Bourns 2037-60-CLF Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The Bourns 2037-60-CLF is a Gas Discharge Tube (GDT) rated for 600V DC spark-over voltage with 5000A (5kA) impulse discharge current capacity in a 2-pole through-hole configuration. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and component procurement.

The 2037-60-CLF serves as a surge protection device in applications requiring reliable overvoltage suppression. Due to its obsolete status, the active equivalent 2037-60-BLF provides continuity for new designs and replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2037-60-CLF is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 600 V
• Impulse Discharge Current (8/20µs): 5000A (5kA)
• Tolerance: ±15%
• Number of Poles: 2
• Fail Short characteristic: No
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder

The 2037-60-BLF meets all substitution criteria. The primary distinction between the main part and its substitute is packaging format (tape and reel versus bulk) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The 2037-60-BLF is the direct functional equivalent to the 2037-60-CLF. Both components share identical electrical and mechanical specifications across all critical parameters. The 2037-60-BLF carries active product status, ensuring ongoing manufacturer support and availability.

Selection of the 2037-60-BLF is appropriate for:

• Replacement of obsolete 2037-60-CLF units in existing designs
• New designs requiring 600V, 5kA surge protection in 2-pole through-hole configuration
• Applications requiring ROHS3 compliance and REACH unaffected status

Packaging differences (tape and reel versus bulk) do not affect electrical or mechanical performance and should be evaluated based on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2037-60-BLF directly replace the 2037-60-CLF in existing circuit designs?

A: Yes. The 2037-60-BLF is electrically and mechanically equivalent to the 2037-60-CLF across all functional parameters, including voltage rating, discharge current capacity, pole configuration, and mounting type. No circuit modifications are required.

Q: What is the difference between the 2037-60-CLF and 2037-60-BLF?

A: The components are functionally identical. The primary differences are product status (obsolete versus active) and packaging format (tape and reel versus bulk). These differences do not affect electrical performance or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2037-60-CLF and 2037-60-BLF are ROHS3 compliant and REACH unaffected.

Q: What does the ±15% tolerance specification mean?

A: The ±15% tolerance applies to the DC spark-over voltage rating of 600V, indicating acceptable variation in the spark-over threshold across the component population.

Q: Can these components be used in applications requiring different voltage ratings?

A: No. These components are rated specifically for 600V DC spark-over voltage. Applications with different voltage requirements require components with corresponding voltage ratings.

Q: Is the through-hole mounting type compatible with automated assembly?

A: Through-hole components are compatible with wave soldering and selective soldering processes. Assembly method compatibility should be evaluated based on specific production equipment and process requirements.
