Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPSW13RLRAG is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Transistor Type: NPN - Darlington topology
• Voltage - Collector Emitter Breakdown (Max): 30 V minimum
• DC Current Gain (hFE): 10000 @ 100mA, 5V minimum
• Vce Saturation: 1.5V @ 100µA, 100mA maximum
• Frequency - Transition: 125 MHz minimum

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole
• Package / Case: TO-92-3 (TO-226 series)

Operational Compatibility Requirements:

• Operating Temperature Range: Support for -55°C to 150°C minimum

The KSP13TA meets all electrical and mechanical compatibility criteria. While the KSP13TA exhibits a reduced maximum collector current rating (500 mA versus 1 A), it maintains identical voltage, gain, saturation, and frequency specifications. This reduced current rating establishes the KSP13TA as a suitable substitute for applications operating within its 500 mA current envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: KSP13TA

The KSP13TA is the recommended substitute for the obsolete MPSW13RLRAG. Both components are manufactured by onsemi and maintain identical electrical specifications across voltage, gain, saturation, and frequency parameters. The KSP13TA is classified as Active product status, ensuring ongoing availability and supply chain continuity.

The KSP13TA carries RoHS3 compliance certification, providing enhanced environmental and regulatory alignment compared to the MPSW13RLRAG. Both devices maintain REACH Unaffected status and identical ECCN classification (EAR99).

Current Rating Consideration:

The KSP13TA maximum collector current rating is 500 mA, compared to 1 A for the MPSW13RLRAG. Selection of the KSP13TA is appropriate for applications where collector current does not exceed 500 mA. Applications requiring sustained collector currents above 500 mA require evaluation of alternative component families outside the provided substitute list.

Thermal and Packaging Compatibility:

Both devices operate across the -55°C to 150°C temperature range and utilize identical TO-92-3 Through Hole packaging. Pin configuration and mechanical footprint are directly compatible, enabling direct board-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the KSP13TA directly replace the MPSW13RLRAG in all applications?

A: The KSP13TA is electrically and mechanically compatible with the MPSW13RLRAG for applications where collector current remains at or below 500 mA. The KSP13TA maximum collector current rating (500 mA) is lower than the MPSW13RLRAG (1 A). Applications requiring collector currents exceeding 500 mA require alternative component selection.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Transistor Type (NPN - Darlington), (2) Voltage - Collector Emitter Breakdown (30 V minimum), (3) DC Current Gain (10000 @ 100mA, 5V), (4) Vce Saturation (1.5V @ 100µA, 100mA), and (5) Frequency - Transition (125 MHz). The KSP13TA meets all these criteria.

Q: Are the TO-92-3 packages of both devices mechanically identical?

A: Both the MPSW13RLRAG and KSP13TA utilize TO-92-3 (TO-226 series) Through Hole packaging with formed leads. The mechanical footprint and pin configuration are directly compatible, permitting direct board-level substitution without PCB modification.

Q: What is the difference in power dissipation capability between these devices?

A: The MPSW13RLRAG is rated for 1 W maximum power dissipation, while the KSP13TA is rated for 625 mW. This difference reflects the reduced maximum collector current rating of the KSP13TA. Applications operating within the KSP13TA current and power limits experience no functional difference.

Q: Does the KSP13TA offer improved regulatory compliance?

A: The KSP13TA carries RoHS3 compliance certification. Both devices maintain REACH Unaffected status and identical ECCN classification (EAR99). The KSP13TA provides enhanced environmental compliance alignment for new designs and production applications.

Q: What is the product status difference between these components?

A: The MPSW13RLRAG is classified as Obsolete, indicating discontinued manufacturing and limited future availability. The KSP13TA is classified as Active, ensuring ongoing production, supply chain availability, and long-term component sourcing stability.
