Substitute Part Grouping Explanation

Substitution of the MJ11022 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 Type: NPN - Darlington
• Current - Collector (Ic) (Max): 15 A
• Voltage - Collector Emitter Breakdown (Max): 250 V
• Vce Saturation (Max) @ Ib, Ic: 3.4 V @ 150 mA, 15 A
• Current - Collector Cutoff (Max): 1 mA
• DC Current Gain (hFE) (Min) @ Ic, Vce: 400 @ 10 A, 5 V
• Power - Max: 175 W
• Operating Temperature: -65°C to 200°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: TO-204AA, TO-3

The MJ11022G qualifies as a direct substitute because it maintains identical electrical specifications and mechanical packaging while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The MJ11022G is the direct substitute for the obsolete MJ11022. Both components are manufactured by onsemi and maintain identical electrical and mechanical specifications across all critical parameters. The MJ11022G offers the following advantages:

Product Status: The MJ11022G carries Active product status, ensuring continued availability and manufacturer support, whereas the MJ11022 is classified as Obsolete.

Regulatory Compliance: The MJ11022G is ROHS3 Compliant, meeting current environmental and hazardous substance restrictions. The original MJ11022 is RoHS non-compliant.

REACH Status: Both parts maintain REACH Unaffected classification.

Inventory Availability: The MJ11022G is available with 1128 pieces in stock as new original inventory.

For applications currently utilizing the MJ11022, direct substitution with MJ11022G is supported without circuit modification or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the MJ11022G be used as a direct replacement for the MJ11022?

A: Yes. The MJ11022G is a direct substitute. Both components share identical electrical ratings (15 A collector current, 250 V breakdown voltage, 175 W power dissipation, 400 hFE minimum gain) and mechanical packaging (TO-204 / TO-3 through-hole). No circuit redesign is required.

Q: What is the primary reason for substituting the MJ11022?

A: The MJ11022 is classified as Obsolete. The MJ11022G provides continuity of supply with Active product status and improved regulatory compliance (ROHS3).

Q: Are the thermal characteristics identical between MJ11022 and MJ11022G?

A: Yes. Both components operate across the same temperature range (-65°C to 200°C junction temperature) and dissipate the same maximum power (175 W).

Q: Does the package differ between these parts?

A: No. Both the MJ11022 and MJ11022G use the TO-204AA / TO-3 through-hole package. PCB footprints and mounting procedures are identical.

Q: What is the difference in packaging format between the two parts?

A: The MJ11022 is supplied in standard packaging, while the MJ11022G is supplied in Tray packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Are there any compliance differences?

A: Yes. The MJ11022G is ROHS3 Compliant, whereas the MJ11022 is RoHS non-compliant. Both maintain REACH Unaffected status. For applications subject to RoHS requirements, the MJ11022G is the appropriate selection.

Q: Can I use the MJ11022G in high-temperature applications?

A: Yes. The MJ11022G maintains the full operating temperature range of -65°C to 200°C (junction temperature), identical to the MJ11022.
