P3002ACRP Equivalent & Substitute Parts

Part Overview

The P3002ACRP is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse, designed for overvoltage protection applications requiring 140V/280V off-state voltage rating with 400A peak pulse current capability in a 3-SIP TO-220 modified package. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3002ACRP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings: Breakover voltage (180V, 360V), off-state voltage (140V, 280V), and on-state voltage (4V) must match exactly
• Current specifications: Peak pulse current at 8/20µs (400A) and 10/1000µs (100A), and hold current (150mA) must be identical
• Physical configuration: Number of elements (2), capacitance values (55pF, 95pF), package type (3-SIP), and through-hole mounting must be preserved
• Supplier device package designation: TO-220 Modified configuration must be maintained

The P3002ACLRP meets all these criteria as a direct functional equivalent with identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The P3002ACLRP is the direct active equivalent for the obsolete P3002ACRP. Both components share identical electrical specifications and mechanical configuration, ensuring pin-for-pin and functional compatibility in existing circuit designs.

The P3002ACLRP offers the additional advantage of ROHS3 compliance, whereas the P3002ACRP is RoHS non-compliant. For new designs or applications subject to RoHS regulatory requirements, the P3002ACLRP is the appropriate selection. The P3002ACLRP is supplied in Tape & Reel packaging format, suitable for automated assembly processes, compared to the bulk packaging of the obsolete variant.

Frequently Asked Questions (FAQ)

Q: Can the P3002ACLRP be used as a direct replacement for the P3002ACRP?

A: Yes. The P3002ACLRP is electrically and mechanically identical to the P3002ACRP across all specified parameters, including voltage ratings, current ratings, element count, capacitance values, and package configuration. Pin-for-pin substitution is valid.

Q: What is the difference between the P3002ACRP and P3002ACLRP?

A: The primary differences are product status and compliance certifications. The P3002ACRP is obsolete and RoHS non-compliant, while the P3002ACLRP is active and ROHS3 compliant. Packaging format differs: P3002ACRP is supplied in bulk, while P3002ACLRP is supplied in Tape & Reel format.

Q: Are there any circuit design modifications required when switching from P3002ACRP to P3002ACLRP?

A: No circuit modifications are required. Electrical performance and mechanical compatibility are identical, allowing direct substitution without design changes.

Q: Does the Tape & Reel packaging of the P3002ACLRP affect compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. Tape & Reel packaging is a supply format suitable for automated assembly; the component itself maintains identical specifications and pinout.

Q: Is the P3002ACLRP suitable for applications requiring RoHS compliance?

A: Yes. The P3002ACLRP is ROHS3 compliant and REACH unaffected, making it appropriate for applications subject to RoHS regulatory requirements.
