Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIP117 is determined by electrical and mechanical parameter equivalence. The substitute part must satisfy the following criteria:

• Transistor Configuration: PNP - Darlington topology
• Maximum Collector Current: 2 A minimum rating
• Collector-Emitter Breakdown Voltage: 100 V minimum rating
• Saturation Voltage Characteristics: 2.5V @ 8mA, 2A
• DC Current Gain: 1000 @ 1A, 4V minimum
• Power Dissipation: 2 W minimum rating
• Operating Temperature Range: -65°C to 150°C
• Package Configuration: TO-220-3 Through Hole mounting

The TIP117G meets all specified electrical and mechanical parameters and is classified as an Active product, providing design continuity for applications currently utilizing the obsolete TIP117.

Parameter Comparison

Engineering Selection Recommendations

The TIP117G is the direct equivalent substitute for the obsolete TIP117. All electrical parameters, mechanical specifications, and thermal characteristics are identical. The TIP117G is classified as Active product status, ensuring continued availability and supply chain reliability.

The TIP117G achieves ROHS3 compliance, whereas the original TIP117 is RoHS non-compliant. This compliance improvement provides regulatory advantage for applications subject to RoHS directives. Both components maintain REACH Unaffected status and EAR99 export classification.

For applications currently specified with TIP117, direct substitution with TIP117G requires no circuit modifications, thermal management adjustments, or layout changes. The TO-220-3 package configuration remains identical, supporting existing PCB designs and mechanical assemblies.

Frequently Asked Questions (FAQ)

Q: Can TIP117G be used as a direct replacement for TIP117 in existing designs?

A: Yes. The TIP117G provides identical electrical performance across all specified parameters including collector current, breakdown voltage, saturation characteristics, and current gain. The TO-220-3 package configuration is unchanged, supporting direct PCB substitution without design modification.

Q: What is the primary reason for substituting TIP117 with TIP117G?

A: The TIP117 is classified as Obsolete product status. The TIP117G is an Active equivalent that maintains all electrical and mechanical specifications while providing improved regulatory compliance through ROHS3 certification.

Q: Are there thermal management differences between TIP117 and TIP117G?

A: No. Both components are rated for 2 W maximum power dissipation and operate across the identical temperature range of -65°C to 150°C. Thermal design considerations remain unchanged.

Q: Does the TIP117G require different PCB layout or mounting procedures?

A: No. The TIP117G uses the same TO-220-3 Through Hole package configuration as the TIP117. Existing PCB layouts, mounting hardware, and assembly procedures are directly compatible.

Q: What compliance certifications does TIP117G provide?

A: The TIP117G is ROHS3 compliant and maintains REACH Unaffected status. Both components carry EAR99 export classification. The TIP117 is RoHS non-compliant, making TIP117G the preferred choice for applications requiring regulatory compliance.

Q: Is the DC current gain specification identical between both parts?

A: Yes. Both TIP117 and TIP117G specify minimum DC current gain (hFE) of 1000 at 1A collector current and 4V collector-emitter voltage.
