Substitute Part Grouping Explanation

Substitution for the V460LA10 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: 2.5 kA
• Energy: 56 J
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: Disc 10mm
• Operating Temperature Range: -55°C to 85°C

The V460LA10P is a direct equivalent manufactured by Littelfuse Inc. within the same LA series. This substitute maintains identical electrical specifications and mechanical form factor while offering active product status and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The V460LA10P is the primary substitute for the obsolete V460LA10. Both components are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications across all critical parameters. The V460LA10P offers the advantage of active product status, ensuring continued availability and manufacturing support. Both parts comply with ROHS3 standards and carry MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling.

Selection between these parts should be based on packaging requirements: the V460LA10P is available in bulk packaging, which may provide cost advantages for volume applications. The electrical performance and thermal characteristics remain equivalent, making either part suitable for direct substitution in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the V460LA10P directly replace the V460LA10 in existing designs?

A: Yes. The V460LA10P maintains identical electrical specifications, including 715 V typical varistor voltage, 2.5 kA surge current, and 56 J energy rating. The through-hole disc 10mm package is mechanically identical, allowing direct PCB substitution without layout modifications.

Q: What is the primary reason for substituting the V460LA10?

A: The V460LA10 is classified as obsolete. The V460LA10P provides an active, equivalent alternative from the same manufacturer and series, ensuring continued component availability and manufacturing support.

Q: Are there differences in compliance or certifications between these parts?

A: Both parts are ROHS3 compliant and carry identical MSL 1 ratings. The V460LA10P includes REACH Unaffected status, providing additional regulatory documentation for certain applications.

Q: Does packaging type affect electrical performance?

A: No. The V460LA10 and V460LA10P differ only in packaging format (standard versus bulk). Electrical specifications, thermal performance, and surge handling capacity remain identical regardless of packaging configuration.

Q: What are the operating temperature constraints for these varistors?

A: Both parts operate across the range of -55°C to 85°C ambient temperature. This range applies to all electrical specifications and surge current ratings provided.
