Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V68ZC2P are identified based on strict parametric equivalence across the following critical specifications:

• Varistor voltage rating: 68 V (minimum 61.2 V, typical 68 V, maximum 74.8 V)
• Surge current capacity: 250 A
• Energy absorption: 3 J
• Maximum AC/DC voltage ratings: 40 V AC / 56 V DC
• Physical form factor: Disc 7mm through-hole package
• Operating temperature range: -55°C to 85°C
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign or performance impact.

Parameter Comparison

Engineering Selection Recommendations

The V68ZA2P is a direct parametric equivalent to the V68ZC2P. Both parts are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications across all critical parameters. Both parts carry active product status, ROHS3 compliance, and REACH Unaffected certification, confirming ongoing manufacturing support and regulatory alignment.

Selection between V68ZC2P and V68ZA2P may be based on inventory availability and supply chain considerations. The V68ZA2P currently maintains higher inventory levels (2983 pcs) compared to the V68ZC2P (726 pcs), which may influence procurement decisions for high-volume applications or extended lead-time mitigation strategies.

Frequently Asked Questions (FAQ)

Q: Can V68ZA2P be used as a direct replacement for V68ZC2P?

A: Yes. The V68ZA2P meets all parametric requirements for direct substitution. Electrical performance, surge current capacity, energy absorption, voltage ratings, and physical form factor are identical. Both parts are ROHS3 compliant and carry active product status.

Q: What is the difference between the ZC and ZA series designations?

A: The series designation (ZC vs. ZA) indicates internal manufacturing or design revision within the Littelfuse varistor product line. From an engineering standpoint, both series maintain identical electrical and mechanical specifications for the 68 V, 250 A rating, making them functionally interchangeable.

Q: Are there any temperature or environmental considerations when substituting these parts?

A: Both parts operate across the identical temperature range (-55°C to 85°C) and carry the same moisture sensitivity level (MSL 1 - Unlimited). No environmental or thermal derating adjustments are required when substituting between these parts.

Q: What packaging formats are available for these varistors?

A: Both the V68ZC2P and V68ZA2P are supplied in bulk packaging as through-hole disc components with 7mm form factor. No alternative package options are specified for these part numbers.

Q: How do I verify compatibility in my circuit design?

A: Verify that your circuit design specifies a 68 V varistor with 250 A surge current capacity, 3 J energy rating, and through-hole disc 7mm mounting. If these parameters match your design requirements, either part number is compatible without circuit modification.
