Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2702AARP is determined by electrical and mechanical parameter equivalence. The critical parameters governing substitution are:

• Voltage ratings (Breakover, Off-State, and On-State)
• Peak pulse current specifications (8/20µs and 10/1000µs)
• Hold current (Ih)
• Element count and capacitance values
• Physical package configuration (3-SIP, TO-220 Modified)
• Mounting type (Through Hole)

The P2702AALRP meets all electrical and mechanical requirements of the P2702AARP. Both components share identical voltage ratings, current ratings, element configuration, and package specifications. The primary distinction is packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The P2702AALRP is the direct substitute for the P2702AARP. Both components are manufactured by Littelfuse Inc. and provide identical electrical and mechanical performance within the SIDACtor® series.

The P2702AALRP offers the following advantages:

• Active product status ensures ongoing manufacturer support and availability
• ROHS3 compliance meets current environmental and regulatory requirements
• Tape & Reel packaging format supports automated assembly processes

The P2702AARP remains suitable for applications where existing inventory is available and regulatory compliance requirements do not mandate RoHS certification. However, for new designs and long-term production requirements, the P2702AALRP is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the P2702AARP and P2702AALRP electrically interchangeable?

A: Yes. Both components share identical voltage ratings (160V/320V breakover, 120V/240V off-state), current specifications (150A peak pulse at 8/20µs, 45A at 10/1000µs), and hold current (150mA). They are functionally equivalent in circuit applications.

Q: What is the difference between these two part numbers?

A: The primary differences are product lifecycle status, RoHS compliance, and packaging format. The P2702AARP is obsolete and RoHS non-compliant, supplied in bulk packaging. The P2702AALRP is active, ROHS3 compliant, and supplied in Tape & Reel format.

Q: Can I use P2702AALRP in place of P2702AARP in existing designs?

A: Yes. The P2702AALRP is a direct substitute. Both components use identical 3-SIP TO-220 Modified packages with through-hole mounting, ensuring mechanical and electrical compatibility in existing PCB layouts.

Q: Why should I transition from P2702AARP to P2702AALRP?

A: The P2702AARP is obsolete, which limits future availability and manufacturer support. The P2702AALRP is an active product with ROHS3 compliance, making it suitable for current manufacturing standards and regulatory requirements.

Q: Are there any performance differences between these parts?

A: No. Both components deliver identical electrical performance across all specified parameters: breakover voltage, off-state voltage, on-state voltage, peak pulse current, hold current, element count, and capacitance values.
