P1500EC Equivalent & Substitute Parts

Part Overview

The P1500EC is a 140V off-state TVS thyristor manufactured by Littelfuse Inc., part of the SIDACtor® series. This component is designed for transient voltage suppression applications requiring 400A peak pulse current capability in a TO-226-2 package. The P1500EC is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1500EC is determined by electrical parameter equivalence across all voltage and current ratings. The P1500ECL qualifies as a direct substitute based on matching specifications:

• Identical off-state voltage: 140V
• Identical breakover voltage: 180V
• Identical on-state voltage: 4V
• Identical peak pulse current (8/20µs): 400A
• Identical peak pulse current (10/1000µs): 100A
• Identical hold current: 150mA
• Identical capacitance: 95pF
• Identical package and mounting configuration: TO-226-2, TO-92-2 (TO-226AC), through-hole

The primary distinction between these parts is product status and compliance certification, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The P1500ECL is the direct equivalent for the obsolete P1500EC. Selection of P1500ECL is appropriate for:

• New designs requiring 140V off-state TVS thyristor functionality
• Replacement of P1500EC in existing applications where component refresh is necessary
• Applications requiring ROHS3 compliance certification
• Designs where active product status and ongoing manufacturer support are required

The P1500ECL maintains identical electrical and mechanical specifications while offering improved compliance status and active product availability.

Frequently Asked Questions (FAQ)

Q: Can P1500ECL be used as a direct replacement for P1500EC?

A: Yes. The P1500ECL is electrically and mechanically identical to the P1500EC across all specified parameters, including voltage ratings, current ratings, capacitance, and package configuration.

Q: What is the primary difference between P1500EC and P1500ECL?

A: The P1500EC is obsolete with RoHS non-compliant status, while P1500ECL is an active product with ROHS3 compliance certification. Electrical and mechanical performance are identical.

Q: Are there any package or mounting differences?

A: No. Both parts use identical TO-226-2, TO-92-2 (TO-226AC) packages with through-hole mounting. Direct PCB substitution is possible without layout modification.

Q: What compliance certifications apply to P1500ECL?

A: P1500ECL carries ROHS3 compliance and REACH unaffected status. The P1500EC does not meet these certifications.

Q: Is inventory availability a consideration for selection?

A: P1500ECL has significantly higher inventory availability (20,100 pcs) compared to P1500EC (683 pcs), supporting long-term procurement reliability.
