MPSH10-BP Equivalent & Substitute Parts

Part Overview

The MPSH10-BP is an RF transistor manufactured by Micro Commercial Co, classified as an NPN bipolar junction transistor (BJT) in a through-hole TO-92 package. This device is rated for 25V collector-emitter breakdown voltage, 50mA maximum collector current, and 650MHz transition frequency with 350mW maximum power dissipation. The MPSH10-BP is designated as obsolete product status, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPSH10-BP requires identification of NPN RF transistors that maintain electrical compatibility within the specified parameter envelope. The primary substitution criteria are:

Mandatory Compatibility Parameters:

• Transistor Type: NPN
• Voltage - Collector Emitter Breakdown (Max): Must equal or exceed 25V
• Current - Collector (Ic) (Max): Must equal or exceed 50mA
• Frequency - Transition: Must equal or exceed 650MHz
• Power - Max: Must equal or exceed 350mW
• DC Current Gain (hFE): Minimum 60 at specified operating point
• Operating Temperature Range: Must encompass -55°C to 150°C

The substitute parts identified are surface-mount RF transistors manufactured by Infineon Technologies with active product status. While these alternatives employ different package technologies (SOT-343 and SOT-23 surface-mount packages versus the through-hole TO-92 package of the original), they satisfy the electrical parameter requirements for RF applications. All substitute parts exceed the voltage, current, frequency, and power specifications of the MPSH10-BP and maintain NPN transistor topology.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MPSH10-BP is classified as obsolete, while all four identified substitute parts maintain active product status with Infineon Technologies. Active status ensures continued manufacturing availability, technical support, and supply chain reliability for production requirements.

Compliance and Certification: All substitute parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), matching the environmental and handling compliance profile of the original MPSH10-BP. All parts are classified under ECCN EAR99 and HTSUS 8541.21.0075, maintaining regulatory consistency.

Electrical Parameter Sufficiency: All four substitute parts exceed the minimum electrical requirements established by the MPSH10-BP specifications. Each substitute provides equal or greater voltage rating, current capacity, frequency capability, and power dissipation rating. DC current gain specifications are met or exceeded across all alternatives.

Package Technology Transition: The substitute parts employ surface-mount package technologies (SOT-343 and SOT-23) rather than the through-hole TO-92 package of the original device. This transition requires circuit board redesign and assembly process modification. BFR35APE6327HTSA1 offers the closest voltage rating (15V) to the original 25V specification, while BFP650H6327XTSA1 provides the highest frequency capability (37GHz) for advanced RF applications.

Frequently Asked Questions (FAQ)

Q: Can the MPSH10-BP be directly replaced with any of these substitute parts without circuit modification?

A: Direct pin-for-pin replacement is not possible due to package technology differences. The MPSH10-BP uses a through-hole TO-92 package, while all substitute parts employ surface-mount packages (SOT-343 or SOT-23). Circuit board layout and assembly processes require modification to accommodate surface-mount technology.

Q: Which substitute part most closely matches the original MPSH10-BP voltage specification?

A: The BFR35APE6327HTSA1 provides the closest voltage rating at 15V, compared to the original 25V specification. However, this part still exceeds the minimum voltage requirement for most RF applications operating below 15V. For applications requiring the full 25V rating, none of the substitute parts maintain this specification; alternative sourcing may be necessary.

Q: Are all substitute parts suitable for the same frequency range as the MPSH10-BP?

A: All substitute parts exceed the 650MHz transition frequency of the MPSH10-BP. The BFP650H6327XTSA1 operates at 37GHz, BFP450H6433XTMA1 at 24GHz, BFP196WH6327XTSA1 at 7.5GHz, and BFR35APE6327HTSA1 at 5GHz. Selection depends on the specific frequency requirements of the application.

Q: What is the impact of switching from through-hole to surface-mount packaging?

A: Surface-mount packages reduce board space requirements and enable automated assembly processes. However, they require different soldering techniques (reflow soldering versus wave soldering), modified circuit board design with surface-mount pads, and updated assembly procedures. Thermal management characteristics may also differ due to package geometry.

Q: Do all substitute parts maintain the same operating temperature range?

A: The substitute parts specify a maximum junction temperature of 150°C, matching the upper limit of the MPSH10-BP. However, the substitute parts do not specify a minimum operating temperature. The MPSH10-BP specifies -55°C minimum. Applications requiring operation below 0°C should verify substitute part performance at the required minimum temperature.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: All parts are RoHS compliant and carry identical ECCN and HTSUS classifications. The original MPSH10-BP is RoHS compliant, while substitute parts are ROHS3 compliant, representing an updated compliance standard. All parts maintain MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Which substitute part provides the best current handling capability?

A: The BFP650H6327XTSA1 and BFP196WH6327XTSA1 both support 150mA maximum collector current, compared to 50mA for the original MPSH10-BP. The BFP450H6433XTMA1 supports 100mA, and the BFR35APE6327HTSA1 supports 45mA. Selection should match the specific current requirements of the application.
