Key Parameters

Substitute Part Grouping Explanation

Substitution of the MJ11016 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for collector current rating (30 A), collector-emitter breakdown voltage (120 V), saturation voltage characteristics (4V @ 300mA, 30A), DC current gain (1000 @ 20A, 5V), maximum power dissipation (200 W), transition frequency (4 MHz), operating temperature range (-55°C to 200°C), and Through Hole TO-204 (TO-3) package configuration.

The MJ11016G qualifies as a direct substitute based on complete parameter alignment across all electrical specifications and mechanical packaging requirements. The primary distinction between these parts is product status and compliance certification, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MJ11016G is the direct functional equivalent of the MJ11016 for all electrical and mechanical applications. Selection between these parts is determined by regulatory and procurement requirements rather than technical performance.

For new designs and ongoing production: The MJ11016G is the appropriate selection. This part maintains Active product status, ensuring long-term availability and supply chain continuity. The MJ11016G carries ROHS3 compliance certification, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

For legacy system maintenance: The MJ11016 remains electrically and mechanically compatible with existing designs. However, procurement of the MJ11016 is subject to obsolescence constraints and limited inventory availability. The MJ11016G provides identical functional performance and direct pin-for-pin compatibility for retrofit or replacement applications.

Both parts are manufactured by onsemi and share the same base product number (MJ11016), confirming their equivalence as NPN Darlington transistors within the MJ110 series.

Frequently Asked Questions (FAQ)

Q: Can the MJ11016G be used as a direct replacement for the MJ11016 in existing circuits?

A: Yes. The MJ11016G is electrically and mechanically identical to the MJ11016. All electrical parameters, including collector current rating (30 A), breakdown voltage (120 V), saturation voltage (4V @ 300mA, 30A), current gain (1000 @ 20A, 5V), power dissipation (200 W), and operating temperature range (-55°C to 200°C) are identical. The TO-204 (TO-3) Through Hole package configuration is unchanged, enabling direct pin-for-pin substitution without circuit modification.

Q: What is the primary difference between the MJ11016 and MJ11016G?

A: The MJ11016 is classified as Obsolete, while the MJ11016G carries Active product status. Additionally, the MJ11016G is ROHS3 compliant, whereas the MJ11016 is RoHS non-compliant. These differences reflect manufacturing and regulatory updates rather than functional or electrical changes.

Q: Are there any package or pinout differences between these parts?

A: No. Both the MJ11016 and MJ11016G use identical TO-204AA (TO-3) Through Hole packaging. Pinout, lead configuration, and mechanical dimensions are unchanged, confirming full compatibility for PCB layouts and socket-based applications.

Q: Why should new designs use the MJ11016G instead of the MJ11016?

A: The MJ11016G is the active production part with confirmed long-term availability. The MJ11016 is obsolete and subject to limited inventory and supply discontinuation. For design continuity and procurement reliability, the MJ11016G is the standard selection for new applications.

Q: Are both parts suitable for high-current switching applications rated at 30 A?

A: Yes. Both the MJ11016 and MJ11016G are rated for maximum collector current of 30 A and are designed for high-current switching and amplification in power electronics applications. Electrical performance under rated conditions is identical between the two parts.

Q: What is the significance of the ROHS3 compliance on the MJ11016G?

A: ROHS3 compliance indicates that the MJ11016G meets current environmental and hazardous substance restrictions applicable to electronic components. This certification is required for distribution in regulated markets and for integration into systems subject to environmental compliance standards. The MJ11016, as a non-compliant part, may face restrictions in certain procurement and distribution channels.
