Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EL816(X)-V is determined by the following critical parameters:

Mandatory Matching Criteria:

• Isolation voltage: 5000Vrms or higher
• Number of channels: 1
• Output type: Transistor
• Maximum output voltage: 80V
• Output current capability: 50mA minimum
• Operating temperature range: -55°C to 110°C minimum
• Package/Case: 4-DIP (0.300", 7.62mm) for through-hole mounting compatibility

Acceptable Variation Parameters:

• Current Transfer Ratio: Minimum 50% @ 5mA or equivalent test condition; Maximum 150% or higher
• Vce Saturation: Up to 400mV (higher than main part specification)
• Forward voltage (Vf): 1.1V to 1.2V range
• Rise/Fall times: 2µs to 4µs range
• Turn-on/turn-off times: 2µs to 3µs range

Parts meeting these criteria are classified as direct substitutes for the EL816(X)-V in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

TLP785(F) - Toshiba Semiconductor

The TLP785(F) is a direct substitute for through-hole applications. Both parts share identical isolation voltage (5000Vrms), output voltage rating (80V), output current (50mA), and operating temperature range (-55°C to 110°C). The TLP785(F) exhibits lower minimum CTR (50% vs. 100%) but higher maximum CTR (600% vs. 200%), with faster rise/fall times (2µs/3µs vs. 4µs/3µs). Vce saturation is higher at 400mV compared to 200mV. The part is ROHS3 compliant with MSL 1 rating. Inventory availability is 2332 pieces.

TLP785(Y,F) - Toshiba Semiconductor

The TLP785(Y,F) is a through-hole substitute with matching isolation voltage, output specifications, and temperature range. CTR range is 50% to 150%, narrower than the main part. Vce saturation reaches 400mV. This variant is RoHS compliant with MSL 1 rating. Inventory is 966 pieces.

TLP785(GR-TP6,F) - Toshiba Semiconductor

This variant differs in mounting type (surface mount, 4-SMD gull wing) and is not suitable for through-hole applications requiring the 4-DIP package. It is listed for reference only.

VO618A-3 - Vishay Semiconductor Opto Division

The VO618A-3 is a through-hole substitute with higher isolation voltage (5300Vrms vs. 5000Vrms), matching output specifications (80V, 50mA), and identical operating temperature range. CTR is specified at different test condition (1mA vs. 5mA) with 100% to 200% range. Vce saturation is 400mV. The part is ROHS3 compliant with MSL 1 rating and REACH unaffected status. Inventory is 5365 pieces.

All substitute parts maintain compliance with RoHS3 and MSL 1 requirements. Selection should be based on circuit-specific requirements for CTR performance, saturation voltage tolerance, and available inventory.

Frequently Asked Questions (FAQ)

Q: Can TLP785(F) replace EL816(X)-V in a through-hole PCB design?

A: Yes. Both parts use 4-DIP (0.300", 7.62mm) through-hole packages with identical pin spacing and mounting requirements. Electrical specifications for isolation voltage (5000Vrms), output voltage (80V), output current (50mA), and operating temperature (-55°C to 110°C) are equivalent. Design verification should confirm CTR performance tolerance, as TLP785(F) has lower minimum CTR (50% vs. 100%) but higher maximum CTR (600% vs. 200%).

Q: What is the difference between TLP785(F) and TLP785(Y,F)?

A: Both are through-hole 4-DIP packages from Toshiba with identical isolation voltage and output ratings. The primary difference is CTR range: TLP785(F) spans 50% to 600%, while TLP785(Y,F) spans 50% to 150%. Selection depends on circuit requirements for current transfer ratio performance.

Q: Why is TLP785(GR-TP6,F) not recommended as a substitute?

A: TLP785(GR-TP6,F) uses surface-mount 4-SMD gull wing packaging, incompatible with through-hole PCB designs requiring 4-DIP packages. It is not a mechanical substitute for the EL816(X)-V.

Q: How does VO618A-3 differ from the main part?

A: VO618A-3 provides higher isolation voltage (5300Vrms vs. 5000Vrms) and is manufactured by Vishay instead of Everlight. Output specifications (80V, 50mA) and operating temperature range are identical. CTR is specified at 1mA test condition rather than 5mA. Vce saturation is higher at 400mV. The higher isolation voltage makes it suitable for applications requiring enhanced isolation margin.

Q: Are all substitute parts RoHS compliant?

A: Yes. EL816(X)-V is ROHS3 compliant. TLP785(F) and VO618A-3 are ROHS3 compliant. TLP785(Y,F) is RoHS compliant. All parts have MSL 1 (Unlimited) moisture sensitivity rating.

Q: What inventory levels are available for each substitute?

A: EL816(X)-V: 689 pieces; TLP785(F): 2332 pieces; TLP785(Y,F): 966 pieces; VO618A-3: 5365 pieces.
