Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2036-42-C2LF is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 420V
• Impulse Discharge Current (8/20µs): 10kA
• Tolerance: ±20%
• Number of Poles: 3
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)
• Fail Short characteristic: No

The substitute part 2036-42-B2LF maintains identical electrical specifications and mechanical configuration, differing only in packaging format (Bulk versus standard packaging) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 2036-42-B2LF is a direct functional equivalent to the 2036-42-C2LF. Both parts are manufactured by Bourns Inc. within the Mini-TRIGARD™ 2036 series and share identical electrical performance specifications and mechanical form factors.

The primary distinction is product lifecycle status: the 2036-42-C2LF is obsolete, while the 2036-42-B2LF maintains active product status. Both parts meet ROHS3 compliance and REACH unaffected requirements, ensuring regulatory alignment for current applications.

Selection of the 2036-42-B2LF is appropriate for new designs, redesigns, or replenishment of existing applications previously using the 2036-42-C2LF, as it provides equivalent electrical protection performance with assured long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the 2036-42-B2LF be used as a direct replacement for the 2036-42-C2LF in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The 2036-42-B2LF provides the same 420V spark-over voltage, 10kA impulse discharge current, 3-pole configuration, and through-hole axial cylinder package with radial bend leads. The difference in packaging format (Bulk) does not affect circuit performance or board-level compatibility.

Q: What is the significance of the product status difference between these parts?

A: The 2036-42-C2LF is classified as obsolete, indicating it is no longer in active production. The 2036-42-B2LF maintains active status, ensuring continued manufacturing availability and supply chain reliability for future procurement needs.

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

A: No. Both the 2036-42-C2LF and 2036-42-B2LF are ROHS3 compliant and REACH unaffected. They meet identical regulatory requirements for electronic component deployment.

Q: Does the packaging format difference affect component selection?

A: Packaging format (Bulk versus standard) relates to order quantity and delivery configuration, not to electrical or mechanical performance. The component itself remains functionally identical regardless of packaging designation.
