• Number of Circuits: 2
• Technology: Internal Switch or equivalent protection mechanism
• Applications: SLIC compatibility
• Voltage - Working: Equal to or greater than 300V
• Voltage - Clamping: Equal to or greater than 500V
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts listed below meet these criteria and are suitable for direct replacement or design integration in applications previously utilizing the TBU-PL050-200-WH.

Parameter Comparison

Engineering Selection Recommendations

TBU-PL060-200-WH is the primary recommended substitute for the obsolete TBU-PL050-200-WH. This part maintains identical mechanical compatibility (SMD 6.50mm x 4.00mm package), dual-circuit configuration, and internal switch technology. The TBU-PL060-200-WH offers enhanced voltage ratings (600V clamping, 350V working) compared to the original part, providing improved performance margin in SLIC applications. The part is currently in active production status with substantial inventory availability. Both parts maintain ROHS3 compliance and MSL 1 rating.

TISP4400M3BJ-S represents an alternative from the same manufacturer utilizing TVS thyristor technology rather than internal switch technology. This part operates at the same 300V off-state voltage as the original part's working voltage. However, this substitute features a single-element configuration (versus dual circuits) and utilizes a different package form factor (DO-214AA, SMB). Selection of this alternative requires design verification to confirm compatibility with single-circuit protection requirements and PCB layout accommodation for the SMB package.

Both substitute parts are manufactured by Bourns Inc. and carry active product status, ensuring long-term supply chain availability and technical support.

Frequently Asked Questions (FAQ)

Q: Can TBU-PL060-200-WH be used as a direct replacement for TBU-PL050-200-WH?

A: Yes. Both parts share identical mechanical specifications (SMD 6.50mm x 4.00mm), dual-circuit configuration, internal switch technology, and SLIC application compatibility. The TBU-PL060-200-WH provides higher voltage ratings (600V clamping versus 500V, 350V working versus 300V), making it functionally compatible and performance-enhanced for the same application space.

Q: What are the key differences between TBU-PL060-200-WH and TISP4400M3BJ-S?

A: TBU-PL060-200-WH maintains the dual-circuit internal switch architecture of the original part with identical package dimensions. TISP4400M3BJ-S employs TVS thyristor technology with a single element and utilizes a different package form factor (DO-214AA, SMB). Circuit topology and PCB layout requirements differ between these technologies.

Q: Are all substitute parts RoHS compliant?

A: TBU-PL050-200-WH and TBU-PL060-200-WH are both ROHS3 compliant. RoHS compliance status for TISP4400M3BJ-S is not specified in the provided data.

Q: What is the impact of the higher voltage ratings in TBU-PL060-200-WH?

A: The increased clamping voltage (600V versus 500V) and working voltage (350V versus 300V) provide additional safety margin and protection headroom in the application circuit. These higher ratings do not negatively impact compatibility; they represent an enhancement to the protection characteristics.

Q: Can TISP4400M3BJ-S replace both circuits provided by TBU-PL050-200-WH?

A: TISP4400M3BJ-S contains a single element, whereas TBU-PL050-200-WH provides dual circuits. Application requirements must be evaluated to determine if single-element protection is sufficient or if dual-circuit protection is mandatory for the intended use case.
