P2702ACRP Equivalent & Substitute Parts

Part Overview

The P2702ACRP is a dual-element SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for 120V/240V off-state applications 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 P2702ACRP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings: Breakover voltage (160V, 320V) and off-state voltage (120V, 240V) must match exactly
• Current specifications: Peak pulse current (8/20µs and 10/1000µs) and hold current must be identical
• Package configuration: 3-SIP TO-220 Modified through-hole mounting
• Element count: Dual-element (2) thyristor configuration
• Capacitance values: 60pF and 105pF specifications

The P2702ACLRP meets all these criteria as a direct functional equivalent, with the primary distinction being packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P2702ACLRP is the direct equivalent for the obsolete P2702ACRP. Selection between these parts is determined by procurement and compliance requirements:

• For new designs or systems requiring RoHS3 compliance, the P2702ACLRP is the appropriate choice, as it maintains full electrical and mechanical equivalence while meeting current environmental standards.
• The P2702ACLRP is available in Tape & Reel packaging, suitable for automated assembly processes.
• Both parts share identical electrical performance across all specified parameters, ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can P2702ACLRP be used as a direct replacement for P2702ACRP?

A: Yes. The P2702ACLRP is electrically and mechanically equivalent to the P2702ACRP across all specified parameters, including voltage ratings, current specifications, element count, and package configuration.

Q: What is the difference between P2702ACRP and P2702ACLRP?

A: The primary differences are product status (Obsolete versus Active), packaging format (bulk versus Tape & Reel), and RoHS compliance (non-compliant versus ROHS3 Compliant). Electrical and mechanical specifications are identical.

Q: Is the P2702ACLRP suitable for through-hole PCB assembly?

A: Yes. Both parts use identical 3-SIP TO-220 Modified through-hole mounting, ensuring compatibility with existing PCB layouts and assembly processes.

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

A: Substitution is determined by exact equivalence in breakover voltage (160V, 320V), off-state voltage (120V, 240V), peak pulse current (400A at 8/20µs), hold current (150mA), dual-element configuration, and 3-SIP TO-220 Modified package.
