V180ZC5P Equivalent & Substitute Parts

Part Overview

The V180ZC5P is a 180V, 2.5kA disc varistor manufactured by Littelfuse Inc., designed for transient voltage suppression applications. This through-hole component operates across a temperature range of -55°C to 85°C and is ROHS3 compliant. The part is currently active in production with 850 units in stock. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain considerations necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The V180ZA5P qualifies as a parametric equivalent to the V180ZC5P based on the following criteria:

Electrical Parameters Match:

• Varistor voltage range: 162V (Min) to 198V (Max), with 180V typical
• Surge current capacity: 2.5 kA
• Maximum AC/DC voltage ratings: 115V AC / 153V DC
• Energy dissipation: 18 J
• Capacitance: 465 pF @ 1 MHz

Mechanical Parameters Match:

• Mounting type: Through Hole
• Package form factor: Disc 10mm
• Number of circuits: 1

Compliance & Environmental Match:

• RoHS3 compliant
• Operating temperature range: -55°C to 85°C
• Moisture sensitivity level: 1 (Unlimited)
• REACH status: Unaffected

Both parts belong to the Littelfuse varistor product line and share identical functional specifications, differing only in internal series designation (ZC vs. ZA).

Parameter Comparison

Engineering Selection Recommendations

Both the V180ZC5P and V180ZA5P are active production components from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain considerations rather than electrical or mechanical performance differences.

The V180ZC5P (ZC series) carries 850 units in current inventory. The V180ZA5P (ZA series) provides an alternative with 3735 units available, offering greater stock depth for high-volume procurement or extended lead time mitigation.

Both components satisfy identical circuit requirements for 180V transient voltage suppression applications with 2.5kA surge capacity. PCB layout, thermal management, and system integration considerations remain unchanged between selections.

Frequently Asked Questions (FAQ)

Q: Can V180ZA5P be used as a direct replacement for V180ZC5P in existing designs?

A: Yes. Both parts share identical electrical specifications (180V typical varistor voltage, 2.5kA surge current), mechanical form factor (10mm disc through-hole), and environmental ratings (-55°C to 85°C). No circuit redesign or PCB modification is required.

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

A: The series designation reflects internal manufacturing or product line categorization within Littelfuse. From an engineering standpoint, both series deliver identical performance parameters for this voltage and current rating.

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

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental qualifications are equivalent.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be influenced by supplier availability, inventory levels, or procurement lead times. The V180ZA5P currently offers higher stock availability (3735 units vs. 850 units).

Q: Are there any thermal or frequency-dependent performance differences?

A: No. Both parts operate across the same temperature range (-55°C to 85°C) and exhibit identical capacitance characteristics (465 pF @ 1 MHz).
