Key Parameters

Substitute Part Grouping Explanation

Substitution of the FOD2743BT is determined by strict equivalence across the following critical parameters:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Transistor
• Voltage - Output (Max): 70V
• Current - Output / Channel: 50mA
• Current Transfer Ratio: 50% (Min) to 100% (Max) @ 1mA
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 8-DIP (0.400", 10.16mm)
• Input Type: DC

The FOD2743BTV qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The FOD2743BTV is the direct equivalent substitute for the obsolete FOD2743BT. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

The FOD2743BTV holds active product status with ROHS3 compliance certification, providing assurance of ongoing manufacturing support and regulatory alignment. The FOD2743BT, classified as obsolete, presents supply chain risk and lacks current compliance documentation.

Selection of the FOD2743BTV is supported by product availability (1510 pcs in stock versus 808 pcs for the FOD2743BT) and active manufacturing status, making it the preferred choice for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the FOD2743BTV replace the FOD2743BT in existing designs?

A: Yes. The FOD2743BTV is electrically and mechanically identical to the FOD2743BT. All electrical parameters, isolation voltage, output current, saturation voltage, and operating temperature range are equivalent. The 8-DIP package dimensions and pin configuration are identical, enabling direct substitution without circuit modification.

Q: What is the difference between FOD2743BT and FOD2743BTV?

A: The primary differences are product status and packaging format. The FOD2743BT is obsolete and supplied in bulk packaging. The FOD2743BTV is active, supplied in tube packaging, and carries ROHS3 compliance certification. Electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: The FOD2743BTV carries ROHS3 compliance certification and has active product status. The FOD2743BT is obsolete and does not include current compliance documentation. Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99).

Q: What packaging formats are available?

A: The FOD2743BT is supplied in bulk packaging. The FOD2743BTV is supplied in tube packaging. Both use the 8-DIP (0.400", 10.16mm) package case. Packaging format does not affect electrical performance or circuit compatibility.

Q: Is the FOD2743BTV suitable for new production designs?

A: Yes. The FOD2743BTV is the recommended choice for new designs due to active product status, ROHS3 compliance, and confirmed supply availability. The obsolete status of the FOD2743BT makes it unsuitable for new production commitments.
