2035-15-SM-RPLF Equivalent & Substitute Parts

Part Overview

The 2035-15-SM-RPLF is a Gas Discharge Tube (GDT) manufactured by Bourns Inc., designed for overvoltage protection in surface mount applications. This 2-pole device operates at 150 V DC spark over voltage with 5000A (5kA) impulse discharge current capacity. The component is actively produced and RoHS3 compliant, making it suitable for modern electronic assemblies requiring transient voltage suppression.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2035-15-SM-RPLF is determined by the following critical parameters:

• Voltage - DC Spark Over: Substitute parts must operate within the allowed tolerance range for the application voltage class
• Impulse Discharge Current: Substitute parts must match or exceed the 5000A (5kA) rating
• Number of Poles: Substitute parts must maintain 2-pole configuration for circuit compatibility
• Mounting Type: Substitute parts must be Surface Mount to ensure PCB assembly compatibility
• Package / Case: Substitute parts must use equivalent 2-SMD form factors
• Fail Mode: Substitute parts must not fail short to maintain circuit safety
• RoHS Status: Substitute parts must meet ROHS3 compliance for regulatory alignment
• MSL Rating: Substitute parts must maintain MSL 1 for storage and handling consistency

The SH145 from Littelfuse Inc. qualifies as a substitute based on matching electrical performance and mechanical compatibility within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 2035-15-SM-RPLF and SH145 are actively produced components with ROHS3 compliance and equivalent electrical specifications. Selection between these parts should be based on:

• Voltage Margin: The 2035-15-SM-RPLF operates at 150 V nominal spark over, while the SH145 operates at 145 V nominal. Applications requiring higher voltage margin should specify the 2035-15-SM-RPLF.
• Supply Chain Availability: Current inventory levels differ between manufacturers. The 2035-15-SM-RPLF has 6211 pcs in stock versus 866 pcs for the SH145.
• Regulatory Compliance: Both parts meet ROHS3 and REACH requirements, with identical MSL ratings and fail-safe characteristics.
• Package Compatibility: Both use 2-SMD surface mount packages with equivalent mechanical footprints suitable for automated assembly.

Frequently Asked Questions (FAQ)

Q: Can the SH145 be used as a direct replacement for the 2035-15-SM-RPLF?

A: Yes, the SH145 qualifies as a substitute based on matching impulse discharge current (5kA), pole configuration (2-pole), mounting type (surface mount), package form factor (2-SMD), fail mode (no fail short), and compliance ratings (ROHS3, MSL 1). The 5 V difference in nominal spark over voltage (145 V vs 150 V) remains within acceptable application tolerance for GDT substitution.

Q: What is the significance of the 150 V versus 145 V spark over voltage difference?

A: The spark over voltage determines the threshold at which the GDT transitions to conduction. The 2035-15-SM-RPLF at 150 V provides a 5 V higher margin before activation compared to the SH145 at 145 V. Applications with strict voltage protection windows should evaluate this difference against circuit requirements.

Q: Are the package dimensions identical between these parts?

A: Both parts use 2-SMD surface mount packages with square end configurations. The 2035-15-SM-RPLF specifies "Cylinder Square End" while the SH145 specifies "Square End Block." These represent equivalent mechanical form factors suitable for the same PCB footprints and automated assembly processes.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes, both the 2035-15-SM-RPLF and SH145 carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions for storage, handling, or assembly.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8536.30.8000) classifications for regulatory and trade purposes.
