TIP110 Equivalent & Substitute Parts

Part Overview

The TIP110 is an NPN Darlington bipolar junction transistor manufactured by Central Semiconductor Corp, designed for through-hole applications in the TO-220-3 package. This device features a 60 V collector-emitter breakdown voltage rating and operates across a temperature range of -65°C to 150°C. The TIP110 is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and production continuity. Substitute parts must maintain functional equivalence within the specified electrical and mechanical parameters while accommodating the transition from obsolete to active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIP110 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Transistor Type: NPN - Darlington configuration
• Package / Case: TO-220-3 form factor
• Mounting Type: Through Hole
• DC Current Gain (hFE): Minimum 1000 @ 1A, 4V
• Frequency - Transition: 25 MHz
• Operating Temperature Range: -65°C to 150°C (TJ)
• Vce Saturation: 2.5 V @ 8mA, 2A

Allowable Parameter Variance:

• Voltage - Collector Emitter Breakdown (Max): Equal to or greater than 60 V
• Current - Collector Cutoff (Max): Equal to or less than 2 mA

The TIP112 qualifies as a direct substitute because it maintains all mandatory parameters while exceeding the voltage rating (100 V vs. 60 V), which is permissible in applications designed for the TIP110's 60 V specification.

Engineering Selection Recommendations

Product Status Consideration: The TIP110 carries an obsolete product status, while the TIP112 TIN/LEAD is classified as active. For new designs and production continuity, the TIP112 TIN/LEAD is the appropriate selection.

Compliance and Certification: Both the TIP110 and TIP112 TIN/LEAD share identical RoHS non-compliance status, REACH unaffected classification, and ECCN/HTSUS coding (EAR99 / 8541.29.0095). Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both devices, indicating no special moisture handling requirements.

Electrical Equivalence: The TIP112 TIN/LEAD maintains all critical electrical specifications of the TIP110, including saturation voltage, current gain, and transition frequency. The elevated voltage rating (100 V vs. 60 V) does not compromise functionality in circuits designed for 60 V operation and provides additional design margin.

Packaging and Mechanical Compatibility: Both devices utilize the TO-220-3 through-hole package, ensuring direct mechanical and thermal compatibility in existing PCB layouts and heat sink assemblies.

Frequently Asked Questions (FAQ)

Q: Can the TIP112 TIN/LEAD be used as a direct replacement for the TIP110 in existing designs?

A: Yes. The TIP112 TIN/LEAD maintains electrical equivalence across all critical parameters: NPN Darlington configuration, identical saturation voltage, current gain, transition frequency, and operating temperature range. The TO-220-3 package ensures mechanical compatibility. The higher voltage rating (100 V) does not affect circuits designed for 60 V operation.

Q: What is the significance of the higher voltage rating on the TIP112?

A: The TIP112's 100 V collector-emitter breakdown voltage exceeds the TIP110's 60 V specification. In applications operating at or below 60 V, this higher rating provides additional safety margin without altering circuit behavior. The device remains fully functional within the original design parameters.

Q: Are there any compliance or certification differences between the TIP110 and TIP112 TIN/LEAD?

A: No. Both devices share identical RoHS non-compliance status, REACH unaffected classification, and regulatory coding (ECCN: EAR99; HTSUS: 8541.29.0095). Moisture Sensitivity Level is 1 (Unlimited) for both, requiring no special handling.

Q: Does the TIP112 TIN/LEAD require any PCB layout modifications?

A: No. Both devices use the TO-220-3 through-hole package with identical pin configuration and thermal characteristics. Existing PCB layouts, mounting hardware, and heat sink assemblies are fully compatible without modification.

Q: What inventory status should be considered when selecting between these parts?

A: The TIP110 is obsolete with 1330 pieces in stock. The TIP112 TIN/LEAD is active with 1000 pieces in stock. For production continuity and long-term availability, the TIP112 TIN/LEAD is the recommended selection.

Q: Are the saturation and current gain specifications identical between both devices?

A: Yes. Both the TIP110 and TIP112 TIN/LEAD specify Vce saturation of 2.5 V @ 8mA, 2A and DC current gain (hFE) of 1000 @ 1A, 4V. These parameters are critical for circuit performance and are fully matched.
