Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 0071.1561.T2 is determined by the following critical parameters:

• Varistor Voltage Range: The substitute must operate within the specified voltage window (minimum 212 V, typical 235.5 V, maximum 259 V for the original part)
• Surge Current Rating: The substitute must support 6.5 kA surge current capacity
• Package Configuration: The substitute must use a through-hole disc 14mm package for mechanical and electrical compatibility
• Number of Circuits: Single circuit configuration required
• Compliance Standards: RoHS3 compliance and REACH unaffected status maintained

The Littelfuse V150LA10CP meets these substitution criteria with a typical varistor voltage of 240 V (within the acceptable range), identical 6.5 kA surge current rating, matching 14mm disc through-hole package, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse V150LA10CP is a direct functional equivalent for the obsolete SCHURTER 0071.1561.T2. Both components maintain identical surge current ratings (6.5 kA), matching package geometry (14mm disc through-hole), and equivalent compliance certifications (ROHS3, REACH unaffected). The varistor voltage specifications overlap within acceptable tolerance windows, with the Littelfuse part rated at 240 V typical versus 235.5 V for the original component. The Littelfuse substitute provides extended low-temperature operating capability (-55°C versus -40°C) and increased energy absorption capacity (100 J versus 84 J), representing equivalent or improved performance characteristics. Active product status of the Littelfuse component ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse V150LA10CP be used as a direct replacement for the SCHURTER 0071.1561.T2?

A: Yes. Both components share identical surge current ratings (6.5 kA), matching 14mm disc through-hole packages, single-circuit configurations, and equivalent compliance certifications. Varistor voltage specifications are within acceptable tolerance windows (240 V typical for Littelfuse versus 235.5 V for SCHURTER).

Q: What are the key differences between these two parts?

A: The Littelfuse V150LA10CP provides extended low-temperature operation (-55°C minimum versus -40°C) and higher energy absorption (100 J versus 84 J). Varistor voltage ranges overlap with minimal deviation. The Littelfuse part maintains active product status, ensuring supply availability.

Q: Are there any mechanical compatibility concerns?

A: No. Both components use identical 14mm disc through-hole packages, ensuring mechanical and electrical compatibility in existing PCB layouts and mounting configurations.

Q: What compliance certifications apply to the substitute part?

A: The Littelfuse V150LA10CP maintains ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original SCHURTER component.

Q: Why is the SCHURTER part listed as obsolete?

A: Obsolete status indicates the component is no longer manufactured or supported by SCHURTER. The Littelfuse V150LA10CP provides functional equivalence with active product status and ongoing supply chain support.
