Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V14E625 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Maximum AC Volts (625 V), Maximum DC Volts (825 V), and Varistor Voltage nominal (1 kV)
• Surge Current Capacity: 6 kA minimum
• Energy Dissipation: 200 J minimum
• Mounting Configuration: Through Hole mounting type
• Physical Package: Disc 14mm form factor
• Circuit Count: Single circuit (1)
• Environmental Compliance: ROHS3 Compliant, MSL 1

The V14E625P qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. Both parts maintain the same voltage ratings, surge current capacity, energy rating, and physical package dimensions. The primary distinction is product status: V14E625P is Active, whereas V14E625 is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

The V14E625P is the primary substitute for the obsolete V14E625. Both components are manufactured by Littelfuse Inc. within the UltraMOV™ series and maintain identical electrical and mechanical specifications. The V14E625P carries Active product status, ensuring continued availability and manufacturing support.

Selection between these parts should be based on procurement requirements and supply chain considerations. The V14E625P is recommended for new designs and ongoing production due to its Active status. For legacy system maintenance where original part specifications must be preserved, the V14E625P provides full electrical and mechanical compatibility.

Both parts comply with ROHS3 requirements and carry MSL 1 (Unlimited) moisture sensitivity classification, suitable for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can V14E625P be used as a direct replacement for V14E625?

A: Yes. The V14E625P is electrically and mechanically equivalent to the V14E625. Both components share identical voltage ratings (625 V AC / 825 V DC), surge current capacity (6 kA), energy dissipation (200 J), and physical package (Disc 14mm through-hole). The primary difference is product status: V14E625P is Active while V14E625 is Obsolete.

Q: What determines whether a varistor can substitute for the V14E625?

A: Substitution eligibility is determined by equivalence across voltage ratings (625 V AC / 825 V DC / 1 kV nominal), surge current capacity (6 kA), energy rating (200 J), mounting type (through-hole), and physical package (Disc 14mm). All parameters must match or exceed the original specification.

Q: Are there packaging differences between V14E625 and V14E625P?

A: Both parts use identical Disc 14mm through-hole packages. The V14E625 is supplied in standard packaging, while V14E625P is supplied in Bulk packaging. This distinction affects procurement and handling but does not impact electrical or mechanical compatibility.

Q: What is the significance of the Obsolete status for V14E625?

A: Obsolete status indicates that Littelfuse Inc. has discontinued manufacturing of the V14E625. The V14E625P, with Active status, represents the current production equivalent and is recommended for all new procurement and design activities.

Q: Are both parts ROHS3 compliant?

A: Yes. Both V14E625 and V14E625P are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, meeting current environmental and regulatory requirements.
