P1500EARP2 Equivalent & Substitute Parts

Part Overview

The P1500EARP2 is a 140V off-state, 150A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring through-hole mounting in TO-226-2 and TO-92-2 packages. The P1500EARP2 is classified as obsolete product status. Finding equivalent substitute parts is necessary to maintain design continuity and ensure supply chain availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1500EARP2 is determined by electrical and mechanical parameter equivalence within the SIDACtor® series. The critical parameters for substitution are:

• Voltage - Off State: 140V
• Voltage - Breakover: 180V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 150A
• Current - Peak Pulse (10/1000µs): 45A
• Current - Hold (Ih): 150mA
• Capacitance: 40pF
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole

The P1500EALRP2 meets all electrical and mechanical specifications identical to the P1500EARP2. The primary distinction is packaging format: P1500EALRP2 is supplied in Tape & Reel (TR) configuration versus the P1500EARP2 standard packaging. Both components share the same base product number (P1500) and are manufactured by Littelfuse Inc.

Parameter Comparison

Engineering Selection Recommendations

The P1500EALRP2 is the direct substitute for the P1500EARP2. Both components are electrically and mechanically identical across all specified parameters. The P1500EALRP2 offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the P1500EALRP2 is ROHS3 compliant, whereas the P1500EARP2 is RoHS non-compliant. For new designs and production applications, the P1500EALRP2 is the appropriate selection. The Tape & Reel packaging of the P1500EALRP2 is suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are the P1500EARP2 and P1500EALRP2 electrically identical?

A: Yes. Both components share identical electrical specifications including voltage ratings (140V off-state, 180V breakover, 4V on-state), current ratings (150A peak pulse at 8/20µs, 45A at 10/1000µs, 150mA hold current), and capacitance (40pF).

Q: What is the difference between P1500EARP2 and P1500EALRP2?

A: The primary difference is packaging format. The P1500EALRP2 is supplied in Tape & Reel (TR) configuration, while the P1500EARP2 uses standard packaging. The P1500EALRP2 also has active product status and ROHS3 compliance, compared to the obsolete status and RoHS non-compliance of the P1500EARP2.

Q: Can I use P1500EALRP2 in place of P1500EARP2 in existing designs?

A: Yes. The P1500EALRP2 is a direct electrical and mechanical substitute. Both components use identical TO-226-2 and TO-92-2 packages with through-hole mounting, making them interchangeable at the circuit board level.

Q: Is the P1500EALRP2 suitable for automated assembly?

A: Yes. The Tape & Reel packaging of the P1500EALRP2 is designed for automated pick-and-place assembly processes.

Q: What is the RoHS compliance status difference?

A: The P1500EARP2 is RoHS non-compliant, while the P1500EALRP2 is ROHS3 compliant. For applications requiring RoHS compliance, the P1500EALRP2 is the appropriate selection.
