SD2932 RF MOSFET 50V Equivalent & Substitute Parts

Part Overview

The SD2932 is an N-Channel RF MOSFET manufactured by STMicroelectronics, designed for RF applications operating at 175MHz with 16dB gain and 300W output power capability. The device is rated for 50V test voltage and 125V rated voltage, with a 500mA test current and 40A current rating in the M244 package.

The SD2932 carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this RF MOSFET topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SD2932 are classified based on alignment with the following critical parameters:

Direct Substitutes maintain identical electrical specifications across frequency, gain, test voltage, rated voltage, current rating, test current, and output power. These parts operate within the same functional envelope and package classification.

Similar Substitutes share core RF performance characteristics (frequency, gain, output power, test voltage, and test current) but may differ in package type, configuration topology, or rated voltage specifications. These parts require design review to confirm mechanical and electrical compatibility within the target application.

The substitution logic prioritizes:

• Frequency alignment (175MHz)
• Gain specification (16dB)
• Output power capability (300W)
• Test voltage compatibility (50V)
• Test current specification (500mA)
• Package and case type

Parameter Comparison

Engineering Selection Recommendations

SD2932W (STMicroelectronics) is the primary direct substitute for the obsolete SD2932. Both parts are manufactured by STMicroelectronics and share identical electrical specifications across all critical RF parameters: 175MHz frequency, 16dB gain, 50V test voltage, 125V rated voltage, 40A current rating, 500mA test current, and 300W output power. The SD2932W is in Active product status, ensuring ongoing availability and supply chain support. Both parts utilize the M244 package and maintain ROHS3 compliance and unlimited MSL rating. The SD2932W is supplied in Tube packaging, whereas the original SD2932 packaging is not specified. This part is suitable for direct replacement in existing designs without modification.

VRF151G (Microchip Technology) is a similar substitute that shares RF performance characteristics (175MHz, 16dB gain, 300W output power, 50V test voltage, 500mA test current) but differs in critical specifications. The VRF151G features a dual N-Channel common source configuration rather than single N-Channel, a 170V rated voltage (versus 125V), a 1mA current rating (versus 40A), and a 4-SMD package (versus M244). The VRF151G is in Active product status. Due to configuration differences, package type variation, and current rating disparity, the VRF151G requires design-level evaluation for compatibility with the target application circuit topology and PCB layout.

Both substitute parts maintain ROHS3 compliance, unlimited MSL rating, and REACH Unaffected status, consistent with the original SD2932 regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can SD2932W be used as a direct replacement for SD2932?

A: Yes. The SD2932W is a direct substitute manufactured by STMicroelectronics with identical electrical specifications: 175MHz frequency, 16dB gain, 50V test voltage, 125V rated voltage, 40A current rating, 500mA test current, and 300W output power. Both parts use the M244 package. The SD2932W is in Active product status, providing supply continuity for the obsolete SD2932.

Q: What are the key differences between SD2932 and VRF151G?

A: The VRF151G differs in three critical areas: (1) Configuration—VRF151G is a dual N-Channel common source device versus single N-Channel for SD2932; (2) Current Rating—VRF151G is rated at 1mA versus 40A for SD2932; (3) Package—VRF151G uses 4-SMD versus M244 for SD2932. The VRF151G also has a higher rated voltage of 170V compared to 125V. These differences require circuit-level compatibility assessment.

Q: Are all substitute parts RoHS compliant?

A: Yes. Both SD2932W and VRF151G are ROHS3 compliant, matching the compliance status of the original SD2932. All three parts are REACH Unaffected and carry unlimited MSL rating (Level 1).

Q: What packaging formats are available for these parts?

A: SD2932W is supplied in Tube packaging. VRF151G is supplied in Box packaging. The original SD2932 packaging format is not specified in the available data.

Q: Can VRF151G be used in applications designed for SD2932?

A: VRF151G shares RF performance parameters (175MHz, 16dB gain, 300W output power) but differs significantly in device configuration (dual N-Channel common source), current rating (1mA versus 40A), and package type (4-SMD versus M244). Application compatibility requires detailed circuit analysis and PCB layout evaluation.

Q: What is the inventory status of substitute parts?

A: SD2932W has 2200 pieces in stock (Active status). VRF151G has 2100 pieces in stock (Active status). The original SD2932 has 3100 pieces in stock but carries Obsolete product status.
