TIP110 NPN Darlington Transistor Equivalent & Substitute Parts

Part Overview

The TIP110 is a Bipolar (BJT) NPN Darlington transistor manufactured by onsemi, rated for 60 V collector-emitter breakdown voltage and 2 A maximum collector current in a Through Hole TO-220 package. This component is classified as Obsolete, which necessitates identification of functionally equivalent substitute parts for ongoing design support and procurement continuity. Substitute parts maintain identical electrical specifications and mechanical compatibility while offering improved product status and compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the TIP110 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

Transistor Type: NPN - Darlington
Current - Collector (Ic) (Max): 2 A
Voltage - Collector Emitter Breakdown (Max): 60 V
Vce Saturation (Max) @ Ib, Ic: 2.5 V @ 8mA, 2A
Current - Collector Cutoff (Max): 2 mA
DC Current Gain (hFE) (Min) @ Ic, Vce: 1000 @ 1A, 4V
Power - Max: 2 W
Operating Temperature Range: -65°C to 150°C (TJ)

Mechanical Parameters (Must Match):

Mounting Type: Through Hole

Engineering Selection Recommendations

TIP110G is the primary substitute for the TIP110. This part maintains complete electrical and mechanical equivalence while offering Active product status and ROHS3 compliance. The TIP110G is supplied in Tube packaging and represents the current production equivalent within the onsemi TIP110 family.

TIP110TU is an alternative substitute that maintains electrical and mechanical equivalence. This part carries ROHS3 compliance and is supplied in TO-220-3 package configuration. However, the TIP110TU is classified as Obsolete, limiting its long-term procurement viability compared to the TIP110G.

For new designs and ongoing procurement, TIP110G is the preferred selection due to Active product status and assured supply continuity. Both TIP110G and TIP110TU are suitable for direct replacement in existing applications where the TIP110 is currently specified.

Frequently Asked Questions (FAQ)

Q: Can TIP110G directly replace TIP110 in existing circuit designs?

A: Yes. The TIP110G maintains identical electrical specifications (60 V breakdown voltage, 2 A collector current, 2 W power dissipation, 1000 hFE minimum gain) and mechanical compatibility (Through Hole TO-220-3 package). Pin configuration and functional behavior are equivalent.

Q: What is the primary advantage of TIP110G over the original TIP110?

A: The TIP110G carries Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The original TIP110 is Obsolete and RoHS non-compliant.

Q: Are there differences in operating temperature range between TIP110 and its substitutes?

A: The TIP110 and TIP110G both support -65°C to 150°C (TJ) operating range. The TIP110TU specifies 150°C (TJ) maximum, which represents a narrower lower-temperature specification. For applications requiring full -65°C to 150°C range, TIP110G is the appropriate selection.

Q: What packaging formats are available for TIP110 substitutes?

A: TIP110G is supplied in Tube packaging. TIP110TU is supplied in TO-220-3 package configuration. Both maintain the Through Hole TO-220-3 mechanical form factor for PCB mounting.

Q: Is the TIP110TU suitable for new designs?

A: The TIP110TU is classified as Obsolete. While electrically and mechanically equivalent, TIP110G is the recommended selection for new designs due to Active product status and assured supply continuity.

Q: What compliance certifications apply to substitute parts?

A: TIP110G and TIP110TU both carry ROHS3 compliance and REACH Unaffected status. The original TIP110 is RoHS non-compliant, making the substitutes preferable for applications subject to RoHS requirements.
