Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP7.0AE3/TR13 is determined by the following critical parameters:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Clamping (Max) @ Ipp: 12V
• Type: Zener, Unidirectional
• Operating Temperature Range: -55°C to 175°C
• Mounting Type: Through Hole
• RoHS3 Compliance

Secondary Compatibility Factors:

• Current - Peak Pulse (10/1000µs): 417A nominal
• Power - Peak Pulse: 5000W nominal
• Package configuration: P600 axial or equivalent through-hole axial packages

Substitute parts are grouped into two categories based on electrical performance alignment:

Category A - Full Electrical Equivalents (P600 Package): Parts maintaining identical voltage specifications, peak pulse current ratings within 2% tolerance, and 5000W power dissipation in P600 axial packaging.

Category B - Functional Equivalents (Alternative Packages): Parts matching voltage specifications and operating temperature range but with reduced peak pulse current ratings and alternative through-hole axial package configurations (DO-201).

Parameter Comparison

Engineering Selection Recommendations

5KP7.0A (Littelfuse Inc.) - Primary Substitute

The 5KP7.0A represents a direct electrical equivalent to the 5KP7.0AE3/TR13. Both devices share identical voltage specifications (7V reverse standoff, 12V clamping), matching peak pulse current ratings (417A vs. 425A, within 2% tolerance), and equivalent 5000W power dissipation in P600 axial packaging. Both maintain Active product status, ROHS3 compliance, and unlimited MSL rating. The primary distinction is packaging format: 5KP7.0A is supplied on cut tape (CT) rather than tape and reel (TR). This substitute is suitable for applications requiring identical electrical performance and mechanical compatibility.

LCE7.0A (Littelfuse Inc.) - Functional Equivalent

The LCE7.0A matches the 5KP7.0AE3/TR13 in voltage specifications (7V reverse standoff, 12V clamping) and operating temperature range. However, this device operates at reduced peak pulse current (100A) and power dissipation (1500W), representing a 76% reduction in transient handling capacity. The LCE7.0A is packaged in DO-201AA/DO-27 axial configuration rather than P600. This substitute is applicable only in applications where peak pulse current requirements do not exceed 100A and where DO-201 package dimensions are mechanically compatible with circuit board layout.

LCE6.5A (Littelfuse Inc.) - Limited Functional Equivalent

The LCE6.5A provides reduced voltage specifications (6.5V reverse standoff, 11.2V clamping) compared to the 5KP7.0AE3/TR13, representing a 7% reduction in standoff voltage and 6.7% reduction in clamping voltage. Peak pulse current and power dissipation are similarly reduced to 100A and 1500W respectively. The DO-201 package configuration differs from P600. This substitute is applicable only in applications where lower voltage thresholds are acceptable and peak pulse current requirements do not exceed 100A.

All substitute parts maintain Active product status and full ROHS3 compliance, ensuring regulatory consistency with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 5KP7.0A be used as a direct replacement for the 5KP7.0AE3/TR13?

A: Yes. The 5KP7.0A is electrically equivalent with matching voltage specifications (7V reverse standoff, 12V clamping), peak pulse current (425A vs. 417A), and power dissipation (5000W). Both use P600 axial through-hole packaging. The primary difference is packaging format: 5KP7.0A is supplied on cut tape (CT) while the original is on tape and reel (TR). Circuit performance is identical.

Q: What are the limitations of using LCE7.0A as a substitute?

A: The LCE7.0A matches voltage specifications but operates at significantly reduced peak pulse current (100A vs. 417A) and power dissipation (1500W vs. 5000W). Additionally, the package is DO-201 rather than P600, requiring verification of mechanical compatibility with circuit board layout and component spacing. Use LCE7.0A only when transient pulse requirements do not exceed 100A peak current.

Q: Is the LCE6.5A suitable for applications requiring 7V protection?

A: No. The LCE6.5A has a 6.5V reverse standoff voltage, which is 0.5V lower than the 5KP7.0AE3/TR13. This voltage difference may result in premature device activation in circuits designed for 7V protection thresholds. Additionally, peak pulse current is limited to 100A. Use LCE6.5A only in applications where 6.5V standoff voltage is acceptable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 5KP7.0A, LCE7.0A, and LCE6.5A are all ROHS3 compliant with unlimited MSL rating (1), matching the compliance profile of the 5KP7.0AE3/TR13.

Q: What is the difference between P600 and DO-201 packaging?

A: P600 and DO-201 are both through-hole axial package configurations for diodes. P600 is a larger package format, while DO-201 (also designated DO-27) is a smaller alternative. Both are axial lead configurations suitable for through-hole mounting. Mechanical compatibility depends on circuit board layout, component spacing, and lead hole positioning. Verify package dimensions against PCB design specifications before substitution.

Q: Can packaging format (tape and reel vs. cut tape) affect circuit performance?

A: No. Packaging format (TR vs. CT) affects only component handling, storage, and assembly processes. Electrical and mechanical performance of the component itself is identical regardless of packaging format. Both 5KP7.0AE3/TR13 (TR) and 5KP7.0A (CT) deliver identical circuit performance.

Q: What should be verified before substituting with a lower-power device like LCE7.0A?

A: Before substituting with LCE7.0A, verify that the application's peak transient pulse current does not exceed 100A and that the total energy dissipation requirement does not exceed 1500W. Additionally, confirm that the DO-201 package dimensions are compatible with circuit board layout, component spacing, and thermal management requirements. The original 5KP7.0AE3/TR13 is rated for 417A peak current and 5000W power dissipation; LCE7.0A cannot handle these levels.
