Substitute Part Grouping Explanation

Substitute parts for the 5KP6.5AE3/TR13 are classified into two functional groups based on electrical parameter compatibility and packaging considerations:

Group 1: Direct Electrical Equivalents (P600 Package) Parts that maintain identical reverse standoff voltage (6.5V), breakdown voltage (7.22V minimum), clamping voltage (11.2V maximum), and 5000W peak pulse power rating. These parts operate within the same electrical performance envelope and are suitable for direct replacement in applications requiring P600 axial through-hole mounting.

Group 2: Voltage-Compatible Alternatives (Reduced Power Rating) Parts that maintain the 6.5V reverse standoff voltage and 11.2V clamping voltage but feature reduced peak pulse current (100A) and power dissipation (1500W). These parts are suitable for applications with lower transient energy requirements and are available in alternative package configurations (DO-201).

Group 3: Voltage-Offset Alternatives (Higher Standoff Voltage) Parts with elevated reverse standoff voltage (7.0V) and clamping voltage (12V maximum), available in DO-201 package configuration. These parts are suitable for applications requiring higher voltage protection thresholds.

Group 4: Lower Voltage Alternatives (Reduced Standoff Voltage) Parts with reduced reverse standoff voltage (5.8V) and lower clamping voltage (13.4V maximum), available in DO-15 package configuration. These parts are suitable for lower voltage protection applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 5KP6.5A (Littelfuse Inc.)

The 5KP6.5A represents the closest electrical equivalent to the 5KP6.5AE3/TR13. Both devices share identical reverse standoff voltage (6.5V), breakdown voltage (7.22V minimum), clamping voltage (11.2V maximum), and peak pulse power rating (5000W). The 5KP6.5A delivers marginally higher peak pulse current (455.4A versus 446A), providing equivalent or superior transient suppression performance. Both parts maintain P600 axial through-hole packaging, identical operating temperature range (-55 to 175°C), and full RoHS3 compliance. This substitute is suitable for direct replacement in applications where P600 package compatibility is required.

Secondary Substitute: LCE6.5A (Littelfuse Inc.)

The LCE6.5A maintains identical voltage parameters (6.5V reverse standoff, 7.22V breakdown minimum, 11.2V clamping maximum) and operating temperature range (-55 to 175°C) with full RoHS3 compliance. However, this device features reduced peak pulse current (100A) and power dissipation (1500W), representing a lower-energy variant. The LCE6.5A is packaged in DO-201 configuration rather than P600, requiring PCB layout modification. This substitute is appropriate for applications with lower transient energy requirements or where DO-201 package compatibility exists.

Tertiary Substitute: LCE7.0A (Littelfuse Inc.)

The LCE7.0A provides voltage-offset protection with elevated reverse standoff voltage (7.0V) and clamping voltage (12V maximum). This device maintains identical peak pulse current (100A) and power dissipation (1500W) as the LCE6.5A, with identical operating temperature range and RoHS3 compliance. The LCE7.0A is packaged in DO-201 configuration. This substitute is suitable for applications requiring higher voltage protection thresholds or where DO-201 package compatibility exists.

Alternative Substitute: P6KE6V8A (Fairchild Semiconductor)

The P6KE6V8A features reduced reverse standoff voltage (5.8V) and lower peak pulse current (298A at 8/20µs pulse width) with significantly reduced power dissipation (600W). This device is packaged in DO-15 configuration and does not specify operating temperature range or RoHS compliance status. The P6KE6V8A is suitable only for applications with lower voltage protection requirements and lower transient energy budgets where DO-15 package compatibility exists.

Frequently Asked Questions (FAQ)

Q: Can the 5KP6.5A (Littelfuse) be used as a direct replacement for the 5KP6.5AE3/TR13 (Microchip)?

A: Yes. Both devices share identical electrical specifications: 6.5V reverse standoff voltage, 7.22V minimum breakdown voltage, 11.2V maximum clamping voltage, and 5000W peak pulse power rating. Both are packaged in P600 axial through-hole configuration with identical operating temperature range (-55 to 175°C) and RoHS3 compliance. The 5KP6.5A is a direct electrical and mechanical equivalent.

Q: What is the primary difference between the 5KP6.5A and the LCE6.5A?

A: The primary differences are package configuration and power handling capacity. The 5KP6.5A uses P600 axial packaging with 5000W peak pulse power and 446-455A peak pulse current. The LCE6.5A uses DO-201 axial packaging with reduced 1500W peak pulse power and 100A peak pulse current. Both maintain identical voltage parameters (6.5V reverse standoff, 11.2V clamping). Selection depends on application transient energy requirements and PCB package compatibility.

Q: Can the LCE7.0A be substituted for the 5KP6.5AE3/TR13?

A: The LCE7.0A is not a direct substitute due to elevated voltage parameters. The LCE7.0A features 7.0V reverse standoff voltage and 12V maximum clamping voltage compared to 6.5V and 11.2V respectively for the 5KP6.5AE3/TR13. Additionally, the LCE7.0A provides reduced power handling (1500W versus 5000W). The LCE7.0A is suitable only for applications designed for higher voltage protection thresholds.

Q: What package configurations are available among the substitute parts?

A: Three package configurations are represented: P600 axial (5KP6.5AE3/TR13 and 5KP6.5A), DO-201 axial (LCE6.5A and LCE7.0A), and DO-15 axial (P6KE6V8A). Package selection depends on PCB layout design and mounting requirements. P600 and DO-201 packages are larger and accommodate higher current handling. DO-15 is the smallest package with reduced current capacity.

Q: Are all substitute parts RoHS3 compliant?

A: The 5KP6.5A, LCE6.5A, and LCE7.0A are confirmed RoHS3 compliant. The P6KE6V8A does not specify RoHS compliance status in the provided data. Compliance verification is required before selecting the P6KE6V8A for applications with RoHS requirements.

Q: What is the difference between the 10/1000µs and 8/20µs pulse width specifications?

A: The 10/1000µs pulse width is the standard specification for TVS diodes in most industrial and telecommunications applications. The 8/20µs pulse width is an alternative specification sometimes used for specific surge protection standards. The 5KP6.5AE3/TR13, 5KP6.5A, LCE6.5A, and LCE7.0A use 10/1000µs specification. The P6KE6V8A uses 8/20µs specification. Pulse width selection depends on application surge standard requirements.

Q: Can the P6KE6V8A be used in place of the 5KP6.5AE3/TR13?

A: The P6KE6V8A is not recommended as a substitute for the 5KP6.5AE3/TR13. The P6KE6V8A features significantly lower reverse standoff voltage (5.8V versus 6.5V), reduced peak pulse current (298A versus 446A), and substantially lower power dissipation (600W versus 5000W). Additionally, operating temperature range is not specified, and RoHS compliance status is not confirmed. The P6KE6V8A is suitable only for lower voltage, lower energy applications.

Q: What inventory availability exists for substitute parts?

A: Current inventory levels are: 5KP6.5A (2600 pcs), LCE6.5A (1053 pcs), LCE7.0A (1366 pcs), and P6KE6V8A (19200 pcs). The 5KP6.5AE3/TR13 original part has 769 pcs in stock. Inventory levels should be verified with suppliers for current availability and lead time requirements.
