Littelfuse P2300EB TVS Thyristor Equivalent & Substitute Parts

Part Overview

The Littelfuse P2300EB is a 190V off-state, 250A peak pulse TVS thyristor in TO-226-2 packaging, part of the SIDACtor® series. This component is classified as obsolete, which necessitates identification of active equivalent parts for continued system design and maintenance applications. The P2300EB provides transient voltage suppression through a single-element thyristor configuration with 260V breakover voltage and 4V on-state voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2300EB is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

• Voltage - Breakover: 260V
• Voltage - Off State: 190V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 250A
• Current - Peak Pulse (10/1000µs): 80A
• Current - Hold (Ih): 150mA
• Number of Elements: 1
• Capacitance: 50pF
• Mounting Type: Through Hole
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)

The P2300EBL meets all electrical and mechanical specifications of the P2300EB and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The P2300EBL is the direct equivalent for the obsolete P2300EB. Both components share identical electrical specifications and mechanical packaging. The P2300EBL is currently in active production status with 20,400 units in stock, compared to the P2300EB's obsolete status with 2,400 units remaining.

The P2300EBL carries ROHS3 compliance, whereas the P2300EB is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the P2300EBL is the appropriate selection. For legacy systems without compliance mandates, both parts are electrically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the P2300EBL directly replace the P2300EB in existing designs?

A: Yes. The P2300EBL is electrically and mechanically identical to the P2300EB. Both components feature the same voltage ratings (260V breakover, 190V off-state, 4V on-state), current ratings (250A peak pulse at 8/20µs, 80A at 10/1000µs), and TO-226-2 packaging. No circuit modifications are required.

Q: What is the difference between the P2300EB and P2300EBL?

A: The primary differences are product status and RoHS compliance. The P2300EB is obsolete and RoHS non-compliant. The P2300EBL is active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Why is the P2300EB classified as obsolete?

A: The P2300EB has been discontinued by Littelfuse Inc. The P2300EBL serves as the active production equivalent and is the recommended part for new designs and replacements.

Q: Are there packaging differences between these parts?

A: No. Both the P2300EB and P2300EBL use TO-226-2 and TO-92-2 (TO-226AC) packaging with through-hole mounting. PCB layouts and assembly processes remain unchanged.

Q: What inventory considerations apply to these parts?

A: The P2300EB has limited remaining inventory (2,400 units). The P2300EBL is actively stocked with significantly higher availability (20,400 units). For new procurement, the P2300EBL is the recommended choice.
