Electrical Parameters (Must Match):

• Varistor Voltage (Typical): 22 V
• Varistor Voltage Range: 19.8 V (Min) to 24.2 V (Max)
• Current - Surge: 100 A
• Maximum AC Volts: 14 V
• Maximum DC Volts: 18 V
• Energy: 0.2 J
• Capacitance @ Frequency: 1220 pF @ 1 MHz
• Number of Circuits: 1

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: Disc 5mm

Environmental & Compliance Parameters (Must Match):

• Operating Temperature: -55°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The V22ZA05P differs only in its internal series designation (ZA vs. ZC), while maintaining complete electrical and mechanical compatibility with the V22ZC05P.

Parameter Comparison

Engineering Selection Recommendations

Both the V22ZC05P and V22ZA05P are active production components from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: V22ZC05P has 927 units in stock, while V22ZA05P has 2205 units available. Both components meet ROHS3 compliance and REACH unaffected status, making them suitable for applications requiring environmental regulatory adherence. The series designation difference (ZC vs. ZA) does not affect functional performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can V22ZA05P be used as a direct replacement for V22ZC05P?

A: Yes. Both parts are manufactured by Littelfuse Inc. and share identical electrical parameters (22V typical varistor voltage, 100A surge current), mechanical specifications (through-hole disc 5mm package), and environmental ratings (-55°C to 85°C operating temperature). The series designation difference does not impact functional equivalence.

Q: What are the critical parameters that define substitution eligibility for this varistor?

A: Substitution eligibility is determined by: varistor voltage range (19.8V to 24.2V), surge current rating (100A), maximum AC/DC voltage ratings (14V/18V), energy rating (0.2J), package type (disc 5mm through-hole), and operating temperature range (-55°C to 85°C).

Q: Are there any compliance differences between V22ZC05P and V22ZA05P?

A: No. Both parts carry identical compliance certifications: ROHS3 compliant, REACH unaffected, MSL 1 (unlimited), and the same ECCN and HTSUS classifications.

Q: What is the significance of the series designation (ZC vs. ZA)?

A: The series designation indicates internal manufacturing variants within Littelfuse's varistor product line. Both ZC and ZA series maintain the same electrical and mechanical specifications for this 22V 100A rating, ensuring functional interchangeability.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both V22ZC05P and V22ZA05P use identical through-hole disc 5mm packaging, allowing direct substitution in existing PCB layouts without modification to footprints or mounting requirements.
