V275LC40AP Equivalent & Substitute Parts

Part Overview

The V275LC40AP is a 430 V, 6.5 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc 20mm package. This component is designed for transient voltage protection in electronic circuits and is currently in active production status. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product category, enabling component interchangeability in circuit designs where the original part number may be unavailable or inventory constraints exist.

Substitute Part Grouping Explanation

Substitute parts for the V275LC40AP are identified based on strict electrical and mechanical parameter equivalence within the Littelfuse Transient Voltage Suppressor category. The substitution criteria are:

• Maximum AC Volts: 275 V
• Maximum DC Volts: 369 V
• Varistor Voltage (Typical): 430 V
• Current - Surge: 6.5 kA
• Energy Absorption: 140 J
• Number of Circuits: 1
• Capacitance @ 1 MHz: 900 pF
• Operating Temperature Range: -55°C to 85°C
• Mounting Type: Through Hole
• Package / Case: Disc 20mm
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and are suitable for direct substitution in applications where the V275LC40AP is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts—V275LC40AP, V275LA40AP, and V275LA40APX10—are active production components from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain considerations. All parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use. The parts are suitable for applications requiring 430 V transient voltage suppression with 6.5 kA surge current capacity in through-hole disc 20mm configurations.

Frequently Asked Questions (FAQ)

Q: Can V275LA40AP be used as a direct replacement for V275LC40AP?

A: Yes. Both parts share identical electrical parameters (275 V AC, 369 V DC, 430 V typical varistor voltage, 6.5 kA surge current, 140 J energy absorption) and mechanical specifications (through-hole disc 20mm package, -55°C to 85°C operating range). The difference between LC and LA series designations does not affect functional equivalence for the specified parameters.

Q: What is the difference between V275LA40AP and V275LA40APX10?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The X10 suffix in V275LA40APX10 indicates a packaging or distribution variant. All core performance parameters remain equivalent.

Q: Are these parts suitable for high-temperature applications?

A: All three parts operate within the temperature range of -55°C to 85°C. Applications requiring operation outside this range require alternative component selection.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. V275LC40AP, V275LA40AP, and V275LA40APX10 are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.

Q: Can these varistors be used in AC or DC circuits?

A: These components are rated for both AC and DC applications. Maximum AC voltage is 275 V and maximum DC voltage is 369 V. Circuit design must ensure operating voltages remain within these specified limits.
