LCE13A Equivalent & Substitute Parts

Part Overview

The LCE13A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient protection applications. This through-hole component operates across a temperature range of -55°C to 175°C and is ROHS3 compliant. The part is currently in active production status with 920 units available in inventory. Alternative models may be required due to application-specific power handling requirements, packaging preferences, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The 5KP13A qualifies as a direct substitute for the LCE13A based on the following critical electrical parameters:

• Voltage - Reverse Standoff (Typ): 13V (identical)
• Voltage - Breakdown (Min): 14.4V (identical)
• Voltage - Clamping (Max) @ Ipp: 21.5V (identical)
• Unidirectional Channels: 1 (identical)
• Operating Temperature Range: -55°C to 175°C (identical)
• RoHS Status: ROHS3 Compliant (identical)

The 5KP13A differs in power handling capacity and packaging format, offering higher peak pulse current (237.2A vs. 70A) and greater peak pulse power (5000W vs. 1500W) within the same voltage protection envelope. Both components maintain identical voltage characteristics and thermal operating ranges, ensuring functional compatibility in protection circuits.

Parameter Comparison

Engineering Selection Recommendations

Both the LCE13A and 5KP13A are active production components from Littelfuse Inc. with identical ROHS3 and REACH compliance certifications. Selection between these parts depends on application power dissipation requirements. The LCE13A is suitable for applications with peak pulse currents up to 70A and 1500W power dissipation. The 5KP13A accommodates higher transient energy events with peak pulse currents up to 237.2A and 5000W power dissipation, while maintaining identical voltage protection characteristics. Both components operate across the full -55°C to 175°C temperature range and are classified as MSL 1 (unlimited moisture sensitivity).

Frequently Asked Questions (FAQ)

Q: Can the 5KP13A replace the LCE13A in existing designs?

A: Yes. Both components provide identical voltage protection characteristics (13V standoff, 21.5V clamping). The 5KP13A offers higher current and power handling capacity, making it suitable for applications requiring greater transient energy absorption.

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

A: The LCE13A handles peak pulse currents of 70A at 1500W, while the 5KP13A handles 237.2A at 5000W. Voltage protection parameters remain identical across both components.

Q: Are there package compatibility considerations?

A: The LCE13A uses DO-201AA packaging, while the 5KP13A uses P600 packaging. Both are through-hole axial components. PCB layout and footprint verification is required when substituting between different package types.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LCE13A and 5KP13A are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited). Both operate across -55°C to 175°C.

Q: Which part should be selected for new designs?

A: Selection is based on application transient energy requirements. For applications with peak pulse currents exceeding 70A or power dissipation exceeding 1500W, the 5KP13A is the appropriate choice. For lower energy transients, the LCE13A is suitable.
