P1602ACRP Equivalent & Substitute Parts

Part Overview

The P1602ACRP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. as part of the SIDACtor® series. This component is a 65V/130V off-state, 400A peak pulse current device in a 3-SIP TO-220 Modified package designed for transient voltage suppression applications. The P1602ACRP is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1602ACRP is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitution:

• Voltage ratings (breakover and off-state) must match exactly: 95V/190V breakover and 65V/130V off-state
• Peak pulse current capability must match: 400 A at 8/20µs pulse width
• Hold current must match: 150 mA minimum
• Package and mounting configuration must be identical: 3-SIP, TO-220 Modified, through-hole mounting
• Number of elements must remain constant: 2 elements
• Capacitance values must match: 85pF and 145pF

The P1602ACLRP meets all these criteria and qualifies as a direct substitute for the obsolete P1602ACRP.

Parameter Comparison

Engineering Selection Recommendations

The P1602ACLRP is the direct substitute for the obsolete P1602ACRP. All electrical parameters and mechanical specifications are identical. The primary advantages of selecting the P1602ACLRP are:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance meets current environmental and regulatory requirements
• Tape & Reel packaging option supports automated assembly processes
• Identical electrical performance maintains circuit functionality without redesign

For applications requiring the P1602ACRP, transition to the P1602ACLRP without modification to PCB layout, schematic, or bill of materials part number references beyond the part number itself.

Frequently Asked Questions (FAQ)

Q: Can the P1602ACLRP be used as a direct replacement for the P1602ACRP?

A: Yes. The P1602ACLRP is electrically and mechanically identical to the P1602ACRP. All voltage ratings, current specifications, and package dimensions match exactly. The substitute requires no circuit modifications.

Q: What is the difference between the P1602ACRP and P1602ACLRP?

A: The primary differences are product status and compliance. The P1602ACRP is obsolete and RoHS non-compliant. The P1602ACLRP is active, ROHS3 compliant, and available in Tape & Reel packaging. Electrical and mechanical specifications are identical.

Q: Does the packaging format affect compatibility?

A: No. The P1602ACRP is supplied in bulk packaging, while the P1602ACLRP is available in Tape & Reel format. Both use the same 3-SIP TO-220 Modified package. The packaging format affects only handling and assembly processes, not electrical or mechanical compatibility.

Q: Is the P1602ACLRP suitable for new designs?

A: Yes. The P1602ACLRP is an active product with ROHS3 compliance, making it appropriate for new designs and long-term production requirements.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching voltage ratings (95V/190V breakover, 65V/130V off-state), peak pulse current (400 A at 8/20µs), hold current (150 mA), package type (3-SIP TO-220 Modified), and capacitance values (85pF, 145pF).
