P4202ACMC Equivalent & Substitute Parts

Part Overview

The P4202ACMC is a SIDACtor® thyristor-based transient voltage suppressor manufactured by Littelfuse Inc., designed for overvoltage protection in 190V/380V off-state applications. This component features a 400A peak pulse current rating and is housed in a 3-SIP TO-220 Modified package. The P4202ACMC is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent protection characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4202ACMC is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings (Breakover: 250V/500V; Off-State: 190V/380V; On-State: 4V)
• Current specifications (Peak Pulse 8/20µs: 400A; Peak Pulse 10/1000µs: 100A; Hold Current: 150mA)
• Element configuration (2 elements)
• Capacitance range (30pF, 50pF)
• Physical package (3-SIP, TO-220 Modified, Through Hole mounting)

The P4202ACMCL qualifies as a direct substitute based on identical electrical performance and mechanical compatibility across all specified parameters. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The P4202ACMCL is the direct functional equivalent of the P4202ACMC. Selection between these parts is determined by regulatory and supply chain requirements:

• P4202ACMCL is the preferred selection for new designs and ongoing production. This part maintains active product status and achieves ROHS3 compliance, meeting current environmental and regulatory standards. Bulk packaging format supports production environments.

• P4202ACMC is obsolete and non-compliant with RoHS3 standards. This part number should not be selected for new applications. Existing inventory may be used only where regulatory exemptions apply or legacy system maintenance is required.

Both parts deliver identical electrical performance and mechanical compatibility, ensuring direct substitution without circuit redesign or performance degradation.
