• Power - Peak Pulse: 500W
• Operating Temperature Range: -55°C to 175°C (TJ)

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial
• Bidirectional Channels: 1
• Type: Zener

Compliance Parameters (Must Match Exactly):

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

The SA160CA A0G meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SA160CA A0G is a direct functional equivalent to the SA160CA B0G and is suitable for substitution in all applications where the original part was specified. The substitute part maintains identical electrical performance across all critical parameters including reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power rating.

The SA160CA A0G carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and identical moisture sensitivity classification (MSL 1), confirming compatibility with existing manufacturing and assembly processes.

The through-hole axial package format (DO-204AC, DO-15) is identical between the main part and substitute, permitting direct board-level replacement without circuit layout modification or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the SA160CA A0G be used as a direct replacement for the SA160CA B0G?

A: Yes. The SA160CA A0G is a direct functional equivalent. All electrical parameters, mechanical specifications, and compliance certifications are identical. The parts are pin-compatible and interchangeable at the board level.

Q: What is the difference between the SA160CA B0G and SA160CA A0G?

A: The primary difference is product status. The SA160CA B0G is discontinued at DiGi Electronics, while the SA160CA A0G maintains active status. The alphanumeric suffix (B0G versus A0G) indicates manufacturing date code or production batch designation. All functional and electrical characteristics are identical.

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

A: No. Both parts use the DO-204AC (DO-15) axial through-hole package. Mounting orientation, lead spacing, and board footprint are identical. No PCB redesign is required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SA160CA B0G and SA160CA A0G are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification. They are equivalent for regulatory and environmental compliance purposes.

Q: What voltage ratings should I verify before substitution?

A: Confirm that your application requires a 160V reverse standoff voltage with 259V maximum clamping voltage at 2A peak pulse current. These parameters define the protection threshold and must match your circuit overvoltage protection requirements.

Q: Can I use the SA160CA A0G in high-temperature applications?

A: Yes. The operating temperature range is -55°C to 175°C (TJ) for both parts, supporting applications across industrial and automotive temperature specifications.
