V175LA5 Equivalent & Substitute Parts

Part Overview

The V175LA5 is a 270 V, 2.5 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc 10mm package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The V175LA5 series provides transient voltage suppression across a single circuit with a nominal varistor voltage of 270 V and surge current capacity of 2.5 kA, suitable for applications requiring overvoltage protection in the 175 V AC / 225 V DC operating range.

Substitute Part Grouping Explanation

Substitution of the V175LA5 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for direct substitution:

Maximum AC Volts: 175 V
Maximum DC Volts: 225 V
Varistor Voltage (Typical): 270 V
Varistor Voltage Range: 243 V – 297 V
Current - Surge: 2.5 kA
Energy: 30 J
Number of Circuits: 1
Capacitance @ 1 MHz: 350 pF
Operating Temperature Range: -55°C to 85°C
Mounting Type: Through Hole

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical equivalence to the V175LA5. Selection among available substitutes should prioritize active product status and inventory availability.

V175LA5P is the primary direct substitute, offering the same LA series designation with active product status and highest inventory availability (7260 units). This part is suitable for immediate replacement in new designs and production.

V175LA5PX2855 and V175LC5CPX1347 are parametric equivalents with active status, differing only in internal manufacturing designations (X2855 and CPX1347 suffixes). Both maintain identical electrical performance and package specifications.

V175LC5P and V175LC5PX2855 represent LC series variants with active status. These parts are parametrically equivalent across all critical specifications and serve as functional alternatives where LC series designation is acceptable.

All substitute parts carry ROHS3 compliance and MSL 1 rating, ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can V175LA5P directly replace V175LA5 in existing designs?

A: Yes. V175LA5P is a direct substitute with identical electrical parameters (175 V AC, 225 V DC, 270 V varistor voltage, 2.5 kA surge current) and package specifications (through-hole disc 10mm). The primary difference is product status (active vs. obsolete) and packaging designation (bulk).

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

A: LA and LC series designations represent different internal manufacturing lines within Littelfuse Inc. All LA and LC variants listed maintain identical electrical and mechanical specifications. Series selection does not affect functional performance in this application.

Q: Are the X2855 and CPX1347 suffix variants functionally equivalent?

A: Yes. These suffixes indicate internal manufacturing or traceability codes and do not alter electrical performance or package specifications. Parts with these designations are parametrically equivalent to their base part numbers.

Q: What inventory considerations apply to substitute selection?

A: V175LA5P offers the highest inventory availability (7260 units), followed by V175LC5PX2855 (1145 units) and V175LC5P (1130 units). Selection should account for lead time and supply chain requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance and MSL 1 rating, meeting current environmental and manufacturing standards.

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

A: Yes. All substitute parts share identical through-hole disc 10mm package specifications, allowing direct PCB footprint compatibility without design modification.
