Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PESD2CAN,215 is determined by the following critical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff: 24V nominal
• Voltage - Breakdown (Min): 26.2V
• Bidirectional channels: 2
• Package / Case: SOT-23-3 compatible
• Mounting Type: Surface Mount
• Applications: CAN bus protection

Secondary Compatibility Factors:

• Voltage - Clamping (Max) @ Ipp: 40V to 43V range acceptable
• Current - Peak Pulse (8/20µs): 5A minimum
• Operating Temperature: -40°C to -55°C minimum, 150°C maximum
• RoHS3 and REACH compliance required
• AEC-Q101 qualification preferred for automotive applications

Parts meeting these criteria are classified as direct substitutes. The CPDT-5V0C-HF operates at a different voltage class (5V) and is not a direct substitute for CAN bus applications; it is listed as a cross-reference only.

Parameter Comparison

Engineering Selection Recommendations

ESDCAN24-2BLY (STMicroelectronics) is the primary recommended substitute. This part maintains identical voltage specifications (24V standoff, 26.2V breakdown), equivalent clamping voltage (40V vs. 41V), and meets or exceeds current handling (5.5A vs. 5A). It carries active product status, AEC-Q101 automotive qualification, and identical RoHS3/REACH compliance. Operating temperature range is -40°C to 150°C, which covers standard automotive applications. Peak pulse power rating matches at 230W.

CDSOT23-T24CAN (Bourns Inc.) provides an alternative with superior current handling (8A vs. 5A) and lower capacitance (22pF vs. 25pF), beneficial for high-speed CAN applications. Voltage parameters are identical. This part is active and RoHS3 compliant but lacks published AEC-Q101 qualification and automotive grade designation. Operating temperature minimum is -40°C.

PEC3324C2A-AU_R1_000A1 (Panjit International Inc.) offers the widest operating temperature range (-55°C to 150°C) matching the original part, with higher current capacity (7A) and AEC-Q101 qualification. Clamping voltage is slightly elevated at 43V. This part is active and automotive-qualified, suitable for extended temperature applications.

For CAN bus protection requiring continued manufacturing support and automotive qualification, ESDCAN24-2BLY is the preferred direct substitute. CDSOT23-T24CAN is suitable for applications prioritizing higher current capacity. PEC3324C2A-AU_R1_000A1 is appropriate for extended temperature range requirements.

Frequently Asked Questions (FAQ)

Q: Can CDSOT23-T24CAN replace PESD2CAN,215 in automotive CAN bus circuits?

A: CDSOT23-T24CAN meets the core electrical requirements for CAN bus protection with identical voltage specifications and superior current handling. However, it lacks published AEC-Q101 qualification. For automotive applications requiring formal qualification documentation, ESDCAN24-2BLY or PEC3324C2A-AU_R1_000A1 are preferred.

Q: What is the difference between the clamping voltages (40V, 41V, 43V) across these parts?

A: All clamping voltages fall within acceptable operating margins for CAN bus protection. The 1-3V variation does not affect circuit functionality. Selection should be based on system transient voltage tolerance specifications and the substitute part's other performance characteristics.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts are available in SOT-23-3 surface mount packages compatible with PESD2CAN,215 PCB layouts. No board redesign is required for mechanical compatibility.

Q: Why is CPDT-5V0C-HF listed if it cannot replace PESD2CAN,215?

A: CPDT-5V0C-HF operates at 5V nominal voltage and is designed for general-purpose ESD protection, not CAN bus applications. It is included as a cross-reference only and is not a functional substitute for 24V CAN bus circuits.

Q: Which substitute offers the best thermal performance?

A: PEC3324C2A-AU_R1_000A1 supports the widest operating temperature range (-55°C to 150°C), matching the original PESD2CAN,215. ESDCAN24-2BLY and CDSOT23-T24CAN operate from -40°C minimum. Selection depends on system thermal requirements.

Q: Do all substitutes meet RoHS3 and REACH compliance?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the environmental compliance of PESD2CAN,215.
