V175LA10CP Equivalent & Substitute Parts

Part Overview

The V175LA10CP is a 270 V, 6.5 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc package (14mm). This component is designed for transient voltage protection in electronic circuits and is currently in active production status. Finding equivalent substitute parts may be necessary due to supply chain considerations, inventory availability, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V175LA10CP is based on the following critical parameters that must remain consistent:

• Varistor Voltage (Typical): 270 V nominal rating
• Package / Case: Disc 14mm through-hole configuration
• Maximum AC Volts: 175 V rating
• Number of Circuits: Single circuit (1)
• Mounting Type: Through Hole
• RoHS Compliance: ROHS3 Compliant status

The B72214S2171K101 manufactured by EPCOS - TDK Electronics meets these core substitution criteria. While the surge current rating differs (6 kA versus 6.5 kA) and energy dissipation varies (70 J versus 110 J), the varistor voltage, package geometry, and electrical protection class remain aligned for equivalent circuit protection functionality.

Parameter Comparison

Engineering Selection Recommendations

Both the V175LA10CP and B72214S2171K101 are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

The V175LA10CP remains the primary specification when maximum surge current capacity (6.5 kA) and energy dissipation (110 J) are required within the -55°C to 85°C operating range.

The B72214S2171K101 serves as an equivalent substitute when the 6 kA surge current rating and 70 J energy specification are acceptable for the application, with the advantage of an extended upper operating temperature limit to 105°C.

Selection between these parts should be based on specific circuit protection requirements, thermal environment constraints, and surge event severity expectations in the target application.

Frequently Asked Questions (FAQ)

Q: Can the B72214S2171K101 be used as a direct replacement for the V175LA10CP?

A: The B72214S2171K101 is electrically and mechanically compatible as a substitute when the application can tolerate a 6 kA surge current rating (versus 6.5 kA) and 70 J energy dissipation (versus 110 J). Both components share identical varistor voltage ratings (270 V typical), package geometry (Disc 14mm), and mounting configuration (through-hole).

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

A: The primary differences are surge current capacity (6.5 kA versus 6 kA), energy dissipation (110 J versus 70 J), and operating temperature range (-55°C to 85°C versus -40°C to 105°C). The varistor voltage characteristics and package specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the V175LA10CP and B72214S2171K101 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Does the operating temperature range difference affect substitution?

A: The B72214S2171K101 offers a wider operating temperature range (-40°C to 105°C) compared to the V175LA10CP (-55°C to 85°C). If the application operates below -40°C or requires the full -55°C lower limit, the V175LA10CP is required. For applications within -40°C to 85°C, both parts are suitable.

Q: What should determine the choice between these two parts?

A: Selection should be based on the specific surge current magnitude expected in the circuit, the thermal environment of the application, and energy dissipation requirements. If surge events exceed 6 kA or the application requires operation below -40°C, the V175LA10CP is the appropriate choice.
