PD55003 RF MOSFET LDMOS Equivalent & Substitute Parts

Part Overview

The PD55003 is an RF MOSFET LDMOS transistor manufactured by STMicroelectronics, designed for RF applications operating at 500MHz with 17dB gain and 3W output power. The device is rated for 12.5V test voltage and 40V rated voltage, housed in a PowerSO-10 package with exposed bottom pad.

The PD55003 is classified as obsolete. Locating equivalent and substitute parts is necessary to support ongoing production requirements, maintenance operations, and system redesigns where this component is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PD55003 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: 2.5A
• Current - Test: 50mA
• Power - Output: 3W
• Package / Case: PowerSO-10 Exposed Bottom Pad
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 3 (168 Hours)

Substitute parts must match all electrical specifications and package requirements. Packaging format (tube, tray, or reel) does not affect electrical compatibility but may impact procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

The PD55003-E is a direct electrical and mechanical equivalent to the PD55003. Both parts are manufactured by STMicroelectronics and share identical electrical specifications, package configuration, and regulatory compliance status.

Key Selection Factors:

Product Status: The PD55003-E carries Active product status, whereas the original PD55003 is Obsolete. Selection of the PD55003-E ensures access to current manufacturing and long-term availability for production and field replacement applications.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 export classification. No compliance barriers exist for substitution.

Packaging: The PD55003-E is supplied in Tube packaging format. Verify that tube packaging is compatible with your assembly and handling procedures. The electrical performance and pin configuration remain identical regardless of packaging format.

Moisture Sensitivity: Both parts carry MSL 3 (168 Hours) rating. Identical moisture handling and storage protocols apply to both components.

Frequently Asked Questions (FAQ)

Q: Can the PD55003-E replace the PD55003 in existing designs?

A: Yes. The PD55003-E is electrically and mechanically equivalent to the PD55003. All electrical parameters, package dimensions, and pin configurations are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between PD55003 and PD55003-E?

A: The primary difference is product status and packaging format. The PD55003 is Obsolete; the PD55003-E is Active. The PD55003-E is supplied in Tube packaging. All electrical specifications and package types (PowerSO-10 Exposed Bottom Pad) are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, and EAR99 export classification. No additional certifications or compliance barriers apply to the PD55003-E.

Q: Does packaging format affect electrical performance?

A: No. Tube packaging is a supply and handling format only. Electrical performance, thermal characteristics, and RF specifications are identical between packaging formats.

Q: What is the moisture sensitivity requirement for storage?

A: Both parts carry MSL 3 (168 Hours) rating. Components must be stored in controlled humidity environments and baked according to IPC-A-610 standards prior to reflow soldering if moisture absorption limits are exceeded.

Q: Is the PD55003-E suitable for new designs?

A: Yes. The PD55003-E is an Active product with current manufacturing support. It is suitable for both replacement of obsolete PD55003 components and incorporation into new RF circuit designs requiring 500MHz LDMOS transistors with 3W output power.
