P2202ACMC Equivalent & Substitute Parts

Part Overview

The P2202ACMC is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for overvoltage protection applications. This device features dual-element configuration with 90V/180V off-state voltage ratings and 400A peak pulse current capability in a 3-SIP TO-220 modified package. The P2202ACMC is classified as obsolete, making identification of functionally equivalent active alternatives essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2202ACMC is determined by electrical and mechanical parameter equivalence across the following criteria:

• Voltage ratings (off-state, breakover, and on-state) must match exactly
• Peak pulse current specifications (8/20µs and 10/1000µs) must be identical
• Hold current (Ih) must be equivalent
• Number of elements must remain constant at 2
• Capacitance values must align
• Package configuration (3-SIP) and mounting type (through hole) must be preserved
• Supplier device package (TO-220 Modified) must be maintained

The P2202ACMCL meets all substitution criteria as a direct equivalent with identical electrical specifications and mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

The P2202ACMCL is the direct functional equivalent for the obsolete P2202ACMC. Both devices share identical electrical and mechanical specifications, ensuring pin-for-pin and functionally equivalent replacement capability.

Selection between these parts is determined by regulatory and compliance requirements:

• For applications requiring RoHS3 compliance, the P2202ACMCL is the appropriate selection, as it meets ROHS3 standards while the P2202ACMC does not.
• For legacy systems or applications without RoHS compliance mandates, either part may be used based on availability and supply chain considerations.
• The P2202ACMCL carries active product status, ensuring ongoing manufacturer support and supply availability, whereas the P2202ACMC is obsolete and subject to inventory depletion.

Frequently Asked Questions (FAQ)

Q: Can the P2202ACMCL directly replace the P2202ACMC in existing designs?

A: Yes. The P2202ACMCL is electrically and mechanically identical to the P2202ACMC. All voltage ratings, current specifications, hold current, element count, capacitance values, and package configuration are equivalent. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The P2202ACMC is obsolete with RoHS non-compliant status, while the P2202ACMCL is active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between P2202ACMC and P2202ACMCL?

A: No. Both parts use the 3-SIP TO-220 modified package with through-hole mounting. PCB layout and mechanical integration remain unchanged.

Q: Which part should be selected for new designs?

A: The P2202ACMCL should be selected for new designs due to its active product status and RoHS3 compliance, ensuring long-term supply availability and regulatory alignment.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts deliver identical electrical performance across all specified parameters: 90V/180V off-state voltage, 130V/260V breakover voltage, 4V on-state voltage, 400A peak pulse current (8/20µs), 100A peak pulse current (10/1000µs), and 150mA hold current.
