Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V230LA20CP is determined by the following critical parameters:

• Varistor Voltage (Typ): 360 V nominal rating
• Maximum AC Volts: 230 V application voltage
• Mounting Type: Through Hole configuration
• Package / Case: Disc 14mm form factor
• Current - Surge Rating: Minimum 6 kA capability
• Regulatory Compliance: ROHS3 Compliant status

The substitute part B72214S2231K101 meets these core substitution criteria. Both parts share identical varistor voltage ratings (360 V typical), maximum AC voltage (230 V), mounting configuration (through hole), and package geometry (disc 14mm). The substitute maintains ROHS3 compliance and operates within compatible temperature ranges for most industrial applications.

Parameter Comparison

Engineering Selection Recommendations

Both the V230LA20CP and B72214S2231K101 are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The V230LA20CP maintains higher surge current (6.5 kA) and energy dissipation (125 J) ratings. Selection of the original part is appropriate when maximum transient protection capacity is required or when system design margins depend on these higher specifications.

The B72214S2231K101 provides equivalent voltage protection (360 V nominal) with slightly reduced surge current (6 kA) and energy ratings (90 J). This substitute is suitable for applications where the lower surge and energy specifications remain within system protection requirements. The substitute offers extended upper operating temperature capability (-40°C ~ 105°C versus -55°C ~ 85°C), which may be advantageous in elevated ambient environments.

Both parts are mechanically and electrically compatible for through-hole PCB mounting in the disc 14mm package configuration.

Frequently Asked Questions (FAQ)

Q: Can B72214S2231K101 directly replace V230LA20CP in all applications?

A: Direct substitution is possible when the application does not require the full 6.5 kA surge current or 125 J energy dissipation of the original part. Both components provide identical 360 V varistor voltage protection and 230 V maximum AC rating. System design margins must accommodate the substitute's 6 kA surge and 90 J energy specifications.

Q: Are the physical packages identical?

A: Yes. Both parts use through-hole mounting in a disc 14mm package configuration, ensuring mechanical compatibility on PCBs designed for the V230LA20CP.

Q: What are the voltage rating differences?

A: There are no voltage rating differences. Both parts share identical varistor voltage specifications: 324 V minimum, 360 V typical, and 396 V maximum. Maximum AC application voltage is 230 V for both.

Q: How do the energy and surge current ratings differ?

A: The V230LA20CP is rated for 6.5 kA surge current and 125 J energy dissipation. The B72214S2231K101 is rated for 6 kA surge current and 90 J energy dissipation. The substitute provides 92% of the original surge current capacity and 72% of the original energy rating.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both V230LA20CP and B72214S2231K101 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the operating temperature difference?

A: The V230LA20CP operates from -55°C to 85°C. The B72214S2231K101 operates from -40°C to 105°C. The substitute provides a 20°C higher upper temperature limit, suitable for applications in elevated ambient conditions.
