Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1.5KE110CA-TP is determined by strict equivalence across the following critical parameters:

• Bidirectional Channels: 1
• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Power - Peak Pulse: 1500W (1.5kW)
• Mounting Type: Through Hole
• Package / Case: DO-201 series, Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Type: Zener
• RoHS Status: ROHS3 Compliant

The substitute part 1.5KE110CA from Taiwan Semiconductor Corporation meets all specified electrical and mechanical parameters, maintaining identical voltage ratings, power dissipation capability, and thermal operating range. Both parts share the same base product number (1.5KE110) and are classified as active products with full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the 1.5KE110CA-TP and 1.5KE110CA are active products with full RoHS3 and REACH compliance. Selection between these parts should be based on:

• Manufacturer availability and supply chain requirements
• Package variant compatibility (DO-201AE versus DO-201AA/DO-27)
• Current inventory levels and lead time considerations
• Procurement cost and volume pricing structures

The electrical performance, thermal characteristics, and regulatory compliance are equivalent across both parts, making either suitable for applications requiring 1500W peak pulse power dissipation at 152V clamping voltage in through-hole axial configurations.

Frequently Asked Questions (FAQ)

Q: Can the 1.5KE110CA substitute for the 1.5KE110CA-TP in all applications?

A: Yes, provided the package variant (DO-201AA or DO-27) is compatible with your PCB layout. Both parts maintain identical electrical specifications including voltage ratings, power dissipation, and operating temperature range.

Q: What is the difference between DO-201AE and DO-201AA packages?

A: Both are axial through-hole packages in the DO-201 family. Physical dimensions may vary slightly between variants. Verify PCB footprint compatibility before substitution.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What determines whether a part qualifies as a substitute?

A: Substitution requires equivalence across all critical electrical parameters: reverse standoff voltage (94V), breakdown voltage (105V), clamping voltage (152V), peak pulse power (1500W), bidirectional channel count (1), and operating temperature range (-55°C to 175°C).

Q: Is the 1.5KE110CA available in the same packaging as the main part?

A: The substitute is available in DO-201AA and DO-27 axial packages. Confirm mechanical compatibility with your specific application requirements before selection.
