Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TBU-CX065-VTC-WH are selected based on the following critical parameters that must remain constant:

• Voltage - Clamping: 650V (all substitutes maintain this specification)
• Voltage - Working: 300V (all substitutes maintain this specification)
• Technology: Internal Switch (all substitutes use identical technology)
• Series: TBU® (all substitutes belong to the same product family)
• Mounting Type: Surface Mount (all substitutes are surface mount components)
• RoHS Status: ROHS3 Compliant (all substitutes meet compliance requirements)

The primary difference between the main part and substitute parts is the Number of Circuits and current rating specifications. The TBU-CX065-VTC-WH features 2 circuits, while all listed substitutes feature 1 circuit with varying current ratings (50mA, 100mA, 200mA, 300mA, 500mA). These substitutes are functionally equivalent when circuit count requirements align with application needs.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain identical electrical specifications (650V clamping, 300V working voltage, internal switch technology) and comply with ROHS3 requirements. The primary selection criterion is product status: all substitute parts carry Active status, whereas the TBU-CX065-VTC-WH is Obsolete. This makes any of the listed substitutes suitable for new designs and production continuity.

Selection among the substitute options should be based on circuit count requirements and current rating specifications appropriate to the application. The TBU-CA065 series substitutes are available in current ratings of 50mA, 100mA, 200mA, 300mA, and 500mA, each with single-circuit configuration. All substitutes are REACH Unaffected and carry EAR99 ECCN classification, matching the compliance profile of the main part.

Frequently Asked Questions (FAQ)

Q: Can TBU-CA065 series parts directly replace the TBU-CX065-VTC-WH?

A: Yes, provided the application requires single-circuit protection. The TBU-CX065-VTC-WH features 2 circuits, while TBU-CA065 substitutes feature 1 circuit. Electrical specifications (650V clamping, 300V working voltage, internal switch technology) are identical across all parts.

Q: What is the difference between the various TBU-CA065 current ratings?

A: The TBU-CA065 series is available in five current rating options: 50mA, 100mA, 200mA, 300mA, and 500mA. Selection depends on the maximum current the surge suppressor must handle in the application circuit.

Q: Are there package size differences between the main part and substitutes?

A: Yes. The TBU-CX065-VTC-WH uses SMD 4.00mm x 8.25mm packaging, while all TBU-CA065 substitutes use SMD 6.50mm x 4.00mm packaging. PCB layout modifications may be required during component substitution.

Q: Do all parts meet the same compliance standards?

A: All listed parts are ROHS3 Compliant, REACH Unaffected, and carry EAR99 ECCN classification. Moisture Sensitivity Level differs: the main part is MSL 3 (168 Hours), while substitutes are MSL 1 (Unlimited), providing superior moisture resistance in the substitute options.

Q: What packaging formats are available for the substitute parts?

A: TBU-CA065-050-WH and TBU-CA065-500-WH are supplied in Tape & Reel (TR) format. TBU-CA065-100-WH, TBU-CA065-200-WH, and TBU-CA065-300-WH are available in Cut Tape (CT) & Digi-Reel® format.
