Key Parameters

Substitute Part Grouping Explanation

The V320LT7P qualifies as a parametric equivalent to the V320LU7P based on identical electrical and mechanical specifications. Substitution is valid when the following criteria are met:

• Varistor voltage range (Min/Typ/Max): 459 V / 510 V / 561 V
• Surge current rating: 1.2 kA
• Maximum AC and DC voltage ratings: 320 V AC / 420 V DC
• Energy dissipation: 25 J
• Physical form factor: Disc 7mm through-hole
• Operating temperature range: -55°C to 85°C
• Number of circuits: 1
• Capacitance specification: 65 pF @ 1 MHz

The only difference between these parts is packaging format: V320LU7P is supplied in Tape & Reel (TR) format, while V320LT7P is supplied in Cut Tape (CT) format. Both maintain identical component performance and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both V320LU7P and V320LT7P are active products with identical electrical performance and full regulatory compliance. Selection between these parts is determined by procurement and assembly requirements:

• V320LU7P (Tape & Reel format) is suitable for high-volume automated assembly operations requiring continuous tape feed.
• V320LT7P (Cut Tape format) is suitable for lower-volume applications, manual assembly, or when tape reel handling infrastructure is unavailable.

Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level 1 indicates unlimited shelf life under standard storage conditions for both variants.

Frequently Asked Questions (FAQ)

Q: Can V320LT7P replace V320LU7P in production?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. V320LT7P (Cut Tape) can replace V320LU7P (Tape & Reel) provided assembly equipment can accommodate cut tape input.

Q: Are there any performance differences between these substitutes?

A: No. Varistor voltage, surge current rating, energy dissipation, operating temperature range, and all other electrical specifications are identical. Performance in circuit operation is equivalent.

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

A: Tape & Reel (TR) supplies components on continuous tape wound on a reel, optimized for automated pick-and-place equipment. Cut Tape (CT) supplies components on tape segments, suitable for manual handling or equipment without reel capability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both V320LU7P and V320LT7P are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level is 1 (unlimited shelf life) for both.

Q: Which part should I select for my application?

A: Selection depends on your assembly process. For automated high-volume production, V320LU7P (Tape & Reel) is standard. For manual assembly or lower volumes, V320LT7P (Cut Tape) may be more practical. Electrical performance is identical.
