Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V385LC10P is determined by strict equivalence across the following critical parameters:

• Maximum AC Volts: 385 V
• Maximum DC Volts: 505 V
• Varistor Voltage (Typical): 620 V
• Current - Surge: 2.5 kA
• Energy: 51 J
• Mounting Type: Through Hole
• Package / Case: Disc 10mm
• Operating Temperature Range: -55°C ~ 85°C
• RoHS Compliance: ROHS3 Compliant

The V385LA10P meets all these criteria and is classified as a parametric equivalent. The primary difference between the two parts is the series designation (LC versus LA), which reflects internal design variations within Littelfuse's product line while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the V385LC10P and V385LA10P are active production components manufactured by Littelfuse Inc. and carry identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and lead time requirements. The V385LC10P currently has 3100 units in stock, while the V385LA10P has 1670 units available. Both parts satisfy the same electrical performance envelope and mechanical interface requirements for through-hole PCB mounting applications requiring 620 V transient voltage suppression at 2.5 kA surge current capacity.

Frequently Asked Questions (FAQ)

Q: Can V385LA10P be used as a direct replacement for V385LC10P?

A: Yes. The V385LA10P is a parametric equivalent with identical electrical ratings, surge current capacity, energy dissipation, operating temperature range, and package dimensions. Both parts are ROHS3 compliant and manufactured by Littelfuse Inc.

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

A: The series designation reflects internal design variations within Littelfuse's varistor product line. From an electrical and mechanical standpoint, both series deliver identical performance specifications for this voltage and current rating.

Q: Are the physical dimensions identical between V385LC10P and V385LA10P?

A: Yes. Both parts use the same Disc 10mm package and through-hole mounting configuration, ensuring identical PCB footprint and lead spacing.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the V385LC10P and V385LA10P carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.

Q: Which part should be selected based on availability?

A: Selection should prioritize current inventory levels and procurement lead times. The V385LC10P has higher stock availability (3100 units) compared to V385LA10P (1670 units). Both parts are active production items with equivalent performance.
