Key Parameters

Substitute Part Grouping Explanation

Substitution of the V480LA10 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Varistor voltage (typical) of 750 V with tolerance range 675 V – 825 V
• Surge Current Capacity: 2.5 kA minimum
• Energy Dissipation: 60 J
• Package Configuration: Through-hole disc 10mm form factor
• Electrical Characteristics: Single circuit, 120 pF capacitance @ 1 MHz
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The V480LA10P is a direct equivalent substitute manufactured by Littelfuse Inc. It maintains identical electrical specifications, package geometry, and environmental ratings. The primary distinction is product status: V480LA10P is active production, whereas V480LA10 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The V480LA10P is the direct substitute for the obsolete V480LA10. Both parts are manufactured by Littelfuse and share identical electrical and mechanical specifications across all critical parameters.

Selection of V480LA10P is appropriate for:

• Direct replacement in existing designs using V480LA10
• New production applications requiring 750 V, 2.5 kA TVS varistor protection
• Applications requiring ROHS3 compliance and MSL 1 rating
• Through-hole assembly processes with disc 10mm package compatibility

The active production status of V480LA10P ensures long-term availability and supply chain continuity compared to the obsolete V480LA10.

Frequently Asked Questions (FAQ)

Q: Can V480LA10P be used as a direct replacement for V480LA10?

A: Yes. V480LA10P is electrically and mechanically equivalent to V480LA10. All voltage ratings, surge current capacity, energy dissipation, package dimensions, and environmental specifications are identical. The primary difference is product status: V480LA10P is in active production.

Q: What determines substitution eligibility for this TVS varistor?

A: Substitution is determined by matching the following parameters: varistor voltage rating (750 V typical, 675 V – 825 V range), surge current capacity (2.5 kA), energy dissipation (60 J), through-hole disc 10mm package configuration, single-circuit design, and environmental compliance (ROHS3, MSL 1).

Q: Are there packaging differences between V480LA10 and V480LA10P?

A: Both parts use identical through-hole disc 10mm packaging. V480LA10P is supplied in bulk packaging, while V480LA10 packaging details are not specified in the available data. The physical component form factor and PCB mounting interface are identical.

Q: What is the operating temperature range for these parts?

A: Both V480LA10 and V480LA10P operate across -55°C to 85°C ambient temperature range, suitable for industrial and commercial electronic applications.

Q: Are both parts RoHS compliant?

A: Yes. Both V480LA10 and V480LA10P are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited), meeting environmental and regulatory requirements for electronic component manufacturing and assembly.
