Bourns 2015-35-SMH-RPLF Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The Bourns 2015-35-SMH-RPLF is a 2-pole surface mount gas discharge tube (GDT) rated for 350V 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 The 2015 series has been superseded by newer product lines offering enhanced performance characteristics while maintaining core electrical compatibility parameters.

Key Parameters

Substitute Part Grouping Explanation

The Bourns 2017-35-SMH-RPLF qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Voltage - DC Spark Over: 350V (identical)
• Tolerance: ±20% (identical)
• Number of Poles: 2 (identical)
• Fail Short: No (identical)
• Surface Mount technology (compatible)
• RoHS3 Compliance (identical)
• MSL 1 rating (identical)
• REACH Unaffected status (identical)

Differing Parameters:

• Impulse Discharge Current: 2017 series rated at 10kA versus 2015 series at 5kA (higher capacity in substitute)
• Mounting orientation: 2017 series specified as horizontal orientation
• Package designation: 2017 uses Disc 8.00mm Tabbed SMD versus 2-SMD for 2015
• Packaging format: 2017 available in Tape & Reel (TR) versus standard packaging for 2015

The 2017-35-SMH-RPLF provides enhanced discharge current handling (10kA) while maintaining the same spark-over voltage threshold, making it suitable for applications requiring equal or greater surge protection capability.

Parameter Comparison

Engineering Selection Recommendations

The 2017-35-SMH-RPLF is the designated substitute for the obsolete 2015-35-SMH-RPLF based on product lifecycle status and regulatory compliance alignment. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental standards.

The 2017 series offers active product status with current manufacturing support, addressing the obsolescence constraint of the 2015 series. The increased impulse discharge current rating (10kA versus 5kA) provides enhanced surge protection margin without compromising the critical 350V spark-over voltage specification.

Mechanical compatibility requires evaluation of the horizontal mounting orientation and disc package geometry of the 2017 series against the original 2-SMD package footprint. PCB layout and component placement must accommodate the Disc 8.00mm Tabbed SMD package configuration.

Frequently Asked Questions (FAQ)

Q: Can the 2017-35-SMH-RPLF directly replace the 2015-35-SMH-RPLF in existing designs?

A: Electrical substitution is valid based on matching 350V spark-over voltage and 2-pole configuration. Physical substitution requires PCB layout verification due to package geometry differences (Disc 8.00mm Tabbed SMD versus 2-SMD) and horizontal mounting orientation of the 2017 series.

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

A: The 2017-35-SMH-RPLF provides double the impulse discharge current capacity (10kA versus 5kA). This represents enhanced surge protection capability and does not compromise compatibility with circuits designed for the lower 5kA rating, as the spark-over voltage threshold remains identical at 350V.

Q: Are there compliance or regulatory differences between these parts?

A: Both components maintain identical regulatory status: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited moisture sensitivity). No compliance barriers exist for substitution from a regulatory perspective.

Q: What packaging format differences should be considered?

A: The 2015-35-SMH-RPLF uses standard 2-SMD packaging, while the 2017-35-SMH-RPLF is available in Tape & Reel (TR) format. The TR packaging is standard for high-volume automated assembly processes and does not affect component electrical performance.

Q: Why is the 2015 series classified as obsolete?

A: Product obsolescence reflects manufacturer discontinuation of the 2015 series line. The 2017 series represents the current active product offering from Bourns Inc. for this voltage and pole configuration category.
