Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB20CA-M3/52 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 17.1V
• Voltage - Breakdown (Min): 19V
• Voltage - Clamping (Max) @ Ipp: 27.7V
• Current - Peak Pulse (10/1000µs): 21.7A
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Surface Mount
• Package / Case: DO-214AA, SMB

The P6SMB20CA manufactured by Eaton - Electronics Division meets all critical electrical parameters and maintains the same package designation. This part qualifies as a direct substitute based on identical voltage ratings, current handling, power dissipation, and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the P6SMB20CA-M3/52 (Vishay) and P6SMB20CA (Eaton) are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts may be based on:

Thermal Operating Range: The Vishay part supports -65°C to 150°C, while the Eaton part supports -55°C to 150°C. Applications requiring operation below -55°C junction temperature require the Vishay variant.

Packaging Format: The Vishay part is supplied in Tape & Box (TB) format, while the Eaton part is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly line requirements and inventory management practices.

Availability: Both parts maintain active inventory status. The Eaton P6SMB20CA shows higher stock availability (35,400 pcs) compared to the Vishay P6SMB20CA-M3/52 (916 pcs).

All electrical and mechanical parameters remain identical across both options, ensuring functional interchangeability within the specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB20CA (Eaton) directly replace the P6SMB20CA-M3/52 (Vishay)?

A: Yes, the Eaton P6SMB20CA is a direct electrical and mechanical substitute. Both parts share identical voltage ratings (17.1V standoff, 27.7V clamping), current handling (21.7A peak pulse), power dissipation (600W), and package designation (DO-214AA, SMB). The primary difference is the operating temperature range: Vishay supports -65°C to 150°C while Eaton supports -55°C to 150°C. Applications operating above -55°C junction temperature can use either part interchangeably.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching: reverse standoff voltage (17.1V), breakdown voltage minimum (19V), clamping voltage maximum (27.7V), peak pulse current (21.7A), peak pulse power (600W), package type (DO-214AA, SMB), and bidirectional channel configuration (1 channel). Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Are there packaging considerations when switching between suppliers?

A: Yes. The Vishay P6SMB20CA-M3/52 is supplied in Tape & Box (TB) format, while the Eaton P6SMB20CA is supplied in Cut Tape (CT) & Digi-Reel® format. Verify that your assembly equipment and procurement processes support the packaging format of the selected substitute part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Vishay P6SMB20CA-M3/52 and Eaton P6SMB20CA are RoHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1). Both parts meet ECCN EAR99 and HTSUS 8541.10.0080 classifications.

Q: Which part should be selected for low-temperature applications?

A: For applications requiring operation below -55°C junction temperature, the Vishay P6SMB20CA-M3/52 is required, as it supports -65°C minimum operating temperature. The Eaton P6SMB20CA is limited to -55°C minimum.
