Key Parameters

Substitute Part Grouping Explanation

Substitution of the V460LA40C is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (typical value of 715 V with tolerance range 644.6 V – 786.5 V)
• Maximum AC voltage specification (460 V)
• Surge current capacity (10 kA)
• Energy absorption rating (430 J)
• Capacitance at 1 MHz (7000 pF)
• Operating temperature range (-55°C to 85°C)
• Through-hole mounting configuration
• Disc 20mm package geometry
• Single-circuit configuration

The V460LA40CP qualifies as a direct substitute based on identical electrical and mechanical specifications across all parameters listed above. The primary distinction between these parts is product status and RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The V460LA40CP is the direct equivalent substitute for the V460LA40C. Both components maintain identical electrical performance and mechanical specifications across all critical parameters. The V460LA40CP is preferred for new designs and ongoing applications due to its active product status and ROHS3 compliance certification. The V460LA40C, being obsolete, should be replaced with V460LA40CP in systems requiring component refresh or inventory replenishment. No performance degradation or functional compromise occurs with this substitution.

Frequently Asked Questions (FAQ)

Q: Can V460LA40CP be used as a direct replacement for V460LA40C in existing circuits?

A: Yes. The V460LA40CP provides identical electrical and mechanical performance. All voltage ratings, surge current capacity, energy absorption, capacitance, and thermal specifications are equivalent. Direct substitution is possible without circuit modification.

Q: What is the primary difference between V460LA40C and V460LA40CP?

A: The V460LA40CP is the active production variant with ROHS3 compliance certification. The V460LA40C is obsolete. Electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: Both components use identical through-hole disc 20mm packaging. No mechanical or dimensional differences exist.

Q: Why is the V460LA40C listed as obsolete?

A: The V460LA40C has been discontinued by Littelfuse Inc. The V460LA40CP serves as the current production equivalent with the same performance characteristics.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts deliver identical varistor voltage, surge current, and energy absorption specifications.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both components maintain the same operating temperature range of -55°C to 85°C and are suitable for equivalent thermal environments.
