Substitute Part Grouping Explanation

Substitution eligibility for the V175LC2P is determined by strict equivalence across the following critical parameters:

• Maximum AC Volts: 175 V
• Maximum DC Volts: 225 V
• Varistor Voltage (Typ): 270 V
• Current - Surge: 1.2 kA
• Energy: 15 J
• Number of Circuits: 1
• Capacitance @ 1 MHz: 130 pF
• Operating Temperature Range: -55°C to 85°C
• Mounting Type: Through Hole
• Package / Case: Disc 7mm

The V175LA2P meets all specified electrical and mechanical parameters, qualifying as a parametric equivalent. Both components are manufactured by Littelfuse Inc. and maintain identical performance characteristics within the defined operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the V175LC2P and V175LA2P are active products with identical electrical specifications and mechanical form factors. Selection between these components may be based on inventory availability and supply chain considerations. The V175LA2P (LA series) currently maintains higher inventory levels at 2680 pieces compared to the V175LC2P (LC series) at 699 pieces. Both components satisfy RoHS3 compliance requirements and REACH regulatory obligations, ensuring compatibility with modern manufacturing and environmental standards. The identical MSL rating of 1 (Unlimited) indicates equivalent moisture handling characteristics for storage and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the V175LA2P directly replace the V175LC2P in existing designs?

A: Yes. The V175LA2P is a parametric equivalent with identical electrical ratings (175 V AC, 225 V DC, 270 V typical varistor voltage, 1.2 kA surge current, 15 J energy) and mechanical specifications (through-hole mounting, 7mm disc package). Both components are manufactured by Littelfuse Inc. and meet the same compliance standards.

Q: What is the difference between the LC and LA series designations?

A: The LC and LA designations identify different product series within the Littelfuse varistor portfolio. Both series share identical electrical performance and mechanical compatibility for this voltage and current rating. The series designation does not affect substitution eligibility when all electrical and mechanical parameters are equivalent.

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

A: No. Both the V175LC2P and V175LA2P carry identical certifications: RoHS3 compliance, REACH unaffected status, MSL 1 (Unlimited), and EAR99 export classification. They are functionally interchangeable from a regulatory and compliance perspective.

Q: What factors should determine component selection between these two parts?

A: Selection should be based on inventory availability, lead time requirements, and supply chain logistics. Both components are active products with equivalent performance. The V175LA2P currently offers higher stock availability, which may reduce procurement lead times for new orders or replenishment cycles.

Q: Is the 130 pF capacitance specification critical for substitution?

A: Yes. The capacitance value at 1 MHz is a specified electrical parameter that must match for direct substitution. Both the V175LC2P and V175LA2P maintain 130 pF at 1 MHz, confirming electrical equivalence in high-frequency transient suppression applications.
