Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V140LC20AP are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Maximum AC Volts: 140 V
• Maximum DC Volts: 180 V
• Varistor Voltage (Typical): 220 V
• Current - Surge: 6.5 kA
• Energy: 75 J
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: Disc 20mm
• Operating Temperature Range: -55°C to 85°C
• RoHS Status: ROHS3 Compliant

The V140LA20AP qualifies as a parametric equivalent because it maintains identical electrical performance characteristics and mechanical form factor, differing only in the internal series designation (LA versus LC). Both parts are manufactured by Littelfuse Inc. and carry active product status with full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the V140LC20AP and V140LA20AP are suitable for direct substitution in applications requiring 220 V varistor protection with 6.5 kA surge capacity. Selection between these parts may be based on inventory availability and procurement lead times, as both maintain identical electrical performance and mechanical compatibility.

The V140LA20AP currently maintains higher inventory availability (2231 pcs) compared to the V140LC20AP (992 pcs), which may influence procurement decisions for high-volume applications or time-sensitive projects.

Both parts carry active product status and full compliance with RoHS3 and REACH regulations, ensuring long-term supply chain viability and regulatory acceptance in target applications.

Frequently Asked Questions (FAQ)

Q: Can the V140LA20AP be used as a direct replacement for the V140LC20AP?

A: Yes. The V140LA20AP is a parametric equivalent with identical electrical specifications (140 V AC maximum, 180 V DC maximum, 220 V typical varistor voltage, 6.5 kA surge current, 75 J energy) and mechanical form factor (through-hole disc 20mm). The parts differ only in series designation (LA versus LC) and are both manufactured by Littelfuse Inc.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts share identical mounting type (through-hole), package dimensions (disc 20mm), operating temperature range (-55°C to 85°C), and compliance certifications (RoHS3, REACH Unaffected). Direct PCB substitution is supported without design modifications.

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

A: The LC and LA designations represent different internal series within the Littelfuse varistor product line. These designations do not affect electrical performance or mechanical compatibility for applications requiring the specified 220 V protection level.

Q: Are both parts suitable for long-term supply chain planning?

A: Yes. Both the V140LC20AP and V140LA20AP maintain active product status with no planned discontinuation. Both carry full RoHS3 and REACH compliance, supporting regulatory requirements across target markets.

Q: What factors should determine part selection between these two equivalents?

A: Selection should be based on current inventory availability, procurement lead times, and supplier preference. The V140LA20AP currently shows higher stock levels (2231 pcs versus 992 pcs), which may provide procurement advantages for immediate or high-volume requirements.
