Substitute Part Grouping Explanation

Substitution of the PD55008 RF MOSFET LDMOS is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Technology: LDMOS
• Frequency: 500MHz
• Gain: 17dB
• Voltage - Test: 12.5V
• Voltage - Rated: 40V
• Current Rating: 4A
• Current - Test: 150mA
• Power - Output: 8W
• Package / Case: PowerSO-10 Exposed Bottom Pad
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

Parts meeting all these parameters are classified as direct equivalents and may be substituted without circuit redesign or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

PD55008-E is a direct electrical and mechanical equivalent to the PD55008. All critical electrical parameters, package specifications, and compliance certifications are identical.

The primary distinction is product status: the PD55008 is obsolete, while the PD55008-E is active. The PD55008-E maintains ROHS3 compliance and identical moisture sensitivity specifications, ensuring compatibility with existing design requirements and supply chain continuity.

Selection of PD55008-E is appropriate for new production, field replacements, and design updates where the PD55008 is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can PD55008-E be used as a direct replacement for PD55008 in existing designs?

A: Yes. The PD55008-E is electrically and mechanically equivalent to the PD55008 across all specified parameters, including frequency, gain, voltage ratings, current ratings, power output, and package configuration. No circuit modifications are required.

Q: What is the difference between PD55008 and PD55008-E?

A: The PD55008 is classified as obsolete, while the PD55008-E is active. Both devices share identical electrical specifications and package requirements. The PD55008-E is the current production variant available through active distribution.

Q: Are there packaging differences between PD55008 and PD55008-E?

A: Both devices use the PowerSO-10 package with exposed bottom pad. The PD55008-E is supplied in tube packaging, while the original PD55008 packaging format is not specified in available data. The package footprint and pin configuration are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PD55008 and PD55008-E are ROHS3 compliant and REACH unaffected. Both carry identical moisture sensitivity level ratings of 3 (168 Hours). Compliance certifications are equivalent.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: LDMOS technology, 500MHz frequency, 17dB gain, 12.5V test voltage, 40V rated voltage, 4A current rating, 150mA test current, 8W output power, PowerSO-10 package with exposed bottom pad, and ROHS3 compliance status.
