P1500ECRP2 Equivalent & Substitute Parts

Part Overview

The P1500ECRP2 is a 140V 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 through-hole mounting in TO-226-2 packaging. The P1500ECRP2 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1500ECRP2 is determined by matching the following electrical and mechanical parameters:

• Voltage - Off State: 140V
• Voltage - Breakover: 180V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Capacitance: 95pF
• Number of Elements: 1
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole

The P1500ECLRP2 meets all electrical specifications and mechanical requirements. The primary difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P1500ECLRP2 is the direct functional equivalent of the P1500ECRP2. Both components share identical electrical specifications and mechanical packaging. The P1500ECLRP2 is the preferred selection because it maintains Active product status, ensuring long-term availability and manufacturing support. Additionally, the P1500ECLRP2 is ROHS3 compliant, whereas the P1500ECRP2 is RoHS non-compliant. The packaging difference (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility and is determined by procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can P1500ECLRP2 be used as a direct replacement for P1500ECRP2?

A: Yes. Both parts are electrically and mechanically identical. All voltage ratings, current specifications, capacitance, and package dimensions match exactly.

Q: What is the difference between P1500ECRP2 and P1500ECLRP2?

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

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel packaging is a supply format used for automated assembly processes. Once the component is removed from the tape and reel and installed on the circuit board, electrical and mechanical performance is identical to bulk-packaged units.

Q: Is the P1500ECLRP2 suitable for new designs?

A: Yes. The P1500ECLRP2 is Active status with ROHS3 compliance, making it suitable for new designs and long-term production.

Q: Are there any pin or footprint differences between these parts?

A: No. Both parts use TO-226-2 (TO-92-2) packaging with formed leads. Pin configuration and footprint are identical.
