Equivalent & Substitute Parts for Bourns 2015-42-A-RPLF Gas Discharge Tube

Part Overview

The Bourns 2015-42-A-RPLF is a 2-pole surface mount gas discharge tube (GDT) rated for 420V DC spark-over voltage with 5kA impulse discharge current capacity. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement planning. The 2015 series GDT provides overvoltage protection in two-pole configurations for industrial and telecommunications applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2015-42-A-RPLF is determined by the following critical parameters:

• Voltage Rating (DC Spark Over): Must match 420V nominal specification
• Number of Poles: Must remain 2-pole configuration
• Mounting Type: Must be surface mount to maintain PCB compatibility
• Fail Short Characteristic: Must be non-fail-short to preserve circuit protection behavior
• Tolerance: ±20% tolerance maintained across substitutes
• Compliance: RoHS3 and REACH status must be maintained

The Bourns 2017-42-A-RPLF qualifies as a direct substitute based on matching voltage rating, pole count, mounting type, fail-short characteristic, and compliance certifications. The primary difference is the increased impulse discharge current rating (10kA versus 5kA), which represents an enhancement in surge handling capacity while maintaining all other critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The 2017-42-A-RPLF is a qualified substitute for the obsolete 2015-42-A-RPLF. Both components maintain identical voltage ratings, pole configuration, and compliance certifications. The 2017 series offers active product status with current manufacturing support, addressing the obsolescence of the original 2015 series part.

The increased impulse discharge current rating of the 2017-42-A-RPLF (10kA versus 5kA) provides enhanced surge protection capability. This higher current rating is compatible with applications originally designed for the 5kA-rated 2015 series, as the substitute maintains the same spark-over voltage and fail-short characteristic.

Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Can the 2017-42-A-RPLF directly replace the 2015-42-A-RPLF on existing PCBs?

A: Yes. Both components are 2-pole surface mount GDTs with identical 420V spark-over ratings and matching fail-short characteristics. The mounting footprint compatibility is maintained within the surface mount package category.

Q: What is the significance of the increased 10kA discharge current in the 2017 series?

A: The 2017-42-A-RPLF provides double the impulse discharge current capacity (10kA versus 5kA). This enhancement increases the surge handling capability while maintaining the same voltage protection threshold, making it suitable for applications requiring higher transient energy dissipation.

Q: Are there compliance differences between the two parts?

A: No. Both the 2015-42-A-RPLF and 2017-42-A-RPLF maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity levels are identical at MSL 1 (Unlimited).

Q: Why is the 2015 series marked as obsolete?

A: The 2015 series has reached end-of-life status. The 2017 series represents the active product line continuation from Bourns Inc., offering equivalent protection characteristics with current manufacturing availability.

Q: Are there package differences between these parts?

A: The main part specifies 2-SMD package, while the substitute lists Microde Button package designation. Both are surface mount configurations suitable for SMD assembly processes.
