V175LT20CP Equivalent & Substitute Parts

Part Overview

The V175LT20CP is a 270V 10kA varistor manufactured by Littelfuse in the C-III series. This transient voltage suppressor is designed for through-hole mounting in a 20mm disc package and is currently in active production status. Varistors of this specification are essential components in surge protection circuits where voltage clamping and transient energy absorption are required. Alternative models may be necessary due to inventory availability, packaging format requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V175LT20CP is determined by the following critical parameters:

• Varistor Voltage (Typ): 270 V
• Current - Surge: 10 kA
• Maximum AC Volts: 175 V
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: Disc 20mm
• RoHS Status: ROHS3 Compliant

The B72220S2171K101 manufactured by EPCOS - TDK Electronics meets all core electrical and mechanical requirements for direct substitution. Both parts maintain identical nominal varistor voltage, surge current rating, circuit count, mounting configuration, and package dimensions. Compliance certifications align across both components.

Parameter Comparison

Engineering Selection Recommendations

Both the V175LT20CP and B72220S2171K101 are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Packaging format availability: V175LT20CP is supplied in Cut Tape (CT) format; B72220S2171K101 is supplied in Bulk format
• Operating temperature requirements: The B72220S2171K101 supports an extended upper temperature limit of 105°C compared to 85°C for the V175LT20CP
• Supply chain and inventory considerations: Current stock levels differ between manufacturers

Both components satisfy identical electrical specifications for varistor voltage, surge current capacity, and circuit configuration.

Frequently Asked Questions (FAQ)

Q: Can B72220S2171K101 directly replace V175LT20CP in existing designs?

A: Yes. Both parts maintain identical varistor voltage (270V typical), surge current rating (10kA), and physical package dimensions (Disc 20mm). Electrical performance in surge protection applications is equivalent.

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

A: The V175LT20CP is rated at 220J while the B72220S2171K101 is rated at 135J. This parameter difference does not affect substitution eligibility as both meet the core surge current and voltage specifications.

Q: Are there packaging differences between these parts?

A: Yes. The V175LT20CP is supplied in Cut Tape (CT) packaging, while the B72220S2171K101 is supplied in Bulk packaging. Selection depends on assembly process requirements and handling procedures.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the V175LT20CP and B72220S2171K101 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99.

Q: What is the operating temperature difference?

A: The V175LT20CP operates from -55°C to 85°C, while the B72220S2171K101 operates from -40°C to 105°C. Applications requiring operation above 85°C should use the B72220S2171K101.
