Key Parameters

Substitute Part Grouping Explanation

The TLP250H(LF1,F) qualifies as a direct substitute for the TLP250(MBSKO-LF1,F) based on the following critical parameters:

• Single Channel Configuration: Both parts feature one isolated channel for gate drive applications
• Isolation Voltage: Both maintain 3750Vrms isolation rating
• Common Mode Transient Immunity: Both specify 40kV/µs CMTI performance
• Output Configuration: Both employ push-pull, totem pole output topology
• Output Current: Both deliver 2.5 A per channel
• Supply Voltage Range: Both operate across 10V ~ 30V
• Operating Temperature Range: Both support -40°C ~ 125°C
• Package Type: Both use 8-SMD, Gull Wing surface mount configuration
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)
• Regulatory Compliance: Both ROHS3 compliant and EAR99 classified

The primary distinction is product status: the substitute part is active and currently in production, whereas the original is obsolete.

Engineering Selection Recommendations

The TLP250H(LF1,F) is the direct functional equivalent for applications currently using the obsolete TLP250(MBSKO-LF1,F). Selection is based on:

• Identical Electrical Performance: All critical isolation, switching, and output parameters match between the two parts
• Active Product Status: The substitute part is in active production with established supply chains, eliminating obsolescence risk
• Regulatory Alignment: Both parts maintain identical ROHS3 compliance and EAR99 classification, ensuring no regulatory complications in design transitions
• Package Compatibility: Identical 8-SMD, Gull Wing surface mount configuration enables direct PCB layout compatibility without redesign

For new designs or system refreshes, the TLP250H(LF1,F) should be specified as the primary component. For legacy system support requiring the original part number, the substitute provides equivalent performance with improved availability.

Frequently Asked Questions (FAQ)

Q: Can TLP250H(LF1,F) be used as a direct replacement for TLP250(MBSKO-LF1,F) in existing designs?

A: Yes. Both parts share identical electrical specifications across isolation voltage, output current, supply voltage range, operating temperature, and output topology. The 8-SMD, Gull Wing package is identical, enabling direct PCB substitution without layout modifications.

Q: What is the primary reason for substitution?

A: The TLP250(MBSKO-LF1,F) is classified as obsolete. The TLP250H(LF1,F) is the active production equivalent from the same manufacturer, ensuring continued component availability and supply chain stability.

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

A: No. Both parts are ROHS3 compliant, EAR99 classified, and carry MSL 1 (Unlimited) moisture sensitivity ratings. No regulatory or compliance adjustments are required when transitioning between these parts.

Q: What packaging options are available for this substitution?

A: Both the original and substitute part are supplied in 8-SMD, Gull Wing surface mount configuration. No alternative packaging variants are specified for this substitution pair.

Q: Are timing specifications identical between the two parts?

A: The substitute part specifies propagation delay (500ns maximum for both tpLH and tpHL) and rise/fall times (50ns typical). These timing parameters were not provided for the original part specification. Applications requiring specific timing performance should reference the TLP250H(LF1,F) datasheet for detailed timing characteristics.
