Key Parameters for Substitution:

• Varistor voltage range (Min: 61.2 V, Typ: 68 V, Max: 74.8 V)
• Surge current rating (500 A)
• Maximum DC and AC voltage ratings (56 V DC, 40 V AC)
• Energy dissipation capacity (6.5 J)
• Physical package (Disc 10mm, through-hole mounting)
• Operating temperature range (-55°C ~ 85°C)
• Capacitance characteristics (1850 pF @ 1 MHz)

Both parts belong to the Littelfuse ZC and ZA series respectively, maintaining identical electrical performance specifications and mechanical compatibility for direct circuit substitution.

Parameter Comparison

Engineering Selection Recommendations

Both V68ZC3P and V68ZA3P are active production components from Littelfuse Inc. with identical electrical specifications and mechanical form factors. Selection between these parts is based on availability and inventory status rather than technical performance differences. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications requiring environmental compliance. The through-hole disc package (10mm) is suitable for PCB mounting in standard circuit board designs with compatible pad spacing.
