Key Parameters

Substitute Part Grouping Explanation

Substitution of the V175LS20CP is determined by the following critical parameters:

• Varistor voltage range (243 - 297 V) must be maintained
• Surge current rating of 10 kA minimum
• Through-hole mounting configuration with 20mm disc package
• Single circuit configuration
• RoHS3 compliance and REACH unaffected status

The substitute part B72220S2171K101 meets these core electrical and mechanical requirements. Both parts operate within the same voltage suppression window and handle identical surge current levels. Physical form factor compatibility is confirmed through matching disc 20mm package specifications and through-hole mounting type.

Parameter Comparison

Engineering Selection Recommendations

Both the V175LS20CP and B72220S2171K101 are active production components with full RoHS3 compliance and REACH unaffected status, qualifying them for use in regulated applications.

The V175LS20CP provides 220 J energy absorption capacity. The B72220S2171K101 provides 135 J energy absorption capacity. Selection between these parts depends on the specific energy dissipation requirements of the application circuit.

The B72220S2171K101 operates across a wider temperature range (-40 to 105°C) compared to the V175LS20CP (-55 to 85°C). Applications requiring extended low-temperature operation below -40°C must use the V175LS20CP. Applications requiring extended high-temperature operation above 85°C must use the B72220S2171K101.

Both parts maintain identical varistor voltage specifications (243 - 297 V) and surge current ratings (10 kA), ensuring equivalent transient suppression performance in the circuit.

Frequently Asked Questions (FAQ)

Q: Can B72220S2171K101 be used as a direct replacement for V175LS20CP?

A: Direct replacement is possible when the application operates within the temperature range of -40 to 85°C and the energy absorption requirement does not exceed 135 J. If the application requires the full 220 J energy absorption capacity or operates below -40°C, the V175LS20CP must be used.

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

A: The primary differences are energy absorption capacity (220 J vs. 135 J) and operating temperature range (-55 to 85°C vs. -40 to 105°C). All electrical parameters including varistor voltage and surge current are identical.

Q: Are both parts physically compatible with the same PCB footprint?

A: Yes. Both parts use through-hole mounting with a 20mm disc package configuration, ensuring mechanical compatibility with the same PCB layout.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are RoHS3 compliant and REACH unaffected, meeting identical regulatory standards for restricted substance use.

Q: How is energy absorption capacity relevant to part selection?

A: Energy absorption capacity determines the maximum transient energy the varistor can safely dissipate. Applications with higher transient energy levels require the part with higher energy rating. The V175LS20CP (220 J) is rated for higher energy dissipation than the B72220S2171K101 (135 J).

Q: Which part should be selected for high-temperature applications?

A: The B72220S2171K101 supports operation up to 105°C, making it suitable for high-temperature environments. The V175LS20CP is limited to 85°C maximum operating temperature.
