Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2353ACMC is determined by electrical and mechanical parameter equivalence. The primary substitute, P2353ACMCL, maintains identical electrical specifications across all critical parameters: breakover voltage (270V), off-state voltage (200V), on-state voltage (8V), peak pulse currents (400A at 8/20µs and 100A at 10/1000µs), hold current (150mA), element count (3), and capacitance values (30pF, 45pF). Both parts utilize the same 3-SIP package in TO-220 modified configuration with through-hole mounting. The substitution is valid based on complete electrical and mechanical parameter alignment.

Parameter Comparison

Engineering Selection Recommendations

The P2353ACMCL is the direct active equivalent for the obsolete P2353ACMC. Selection of P2353ACMCL is appropriate for new designs and replacement applications due to its active product status and ROHS3 compliance. The P2353ACMCL maintains full electrical and mechanical compatibility with the P2353ACMC, ensuring functional equivalence in transient voltage suppression applications. The transition from non-compliant to ROHS3-compliant status reflects current regulatory requirements for component procurement.

Frequently Asked Questions (FAQ)

Q: Can P2353ACMCL directly replace P2353ACMC in existing designs? A: Yes. The P2353ACMCL provides identical electrical performance across all specified parameters and uses the same 3-SIP TO-220 modified package with through-hole mounting. No circuit modifications are required.

Q: What is the primary reason for substitution? A: The P2353ACMC is obsolete. The P2353ACMCL is the active equivalent part from Littelfuse Inc., ensuring continued availability and regulatory compliance.

Q: Are there differences in packaging between these parts? A: Both parts use identical 3-SIP package configuration in TO-220 modified form with through-hole mounting. Packaging is equivalent.

Q: Does the P2353ACMCL meet current regulatory standards? A: Yes. The P2353ACMCL is ROHS3 compliant, whereas the P2353ACMC is non-compliant. This reflects updated environmental and safety standards.

Q: Are the electrical specifications identical? A: Yes. Breakover voltage, off-state voltage, on-state voltage, peak pulse currents, hold current, element count, and capacitance values are identical between both parts.
