P4802ACMC Equivalent & Substitute Parts

Part Overview

The P4802ACMC is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. under the SIDACtor® series. This component is designed for overvoltage protection applications requiring 220V/440V off-state voltage ratings with 400A peak pulse current capability in a 3-SIP through-hole package. The P4802ACMC is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution of the P4802ACMC is determined by electrical and mechanical parameter equivalence across the following criteria:

• Voltage ratings (breakover and off-state) must match exactly: 300V/600V breakover and 220V/440V off-state
• Peak pulse current capability must be maintained at 400A (8/20µs) and 100A (10/1000µs)
• On-state voltage must remain at 4V
• Hold current (Ih) must be 150 mA
• Number of elements must be 2
• Capacitance range must be 30pF to 45pF
• Package configuration must be 3-SIP with TO-220 Modified supplier device package
• Mounting type must be through-hole

The P4802ACMCL meets all these criteria and serves as the direct active equivalent to the obsolete P4802ACMC.

Parameter Comparison

Engineering Selection Recommendations

The P4802ACMCL is the direct equivalent replacement for the obsolete P4802ACMC. All electrical parameters and mechanical specifications are identical. The primary distinction is product status: P4802ACMCL is actively manufactured and supported by Littelfuse Inc., whereas P4802ACMC is obsolete.

The P4802ACMCL additionally provides ROHS3 compliance, meeting current environmental and regulatory requirements for new designs and production. The P4802ACMC is RoHS non-compliant, which may restrict its use in applications subject to RoHS regulations.

For applications currently using P4802ACMC, transition to P4802ACMCL is recommended to ensure long-term component availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can P4802ACMCL be used as a direct replacement for P4802ACMC?

A: Yes. The P4802ACMCL is electrically and mechanically identical to the P4802ACMC. All voltage ratings, current ratings, and package specifications match exactly. The primary difference is that P4802ACMCL is an active product with current manufacturing support.

Q: What is the difference between P4802ACMC and P4802ACMCL?

A: The components are functionally equivalent. P4802ACMCL is the active production version of the obsolete P4802ACMC. P4802ACMCL also carries ROHS3 compliance certification, whereas P4802ACMC is RoHS non-compliant.

Q: Are there any package or mounting differences?

A: No. Both parts use the same 3-SIP package configuration with TO-220 Modified supplier device package and through-hole mounting. Physical dimensions and pin configurations are identical.

Q: Why is P4802ACMC listed as obsolete?

A: Littelfuse Inc. has transitioned production to the P4802ACMCL variant, which includes improved compliance certifications and ongoing manufacturing support. The P4802ACMC is no longer actively produced.

Q: Can I use P4802ACMCL in existing designs that specify P4802ACMC?

A: Yes. The electrical and mechanical specifications are identical, making P4802ACMCL a direct substitute. Designs may be updated to reference P4802ACMCL for improved component availability and regulatory compliance.
