Key Parameters

Substitute Part Grouping Explanation

Substitution for the TCED1100 is determined by the following critical parameters:

• Voltage isolation rating of 5000Vrms or higher
• Single channel configuration
• 4-DIP package format (0.300", 7.62mm)
• Through-hole mounting type
• Output current capability of 80mA or greater
• Maximum output voltage of 35V or higher
• Operating temperature range compatibility
• ROHS3 compliance

The TCED1100 transistor output can be substituted with Darlington output optoisolators that meet or exceed these electrical specifications, as Darlington configurations provide superior current transfer characteristics while maintaining pin-compatible 4-DIP packaging.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain ROHS3 compliance and active product status, ensuring regulatory compliance and long-term availability.

SFH619A offers the highest isolation voltage (5300Vrms) and current transfer ratio (1000% @ 1mA), with extended low-temperature operating range (-55°C). This part is suitable for applications requiring maximum performance margins and wide temperature operation.

EL815-V and LTV-815 provide direct electrical equivalence to the TCED1100 with identical isolation voltage (5000Vrms), output voltage (35V), and output current (80mA) specifications. Both maintain the same saturation voltage (1V) and package format. EL815-V extends the upper operating temperature to 110°C. LTV-815 maintains the standard temperature range (-30°C ~ 100°C) and offers the highest inventory availability (45200 pcs).

Frequently Asked Questions (FAQ)

Q: Can the TCED1100 be directly replaced with SFH619A?

A: Yes. SFH619A is pin-compatible in 4-DIP packaging and exceeds all critical electrical specifications. The higher isolation voltage (5300Vrms vs 5000Vrms) and current transfer ratio (1000% vs 600%) provide improved performance margins. The Darlington output configuration offers faster switching characteristics.

Q: What is the difference between transistor and Darlington output types?

A: Both are functionally compatible in this application. Darlington output (SFH619A, EL815-V, LTV-815) provides higher current gain and faster switching response. Transistor output (TCED1100) offers lower saturation voltage. Selection depends on circuit requirements for switching speed versus saturation voltage performance.

Q: Are EL815-V and LTV-815 interchangeable?

A: Yes. Both parts share identical isolation voltage (5000Vrms), output voltage (35V), output current (80mA), and saturation voltage (1V) specifications. EL815-V operates to 110°C maximum; LTV-815 operates to 100°C maximum. Package and pin configuration are identical.

Q: Does the higher isolation voltage of SFH619A (5300Vrms) affect circuit design?

A: No. Higher isolation voltage is a superset specification that maintains backward compatibility. Circuits designed for 5000Vrms operation function correctly with 5300Vrms components.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TCED1100, SFH619A, EL815-V, and LTV-815 are all ROHS3 compliant, meeting regulatory requirements for new production and field replacement applications.
