Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V22ZC3P are identified based on the following critical parameters that determine functional equivalence:

• Varistor Voltage (Typical): 22 V nominal rating
• Varistor Voltage Tolerance: 19.8 V minimum to 24.2 V maximum
• Surge Current Rating: 1 kA
• Energy Absorption: 4 J
• Maximum AC/DC Operating Voltages: 14 V AC / 18 V DC
• Capacitance: 14730 pF @ 1 MHz
• Package Form Factor: Disc 14mm through-hole configuration
• Compliance Standards: ROHS3 compliant, REACH unaffected

The V22ZA3P from Littelfuse matches all electrical and mechanical specifications, differing only in the internal series designation (ZA versus ZC). This substitution maintains identical performance characteristics across all rated parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the V22ZC3P and V22ZA3P are active production components from Littelfuse with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain considerations. Both components maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The 14mm disc through-hole package ensures compatibility with standard PCB layouts designed for this form factor.

Frequently Asked Questions (FAQ)

Q: Can the V22ZA3P directly replace the V22ZC3P in existing designs?

A: Yes. The V22ZA3P provides direct functional equivalence across all electrical parameters, including varistor voltage rating, surge current capacity, energy absorption, and operating temperature range. The physical package dimensions and through-hole mounting configuration are identical.

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

A: The series designation reflects internal manufacturing or design revisions within Littelfuse's product line. Both series maintain identical electrical specifications and performance characteristics for the 22 V, 1 kA varistor rating.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the V22ZC3P and V22ZA3P carry identical ROHS3 compliance and REACH unaffected status. Both are rated for the same operating temperature range of -55°C to 85°C.

Q: What are the critical parameters for substitution in 22 V varistor applications?

A: Substitution requires matching the varistor voltage rating (22 V nominal with 19.8 V to 24.2 V tolerance), surge current capacity (1 kA), energy absorption (4 J), maximum AC/DC voltage limits (14 V AC / 18 V DC), and physical package form factor (Disc 14mm through-hole).

Q: Can these varistors be used in AC or DC circuits?

A: These components are rated for both AC and DC applications within specified voltage limits: maximum 14 V AC and maximum 18 V DC. Circuit design must ensure operating voltages remain within these limits.
