Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V275LC20CP are qualified based on the following criteria:

Electrical Compatibility:

• Varistor voltage range: 387 V (Min) to 473 V (Max)
• Maximum AC voltage rating: 275 V
• Through-hole mounting configuration
• Single circuit design

Mechanical Compatibility:

• Through-hole mounting type
• Disc package format

Regulatory Compliance:

• RoHS3 Compliant status
• REACH Unaffected classification

The substitute parts listed below meet these core substitution parameters. Variations in surge current capacity (6 kA to 10 kA), energy absorption (110 J to 303 J), and package dimensions (14mm to 21.5mm disc) are noted in the comparison table and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain RoHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the V275LC20CP.

B72214S2271K101 (EPCOS - TDK Electronics): This part provides the closest mechanical compatibility with a 14mm disc package matching the original V275LC20CP. Surge current capacity is 6 kA (0.5 kA lower than the original), and energy absorption is 110 J (35 J lower). Operating temperature range extends to 105°C, providing broader thermal performance. This substitute is suitable for applications where package dimensions are constrained and surge current requirements do not exceed 6 kA.

ERZ-V20D431 (Panasonic Electronic Components): This part features enhanced surge current capacity at 10 kA and increased energy absorption at 303 J, providing higher transient protection margins. The package is a larger 21.5mm disc format. Operating temperature range is -40°C to 85°C. This substitute is suitable for applications requiring higher surge current handling and where package size constraints are less restrictive.

ERZ-V20R431 (Panasonic Electronic Components): This part is electrically and mechanically identical to ERZ-V20D431, with the same 10 kA surge current, 303 J energy absorption, and 21.5mm disc package. Both Panasonic variants are suitable for equivalent application scenarios.

Frequently Asked Questions (FAQ)

Q: Can B72214S2271K101 be used as a direct replacement for V275LC20CP?

A: B72214S2271K101 is electrically compatible within the 430 V varistor voltage specification and maintains the same 14mm disc package format. However, surge current capacity is reduced from 6.5 kA to 6 kA, and energy absorption decreases from 145 J to 110 J. Substitution is valid only if application surge current requirements do not exceed 6 kA.

Q: What are the key differences between the Panasonic ERZ-V20D431 and ERZ-V20R431 variants?

A: ERZ-V20D431 and ERZ-V20R431 are electrically and mechanically identical. Both provide 10 kA surge current capacity, 303 J energy absorption, and 21.5mm disc package format. Selection between these two parts may be based on availability or supply chain considerations.

Q: Can the Panasonic ERZ-V20D431 or ERZ-V20R431 be used in place of V275LC20CP?

A: Yes, both Panasonic parts are electrically compatible with matching 430 V varistor voltage specifications. However, the package size increases from 14mm to 21.5mm disc format. Substitution requires verification that the larger package dimensions fit within the available PCB space and mechanical constraints of the application.

Q: How do operating temperature ranges compare across these parts?

A: V275LC20CP operates from -55°C to 85°C. B72214S2271K101 extends to -40°C to 105°C, providing a wider upper temperature range. Both Panasonic parts operate from -40°C to 85°C. For applications requiring operation below -40°C, the V275LC20CP is the only option among these substitutes.

Q: Are all substitute parts RoHS3 and REACH compliant?

A: Yes. V275LC20CP, B72214S2271K101, ERZ-V20D431, and ERZ-V20R431 are all RoHS3 Compliant and REACH Unaffected, meeting equivalent regulatory requirements.
