MPSA10 Equivalent & Substitute Parts

Part Overview

The MPSA10 is an NPN bipolar junction transistor manufactured by onsemi, designed for general-purpose switching and amplification applications. This device features a maximum collector-emitter voltage of 40 V, collector current rating of 100 mA, and power dissipation of 625 mW in a Through Hole TO-92-3 package. The MPSA10 is classified as obsolete, necessitating identification of active alternative components that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPSA10 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Transistor type must be NPN
• Voltage - Collector Emitter Breakdown rating must be equal to or greater than 40 V
• Current - Collector (Ic) maximum rating must be equal to or greater than 100 mA
• Power dissipation must support 625 mW or greater

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Package must be TO-92-3 (TO-226-3 or TO-226AA equivalent)

The LP395Z/NOPB from Texas Instruments qualifies as a substitute based on matching transistor type (NPN), identical package configuration (TO-92-3 Through Hole), and compatible electrical ratings within the specified parameter range.

Parameter Comparison

Engineering Selection Recommendations

The LP395Z/NOPB from Texas Instruments is an active substitute for the obsolete MPSA10. Both devices share identical mechanical compatibility through the TO-92-3 Through Hole package configuration. The LP395Z/NOPB maintains NPN transistor type equivalence and operates within the electrical parameter envelope of the MPSA10 application space.

The LP395Z/NOPB carries RoHS3 compliance certification, whereas the MPSA10 status reflects its obsolete classification. Both components are REACH Unaffected and classified under EAR99 export control. The LP395Z/NOPB is currently in active production with documented inventory availability, providing supply chain continuity for applications previously designed around the MPSA10.

Frequently Asked Questions (FAQ)

Q: Can the LP395Z/NOPB directly replace the MPSA10 in existing circuit designs?

A: The LP395Z/NOPB shares the same TO-92-3 package pinout and NPN transistor configuration as the MPSA10, enabling direct mechanical and electrical substitution within the specified parameter constraints. The 36 V collector-emitter breakdown rating of the LP395Z/NOPB is lower than the MPSA10's 40 V rating; applications operating at voltages between 36 V and 40 V require circuit evaluation.

Q: What are the key differences between the MPSA10 and LP395Z/NOPB?

A: The primary differences are product status (MPSA10 is obsolete; LP395Z/NOPB is active), maximum operating temperature (150°C versus 125°C), and collector-emitter breakdown voltage (40 V versus 36 V). The LP395Z/NOPB carries RoHS3 compliance, whereas the MPSA10 predates this certification requirement.

Q: Are there any package compatibility concerns when substituting these parts?

A: Both the MPSA10 and LP395Z/NOPB use the TO-92-3 Through Hole package with identical pinout configuration. No package-related modifications are required for substitution.

Q: What compliance certifications apply to the LP395Z/NOPB?

A: The LP395Z/NOPB is RoHS3 compliant and REACH Unaffected. Both the MPSA10 and LP395Z/NOPB are classified under EAR99 export control.

Q: Is the LP395Z/NOPB suitable for high-temperature applications?

A: The LP395Z/NOPB operates to a maximum junction temperature of 125°C, which is 25°C lower than the MPSA10's 150°C maximum. Applications requiring operation above 125°C require alternative component selection.
