Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPDTR035V0C-HF is determined by the following critical electrical and mechanical parameters:

• Voltage Rating Compatibility: Reverse standoff voltage of 5V (typical) with breakdown voltage minimum of 6.1V
• Bidirectional Protection: 2-channel bidirectional TVS diode configuration
• Package Compatibility: Surface-mount SOT-23 family packaging (SOT-23-3 or equivalent 3-lead configurations)
• Zener Diode Type: Silicon Zener-based TVS technology
• Application Class: General-purpose transient voltage suppression

The CDSOT23-0502B from Bourns Inc. satisfies all substitution criteria through matching voltage ratings, bidirectional channel configuration, and compatible surface-mount packaging. This part is currently in active production status with established supply availability.

Parameter Comparison

Engineering Selection Recommendations

The CDSOT23-0502B is the qualified substitute for the obsolete CPDTR035V0C-HF based on the following factors:

• Product Status: The substitute part is in active production, ensuring long-term availability and supply chain stability, whereas the main part is obsolete.
• Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 export classification, ensuring equivalent compliance posture.
• Electrical Equivalence: Matching 5V reverse standoff voltage and 2-channel bidirectional configuration provide direct functional replacement in general-purpose TVS applications.
• Package Compatibility: SOT-23-3 packaging is mechanically and electrically compatible with SOT-23F footprints in standard surface-mount PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the CDSOT23-0502B directly replace the CPDTR035V0C-HF on existing PCBs?

A: Yes. Both parts share the same 5V reverse standoff voltage rating, 2-channel bidirectional configuration, and compatible SOT-23 family packaging. PCB footprints designed for SOT-23F accommodate SOT-23-3 components without modification.

Q: What are the key differences between these parts?

A: The CDSOT23-0502B provides additional specified parameters including 9V clamping voltage and 8.5A peak pulse current, which were not specified for the obsolete CPDTR035V0C-HF. The substitute part is in active production with established supply availability.

Q: Are there compliance or certification differences?

A: No. Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring equivalent regulatory standing for procurement and export purposes.

Q: Why is the CPDTR035V0C-HF obsolete?

A: The main part is classified as obsolete by the manufacturer. The CDSOT23-0502B from Bourns Inc. is the recommended substitute, offering equivalent electrical performance with active production status.

Q: What packaging options are available for the substitute part?

A: The CDSOT23-0502B is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production-volume procurement.
