The SA110CA A0G meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SA110CA A0G is a direct functional equivalent to the SA110CA B0G and is suitable for replacement in all applications where the original part was specified. The substitute part maintains identical electrical performance across all rated parameters, including voltage ratings, current handling, and thermal operating range.

The primary distinction between the two parts is product status: the SA110CA B0G is discontinued at DiGi Electronics, while the SA110CA A0G maintains active status with current inventory availability (938 pieces in stock). Both parts carry identical compliance certifications (ROHS3 Compliant, REACH Unaffected) and moisture sensitivity ratings (MSL 1 - Unlimited), ensuring equivalent reliability and regulatory compliance in end-use applications.

No design modifications, circuit adjustments, or additional validation testing are required when substituting the SA110CA A0G for the SA110CA B0G, as all electrical, mechanical, and environmental specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can the SA110CA A0G be used as a direct replacement for the SA110CA B0G?

A: Yes. The SA110CA A0G is a direct equivalent. All electrical parameters (voltage ratings, current ratings, power dissipation, temperature range) and mechanical specifications (package type, mounting configuration) are identical. No circuit modifications are required.

Q: What is the difference between the SA110CA B0G and SA110CA A0G?

A: The parts are electrically and mechanically identical. The only difference is the product status designation: SA110CA B0G is discontinued at DiGi Electronics, while SA110CA A0G is active with current inventory availability.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the SA110CA B0G and SA110CA A0G carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited moisture sensitivity level).

Q: What are the critical parameters that define substitution eligibility for this TVS diode?

A: Substitution eligibility is determined by exact matching of: Reverse Standoff Voltage (110V), Breakdown Voltage (122V minimum), Clamping Voltage (177V maximum), Peak Pulse Current (2.9A), Peak Pulse Power (500W), Operating Temperature Range (-55°C to 175°C), Package Type (DO-204AC/DO-15 Axial), and Compliance Status (ROHS3, REACH Unaffected).

Q: Can this TVS diode be used in power line protection applications?

A: No. The SA110CA B0G and SA110CA A0G are specified for general-purpose applications only. Power line protection applications require components specifically rated and certified for that function.

Q: What is the operating temperature range for these TVS diodes?

A: Both parts operate across a junction temperature range of -55°C to 175°C (TJ), providing performance across extended industrial and commercial temperature environments.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use identical through-hole axial packaging (DO-204AC/DO-15 configuration) with identical pinout and mechanical dimensions. Direct board-level substitution is possible without any physical modifications.
