Key Parameters

Substitute Part Grouping Explanation

The V140LS2P qualifies as a parametric equivalent to the V140LU2P based on the following criteria:

All electrical parameters are identical: Maximum AC voltage (140V), maximum DC voltage (180V), varistor voltage range (198V–242V with 220V typical), surge current (1.2kA), energy rating (12J), circuit count (1), and capacitance (160pF @ 1MHz).

Operating temperature range matches exactly: -55°C to 85°C.

Mechanical compatibility is maintained: Both components use through-hole mounting with identical disc 7mm packaging.

Compliance and regulatory status are equivalent: Both are ROHS3 compliant, REACH unaffected, and share the same ECCN (EAR99) and HTSUS classification.

The only difference is packaging format: V140LU2P is supplied in Tape & Reel (TR), while V140LS2P is supplied in Cut Tape (CT). This distinction does not affect electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the V140LU2P and V140LS2P are active production components from Littelfuse with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and supply chain considerations.

The V140LU2P in Tape & Reel format is suitable for high-volume automated assembly processes. The V140LS2P in Cut Tape format accommodates lower-volume applications or manual assembly workflows.

Both components meet ROHS3 compliance and REACH requirements, making them suitable for applications subject to these regulatory standards. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can V140LS2P replace V140LU2P in my circuit design?

A: Yes. Both parts are electrically and mechanically identical. The V140LS2P provides the same 220V varistor voltage, 1.2kA surge current, and 12J energy rating. The only difference is packaging format (Cut Tape vs. Tape & Reel).

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging provides components on tape segments, suitable for manual handling or lower-volume assembly. Both formats contain identical components.

Q: Are there any compliance differences between these parts?

A: No. Both V140LU2P and V140LS2P carry identical certifications: ROHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and MSL rating of 1 (Unlimited).

Q: Which part should I specify for new designs?

A: Selection depends on your assembly process. For automated high-volume production, specify V140LU2P (Tape & Reel). For lower-volume or manual assembly, specify V140LS2P (Cut Tape). Both are active production parts with equivalent performance.

Q: Do these parts have identical operating temperature ranges?

A: Yes. Both the V140LU2P and V140LS2P operate across -55°C to 85°C, with identical maximum AC (140V) and DC (180V) voltage ratings.
