Substitute Part Grouping Explanation

The 2036-47-B2LF qualifies as a direct substitute for the 2036-47-C2LF based on identical electrical and mechanical specifications. Substitution is valid when the following parameters match exactly:

• Voltage - DC Spark Over (Nominal): 470 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Tolerance: ±20%
• Number of Poles: 3
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)
• Fail Short: No

The primary distinction between these parts is packaging format and product status. The 2036-47-B2LF is supplied in Tray packaging and maintains Active product status, whereas the 2036-47-C2LF is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The 2036-47-B2LF is the direct functional equivalent for the obsolete 2036-47-C2LF. Both components meet ROHS3 compliance and REACH requirements. Selection of the 2036-47-B2LF is supported by its Active product status, ensuring continued availability and manufacturer support. The electrical performance, mechanical form factor, and environmental compliance are identical across both parts, making the 2036-47-B2LF suitable for direct replacement in existing designs or new applications requiring 470V, 10kA 3-pole gas discharge tube protection.

Frequently Asked Questions (FAQ)

Q: Can the 2036-47-B2LF replace the 2036-47-C2LF in existing designs?

A: Yes. The 2036-47-B2LF provides identical electrical ratings (470V spark-over, 10kA impulse current), mechanical configuration (3-pole through-hole, axial cylinder with radial bend), and environmental compliance. Direct substitution is valid.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format and product lifecycle status. The 2036-47-C2LF is obsolete, while the 2036-47-B2LF is Active. The 2036-47-B2LF is supplied in Tray packaging. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with the packaging difference?

A: No. Packaging format (Tray vs. unspecified) does not affect component performance or board-level compatibility. The physical form factor and lead configuration remain unchanged.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 2036-47-C2LF and 2036-47-B2LF are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Why should I select the 2036-47-B2LF over the obsolete 2036-47-C2LF?

A: The 2036-47-B2LF maintains Active product status, ensuring ongoing availability, manufacturer support, and supply chain reliability. Obsolete components present procurement risk and may have limited stock.
