Key Parameters

Substitute Part Grouping Explanation

The V175LC20AP has one parametric equivalent substitute: the V175LA20AP. Both parts are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications that determine substitutability:

• Maximum AC Volts: 175 V (identical)
• Maximum DC Volts: 225 V (identical)
• Varistor Voltage Range: 243 V (Min) to 297 V (Max), 270 V (Typ) (identical)
• Current - Surge: 6.5 kA (identical)
• Energy: 90 J (identical)
• Number of Circuits: 1 (identical)
• Capacitance @ Frequency: 1400 pF @ 1 MHz (identical)
• Operating Temperature: -55°C to 85°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Disc 20mm (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The primary difference between these parts is the series designation (LC versus LA), which reflects internal design variations within Littelfuse's product line while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the V175LC20AP and V175LA20AP are active production components from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on supply chain availability and inventory levels. The V175LA20AP currently has higher inventory availability (4400 pcs) compared to the V175LC20AP (1108 pcs), making it a viable alternative for procurement planning. Both parts meet identical electrical performance requirements and are suitable for direct substitution in through-hole PCB applications requiring 270 V transient voltage suppression at 6.5 kA surge current capacity.

Frequently Asked Questions (FAQ)

Q: Can the V175LA20AP be used as a direct replacement for the V175LC20AP?

A: Yes. Both parts share identical electrical specifications (175 V AC maximum, 225 V DC maximum, 270 V typical varistor voltage, 6.5 kA surge current, 90 J energy rating) and mechanical specifications (through-hole mounting, 20mm disc package). The series designation difference (LC versus LA) does not affect functional compatibility.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Both are active production components from Littelfuse Inc.

Q: What is the primary reason to consider the V175LA20AP as a substitute?

A: Supply chain continuity and inventory availability. The V175LA20AP has significantly higher stock levels (4400 pcs) compared to the V175LC20AP (1108 pcs), making it a practical alternative for procurement and production planning.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the same temperature range of -55°C to 85°C (TA).

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Both parts use identical through-hole mounting in a 20mm disc package, allowing direct PCB footprint compatibility without design modifications.
