Key Parameters

Substitute Part Grouping Explanation

The V320LT7P is classified as a parametric equivalent to the V320LU7PX2855. Substitution is valid based on the following criteria:

Electrical Parameters (Identical):

• Varistor voltage range: 459 V (Min) to 561 V (Max), 510 V (Typical)
• Surge current rating: 1.2 kA
• Maximum AC voltage: 320 V
• Maximum DC voltage: 420 V
• Energy dissipation: 25 J
• Capacitance: 65 pF @ 1 MHz

Mechanical Parameters (Identical):

• Package type: Disc 7mm
• Mounting type: Through Hole
• Number of circuits: 1

Compliance & Status (Identical):

• RoHS3 compliant
• REACH unaffected
• Active production status

Packaging Difference:

• V320LU7PX2855: Tape & Reel (TR)
• V320LT7P: Cut Tape (CT)

The substitution is valid for applications where packaging format flexibility exists. Both parts are from the Littelfuse LU and LT series respectively and share identical electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the V320LU7PX2855 and V320LT7P are active production components from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements:

• V320LU7PX2855 is specified when tape and reel packaging is required for automated assembly processes or high-volume production environments.
• V320LT7P is specified when cut tape packaging is acceptable for manual assembly, lower-volume applications, or when cut tape inventory is preferred.

Both parts deliver identical electrical performance and thermal characteristics across the specified operating range. No functional differences exist between these components.

Frequently Asked Questions (FAQ)

Q: Can V320LT7P replace V320LU7PX2855 in my circuit design?

A: Yes. Both parts have identical electrical specifications including varistor voltage (510 V typical), surge current (1.2 kA), and operating temperature range (-55°C to 85°C). The only difference is packaging format: tape and reel versus cut tape.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is used for automated pick-and-place assembly on production lines. Cut Tape (CT) packaging provides individual component segments cut from the reel, suitable for manual assembly or lower-volume applications. Both formats contain the same component.

Q: Are both parts RoHS compliant?

A: Yes. Both V320LU7PX2855 and V320LT7P are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Do these parts have the same thermal performance?

A: Yes. Both parts operate across the identical temperature range of -55°C to 85°C and have the same energy dissipation rating of 25 J.

Q: Which part should I select for high-volume manufacturing?

A: The V320LU7PX2855 in tape and reel format is optimized for high-volume automated assembly. The V320LT7P in cut tape format is suitable for lower-volume or manual assembly scenarios.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the same Disc 7mm package and through-hole mounting configuration, ensuring identical PCB footprint and assembly compatibility.
