Substitute Part Grouping Explanation

Substitution of the V460LA7 is determined by strict equivalence across the following critical parameters:

• Maximum AC Volts: 460 V
• Maximum DC Volts: 615 V
• Varistor Voltage (Typical): 715 V
• Current - Surge: 1.2 kA
• Energy: 37 J
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: Disc 7mm
• Operating Temperature Range: -55°C to 85°C

The V460LA7P is identified as a direct substitute. Both parts share identical electrical specifications and mechanical form factors. The primary distinction is product status: V460LA7 is obsolete, while V460LA7P is active production. The V460LA7P is supplied in bulk packaging, whereas the original part number does not specify packaging type.

Parameter Comparison

Engineering Selection Recommendations

The V460LA7P is the direct equivalent for the obsolete V460LA7. Both components meet ROHS3 compliance requirements and carry identical electrical and mechanical specifications. The V460LA7P is in active production status, ensuring availability for new designs and replacement applications.

Selection of V460LA7P over V460LA7 is appropriate for all applications requiring the specified voltage, surge current, and energy ratings. The active production status of V460LA7P provides supply chain continuity and eliminates obsolescence risk.

Frequently Asked Questions (FAQ)
