Key Parameters

Substitute Part Grouping Explanation

Substitution for the V07E385 is determined by strict equivalence across all electrical parameters and mechanical form factor. The following criteria establish valid substitutes:

• Varistor voltage range: 558V (Min) to 682V (Max)
• Surge current rating: 1.75 kA
• Energy dissipation: 36 J
• Mounting configuration: Through Hole
• Package form factor: Disc 7mm
• Operating temperature: -55°C to 85°C
• Number of circuits: 1
• Capacitance: 60 pF @ 1 MHz

All substitute parts listed maintain these parameters without deviation. Substitution is further categorized by packaging type (Bulk vs. standard) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and identical electrical specifications. Selection between V07E385P, V07P385, and V07P385P is determined by packaging requirements and inventory availability:

• V07E385P: Direct manufacturer equivalent with bulk packaging and highest inventory (1061 Pcs). Recommended for production volumes requiring bulk tape-and-reel format.
• V07P385: Active equivalent with standard packaging and 850 Pcs inventory. Suitable for applications where standard packaging is specified.
• V07P385P: Active equivalent with bulk packaging and 636 Pcs inventory. Alternative bulk option with lower inventory levels.

All three parts are suitable for direct replacement of the obsolete V07E385 without circuit redesign or performance modification.

Frequently Asked Questions (FAQ)

Q: Can V07E385P, V07P385, and V07P385P be used interchangeably with V07E385?

A: Yes. All substitute parts maintain identical electrical parameters (620V typical varistor voltage, 1.75kA surge current, 36J energy) and mechanical form factor (Disc 7mm through-hole). Substitution is valid for all applications where V07E385 was specified.

Q: What is the difference between standard and bulk packaging?

A: Bulk packaging (designated by "P" suffix) supplies components in tape-and-reel format optimized for automated assembly. Standard packaging supplies components in alternative formats. Electrical and mechanical specifications are identical between packaging types.

Q: Why is V07E385 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. Active equivalents (V07E385P, V07P385, V07P385P) provide continued availability with identical performance characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. V07E385P, V07P385, and V07P385P are all ROHS3 compliant, matching the compliance status of the original V07E385.

Q: Which substitute part should be selected for new designs?

A: Any of the three active equivalents (V07E385P, V07P385, V07P385P) are suitable for new designs. Selection should be based on packaging requirements (bulk vs. standard) and procurement lead times based on current inventory levels.
