Key Parameters

Substitute Part Grouping Explanation

The V100ZA3P qualifies as a parametric equivalent to the V100ZC3P based on the following substitution criteria:

• Identical varistor voltage rating: 100 V (typical), with matching minimum (90 V) and maximum (110 V) tolerances
• Identical surge current capacity: 1.2 kA
• Identical maximum DC and AC voltage specifications: 81 V DC, 60 V AC
• Identical energy rating: 5 J
• Identical capacitance: 600 pF @ 1 MHz
• Identical operating temperature range: -55°C to 85°C
• Identical mounting configuration: Through Hole, Disc 7mm package
• Identical circuit count: 1 circuit
• Identical compliance certifications: ROHS3 Compliant, REACH Unaffected

The substitution is based on complete electrical and mechanical parameter alignment. Both parts belong to the Littelfuse varistor product line and share identical performance specifications across all critical suppression and thermal parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the V100ZC3P and V100ZA3P are active production components from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical differentiation. The V100ZA3P offers higher current inventory (4097 pcs vs. 1156 pcs), making it suitable for high-volume procurement scenarios. Both parts are suitable for direct substitution in 100 V transient voltage suppression applications requiring 1.2 kA surge capacity and 5 J energy handling in through-hole disc configurations.

Frequently Asked Questions (FAQ)

Q: Can V100ZA3P replace V100ZC3P in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Direct substitution is possible without circuit redesign or PCB layout modification.

Q: Are there differences in the series designation between ZC and ZA?

A: The series designation (ZC vs. ZA) reflects internal Littelfuse product line organization but does not affect electrical performance or mechanical compatibility. All critical parameters are identical.

Q: What determines substitution eligibility for these varistors?

A: Substitution is determined by matching varistor voltage rating (90–110 V range), surge current capacity (1.2 kA), maximum voltage ratings (81 V DC, 60 V AC), energy rating (5 J), capacitance (600 pF @ 1 MHz), operating temperature range (-55°C to 85°C), and physical package (Disc 7mm through-hole).

Q: Are both parts suitable for high-volume production?

A: Yes. Both V100ZC3P and V100ZA3P are active production components with full compliance certifications. The V100ZA3P has higher available inventory, making it preferable for large-scale manufacturing runs.

Q: Do these parts require different PCB footprints?

A: No. Both parts use identical through-hole Disc 7mm packaging, requiring no PCB layout changes for substitution.
