P3002AB Equivalent & Substitute Parts

Part Overview

The P3002AB is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for overvoltage protection applications, featuring dual-element configuration with 140V/280V off-state voltage ratings and 250A peak pulse current capability in a 3-SIP TO-220 Modified package. The P3002AB is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3002AB is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitute relationships:

• Voltage ratings must match exactly: Breakover voltage (180V, 360V), Off-State voltage (140V, 280V), and On-State voltage (4V)
• Peak pulse current specifications must be identical: 250A at 8/20µs and 80A at 10/1000µs
• Hold current (Ih) must equal 150 mA
• Number of elements must remain 2
• Capacitance values must match: 55pF and 95pF
• Package configuration must be 3-SIP with Through Hole mounting
• Supplier Device Package must be TO-220 Modified

The P3002ABL meets all these criteria and qualifies as a direct substitute for the obsolete P3002AB.

Parameter Comparison

Engineering Selection Recommendations

The P3002ABL is the direct substitute for the obsolete P3002AB. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications. The primary distinction between these parts is product status and regulatory compliance.

The P3002AB is classified as obsolete and carries RoHS non-compliant status. The P3002ABL is an active product with ROHS3 compliance and REACH Unaffected designation, making it suitable for applications subject to current environmental and regulatory requirements. Both components maintain identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Selection of the P3002ABL over the P3002AB is appropriate for new designs, system upgrades, and long-term component availability assurance.

Frequently Asked Questions (FAQ)

Q: Can the P3002ABL be used as a direct replacement for the P3002AB in existing designs?
