Key Parameters

Substitute Part Grouping Explanation

The V680LC10P has one parametric equivalent: V680LA10P. This substitute relationship is established based on identical electrical and mechanical parameters across all critical specifications:

• Maximum AC voltage rating: 680 V
• Maximum DC voltage rating: 875 V
• Varistor voltage range: 990 V (Min) to 1.21 kV (Max), with 1.1 kV typical
• Surge current capacity: 2.5 kA
• Energy absorption: 75 J
• Operating temperature range: -55°C to 85°C
• Package form factor: Disc 10mm through-hole
• Capacitance: 65 pF @ 1 MHz
• Number of circuits: 1
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

Both parts belong to the Littelfuse varistor product line and share identical functional characteristics, making them interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the V680LC10P and V680LA10P are active production components from Littelfuse with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and supply chain requirements, as they are electrically and mechanically identical. The V680LA10P offers higher current inventory (4,578 units) compared to the V680LC10P (796 units), making it a viable alternative when primary part availability is constrained. Both components meet the same regulatory and environmental compliance requirements and are suitable for direct substitution in transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can V680LA10P be used as a direct replacement for V680LC10P?

A: Yes. Both parts are manufactured by Littelfuse and share identical electrical specifications, voltage ratings, surge current capacity, energy absorption, operating temperature range, and package form factor. They are direct functional equivalents.

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

A: The LC and LA designations represent different product series within the Littelfuse varistor line. However, the V680LC10P and V680LA10P variants specified here are parametrically identical across all provided electrical and mechanical parameters.

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

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected status, EAR99 ECCN classification, and MSL Rating 1 (Unlimited).

Q: What are the critical parameters for substitution in TVS varistor applications?

A: The critical parameters are maximum AC/DC voltage ratings (680 V AC, 875 V DC), varistor voltage range (990 V to 1.21 kV), surge current capacity (2.5 kA), energy absorption (75 J), operating temperature range (-55°C to 85°C), and package form factor (Disc 10mm through-hole). Both parts match all these specifications.

Q: Is the 10mm disc package compatible with standard through-hole PCB layouts?

A: Yes. Both parts use identical through-hole disc packaging (10mm form factor) and are compatible with standard through-hole PCB designs and assembly processes.
