P1602AB Equivalent & Substitute Parts

Part Overview

The P1602AB is a TVS thyristor manufactured by Littelfuse Inc., designed for transient voltage suppression applications. It features a 65V/130V off-state voltage rating with 250A peak pulse current capability in a 3-SIP TO-220 Modified package. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1602AB is determined by electrical and mechanical parameter equivalence within the SIDACtor® TVS thyristor family. The critical parameters governing substitutability are:

• Voltage ratings (breakover and off-state): 95V/190V and 65V/130V respectively
• Peak pulse current capability: 250A at 8/20µs pulse width
• On-state voltage: 4V
• Hold current: 150mA
• Package configuration: 3-SIP in TO-220 Modified form factor
• Number of elements: 2

The P1602ABL meets all electrical and mechanical requirements identical to the P1602AB, with the primary distinction being packaging format (bulk versus tape/reel) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P1602ABL is a direct functional equivalent to the P1602AB with identical electrical and mechanical specifications. The P1602ABL is the preferred selection for new designs and ongoing procurement due to its active product status and ROHS3 compliance. The P1602AB, classified as obsolete, should be replaced with the P1602ABL in applications where component availability and regulatory compliance are considerations.

Frequently Asked Questions (FAQ)

Q: Can the P1602ABL be used as a direct replacement for the P1602AB?

A: Yes. The P1602ABL provides identical electrical performance and mechanical compatibility. Both parts share the same voltage ratings (95V/190V breakover, 65V/130V off-state), current ratings (250A peak pulse at 8/20µs), on-state voltage (4V), and 3-SIP TO-220 Modified package configuration.

Q: What is the difference between P1602AB and P1602ABL?

A: The primary differences are product status and compliance. The P1602AB is obsolete and RoHS non-compliant, while the P1602ABL is active and ROHS3 compliant. Packaging format differs (standard versus bulk), but electrical and mechanical specifications are identical.

Q: Are there any package or mounting considerations when substituting these parts?

A: No. Both parts use identical through-hole mounting in the 3-SIP TO-220 Modified package configuration, ensuring direct PCB compatibility without layout modifications.

Q: Why is the P1602AB classified as obsolete?

A: The P1602AB has been superseded by the P1602ABL within the Littelfuse product portfolio. The P1602ABL offers the same functionality with improved regulatory compliance and active manufacturing status.
