G6000AS Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The Bourns G6000AS is a 2-pole surface mount gas discharge tube (GDT) rated for 200V DC spark-over voltage with 2000A (2kA) impulse discharge current capacity. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The G6000AS provides overvoltage protection in applications requiring dual-pole transient suppression with SMD mounting compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the G6000AS is determined by the following critical parameters:

• Voltage Rating (DC Spark Over): The substitute must operate within the application's overvoltage protection threshold
• Impulse Discharge Current: The substitute must handle the peak transient current without degradation
• Number of Poles: The substitute must match the circuit topology requirement (2-pole configuration)
• Mounting Type: Surface mount compatibility is required for PCB integration
• Fail Mode: Non-fail-short characteristic must be maintained for circuit safety
• Compliance: RoHS3 and REACH compliance ensures regulatory alignment

The identified substitutes are Bourns 2031-23T-SM-RPLF and 2030-23T-SM-RPLF. Both are active-status components from Bourns with surface mount packaging and equivalent compliance certifications. However, each presents distinct electrical parameter variations that affect application suitability.

Parameter Comparison

Engineering Selection Recommendations

2031-23T-SM-RPLF Consideration: This part maintains the 2-pole configuration required for the G6000AS circuit topology. The voltage rating is 15V lower (185V vs. 200V), and the impulse discharge current is 50% lower (1kA vs. 2kA). Selection of this substitute requires verification that the application's overvoltage threshold and transient current levels are compatible with these reduced ratings. The MSL rating of 1 (Unlimited) provides superior moisture handling compared to the original part's MSL 3 specification.

2030-23T-SM-RPLF Consideration: This part provides higher impulse discharge current capacity (4kA vs. 2kA) and operates at 185V spark-over voltage. However, it is configured as a 3-pole device, which does not match the 2-pole topology of the G6000AS. This part is suitable only for applications where 3-pole protection is acceptable or required. The MSL rating of 1 (Unlimited) exceeds the original part's moisture sensitivity performance.

Both substitutes are active-status products with ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The choice between these parts depends on circuit topology requirements and electrical parameter compatibility with the target application.

Frequently Asked Questions (FAQ)

Q: Can the 2031-23T-SM-RPLF directly replace the G6000AS?

A: The 2031-23T-SM-RPLF maintains the 2-pole configuration and surface mount packaging of the G6000AS. However, the voltage rating is 15V lower (185V vs. 200V) and the impulse discharge current is 50% lower (1kA vs. 2kA). Direct substitution is valid only if the application's overvoltage threshold and transient current requirements are compatible with these reduced electrical parameters.

Q: Why is the 2030-23T-SM-RPLF listed as a substitute if it has 3 poles?

A: The 2030-23T-SM-RPLF is listed as a substitute option for applications where 3-pole protection is acceptable or required. It is not a direct replacement for 2-pole circuit topologies. This part offers higher impulse discharge current capacity (4kA) and is suitable for different circuit configurations than the G6000AS.

Q: What is the significance of the MSL rating difference?

A: The G6000AS has an MSL rating of 3 (168 Hours), while both substitute parts have an MSL rating of 1 (Unlimited). MSL 1 indicates superior moisture resistance and eliminates the 168-hour floor-life limitation. This provides greater flexibility in storage, handling, and manufacturing processes.

Q: Are all three parts RoHS3 compliant?

A: Yes. The G6000AS, 2031-23T-SM-RPLF, and 2030-23T-SM-RPLF are all ROHS3 compliant and REACH unaffected, ensuring regulatory alignment across all options.

Q: What packaging formats are available for the substitute parts?

A: The 2031-23T-SM-RPLF is supplied in Cut Tape (CT) & Digi-Reel® packaging. The 2030-23T-SM-RPLF is supplied in Tape & Reel (TR) packaging. Both formats are standard for surface mount component distribution.
