Substitute Part Grouping Explanation

Substitution eligibility for the V460LC20AP is determined by matching the following critical parameters:

• Maximum AC Volts: 460 V
• Maximum DC Volts: 615 V
• Varistor Voltage (Typical): 715 V
• Current - Surge: 4.5 kA
• Energy: 100 J
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: Disc 14mm
• Operating Temperature Range: -55°C to 85°C

The V460LA20AP meets all substitution criteria. Both parts are manufactured by Littelfuse Inc., belong to the same product category (Transient Voltage Suppressors), and maintain identical electrical and mechanical specifications. The primary difference is the series designation (LC versus LA), which does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the V460LC20AP and V460LA20AP are active production components from Littelfuse Inc. with identical electrical performance and mechanical specifications. Selection between these parts may be based on inventory availability: the V460LA20AP has 2140 units in stock compared to 696 units for the V460LC20AP. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The series designation difference (LC versus LA) does not impact functional compatibility in transient voltage suppression circuits.

Frequently Asked Questions (FAQ)

Q: Can V460LA20AP replace V460LC20AP in existing designs?

A: Yes. Both parts share identical electrical parameters (715 V typical varistor voltage, 4.5 kA surge current, 100 J energy rating) and mechanical specifications (through-hole mounting, 14mm disc package). The series designation change does not affect circuit performance.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory status is equivalent.

Q: What determines substitution eligibility for this varistor?

A: Substitution is based on matching maximum AC/DC voltage ratings, varistor voltage range, surge current capacity, energy rating, circuit count, operating temperature range, and physical package dimensions. All these parameters must align for functional equivalence.

Q: Does the series designation (LC versus LA) affect performance?

A: No. The series designation reflects internal manufacturing or design revision but does not alter the electrical or mechanical characteristics specified in the datasheet parameters.

Q: Are both parts suitable for the same temperature operating range?

A: Yes. Both parts operate across -55°C to 85°C, making them interchangeable for applications within this thermal envelope.
