Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1.5KE110A R0G is determined by electrical and mechanical parameter equivalence within the TVS diode category. The following parameters establish substitution validity:

Electrical Parameters:

• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Current - Peak Pulse (10/1000µs): 10.3A
• Power - Peak Pulse: 1500W

Mechanical Parameters:

• Unidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: DO-201AA, DO-27, Axial
• Operating Temperature Range: -55°C to 175°C (TJ)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must match all electrical parameters, support identical mounting and package specifications, and maintain compliance certifications to ensure direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The 1.5KE110A substitute part is a direct functional equivalent to the 1.5KE110A R0G. Both components are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, thermal operating range, and mechanical package configuration.

The primary distinction between the main part and substitute is product status and packaging format. The 1.5KE110A R0G is discontinued at DiGi Electronics, whereas the 1.5KE110A is currently active with higher inventory availability (12,300 pieces in stock versus 1,049 pieces). The substitute part is supplied in Tape & Reel (TR) format, whereas the main part was supplied in bulk packaging.

Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental standards. The electrical parameters, including reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power, are identical across both components.

For applications requiring the 1.5KE110A R0G specification, the 1.5KE110A substitute provides equivalent performance without circuit modification or re-qualification.
