Substitute Part Grouping Explanation

The 2035-20-CLF has one direct equivalent substitute: the 2035-20-BLF. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 200 V
• Impulse Discharge Current (8/20µs): 5000A (5kA)
• Tolerance: ±15%
• Number of Poles: 2
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder
• Fail Short: No

The 2035-20-BLF maintains identical electrical and mechanical specifications to the 2035-20-CLF, with the primary distinction being product status (Active vs. Obsolete) and packaging format (Bulk vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The 2035-20-BLF is the direct equivalent substitute for the obsolete 2035-20-CLF. Both components are manufactured by Bourns Inc. and share identical electrical performance characteristics, mechanical configuration, and regulatory compliance status. The 2035-20-BLF is currently in active production status, making it the appropriate selection for new designs and component replenishment. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental regulations. The substitution presents no functional or compliance trade-offs.

Frequently Asked Questions (FAQ)

Q: Can the 2035-20-BLF be used as a direct replacement for the 2035-20-CLF in existing designs?

A: Yes. The 2035-20-BLF is electrically and mechanically identical to the 2035-20-CLF. Both components feature 200V DC spark-over voltage, 5000A impulse discharge current, 2-pole configuration, and axial cylinder through-hole packaging. No circuit modifications are required.

Q: What is the difference between the 2035-20-CLF and 2035-20-BLF?

A: The primary differences are product status and packaging format. The 2035-20-CLF is obsolete, while the 2035-20-BLF is active production. The 2035-20-BLF is supplied in bulk packaging, whereas the 2035-20-CLF uses standard packaging. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 2035-20-CLF and 2035-20-BLF maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Regulatory compliance is equivalent across both part numbers.

Q: What is the impulse discharge current rating, and why is it important for substitution?

A: Both parts are rated for 5000A (5kA) impulse discharge current at 8/20µs waveform. This parameter defines the maximum transient current the GDT can safely conduct during an overvoltage event. Substitutes must match this rating to ensure equivalent protection performance.

Q: Does packaging format affect electrical performance?

A: No. The packaging format (bulk vs. standard) does not affect electrical or mechanical performance. Both the 2035-20-CLF and 2035-20-BLF deliver identical component functionality. Packaging format is a procurement and logistics consideration only.
