Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Criteria:

• Voltage - Isolation: minimum 5000Vrms (equal or greater)
• Output Type: Transistor
• Input Type: DC
• Number of Channels: 1
• Voltage - Output (Max): 80V or greater
• Current - Output / Channel: 50mA or greater
• Operating Temperature Range: -55°C to 110°C or wider
• Package compatibility: 4-DIP through-hole or surface-mount variants

Flexible Parameters (within acceptable ranges):

• Current Transfer Ratio: may vary within design specifications
• Vce Saturation: may vary within acceptable switching performance
• Rise / Fall Time: may vary within acceptable switching speed
• Voltage - Forward (Vf): minor variations acceptable

Substitute parts are grouped by mounting type: through-hole 4-DIP packages maintain direct pin compatibility, while surface-mount variants require PCB layout modifications but provide equivalent electrical performance.

Engineering Selection Recommendations

Direct Pin-Compatible Substitutes (4-DIP Through-Hole):

TLP785(F), TLP785(Y,F), and VO618A-3 are direct mechanical and electrical substitutes for the EL816(D)-V in through-hole applications. All three maintain identical 4-DIP package dimensions (0.300", 7.62mm) and pin configurations, enabling direct socket replacement without PCB modification.

TLP785(F) provides the broadest current transfer ratio range (50% to 600% @ 5mA) and is manufactured by Toshiba Semiconductor with ROHS3 compliance. This variant offers 2332 units in current inventory.

TLP785(Y,F) is also manufactured by Toshiba Semiconductor with a narrower current transfer ratio range (50% to 150% @ 5mA) and ROHS3 compliance. This variant has 966 units in inventory.

VO618A-3 is manufactured by Vishay Semiconductor Opto Division with a higher isolation voltage rating of 5300Vrms and ROHS3 compliance. This variant provides 5365 units in current inventory and features improved switching characteristics with 2µs rise time and 2µs fall time.

Surface-Mount Alternative:

TLP785(GR-TP6,F) is a surface-mount variant in 4-SMD gull-wing package manufactured by Toshiba Semiconductor. This option requires PCB layout redesign but provides 13874 units in inventory, the highest stock availability among all substitutes. Current transfer ratio range is 100% to 300% @ 5mA with RoHS compliance.

Compliance and Regulatory Status:

All substitute parts maintain RoHS compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original EL816(D)-V specifications. VO618A-3 and TLP785(F) carry REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8541.49.8000.

Frequently Asked Questions (FAQ)

Q: Can TLP785(F) directly replace EL816(D)-V in existing designs?

A: Yes. TLP785(F) is a direct pin-compatible substitute with identical 4-DIP through-hole package dimensions. Both parts share the same isolation voltage (5000Vrms), output voltage rating (80V maximum), output current capability (50mA), and operating temperature range (-55°C to 110°C). No PCB modifications are required.

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

A: Both are Toshiba 4-DIP through-hole optoisolators with 5000Vrms isolation. The primary difference is the current transfer ratio range: TLP785(F) ranges from 50% to 600% @ 5mA, while TLP785(Y,F) ranges from 50% to 150% @ 5mA. TLP785(F) provides a wider performance envelope and is suitable for applications requiring higher current transfer ratios.

Q: Why would I choose VO618A-3 over TLP785(F)?

A: VO618A-3 offers a higher isolation voltage rating (5300Vrms versus 5000Vrms), providing additional safety margin in high-voltage isolation applications. VO618A-3 also features faster switching characteristics with 2µs rise and fall times compared to TLP785(F) specifications. Both maintain identical 4-DIP package compatibility and 50mA output current capability.

Q: Is TLP785(GR-TP6,F) compatible with through-hole PCB designs?

A: No. TLP785(GR-TP6,F) is a surface-mount component in 4-SMD gull-wing package and requires surface-mount PCB layout. It cannot be used in through-hole applications without significant PCB redesign. However, it provides the highest inventory availability (13874 units) and is electrically equivalent to the EL816(D)-V.

Q: What are the key electrical differences between EL816(D)-V and its substitutes?

A: The EL816(D)-V has a higher minimum current transfer ratio (300% @ 5mA) and lower maximum Vce saturation (200mV) compared to most substitutes. TLP785(F) and TLP785(GR-TP6,F) can achieve the same maximum current transfer ratio (600% and 300% respectively), but with higher saturation voltages (400mV). VO618A-3 features the highest isolation voltage (5300Vrms) and fastest switching times. All substitutes meet or exceed the output voltage and current specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed—TLP785(F), TLP785(GR-TP6,F), TLP785(Y,F), and VO618A-3—are RoHS compliant. EL816(D)-V, TLP785(F), TLP785(Y,F), and VO618A-3 carry ROHS3 certification. TLP785(GR-TP6,F) carries RoHS compliance designation. All parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the current inventory status for each substitute?

A: TLP785(GR-TP6,F) has the highest availability with 13874 units in stock. VO618A-3 has 5365 units. TLP785(F) has 2332 units. TLP785(Y,F) has 966 units. The original EL816(D)-V has 714 units in stock.

Q: Can I use these substitutes in applications requiring the EL816(D)-V's specific current transfer ratio range?

A: Application-specific requirements must be evaluated. The EL816(D)-V specifies 300% to 600% @ 5mA current transfer ratio. TLP785(F) matches this range (50% to 600%), providing full compatibility. TLP785(GR-TP6,F) ranges from 100% to 300%, which covers the lower portion of the EL816(D)-V range. TLP785(Y,F) ranges from 50% to 150%, which does not fully cover the EL816(D)-V specification. VO618A-3 ranges from 100% to 200% @ 1mA, which also does not fully match the EL816(D)-V specification at 5mA test current.
