Substitute Part Grouping Explanation

Substitution eligibility for the 2036-42-C2 is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - DC Spark Over (Nominal): 420 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 characteristic: No

The identified substitute part maintains identical electrical performance specifications and mechanical form factor, differing only in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The 2036-42-B2 is the direct equivalent substitute for the obsolete 2036-42-C2. Both parts are manufactured by Bourns Inc. within the Mini-TRIGARD™ 2036 series and provide identical electrical and mechanical specifications. The 2036-42-B2 maintains active product status, ensuring continued availability and supply chain support.

Both parts carry identical regulatory classifications: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8536.30.8000. The only operational difference is packaging configuration: the main part is supplied in bulk, while the substitute is supplied in trays. This distinction does not affect component performance or circuit-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 2036-42-B2 be used as a direct replacement for the 2036-42-C2?

A: Yes. The 2036-42-B2 is electrically and mechanically identical to the 2036-42-C2. Both parts share the same 420V DC spark-over voltage, 10kA impulse discharge current rating, 3-pole configuration, and through-hole mounting specifications.

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

A: The primary differences are product status and packaging. The 2036-42-C2 is obsolete and supplied in bulk packaging, while the 2036-42-B2 is active and supplied in tray packaging. Electrical and mechanical performance are identical.

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

A: No. Both parts carry identical regulatory status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8536.30.8000.

Q: Does the packaging difference (bulk vs. tray) affect circuit performance?

A: No. Packaging configuration does not affect electrical performance or mechanical compatibility. The difference is limited to handling, storage, and logistics considerations.

Q: Why is the 2036-42-C2 listed as obsolete?

A: The 2036-42-C2 has been superseded by the 2036-42-B2 within Bourns Inc.'s product portfolio. The 2036-42-B2 is the active equivalent and is the recommended part for new designs and procurement.
