Key Parameters

Substitute Part Grouping Explanation

The V300LA2P qualifies as a parametric equivalent to the V300LC2P based on the following criteria:

• Identical varistor voltage range: 441 V (Min), 490 V (Typ), 539 V (Max)
• Identical surge current rating: 1.2 kA
• Identical maximum AC and DC voltage ratings: 300 V AC, 405 V DC
• Identical energy dissipation: 25 J
• Identical package form factor: Disc 7mm through-hole
• Identical number of circuits: 1
• Identical capacitance specification: 70 pF @ 1 MHz
• Identical operating temperature range: -55°C ~ 85°C
• Identical compliance certifications: ROHS3, REACH Unaffected, EAR99

The substitution is based solely on electrical performance and mechanical compatibility within the specified parameter set. The primary difference is the series designation (LA versus LC) and manufacturer inventory levels.

Parameter Comparison

Engineering Selection Recommendations

Both the V300LC2P and V300LA2P are active production components manufactured by Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: the V300LA2P offers significantly higher stock levels (39,700 units versus 966 units). Both parts meet ROHS3 compliance requirements and carry identical regulatory classifications (REACH Unaffected, EAR99). Direct substitution is supported by complete parameter equivalence across all specified electrical, thermal, and mechanical criteria.

Frequently Asked Questions (FAQ)

Q: Can the V300LA2P be used as a direct replacement for the V300LC2P?

A: Yes. Both parts are manufactured by Littelfuse Inc. and share identical electrical specifications, surge current ratings, voltage thresholds, energy dissipation, operating temperature range, and package form factor. The series designation difference (LA versus LC) does not affect functional compatibility.

Q: What is the difference between the V300LC2P and V300LA2P?

A: The parts are electrically and mechanically equivalent. The primary differences are the series designation and manufacturer inventory levels. Both are ROHS3 compliant, active production components with identical performance parameters.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the V300LC2P and V300LA2P carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. Moisture sensitivity level is identical at MSL 1 (Unlimited).

Q: Can these varistors be used interchangeably in through-hole PCB designs?

A: Yes. Both parts feature identical through-hole mounting specifications and Disc 7mm package dimensions, enabling direct PCB layout compatibility without design modification.

Q: What electrical parameters determine substitution eligibility for this varistor category?

A: Substitution is determined by matching varistor voltage range (441–539 V), surge current capacity (1.2 kA), maximum AC/DC voltage ratings (300 V AC, 405 V DC), energy dissipation (25 J), and operating temperature range (-55°C to 85°C).
