Substitute Part Grouping Explanation

The V150LS5P has one identified substitute: the V150LT5P. Both parts are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications across all critical parameters. The substitution is valid based on the following criteria:

• Varistor voltage range: 216 V – 264 V (identical)
• Surge current rating: 2.5 kA (identical)
• Energy rating: 25 J (identical)
• Package form factor: Disc 10mm through-hole (identical)
• Operating temperature: -55°C to 85°C (identical)
• Capacitance: 360 pF @ 1 MHz (identical)
• RoHS and compliance status: ROHS3 Compliant (identical)

The only difference between these parts is the packaging format: V150LS5P is supplied in Tape & Reel (TR) format, while V150LT5P is supplied in Cut Tape (CT) format. Both parts belong to different series designations (LS vs. LT) within the Littelfuse varistor product line, reflecting packaging variation rather than functional difference.

Parameter Comparison

Engineering Selection Recommendations

Both V150LS5P and V150LT5P are active production components from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements:

• V150LS5P (Tape & Reel format) is suitable for high-volume automated assembly operations where continuous reel feeding is required.
• V150LT5P (Cut Tape format) is suitable for lower-volume applications, manual assembly, or situations where partial reel quantities are needed.

Both parts carry identical electrical performance, thermal ratings, and compliance certifications. The choice between them does not affect circuit performance or reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can V150LT5P be used as a direct replacement for V150LS5P in production?

A: Yes. Both parts have identical electrical specifications, surge current ratings, varistor voltage characteristics, and operating temperature ranges. The only difference is packaging format (Tape & Reel vs. Cut Tape). Direct substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape packaging supplies components on tape segments, typically used for manual assembly or lower-volume production runs. Both formats contain the same component.

Q: Are there any compliance or certification differences between V150LS5P and V150LT5P?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and ECCN/HTSUS classifications. Compliance and regulatory status are equivalent.

Q: What are the key parameters that define substitution eligibility for this varistor?

A: Substitution eligibility is determined by: varistor voltage range (216–264 V), surge current rating (2.5 kA), energy rating (25 J), package form factor (Disc 10mm), mounting type (through-hole), and operating temperature range (-55°C to 85°C). All these parameters must match for valid substitution.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. From a circuit design perspective, V150LS5P and V150LT5P are functionally identical. Circuit performance, protection characteristics, and reliability are equivalent. Selection is based on manufacturing and supply chain considerations only.
