Substitute Part Grouping Explanation

Substitution of the PD54008 RF MOSFET LDMOS transistor is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Technology: LDMOS
• Frequency: 500 MHz
• Gain: 11.5 dB
• Voltage - Test: 7.5 V
• Voltage - Rated: 25 V
• Current Rating: 5 A
• Current - Test: 150 mA
• Power - Output: 8 W

Mechanical Parameters (Must Match):

• Package / Case: PowerSO-10 Exposed Bottom Pad
• Supplier Device Package: 10-PowerSO

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)
• REACH Status: REACH Unaffected

The substitute part PD54008-E maintains identical electrical and mechanical specifications while offering active product status and alternative packaging configuration (Tube).

Parameter Comparison

Engineering Selection Recommendations

PD54008-E is the direct equivalent substitute for the obsolete PD54008 RF MOSFET LDMOS transistor. The substitute part maintains complete electrical and mechanical parameter equivalence across all critical specifications including frequency, gain, voltage ratings, current ratings, and output power.

Product Status Consideration: The PD54008-E carries active product status, ensuring ongoing manufacturer support, availability, and compliance maintenance. The original PD54008 is classified as obsolete, which presents long-term sourcing risk.

Compliance Status: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level classification. No compliance degradation occurs with substitution.

Packaging Configuration: The PD54008-E is supplied in Tube packaging, whereas the original part packaging configuration is unspecified. Both parts utilize the identical PowerSO-10 Exposed Bottom Pad package case and 10-PowerSO supplier device package.

Inventory Availability: Current inventory levels support both parts, with PD54008-E showing 1057 pieces and PD54008 showing 1029 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can PD54008-E be used as a direct replacement for PD54008 in existing designs?

A: Yes. The PD54008-E maintains identical electrical specifications (frequency, gain, voltage, current, and power ratings) and mechanical specifications (PowerSO-10 package). No circuit redesign is required.

Q: What is the difference between PD54008 and PD54008-E?

A: The primary differences are product status and packaging configuration. PD54008-E is active product status with Tube packaging, while PD54008 is obsolete with unspecified packaging. All electrical and mechanical parameters are identical.

Q: Are there any compliance differences between the two parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 3, 168 Hours).

Q: Does the PowerSO-10 package remain the same for both parts?

A: Yes. Both PD54008 and PD54008-E use the PowerSO-10 Exposed Bottom Pad package case with 10-PowerSO supplier device package designation. PCB layout and thermal management considerations remain unchanged.

Q: Why should I transition from PD54008 to PD54008-E?

A: The PD54008 is classified as obsolete product status. Transitioning to PD54008-E ensures long-term component availability, ongoing manufacturer support, and compliance maintenance for future production runs and design revisions.

Q: Are the RF performance characteristics identical?

A: Yes. Both parts operate at 500 MHz with 11.5 dB gain and 8W output power. RF performance parameters are fully equivalent.
