Bourns 2015-09-A-RPLF Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2015-09-A-RPLF is a 2-pole surface mount gas discharge tube (GDT) rated for 90V DC spark-over voltage with 5kA impulse discharge current capability. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement planning. The 2015 series represents an earlier generation product line, and active alternatives are available to maintain design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2015-09-A-RPLF is determined by the following critical parameters:

• Voltage Rating Match: DC spark-over voltage must remain at 90V nominal to maintain circuit protection thresholds
• Pole Configuration: 2-pole topology is required for the intended application
• Mounting Technology: Surface mount capability is mandatory for PCB integration
• Fail Mode: Non-fail-short characteristic must be preserved
• Compliance Standards: RoHS3 compliance and REACH unaffected status ensure regulatory alignment

The Bourns 2017-09-A-RPLF qualifies as a direct substitute based on matching all critical parameters. While the 2017 series offers enhanced impulse discharge current (10kA versus 5kA), this represents a performance upgrade rather than a limitation, as the higher current rating maintains backward compatibility with the original 5kA specification.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 2017-09-A-RPLF is the appropriate substitute for the obsolete 2015-09-A-RPLF. Both components maintain identical voltage ratings, pole configuration, and fail-mode characteristics. The 2017 series is currently in active production status, ensuring long-term availability and supply chain stability. Both parts carry ROHS3 compliance and REACH unaffected designation, meeting current regulatory requirements. The increased impulse discharge current rating of the 2017 series (10kA versus 5kA) provides enhanced transient protection capability without introducing compatibility issues in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 2017-09-A-RPLF be used as a direct replacement for the 2015-09-A-RPLF?

A: Yes. Both components share identical voltage ratings (90V), pole configuration (2-pole), mounting technology (surface mount), and fail-mode characteristics (non-fail-short). The 2017 series provides equivalent or superior performance across all specified parameters.

Q: What is the significance of the higher impulse discharge current in the 2017 series?

A: The 2017-09-A-RPLF is rated for 10kA impulse discharge current compared to the 2015 series 5kA rating. This represents a performance enhancement that maintains full backward compatibility. Circuits designed for 5kA protection will operate correctly with the higher-rated component.

Q: Are there package or footprint differences between these parts?

A: Both components are surface mount devices. The 2015 series uses a 2-SMD package, while the 2017 series uses a Microde Button package. PCB layout verification is recommended to confirm footprint compatibility with existing designs.

Q: Why is the 2015 series listed as obsolete?

A: The 2015 series has been superseded by the 2017 series in Bourns' product portfolio. The 2017 series offers improved performance characteristics and remains in active production, making it the recommended choice for new designs and ongoing procurement.

Q: Do both parts meet current compliance standards?

A: Yes. Both the 2015-09-A-RPLF and 2017-09-A-RPLF are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
