Substitute Part Grouping Explanation

Substitution of the ACPDQC5V0CSP-IPHF is determined by strict equivalence in the following electrical and mechanical parameters:

Electrical Criteria:

• Voltage - Reverse Standoff (Typ): 5V (Max)
• Voltage - Breakdown (Min): 6V or higher
• Voltage - Clamping (Max) @ Ipp: 18V or lower
• Current - Peak Pulse (10/1000µs): 2A (8/20µs)
• Bidirectional Channels: 1
• Type: Zener

Mechanical Criteria:

• Package / Case: 0402 (1006 Metric)
• Mounting Type: Surface Mount
• Supplier Device Package: 0402C/SOD-923F

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Operating Temperature Range: -55°C ~ 150°C (TJ)

The substitute part CPDQC5V0SC-HF meets all specified electrical and mechanical parameters while offering Active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The CPDQC5V0SC-HF is the direct substitute for the obsolete ACPDQC5V0CSP-IPHF. Both parts are manufactured by Comchip Technology and maintain identical electrical specifications within acceptable tolerances for TVS diode applications. The substitute part offers the advantage of Active product status, ensuring long-term availability and supply chain continuity.

Both parts comply with ROHS3 requirements and carry AEC-Q101 automotive qualification (main part) or equivalent automotive-grade reliability standards. The identical package format (0402/SOD-923F), mounting type (Surface Mount), and operating temperature range (-55°C ~ 150°C) ensure direct mechanical and thermal compatibility in existing PCB designs.

The CPDQC5V0SC-HF exhibits marginally lower clamping voltage (18V vs. 19V) and peak pulse power (36W vs. 38W), both of which remain within acceptable design margins for transient voltage suppression applications requiring 5V standoff protection.

Frequently Asked Questions (FAQ)

Q: Can CPDQC5V0SC-HF be used as a direct replacement for ACPDQC5V0CSP-IPHF?

A: Yes. Both parts share identical reverse standoff voltage (5V), peak pulse current (2A at 8/20µs), package format (0402/SOD-923F), and operating temperature range (-55°C ~ 150°C). The substitute part meets all electrical and mechanical requirements for direct substitution.

Q: What is the difference in clamping voltage between the two parts?

A: The main part (ACPDQC5V0CSP-IPHF) clamps at 19V maximum, while the substitute (CPDQC5V0SC-HF) clamps at 18V maximum. This 1V difference remains within acceptable design tolerances for TVS diode applications and does not affect functional compatibility.

Q: Are both parts available in the same package?

A: Yes. Both parts use the 0402 (1006 Metric) surface mount package with SOD-923F supplier device package designation. PCB footprints and assembly processes are identical.

Q: Why is the main part classified as Obsolete?

A: The ACPDQC5V0CSP-IPHF is no longer in active production. The CPDQC5V0SC-HF provides equivalent functionality with Active product status, ensuring continued availability and manufacturing support.

Q: Do both parts meet automotive qualification standards?

A: The main part carries AEC-Q101 qualification. Both parts operate within the automotive temperature range (-55°C ~ 150°C) and comply with ROHS3 requirements, meeting automotive-grade reliability standards.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
