Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P2703AARP are determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitution:

• Identical voltage ratings: Breakover (300V), Off-State (230V), and On-State (8V)
• Identical current specifications: Peak Pulse (8/20µs) at 150A, Peak Pulse (10/1000µs) at 45A, and Hold current (Ih) at 150mA
• Identical element count: 3 elements
• Identical capacitance values: 25pF and 35pF
• Identical package configuration: 3-SIP, TO-220 Modified, through-hole mounting
• Same manufacturer: Littelfuse Inc.
• Same series designation: SIDACtor®

The substitute parts P2703AAL and P2703AALRP meet all these criteria. The distinction between them is packaging format only: P2703AAL is supplied in bulk packaging, while P2703AALRP is supplied in tape and reel format.

Parameter Comparison

Engineering Selection Recommendations

Both P2703AAL and P2703AALRP are direct functional equivalents to the obsolete P2703AARP. Selection between these two substitute parts should be based on procurement and assembly requirements:

P2703AAL is supplied in bulk packaging and is suitable for applications where components are manually placed or where tape and reel format is not required. This part carries ROHS3 compliance certification.

P2703AALRP is supplied in tape and reel format and is optimized for automated assembly processes. This part also carries ROHS3 compliance certification and REACH unaffected status.

Both substitute parts are currently in active production status with confirmed inventory availability, ensuring reliable supply chain access. The transition from the obsolete P2703AARP to either substitute part presents no electrical or mechanical compatibility issues, as all functional parameters remain identical.

Frequently Asked Questions (FAQ)

Q: Can P2703AAL and P2703AALRP be used interchangeably with P2703AARP?

A: Yes. Both parts are electrically and mechanically identical to the P2703AARP. The only difference is packaging format: P2703AAL uses bulk packaging while P2703AALRP uses tape and reel format. Selection depends on assembly method and procurement workflow.

Q: What is the difference between bulk and tape & reel packaging?

A: Bulk packaging (P2703AAL) supplies components loose in a container, suitable for manual assembly or small-volume applications. Tape and reel packaging (P2703AALRP) supplies components on continuous tape wound on a reel, optimized for automated pick-and-place assembly equipment.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both P2703AAL and P2703AALRP are ROHS3 compliant. The original P2703AARP is listed as RoHS non-compliant. If RoHS compliance is a design requirement, either substitute part satisfies this requirement.

Q: Will switching to a substitute part require PCB or assembly modifications?

A: No. Both substitute parts use the identical 3-SIP TO-220 modified package with through-hole mounting configuration. No PCB layout changes or assembly procedure modifications are necessary.

Q: What inventory levels are available for the substitute parts?

A: P2703AAL has 1350 pieces in stock. P2703AALRP has 876 pieces in stock. Both are listed as active products with confirmed new original inventory.
