LVR005NS-1 Equivalent & Substitute Parts

Part Overview

The LVR005NS-1 is a Polymeric PTC Resettable Fuse manufactured by Littelfuse, part of the PolySwitch® LVR series. This component provides overcurrent protection at 240V (265V internal rating) with a 50 mA hold current and 120 mA trip current. The device is designed for through-hole radial mounting in disc configuration and is currently in active production status. Substitute parts are identified when identical electrical and mechanical parameters are maintained across different packaging or inventory sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LVR005NS-1 is determined by strict equivalence across the following critical parameters:

• Voltage rating: 240V (265V internal)
• Current hold specification: 50 mA maximum
• Current trip specification: 120 mA
• Resistance characteristics: Initial minimum 18.5 Ohms, post-trip maximum 65 Ohms
• Mounting configuration: Through hole radial disc
• Physical dimensions: 0.272" diameter × 0.181" thickness (6.90mm × 4.60mm)
• Lead spacing: 0.200" (5.08mm)
• Operating temperature range: -20°C to 85°C
• Polymeric PTC type classification
• PolySwitch® LVR series designation

The LVR005NS variant meets all electrical and mechanical parameters required for direct substitution. Packaging differences (tape and reel versus bag) do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both LVR005NS-1 and LVR005NS are active production components from Littelfuse with identical electrical specifications and mechanical form factors. Selection between these parts is determined by packaging requirements and inventory availability rather than functional performance.

The LVR005NS-1 is supplied in tape and reel packaging, suitable for automated assembly processes. The LVR005NS is supplied in bag packaging, appropriate for manual assembly or lower-volume applications.

Both components carry equivalent regulatory approvals (CQC, CSA, TUV, UL) and maintain ROHS3 compliance. No functional differences exist between these variants for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Can LVR005NS be used as a direct replacement for LVR005NS-1?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (tape and reel versus bag). Functional performance in the circuit is equivalent.

Q: What determines if a part can substitute for the LVR005NS-1?

A: Substitution requires matching all electrical parameters (voltage, current hold, current trip, resistance values, time to trip) and mechanical specifications (dimensions, lead spacing, mounting type). The PolySwitch® LVR series designation and polymeric PTC type must be maintained.

Q: Does packaging format affect circuit performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical and mechanical characteristics remain identical regardless of whether the component is supplied in tape and reel or bag packaging.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both LVR005NS-1 and LVR005NS operate across the identical temperature range of -20°C to 85°C.

Q: What regulatory certifications apply to these parts?

A: Both components carry CQC, CSA, TUV, and UL approvals and are ROHS3 compliant.
