Key Parameters

Substitute Part Grouping Explanation

The Bourns 2017-23-SMH-RPLF qualifies as a direct substitute based on the following critical parameters:

• Voltage Rating Match: Both parts maintain 230V DC spark-over voltage, ensuring compatibility in the same circuit protection application
• Pole Configuration Match: Both are 2-pole devices, maintaining identical circuit topology requirements
• Fail Short Characteristic Match: Both parts exhibit non-fail-short behavior, preserving circuit safety characteristics
• Compliance Alignment: Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements
• Moisture Sensitivity Match: Both parts have MSL 1 (Unlimited), requiring identical handling and storage conditions

The primary difference is the enhanced impulse discharge current capacity (10kA versus 5kA), which represents an upgrade path suitable for applications requiring higher transient energy dissipation while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 2017-23-SMH-RPLF is the active equivalent for the obsolete 2015-23-SMH-RPLF. Both parts maintain identical voltage ratings, pole configurations, and regulatory compliance status. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The 2017-23-SMH-RPLF provides increased impulse discharge current capacity (10kA versus 5kA), which enhances transient protection margins in the same 230V circuit protection application. The physical package differs (Disc 8.00mm Tabbed SMD versus 2-SMD), requiring PCB layout verification during design transition.

Frequently Asked Questions (FAQ)

Q: Can the 2017-23-SMH-RPLF directly replace the 2015-23-SMH-RPLF in existing designs?

A: The 2017-23-SMH-RPLF maintains the same 230V spark-over voltage and 2-pole configuration. However, the physical package differs (Disc 8.00mm Tabbed SMD versus 2-SMD), requiring PCB footprint verification before implementation.

Q: What is the significance of the higher 10kA discharge current in the substitute part?

A: The 2017-23-SMH-RPLF provides double the impulse discharge current capacity. This represents an upgrade that maintains compatibility with the original 230V voltage specification while offering enhanced transient energy dissipation capability.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the 2015-23-SMH-RPLF and 2017-23-SMH-RPLF are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the difference between the mounting types listed?

A: The main part uses standard Surface Mount (2-SMD package), while the substitute uses Surface Mount Horizontal configuration with a Disc 8.00mm Tabbed SMD package. Both are surface mount technologies; the horizontal orientation and physical dimensions differ.

Q: Does the substitute part have the same fail-short characteristic?

A: Yes. Both parts exhibit non-fail-short behavior, preserving identical circuit safety characteristics in transient protection applications.
