P1300ECRP1 Equivalent & Substitute Parts

Part Overview

The P1300ECRP1 is a 120V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling capability in a compact TO-226-2 package. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1300ECRP1 is determined by strict equivalence across the following critical parameters:

• Voltage - Breakover: 160V
• Voltage - Off State: 120V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Capacitance: 105pF
• Number of Elements: 1
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole

The P1300ECLRP1 meets all electrical and mechanical specifications identical to the main part. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P1300ECLRP1 is the direct functional equivalent of the P1300ECRP1 across all electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Product Status: The P1300ECRP1 is obsolete. The P1300ECLRP1 is active and currently manufactured, making it the appropriate choice for new designs and long-term system support.

Compliance: The P1300ECLRP1 is ROHS3 compliant, whereas the P1300ECRP1 is non-compliant. Systems subject to RoHS regulations must use the P1300ECLRP1.

Packaging: The P1300ECRP1 is supplied in bulk packaging. The P1300ECLRP1 is supplied in Tape & Reel format, which is standard for automated assembly processes. Packaging selection depends on production volume and assembly methodology.

Inventory Availability: Both parts are in stock. The P1300ECLRP1 has higher current inventory (1060 pcs versus 827 pcs).

Frequently Asked Questions (FAQ)

Q: Can the P1300ECLRP1 directly replace the P1300ECRP1 in existing designs?

A: Yes. All electrical parameters, mechanical dimensions, and pin configurations are identical. Direct substitution is possible without circuit modification.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (Active versus Obsolete), RoHS compliance (ROHS3 Compliant versus Non-compliant), and packaging format (Tape & Reel versus bulk). Electrical and mechanical specifications are identical.

Q: Does the packaging format affect electrical performance?

A: No. Tape & Reel and bulk packaging contain identical components. Packaging format affects only handling, storage, and assembly processes.

Q: Is the P1300ECLRP1 suitable for RoHS-regulated applications?

A: Yes. The P1300ECLRP1 is ROHS3 compliant. The P1300ECRP1 is not compliant and cannot be used in RoHS-regulated applications.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts are from the same SIDACtor® series with identical electrical characteristics, thermal ratings, and performance specifications.

Q: What is the recommended part for new designs?

A: The P1300ECLRP1 is recommended for new designs due to active product status, RoHS compliance, and current manufacturing support.
