P2703ACMC Equivalent & Substitute Parts

Part Overview

The P2703ACMC is a 230V off-state, 400A peak pulse thyristor transient voltage suppressor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for overvoltage protection applications requiring high current handling capability in a 3-SIP through-hole package configuration.

The P2703ACMC is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and new design requirements where this component specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2703ACMC is determined by matching the following critical electrical and mechanical parameters:

• Voltage ratings: Breakover voltage of 300V, off-state voltage of 230V, and on-state voltage of 8V
• Current specifications: Peak pulse current of 400A (8/20µs) and 100A (10/1000µs), with hold current of 150mA
• Element configuration: 3-element thyristor array
• Capacitance characteristics: 30pF and 40pF values
• Physical form factor: 3-SIP through-hole package in TO-220 Modified configuration

The P2703ACMCL meets all these criteria and qualifies as a direct substitute for the P2703ACMC.

Parameter Comparison

Engineering Selection Recommendations

The P2703ACMCL is the direct substitute for the P2703ACMC. Both components share identical electrical specifications and physical packaging. The P2703ACMCL is currently in active production status, whereas the P2703ACMC is obsolete.

The P2703ACMCL carries ROHS3 compliance certification, meeting current environmental regulatory requirements. The P2703ACMC is RoHS non-compliant. For new designs or applications subject to RoHS requirements, the P2703ACMCL is the appropriate selection.

Both parts are manufactured by Littelfuse Inc. within the SIDACtor® series and maintain full electrical and mechanical compatibility for direct substitution in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the P2703ACMCL directly replace the P2703ACMC in existing applications?

A: Yes. The P2703ACMCL is electrically and mechanically identical to the P2703ACMC. All voltage ratings, current specifications, element configuration, and package form factor are matched. Direct substitution is possible without circuit modification.

Q: What is the difference between the P2703ACMC and P2703ACMCL?

A: The primary differences are product status and regulatory compliance. The P2703ACMC is obsolete and RoHS non-compliant. The P2703ACMCL is in active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: No. Both the P2703ACMC and P2703ACMCL use the same 3-SIP through-hole package in TO-220 Modified configuration. PCB layout and mounting procedures remain unchanged.

Q: Why should I use the P2703ACMCL instead of the P2703ACMC?

A: The P2703ACMCL is the active production part with current availability. It meets ROHS3 environmental compliance standards required in many markets and applications. The P2703ACMC is obsolete and subject to supply discontinuation.

Q: Are the electrical characteristics guaranteed to be identical?

A: Yes. Both parts maintain identical breakover voltage (300V), off-state voltage (230V), on-state voltage (8V), peak pulse currents (400A at 8/20µs, 100A at 10/1000µs), hold current (150mA), and capacitance values (30pF, 40pF).
