Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6KE110C is determined by the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 94V — establishes the normal operating voltage threshold
• Voltage - Breakdown (Min): 99.45V — defines the minimum trigger voltage for protection activation
• Voltage - Clamping (Max) @ Ipp: 159.6V — specifies maximum voltage at peak pulse current
• Power - Peak Pulse: 600W — determines thermal dissipation capability
• Bidirectional Channels: 1 — confirms single-channel protection topology
• Package / Case: DO-204AC, DO-15, Axial — ensures mechanical and electrical compatibility
• Mounting Type: Through Hole — maintains board-level integration compatibility

The P6KE110CA from Taiwan Semiconductor Corporation meets these substitution criteria with equivalent electrical performance and identical package specifications.

Parameter Comparison

Engineering Selection Recommendations

The P6KE110CA qualifies as a direct substitute for the P6KE110C based on the following criteria:

• Both components maintain identical reverse standoff voltage (94V) and power dissipation rating (600W)
• Both are ROHS3 compliant, meeting environmental and regulatory requirements
• The P6KE110CA is currently in active production status, ensuring long-term availability and supply chain continuity
• Mechanical compatibility is confirmed through identical DO-15 axial through-hole packaging
• The P6KE110CA exhibits lower clamping voltage (152V vs. 159.6V) and higher breakdown voltage minimum (105V vs. 99.45V), providing enhanced protection margins in most general-purpose applications

Frequently Asked Questions (FAQ)

Q: Can the P6KE110CA directly replace the P6KE110C in existing designs?

A: Yes. Both components share identical reverse standoff voltage, power rating, and package specifications. The P6KE110CA is mechanically and electrically compatible for through-hole PCB integration.

Q: What is the significance of the clamping voltage difference between these parts?

A: The P6KE110CA exhibits a lower maximum clamping voltage (152V vs. 159.6V), which provides tighter voltage regulation during transient suppression events. This represents improved performance for general-purpose protection applications.

Q: Why is product status relevant to substitution?

A: The P6KE110C is obsolete, meaning Littelfuse has discontinued production. The P6KE110CA is in active production status, ensuring reliable procurement and consistent component availability for current and future manufacturing requirements.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant. The P6KE110CA additionally carries REACH Unaffected status, confirming compliance with European chemical regulations.

Q: Does packaging format affect substitution eligibility?

A: No. Both components use identical DO-15 axial through-hole packaging. The P6KE110CA is available in Tape & Reel format, which is standard for automated assembly processes and does not affect electrical or mechanical compatibility.
