CPDQC5V0CSP-IPHF Equivalent & Substitute Parts

Part Overview

The CPDQC5V0CSP-IPHF is a Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This component features a 5V reverse standoff voltage with an 18V maximum clamping voltage and 2A peak pulse current rating in a compact 0402 surface mount package.

The CPDQC5V0CSP-IPHF is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term component sourcing strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPDQC5V0CSP-IPHF is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 5V (Max)
• Voltage - Clamping (Max) @ Ipp: 18V
• Current - Peak Pulse (10/1000µs): 2A (8/20µs)
• Package / Case: 0402 (1006 Metric)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• RoHS Compliance: ROHS3 Compliant

The CPDQC5V0SC-HF meets all substitution criteria. Both parts share identical voltage ratings, current handling capacity, package specifications, temperature range, and regulatory compliance. Minor variations in voltage breakdown minimum (7V vs. 6V) and capacitance (0.15pF vs. 0.2pF) remain within acceptable tolerance for general-purpose TVS applications and do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The CPDQC5V0SC-HF is the direct substitute for the obsolete CPDQC5V0CSP-IPHF. Both components are manufactured by Comchip Technology and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part carries Active product status, ensuring long-term availability and production support.

Both parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), meeting regulatory and environmental requirements for industrial and commercial applications. The substitute part offers improved inventory availability (10,100 pcs in stock versus 704 pcs for the obsolete part) and is supplied in standard Cut Tape and Digi-Reel packaging formats.

Frequently Asked Questions (FAQ)

Q: Can CPDQC5V0SC-HF be used as a direct replacement for CPDQC5V0CSP-IPHF?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical voltage ratings (5V reverse standoff, 18V clamping), current capacity (2A peak pulse), package type (0402 surface mount), and operating temperature range (-55°C to 150°C). The substitute part is manufactured by the same supplier and maintains equivalent compliance certifications.

Q: What are the differences between these two parts?

A: The primary difference is product status: CPDQC5V0CSP-IPHF is obsolete while CPDQC5V0SC-HF is active. Minor parameter variations include voltage breakdown minimum (7V vs. 6V) and capacitance (0.15pF vs. 0.2pF at 1MHz), which do not affect functional equivalence for general-purpose TVS applications. Peak pulse power is marginally higher in the substitute (36W vs. 35W).

Q: Are there packaging differences between these parts?

A: Both parts use the same 0402 (1006 Metric) surface mount package. The substitute part is available in Cut Tape and Digi-Reel packaging, while the obsolete part was supplied in standard packaging. PCB footprints and assembly processes remain identical.

Q: Is the substitute part RoHS compliant?

A: Yes. CPDQC5V0SC-HF is ROHS3 compliant, matching the compliance status of the original part. Both components also maintain Moisture Sensitivity Level 1 (Unlimited).

Q: Why should I transition to the substitute part?

A: The obsolete CPDQC5V0CSP-IPHF has limited remaining inventory (704 pcs). The substitute CPDQC5V0SC-HF is in active production with significantly higher stock levels (10,100 pcs), ensuring reliable long-term sourcing for new designs and production continuity.
