P1402AARP Equivalent & Substitute Parts

Part Overview

The P1402AARP is a SIDACtor® thyristor-based transient voltage suppressor (TVS) manufactured by Littelfuse Inc., designed for overvoltage protection in 58V/116V applications. This device features a 3-SIP package with TO-220 Modified form factor and is rated for 150 A peak pulse current (8/20µs). The P1402AARP 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 P1402AARP 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 (4 V), peak pulse current ratings (150 A at 8/20µs and 45 A at 10/1000µs), hold current (150 mA), element count (2), and capacitance values (35pF, 60pF). Both devices use the same 3-SIP package in TO-220 Modified form factor with through-hole mounting.

The key differentiator is product status and packaging format: P1402AALRP is active and supplied in Tape & Reel format, whereas P1402AARP is obsolete with standard packaging. Compliance certifications differ, with P1402AALRP meeting ROHS3 and REACH Unaffected standards.

Parameter Comparison

Engineering Selection Recommendations

P1402AALRP is the direct functional equivalent to P1402AARP and is the appropriate selection for applications requiring active product status and current manufacturing support. The substitute maintains all electrical performance characteristics and mechanical compatibility while offering improved compliance posture through ROHS3 certification and REACH Unaffected status. Tape & Reel packaging of P1402AALRP supports automated assembly processes where applicable.

For legacy systems currently using P1402AARP, P1402AALRP provides drop-in compatibility without circuit redesign or performance degradation. The identical electrical specifications, package form factor, and mounting configuration ensure functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can P1402AALRP replace P1402AARP in existing designs? A: Yes. P1402AALRP is electrically and mechanically equivalent to P1402AARP. All voltage ratings, current ratings, capacitance values, and package specifications are identical. The devices are functionally interchangeable.

Q: What is the primary difference between these parts? A: P1402AARP is obsolete, while P1402AALRP is active. P1402AALRP also includes ROHS3 compliance and REACH Unaffected certification. Packaging differs: P1402AALRP is supplied in Tape & Reel format versus standard packaging for P1402AARP.

Q: Are the voltage and current ratings identical? A: Yes. Both parts share identical breakover voltage (77V, 154V), off-state voltage (58V, 116V), on-state voltage (4 V), peak pulse current (150 A at 8/20µs), and hold current (150 mA) specifications.

Q: Does the TO-220 Modified package remain the same? A: Yes. Both P1402AARP and P1402AALRP use the 3-SIP package in TO-220 Modified form factor with through-hole mounting. PCB layout and thermal management considerations remain unchanged.

Q: Is Tape & Reel packaging compatible with manual assembly? A: Tape & Reel packaging is optimized for automated pick-and-place assembly. Manual assembly is possible but requires manual component extraction from the tape carrier.
