Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 0071.1441.A2 is determined by the following critical parameters:

• Varistor voltage rating (198–242 V range)
• Surge current capacity (4.6 kA minimum)
• Maximum AC voltage (140 V)
• Maximum DC voltage (180 V)
• Through-hole mounting configuration
• Disc 10mm package form factor
• Single-circuit design
• Operating temperature range compatibility (−40 to +85°C minimum)
• RoHS3 compliance

The Littelfuse V140LA5CP meets all substitution criteria within these allowed electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse V140LA5CP is a direct functional substitute for the obsolete SCHURTER 0071.1441.A2. Both components share identical electrical ratings for varistor voltage (220 V nominal), surge current capacity (4.6 kA), and maximum AC voltage (140 V). Both are RoHS3 compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory and trade compliance equivalence.

The Littelfuse substitute offers an extended operating temperature range (−55 to +85°C versus −40 to +85°C), providing additional thermal margin in cold-environment applications. The substitute is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete SCHURTER part.

Physical compatibility is confirmed: both components use identical through-hole mounting and disc 10mm package form factors, allowing direct PCB footprint substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse V140LA5CP be used as a direct replacement for the SCHURTER 0071.1441.A2?

A: Yes. Both components share identical varistor voltage ratings (220 V nominal, 198–242 V range), surge current capacity (4.6 kA), maximum AC voltage (140 V), and package configuration (through-hole disc 10mm). Electrical and mechanical compatibility is confirmed.

Q: What is the difference in energy rating between these parts?

A: The SCHURTER 0071.1441.A2 is rated at 50 J, while the Littelfuse V140LA5CP is rated at 45 J. This 5 J difference represents a minor variation in energy absorption capacity. Application-specific energy requirements should be verified against system transient profiles.

Q: Are there differences in capacitance specifications?

A: Yes. The SCHURTER part specifies 407 pF @ 1 kHz, while the Littelfuse substitute specifies 400 pF @ 1 MHz. The measurement frequencies differ, making direct comparison imprecise. Both values fall within typical varistor capacitance ranges for this voltage class and package size.

Q: Does the extended temperature range of the Littelfuse part affect compatibility?

A: No. The Littelfuse V140LA5CP operating range (−55 to +85°C) encompasses the SCHURTER specification (−40 to +85°C). The extended lower temperature limit provides additional design margin without introducing incompatibility.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the SCHURTER 0071.1441.A2 and Littelfuse V140LA5CP are ROHS3 compliant and REACH unaffected, ensuring equivalent regulatory status for EU and international markets.

Q: What is the product status difference between these parts?

A: The SCHURTER 0071.1441.A2 is obsolete, while the Littelfuse V140LA5CP is in active production. This status difference makes the Littelfuse part the recommended choice for new designs and ongoing system support.
