Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CPDQC5V0USP-IPHF is determined by the following critical parameters:

• Package / Case: Must be 0402 (1006 Metric) for PCB layout compatibility
• Mounting Type: Must be Surface Mount
• Voltage - Reverse Standoff: Must be 5V or lower to maintain circuit protection thresholds
• Voltage - Clamping (Max) @ Ipp: Must not exceed 15V to ensure adequate transient suppression
• Current - Peak Pulse: Must meet or exceed 2.5A (8/20µs) to handle specified surge conditions
• Operating Temperature Range: Must support -55°C ~ 150°C (TJ) for thermal compatibility
• RoHS Compliance: Must maintain ROHS3 Compliant status for regulatory alignment

The CPDQC5V0USC-HF qualifies as a manufacturer-recommended substitute, meeting all critical electrical and mechanical parameters while offering improved current handling capability and active product status.

Parameter Comparison

Engineering Selection Recommendations

The CPDQC5V0USC-HF is the manufacturer-recommended substitute for the obsolete CPDQC5V0USP-IPHF. Both components maintain identical package, mounting type, and thermal operating range specifications. The substitute part offers enhanced current handling (3A versus 2.5A peak pulse) and increased power dissipation capability (45W versus 30W), providing improved margin for transient protection without compromising voltage clamping characteristics.

Both parts maintain ROHS3 compliance and are manufactured by Comchip Technology, ensuring regulatory alignment and supply chain continuity. The substitute part's active product status ensures long-term availability and manufacturing support, addressing the obsolescence constraint of the original component.

Frequently Asked Questions (FAQ)

Q: Can the CPDQC5V0USC-HF be used as a direct replacement for the CPDQC5V0USP-IPHF?

A: Yes. Both components share identical package (0402), mounting type (Surface Mount), voltage ratings (5V reverse standoff, 15V clamping), and operating temperature range (-55°C ~ 150°C). The substitute part meets or exceeds all electrical specifications of the original component.

Q: What is the difference in current handling between these parts?

A: The CPDQC5V0USC-HF handles 3A peak pulse current (8/20µs) compared to 2.5A for the CPDQC5V0USP-IPHF. This 20% increase in current capacity provides additional protection margin without affecting voltage clamping performance.

Q: Are there any package or PCB layout considerations when substituting?

A: No. Both parts use the identical 0402 (1006 Metric) package and SOD-923F supplier device package, requiring no PCB layout modifications or footprint changes.

Q: Why is the original part classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The CPDQC5V0USC-HF maintains active status, ensuring continued manufacturing support and supply availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and carry identical regulatory certifications (ECCN: EAR99, HTSUS: 8541.10.0080), maintaining full compliance with applicable standards.
