Substitute Part Grouping Explanation

Substitute parts for the V660LC100BP are identified based on strict electrical and mechanical equivalence. The substitution criteria are:

• Maximum AC voltage rating: 660 V
• Maximum DC voltage rating: 850 V
• Varistor voltage range: 940 V (Min) to 1.1 kV (Max), with 1.02 kV typical
• Surge current capacity: 6.5 kA
• Energy absorption: 250 J
• Mounting configuration: Through Hole
• Physical form factor: Disc 20mm
• Single circuit configuration
• Operating temperature range: -55°C to 85°C
• RoHS3 compliance and MSL 1 rating

The V660LA100BP meets all these criteria and is classified as a parametric equivalent. Both parts are manufactured by Littelfuse Inc. and differ only in internal series designation (LC versus LA), with no impact on electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the V660LC100BP and V660LA100BP are Active products with identical electrical specifications and mechanical form factors. Selection between these parts may be based on inventory availability or supply chain considerations. The V660LA100BP currently has higher inventory (1139 pcs) compared to the V660LC100BP (921 pcs). Both parts carry full RoHS3 compliance and REACH Unaffected status, making them suitable for applications requiring environmental regulatory adherence. The MSL 1 rating indicates no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can V660LA100BP be used as a direct replacement for V660LC100BP?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including voltage ratings, surge current capacity, energy absorption, operating temperature range, and physical form factor. The series designation difference (LA versus LC) does not affect performance or compatibility.

Q: Are there any differences in compliance certifications between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, MSL 1 rating, ECCN classification (EAR99), and HTSUS code (8533.40.4000).

Q: What determines whether a varistor can substitute for the V660LC100BP?

A: A substitute varistor must match the following parameters: 660 V maximum AC rating, 850 V maximum DC rating, 1.02 kV typical varistor voltage (within 940 V to 1.1 kV range), 6.5 kA surge current capacity, 250 J energy absorption, Through Hole mounting, Disc 20mm package, single circuit configuration, and -55°C to 85°C operating temperature range.

Q: Does the 20mm disc form factor affect PCB layout compatibility?

A: The 20mm disc package is a mechanical specification that determines mounting hole spacing and component footprint. Both V660LC100BP and V660LA100BP use identical disc geometry, ensuring PCB layout compatibility without modification.

Q: Are there any temperature or environmental restrictions for these parts?

A: Both parts operate across -55°C to 85°C ambient temperature range with MSL 1 rating, indicating no moisture sensitivity limitations. Storage and handling do not require special environmental controls.
