Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2604UATP is determined by electrical and mechanical parameter equivalence. The critical parameters defining substitutability are:

• Voltage ratings (Breakover: 300V/600V; Off-State: 220V/440V; On-State: 4V)
• Current specifications (Peak Pulse 8/20µs: 150A; Peak Pulse 10/1000µs: 45A; Hold Current: 150mA)
• Element count (4 elements)
• Capacitance range (20pF, 35pF)
• Package configuration (6-SMD, Gull Wing; Modified MS-013)
• Mounting type (Surface Mount)

The P2604UALTP meets all electrical and mechanical requirements for direct substitution with the P2604UATP.
