P2702AC Equivalent & Substitute Parts

Part Overview

The P2702AC is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. under the SIDACtor® series. This component provides bidirectional overvoltage protection with 120V/240V off-state voltage ratings and 400A peak pulse current capability in a 3-SIP through-hole package. The P2702AC is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2702AC is based on electrical and mechanical parameter equivalence. The substitute parts P2702ACL and P2702ACLRP maintain identical electrical specifications across all critical parameters: breakover voltage (160V, 320V), off-state voltage (120V, 240V), on-state voltage (4V), peak pulse current ratings (400A at 8/20µs and 100A at 10/1000µs), hold current (150mA), element count (2), capacitance values (60pF, 105pF), and mechanical form factor (3-SIP, TO-220 Modified through-hole package).

The key differentiators between substitute parts are packaging format and product status. P2702ACL is supplied in bulk packaging, while P2702ACLRP is supplied in tape and reel format. Both substitute parts maintain active product status and comply with ROHS3 and REACH requirements, addressing the obsolescence of the original P2702AC.

Parameter Comparison

Engineering Selection Recommendations

Both P2702ACL and P2702ACLRP are direct functional equivalents to the obsolete P2702AC, with identical electrical and mechanical specifications. Selection between these two substitute parts depends on procurement and assembly requirements.

P2702ACL in bulk packaging is suitable for applications requiring manual component handling or lower-volume production runs. P2702ACLRP in tape and reel format is appropriate for automated assembly processes and higher-volume manufacturing environments.

Both substitute parts offer improved compliance status compared to the original P2702AC. P2702ACL and P2702ACLRP are ROHS3 compliant and REACH unaffected, whereas the P2702AC is RoHS non-compliant. This compliance improvement makes either substitute part the appropriate choice for new designs and production transitions away from the obsolete P2702AC.

Frequently Asked Questions (FAQ)

Q: Can P2702ACL or P2702ACLRP be used as direct replacements for P2702AC?

A: Yes. Both substitute parts maintain identical electrical parameters (voltage ratings, current ratings, capacitance) and mechanical form factor (3-SIP, TO-220 Modified through-hole package). They are direct functional equivalents.

Q: What is the difference between P2702ACL and P2702ACLRP?

A: The primary difference is packaging format. P2702ACL is supplied in bulk packaging for manual handling, while P2702ACLRP is supplied in tape and reel format for automated assembly. Electrical and mechanical specifications are identical.

Q: Why is the P2702AC listed as obsolete?

A: The P2702AC has been discontinued by the manufacturer. P2702ACL and P2702ACLRP are the active product line replacements with equivalent performance and improved compliance characteristics.

Q: Are there any compliance differences between the substitute parts and the original P2702AC?

A: Yes. P2702ACL and P2702ACLRP are ROHS3 compliant and REACH unaffected, while P2702AC is RoHS non-compliant. This makes the substitute parts suitable for applications with regulatory compliance requirements.

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

A: P2702ACL and P2702ACLRP have identical through-hole pinouts and mechanical dimensions. They are mechanically interchangeable. Selection depends on whether manual or automated assembly is used.
