P4802ABRP Equivalent & Substitute Parts

Part Overview

The P4802ABRP is a Littelfuse SIDACtor® Transient Voltage Suppressor (TVS) thyristor designed for overvoltage protection in 220V and 440V applications. This component features a 250A peak pulse current rating and is housed in a 3-SIP TO-220 Modified package. The P4802ABRP 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 for the P4802ABRP is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

• Identical voltage ratings: Breakover (300V, 600V) and Off-State (220V, 440V)
• Matching on-state voltage: 4 V
• Equivalent peak pulse current ratings: 250 A (8/20µs) and 80 A (10/1000µs)
• Identical hold current: 150 mA
• Same element count: 2 elements
• Matching capacitance range: 50pF, 85pF
• Compatible package: 3-SIP TO-220 Modified through-hole mounting

The P4802ABL and P4802ABLRP meet all electrical and mechanical requirements for direct substitution. Both parts are manufactured by Littelfuse Inc. within the SIDACtor® series and maintain identical performance specifications. The primary differences are packaging format (bulk versus tape & reel) and product status (both active versus obsolete).

Engineering Selection Recommendations

For new designs and ongoing procurement, P4802ABL or P4802ABLRP are the appropriate selections to replace the obsolete P4802ABRP. Both substitute parts maintain full electrical and mechanical compatibility while offering active product status and ROHS3 compliance.

Selection between P4802ABL and P4802ABLRP depends on procurement requirements: P4802ABL is supplied in bulk packaging, while P4802ABLRP is supplied in tape & reel format. Both parts are manufactured by Littelfuse Inc. and carry identical electrical specifications, ROHS3 compliance, and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can P4802ABL or P4802ABLRP be used as direct replacements for P4802ABRP?

A: Yes. Both parts are electrically and mechanically identical to the P4802ABRP across all specified parameters including voltage ratings, current ratings, capacitance, and package configuration.

Q: What is the difference between P4802ABL and P4802ABLRP?

A: The electrical and mechanical specifications are identical. The difference is packaging format: P4802ABL is supplied in bulk, while P4802ABLRP is supplied in tape & reel format. Selection depends on assembly process requirements and procurement volume.

Q: Why is the P4802ABRP listed as obsolete?

A: The P4802ABRP has been discontinued by Littelfuse Inc. The active equivalents P4802ABL and P4802ABLRP provide the same functionality with current product support and compliance certifications.

Q: Are there compliance differences between the obsolete and substitute parts?

A: Yes. The P4802ABRP is RoHS non-compliant, while both P4802ABL and P4802ABLRP are ROHS3 compliant and REACH unaffected. This makes the substitute parts suitable for applications requiring modern environmental compliance standards.

Q: Will the 3-SIP TO-220 Modified package fit existing PCB layouts designed for P4802ABRP?

A: Yes. All three parts use identical 3-SIP TO-220 Modified through-hole packaging, ensuring mechanical and electrical compatibility with existing board designs without layout modifications.
