Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V39ZC1 is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (35.1 V minimum to 42.9 V maximum)
• Surge current capacity (250 A)
• Energy dissipation (1.2 J)
• Mounting configuration (through-hole disc 7mm)
• Number of circuits (1)
• Operating temperature range (-55°C to 85°C)
• Electrical characteristics (capacitance, AC/DC voltage limits)

The V39ZC1P qualifies as a direct substitute based on identical electrical specifications and mechanical form factor. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The V39ZC1P is the direct equivalent substitute for the V39ZC1. Both components share identical electrical and mechanical specifications, including varistor voltage rating, surge current capacity, energy dissipation, and thermal operating range.

The V39ZC1P carries Active product status, ensuring ongoing manufacturer support and supply availability. Both parts maintain ROHS3 compliance and are suitable for applications requiring 39 V transient voltage suppression in through-hole disc 7mm configurations.

Selection between these parts should be based on packaging requirements and supply chain availability. The V39ZC1P in bulk packaging may offer cost advantages for high-volume procurement.

Frequently Asked Questions (FAQ)

Q: Can V39ZC1P be used as a direct replacement for V39ZC1?

A: Yes. The V39ZC1P is electrically and mechanically equivalent to the V39ZC1. All critical parameters—varistor voltage, surge current, energy rating, and package dimensions—are identical. The primary difference is product status (Active vs. Obsolete) and packaging configuration (Bulk vs. Standard).

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

A: Substitution is determined by equivalence in varistor voltage rating (39 V typical), surge current capacity (250 A), energy dissipation (1.2 J), mounting type (through-hole), package form factor (disc 7mm), and operating temperature range (-55°C to 85°C).

Q: Are there compliance or certification differences between V39ZC1 and V39ZC1P?

A: Both parts are ROHS3 compliant. The V39ZC1P includes REACH Unaffected status. Both carry identical ECCN (EAR99) and HTSUS (8533.40.4000) classifications.

Q: What is the significance of the product status difference?

A: The V39ZC1 is classified as Obsolete, indicating discontinued manufacturing. The V39ZC1P is Active, ensuring continued availability and manufacturer support. For new designs or ongoing production, the V39ZC1P is the recommended selection.

Q: Does packaging type affect electrical performance?

A: No. Bulk and standard packaging configurations do not affect electrical characteristics or performance. Packaging selection is based on procurement volume and supply chain requirements.
