Substitution of the MJD42C-13 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Must Match):

• Transistor polarity: PNP
• Maximum collector current: 6 A
• Collector-emitter breakdown voltage: 100 V
• Saturation voltage: 1.5 V @ 600mA, 6A
• Collector cutoff current: 1 µA
• DC current gain (hFE): 30 minimum @ 300mA, 4V
• Maximum power dissipation: 1.5 W
• Transition frequency: 3 MHz
• Operating temperature range: -55°C to 150°C

Mechanical Parameters (Must Match):

• Package type: TO-252-3 (DPAK)
• Mounting technology: Surface Mount
• Lead configuration: 2 Leads + Tab

Compliance Parameters:

• RoHS3 compliance required
• REACH unaffected status required

The MJD42CQ-13 meets all specified criteria and is classified as a parametric equivalent with automotive-grade qualification.

Engineering Selection Recommendations

MJD42C-13 (Standard Grade)

The MJD42C-13 is suitable for general industrial and commercial applications requiring PNP high-voltage power switching. The part maintains active production status with 962 units in current inventory. This variant is ROHS3 compliant and REACH unaffected, meeting standard environmental regulations for unrestricted distribution.

MJD42CQ-13 (Automotive Grade)

The MJD42CQ-13 is the automotive-qualified equivalent, carrying AEC-Q101 certification and Moisture Sensitivity Level (MSL) 1 rating. This variant is specified for automotive and mission-critical applications where enhanced reliability documentation and qualification testing are required. The MJD42CQ-13 offers superior inventory availability with 3,250 units in stock. Both variants share identical electrical and mechanical specifications, differing only in qualification level and environmental classification.

Selection between these parts depends on application requirements: use MJD42C-13 for standard industrial applications, or MJD42CQ-13 for automotive, aerospace, or high-reliability systems requiring AEC-Q101 compliance.

Frequently Asked Questions (FAQ)

Q: Can MJD42CQ-13 be used as a direct replacement for MJD42C-13?

A: Yes. The MJD42CQ-13 is a parametric equivalent with identical electrical and mechanical specifications. The automotive-grade qualification of the MJD42CQ-13 does not restrict its use in standard industrial applications. Direct PCB-level substitution is supported without circuit modification.

Q: What is the difference between MJD42C-13 and MJD42CQ-13?

A: Both parts are manufactured by Diodes Incorporated with identical electrical performance across all specified parameters. The MJD42CQ-13 carries AEC-Q101 automotive qualification and MSL 1 moisture sensitivity rating, making it suitable for automotive and high-reliability applications. The MJD42C-13 is specified for general industrial use. Functionally, they are interchangeable.

Q: Are both parts available in the same packaging?

A: Yes. Both MJD42C-13 and MJD42CQ-13 are supplied in TO-252-3 (DPAK) surface mount packages with identical lead configurations (2 Leads + Tab). Both are available in Tape & Reel (TR) packaging for automated assembly.

Q: Do these parts require different PCB footprints?

A: No. Both parts use the identical TO-252-3 (DPAK) package footprint. No PCB redesign or layout modification is necessary when substituting between these parts.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both MJD42C-13 and MJD42CQ-13 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for unrestricted distribution in regulated markets.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the industrial temperature range of -55°C to 150°C (junction temperature). This specification is identical for MJD42C-13 and MJD42CQ-13.

Q: Can these parts be used interchangeably in automotive applications?

A: The MJD42CQ-13 is specifically qualified for automotive applications under AEC-Q101 and carries MSL 1 rating. For automotive designs, MJD42CQ-13 is the specified choice. The MJD42C-13 may be used in non-safety-critical automotive subsystems where automotive qualification is not contractually required.
