Bourns G5200AS Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The Bourns G5200AS is a 2-pole surface mount gas discharge tube (GDT) rated for 400 V DC spark over voltage with 2000 A (2 kA) impulse discharge current capacity. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement planning. The G5200AS operates in the G5000 series and is packaged in the 1812 (4532 Metric) form factor for SMD applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the G5200AS are identified based on the following allowable parameters for gas discharge tube substitution:

• Mounting type: Surface Mount (required match)
• Fail short characteristic: No (required match)
• RoHS and REACH compliance status (required match)
• Manufacturer: Bourns Inc. (preferred continuity)
• Voltage and current ratings: Allowable variation within application tolerance
• Number of poles: Allowable variation based on circuit requirements
• Package form factor: Allowable variation for SMD compatibility

The two substitute parts listed below meet these criteria while offering different electrical ratings and pole configurations suitable for alternative circuit implementations.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by Bourns Inc. and maintain active product status, ensuring long-term availability and supply chain stability compared to the obsolete G5200AS.

The 2031-42T-SM-RPLF maintains the 2-pole configuration of the original part and is packaged in the 2-SMD Cylinder Square End form factor. This part operates at 360 V spark over voltage with 1000 A impulse discharge current capacity. Selection of this substitute is appropriate for applications where the 2-pole topology is required and where the lower current rating (1 kA versus 2 kA) is acceptable.

The 2030-42T-SM-RPLF offers a 3-pole configuration with 360 V spark over voltage and 4000 A impulse discharge current capacity, packaged in the 3-SMD Cylinder Square End form factor. This substitute is suitable for applications requiring higher current handling capacity or multi-pole protection topology.

Both substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Why is the G5200AS listed as obsolete? A: The G5200AS is classified as obsolete by the manufacturer. Active substitute parts from the Bourns Mini-TRIGARD™ 2030-SM and 2031-xxT-SM series are available to fulfill equivalent protection functions.

Q: Can the 2031-42T-SM-RPLF directly replace the G5200AS? A: The 2031-42T-SM-RPLF maintains the same 2-pole configuration and surface mount technology as the G5200AS. However, the spark over voltage is 360 V (versus 400 V) and impulse discharge current is 1000 A (versus 2000 A). Substitution is valid only if the application circuit tolerates these lower ratings.

Q: What is the difference between the two substitute parts? A: The 2030-42T-SM-RPLF is a 3-pole device with 4000 A current capacity, while the 2031-42T-SM-RPLF is a 2-pole device with 1000 A current capacity. Both operate at 360 V spark over voltage. Selection depends on circuit topology requirements and current handling needs.

Q: Are the substitute parts available in the same package as the G5200AS? A: No. The G5200AS uses a 1812 (4532 Metric) package, while the substitutes use different SMD cylinder square end packages (3-SMD and 2-SMD respectively). PCB layout modifications may be required.

Q: Do the substitute parts maintain the same compliance certifications? A: Yes. Both substitute parts are ROHS3 compliant, REACH unaffected, and have MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the G5200AS.

Q: What is the tolerance specification for the substitute parts? A: The substitute parts do not specify a tolerance value in the available data. The original G5200AS specifies ±20% tolerance.
