Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP60CA-B is determined by the following critical parameters:

• Voltage - Reverse Standoff: 60V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 96.8V (exact match required)
• Current - Peak Pulse: 52.7A (exact match required)
• Power - Peak Pulse: 5000W (exact match required)
• Package / Case: P600, Axial (exact match required)
• Mounting Type: Through Hole (exact match required)
• Type: Zener, Bidirectional (exact match required)

The identified substitute parts maintain these electrical and mechanical specifications, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both 5KP60CA and SLD60-018-B meet the electrical and mechanical requirements for direct substitution with 5KP60CA-B. All three parts are ROHS3 compliant, REACH unaffected, and maintain identical core electrical specifications.

The 5KP60CA differs only in packaging format (Cut Tape versus Bulk), with no impact on electrical performance or circuit compatibility.

The SLD60-018-B is qualified to AEC-Q101 automotive standards and carries automotive-grade designation. This part is suitable for applications requiring automotive qualification. The voltage breakdown minimum specification is 68.4V compared to 66.7V in the 5KP60CA-B, remaining within acceptable operating parameters for the 60V standoff voltage class.

Selection between these substitutes should be based on packaging requirements and application-specific qualification needs.

Frequently Asked Questions (FAQ)

Q: Can 5KP60CA be used as a direct replacement for 5KP60CA-B?

A: Yes. Both parts share identical electrical specifications (60V standoff, 96.8V clamping, 52.7A peak pulse, 5000W power dissipation) and P600 axial through-hole packaging. The difference is packaging format: 5KP60CA is supplied in Cut Tape, while 5KP60CA-B is supplied in Bulk. Circuit performance is equivalent.

Q: What is the difference between 5KP60CA-B and SLD60-018-B?

A: Both parts meet the core electrical specifications for 60V TVS protection. SLD60-018-B carries AEC-Q101 automotive qualification and automotive-grade designation, making it suitable for automotive applications. The voltage breakdown minimum is 68.4V versus 66.7V, a difference that does not affect circuit compatibility at the 60V standoff rating. Both use P600 axial through-hole packaging.

Q: Are all three parts mechanically compatible?

A: Yes. All three parts use P600 axial through-hole packaging and are mounted identically on PCBs. No mechanical modifications are required when substituting between these parts.

Q: Do compliance certifications differ between these parts?

A: All three parts are ROHS3 compliant and REACH unaffected. SLD60-018-B additionally carries AEC-Q101 automotive qualification. For non-automotive applications, this additional certification does not affect performance.

Q: Which part should be selected for automotive applications?

A: SLD60-018-B is qualified to AEC-Q101 automotive standards. For automotive circuit designs, this part is the appropriate selection.
