Key Parameters

Substitute Part Grouping Explanation

The V660LA10P qualifies as a parametric equivalent to the V660LC10P based on the following substitution criteria:

Electrical Parameters Match:

• Varistor voltage range: 972 V (Min) to 1.188 kV (Max), with 1.08 kV typical
• Surge current rating: 2.5 kA
• Maximum AC voltage: 660 V
• Maximum DC voltage: 850 V
• Energy dissipation: 70 J
• Capacitance: 70 pF @ 1 MHz

Mechanical & Packaging Match:

• Mounting type: Through Hole
• Package: Disc 10mm
• Number of circuits: 1

Compliance & Status Match:

• RoHS3 compliant
• REACH unaffected
• Product status: Active
• Moisture sensitivity level: 1 (Unlimited)

The substitution is based on identical electrical performance specifications and mechanical form factor. The difference between the LC and LA series designations reflects internal manufacturing or design revision classifications within Littelfuse's product line, with no impact on functional equivalence for this application.

Parameter Comparison

Engineering Selection Recommendations

Both the V660LC10P and V660LA10P are active production components from Littelfuse with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain considerations. The V660LA10P currently has higher inventory availability (2301 units) compared to the V660LC10P (692 units). Both parts meet ROHS3 compliance and REACH requirements, making them suitable for regulated applications. The through-hole disc 10mm package ensures compatibility with standard PCB mounting processes. No performance trade-offs exist between the two designations.

Frequently Asked Questions (FAQ)

Q: Can V660LA10P be used as a direct replacement for V660LC10P?

A: Yes. Both parts share identical electrical ratings (1.08 kV typical varistor voltage, 2.5 kA surge current), mechanical packaging (disc 10mm through-hole), and compliance certifications (ROHS3, REACH unaffected). The series designation change (LC to LA) does not affect functional equivalence.

Q: Are there any differences in operating temperature range between these parts?

A: No. Both parts operate across the same temperature range of -55°C to 85°C.

Q: Do both parts have the same capacitance characteristics?

A: Yes. Both the V660LC10P and V660LA10P have 70 pF capacitance measured at 1 MHz.

Q: What is the significance of the series designation change from LC to LA?

A: The series designation reflects internal manufacturing or design revision classifications within Littelfuse's product portfolio. This change does not impact electrical performance, mechanical form factor, or compliance status.

Q: Are moisture sensitivity levels identical?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use identical through-hole mounting with disc 10mm packaging, allowing direct substitution in existing PCB designs without layout modifications.
