Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP8.0A-E3/54 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 8V
• Voltage - Breakdown (Min): 8.89V
• Voltage - Clamping (Max) @ Ipp: 13.6V (primary criterion; 15V variant acceptable with design verification)
• Current - Peak Pulse (10/1000µs): 368A minimum
• Power - Peak Pulse: 5000W (5kW)
• Mounting Type: Through Hole
• Package / Case: P600 or R-6 Axial
• Type: Zener, Unidirectional
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories:

Category A - Direct Electrical Equivalents (13.6V Clamping):

• 5KP8.0A (Littelfuse Inc., Cut Tape)
• 5KP8.0AE3/TR13 (Microchip Technology, Tape & Reel)
• 5KP8.0A-B (Littelfuse Inc., Bulk)
• 5KP8.0A-HR (Littelfuse Inc., Tape & Reel)
• 5KP8.0A-HRA (Littelfuse Inc., Tape & Reel)

Category B - Electrical Variant (15V Clamping):

• 5KP8.0E3/TR13 (Microchip Technology, Tape & Reel)

Category A parts maintain identical electrical specifications and are interchangeable at the component level. Category B presents a higher clamping voltage (15V vs. 13.6V) and lower peak pulse current (333A vs. 368A), requiring circuit-level evaluation before substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

The 5KP8.0A (Littelfuse Inc.) in Cut Tape packaging is the recommended primary substitute. This part maintains identical electrical specifications, is in active production status, and offers the highest inventory availability (3300 pcs). All Category A substitutes—5KP8.0AE3/TR13, 5KP8.0A-B, 5KP8.0A-HR, and 5KP8.0A-HRA—are electrically equivalent and ROHS3 compliant, differing only in packaging format and distribution channel.

Secondary Substitute (Electrical Variant):

The 5KP8.0E3/TR13 (Microchip Technology) presents a 15V clamping voltage versus the 13.6V specification of the original part. This variant is suitable only when circuit design permits higher transient voltage clamping and can tolerate the reduced peak pulse current specification (333A vs. 368A). This part requires explicit design verification before implementation.

Package Considerations:

The 5KP8.0A-G (Comchip Technology) uses an R-6 axial package instead of the standard P600. While electrically compatible, mechanical fit verification is required for PCB layouts designed for P600 package dimensions. Additionally, this variant specifies a maximum operating temperature of 150°C versus 175°C for other substitutes, which may be limiting in high-temperature applications.

Compliance and Production Status:

All active substitutes maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity), ensuring compatibility with modern manufacturing and environmental standards. The obsolete status of the original part necessitates transition to one of the active alternatives for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use 5KP8.0A-E3/TR13 (Microchip) as a direct replacement for 5KP8.0A-E3/54 (Vishay)?

A: Yes. The 5KP8.0AE3/TR13 maintains identical electrical specifications: 8V reverse standoff, 8.89V breakdown minimum, 13.6V clamping maximum, and 368A peak pulse current. The primary difference is packaging format (Tape & Reel vs. original specification) and active production status. Verify that your procurement and assembly processes accommodate the Tape & Reel format.

Q: What is the difference between 5KP8.0A-B and 5KP8.0A-HR?

A: Both parts are manufactured by Littelfuse and are electrically identical. The difference is packaging: 5KP8.0A-B is supplied in Bulk format, while 5KP8.0A-HR is supplied in Tape & Reel format. Select based on your assembly process requirements and order quantities.

Q: Can I substitute the 5KP8.0E3/TR13 (15V clamping) for the original 5KP8.0A-E3/54 (13.6V clamping)?

A: Substitution is possible only with circuit-level design verification. The higher clamping voltage (15V vs. 13.6V) and lower peak pulse current (333A vs. 368A) may affect transient suppression performance. Evaluate whether your protected circuit can tolerate the higher voltage transient and whether the reduced current capacity meets your application requirements.

Q: Is the 5KP8.0A-G (Comchip, R-6 package) compatible with my PCB layout designed for P600 package?

A: The R-6 and P600 packages are both axial through-hole formats but have different physical dimensions. Mechanical compatibility depends on your PCB layout spacing and hole positioning. Verify package dimensions against your design before substitution. Additionally, note that this variant specifies a maximum operating temperature of 150°C, which may be restrictive for high-temperature applications.

Q: Why is the original 5KP8.0A-E3/54 marked as obsolete?

A: Obsolescence indicates that Vishay General Semiconductor - Diodes Division has discontinued production of this specific part number. Active substitutes from Littelfuse, Microchip, and Comchip provide equivalent or compatible functionality and are recommended for new designs and ongoing procurement.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity), ensuring compatibility with modern manufacturing standards and environmental regulations.

Q: What packaging options are available for the 5KP8.0A equivalent?

A: The 5KP8.0A equivalent is available in multiple packaging formats: Cut Tape (CT), Bulk, Tape & Box (TB), and Tape & Reel (TR). Select based on your procurement volume, assembly process, and inventory management requirements.
