Parameter Comparison

Engineering Selection Recommendations

V275LT4P Selection: This Littelfuse part is a direct parametric equivalent with identical electrical specifications and package configuration. Both parts maintain ROHS3 compliance and are produced by the same manufacturer. Selection of V275LT4P is appropriate when supply availability of the V275LS4P is constrained, as all functional parameters remain unchanged.

B72207S0271K111 Selection: This EPCOS - TDK Electronics part meets the core TVS varistor requirements with matching varistor voltage range, surge current capacity, and through-hole disc 7mm package. The maximum DC voltage specification is 350 V compared to 369 V for the Littelfuse parts, and energy rating is 21 J versus 23 J. Both parts maintain ROHS3 compliance. This substitute is appropriate for applications where the specified DC voltage margin and energy absorption capacity of the B72207S0271K111 are sufficient for the circuit design.

Frequently Asked Questions (FAQ)

Q: Can V275LT4P be used as a direct replacement for V275LS4P?

A: Yes. V275LT4P is a parametric equivalent with identical electrical specifications, including varistor voltage range (387-473 V typical 430 V), surge current capacity (1.2 kA), energy rating (23 J), and through-hole disc 7mm package configuration. Both are manufactured by Littelfuse Inc. and maintain ROHS3 compliance.

Q: What are the key differences between V275LS4P and B72207S0271K111?

A: Both parts share identical varistor voltage range (387-473 V typical 430 V), surge current capacity (1.2 kA), and through-hole disc 7mm package. Differences include: maximum DC voltage (369 V vs. 350 V), energy rating (23 J vs. 21 J), operating temperature range (-55 to 85°C vs. -40 to 105°C), and manufacturer (Littelfuse vs. EPCOS - TDK Electronics).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. V275LS4P, V275LT4P, and B72207S0271K111 are all ROHS3 compliant and REACH unaffected.

Q: Does package compatibility affect substitution?

A: No. All listed parts use identical through-hole disc 7mm packaging, ensuring mechanical and electrical compatibility on PCB layouts designed for the V275LS4P.

Q: Which substitute should be selected for maximum operating temperature requirements?

A: B72207S0271K111 supports an operating temperature range of -40 to 105°C, compared to -55 to 85°C for both Littelfuse parts. Selection depends on the specific thermal requirements of the application circuit.
