P1500ECAP Equivalent & Substitute Parts

Part Overview

The P1500ECAP is a 140V off-state TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, designed for transient voltage suppression applications. This component features a TO-226-2 package with 400A peak pulse current capability and is currently classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is essential for ongoing system maintenance, redesigns, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P1500ECAP 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): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Capacitance: 95pF
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole
• Number of Elements: 1

The P1500ECLAP meets all these criteria and is classified as a direct substitute. The primary distinction between these parts is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The P1500ECLAP is the direct substitute for the P1500ECAP. Both components are manufactured by Littelfuse Inc. within the SIDACtor® series and share identical electrical specifications and package configurations.

The P1500ECLAP offers the following advantages:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance meets current environmental and regulatory requirements
• Tape & Box packaging is standard for production environments
• Identical electrical performance across all specified parameters

The P1500ECAP, being obsolete, should be replaced with the P1500ECLAP for new designs and ongoing procurement. Existing inventory of the P1500ECAP may be used in applications where RoHS compliance is not a requirement, provided supply remains available.

Frequently Asked Questions (FAQ)

Q: Can the P1500ECLAP be used as a direct replacement for the P1500ECAP?

A: Yes. The P1500ECLAP is electrically and mechanically identical to the P1500ECAP. All voltage ratings, current specifications, capacitance, and package configurations match exactly.

Q: What is the difference between the P1500ECAP and P1500ECLAP?

A: The primary differences are product status, packaging format, and RoHS compliance. The P1500ECAP is obsolete and RoHS non-compliant, while the P1500ECLAP is active, ROHS3 compliant, and supplied in Tape & Box packaging.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. Both parts use the TO-226-2 and TO-92-2 (TO-226AC) package with formed leads and through-hole mounting. PCB layouts and assembly processes require no modification.

Q: Does the P1500ECLAP meet current regulatory requirements?

A: Yes. The P1500ECLAP is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What inventory status should I expect for these parts?

A: The P1500ECAP has 838 pieces in stock but is obsolete. The P1500ECLAP has 933 pieces in stock and is actively manufactured, making it the recommended choice for new procurement.
