LVR200S PTC Resettable Fuse Equivalent & Substitute Parts

Part Overview

The LVR200S is a polymeric PTC resettable fuse manufactured by Littelfuse Inc., designed for 240V applications with a 2A hold current rating. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and component procurement. The LVR200S operates as a thermal protection device that automatically resets after a fault condition is cleared, providing reliable circuit protection in radial disc configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LVR200S is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, LVR200S-240, maintains identical electrical characteristics including voltage rating (240V/265V Int), hold current (2A), trip current (4A), and resistance specifications. Both components share the same polymeric PTC technology, radial disc package configuration, through-hole mounting type, and lead spacing (0.400"). The substitution is valid based on matching all critical protection parameters and mechanical form factor. The key differentiator between the main part and substitute is product status and packaging format: LVR200S is obsolete with tape packaging, while LVR200S-240 is active with bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

The LVR200S-240 is the direct equivalent substitute for the obsolete LVR200S. Both components are manufactured by Littelfuse within the PolySwitch® LVR series and maintain identical electrical protection characteristics and mechanical specifications. The LVR200S-240 holds active product status with current manufacturing support and bulk packaging availability, making it the appropriate choice for new designs and component replacement applications. Both parts carry equivalent regulatory approvals (CQC, CSA, TUV, UL) and maintain ROHS3 compliance, ensuring compatibility with current environmental and safety standards.

Frequently Asked Questions (FAQ)

Q: Can LVR200S-240 be used as a direct replacement for LVR200S? A: Yes. Both components are electrically and mechanically identical, with matching voltage ratings (240V/265V Int), hold current (2A), trip current (4A), resistance specifications, and radial disc package configuration. The primary difference is product status and packaging format.

Q: What is the significance of the product status difference between obsolete and active? A: The LVR200S is classified as obsolete, indicating discontinued manufacturing. The LVR200S-240 maintains active status with ongoing production and availability. For new applications and long-term procurement, the active LVR200S-240 is the recommended selection.

Q: Are the mechanical dimensions identical between these parts? A: Yes. Both components share identical dimensions: 0.980" L x 0.240" W (24.90mm x 6.10mm), height of 1.331" (33.80mm), and lead spacing of 0.400" (10.15mm). They are compatible with the same PCB layouts and mounting configurations.

Q: Do both parts meet the same regulatory requirements? A: Yes. Both LVR200S and LVR200S-240 carry identical approvals from CQC, CSA, TUV, and UL, and both are ROHS3 compliant.

Q: What is the difference in packaging between these parts? A: The LVR200S is supplied in tape packaging, while LVR200S-240 is supplied in bulk packaging. The packaging format does not affect electrical or mechanical performance.
