Key Parameters

Substitute Part Grouping Explanation

Substitution of the V150LC1P is determined by strict equivalence across the following critical parameters:

• Varistor voltage range (225 V – 275 V nominal 250 V)
• Surge current capacity (1.2 kA)
• Energy absorption (13 J)
• Mounting configuration (Through Hole, Disc 7mm package)
• Operating temperature range (-55°C to 85°C)
• Electrical ratings (150 V AC, 200 V DC maximum)
• Compliance certifications (ROHS3, REACH Unaffected)

The V150LA1P meets all these criteria and is classified as a parametric equivalent. The substitution is based solely on identical electrical performance and mechanical compatibility within the specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the V150LC1P and V150LA1P are active production components from Littelfuse Inc. with identical electrical specifications and mechanical configurations. Selection between these parts may be based on inventory availability: the V150LA1P has 4,542 units in stock compared to 1,012 units for the V150LC1P. Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility in applications requiring environmental compliance. The series designation difference (LC versus LA) reflects internal Littelfuse product line organization and does not affect functional performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can the V150LA1P be used as a direct replacement for the V150LC1P?

A: Yes. Both parts are parametric equivalents with identical electrical ratings, surge current capacity, energy absorption, operating temperature range, and package configuration. No circuit modifications are required.

Q: Are there any differences in performance between the LC and LA series?

A: No. The series designation reflects internal product line organization only. Electrical performance and mechanical specifications are identical across all provided parameters.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is based on equivalence across varistor voltage range (225–275 V), surge current (1.2 kA), energy rating (13 J), package type (Disc 7mm through-hole), operating temperature (-55°C to 85°C), and compliance certifications (ROHS3, REACH Unaffected).

Q: Does the package size remain the same for both parts?

A: Yes. Both the V150LC1P and V150LA1P use a Disc 7mm through-hole package, ensuring identical PCB footprint and mounting compatibility.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both parts are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
