Substitute Part Grouping Explanation

Substitution of the TIP117TU is determined by strict equivalence across the following critical parameters:

• Transistor Type: PNP - Darlington configuration
• Current Rating: 2 A maximum collector current
• Voltage Rating: 100 V collector-emitter breakdown voltage
• Saturation Characteristics: 2.5 V maximum Vce saturation at specified base and collector currents
• Current Gain: Minimum 1000 hFE at 1 A collector current and 4 V Vce
• Power Dissipation: 2 W maximum
• Mounting and Package: Through Hole TO-220-3 configuration

The TIP117G qualifies as a direct substitute because it maintains identical electrical specifications across all critical parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TIP117G is the direct equivalent substitute for the TIP117TU. Both parts share identical electrical specifications, thermal ratings, and mechanical packaging. The primary distinction is product lifecycle status: the TIP117TU is Obsolete, while the TIP117G maintains Active status with current manufacturing support.

The TIP117G provides additional compliance advantages, including ROHS3 certification, which aligns with modern regulatory requirements. Both parts carry REACH Unaffected status and EAR99 export classification.

For new designs or ongoing production requiring PNP Darlington transistors with 100 V / 2 A ratings in TO-220-3 packages, the TIP117G is the appropriate selection. For legacy system maintenance where TIP117TU components are being replaced, the TIP117G provides direct functional and mechanical compatibility without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the TIP117G be used as a direct replacement for the TIP117TU in existing circuits?

A: Yes. The TIP117G is electrically and mechanically identical to the TIP117TU across all specified parameters. No circuit modifications are required for substitution.

Q: What is the primary reason to substitute the TIP117TU?

A: The TIP117TU is classified as Obsolete and no longer in active production. The TIP117G is the active equivalent that maintains full electrical compatibility while ensuring ongoing supply availability.

Q: Are there any package differences between these parts?

A: Both parts use the TO-220-3 Through Hole package. The TIP117G is supplied in Tube packaging, while the TIP117TU packaging type was not specified. This does not affect electrical or mechanical compatibility in circuit applications.

Q: Does the TIP117G meet modern compliance standards?

A: Yes. The TIP117G is ROHS3 Compliant and carries REACH Unaffected status, meeting current regulatory requirements for electronic components.

Q: Are the thermal characteristics identical?

A: Yes. Both parts are rated for maximum junction temperature of 150°C and 2 W power dissipation. The TIP117G specifies an operating temperature range of -65°C to 150°C, providing additional low-temperature specification clarity.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution is determined by matching transistor type (PNP - Darlington), collector current rating (2 A), collector-emitter breakdown voltage (100 V), saturation voltage (2.5 V @ 8mA, 2A), current gain (1000 minimum @ 1A, 4V), and power rating (2 W).
