Key Parameters

Substitute Part Grouping Explanation

The V275LS2P is classified as a parametric equivalent to the V275LS2PX2855. Substitution is valid based on the following criteria:

• Identical varistor voltage specifications (405 V minimum, 450 V typical, 495 V maximum)
• Matching surge current rating (1.2 kA)
• Equivalent energy absorption capacity (23 J)
• Same operating temperature range (-55°C to 85°C)
• Identical physical form factor (Disc 7mm through-hole)
• Matching electrical characteristics (80 pF capacitance @ 1 MHz)
• Equivalent compliance certifications (ROHS3, REACH Unaffected)

The primary difference between these parts is packaging format: V275LS2PX2855 is supplied in tape and reel (TR) configuration, while V275LS2P is supplied in cut tape (CT) configuration. Both are manufactured by Littelfuse Inc. within the LS series.

Parameter Comparison

Engineering Selection Recommendations

Both V275LS2PX2855 and V275LS2P are active production components from Littelfuse Inc. with identical electrical performance and compliance certifications. Selection between these parts should be based on packaging requirements and supply chain considerations:

• V275LS2PX2855 (Tape & Reel): Suitable for high-volume automated assembly processes requiring reel-based component feeding.
• V275LS2P (Cut Tape): Suitable for lower-volume applications, manual assembly, or when cut tape packaging is preferred for inventory management.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications. The electrical specifications, thermal performance, and mechanical form factor are identical, permitting direct substitution based on packaging availability and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can V275LS2P be used as a direct replacement for V275LS2PX2855?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (cut tape versus tape and reel). Direct substitution is valid for circuit design and electrical performance.

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 in shorter tape segments, typically used for manual assembly or lower-volume production runs. The components themselves are identical.

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

A: No. Both V275LS2PX2855 and V275LS2P carry identical ROHS3 compliance and REACH unaffected status. Regulatory requirements are met equally by either part.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is valid when the following parameters match: varistor voltage range (405-495 V), surge current rating (1.2 kA), energy absorption (23 J), operating temperature range (-55°C to 85°C), and capacitance at 1 MHz (80 pF).

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process can accommodate the packaging format. Both parts use identical through-hole disc 7mm form factors and mount identically on circuit boards. Packaging format selection depends on assembly equipment capabilities.
