Phoenix Contact 2908726 DT-LAN-CAT.6A Transient Voltage Suppressor

Part Overview

The Phoenix Contact 2908726 is a Transient Voltage Suppressor (TVS) module designed for circuit protection in Category 6A LAN applications. Designated as DT-LAN-CAT.6A, this single-pole device provides transient overvoltage protection with a continuous operating voltage of 3.3VDC and a protection level of 900V at the 2416 test condition.

This component is classified as obsolete. Locating equivalent or substitute parts is necessary to maintain system availability and ensure continuity in circuit protection applications where this module was originally specified.

Engineering Selection Recommendations

The Phoenix Contact 2908726 is an obsolete component. When selecting a replacement:

• Verify that the substitute maintains the 3.3VDC MCOV rating to ensure proper circuit protection without nuisance triggering
• Confirm discharge current specifications (100 A nominal, 10 kA maximum) match the transient energy levels in the protected circuit
• Ensure the 900 V protection level (VP at 2416) is maintained for the intended LAN application
• Verify DIN Rail mounting compatibility with existing installation infrastructure
• Confirm RoHS Compliance status for regulatory and procurement requirements
• Validate operating temperature range compatibility with the deployment environment

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the Phoenix Contact 2908726?

A: A valid substitute must match the electrical specifications (3.3VDC MCOV, 100 A nominal discharge current, 10 kA maximum discharge current, 900 V protection level) and maintain the single-pole, DIN Rail-mounted module form factor. The operating temperature range and RoHS compliance status should also align with the original specification.

Q: Can I use a substitute with a different MCOV rating?

A: No. The MCOV rating of 3.3VDC is critical to the circuit protection function. A higher rating will not provide adequate protection; a lower rating may cause nuisance triggering. The MCOV must match exactly.

Q: Are there any packaging considerations for substitutes?

A: Yes. The original component is a module-only form factor with DIN Rail mounting. Any substitute must maintain this mounting type and form factor to ensure compatibility with the existing installation.

Q: What is the significance of the 8/20µS discharge current specification?

A: The 8/20µS waveform is the standard test pulse for transient suppression devices. The nominal 100 A and maximum 10 kA values at this waveform define the device's ability to handle transient overvoltage events. Substitutes must meet or exceed these specifications.

Q: Does RoHS Compliance status affect substitution?

A: Yes. The original component is RoHS Compliant. Substitutes should maintain this compliance status to meet regulatory requirements and ensure consistency with procurement standards.
