P0080EARP1 Equivalent & Substitute Parts

Part Overview

The P0080EARP1 is a 6V off-state Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient overvoltage protection applications requiring 150 A peak pulse current capability in a TO-226-2 package configuration. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0080EARP1 is determined by electrical and mechanical parameter equivalence within the TVS thyristor category. The critical parameters governing substitution are:

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

The P0080EALRP1 maintains identical electrical specifications across all voltage and current parameters, capacitance, element count, and package configuration. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P0080EALRP1 is the direct functional equivalent of the P0080EARP1. Both components share identical electrical specifications and package configurations. The P0080EALRP1 is the preferred selection for new designs and replacement applications due to its active product status and ROHS3 compliance. The P0080EARP1, classified as obsolete, should be replaced with the P0080EALRP1 in all applications where component procurement is required.

The transition from P0080EARP1 to P0080EALRP1 involves no circuit redesign or board layout modifications, as electrical performance and physical package dimensions remain unchanged. The primary difference is packaging format (Tape & Reel for P0080EALRP1 versus bulk for P0080EARP1) and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can the P0080EALRP1 directly replace the P0080EARP1 in existing designs?

A: Yes. The P0080EALRP1 is electrically and mechanically identical to the P0080EARP1. No circuit modifications or board layout changes are required. Both components operate at identical voltage and current specifications within the same TO-226-2 package.

Q: What is the difference between P0080EARP1 and P0080EALRP1?

A: The components are electrically equivalent. The primary differences are product status (P0080EARP1 is obsolete; P0080EALRP1 is active) and packaging format (P0080EALRP1 is supplied in Tape & Reel). The P0080EALRP1 also carries ROHS3 compliance certification.

Q: Are there any package or pinout differences between these parts?

A: No. Both components use the TO-226-2, TO-92-2 (TO-226AC) package configuration with identical pinout and physical dimensions. Through-hole mounting specifications are unchanged.

Q: Why is the P0080EARP1 classified as obsolete?

A: The P0080EARP1 has been superseded by the P0080EALRP1. Littelfuse Inc. continues to support the SIDACtor® series with the active P0080EALRP1 variant, which includes updated regulatory compliance.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching voltage ratings (25V breakover, 6V off-state, 4V on-state), peak pulse current (150 A at 8/20µs, 45 A at 10/1000µs), hold current (50 mA), capacitance (150pF), and package configuration (TO-226-2). The P0080EALRP1 meets all these criteria.
