P1602AARP Equivalent & Substitute Parts

Part Overview

The P1602AARP is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for overvoltage protection applications requiring 65V/130V off-state voltage ratings with 150A peak pulse current capability. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The P1602AARP operates as a 2-element TVS thyristor in a 3-SIP TO-220 Modified package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1602AARP is determined by strict equivalence across the following critical parameters:

• Voltage ratings (Breakover: 95V/190V; Off-State: 65V/130V; On-State: 4V)
• Current specifications (Peak Pulse 8/20µs: 150A; Peak Pulse 10/1000µs: 45A; Hold Current: 150mA)
• Element configuration (2 elements)
• Capacitance values (35pF, 60pF)
• Physical package (3-SIP, TO-220 Modified, Through Hole mounting)
• Series designation (SIDACtor®)

The P1602AALRP meets all these criteria and qualifies as a direct substitute. Packaging format differences (bulk vs. Tape & Reel) do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

The P1602AALRP is the direct electrical and mechanical equivalent of the P1602AARP. Selection between these parts should be based on the following factors:

Product Status: The P1602AARP is obsolete, while the P1602AALRP maintains active product status with Littelfuse Inc. For new designs and long-term production continuity, the P1602AALRP is the appropriate choice.

Regulatory Compliance: The P1602AALRP is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The P1602AARP is RoHS non-compliant and may not satisfy procurement specifications for applications subject to these regulations.

Packaging: Both parts are electrically identical. The P1602AALRP is supplied in Tape & Reel format, suitable for automated assembly processes, while the P1602AARP is supplied in bulk packaging. Packaging selection depends on production volume and assembly methodology.

Availability: The P1602AALRP has confirmed inventory availability (669 pcs) and active manufacturing status, ensuring supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the P1602AALRP be used as a direct replacement for the P1602AARP in existing designs?

A: Yes. The P1602AALRP is electrically and mechanically identical to the P1602AARP across all specified parameters, including voltage ratings, current ratings, element configuration, capacitance, and physical package dimensions. No circuit modifications are required.

Q: What is the difference between the P1602AARP and P1602AALRP?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (bulk vs. Tape & Reel). All electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with the TO-220 Modified package?

A: No. Both parts use the identical 3-SIP TO-220 Modified package with through-hole mounting. PCB footprints, lead spacing, and thermal characteristics are equivalent.

Q: Does the Tape & Reel packaging of the P1602AALRP affect its electrical performance?

A: No. Packaging format does not affect electrical performance, voltage ratings, current ratings, or any other functional specification. Tape & Reel packaging is a supply format optimization for automated assembly.

Q: Is the P1602AALRP suitable for applications requiring RoHS compliance?

A: Yes. The P1602AALRP is ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for RoHS-restricted applications.
