Key Parameters

Substitute Part Grouping Explanation

Substitution of the PESD1USB3S/CX is determined by strict equivalence across the following critical parameters:

• Electrical Characteristics: Breakdown voltage minimum (6V), peak pulse current rating (8A at 8/20µs), and capacitance (0.45pF @ 1MHz)
• Channel Configuration: 2-channel unidirectional topology
• Package Specification: 5-WLCSP (0.77x1.17) surface mount package
• Compliance & Certifications: ROHS3 compliance, MSL Level 1, REACH unaffected status
• Application Compatibility: HDMI and USB protection circuits

The substitute part PESD1USB3S/CZ meets all these criteria while offering an active product status, ensuring continued availability and manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The PESD1USB3S/CZ is the direct substitute for the obsolete PESD1USB3S/CX. Both components share identical electrical specifications, package geometry, and compliance certifications. The substitute offers an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C), providing enhanced thermal performance without compromising any specified parameters. As an active product with current manufacturer support, PESD1USB3S/CZ ensures supply chain continuity and access to technical documentation and support resources.

Frequently Asked Questions (FAQ)

Q: Can PESD1USB3S/CZ be used as a direct replacement for PESD1USB3S/CX in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 6V breakdown voltage, 8A peak pulse current, 0.45pF capacitance, 2-channel configuration, and identical 5-WLCSP package dimensions (0.77x1.17mm). No circuit modifications are required.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. PESD1USB3S/CX is obsolete, while PESD1USB3S/CZ is active. Additionally, PESD1USB3S/CZ specifies a 5V maximum reverse standoff voltage and supports an extended operating temperature range to 125°C.

Q: Are there packaging differences between these parts?

A: Both use the 5-WLCSP (0.77x1.17mm) surface mount package. PESD1USB3S/CZ is available in Tape & Reel (TR) format, which is standard for production quantities.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PESD1USB3S/CX and PESD1USB3S/CZ are ROHS3 compliant, MSL Level 1, and REACH unaffected.

Q: Which applications are supported by the substitute part?

A: PESD1USB3S/CZ is rated for HDMI and USB protection applications, identical to the original part.
