Key Parameters

Substitute Part Grouping Explanation

The V175LA5P qualifies as a parametric equivalent to the V175LC5P based on the following substitution criteria:

Electrical Parameters (Identical):

• Maximum AC Volts: 175 V
• Maximum DC Volts: 225 V
• Varistor Voltage (Min/Typ/Max): 243 V / 270 V / 297 V
• Current - Surge: 2.5 kA
• Energy: 30 J
• Capacitance @ Frequency: 350 pF @ 1 MHz

Mechanical Parameters (Identical):

• Mounting Type: Through Hole
• Package / Case: Disc 10mm
• Number of Circuits: 1

Compliance & Environmental (Identical):

• Operating Temperature Range: -55°C to 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The only difference between these parts is the internal series designation (LC vs. LA), which does not affect electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the V175LC5P and V175LA5P are active production components from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

Availability: The V175LA5P currently has higher inventory availability (7,260 pcs) compared to the V175LC5P (1,130 pcs), making it suitable for high-volume production requirements.

Compliance: Both parts meet ROHS3 compliance requirements and are REACH unaffected, satisfying regulatory requirements for industrial and consumer applications.

Interchangeability: Direct pin-for-pin and functional substitution is supported without circuit redesign or board layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the V175LA5P be used as a direct replacement for the V175LC5P?

A: Yes. All electrical parameters, mechanical dimensions, and environmental specifications are identical. Direct substitution is supported without circuit modifications.

Q: Are there any differences in performance between the LC and LA series?

A: No. The series designation reflects internal manufacturing processes but does not affect electrical performance, surge current handling, energy absorption, or operating temperature range.

Q: What determines if a varistor can substitute for the V175LC5P?

A: Substitution requires matching of: maximum AC/DC voltage ratings, varistor voltage range (243–297 V), surge current capacity (2.5 kA), energy rating (30 J), through-hole mounting type, and 10mm disc package dimensions.

Q: Are both parts suitable for the same circuit applications?

A: Yes. Identical voltage suppression characteristics, surge current ratings, and thermal operating ranges ensure both parts function identically in transient voltage protection circuits.

Q: Do these parts require any special handling or storage considerations?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
