Substitute Part Grouping Explanation

Substitute parts for the MPSH10-AP are grouped based on electrical parameter compatibility and application suitability. The primary substitution criteria are:

Critical Parameters for Substitution:

• Transistor Type: NPN (mandatory match)
• Voltage - Collector Emitter Breakdown (Max): 25V or higher
• Frequency - Transition: 650MHz or higher
• Power - Max: 350mW or higher
• DC Current Gain (hFE): 60 or higher at specified conditions
• Current - Collector (Ic) (Max): 50mA or higher
• Operating Temperature Range: Must include 150°C maximum

Substitution Categories:

Category 1: Through-Hole Direct Replacement The KSP10BU from Fairchild Semiconductor matches all critical electrical parameters and maintains through-hole TO-92-3 packaging, providing a direct form-factor replacement for the obsolete MPSH10-AP.

Category 2: Surface Mount Equivalents with Matching Voltage and Frequency The MMBTH10-4LT1G from onsemi provides equivalent voltage rating (25V) and exceeds frequency performance (800MHz), with surface mount SOT-23-3 packaging suitable for modern PCB designs.

Category 3: Higher Performance Surface Mount Options The MCH4015-TL-H, 2SC5087R(TE85L,F), and BFP196E6327HTSA1 offer enhanced frequency performance (10GHz, 8GHz, and 7.5GHz respectively) with increased power handling and current capacity, suitable for applications requiring higher performance margins.

Category 4: Ultra-High Frequency Specialized Devices The BFP843H6327XTSA1 and BFR840L3RHESDE6327XTSA1 are optimized for ultra-high frequency applications (125GHz and 75GHz respectively) with reduced voltage ratings, applicable only to designs with lower voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole Replacement: The KSP10BU from Fairchild Semiconductor is the primary recommendation for applications requiring through-hole mounting. This device maintains identical electrical specifications to the MPSH10-AP (25V, 650MHz, 350mW, 60 hFE) while offering active product status and RoHS3 compliance. The KSP10BU is available in high inventory quantities (124,035 pcs) and requires no circuit redesign.

For Surface Mount Migration with Voltage Compatibility: The MMBTH10-4LT1G from onsemi provides a surface mount alternative while maintaining the 25V voltage rating of the original MPSH10-AP. This device offers improved frequency performance (800MHz) and higher current gain (120 hFE), with ROHS3 compliance and REACH unaffected status. The SOT-23-3 package is suitable for modern PCB layouts.

For Enhanced Performance Applications: The MCH4015-TL-H from onsemi and BFP196E6327HTSA1 from Infineon Technologies are suitable for applications requiring higher frequency operation (10GHz and 7.5GHz respectively) and increased power handling. Both devices maintain 150°C maximum operating temperature and offer ROHS3 compliance. Note that MCH4015-TL-H operates at 12V maximum, requiring voltage derating in 25V applications.

For Ultra-High Frequency Specialized Applications: The BFP843H6327XTSA1 and BFR840L3RHESDE6327XTSA1 are applicable only to designs with reduced voltage requirements (2.25V and 2.6V respectively). These devices are not suitable as general replacements for the MPSH10-AP due to voltage incompatibility.

Compliance Considerations: All recommended substitute parts maintain RoHS compliance (RoHS3 or RoHS Compliant). The Infineon devices (BFP196E6327HTSA1, BFP843H6327XTSA1, BFR840L3RHESDE6327XTSA1) carry REACH Unaffected status. All parts are classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can the MMBTH10-4LT1G replace the MPSH10-AP in all applications? A: The MMBTH10-4LT1G maintains the 25V voltage rating and exceeds frequency performance (800MHz vs. 650MHz). However, it operates at reduced maximum power (225mW vs. 350mW) and requires surface mount PCB design. Verify power dissipation requirements in your specific application before substitution.

Q: What is the primary advantage of the KSP10BU over the MPSH10-AP? A: The KSP10BU provides identical electrical performance with active product status, eliminating obsolescence concerns. It maintains through-hole TO-92-3 packaging, allowing direct board-level replacement without design modification.

Q: Why do the MCH4015-TL-H and 2SC5087R operate at 12V instead of 25V? A: These devices are optimized for higher frequency operation (10GHz and 8GHz respectively) with different semiconductor designs. The reduced voltage rating reflects their specialized RF performance characteristics. They are suitable only for applications with 12V or lower voltage requirements.

Q: Are the BFP843H6327XTSA1 and BFR840L3RHESDE6327XTSA1 suitable replacements for the MPSH10-AP? A: These devices are not suitable as general replacements. Their maximum voltage ratings (2.25V and 2.6V respectively) are significantly lower than the MPSH10-AP (25V), making them applicable only to specialized low-voltage, ultra-high-frequency applications.

Q: What packaging considerations apply when switching from through-hole to surface mount? A: Surface mount substitutes (MMBTH10-4LT1G, MCH4015-TL-H, BFP196E6327HTSA1, BFP843H6327XTSA1, BFR840L3RHESDE6327XTSA1) require PCB redesign with appropriate land patterns, solder reflow processes, and thermal management considerations. Through-hole designs cannot directly accommodate surface mount packages without board layout modification.

Q: How do the DC current gain specifications compare across substitute parts? A: The MPSH10-AP specifies 60 hFE minimum at 4mA, 10V. The MMBTH10-4LT1G provides 120 hFE at the same conditions, offering improved gain. The MCH4015-TL-H maintains 60 hFE but at different conditions (50mA, 5V). Higher gain devices may require circuit biasing adjustments in sensitive applications.

Q: What is the operating temperature range compatibility? A: The MPSH10-AP operates from -55°C to 150°C. The KSP10BU and MMBTH10-4LT1G maintain this full range. The 2SC5087R operates to 125°C maximum, which may be limiting in high-temperature applications. All other substitutes operate to 150°C maximum.

Q: Are all substitute parts RoHS compliant? A: Yes. The KSP10BU is RoHS Compliant. The MMBTH10-4LT1G, MCH4015-TL-H, BFP196E6327HTSA1, BFP843H6327XTSA1, and BFR840L3RHESDE6327XTSA1 are all ROHS3 Compliant. All parts meet current environmental compliance requirements.
