ACPDQC5V0USP-HF Equivalent & Substitute Parts

Part Overview

The ACPDQC5V0USP-HF is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for surface mount applications in the SOD-923 package. This component provides transient voltage protection with a 5V reverse standoff voltage and 20V maximum clamping voltage at peak pulse current. The part is Active status, AEC-Q101 qualified for automotive applications, and ROHS3 compliant. Substitute parts are identified based on matching electrical protection characteristics and compatible package footprints for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACPDQC5V0USP-HF are qualified based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 5V (Max)
• Voltage - Clamping (Max) @ Ipp: 20V or lower
• Current - Peak Pulse (10/1000µs): 2.5A or higher
• Unidirectional Channels: 1
• Type: Zener
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Package Compatibility: Substitute parts must use surface mount packages compatible with SOD-923 footprint requirements or equivalent land pattern dimensions. Parts listed include SOD-923, SOD-882, and DFN1006 variants, all suitable for direct board-level replacement in applications requiring transient voltage suppression at 5V standoff levels.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original ACPDQC5V0USP-HF.

Direct Comchip Substitute: CPDQC5V0USP-HF provides identical electrical specifications and SOD-923 package compatibility with higher inventory availability (4053 pcs vs. 956 pcs).

Nexperia Alternatives: PESD5V0S1UL,315 and PESD5V0S1ULD,315 offer higher peak pulse current (15A vs. 2.5A) and power dissipation (150W vs. 50W) with AEC-Q101 automotive qualification. The wettable flank variant (PESD5V0S1ULD,315) provides enhanced solderability. Package transition from SOD-923 to SOD-882 or DFN1006 requires PCB footprint verification.

PESD5V0L1ULD,315 delivers 4.6A peak pulse current with 12V clamping voltage and wettable flank construction, suitable for applications with lower transient energy requirements.

PESD5V0U1UL,315 offers minimal capacitance (2pF) for high-frequency signal integrity applications, though clamping voltage and peak pulse current specifications are not provided.

Littelfuse Alternative: SP3031-01ETG provides 5A peak pulse current with 7.5V typical clamping voltage and AEC-Q101 qualification. Operating temperature range (-40°C to 125°C) is narrower than Nexperia variants (-55°C to 150°C).

Frequently Asked Questions (FAQ)

Q: Can PESD5V0S1UL,315 directly replace ACPDQC5V0USP-HF on the same PCB? A: Electrical substitution is valid based on matching 5V reverse standoff voltage and 20V clamping voltage. However, package footprint differs: PESD5V0S1UL,315 uses SOD-882 while ACPDQC5V0USP-HF uses SOD-923. PCB land pattern modification is required.

Q: What is the significance of the wettable flank feature on PESD5V0S1ULD,315? A: Wettable flank construction improves solder joint visibility and reliability during automated optical inspection (AOI) in manufacturing processes. This feature does not affect electrical performance or circuit functionality.

Q: Why does PESD5V0U1UL,315 have missing clamping voltage and peak pulse current specifications? A: The provided data sheet information for this part does not include these parameters. Verification with the manufacturer's complete technical documentation is necessary before selection for applications requiring specific clamping or current ratings.

Q: Is CPDQC5V0USP-HF a direct replacement for ACPDQC5V0USP-HF? A: Yes. Both parts are manufactured by Comchip Technology with identical electrical specifications, package type (SOD-923), and automotive qualification (AEC-Q101). The primary difference is higher inventory availability for CPDQC5V0USP-HF.

Q: How do operating temperature ranges affect substitute selection? A: ACPDQC5V0USP-HF does not specify an operating temperature range in the provided data. Nexperia parts support -55°C to 150°C (TA), while SP3031-01ETG supports -40°C to 125°C (TJ). Application temperature requirements must be confirmed before final selection.

Q: Can multiple substitute parts be used interchangeably in the same design? A: No. Each substitute part has distinct electrical characteristics (clamping voltage, peak pulse current, capacitance). Circuit design validation is required for each specific part number before production implementation.
