Substitute Part Grouping Explanation

The V140LS2P is identified as a parametric equivalent to the V140LS2PX2855. Both parts share identical electrical specifications: 140 V maximum AC rating, 180 V maximum DC rating, 220 V typical varistor voltage, 1.2 kA surge current, and 12 J energy rating. Both components feature the same through-hole disc 7mm package, identical operating temperature range (-55°C to 85°C), and equivalent compliance certifications (ROHS3, REACH Unaffected).

The substitution is valid based on the following key parameters:

• Maximum AC Volts: 140 V
• Maximum DC Volts: 180 V
• Varistor Voltage (Typical): 220 V
• Current - Surge: 1.2 kA
• Energy: 12 J
• Mounting Type: Through Hole
• Package / Case: Disc 7mm
• Operating Temperature Range: -55°C to 85°C

The primary difference between these parts is packaging format: V140LS2PX2855 is supplied in tape and reel (TR) format, while V140LS2P is supplied in cut tape (CT) format.

Parameter Comparison

Engineering Selection Recommendations

Both V140LS2PX2855 and V140LS2P are active production components with identical electrical performance and compliance certifications. Selection between these parts should be based on packaging requirements and supply chain considerations. The V140LS2PX2855 in tape and 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 parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can V140LS2P be used as a direct replacement for V140LS2PX2855?

A: Yes. Both parts are electrically and mechanically identical, with matching varistor voltage (220 V typical), surge current (1.2 kA), energy rating (12 J), and operating temperature range (-55°C to 85°C). The difference is packaging format only: tape and reel versus cut tape.

Q: What is the difference between tape and reel (TR) and cut tape (CT) packaging?

A: Tape and reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut tape packaging supplies components on individual tape segments, typically used for lower-volume manual assembly or component kitting. Both formats contain identical components.

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

A: No. Both V140LS2PX2855 and V140LS2P carry identical certifications: ROHS3 compliant, REACH unaffected, MSL 1 (unlimited), and EAR99 export classification.

Q: What determines substitution eligibility for this varistor?

A: Substitution is valid when the following parameters match: maximum AC voltage (140 V), maximum DC voltage (180 V), varistor voltage range (198–242 V), surge current (1.2 kA), energy rating (12 J), mounting type (through hole), package form (disc 7mm), and operating temperature range (-55°C to 85°C).

Q: Can these parts be used interchangeably in circuit designs?

A: Yes. The electrical and mechanical specifications are identical, allowing direct substitution in circuit designs. Assembly process compatibility should be verified based on available equipment and production workflow.
