V68ZU2P Equivalent & Substitute Parts

Part Overview

The V68ZU2P is a 68V 250A varistor manufactured by Littelfuse Inc., classified as a Transient Voltage Suppressor (TVS) device. This through-hole disc varistor (7mm) is designed for transient voltage protection in electronic circuits. The part is currently active in production with full inventory availability (1011 pcs in stock). Finding equivalent substitute parts is necessary to ensure supply chain flexibility, accommodate different packaging requirements, and maintain design continuity when the primary part becomes unavailable or when alternative packaging formats better suit manufacturing processes.

Key Parameters

Substitute Part Grouping Explanation

The V68ZS2P qualifies as a parametric equivalent to the V68ZU2P based on the following substitution criteria:

Electrical Parameters (Identical):

• Varistor voltage range: 61.2 V (Min) to 74.8 V (Max), with 68 V typical
• Surge current rating: 250 A
• Maximum DC voltage: 56 V
• Maximum AC voltage: 40 V
• Energy dissipation: 3 J
• Capacitance: 910 pF @ 1 MHz
• Single circuit configuration

Mechanical Parameters (Identical):

• Package type: Disc 7mm
• Mounting type: Through Hole

Compliance & Environmental (Identical):

• Operating temperature: -55°C to 85°C
• RoHS3 compliance
• REACH unaffected status
• MSL rating: 1 (Unlimited)

Packaging Difference:

• V68ZU2P: Tape & Reel (TR) format
• V68ZS2P: Cut Tape (CT) format

The substitution is valid because all critical electrical and mechanical parameters are identical. The packaging format difference (TR vs. CT) does not affect electrical performance or mechanical compatibility in the circuit application.

Parameter Comparison

Engineering Selection Recommendations

Both the V68ZU2P and V68ZS2P are active production parts from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and inventory requirements:

V68ZU2P (Tape & Reel): Select when automated assembly processes require continuous reel feeding or when high-volume production demands reel-based component handling. Current inventory: 1011 pcs.

V68ZS2P (Cut Tape): Select when manual assembly, small-batch production, or component kit assembly is required. Cut tape format provides flexibility for lower-volume applications. Current inventory: 63200 pcs.

Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance across all markets. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part.

Frequently Asked Questions (FAQ)

Q: Can V68ZS2P replace V68ZU2P in my circuit design? A: Yes. The V68ZS2P is a direct parametric equivalent with identical electrical performance, voltage ratings, surge current capacity, and operating temperature range. The only difference is packaging format (Cut Tape vs. Tape & Reel).

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly. Cut Tape (CT) packaging provides components on tape segments, typically used for manual assembly or smaller production runs. Both formats contain the same component with identical specifications.

Q: Are there any compatibility issues when switching between V68ZU2P and V68ZS2P? A: No compatibility issues exist. Both parts have identical through-hole mounting specifications, disc 7mm package dimensions, and electrical characteristics. The substitution is direct for circuit applications.

Q: Which part should I choose for my application? A: Selection depends on your manufacturing process. Use V68ZU2P (Tape & Reel) for high-volume automated assembly. Use V68ZS2P (Cut Tape) for manual assembly, prototyping, or low-volume production. Both deliver identical circuit performance.

Q: Do both parts meet the same compliance standards? A: Yes. Both V68ZU2P and V68ZS2P are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). They meet identical regulatory and environmental requirements.

Q: What is the operating temperature range for these parts? A: Both parts operate across -55°C to 85°C ambient temperature range, suitable for industrial and commercial applications.
