Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD55003STR-E is determined by equivalence across the following critical parameters:

Electrical Parameters:

• Technology: LDMOS
• Frequency: 500 MHz
• Gain: 17 dB
• Voltage - Test: 12.5 V
• Voltage - Rated: 40 V
• Current Rating: 2.5 A
• Current - Test: 50 mA
• Power - Output: 3 W

Mechanical & Environmental Parameters:

• Package / Case: PowerSO-10 Exposed Bottom Pad
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

Compliance & Regulatory:

• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8541.29.0095

The substitute part PD55003-E maintains identical electrical specifications and compliance certifications. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) with straight leads, while the substitute is supplied in Tube packaging. Both utilize the same PowerSO-10 case with exposed bottom pad and are manufactured by STMicroelectronics under the same base product number PD55003.

Parameter Comparison

Engineering Selection Recommendations

The PD55003-E is a direct electrical and mechanical equivalent to the PD55003STR-E. All critical electrical parameters, package specifications, and regulatory compliance certifications are identical between the two parts.

Product Status Consideration: The PD55003STR-E is classified as obsolete, while the PD55003-E is active. Selection of the PD55003-E provides access to an actively manufactured component from the same manufacturer, ensuring long-term availability and supply chain continuity.

Packaging Format Difference: The primary distinction between these parts is the supply format. The PD55003STR-E is supplied in Tape & Reel with straight leads, optimized for automated pick-and-place assembly. The PD55003-E is supplied in Tube packaging. This difference affects handling and assembly processes but does not impact electrical performance or PCB-level compatibility, as both utilize the identical PowerSO-10 case with exposed bottom pad.

Compliance & Regulatory Status: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications, ensuring regulatory equivalence for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Are the PD55003STR-E and PD55003-E electrically identical?

A: Yes. Both parts share identical electrical specifications including 500 MHz frequency, 17 dB gain, 12.5V test voltage, 2.5A current rating, and 3W output power. They are manufactured by STMicroelectronics under the same base product number PD55003.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The PD55003STR-E is supplied in Tape & Reel with straight leads, while the PD55003-E is supplied in Tube. Both use the PowerSO-10 case with exposed bottom pad. Additionally, the PD55003STR-E is obsolete while the PD55003-E is active.

Q: Can I use PD55003-E as a direct replacement for PD55003STR-E on a PCB?

A: Yes. Both parts use the identical PowerSO-10 package with exposed bottom pad, ensuring pin-for-pin and footprint compatibility on the PCB. The packaging format difference (Tape & Reel versus Tube) affects component handling and assembly logistics but not PCB-level installation.

Q: Does the Tube packaging affect performance or reliability?

A: No. Packaging format does not affect electrical performance, thermal characteristics, or reliability. Both formats provide equivalent moisture protection (MSL 3, 168 Hours) and maintain identical electrical specifications.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and share identical ECCN (EAR99) and HTSUS (8541.29.0095) classifications.

Q: Why is the PD55003STR-E marked as obsolete?

A: The PD55003STR-E is obsolete, indicating it is no longer in active production. The PD55003-E remains active and is the recommended source for new procurement and long-term supply continuity.

Q: Can I mix PD55003STR-E and PD55003-E in the same production batch?

A: Yes. Both parts are electrically and mechanically equivalent. However, packaging format differences may require separate handling procedures during assembly. Consult manufacturing and assembly documentation for specific process requirements.
