Key Parameters

Substitute Part Grouping Explanation

Substitution of the PMPB24EPX is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) rating must equal or exceed 30V
• Continuous drain current (Id) must meet or exceed 6.4A at 25°C
• On-resistance (Rds On) must not exceed the maximum specified value to ensure thermal performance equivalence
• Gate threshold voltage (Vgs(th)) must remain within acceptable switching characteristics
• Gate charge (Qg) and input capacitance (Ciss) must be compatible with existing gate drive circuitry
• Operating temperature range must encompass -55°C to 150°C

Mechanical Compatibility Criteria:

• Package type must be 6-UDFN Exposed Pad for PCB layout compatibility
• Surface mount mounting type is required
• Pin configuration must match the DFN2020 footprint family

Compliance Criteria:

• RoHS3 compliance is mandatory
• REACH Unaffected status is required

The PMPB17EPX meets all electrical and mechanical substitution criteria for the PMPB24EPX.

Parameter Comparison

Engineering Selection Recommendations

The PMPB17EPX is a direct substitute for the PMPB24EPX based on the following engineering criteria:

Electrical Performance: The PMPB17EPX exceeds the electrical specifications of the PMPB24EPX. It provides higher continuous drain current (7.7A versus 6.4A), lower on-resistance (21 mOhm versus 28 mOhm), and maintains identical gate threshold voltage characteristics. These improvements ensure equivalent or superior performance in existing circuit designs.

Package and Mechanical Compatibility: Both devices utilize the 6-UDFN Exposed Pad surface mount package. The DFN2020 footprint family ensures PCB layout compatibility without requiring design modifications.

Compliance and Regulatory Status: Both parts are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement and deployment.

Product Availability: The PMPB24EPX is classified as obsolete, while the PMPB17EPX maintains active product status. This transition ensures long-term supply chain continuity and supports ongoing production schedules.

Moisture Sensitivity Consideration: The PMPB24EPX carries MSL 3 (168 Hours), while the PMPB17EPX carries MSL 1 (Unlimited). The substitute part offers improved moisture handling characteristics, reducing storage and handling constraints.

Frequently Asked Questions (FAQ)

Q: Can the PMPB17EPX directly replace the PMPB24EPX in existing designs without circuit modifications?

A: Yes. The PMPB17EPX is electrically and mechanically compatible with the PMPB24EPX. Both devices share identical Vdss (30V), Vgs(th) (2.5V @ 250µA), and Vgs(Max) (±20V) specifications. The substitute part provides higher current capability and lower on-resistance, making it suitable for direct substitution in existing PCB layouts and gate drive circuits.

Q: What are the key electrical differences between these two parts?

A: The PMPB17EPX provides higher continuous drain current (7.7A versus 6.4A) and lower on-resistance (21 mOhm versus 28 mOhm). Gate charge and input capacitance are higher in the substitute part (47 nC and 1570 pF respectively, versus 28 nC and 1069 pF). These differences result in improved current handling and reduced conduction losses, with slightly increased gate drive requirements.

Q: Are there any package differences between the PMPB24EPX and PMPB17EPX?

A: Both parts use the 6-UDFN Exposed Pad surface mount package. The supplier device packages are designated DFN2020MD-6 (PMPB24EPX) and DFN2020M-6 (PMPB17EPX). These designations reflect minor manufacturing variations within the DFN2020 footprint family. PCB layout compatibility is maintained.

Q: What is the significance of the MSL rating difference?

A: The PMPB24EPX carries MSL 3 (168 Hours), requiring controlled moisture exposure during storage and handling. The PMPB17EPX carries MSL 1 (Unlimited), eliminating moisture sensitivity constraints. This improvement simplifies inventory management and reduces handling requirements for the substitute part.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the PMPB24EPX and PMPB17EPX are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement in regulated markets.

Q: Why is the PMPB24EPX classified as obsolete?

A: The PMPB24EPX has reached end-of-life status in the manufacturer's product portfolio. The PMPB17EPX represents the active replacement offering, providing equivalent or superior electrical performance with improved product availability and regulatory compliance.

Q: Will the higher gate charge of the PMPB17EPX affect gate drive circuit performance?

A: Gate charge is higher in the PMPB17EPX (47 nC versus 28 nC). Existing gate drive circuits must supply sufficient current to charge the gate within the required switching time. Circuit validation is necessary to confirm gate drive capability for the substitute part's higher gate charge specification.
