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

Part Overview

The Bourns 2015-09-SMH-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 production continuity. The 2015 series has been superseded by newer product lines offering enhanced performance characteristics while maintaining core electrical compatibility parameters.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

Substitution of the 2015-09-SMH-RPLF is determined by the following critical electrical and mechanical parameters:

• Voltage Rating Match: DC spark-over voltage must remain at 90V nominal to ensure circuit protection operates at the intended threshold
• Pole Configuration: 2-pole topology must be maintained for circuit topology compatibility
• Fail Mode: Non-fail-short characteristic must be preserved
• Surface Mount Compatibility: Mounting type must support surface mount assembly processes
• Regulatory Compliance: RoHS3 and REACH compliance status must be maintained

The Bourns 2017-09-SMH-RPLF qualifies as a direct substitute based on matching voltage rating, pole count, fail mode, and regulatory compliance. The 2017 series represents the active product line replacement for the obsolete 2015 series.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 2017-09-SMH-RPLF is the designated active product replacement for the obsolete 2015-09-SMH-RPLF. Both components maintain identical DC spark-over voltage (90V) and pole configuration (2-pole), ensuring functional equivalence in circuit protection applications.

The 2017 series offers increased impulse discharge current capability (10kA versus 5kA), providing enhanced transient suppression performance. This higher current rating is backward-compatible with applications designed for the 2015 series, as the substitute component can handle all transient events the original part was specified to manage.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production environments. The MSL rating of 1 (Unlimited) for both components indicates no moisture sensitivity constraints during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 2017-09-SMH-RPLF directly replace the 2015-09-SMH-RPLF in existing designs?

A: Yes. Both components share the same 90V DC spark-over voltage and 2-pole configuration. The 2017 series provides higher impulse discharge current (10kA), which is a performance enhancement suitable for applications originally designed for the 5kA-rated 2015 series.

Q: What is the difference in package configuration between these parts?

A: The 2015-09-SMH-RPLF uses a 2-SMD package, while the 2017-09-SMH-RPLF uses a Disc 8.00mm Tabbed SMD package. Both are surface mount configurations; however, PCB layout and footprint design must accommodate the specific package geometry of the selected part.

Q: Are there any compliance differences between the two parts?

A: No. Both the 2015-09-SMH-RPLF and 2017-09-SMH-RPLF maintain identical RoHS3 compliance and REACH unaffected status. Moisture sensitivity levels are also equivalent at MSL 1 (Unlimited).

Q: Why is the 2015 series listed as obsolete?

A: The 2015 series has been discontinued by Bourns Inc. in favor of the active 2017 product line. The 2017 series provides improved performance characteristics while maintaining backward compatibility with existing circuit designs.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: DC spark-over voltage (90V), number of poles (2), fail mode (non-fail-short), and surface mount mounting type. The impulse discharge current rating may be equal or higher in the substitute part.
