Key Parameters

Substitute Part Grouping Explanation

The P3203ACL60 qualifies as a direct substitute for the P3203AC60 based on electrical and mechanical parameter equivalence. Substitution is determined by matching the following critical parameters:

• Voltage ratings: Breakover (350V), off-state (270V), and on-state (8V)
• Current specifications: Peak pulse (8/20µs) at 400A and (10/1000µs) at 100A
• Hold current: 150mA
• Element count: 3 elements
• Capacitance range: 45pF and 70pF
• Physical package: 3-SIP with TO-220 Modified supplier device package
• Mounting configuration: Through-hole

The P3203ACL60 maintains identical electrical performance and physical form factor, enabling direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The P3203ACL60 is the appropriate substitute for the obsolete P3203AC60. Both components are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications across all critical parameters. The P3203ACL60 offers the additional advantage of active product status and ROHS3 compliance, making it suitable for new designs and systems requiring regulatory compliance. The transition from P3203AC60 to P3203ACL60 requires no circuit modifications or design changes.
