V175LS5 Equivalent & Substitute Parts

Part Overview

The V175LS5 is a 270 V, 2.5 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc package (20mm). This component is designed for transient voltage protection in electronic circuits with a maximum DC voltage rating of 225 V and operating temperature range of -55°C to 85°C.

The V175LS5 is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this specific voltage suppression capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V175LS5 is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

• Varistor voltage range (Min/Typ/Max): 243 V / 270 V / 297 V
• Surge current rating: 2.5 kA
• Maximum DC voltage: 225 V
• Maximum AC voltage: 175 V
• Energy dissipation: 30 J
• Capacitance @ 1 MHz: 350 pF
• Operating temperature: -55°C to 85°C
• Mounting type: Through Hole
• Package: Disc 20mm
• RoHS3 compliance

The V175LS5P meets all electrical and mechanical parameters identical to the main part. The primary distinction is packaging format (Cut Tape vs. bulk inventory) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The V175LS5P is the direct electrical and mechanical equivalent of the V175LS5. All critical electrical parameters—varistor voltage, surge current, DC/AC voltage ratings, energy dissipation, and capacitance—are identical. Both components are RoHS3 compliant with MSL 1 rating.

The V175LS5P carries Active product status, ensuring ongoing manufacturer support and supply availability. The V175LS5, classified as Obsolete, may face supply constraints. For new designs or production continuity, the V175LS5P is the appropriate selection.

The packaging difference (Cut Tape vs. bulk inventory) does not affect electrical performance or board-level compatibility. Selection between these formats depends on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can V175LS5P directly replace V175LS5 in existing designs?

A: Yes. The V175LS5P is electrically and mechanically identical to the V175LS5. All voltage ratings, surge current capacity, energy dissipation, operating temperature range, and package dimensions are equivalent. No circuit redesign is required.

Q: What is the difference between V175LS5 and V175LS5P?

A: The primary differences are product status and packaging format. The V175LS5 is Obsolete with bulk inventory packaging, while the V175LS5P is Active with Cut Tape packaging. Electrical specifications are identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts are RoHS3 compliant, carry MSL 1 rating, and share identical ECCN and HTSUS classifications. Compliance requirements are met by either part.

Q: Does the Cut Tape packaging of V175LS5P affect circuit performance?

A: No. Packaging format does not affect electrical performance or functional characteristics. Cut Tape packaging is a procurement and assembly consideration only.

Q: What parameters must match for a valid substitute?

A: Valid substitutes must maintain identical varistor voltage range (243–297 V), surge current (2.5 kA), DC/AC voltage ratings (225 V / 175 V), energy dissipation (30 J), operating temperature (-55°C to 85°C), and through-hole disc 20mm package configuration.
