P4202ACRP Equivalent & Substitute Parts

Part Overview

The P4202ACRP is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. as part of the SIDACtor® series. This component is designed for overvoltage protection applications, featuring dual-element configuration with 190V/380V off-state voltage ratings and 400A peak pulse current capability in a 3-SIP TO-220 Modified package. The P4202ACRP is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4202ACRP is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, P4202ACLRP, maintains identical electrical specifications including breakover voltage (250V, 500V), off-state voltage (190V, 380V), on-state voltage (4V), peak pulse current ratings (400A at 8/20µs and 100A at 10/1000µs), hold current (150mA), element count (2), and capacitance values (50pF, 85pF). Both parts share the same mechanical configuration: 3-SIP package type and TO-220 Modified supplier device package with through-hole mounting.

The key differentiator between the main part and its substitute is product status and packaging format. The P4202ACRP is obsolete and supplied in standard packaging, while P4202ACLRP is an active product available in Tape & Reel (TR) format, ensuring continued supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The P4202ACLRP is the direct functional equivalent for the obsolete P4202ACRP. Selection of P4202ACLRP is justified on the following grounds:

Electrical equivalence is complete across all specified parameters, ensuring identical circuit performance in overvoltage protection applications.

Product status: P4202ACLRP is active and in production, providing assured long-term supply availability compared to the obsolete P4202ACRP.

Regulatory compliance: P4202ACLRP meets ROHS3 compliance requirements, whereas P4202ACRP is non-compliant. For applications subject to RoHS directives, P4202ACLRP is the required selection.

Packaging format: P4202ACLRP is supplied in Tape & Reel (TR) format, supporting automated assembly processes. The standard packaging of P4202ACRP is no longer available.

Frequently Asked Questions (FAQ)

Q: Can P4202ACLRP directly replace P4202ACRP in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: breakover voltage, off-state voltage, on-state voltage, peak pulse current ratings, hold current, element count, capacitance, package type, and mounting configuration. Direct substitution is valid.

Q: What is the difference between P4202ACRP and P4202ACLRP?

A: The parts are electrically equivalent. The primary differences are: P4202ACRP is obsolete with standard packaging; P4202ACLRP is active with Tape & Reel packaging. P4202ACLRP also meets ROHS3 compliance, while P4202ACRP does not.

Q: Is the Tape & Reel (TR) packaging of P4202ACLRP compatible with through-hole assembly?

A: Yes. Tape & Reel is a supply format for automated handling and placement. The component itself remains a through-hole mounted 3-SIP package in TO-220 Modified configuration, compatible with standard PCB assembly processes.

Q: Are there any performance differences between the two parts?

A: No. All electrical specifications are identical: 250V/500V breakover voltage, 190V/380V off-state voltage, 4V on-state voltage, 400A peak pulse current (8/20µs), 100A peak pulse current (10/1000µs), 150mA hold current, dual elements, and 50pF/85pF capacitance.

Q: Why should I use P4202ACLRP instead of P4202ACRP?

A: P4202ACRP is obsolete and no longer manufactured. P4202ACLRP is the active equivalent with assured supply, ROHS3 compliance, and modern packaging for automated assembly.
