Substitute Part Grouping Explanation

Substitution for the V275LU2P is based on electrical parameter equivalence and mechanical compatibility. The substitute part V275LS2P maintains identical electrical specifications across all critical parameters: maximum AC/DC voltage ratings, varistor voltage range (405V minimum to 495V maximum), surge current capacity (1.2 kA), energy dissipation (23J), capacitance (80 pF @ 1 MHz), and operating temperature range (-55°C to 85°C). The primary difference is packaging format: V275LU2P is supplied in Tape & Reel (TR) configuration, while V275LS2P is supplied in Cut Tape (CT) configuration. Both components share identical series classification within the Littelfuse LU/LS product line, through-hole mounting, and disc 7mm form factor. Substitution is valid when packaging format does not constrain assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

Both V275LU2P and V275LS2P are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on assembly process requirements. The V275LU2P in Tape & Reel format is suitable for automated pick-and-place assembly operations. The V275LS2P in Cut Tape format accommodates manual assembly or lower-volume production workflows. Both parts carry identical electrical performance specifications and environmental certifications, making them functionally interchangeable at the circuit level. Inventory availability should be evaluated based on procurement timeline: V275LU2P has 3200 units in stock, while V275LS2P has 11160 units in stock.

Frequently Asked Questions (FAQ)

Q: Can V275LS2P replace V275LU2P in my circuit design? A: Yes. Both parts are electrically identical across all specified parameters including voltage ratings, surge current capacity, energy dissipation, and operating temperature range. Substitution is valid provided your assembly process can accommodate Cut Tape (CT) packaging instead of Tape & Reel (TR) format.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on a reel, optimized for automated assembly equipment. Cut Tape (CT) packaging supplies the same components on tape segments, suitable for manual assembly or lower-volume production. Both formats contain identical components with the same electrical specifications.

Q: Are there any compliance or certification differences between these parts? A: No. Both V275LU2P and V275LS2P carry identical certifications: ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Which part should I select based on availability? A: V275LS2P has higher current inventory (11160 units) compared to V275LU2P (3200 units). If supply chain continuity is a priority, V275LS2P offers greater stock availability, provided your assembly process supports Cut Tape format.

Q: Do these parts have identical physical dimensions? A: Yes. Both components use identical Disc 7mm package form factor and through-hole mounting configuration, ensuring mechanical compatibility in PCB layouts designed for either part.
