Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1.5KE110CA-T is determined by the following critical parameters:

• Voltage - Reverse Standoff: 94V (±tolerance)
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Power - Peak Pulse: 1500W
• Type: Zener, Bidirectional
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 175°C (TJ)

All substitute parts listed maintain these core electrical specifications. Package variations (DO-201AA, DO-27, DO-201AE, DO-13) are acceptable within through-hole mounting category, provided PCB layout accommodates the specific package footprint.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain electrical equivalence to the 1.5KE110CA-T across voltage and power specifications. Selection should prioritize active product status for long-term availability.

Primary substitutes (DO-201AA package compatibility):

• 1.5KE110CA-E3/54 (Vishay): Active status, TransZorb series, identical electrical parameters
• 1.5KE110CA (Taiwan Semiconductor Corporation): Active status, manufacturer-recommended equivalent
• 1.5KE110CA-B (Littelfuse): Active status, bulk packaging option

Alternative with package change (DO-201AE):

• 1.5KE110CA-TP (Micro Commercial Co): Active status, requires PCB footprint verification for DO-201AE

Alternative with package change (DO-13):

• 1N6064A (Solid State Inc.): Active status, significantly higher inventory availability, requires PCB layout modification for DO-13 package

All substitute parts are ROHS3 compliant and rated for -55°C to 175°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can 1.5KE110CA-T be directly replaced with 1N6064A? A: Electrical parameters are equivalent. However, 1N6064A uses DO-13 package versus the original DO-201AA package. PCB footprint and lead spacing differ; layout modification is required.

Q: What is the difference between 1.5KE110CA-E3/54 and 1.5KE110CAHE3_A/C? A: Both are Vishay TransZorb series with identical electrical specifications. The 1.5KE110CAHE3_A/C variant includes AEC-Q101 automotive qualification. Selection depends on application requirements.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitute parts meet ROHS3 compliance requirements.

Q: Does peak pulse current variation (9.9A to 10.3A) affect substitution? A: No. All values remain within the 1500W power rating envelope and maintain equivalent clamping performance at the specified 152V maximum.

Q: Which substitute offers best long-term availability? A: 1.5KE110CA (Taiwan Semiconductor Corporation) and 1.5KE110CA-B (Littelfuse) are both active-status products from established manufacturers with consistent supply channels.
