Littelfuse P0080EC TVS Thyristor Equivalent & Substitute Parts

Part Overview

The Littelfuse P0080EC is a 6V off-state transient voltage suppressor (TVS) thyristor in the SIDACtor® series, rated for 400 A peak pulse current (8/20µs). This component is designed for transient overvoltage protection in electronic circuits. The P0080EC is currently classified as obsolete, making identification of compatible substitutes essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0080EC is determined by strict equivalence across the following critical parameters:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current ratings (both 8/20µs and 10/1000µs waveforms)
• Hold current (Ih)
• Capacitance
• Package and mounting configuration
• Number of active elements

The P0080ECL qualifies as a direct substitute because it maintains identical electrical specifications across all these parameters. Both parts are SIDACtor® series devices with matching TO-226-2 / TO-92-2 through-hole packaging.

Parameter Comparison

Engineering Selection Recommendations

The P0080ECL is the direct manufacturer-recommended substitute for the obsolete P0080EC. Both components are electrically and mechanically identical across all specified parameters.

Selection considerations:

• The P0080ECL carries active product status, ensuring ongoing availability and supply chain continuity.
• The P0080ECL meets ROHS3 compliance requirements, whereas the P0080EC is non-compliant. For applications subject to RoHS regulations, the P0080ECL is the required choice.
• Both parts are unaffected by REACH restrictions.
• Packaging is identical (TO-226-2 / TO-92-2 through-hole), permitting direct board-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the P0080ECL be used as a direct replacement for the P0080EC?

A: Yes. The P0080ECL is the manufacturer-recommended substitute. All electrical parameters (voltage ratings, current ratings, capacitance) and mechanical specifications (package, mounting type) are identical.

Q: What is the primary reason to transition from P0080EC to P0080ECL?

A: The P0080EC is obsolete. The P0080ECL is an active product with confirmed supply availability. Additionally, the P0080ECL meets ROHS3 compliance, whereas the P0080EC does not.

Q: Are there any differences in circuit behavior between these two parts?

A: No. Both parts are electrically equivalent. They have identical breakover voltage (25V), off-state voltage (6V), on-state voltage (4V), peak pulse current ratings (400A at 8/20µs, 100A at 10/1000µs), hold current (50mA), and capacitance (260pF).

Q: Can these parts be soldered into existing PCB designs without modification?

A: Yes. Both parts use the same TO-226-2 / TO-92-2 through-hole package. No PCB layout changes are required.

Q: What is the difference between the TO-226-2 and TO-92-2 package designations?

A: Both designations refer to the same physical package configuration used for this component. The part is compatible with standard through-hole assembly processes.

Q: Does the P0080ECL have any supply chain advantages over the P0080EC?

A: Yes. The P0080ECL is an active product with 1,342 units in stock, whereas the P0080EC is obsolete. The P0080ECL ensures long-term availability and supply reliability.
