Bourns 2015-50-A-RPLF Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2015-50-A-RPLF is a 2-pole surface mount gas discharge tube (GDT) rated for 500V DC spark-over voltage with 5kA impulse discharge current capability. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 2015 series provides overvoltage protection in telecommunications and industrial applications where transient suppression is required.

Key Parameters

Substitute Part Grouping Explanation

The Bourns 2017-50-A-RPLF qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Voltage - DC Spark Over (Nominal): 500 V (identical)
• Tolerance: ±20% (identical)
• Number of Poles: 2 (identical)
• Fail Short: No (identical)
• Mounting Type: Surface Mount (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)

Differing Parameter:

• Impulse Discharge Current (8/20µs): 2017-50-A-RPLF rated at 10kA versus 2015-50-A-RPLF rated at 5kA

The 2017-50-A-RPLF provides higher impulse discharge current capability while maintaining identical voltage rating and electrical characteristics. This represents a performance upgrade path for the obsolete 2015 series.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 2017-50-A-RPLF is the designated substitute for the obsolete 2015-50-A-RPLF. Both components maintain identical voltage ratings, pole configuration, and fail-safe characteristics. The 2017 series is currently in active production status, ensuring long-term availability and supply chain continuity.

The 2017-50-A-RPLF provides enhanced impulse discharge current rating (10kA versus 5kA), which represents improved transient suppression capability without compromising compatibility with existing circuit designs. Both parts carry identical RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2017-50-A-RPLF directly replace the 2015-50-A-RPLF in existing designs?

A: Yes. Both components share identical voltage ratings (500V), pole configuration (2-pole), mounting type (surface mount), and fail-safe characteristics (no fail short). The 2017 series provides higher impulse discharge current capability, which is functionally compatible with applications designed for the 2015 series.

Q: What is the primary difference between these two parts?

A: The impulse discharge current rating differs: the 2015-50-A-RPLF is rated at 5kA, while the 2017-50-A-RPLF is rated at 10kA. Both maintain the same 500V DC spark-over voltage and ±20% tolerance.

Q: Are there package or footprint differences?

A: The 2015-50-A-RPLF uses a 2-SMD package, while the 2017-50-A-RPLF uses a Microde Button package. Physical dimensions and PCB footprints may differ; verify mechanical compatibility with your specific application layout.

Q: Do both parts meet current compliance standards?

A: Yes. Both the 2015-50-A-RPLF and 2017-50-A-RPLF are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry MSL 1 (unlimited moisture sensitivity level).

Q: Why is the 2015 series marked as obsolete?

A: The 2015 series has been superseded by the active 2017 FLAT® series. Bourns continues to support the 2017 series for new designs and ongoing production requirements.
