Key Parameters

Substitute Part Grouping Explanation

The V100ZA4P qualifies as a parametric equivalent to the V100ZC4P based on the following substitution criteria:

• Identical varistor voltage range: 90 V (Min), 100 V (Typ), 110 V (Max)
• Matching surge current rating: 2.5 kA
• Equivalent maximum voltage ratings: 60 V AC, 81 V DC
• Identical energy dissipation: 10 J
• Same mounting configuration: Through Hole, Disc 10mm package
• Matching capacitance specification: 1200 pF @ 1 MHz
• Identical operating temperature range: -55°C to 85°C
• Equivalent regulatory compliance: ROHS3 Compliant, REACH Unaffected

Both components belong to the Littelfuse varistor product line with active product status, differing only in internal series designation (ZC versus ZA).

Parameter Comparison

Engineering Selection Recommendations

Both V100ZC4P and V100ZA4P are active product status components with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain considerations rather than performance differentiation. The V100ZA4P currently maintains higher inventory levels (2100 pcs versus 635 pcs), making it suitable for high-volume procurement scenarios. Both components satisfy ROHS3 compliance requirements and REACH regulatory frameworks, ensuring compatibility with modern manufacturing and end-use environments.

Frequently Asked Questions (FAQ)

Q: Can V100ZA4P directly replace V100ZC4P in existing designs? A: Yes. Both components share identical electrical ratings, surge current capacity, voltage thresholds, and thermal operating ranges. The through-hole disc 10mm package configuration is mechanically interchangeable.

Q: What determines substitution eligibility for these varistors? A: Substitution is valid when varistor voltage (typical value), surge current rating, maximum voltage ratings (AC and DC), energy dissipation, package type, and operating temperature range are identical. Series designation (ZC versus ZA) does not affect functional equivalence.

Q: Are there compliance differences between these parts? A: No. Both components carry identical RoHS3 compliance, REACH unaffected status, MSL rating of 1 (Unlimited), and EAR99 export classification.

Q: What is the significance of the 10mm disc package specification? A: The 10mm disc package defines the physical footprint and mounting hole configuration for through-hole PCB assembly. Both substitute parts maintain this specification, ensuring mechanical fit and electrical connection compatibility.

Q: How do capacitance specifications affect substitution? A: Capacitance at 1 MHz (1200 pF for both parts) is a parasitic characteristic of the varistor structure. Identical capacitance values ensure equivalent high-frequency transient response and circuit behavior.
