Key Parameters

Substitute Part Grouping Explanation

The V275LA2P is identified as a parametric equivalent to the V275LC2P based on the following criteria:

Electrical Equivalence: Both parts maintain identical maximum AC voltage (275 V), maximum DC voltage (369 V), varistor voltage specifications (405 V minimum, 450 V typical, 495 V maximum), surge current rating (1.2 kA), energy absorption capacity (23 J), and capacitance at 1 MHz (80 pF).

Mechanical Compatibility: Both components use identical through-hole mounting with a disc 7mm package form factor, ensuring direct PCB footprint compatibility.

Environmental & Compliance Alignment: Both parts operate across the same temperature range (-55°C to 85°C), carry ROHS3 compliance certification, maintain MSL 1 rating, and share identical REACH and ECCN classifications.

Series Differentiation: The V275LC2P belongs to the LC series, while the V275LA2P belongs to the LA series. This series designation reflects internal manufacturing or design revision differences that do not affect electrical or mechanical performance within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the V275LC2P and V275LA2P are active production components from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts may be based on inventory availability: the V275LC2P has 804 units in stock, while the V275LA2P has 2015 units available. Both parts carry identical electrical ratings, mechanical specifications, and environmental certifications, making either suitable for direct substitution in circuit applications requiring 450 V varistor protection with 1.2 kA surge capacity.

Frequently Asked Questions (FAQ)

Q: Can the V275LA2P replace the V275LC2P in an existing design?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. The series designation (LA versus LC) reflects internal manufacturing differences that do not affect performance within the defined electrical envelope. Direct substitution is valid for through-hole PCB applications.

Q: Are there any differences in the disc 7mm package between these parts?

A: No. Both components use identical through-hole disc 7mm packaging, ensuring equivalent PCB footprint compatibility and mounting procedures.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the V275LC2P and V275LA2P are ROHS3 compliant, REACH unaffected, carry EAR99 ECCN classification, and maintain MSL 1 rating. Compliance certifications are identical.

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

A: Both parts operate across -55°C to 85°C ambient temperature range, with identical thermal performance specifications.

Q: Are the electrical specifications identical between these parts?

A: Yes. Maximum AC voltage (275 V), maximum DC voltage (369 V), varistor voltage range (405–495 V typical 450 V), surge current (1.2 kA), energy absorption (23 J), and capacitance at 1 MHz (80 pF) are identical for both parts.
