliance or regulatory differences between the PD55003S and PD55003S-E?

A: No. Both devices maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 ECCN classification. Moisture sensitivity level is MSL 3 (168 Hours) for both parts.

Q: What are the key electrical parameters that define substitution for this RF MOSFET?

A: Substitution is determined by equivalence across technology (LDMOS), frequency (500MHz), gain (17dB), test voltage (12.5V), rated voltage (40V), current rating (2.5A), test current (50mA), and output power (3W). Package configuration (PowerSO-10 Exposed Bottom Pad) and compliance certifications must also match.
