Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V140LC2P are qualified based on the following critical parameters that determine functional equivalence:

• Voltage Rating: Maximum AC volts (140 V) and maximum DC volts (180 V) must match exactly
• Varistor Voltage: Typical voltage of 220 V with acceptable range (198 V to 242 V)
• Surge Current Capability: 1.2 kA minimum requirement
• Circuit Configuration: Single circuit (1 circuit)
• Mounting and Package: Through-hole mounting with disc 7mm form factor
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The B72207S0141K101 from EPCOS - TDK Electronics meets all these critical substitution criteria and is therefore qualified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the V140LC2P and B72207S0141K101 are active production parts with full ROHS3 compliance and REACH unaffected status. The B72207S0141K101 is manufacturer-recommended as an equivalent substitute and carries significantly higher inventory availability (8,294 pieces in stock versus 1,002 pieces for the V140LC2P). Both parts meet identical electrical specifications for voltage rating, surge current capability, and circuit configuration. Selection between these parts should be based on supply chain requirements, lead time considerations, and inventory optimization objectives.

Frequently Asked Questions (FAQ)

Q: Can the B72207S0141K101 be used as a direct replacement for the V140LC2P in existing designs?

A: Yes. Both parts share identical maximum AC voltage (140 V), maximum DC voltage (180 V), varistor voltage rating (220 V typical), surge current capability (1.2 kA), circuit configuration (1 circuit), and through-hole disc 7mm package. Both are ROHS3 compliant and REACH unaffected.

Q: Are there differences in operating temperature ranges between these parts?

A: The V140LC2P operates from -55°C to 85°C, while the B72207S0141K101 operates from -40°C to 105°C. Application-specific temperature requirements should be evaluated when selecting between these parts.

Q: What is the difference in energy rating between these varistors?

A: The V140LC2P is rated at 12 J, while the B72207S0141K101 is rated at 10 J. Both parts meet the same voltage and current specifications; energy rating differences reflect design variations between manufacturers.

Q: Are the capacitance specifications identical?

A: No. The V140LC2P has 160 pF @ 1 MHz, while the B72207S0141K101 has 470 pF @ 1 kHz. These measurements are taken at different frequencies and should be evaluated based on specific circuit requirements.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.40.4000.
