Bourns 2015-15-A-RPLF Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2015-15-A-RPLF is a 2-pole surface mount gas discharge tube (GDT) rated for 150V 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

Substitution eligibility for the 2015-15-A-RPLF is determined by the following critical parameters:

• Voltage - DC Spark Over (Nominal): Must match 150V
• Number of Poles: Must be 2-pole configuration
• Mounting Type: Must be Surface Mount
• Fail Short Characteristic: Must be No
• Tolerance: ±20%

The Bourns 2017-15-A-RPLF qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary difference is the impulse discharge current rating, which is higher (10kA vs. 5kA), making this part suitable for applications requiring equal or greater transient protection capability within the same voltage and pole configuration.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 2017-15-A-RPLF is the appropriate substitute for the obsolete 2015-15-A-RPLF. Both parts maintain identical voltage and pole specifications, ensuring electrical compatibility in existing circuit designs. The 2017 series offers active product status with continued manufacturer support and availability.

The higher impulse discharge current rating (10kA vs. 5kA) of the 2017-15-A-RPLF provides enhanced transient suppression capability. This upgrade does not compromise circuit performance and is suitable for direct replacement in applications originally designed for the 2015 series.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and telecommunications applications. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the 2017-15-A-RPLF directly replace the 2015-15-A-RPLF in existing designs?

A: Yes. Both parts share identical DC spark-over voltage (150V), pole configuration (2-pole), mounting type (surface mount), and fail-short characteristic (No). The 2017 series is a direct electrical and mechanical substitute.

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

A: The 2017-15-A-RPLF provides greater transient suppression capability (10kA vs. 5kA). This higher rating does not affect compatibility with existing circuit designs and offers improved protection margins for overvoltage events.

Q: Are there package compatibility concerns between the 2015 and 2017 series?

A: Both parts are surface mount devices. The 2015 uses a 2-SMD package, while the 2017 uses a Microde Button package. PCB layout and footprint compatibility must be verified during design transition, as package dimensions may differ despite identical electrical specifications.

Q: Do regulatory certifications differ between these parts?

A: No. Both the 2015-15-A-RPLF and 2017-15-A-RPLF maintain ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). Regulatory requirements are satisfied by either part.

Q: Why is the 2015 series marked as obsolete?

A: The 2015 series has reached end-of-life status. The 2017 series provides equivalent functionality with active product status and ongoing manufacturer support, making it the recommended choice for new designs and component replenishment.
