V140LC5P Equivalent & Substitute Parts

Part Overview

The V140LC5P is a 220 V, 2.5 kA varistor manufactured by Littelfuse Inc., designed for transient voltage suppression applications. This through-hole disc component (10mm) provides single-circuit protection with 22 J energy rating and operates across -55°C to 85°C. The part maintains Active product status with full ROHS3 compliance and REACH unaffected certification. Substitute parts are identified when electrical and mechanical parameters align within the specified tolerances for this varistor category.

Substitute Part Grouping Explanation

The V140LA5P qualifies as a parametric equivalent to the V140LC5P based on strict alignment of electrical and mechanical specifications. Substitution is valid when the following criteria are met:

• Maximum AC Volts: 140 V (identical)
• Maximum DC Volts: 180 V (identical)
• Varistor Voltage (Typical): 220 V (identical)
• Varistor Voltage Range: 198–242 V (identical)
• Current - Surge: 2.5 kA (identical)
• Energy: 22 J (identical)
• Number of Circuits: 1 (identical)
• Capacitance @ 1 MHz: 400 pF (identical)
• Operating Temperature Range: -55°C to 85°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Disc 10mm (identical)

Both parts belong to the Littelfuse varistor product line and maintain identical electrical performance and physical form factor. The primary difference is the series designation (LC versus LA), which does not affect functional compatibility within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

Both V140LC5P and V140LA5P maintain Active product status with identical compliance certifications (ROHS3, REACH Unaffected, EAR99). Selection between these parts is based on availability and supply chain considerations rather than technical differentiation. The V140LA5P series currently maintains higher inventory levels (9279 pcs versus 787 pcs for V140LC5P), which may influence procurement decisions. Both parts satisfy identical electrical and mechanical requirements for 220 V transient voltage suppression applications with 2.5 kA surge current capacity.

Frequently Asked Questions (FAQ)

Q: Can V140LA5P replace V140LC5P in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including voltage ratings, surge current capacity, energy dissipation, operating temperature range, and physical form factor (Disc 10mm through-hole).

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 functional performance or compatibility. Both series meet identical electrical specifications for this 220 V varistor application.

Q: Are there any compliance or certification differences? A: No. Both parts carry identical certifications: ROHS3 Compliant, REACH Unaffected, EAR99 classification, and HTSUS code 8533.40.4000. Moisture Sensitivity Level is 1 (Unlimited) for both.

Q: What parameters must remain constant for substitution? A: Varistor voltage (220 V typical, 198–242 V range), maximum AC/DC ratings (140 V AC, 180 V DC), surge current (2.5 kA), energy rating (22 J), operating temperature (-55°C to 85°C), and physical package (Disc 10mm through-hole).

Q: Can these parts be used interchangeably in PCB designs? A: Yes. Identical through-hole mounting specifications and 10mm disc form factor ensure direct mechanical and electrical interchangeability without design modification.
