Key Parameters

Substitute Part Grouping Explanation

Substitution of the PESD2USB3B/CX is determined by strict equivalence across the following critical parameters:

• Bidirectional channel configuration (2 channels required)
• Voltage ratings: Reverse standoff 4V (Max) and breakdown minimum 6V
• Peak pulse current capability: 9.5A (8/20µs)
• Package specification: 10-WLCSP (1.57x1.17) surface mount
• Operating temperature range: -40°C to 125°C
• Capacitance characteristic: 0.29pF @ 1MHz
• Compliance certifications: ROHS3, REACH Unaffected

The substitute part PESD2USB3B/CZ maintains identical electrical and mechanical specifications while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The PESD2USB3B/CZ is the direct equivalent substitute for the obsolete PESD2USB3B/CX. Both components are manufactured by Nexperia USA Inc. and share identical electrical specifications, mechanical dimensions, and compliance certifications (ROHS3 Compliant, REACH Unaffected). The primary distinction is product lifecycle status: PESD2USB3B/CZ is currently in active production, ensuring long-term availability and supply chain reliability.

For new designs or production continuity, PESD2USB3B/CZ is the appropriate selection. The Tape & Reel packaging format of the substitute part is standard for high-volume manufacturing and automated assembly processes. Both parts are functionally interchangeable at the circuit level, with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Can PESD2USB3B/CZ be used as a direct replacement for PESD2USB3B/CX in existing designs?

A: Yes. Both parts are electrically and mechanically identical. No circuit modifications, PCB layout changes, or firmware updates are required. The components are pin-compatible and functionally equivalent.

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

A: The primary difference is product status and packaging format. PESD2USB3B/CX is obsolete, while PESD2USB3B/CZ is active production. PESD2USB3B/CZ is supplied in Tape & Reel format, which is standard for automated assembly. Both maintain identical electrical performance and compliance certifications.
