P2353AC Equivalent & Substitute Parts

Part Overview

The P2353AC is a Transient Voltage Suppressors (TVS) thyristor manufactured by Littelfuse, designed for overvoltage protection applications. This component features a 200V off-state voltage rating with 400A peak pulse current capability in a 3-SIP through-hole package. The P2353AC is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2353AC is determined by matching the following critical electrical and mechanical parameters:

• Voltage ratings: Breakover voltage of 270V, off-state voltage of 200V, and on-state voltage of 8V
• Current specifications: Peak pulse current (8/20µs) of 400A and peak pulse current (10/1000µs) of 100A
• Hold current: 150mA minimum
• Element count: 3 elements
• Capacitance range: 50pF to 75pF
• Package configuration: 3-SIP through-hole mounting
• Supplier device package: TO-220 Modified

The P2353ACL meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The P2353ACL is the direct substitute for the obsolete P2353AC. Both components share identical electrical specifications and mechanical packaging. The primary distinction is product status and regulatory compliance: the P2353ACL is active in production and ROHS3 compliant, whereas the P2353AC is obsolete and RoHS non-compliant. For new designs and ongoing system support, the P2353ACL is the appropriate selection. Both components carry the same ECCN and HTSUS classifications, ensuring consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can P2353ACL replace P2353AC in existing applications? A: Yes. The P2353ACL is electrically and mechanically identical to the P2353AC. All voltage ratings, current specifications, element count, and package dimensions match exactly.

Q: What is the difference between P2353AC and P2353ACL? A: The primary differences are product status and compliance. The P2353AC is obsolete and RoHS non-compliant. The P2353ACL is active in production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts? A: No. Both components use the same 3-SIP through-hole package with TO-220 Modified supplier device packaging. Mounting and PCB layout requirements are identical.

Q: What does the "L" suffix in P2353ACL indicate? A: The "L" suffix denotes the active, compliant variant of the P2353AC series. It indicates ROHS3 compliance and current production status.

Q: Can I use P2353ACL in designs originally specified for P2353AC? A: Yes. The P2353ACL is a direct substitute with no design modifications required. Pin configuration, electrical performance, and thermal characteristics are identical.
