P2702ACMC Equivalent & Substitute Parts

Part Overview

The P2702ACMC is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc., designed for overvoltage protection applications requiring 120V/240V off-state voltage ratings with 400A peak pulse current capability. The device is packaged in a 3-SIP TO-220 Modified configuration and operates as part of the SIDACtor® product series.

The P2702ACMC is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this protection topology is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2702ACMC is determined by the following critical parameters:

• Voltage ratings (Breakover and Off-State): Must match 160V/320V breakover and 120V/240V off-state specifications
• Peak pulse current capability (8/20µs): Must support 400 A minimum
• Peak pulse current capability (10/1000µs): Must support 100 A minimum
• Current hold (Ih): Must support 150 mA minimum
• Mounting type and package: Must be Through Hole, 3-SIP, TO-220 Modified configuration
• Number of elements: Must be compatible with circuit topology requirements

The P2702ACMCL meets these substitution criteria and is classified as a direct equivalent for the obsolete P2702ACMC.

Parameter Comparison

Engineering Selection Recommendations

The P2702ACMCL is the active production equivalent for the obsolete P2702ACMC. Both devices maintain identical voltage and current specifications across all critical protection parameters. The P2702ACMCL is preferred for new designs and production applications due to its active product status and ROHS3 compliance certification.

The P2702ACMCL exhibits a lower on-state voltage (4V versus 8V) and operates with two elements instead of three. These differences do not affect substitution eligibility when the circuit topology accommodates the reduced element count. Verification of circuit compatibility with the two-element configuration is required during design integration.

Frequently Asked Questions (FAQ)

Q: Can the P2702ACMCL directly replace the P2702ACMC in existing designs?

A: The P2702ACMCL maintains identical voltage ratings (160V/320V breakover, 120V/240V off-state) and current specifications (400A peak pulse at 8/20µs, 100A at 10/1000µs, 150mA hold current). Direct substitution is possible when the circuit design accommodates a two-element configuration instead of three elements. Circuit topology review is required.

Q: What is the significance of the voltage-on-state difference between these parts?

A: The P2702ACMCL operates at 4V on-state compared to 8V for the P2702ACMC. This lower voltage reduces power dissipation during transient suppression events. The difference does not affect the substitution decision when the application circuit is designed to operate within these parameters.

Q: Are there packaging or mounting differences between these parts?

A: Both devices use identical Through Hole mounting, 3-SIP package configuration, and TO-220 Modified supplier device package. No mechanical or board-level design changes are required for substitution.

Q: What compliance certifications differ between these parts?

A: The P2702ACMC is RoHS non-compliant. The P2702ACMCL is ROHS3 compliant and REACH unaffected. For applications requiring environmental compliance certification, the P2702ACMCL is the appropriate selection.

Q: Why does the P2702ACMCL have fewer elements than the P2702ACMC?

A: The element count difference reflects design optimization in the active product line. Both configurations deliver the specified voltage and current protection performance. Circuit topology compatibility must be confirmed during integration.
