V130LC20CP Equivalent & Substitute Parts

Part Overview

The V130LC20CP is a 205 V, 10 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the C-III series. This through-hole disc component (20mm) is designed for transient voltage protection applications requiring high surge current capacity and energy absorption. The part is currently active in production with 893 units in stock. Substitute parts are necessary when addressing supply chain constraints, regional availability, or specific application requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the V130LC20CP is determined by the following critical parameters:

Varistor Voltage (Typ): Substitute parts must operate within the specified range of 184.5 V to 225.5 V to ensure equivalent transient suppression performance.
Current - Surge: Substitute parts must support 10 kA surge current capacity to maintain protection integrity.
Number of Circuits: Single-circuit configuration required.
Mounting Type: Through-hole mounting required for PCB compatibility.
Operating Temperature Range: Substitute parts must support the application's thermal environment.
RoHS Compliance: ROHS3 compliance required for regulatory alignment.

The identified substitute parts, ERZ-V20D201 and ERZ-V20R201 (both Panasonic Electronic Components, ZNR® series), meet these core substitution criteria. Both parts operate at 200 V typical varistor voltage (within the acceptable range), support 10 kA surge current, feature single-circuit through-hole disc configuration, and maintain ROHS3 compliance. Physical package dimensions differ slightly (21.5mm vs. 20mm), requiring mechanical verification during integration.

Engineering Selection Recommendations

Both ERZ-V20D201 and ERZ-V20R201 are qualified substitutes for the V130LC20CP based on electrical parameter alignment and regulatory compliance. All three parts maintain ROHS3 compliance and active production status, ensuring long-term availability and supply chain stability.

The primary engineering consideration is the energy rating differential: the V130LC20CP provides 200 J energy absorption, while both Panasonic substitutes provide 140 J. Applications requiring the full 200 J energy capacity must account for this reduction in transient energy handling capability.

The operating temperature range for Panasonic substitutes (-40°C to 85°C) is narrower than the Littelfuse part (-55°C to 85°C). Applications operating below -40°C require the original V130LC20CP specification.

Physical package dimensions differ: the Panasonic parts measure 21.5mm disc diameter compared to the 20mm disc of the V130LC20CP. PCB layout and mechanical clearance must accommodate this dimensional variance.

Frequently Asked Questions (FAQ)

Q: Can ERZ-V20D201 and ERZ-V20R201 be used interchangeably with V130LC20CP?

A: Both Panasonic parts meet the core electrical substitution criteria (varistor voltage range, 10 kA surge current, single-circuit configuration, through-hole mounting, ROHS3 compliance). However, the reduced energy rating (140 J vs. 200 J) and narrower operating temperature range (-40°C to 85°C vs. -55°C to 85°C) must be evaluated against specific application requirements.

Q: What is the significance of the varistor voltage range?

A: The varistor voltage determines the threshold at which the component begins conducting to suppress transient overvoltages. The V130LC20CP operates at 205 V typical, with acceptable range 184.5 V to 225.5 V. Both Panasonic substitutes operate at 200 V typical (185 V to 225 V range), providing functionally equivalent transient suppression within this specification window.

Q: How do the energy ratings affect component selection?

A: Energy rating (measured in joules) indicates the maximum transient energy the varistor can safely absorb. The V130LC20CP absorbs 200 J, while ERZ-V20D201 and ERZ-V20R201 absorb 140 J. Applications experiencing high-energy transient events may require the higher energy capacity of the original part.

Q: Are there mechanical compatibility concerns?

A: Yes. The V130LC20CP features a 20mm disc package, while both Panasonic substitutes use 21.5mm disc packages. PCB footprints, lead spacing, and mechanical clearances must be verified to ensure physical fit within the application assembly.

Q: What is the difference between ERZ-V20D201 and ERZ-V20R201?

A: Both parts share identical electrical specifications and package dimensions. The designation difference (D vs. R) reflects Panasonic's internal product coding. Inventory levels differ (5581 units for ERZ-V20D201 vs. 1529 units for ERZ-V20R201), which may influence supply chain decisions.

Q: Are all three parts RoHS compliant?

A: Yes. The V130LC20CP, ERZ-V20D201, and ERZ-V20R201 are all ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
