Substitute Part Grouping Explanation

Substitution of the MJH11017 is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitute relationships:

Electrical Parameters (Must Match):

• Transistor Type: PNP - Darlington configuration
• Current - Collector (Ic) (Max): 15 A
• Voltage - Collector Emitter Breakdown (Max): 150 V
• Vce Saturation (Max) @ Ib, Ic: 4V @ 150mA, 15A
• Current - Collector Cutoff (Max): 1 mA
• DC Current Gain (hFE) (Min) @ Ic, Vce: 400 @ 10A, 5V
• Power - Max: 150 W
• Frequency - Transition: 3 MHz
• Operating Temperature Range: -65°C to 150°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package compatibility with circuit board layout requirements

Substitute parts must satisfy all electrical specifications and maintain through-hole mounting compatibility. Package variants (TO-218-3 versus TO-247-3) represent different physical form factors suitable for different thermal management and board layout configurations while maintaining identical electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The MJH11017G serves as a direct electrical equivalent to the obsolete MJH11017. Both components share identical electrical specifications across all critical parameters: collector current rating, breakdown voltage, saturation characteristics, current gain, power dissipation, and operating temperature range.

Product Status Consideration: The MJH11017 is classified as obsolete, while the MJH11017G maintains active product status. Selection of the MJH11017G ensures access to current manufacturing, quality assurance, and supply chain continuity.

Compliance Consideration: The MJH11017G achieves ROHS3 compliance, whereas the original MJH11017 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must transition to the MJH11017G.

Package Consideration: The primary difference between these parts is the package form factor. The MJH11017 uses TO-218-3 packaging, while the MJH11017G uses TO-247-3 packaging. Both are through-hole mounted devices. Package selection depends on circuit board layout, thermal management requirements, and mechanical mounting constraints. TO-247-3 packaging typically provides enhanced thermal performance through improved lead geometry and mounting surface area.

Frequently Asked Questions (FAQ)

Q: Can the MJH11017G directly replace the MJH11017 in existing circuit designs?

A: Electrical replacement is direct. All electrical parameters are identical. Physical replacement requires verification that the TO-247-3 package footprint accommodates the circuit board layout and mechanical mounting structure. Pin configuration and lead spacing differ between TO-218-3 and TO-247-3 packages.

Q: What is the primary reason to transition from MJH11017 to MJH11017G?

A: The MJH11017 is obsolete. The MJH11017G is the active equivalent part from the same manufacturer, ensuring continued supply, manufacturing support, and compliance with current regulatory standards.

Q: Are there electrical performance differences between MJH11017 and MJH11017G?

A: No. Both components are specified identically across all electrical parameters: collector current, breakdown voltage, saturation voltage, current gain, power rating, transition frequency, and operating temperature range.

Q: How do the TO-218-3 and TO-247-3 packages differ?

A: TO-218-3 and TO-247-3 are distinct through-hole package form factors with different physical dimensions, lead configurations, and mounting surface areas. TO-247-3 typically provides superior thermal performance. Package selection is determined by circuit board design, thermal management strategy, and mechanical mounting requirements.

Q: Is the MJH11017G suitable for applications requiring RoHS compliance?

A: Yes. The MJH11017G is ROHS3 compliant. The original MJH11017 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must use the MJH11017G.

Q: What certifications apply to the MJH11017G?

A: The MJH11017G is ROHS3 compliant and REACH unaffected. ECCN classification is EAR99.
