Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4KE110CA-B are identified based on strict electrical and mechanical parameter compatibility. The primary substitution criteria are:

Critical Parameters for Substitution:

• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Grouping Logic:

Group 1 - Direct Equivalent (Identical Electrical & Mechanical Parameters): P4KE110CA (Taiwan Semiconductor Corporation) maintains all critical electrical parameters and operates in the same DO-204AL package. Packaging differs (Tape & Reel vs. Bulk), but electrical performance and mechanical fit are identical.

Group 2 - Higher Current Rating Substitute (Enhanced Pulse Handling): P6KE110CA (Taiwan Semiconductor Corporation) maintains all critical voltage parameters (94V standoff, 105V breakdown, 152V clamping) but operates in the DO-15 package with increased peak pulse current (4A vs. 2.7A) and higher peak pulse power (600W vs. 400W). This substitute is suitable for applications requiring higher transient current handling while maintaining identical voltage protection characteristics.

Parameter Comparison

Engineering Selection Recommendations

P4KE110CA (Direct Equivalent): Select this substitute when procurement requires an alternative source from Taiwan Semiconductor Corporation while maintaining identical electrical specifications and mechanical compatibility. Both parts are active products with ROHS3 compliance. The primary difference is packaging format (Tape & Reel vs. Bulk), which does not affect electrical performance or circuit board integration.

P6KE110CA (Enhanced Current Rating): Select this substitute for applications requiring higher transient current handling capacity. The P6KE110CA provides 4A peak pulse current versus 2.7A in the main part, with proportionally increased power dissipation (600W vs. 400W). All voltage protection parameters remain identical. Package change from DO-204AL to DO-15 requires PCB layout verification for mechanical fit. Both parts are active products with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can P4KE110CA replace P4KE110CA-B directly? A: Yes. Both parts maintain identical electrical parameters (94V standoff, 105V breakdown, 152V clamping, 2.7A peak pulse) and operate in the same DO-204AL package. The difference is packaging format (Tape & Reel vs. Bulk), which does not affect circuit performance or PCB mounting.

Q: When should P6KE110CA be used instead of P4KE110CA-B? A: Use P6KE110CA when the application requires higher transient current handling. The P6KE110CA provides 4A peak pulse current (versus 2.7A) and 600W peak pulse power (versus 400W). Voltage protection characteristics remain identical. Verify PCB layout compatibility with the DO-15 package before substitution.

Q: Are all substitute parts RoHS3 compliant? A: Yes. P4KE110CA and P6KE110CA are both ROHS3 compliant, matching the compliance status of the main part P4KE110CA-B.

Q: What is the difference between DO-204AL and DO-15 packages? A: Both are through-hole axial packages for TVS diodes. DO-204AL (DO-41) and DO-15 differ in physical dimensions and lead spacing. Verify PCB footprint compatibility before selecting P6KE110CA as a substitute.

Q: Are all substitute parts actively produced? A: Yes. P4KE110CA and P6KE110CA are both active products, ensuring ongoing availability and supply chain continuity.
