V68ZC2 Equivalent & Substitute Parts

Part Overview

The V68ZC2 is a 68 V, 250 A varistor manufactured by Littelfuse Inc., designed for transient voltage suppression applications. This component features a through-hole disc package (7mm) and is rated for single-circuit protection with 3J energy absorption capability. The V68ZC2 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and procurement planning. The V68ZC2P represents the active production equivalent with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V68ZC2 is determined by strict equivalence across the following critical parameters:

• Varistor voltage range: 61.2 V (Min) to 74.8 V (Max)
• Surge current rating: 250 A minimum
• Energy absorption: 3 J
• Package type: Disc 7mm through-hole
• Number of circuits: 1
• Operating temperature range: -55°C to 85°C

The V68ZC2P qualifies as a direct substitute because it maintains identical electrical performance specifications and mechanical form factor. The primary distinction is product status: V68ZC2 is obsolete, while V68ZC2P is active production.

Parameter Comparison

Engineering Selection Recommendations

The V68ZC2P is the recommended substitute for the obsolete V68ZC2. Both components are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications across all critical parameters. The V68ZC2P carries active product status, ensuring ongoing availability and supply chain continuity.

Both parts comply with ROHS3 requirements and carry EAR99 export classification. Moisture sensitivity level is rated at MSL 1 (Unlimited) for both variants, indicating no special storage or handling requirements.

Selection between these parts should be based on procurement availability and lead time considerations, as electrical performance and physical compatibility are fully equivalent.

Frequently Asked Questions (FAQ)

Q: Can V68ZC2P be used as a direct replacement for V68ZC2?

A: Yes. The V68ZC2P is electrically and mechanically equivalent to the V68ZC2. All critical parameters—varistor voltage, surge current, energy absorption, package dimensions, and operating temperature range—are identical. The primary difference is product status: V68ZC2 is obsolete while V68ZC2P is in active production.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in varistor voltage (61.2 V to 74.8 V range), surge current rating (250 A), energy absorption (3 J), package type (Disc 7mm through-hole), circuit count (1), and operating temperature range (-55°C to 85°C).

Q: Are there any compliance or certification differences between V68ZC2 and V68ZC2P?

A: Both parts are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 1). Both are classified as EAR99 for export purposes. No compliance or certification differences exist between the two variants.

Q: What is the packaging difference between V68ZC2 and V68ZC2P?

A: The V68ZC2 is supplied in standard packaging, while V68ZC2P is supplied in bulk packaging. Both use the same Disc 7mm through-hole form factor. Packaging format does not affect electrical or mechanical compatibility.

Q: Is the V68ZC2P available in the same quantity as the V68ZC2?

A: Inventory levels differ. The V68ZC2 has 1029 pieces in stock (obsolete status), while V68ZC2P has 726 pieces in stock (active production). For new designs or ongoing procurement, V68ZC2P should be specified due to its active product status.
