Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V150LS5PX2855 is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (216 V – 264 V range)
• Surge current capacity (2.5 kA minimum)
• Energy absorption (25 J)
• Mounting type (Through Hole)
• Package form factor (Disc 10mm)
• Operating temperature range (-55°C to 85°C)
• Electrical specifications (AC/DC voltage ratings, capacitance)

The V150LT5P qualifies as a parametric equivalent substitute. Both parts are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications. The distinction between these parts is limited to packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. This packaging difference does not affect electrical performance or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the V150LS5PX2855 and V150LT5P are active products with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements:

The V150LS5PX2855 in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding is required. The V150LT5P in Cut Tape format is appropriate for lower-volume applications, manual assembly processes, or situations where partial reel quantities are needed. Both parts deliver identical electrical performance and mechanical fit within the specified circuit application.

Frequently Asked Questions (FAQ)

Q: Can V150LT5P be used as a direct replacement for V150LS5PX2855?

A: Yes. Both parts are electrically and mechanically equivalent. All electrical parameters, including varistor voltage, surge current capacity, energy rating, and operating temperature range are identical. The only difference is packaging format (Tape & Reel versus Cut Tape), which does not affect circuit performance.

Q: What determines if a varistor can substitute for the V150LS5PX2855?

A: Substitution requires matching across all critical parameters: varistor voltage range (216 V – 264 V), surge current (2.5 kA), energy rating (25 J), mounting type (Through Hole), package form (Disc 10mm), and operating temperature range (-55°C to 85°C). Deviations in any of these parameters disqualify a part from substitution.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Cut Tape formats are supply methods only. They do not alter the electrical characteristics, voltage ratings, current capacity, or thermal performance of the varistor component itself.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both V150LS5PX2855 and V150LT5P are RoHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity). Both are classified as active products by Littelfuse Inc.

Q: What is the varistor voltage tolerance for these parts?

A: The varistor voltage tolerance is 216 V minimum to 264 V maximum, with a typical value of 240 V. This 48 V tolerance band (±10% around nominal) is the specified operating window for these components.
