Substitute Part Grouping Explanation

Substitution for the 2036-42-C2F is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - DC Spark Over (Nominal): 420 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Tolerance: ±20%
• Number of Poles: 3
• Fail Short: Yes
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)
• Base Product Number: 2036

The substitute part 2036-42-B2F maintains identical electrical performance specifications and mechanical form factor, with the primary distinction being product status (Active vs. Obsolete) and packaging configuration (Tray vs. original packaging).

Parameter Comparison

Engineering Selection Recommendations

The 2036-42-B2F serves as a direct functional equivalent to the obsolete 2036-42-C2F. Both parts share identical electrical ratings (420V DC spark-over, 10kA impulse discharge current) and mechanical specifications (3-pole through-hole, axial cylinder package). The substitute part maintains active product status, ensuring continued availability and supply chain reliability.

Both parts carry identical compliance designations: RoHS non-compliant and REACH Affected. Selection between these parts should be based on procurement availability and packaging requirements, as the electrical and mechanical performance characteristics are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 2036-42-B2F directly replace the 2036-42-C2F in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent, with identical spark-over voltage (420V), impulse discharge current (10kA), pole configuration (3-pole), and through-hole mounting specifications.

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

A: The main differences are product status (2036-42-C2F is Obsolete; 2036-42-B2F is Active) and packaging configuration (Tray vs. original packaging). Electrical and mechanical performance are identical.

Q: Are there any compliance differences between the substitute and the original part?

A: No. Both parts share identical RoHS and REACH compliance status. Both are RoHS non-compliant and REACH Affected.

Q: Does packaging type affect electrical performance?

A: No. Packaging type (Tray vs. original) does not affect electrical performance or mechanical fit. Selection should be based on procurement and handling requirements.

Q: Is the 2036-42-B2F suitable for new designs?

A: Yes. The active product status of 2036-42-B2F makes it suitable for new designs requiring 420V, 10kA, 3-pole gas discharge tube protection in through-hole configuration.
