Key Parameters

Substitute Part Grouping Explanation

The V250LA10P is identified as a parametric equivalent to the V250LC10P based on the following substitution criteria:

• Maximum AC voltage rating: 250 V (identical)
• Maximum DC voltage rating: 330 V (identical)
• Varistor voltage range: 351 V (Min) to 429 V (Max), with 390 V typical (identical)
• Surge current capacity: 2.5 kA (identical)
• Energy absorption: 40 J (identical)
• Circuit configuration: 1 circuit (identical)
• Capacitance: 220 pF @ 1 MHz (identical)
• Operating temperature range: -55°C to 85°C (identical)
• Mounting configuration: Through hole (identical)
• Physical package: Disc 10mm (identical)

Both parts belong to the Littelfuse varistor product line and differ only in series designation (LC versus LA), with no impact on electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the V250LC10P and V250LA10P are active production components from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on availability and procurement lead times. The V250LA10P currently has higher inventory availability (1805 units versus 1129 units). Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The through-hole disc 10mm package and moisture sensitivity level 1 rating ensure compatibility in equivalent applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can V250LA10P be used as a direct replacement for V250LC10P?

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 package dimensions.

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

A: The series designation reflects internal Littelfuse product line organization but does not affect electrical performance or mechanical compatibility. Both series meet identical specifications for this voltage and current rating.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and EAR99 export classification.

Q: Can these varistors be used interchangeably in PCB designs?

A: Yes. The identical through-hole disc 10mm package and pin configuration allow direct substitution without PCB layout modification.

Q: Which part should be selected based on current inventory?

A: The V250LA10P has higher current stock availability (1805 units) compared to the V250LC10P (1129 units). Selection should align with procurement timelines and supply chain requirements.

Q: Are operating temperature ranges identical?

A: Yes. Both parts operate across the identical temperature range of -55°C to 85°C.
