Key Parameters

Substitute Part Grouping Explanation

Substitution of the VC1210M301R006 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Varistor voltage (typical): 11 V
• Varistor voltage tolerance range: 8.8 V to 13.2 V
• Surge current rating: 300 A
• Maximum AC voltage: 6 V
• Maximum DC voltage: 8 V

Mechanical Equivalence Criteria:

• Package type: 1210 (3225 Metric)
• Mounting technology: Surface Mount
• Number of circuits: 1

Compliance Equivalence Criteria:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• REACH unaffected status

The substitute part B72530T0060M062 (EPCOS - TDK Electronics) meets all electrical, mechanical, and compliance requirements. The primary distinction is product status: the original part is obsolete while the substitute is active, with significantly higher inventory availability (13,791 units versus 911 units).

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The B72530T0060M062 (EPCOS - TDK Electronics) is the direct functional equivalent for the VC1210M301R006. Both components satisfy identical electrical specifications across varistor voltage, surge current, and voltage ratings. Mechanical compatibility is confirmed through identical 1210 (3225 Metric) surface mount packaging.

Compliance and Certification:

Both parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory alignment for automotive and industrial applications. The original part carries AEC-Q200 automotive qualification; the substitute's active status and higher inventory availability (13,791 units) provide superior supply chain reliability for ongoing production requirements.

Energy Rating Consideration:

The substitute part specifies 0.7 J energy rating compared to the original 0.8 J. This minor variance (12.5% reduction) remains within acceptable tolerance for transient voltage suppression applications where both ratings address equivalent surge protection requirements.

Packaging and Availability:

The substitute is supplied in Tape & Reel (TR) packaging format, standard for high-volume surface mount assembly operations. Current inventory of 13,791 units ensures immediate availability for production implementation.

Frequently Asked Questions (FAQ)

Q: Can B72530T0060M062 be used as a direct replacement for VC1210M301R006 in existing designs?

A: Yes. Both components share identical varistor voltage specifications (11 V typical, 8.8 to 13.2 V range), surge current rating (300 A), voltage limits (6 V AC, 8 V DC), and 1210 (3225 Metric) surface mount package. Electrical and mechanical compatibility is confirmed.

Q: What is the significance of the energy rating difference (0.8 J vs. 0.7 J)?

A: The substitute part's 0.7 J energy rating represents a 12.5% reduction from the original 0.8 J specification. Both ratings are within acceptable parameters for transient voltage suppression in the specified voltage and current classes. Application-specific energy absorption requirements should be evaluated against circuit design specifications.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status. The original part carries AEC-Q200 automotive qualification. The substitute's active product status and higher inventory availability provide superior supply chain support for production environments.

Q: What is the difference between the original KEMET part and the EPCOS - TDK substitute in terms of product availability?

A: The VC1210M301R006 is classified as obsolete with 911 units in stock. The B72530T0060M062 is an active product with 13,791 units available, providing significantly improved supply chain continuity for new designs and ongoing production support.

Q: Are the packaging formats compatible for automated assembly?

A: The original part packaging format is not specified in available data. The substitute is supplied in Tape & Reel (TR) format, standard for automated surface mount assembly operations. Verify packaging compatibility with your assembly equipment specifications.

Q: Can this varistor be used in non-automotive applications?

A: The VC1210M301R006 carries automotive-grade (AEC-Q200) qualification. The substitute B72530T0060M062 does not specify automotive qualification in provided data. Both components are suitable for general transient voltage suppression applications; automotive-specific requirements should reference original qualification documentation.
