Substitute Part Grouping Explanation
Substitution of the P6KE75CA-T is determined by strict equivalence across the following critical parameters:
- Voltage - Reverse Standoff (Typ): 64.1V ± tolerance
- Voltage - Clamping (Max) @ Ipp: 103V
- Current - Peak Pulse (10/1000µs): 5.8A minimum
- Power - Peak Pulse: 600W
- Mounting Type: Through Hole
- Package / Case: DO-15 or DO-204AC compatible
- Type: Zener, Bidirectional
Substitute parts are grouped by manufacturer and packaging configuration. All listed substitutes maintain electrical equivalence within the specified parameters. Packaging variants (Bulk, Tape & Reel, Cut Tape) represent the same electrical component with different distribution formats.

Engineering Selection Recommendations
All substitute parts listed maintain active product status with the exception of the original P6KE75CA-T, which is obsolete. Selection among active substitutes should prioritize parts with matching electrical specifications and compliance certifications.
Primary substitutes (P6KE75CA-AP, P6KE75CA-BP, P6KE75CA-TP, P6KE75CA-B, TP6KE75CA) provide direct electrical equivalence with ROHS3 compliance and identical or superior operating temperature ranges. These parts are suitable for direct replacement in existing designs.
Secondary substitutes (P6KE75CA from Diotec Semiconductor, P6KE75CAE3/TR13 from Microsemi Corporation) offer electrical equivalence with minor variations in peak pulse current (6.1A and 5.8A respectively) and operating temperature ranges. The Diotec part operates at -50°C minimum versus -55°C for the original; the Microsemi part operates to -65°C minimum but with a maximum temperature of 150°C versus 175°C.
Alternative substitute (SA64CA from Taiwan Semiconductor Corporation) provides functional equivalence with reduced peak pulse current (5A versus 5.8A) and reduced peak pulse power (500W versus 600W). This part is suitable only for applications where the lower current and power ratings are acceptable.
Packaging format selection (Bulk, Tape & Reel, Cut Tape, Axial) depends on procurement and assembly requirements and does not affect electrical performance.
Frequently Asked Questions (FAQ)
Q: Can I use SA64CA as a direct replacement for P6KE75CA-T?
A: SA64CA is functionally equivalent for overvoltage clamping but operates at reduced peak pulse current (5A versus 5.8A) and reduced peak pulse power (500W versus 600W). Use this part only if your application does not require the full current and power ratings of the original component.
Q: What is the difference between P6KE75CA-AP, P6KE75CA-BP, and P6KE75CA-TP?
A: These three parts from Micro Commercial Co are electrically identical. The suffix designates packaging format: -AP indicates Bulk packaging, -BP indicates Bulk packaging, and -TP indicates Cut Tape packaging. Select based on your procurement and assembly process requirements.
Q: Is P6KE75CAE3/TR13 compatible with the original P6KE75CA-T?
A: P6KE75CAE3/TR13 from Microsemi Corporation is electrically equivalent but uses Axial package format instead of DO-15. The operating temperature range differs slightly (-65°C to 150°C versus -55°C to 175°C). Verify mechanical fit in your PCB layout before selection.
Q: Why does the Diotec P6KE75CA show 6.1A peak pulse current instead of 5.8A?
A: The Diotec part specifies a higher peak pulse current (6.1A) while maintaining the same 600W power rating and 103V clamping voltage. This represents a tighter specification and is suitable for direct replacement.
Q: Are all substitute parts ROHS3 compliant?
A: ROHS3 compliance is confirmed for P6KE75CA-AP, P6KE75CA-BP, P6KE75CA-TP, P6KE75CA-B, TP6KE75CA, and SA64CA. The Diotec P6KE75CA and Microsemi P6KE75CAE3/TR13 do not specify ROHS3 status in the provided data. Verify compliance requirements for your application before selection.
Q: Can I substitute parts with different package formats?
A: Package format substitution (DO-15 to DO-204AC to Axial) requires mechanical verification. All three formats are electrically equivalent, but PCB layout, lead spacing, and mounting method differ. Confirm mechanical compatibility with your design before implementation.
