P1402AA Equivalent & Substitute Parts

Part Overview

The P1402AA is a SIDACtor® Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection in electronic circuits. This component features dual-element configuration with 58V/116V off-state voltage ratings and 150A peak pulse current capability in a 3-SIP TO-220 Modified package. The P1402AA 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 P1402AA is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, P1402AALRP, maintains identical electrical specifications including breakover voltage (77V, 154V), off-state voltage (58V, 116V), on-state voltage (4V), peak pulse current ratings (150A at 8/20µs, 45A at 10/1000µs), hold current (150mA), element count (2), and capacitance values (35pF, 60pF). Both parts utilize the same 3-SIP package configuration with through-hole mounting in TO-220 Modified supplier packaging.

The key differentiator between P1402AA and P1402AALRP is packaging format and product status. P1402AA is supplied in standard packaging and is obsolete. P1402AALRP is supplied in Tape & Reel (TR) format and maintains active product status with current RoHS3 compliance and REACH unaffected certification.

Tape & Reel packaging format of P1402AALRP is suitable for automated assembly processes.

For legacy systems currently using P1402AA, direct substitution with P1402AALRP is electrically and mechanically valid. No circuit modifications or design changes are required.

Frequently Asked Questions (FAQ)

Q: Can P1402AALRP directly replace P1402AA in existing circuits? A: Yes. P1402AALRP is electrically and mechanically equivalent to P1402AA. All voltage ratings, current specifications, element count, capacitance values, and package configuration are identical. Direct substitution requires no circuit modifications.

Q: What is the difference between P1402AA and P1402AALRP? A: The primary differences are product status and packaging format. P1402AA is obsolete and supplied in standard packaging. P1402AALRP is active and supplied in Tape & Reel (TR) format. Additionally, P1402AALRP meets ROHS3 compliance and REACH unaffected certification, while P1402AA is RoHS non-compliant.

Q: Are there any electrical performance differences between these parts? A: No. Both parts share identical electrical specifications: 77V/154V breakover voltage, 58V/116V off-state voltage, 4V on-state voltage, 150A peak pulse current (8/20µs), 45A peak pulse current (10/1000µs), 150mA hold current, dual-element configuration, and 35pF/60pF capacitance values.

Q: Is the 3-SIP TO-220 Modified package the same for both parts? A: Yes. Both P1402AA and P1402AALRP use identical 3-SIP package configuration with TO-220 Modified supplier packaging and through-hole mounting. PCB layout and thermal management considerations remain unchanged.

Q: Why should I use P1402AALRP instead of P1402AA? A: P1402AALRP is the active equivalent with current regulatory compliance. P1402AA is obsolete, creating supply chain risk. P1402AALRP ensures long-term availability, meets ROHS3 requirements, and is suitable for both legacy system support and new designs.

Q: Does packaging format affect circuit performance? A: No. Tape & Reel (TR) packaging of P1402AALRP is a supply and assembly format difference only. Electrical and mechanical performance are identical to standard packaging. TR format is optimized for automated assembly processes.
