Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2035-30-SM-RPLF are qualified based on the following critical parameters:

• Voltage - DC Spark Over (Nominal): 300 V
• Impulse Discharge Current (8/20µs): 5000A (5kA)
• Number of Poles: 2
• Mounting Type: Surface Mount
• Fail Short characteristic: No
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

All identified substitutes meet these core electrical and mechanical requirements, ensuring functional equivalence in overvoltage protection applications. Tolerance variations and minor package geometry differences do not affect substitutability within the same circuit design.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2035-30-SM-RPLF, B88069X9871T702, and SH300—are active production components with ROHS3 compliance and MSL 1 ratings. Selection among these equivalents may be based on:

• Tolerance requirements: The 2035-30-SM-RPLF offers ±15% tolerance, while the B88069X9871T702 provides ±20% tolerance.
• Manufacturer availability and lead time considerations.
• Existing supply chain relationships and inventory levels.
• Package geometry compatibility with PCB layout constraints, noting minor variations in case dimensions between manufacturers.

All parts are suitable for direct substitution in 300V, 5kA 2-pole overvoltage protection circuits.

Frequently Asked Questions (FAQ)

Q: Can the B88069X9871T702 replace the 2035-30-SM-RPLF in existing designs?

A: Yes. Both parts share identical electrical specifications (300V spark-over, 5kA discharge current, 2-pole configuration) and surface mount packaging. The ±20% tolerance of the B88069X9871T702 versus ±15% for the 2035-30-SM-RPLF represents a minor difference that does not affect functional equivalence in standard overvoltage protection applications.

Q: Are there mechanical compatibility concerns when substituting the SH300?

A: The SH300 uses a 2-SMD Square End Block package versus the Cylinder Square End packages of the other two parts. While both are surface mount 2-pole configurations, PCB footprint and land pattern compatibility must be verified for the specific application. Consult manufacturer datasheets for precise dimensional specifications.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) ratings, and are classified under ECCN EAR99 with HTSUS code 8536.30.8000.

Q: What is the primary criterion for substitution among these parts?

A: The primary criterion is matching the 300V DC spark-over voltage and 5000A impulse discharge current rating. All three parts meet these core specifications, making them functionally equivalent for overvoltage protection in 2-pole surface mount applications.
