Key Parameters

Substitute Part Grouping Explanation

Substitution of the V250LC10CP is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part V250LA10P qualifies as a parametric equivalent because it maintains identical specifications across the following key criteria:

Voltage specifications: Maximum AC volts (250 V), maximum DC volts (330 V), and varistor voltage range (351 V – 429 V with 390 V typical) are identical.

Surge current rating: Both parts are rated for 2.5 kA surge current capacity.

Energy dissipation: Both parts are rated for 40 J energy handling.

Circuit configuration: Both are single-circuit (1 circuit) devices.

Electrical characteristics: Capacitance at 1 MHz (220 pF) is identical.

Thermal performance: Operating temperature range (-55°C to +85°C) is identical.

Mechanical compatibility: Both use through-hole mounting with identical 10mm disc package dimensions.

Compliance and environmental ratings: Both are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Parameter Comparison

Engineering Selection Recommendations

Both the V250LC10CP and V250LA10P are active production components from Littelfuse Inc. and are fully equivalent for direct substitution. Selection between these parts should be based on inventory availability and supply chain considerations rather than technical performance differences.

Both parts meet ROHS3 compliance requirements and REACH unaffected status, ensuring regulatory compliance in applications subject to environmental and hazardous substance restrictions. The identical MSL 1 (Unlimited) rating indicates both parts have the same moisture handling characteristics and storage requirements.

For applications requiring 390 V varistor voltage protection with 2.5 kA surge capacity in a through-hole disc configuration, either part number provides equivalent performance and reliability.

Frequently Asked Questions (FAQ)
