V180ZC20P Equivalent & Substitute Parts

Part Overview

The V180ZC20P is a 180 V, 6.5 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc package (20mm). This component is designed for transient overvoltage protection in electronic circuits operating at 115 V AC maximum or 153 V DC maximum. The part is currently active in production with 853 units in stock.

Substitute parts are identified when they maintain identical electrical performance characteristics and mechanical compatibility, allowing direct replacement without circuit redesign or performance degradation.

Key Parameters

Substitute Part Grouping Explanation

The V180ZA20P qualifies as a parametric equivalent to the V180ZC20P based on the following substitution criteria:

Electrical Parameters (Identical):

• Varistor voltage range: 162 V (Min) to 198 V (Max), with 180 V typical
• Surge current rating: 6.5 kA
• Energy absorption: 52 J
• Maximum AC voltage: 115 V
• Maximum DC voltage: 153 V
• Capacitance: 2400 pF @ 1 MHz
• Operating temperature: -55°C to 85°C

Mechanical Parameters (Identical):

• Mounting type: Through Hole
• Package: Disc 20mm
• Number of circuits: 1

Compliance & Status (Identical):

• RoHS3 Compliant
• REACH Unaffected
• Product Status: Active

The only difference between these parts is the series designation (ZC versus ZA), which reflects internal manufacturing variations within Littelfuse's product line that do not affect electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the V180ZC20P and V180ZA20P are active production components from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: the V180ZC20P has 853 units in stock, while the V180ZA20P has 1532 units available.

Both parts meet ROHS3 compliance and REACH requirements, making them suitable for applications requiring environmental regulatory adherence. The through-hole disc package (20mm) ensures compatibility with standard PCB mounting practices.

Frequently Asked Questions (FAQ)

Q: Can V180ZA20P replace V180ZC20P in existing designs? A: Yes. Both parts have identical electrical ratings (180 V typical, 6.5 kA surge current, 52 J energy), identical mechanical packaging (through-hole disc 20mm), and identical operating temperature ranges (-55°C to 85°C). Direct substitution is supported without circuit modification.

Q: What is the difference between the ZC and ZA series designations? A: The series designation reflects internal manufacturing variations within Littelfuse's product line. No functional or performance differences exist between ZC and ZA variants for this 180 V varistor specification.

Q: Are both parts RoHS and REACH compliant? A: Yes. Both V180ZC20P and V180ZA20P are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts? A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these varistors be used in AC and DC circuits? A: Yes. Both parts are rated for maximum 115 V AC and 153 V DC operation, supporting applications in both AC and DC protection circuits.
