Substitute Part Grouping Explanation

Substitution of the PD57030 RF MOSFET LDMOS transistor is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Technology: LDMOS
• Frequency: 945 MHz
• Voltage - Test: 28 V
• Voltage - Rated: 65 V
• Current Rating: 4 A
• Current - Test: 50 mA
• Power - Output: 30 W
• Gain: 14 dB
• Package / Case: PowerSO-10 Exposed Bottom Pad
• Supplier Device Package: 10-PowerSO

The substitute part PD57030-E maintains identical electrical specifications and mechanical packaging. The primary distinction is product status: PD57030-E is active production, whereas PD57030 is obsolete. Both parts share the same base product number (PD57030) and are manufactured by STMicroelectronics.

Engineering Selection Recommendations

PD57030-E is the direct equivalent substitute for the obsolete PD57030 RF MOSFET LDMOS transistor. Selection of PD57030-E is based on the following factors:

Product Status: PD57030-E maintains active production status with STMicroelectronics, ensuring ongoing availability and manufacturing support. The PD57030 is obsolete and no longer in production.

Electrical Equivalence: All electrical parameters are identical between PD57030 and PD57030-E, including frequency (945 MHz), test voltage (28 V), rated voltage (65 V), current rating (4 A), output power (30 W), and gain (14 dB).

Mechanical Compatibility: Both parts use the PowerSO-10 package with exposed bottom pad, ensuring direct pin-for-pin and thermal interface compatibility in existing circuit designs.

Regulatory Compliance: PD57030-E maintains ROHS3 compliance, REACH unaffected status, and EAR99 export classification, matching the compliance profile of the original part.

Moisture Sensitivity: Both parts carry MSL 3 (168 Hours) rating, requiring identical handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can PD57030-E be used as a direct replacement for PD57030 in existing designs?

A: Yes. PD57030-E is electrically and mechanically equivalent to PD57030. All electrical parameters, package configuration, and pin assignments are identical. Direct substitution is supported without circuit modification.

Q: What is the primary reason to transition from PD57030 to PD57030-E?

A: PD57030 is classified as obsolete and is no longer in active production. PD57030-E is the active production equivalent, ensuring supply chain continuity and access to current manufacturing support from STMicroelectronics.

Q: Are there differences in packaging between PD57030 and PD57030-E?

A: Both parts use the PowerSO-10 package with exposed bottom pad. The primary packaging difference is that PD57030-E is supplied in tube packaging, whereas PD57030 packaging format is not specified in the product data.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both PD57030 and PD57030-E are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level (MSL 3, 168 Hours) is identical for both parts.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching technology (LDMOS), frequency (945 MHz), test voltage (28 V), rated voltage (65 V), current rating (4 A), output power (30 W), and gain (14 dB). PD57030-E matches all these parameters with PD57030.

Q: Is the PowerSO-10 package with exposed bottom pad critical for thermal performance?

A: The exposed bottom pad is a thermal interface feature of the PowerSO-10 package. Both PD57030 and PD57030-E use this package configuration, ensuring equivalent thermal characteristics in circuit applications.
