VC14MT0950KBA Equivalent & Substitute Parts

Part Overview

The VC14MT0950KBA is a 150V 250A varistor manufactured by KYOCERA AVX, designed for transient voltage suppression in surface mount applications. This component operates across a temperature range of -55°C to 125°C and is housed in a 1812 (4532 Metric) package format. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), making it suitable for industrial and commercial electronic applications requiring reliable overvoltage protection.

Identifying equivalent and substitute parts is necessary to ensure supply chain flexibility, manage inventory optimization, and maintain design continuity when the primary part number becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution of the VC14MT0950KBA is determined by strict equivalence across the following critical parameters:

• Varistor Voltage Range: Minimum 135 V, Typical 150 V, Maximum 165 V
• Surge Current Rating: 250 A
• Package Format: 1812 (4532 Metric) surface mount
• Mounting Technology: Surface Mount, MLCV
• Operating Temperature: -55°C to 125°C
• Number of Circuits: Single circuit (1)
• Regulatory Compliance: ROHS3 Compliant

The VJ14MT0950KBA meets all specified parameters and is classified as a parametric equivalent. Both parts share identical electrical characteristics, mechanical dimensions, and environmental ratings, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both VC14MT0950KBA and VJ14MT0950KBA are active production parts manufactured by KYOCERA AVX with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain considerations. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing and storage environments. The VJ14MT0950KBA variant currently has higher inventory availability (2149 pieces) compared to the VC14MT0950KBA (770 pieces), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can VJ14MT0950KBA be used as a direct replacement for VC14MT0950KBA?

A: Yes. Both parts are parametric equivalents with identical varistor voltage ratings (150 V typical), surge current capacity (250 A), package format (1812 / 4532 Metric), and operating temperature range (-55°C to 125°C). No circuit redesign or board layout modification is required.

Q: Are there any differences in package dimensions between these parts?

A: No. Both parts use the 1812 (4532 Metric) surface mount package with MLCV mounting technology. PCB footprints and reflow soldering profiles are identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both VC14MT0950KBA and VJ14MT0950KBA are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), REACH unaffected status, and EAR99 export classification.

Q: What is the primary difference between these two part numbers?

A: The parts are functionally and electrically identical. The difference lies in the manufacturer's internal product line designation (VC versus VJ prefix). Both are produced by KYOCERA AVX and meet identical specifications.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametric equivalents with identical electrical characteristics and package specifications, they can be used interchangeably within the same circuit design and manufacturing process.
