PUMB24,115 Equivalent & Substitute Parts

Part Overview

The PUMB24,115 is a pre-biased dual PNP bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. in a 6-TSSOP surface mount package. This component integrates two PNP transistors with internal biasing resistors, designed for switching and amplification applications requiring 50V collector-emitter breakdown voltage and 20mA maximum collector current. The part maintains Active product status and is AEC-Q100 qualified for automotive applications. Equivalent and substitute parts are identified to support design flexibility, inventory management, and supply chain continuity for applications where the PUMB24,115 specifications are met or exceeded by alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PUMB24,115 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Transistor configuration: Dual PNP pre-biased topology
• Voltage rating: Collector-emitter breakdown voltage of 50V or greater
• Base and emitter-base resistor values: 100kOhms each
• DC current gain (hFE): Minimum 80 at specified operating conditions
• Package compatibility: 6-TSSOP, SC-88, or SOT-363 surface mount packages

Mechanical Compatibility Criteria:

• Surface mount packaging in 6-pin configuration
• Tape & Reel (TR) availability for automated assembly

Compliance Criteria:

• RoHS3 compliance
• Moisture sensitivity level MSL 1 (Unlimited)
• REACH unaffected status

The MUN5136DW1T1G manufactured by onsemi meets all electrical and mechanical substitution criteria. While the MUN5136DW1T1G exhibits higher maximum collector current (100mA versus 20mA) and lower maximum power dissipation (250mW versus 300mW), these parameters remain within acceptable substitution boundaries for applications designed for the PUMB24,115 specification envelope. The identical internal resistor configuration, voltage rating, and package format ensure functional interchangeability.

Engineering Selection Recommendations

PUMB24,115 (Nexperia USA Inc.):

• Primary selection for applications requiring AEC-Q100 automotive qualification
• Specified maximum collector current of 20mA and 300mW power dissipation
• Active product status with established supply chain
• Recommended for designs with automotive-grade component requirements

MUN5136DW1T1G (onsemi):

• Functionally equivalent substitute with identical electrical configuration
• Higher current capability (100mA) and lower collector cutoff current (500nA) provide design margin
• Active product status with independent supply availability
• Suitable for applications where PUMB24,115 specifications are met or exceeded
• RoHS3 and REACH compliance maintained
• MSL 1 rating ensures compatibility with standard moisture control procedures

Both parts maintain Active product status and full regulatory compliance. Selection between these components is determined by supply availability, cost considerations, and specific application current requirements within the 20mA to 100mA operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the MUN5136DW1T1G directly replace the PUMB24,115 in existing designs?

A: Yes. Both components share identical transistor topology (dual PNP pre-biased), voltage rating (50V), internal resistor configuration (100kOhms base and emitter-base), and surface mount package format (6-TSSOP/SC-88/SOT-363). The MUN5136DW1T1G meets or exceeds all electrical specifications of the PUMB24,115.

Q: What is the significance of the higher collector current rating on the MUN5136DW1T1G?

A: The MUN5136DW1T1G maximum collector current of 100mA exceeds the PUMB24,115 specification of 20mA. This provides additional design margin for applications operating near the upper current limit. Applications designed for 20mA operation remain fully compatible with the substitute part.

Q: Are there package compatibility concerns between these parts?

A: No. Both the PUMB24,115 and MUN5136DW1T1G are available in 6-TSSOP, SC-88, and SOT-363 surface mount packages. Footprint and pin configuration are identical, enabling direct PCB layout compatibility.

Q: Do both parts meet automotive qualification requirements?

A: The PUMB24,115 carries AEC-Q100 automotive qualification. The MUN5136DW1T1G does not specify AEC-Q100 qualification in the provided data. Applications requiring explicit automotive qualification should specify the PUMB24,115.

Q: What is the impact of the lower power dissipation rating on the MUN5136DW1T1G?

A: The MUN5136DW1T1G maximum power dissipation is 250mW compared to 300mW for the PUMB24,115. Applications operating below 250mW are unaffected. Designs approaching or exceeding 250mW should be evaluated against actual operating conditions to ensure thermal compliance.

Q: Are moisture sensitivity and RoHS compliance identical between these parts?

A: Yes. Both components are MSL 1 (Unlimited) rated and ROHS3 compliant, ensuring equivalent handling and environmental compliance requirements.

Q: How do the saturation voltage characteristics compare?

A: The PUMB24,115 specifies 150mV maximum saturation voltage at 250µA base current and 5mA collector current. The MUN5136DW1T1G specifies 250mV maximum at 300µA base current and 10mA collector current. Both values are within acceptable switching performance ranges for pre-biased transistor applications.
