P1500EAAP Equivalent & Substitute Parts

Part Overview

The P1500EAAP 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 or TO-92-2 packages. The part is currently classified as obsolete, making identification of suitable substitutes necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1500EAAP is determined by matching the following critical electrical and mechanical parameters:

• 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
• Number of Elements: 1
• Mounting Type: Through Hole
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)

The P1500EALAP meets all these criteria and is therefore a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P1500EALAP is the direct substitute for the obsolete P1500EAAP. Both components are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and compliance posture: the P1500EALAP is currently in active production and carries ROHS3 compliance certification, whereas the P1500EAAP is obsolete and RoHS non-compliant. For new designs and ongoing system support, the P1500EALAP is the appropriate selection. Both components carry identical ECCN and HTSUS classifications and share unlimited moisture sensitivity level ratings.

Frequently Asked Questions (FAQ)

Q: Can P1500EALAP be used as a direct replacement for P1500EAAP in existing designs?

A: Yes. The P1500EALAP is electrically and mechanically identical to the P1500EAAP across all specified parameters, including voltage ratings, current ratings, capacitance, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between P1500EAAP and P1500EALAP?

A: The components are electrically equivalent. The primary differences are product status (P1500EAAP is obsolete; P1500EALAP is active) and RoHS compliance (P1500EAAP is non-compliant; P1500EALAP is ROHS3 compliant). Packaging differs in that P1500EALAP is supplied in Tape & Box format.

Q: Are there any compatibility concerns with the TO-226-2 and TO-92-2 package options?

A: Both the P1500EAAP and P1500EALAP support identical package options: TO-226-2 and TO-92-2 (TO-226AC) with formed leads. Package selection depends on application requirements and PCB layout; electrical performance is equivalent across both options.

Q: Does the ROHS3 compliance of P1500EALAP affect circuit performance compared to the non-compliant P1500EAAP?

A: No. RoHS compliance status reflects manufacturing and material standards, not electrical or functional performance. Both components deliver identical electrical characteristics and performance in circuit operation.

Q: What is the base product number relationship between these parts?

A: Both P1500EAAP and P1500EALAP share the base product number P1500, indicating they are variants within the same product family with identical core specifications.
