ERZ-SF2MK680 Equivalent & Substitute Parts

Part Overview

The ERZ-SF2MK680 is a 68 V, 125 A Transient Voltage Suppressor (TVS) varistor manufactured by Panasonic Electronic Components. This component is designed for surface mount applications using a 2-SMD J-Lead package configuration and provides single-circuit transient voltage suppression in the ZNR® series.

The ERZ-SF2MK680 is classified as obsolete. Locating active equivalent parts is necessary to ensure continued availability for new designs, production restocking, and long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERZ-SF2MK680 is determined by strict equivalence across the following electrical and mechanical parameters:

• Varistor voltage range: 61 V (minimum) to 75 V (maximum), with 68 V typical
• Surge current rating: 125 A
• Maximum AC and DC voltage ratings: 40 V AC / 56 V DC
• Energy dissipation capacity: 2.5 J
• Single-circuit configuration
• Operating temperature range: -40°C to 85°C
• Surface mount MLCV package with 2-SMD J-Lead form factor

The ERZ-VF2M680 meets all of these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ERZ-VF2M680 is the direct equivalent for the obsolete ERZ-SF2MK680. Both parts are manufactured by Panasonic Electronic Components within the ZNR® varistor series and share identical electrical specifications and package configurations.

The ERZ-VF2M680 offers the following advantages for component selection:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status meet current environmental and regulatory requirements
• Identical electrical performance across all specified parameters
• Same surface mount MLCV package and J-Lead form factor for direct PCB compatibility

No design modifications or re-qualification are required when transitioning from ERZ-SF2MK680 to ERZ-VF2M680.

Frequently Asked Questions (FAQ)

Q: Can ERZ-VF2M680 be used as a direct replacement for ERZ-SF2MK680?

A: Yes. The ERZ-VF2M680 is a direct functional equivalent. All electrical parameters, including varistor voltage (68 V typical), surge current (125 A), energy dissipation (2.5 J), and operating temperature range (-40°C to 85°C) are identical. The package configuration (2-SMD J-Lead, Surface Mount MLCV) is also identical, allowing for direct PCB substitution without design changes.

Q: Why is the ERZ-SF2MK680 listed as obsolete?

A: The ERZ-SF2MK680 has been discontinued by Panasonic Electronic Components. The ERZ-VF2M680 remains in active production and serves as the current equivalent part for this voltage and current rating within the ZNR® series.

Q: Are there any compliance differences between these parts?

A: The ERZ-VF2M680 is certified as ROHS3 compliant and REACH unaffected. Both parts share the same ECCN (EAR99) and HTSUS (8533.40.4000) classifications. Compliance documentation should be verified with the manufacturer for specific application requirements.

Q: Will the ERZ-VF2M680 work in existing PCB designs using ERZ-SF2MK680?

A: Yes. The identical package type (2-SMD J-Lead) and mounting configuration (Surface Mount MLCV) ensure mechanical and electrical compatibility with existing PCB layouts. No PCB redesign is necessary.

Q: What is the difference between the base part numbers ERZ-SF2 and ERZ-VF2?

A: The base part numbers indicate different product lines within Panasonic's varistor portfolio. However, for the specific voltage and current ratings of this application (68 V, 125 A), the ERZ-VF2M680 provides complete functional equivalence to the ERZ-SF2MK680.
