SCHURTER 0071.2381.T2 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0071.2381.T2 is a 361.5 V, 10 kA varistor designed for transient voltage suppression in through-hole disc configurations. This component belongs to the AVTP series and is classified as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for system redesign, maintenance, and procurement planning. Substitute parts must maintain electrical performance within the specified voltage and current parameters while meeting the same mechanical and environmental requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 0071.2381.T2 is determined by the following critical parameters:

• Varistor Voltage Range: Nominal voltage must fall within 326 V to 397 V (min to max specification)
• Surge Current Rating: Must support 10 kA minimum
• Mounting Configuration: Through-hole disc format, 20mm package
• Number of Circuits: Single circuit requirement
• Environmental Compliance: ROHS3 compliance and REACH unaffected status
• Operating Temperature: Must support -40°C to 85°C range or broader

The Littelfuse V230LA40CP meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse V230LA40CP is a direct functional substitute for the obsolete SCHURTER 0071.2381.T2. Both components share identical electrical ratings for AC voltage, surge current, and circuit configuration. The varistor voltage specifications are nearly identical, with the Littelfuse part operating within the acceptable tolerance band of the original component.

The Littelfuse substitute offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• Extended operating temperature range (-55°C to 85°C) provides broader environmental compatibility
• Slightly higher energy rating (280 J vs. 270 J) offers enhanced transient suppression capability
• ROHS3 compliance and REACH unaffected status maintain regulatory alignment with the original part

Both components are certified to the same international standards and carry equivalent compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse V230LA40CP be used as a direct replacement for the SCHURTER 0071.2381.T2?

A: Yes. Both parts share identical AC voltage ratings, surge current capacity, circuit count, and mechanical package specifications. Varistor voltage ratings are within acceptable tolerance ranges, and both components meet ROHS3 and REACH compliance requirements.

Q: What is the primary reason for substitution?

A: The SCHURTER 0071.2381.T2 is obsolete. The Littelfuse V230LA40CP is an active product with confirmed availability and supply chain support.

Q: Are there any differences in operating temperature ranges?

A: The Littelfuse substitute supports a wider operating temperature range (-55°C to 85°C) compared to the original part (-40°C to 85°C). This provides additional environmental margin for applications operating at lower temperatures.

Q: How do the energy ratings compare?

A: The Littelfuse part has a 280 J energy rating versus 270 J for the original. This 10 J difference represents enhanced transient suppression capability and does not affect compatibility.

Q: Are both parts available in the same packaging format?

A: Yes. Both the SCHURTER 0071.2381.T2 and Littelfuse V230LA40CP are supplied in through-hole disc 20mm packages, ensuring mechanical compatibility with existing PCB designs.

Q: Do compliance certifications differ between the two parts?

A: No. Both components are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.
