CPDF5V0U-HF Equivalent & Substitute Parts

Part Overview

The CPDF5V0U-HF is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection applications. This surface-mount component operates with a 5V reverse standoff voltage and provides 12.5V maximum clamping voltage at peak pulse current. The part is currently active in production and widely available in inventory (809 pcs in stock). Substitute parts are identified when electrical characteristics, mechanical packaging, and compliance certifications remain equivalent across the component family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CPDF5V0U-HF is determined by strict equivalence across the following critical parameters:

• Voltage rating class (5V reverse standoff, 6V minimum breakdown, 12.5V maximum clamping)
• Peak pulse current capacity (16A at 8/20µs)
• Peak pulse power dissipation (200W)
• Unidirectional channel configuration (single channel)
• Surface-mount package specification (1005/SOD-323F)
• Compliance certifications (ROHS3, REACH Unaffected)
• Manufacturer consistency (Comchip Technology)

The CPDF5V0U part number represents the direct equivalent within the same product family, differing only in packaging designation suffix. Both parts share identical electrical performance characteristics and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CPDF5V0U-HF and CPDF5V0U are active production components from Comchip Technology with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. The CPDF5V0U variant offers higher stock levels (2780 pcs versus 809 pcs), which may provide supply chain advantages for high-volume applications. Both parts maintain full ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across global markets. The 1005/SOD-323F package specification is consistent across both variants, guaranteeing PCB layout and assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Can CPDF5V0U be used as a direct replacement for CPDF5V0U-HF?

A: Yes. Both parts are electrically and mechanically equivalent. The difference in part number suffix reflects packaging designation only. All critical parameters—voltage ratings, peak pulse current, power dissipation, and package dimensions—are identical.

Q: What does the "-HF" suffix indicate in CPDF5V0U-HF?

A: The "-HF" suffix denotes a specific packaging or distribution designation from Comchip Technology. The base electrical component (CPDF5V0) remains unchanged between CPDF5V0U-HF and CPDF5V0U variants.

Q: Are there any compliance differences between these parts?

A: No. Both CPDF5V0U-HF and CPDF5V0U maintain identical ROHS3 compliance and REACH Unaffected status. Moisture sensitivity level (MSL 1 - Unlimited) is consistent across both variants.

Q: Will the 1005/SOD-323F package fit the same PCB footprint for both parts?

A: Yes. The package specification is identical for both CPDF5V0U-HF and CPDF5V0U. PCB layout, solder pad dimensions, and assembly processes remain unchanged.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain lead times. The CPDF5V0U currently has higher stock availability (2780 pcs).

Q: Are there any electrical performance differences between these parts?

A: No. Voltage ratings (5V standoff, 6V breakdown, 12.5V clamping), peak pulse current (16A), power dissipation (200W), and capacitance (90pF @ 1MHz) are identical across both variants.
