Substitute Part Grouping Explanation

Substitution of the P4802AB60 is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitution:

• Voltage ratings: Breakover voltage (300V, 600V) and off-state voltage (220V, 440V) must match exactly
• Current specifications: Peak pulse current (8/20µs) of 250 A and (10/1000µs) of 80 A must be maintained
• Hold current: 150 mA minimum requirement
• Package configuration: 3-SIP through-hole mounting in TO-220 Modified package
• Element count: Dual-element (2) configuration
• Capacitance range: 50pF to 85pF

The P4802ABL60 meets all electrical and mechanical requirements for direct substitution, with the primary distinction being product status and compliance certifications.
