Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2036-40-C3LF is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 400 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Number of Poles: 3
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)
• Fail Short characteristic: No

The 2036-40-B3LF meets all substitution criteria, maintaining identical electrical performance and mechanical form factor. The primary distinction is product lifecycle status: the main part is Obsolete while the substitute is Active, with secondary differences in packaging designation (Bulk versus standard).

Parameter Comparison

Engineering Selection Recommendations

The 2036-40-B3LF is the appropriate substitute for the obsolete 2036-40-C3LF. Both components are ROHS3 Compliant and REACH Unaffected, ensuring regulatory alignment. The substitute maintains Active product status, supporting long-term availability and supply chain continuity. Electrical and mechanical specifications are identical, permitting direct replacement in circuit designs without modification. The transition from Obsolete to Active status makes the 2036-40-B3LF the preferred selection for new procurement and system redesigns.

Frequently Asked Questions (FAQ)

Q: Can the 2036-40-B3LF be used as a direct replacement for the 2036-40-C3LF?

A: Yes. Both components share identical electrical ratings (400V DC spark-over, 10kA impulse discharge current), mechanical configuration (3-pole through-hole, axial cylinder package), and compliance certifications. Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 2036-40-C3LF is classified as Obsolete, indicating discontinued manufacturing and limited future availability. The 2036-40-B3LF is Active, ensuring ongoing production and supply chain support. For new designs and long-term applications, the Active substitute is recommended.

Q: Are there packaging differences between these parts?

A: Both components use identical package types (Axial Cylinder, 3 Lead with Radial Bend). The packaging designation difference (standard versus Bulk) reflects distribution format only and does not affect electrical or mechanical compatibility.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 2036-40-C3LF and 2036-40-B3LF are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in voltage rating (400V), discharge current capacity (10kA), pole count (3), mounting type (through-hole), package configuration (axial cylinder with radial bend leads), and fail-short characteristic (No). All parameters must match for direct substitution.
