Key Parameters

Substitute Part Grouping Explanation

The V460LA7P qualifies as a parametric equivalent to the V460LC7P based on the following criteria:

Electrical Parameters Match:

• Maximum AC Volts: 460 V
• Maximum DC Volts: 615 V
• Varistor Voltage (Typical): 715 V
• Current - Surge: 1.2 kA
• Energy: 37 J
• Capacitance @ 1 MHz: 55 pF

Mechanical Compatibility:

• Mounting Type: Through Hole
• Package / Case: Disc 7mm
• Number of Circuits: 1

Environmental & Compliance Alignment:

• Operating Temperature Range: -55°C to 85°C
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The substitution is valid because all critical electrical performance parameters, mechanical form factors, and compliance certifications are identical between the main part and substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the V460LC7P and V460LA7P are active production components manufactured by Littelfuse Inc. with identical electrical specifications and mechanical packaging. Selection between these parts should be based on:

Availability: The V460LA7P has higher inventory availability (7716 units) compared to the V460LC7P (937 units), making it a viable alternative when supply constraints exist.

Compliance: Both parts meet ROHS3 compliance requirements and are REACH unaffected, ensuring regulatory alignment for applications requiring environmental compliance certification.

Series Designation: The parts differ only in series designation (LC versus LA), which reflects internal Littelfuse manufacturing classifications and does not affect functional performance or interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can V460LA7P be used as a direct replacement for V460LC7P?

A: Yes. The V460LA7P is a direct parametric equivalent with identical electrical performance (715 V typical varistor voltage, 1.2 kA surge current, 37 J energy rating) and mechanical compatibility (through-hole, 7mm disc package). Both parts are manufactured by Littelfuse Inc. and meet the same compliance standards.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: maximum AC/DC voltage ratings, varistor voltage range, surge current capacity, energy rating, capacitance, operating temperature range, mounting type, and package form factor. All these parameters are identical between the V460LC7P and V460LA7P.

Q: Are there any differences in compliance or certifications?

A: No. Both parts carry identical compliance certifications: ROHS3 compliant, REACH unaffected, EAR99 ECCN classification, and MSL 1 (unlimited moisture sensitivity level).

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

A: The series designation reflects Littelfuse's internal product line classification. From an engineering perspective, both series share identical electrical and mechanical specifications for this voltage and current rating, making them functionally interchangeable.

Q: Should package orientation or PCB layout be adjusted when substituting these parts?

A: No. Both parts use identical through-hole, 7mm disc packaging, requiring no changes to PCB layout, mounting procedures, or component orientation.
