P2702ABRP Equivalent & Substitute Parts

Part Overview

The P2702ABRP is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for 120V/240V off-state applications with 250A peak pulse current capability in a 3-SIP TO-220 Modified package. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The P2702ABRP maintains electrical and mechanical compatibility with active production alternatives that share identical electrical specifications and package configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2702ABRP 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 package with through-hole mounting
• Number of elements: 2-element configuration
• Capacitance values: 60pF and 105pF specifications

The substitute parts P2702ABL and P2702ABLRP meet all these criteria. The primary differences are product status (active vs. obsolete) and packaging format (bulk vs. tape & reel), which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, P2702ABL or P2702ABLRP are the appropriate selections due to active product status and ROHS3 compliance. Both substitute parts maintain full electrical and mechanical equivalence to the P2702ABRP.

Selection between P2702ABL and P2702ABLRP depends on packaging requirements: P2702ABL is supplied in bulk packaging, while P2702ABLRP is supplied in tape & reel format. Both are REACH unaffected and carry identical electrical specifications. The choice between these two is determined by assembly process requirements and inventory management practices rather than technical performance.

Frequently Asked Questions (FAQ)

Q: Can P2702ABL or P2702ABLRP be used as direct replacements for P2702ABRP in existing designs?

A: Yes. Both substitute parts are electrically and mechanically equivalent. All voltage ratings, current specifications, capacitance values, and package configurations are identical. The parts are pin-compatible and functionally interchangeable.

Q: What is the difference between P2702ABL and P2702ABLRP?

A: The electrical and mechanical specifications are identical. The difference is packaging format: P2702ABL is supplied in bulk packaging, while P2702ABLRP is supplied in tape & reel format. Selection depends on assembly process requirements.

Q: Why is P2702ABRP listed as obsolete?

A: P2702ABRP is an obsolete product status designation. Active equivalents (P2702ABL and P2702ABLRP) are available from Littelfuse Inc. with identical specifications and improved compliance certifications.

Q: Are there compliance differences between the parts?

A: P2702ABRP is RoHS non-compliant. Both substitute parts (P2702ABL and P2702ABLRP) are ROHS3 compliant and REACH unaffected, providing improved regulatory compliance for new applications.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, for through-hole assembly. Both substitute parts use the same 3-SIP TO-220 Modified package and mounting type. Assembly procedures and PCB footprints remain unchanged.
