V250LC2P Equivalent & Substitute Parts

Part Overview

The V250LC2P is a 410 V varistor manufactured by Littelfuse Inc., designed for transient voltage suppression applications. This through-hole disc component (7mm) provides 1.2 kA surge current capacity with 21 J energy rating across a single circuit. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when electrical parameters, mechanical form factor, and compliance certifications remain equivalent, enabling direct replacement in circuit designs without performance degradation.

Key Parameters

Substitute Part Grouping Explanation

The V250LA2P qualifies as a parametric equivalent to the V250LC2P based on the following substitution criteria:

Electrical Parameters (Identical):

• Maximum AC voltage: 250 V
• Maximum DC voltage: 330 V
• Varistor voltage range: 369–451 V (typical 410 V)
• Surge current capacity: 1.2 kA
• Energy rating: 21 J
• Capacitance: 90 pF @ 1 MHz
• Operating temperature range: −55°C to +85°C

Mechanical Parameters (Identical):

• Mounting type: Through Hole
• Package form factor: Disc 7mm
• Number of circuits: 1

Compliance & Certification (Identical):

• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• REACH status: Unaffected
• ECCN: EAR99
• HTSUS code: 8533.40.4000

The only difference between these parts is the internal series designation (LC versus LA), which reflects manufacturing lineage within Littelfuse's varistor product family but does not affect electrical or mechanical performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the V250LC2P and V250LA2P are active production components from Littelfuse Inc. with identical electrical specifications, mechanical form factors, and regulatory compliance profiles. Selection between these parts may be based on inventory availability, lead time, or supply chain considerations, as no technical differentiation exists between them for circuit design purposes.

The V250LA2P currently maintains higher inventory levels (4,319 pcs versus 931 pcs for the V250LC2P), which may influence procurement decisions in applications where supply continuity is a priority.

Both parts satisfy ROHS3 compliance requirements and carry unlimited moisture sensitivity ratings (MSL 1), making them suitable for standard manufacturing and storage conditions without special handling protocols.

Frequently Asked Questions (FAQ)

Q: Can V250LA2P be used as a direct replacement for V250LC2P in existing circuit designs?

A: Yes. All electrical parameters, mechanical dimensions, and compliance certifications are identical. No circuit modifications or re-qualification testing is required for substitution.

Q: What is the difference between the LC and LA series designations?

A: The series designation reflects internal manufacturing lineage within Littelfuse's varistor product family. Both series meet identical electrical and mechanical specifications for this voltage and current rating.

Q: Are there any thermal or environmental performance differences between these parts?

A: No. Both parts operate across the same temperature range (−55°C to +85°C) and carry identical MSL ratings (1 – Unlimited), indicating equivalent performance in thermal and moisture-sensitive environments.

Q: Do these parts require different PCB footprints or mounting procedures?

A: No. Both parts use identical through-hole mounting with 7mm disc packaging. PCB layouts and assembly procedures remain unchanged.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection may be based on current inventory availability, supplier lead times, or established procurement relationships with Littelfuse Inc.
