Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA100A is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 85.5V
• Voltage - Breakdown (Min): 95V
• Voltage - Clamping (Max) @ Ipp: 137V
• Current - Peak Pulse (10/1000µs): 3A
• Power - Peak Pulse: 400W
• Unidirectional Channels: 1
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C (TJ)

The substitute part identified maintains identical electrical specifications and mechanical compatibility. Both the original Bourns Inc. part and the Eaton - Electronics Division equivalent share the same base product number (P4SMA) and deliver equivalent performance characteristics for transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns Inc. P4SMA100A and the Eaton - Electronics Division P4SMA100A are active production components with full regulatory compliance. The Bourns part carries RoHS3 certification, while the Eaton equivalent is RoHS compliant. Both components are REACH affected and classified under ECCN EAR99. Selection between these parts may be based on supplier availability, lead time, inventory position, or established procurement agreements. No technical performance differentiation exists between the two options for the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the Eaton P4SMA100A directly replace the Bourns P4SMA100A in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters, including voltage ratings, current capacity, temperature range, and package configuration. Direct substitution is supported without design modification.

Q: Are there differences in RoHS compliance between these parts?

A: The Bourns part is RoHS3 compliant, while the Eaton part is RoHS compliant. Both meet regulatory requirements for their respective certifications. Verify compliance requirements for your specific application and region.

Q: What is the significance of the DO-214AC (SMA) package designation?

A: DO-214AC and SMA are equivalent designations for the same surface mount package. Both parts use this standardized package, ensuring identical PCB footprint, land pattern, and mounting compatibility.

Q: Are there application differences between the Bourns and Eaton versions?

A: The Bourns part is specified for general purpose applications, while the Eaton part is specified for telecom applications. Both deliver identical electrical performance and can be used interchangeably based on electrical requirements alone.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures.
