MPSA13_D26Z Equivalent & Substitute Parts

Part Overview

The MPSA13_D26Z is an NPN Darlington bipolar junction transistor manufactured by onsemi, designed for general-purpose switching and amplification applications. This device features a maximum collector current of 1.2 A, collector-emitter breakdown voltage of 30 V, and maximum power dissipation of 625 mW in a Through Hole TO-92-3 package. The MPSA13_D26Z is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPSA13_D26Z is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Transistor Type: NPN - Darlington configuration
• Collector-Emitter Breakdown Voltage: 30 V (maximum)
• Vce Saturation: 1.5 V @ 100µA, 100mA
• DC Current Gain (hFE): 10000 minimum @ 100mA, 5V
• Transition Frequency: 125 MHz
• Maximum Power Dissipation: 625 mW
• Package Type: TO-92-3 Through Hole
• Mounting Type: Through Hole

Allowable Variation Parameter:

• Maximum Collector Current (Ic): The substitute part may operate at a lower maximum current rating provided all other electrical characteristics remain equivalent. A lower Ic rating does not compromise functionality in applications where the required current is within the substitute's specification.

The KSP13TA meets all mandatory matching parameters and is therefore qualified as a direct substitute, despite its lower maximum collector current rating of 500 mA compared to the MPSA13_D26Z specification of 1.2 A.

Parameter Comparison

Engineering Selection Recommendations

KSP13TA as Primary Substitute:

The KSP13TA is qualified as a direct substitute for the MPSA13_D26Z based on electrical parameter equivalence and package compatibility. The KSP13TA holds Active product status, ensuring long-term availability and supply chain continuity compared to the obsolete MPSA13_D26Z.

Compliance and Certification:

The KSP13TA carries RoHS3 compliance certification, whereas the MPSA13_D26Z compliance status is not specified in the provided data. Both parts are REACH Unaffected and classified under ECCN EAR99. The KSP13TA's active status and documented compliance certifications provide superior support for new designs and regulatory requirements.

Current Rating Consideration:

Applications requiring collector currents exceeding 500 mA must retain the MPSA13_D26Z or identify alternative parts with higher current ratings. For applications operating within the 500 mA maximum specification of the KSP13TA, the substitute provides full functional equivalence.

Temperature Range Consideration:

The MPSA13_D26Z specifies an operating temperature range of -55°C to 150°C. The KSP13TA specification provided indicates operation up to 150°C. Applications requiring operation below -55°C must verify the KSP13TA's lower temperature limit through the manufacturer's complete datasheet.

Frequently Asked Questions (FAQ)

Q: Can the KSP13TA replace the MPSA13_D26Z in all applications?

A: The KSP13TA is electrically equivalent to the MPSA13_D26Z for all parameters except maximum collector current and operating temperature range. Substitution is valid only when the application's required collector current does not exceed 500 mA and the operating temperature range requirement does not extend below -55°C.

Q: What is the primary difference between these two parts?

A: The KSP13TA has a maximum collector current rating of 500 mA compared to the MPSA13_D26Z rating of 1.2 A. All other electrical characteristics, including voltage ratings, gain, frequency response, and power dissipation, are identical.

Q: Why is the MPSA13_D26Z obsolete?

A: The MPSA13_D26Z is classified as obsolete by the manufacturer. The KSP13TA, with Active product status, represents the current equivalent offering for this device family.

Q: Are the packages physically identical?

A: Yes. Both the MPSA13_D26Z and KSP13TA use the TO-92-3 (TO-226AA) Through Hole package with formed leads. Physical footprint and pin configuration are identical, allowing direct board-level substitution.

Q: What compliance certifications apply to the KSP13TA?

A: The KSP13TA is RoHS3 compliant, REACH Unaffected, and classified under ECCN EAR99. These certifications support use in regulated applications and export-controlled environments.

Q: Can I use the MPSA13_D26Z in place of the KSP13TA?

A: The MPSA13_D26Z is electrically equivalent to the KSP13TA and can be used as a substitute where inventory exists. However, the MPSA13_D26Z's obsolete status makes it unsuitable for new designs or long-term procurement planning.

Q: What should I verify before substituting these parts?

A: Verify that the application's maximum required collector current does not exceed 500 mA and that the operating temperature range requirement is compatible with the substitute part's specification. Confirm that the circuit design does not depend on the higher current capability of the MPSA13_D26Z.
