P2703ACRP Equivalent & Substitute Parts

Part Overview

The P2703ACRP is a 230V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. as part of the SIDACtor® series. This component is designed for transient voltage suppression applications requiring three-element configuration in a TO-220 Modified package. The P2703ACRP is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution for the P2703ACRP is determined by electrical and mechanical parameter equivalence. The substitute parts P2703ACL and P2703ACLRP maintain identical electrical specifications across all critical parameters: breakover voltage, off-state voltage, on-state voltage, peak pulse currents, hold current, element count, and capacitance values. Both substitute parts share the same 3-SIP package configuration and through-hole mounting type, ensuring mechanical compatibility.

The primary distinction between substitute parts is packaging format: P2703ACL is supplied in bulk packaging, while P2703ACLRP is supplied in tape and reel format. Both substitute parts carry active product status, whereas the original P2703ACRP is obsolete.

Parameter Comparison

Engineering Selection Recommendations

Both P2703ACL and P2703ACLRP are direct electrical and mechanical equivalents to the obsolete P2703ACRP. Selection between the two substitute parts should be based on procurement and assembly requirements:

P2703ACL is appropriate for applications requiring bulk component quantities with manual placement or low-volume assembly processes.

P2703ACLRP is appropriate for automated assembly operations utilizing tape and reel feeding systems.

Both substitute parts carry ROHS3 compliance certification, providing regulatory advantage over the original non-compliant P2703ACRP. Inventory availability for both parts supports immediate procurement without design modification.

Frequently Asked Questions (FAQ)

Q: Can P2703ACL and P2703ACLRP be used interchangeably with P2703ACRP?

A: Yes. Both parts are electrically and mechanically identical to the P2703ACRP across all specified parameters. The difference is packaging format only: bulk versus tape and reel.

Q: What is the difference between P2703ACL and P2703ACLRP?

A: Both parts are identical in electrical performance and physical package. P2703ACL is supplied in bulk packaging for manual handling and placement. P2703ACLRP is supplied in tape and reel format for automated pick-and-place assembly equipment.

Q: Why is the P2703ACRP listed as obsolete?

A: The P2703ACRP has been superseded by active production variants. The substitute parts P2703ACL and P2703ACLRP represent the current active product line for this electrical specification.

Q: Are there compliance differences between the main part and substitutes?

A: Yes. The P2703ACRP is RoHS non-compliant. Both substitute parts P2703ACL and P2703ACLRP are ROHS3 compliant, meeting current regulatory requirements for electronic components.

Q: Will switching to a substitute part require PCB redesign?

A: No. Both substitute parts use the identical 3-SIP package and through-hole mounting configuration. Direct board-level substitution is possible without layout modification.

Q: What are the key electrical parameters that define substitution eligibility?

A: Breakover voltage (300V), off-state voltage (230V), on-state voltage (8V), peak pulse current ratings (400A at 8/20µs, 100A at 10/1000µs), hold current (150mA), element count (3), and capacitance values (50pF, 75pF) must remain constant for functional equivalence.
