LCE8.0A Equivalent & Substitute Parts

Part Overview

The LCE8.0A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse, designed for general-purpose transient protection applications. This through-hole component operates across a temperature range of -55°C to 175°C and maintains an active product status. Alternative models may be required due to inventory constraints, application-specific power handling requirements, or packaging preferences in system design.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LCE8.0A is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 8V
• Voltage - Breakdown (Min): 8.89V
• Voltage - Clamping (Max) @ Ipp: 13.6V
• Type: Zener, Unidirectional
• Operating Temperature Range: -55°C to 175°C (TJ)
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

The 5KP8.0A qualifies as a direct substitute based on matching voltage specifications, temperature range, and compliance certifications. Differences in peak pulse current (375A vs. 100A) and power dissipation (5000W vs. 1500W) represent enhanced performance characteristics that maintain full compatibility while providing increased transient protection capability.

Parameter Comparison

Engineering Selection Recommendations

Both the LCE8.0A and 5KP8.0A maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between these components should be based on application-specific transient energy requirements. The LCE8.0A is suitable for general-purpose applications with moderate transient pulse energy. The 5KP8.0A provides enhanced peak pulse current handling (375A vs. 100A) and power dissipation (5000W vs. 1500W), making it appropriate for applications requiring higher transient protection margins or repeated high-energy pulse events. Both components are through-hole mounted with identical voltage specifications and operating temperature ranges, ensuring functional interchangeability within the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5KP8.0A directly replace the LCE8.0A in existing designs?

A: Yes. Both components share identical voltage specifications (8V reverse standoff, 8.89V breakdown minimum, 13.6V clamping maximum), operating temperature range (-55°C to 175°C), and compliance certifications. The 5KP8.0A provides higher peak pulse current and power dissipation ratings, which do not compromise compatibility.

Q: What is the primary difference between these two parts?

A: The 5KP8.0A offers enhanced transient protection capability with 375A peak pulse current and 5000W power dissipation compared to the LCE8.0A's 100A and 1500W ratings. Both maintain identical voltage clamping characteristics.

Q: Are the package types interchangeable?

A: Both components use axial through-hole mounting. The LCE8.0A uses DO-201AA/DO-27 packaging, while the 5KP8.0A uses P600 packaging. Physical dimensions and lead spacing may differ; verify PCB layout compatibility before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the LCE8.0A and 5KP8.0A are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (unlimited moisture sensitivity level).

Q: Which part should be selected for new designs?

A: Selection depends on transient energy requirements. For applications with moderate transient pulses, either part is suitable. For applications requiring higher transient protection margins or experiencing repeated high-energy events, the 5KP8.0A is the appropriate choice.
