Engineering Selection Recommendations

Substitute Selection Based on Operating Temperature Requirements:

For applications requiring the full operating temperature range of -55°C to 110°C, select VOL617A-1X001T or VOL617A-2X001T. These parts maintain the same maximum output voltage (80V) and operating temperature range as the EL1010(TA)-G. Both are ROHS3 compliant with MSL 1 (Unlimited) rating.

Substitute Selection for Standard Temperature Range (-55°C to 100°C):

TCLT1000, TCLT1002, TCLT1003, TCLT1005, TCLT1006, TCLT1007, TCLT1008, and TCLT1009 are suitable for applications operating within -55°C to 100°C. All are ROHS3 compliant with MSL 1 (Unlimited) rating. These parts operate at maximum output voltage of 70V, which is 10V lower than the EL1010(TA)-G.

Current Transfer Ratio Selection:

Substitute parts are available with different Current Transfer Ratio specifications:

TCLT1000: 50% to 600% @ 5mA
TCLT1002: 63% to 125% @ 10mA
TCLT1003: 100% to 200% @ 10mA
TCLT1005: 50% to 150% @ 5mA
TCLT1006: 100% to 300% @ 5mA
TCLT1007: 80% to 160% @ 5mA
TCLT1008: 130% to 260% @ 5mA
TCLT1009: 200% to 400% @ 5mA

Select the CTR grade matching your circuit's input current and required gain characteristics.

Vce Saturation Consideration:

VOL617A-1X001T and VOL617A-2X001T have Vce Saturation (Max) of 400mV, compared to 300mV for EL1010(TA)-G and TCLT series. Applications sensitive to saturation voltage drop should account for this 100mV difference.

Compliance Status:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the EL1010(TA)-G specification.

Frequently Asked Questions (FAQ)

Q: Can TCLT1000 through TCLT1009 directly replace EL1010(TA)-G in all applications?

A: TCLT series parts are compatible with EL1010(TA)-G for applications operating within -55°C to 100°C. The maximum output voltage is 70V versus 80V for EL1010(TA)-G. Applications requiring operation above 100°C or maximum output voltage of 80V should use VOL617A-1X001T or VOL617A-2X001T instead.

Q: What is the difference between TCLT1000 and TCLT1008?

A: Both parts share identical isolation voltage (5000Vrms), channel count (1), output type (Transistor), package (4-SOP), and operating temperature range (-55°C to 100°C). The primary difference is Current Transfer Ratio: TCLT1000 ranges from 50% to 600% @ 5mA, while TCLT1008 ranges from 130% to 260% @ 5mA. Select based on your circuit's input current and required gain.

Q: Are VOL617A-1X001T and VOL617A-2X001T interchangeable?

A: Both parts share identical electrical specifications including isolation voltage (5000Vrms), output voltage (80V), operating temperature (-55°C to 110°C), and Vce Saturation (400mV). The difference is Current Transfer Ratio: VOL617A-1X001T ranges from 40% to 80% @ 5mA, while VOL617A-2X001T ranges from 63% to 125% @ 5mA. Select based on your circuit's input current requirements.

Q: What packaging options are available for substitute parts?

A: TCLT1000, TCLT1005, TCLT1006, TCLT1007, TCLT1008 are supplied in Tape & Reel (TR). TCLT1002, TCLT1003, TCLT1009 are supplied in Cut Tape (CT) & Digi-Reel®. VOL617A-1X001T and VOL617A-2X001T are supplied in Tape & Reel (TR). All maintain the same 4-SOP surface mount package form factor.

Q: Is the 10V difference in maximum output voltage (70V vs 80V) significant for substitution?

A: The output voltage difference between TCLT series (70V max) and EL1010(TA)-G or VOL617A series (80V max) is significant only if your application circuit operates near the 70V limit. For applications with output voltage headroom below 70V, TCLT series substitution is valid. For applications requiring the full 80V capability, use EL1010(TA)-G, VOL617A-1X001T, or VOL617A-2X001T.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All identified substitute parts (TCLT1000, TCLT1002, TCLT1003, TCLT1005, TCLT1006, TCLT1007, TCLT1008, TCLT1009, VOL617A-1X001T, VOL617A-2X001T) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching EL1010(TA)-G specification.

Q: What is the significance of Current Transfer Ratio test current (5mA vs 10mA)?

A: Current Transfer Ratio is measured at a specified input LED current. TCLT1000, TCLT1005, TCLT1006, TCLT1007, TCLT1008, TCLT1009, VOL617A-1X001T, and VOL617A-2X001T are tested at 5mA input current. TCLT1002 and TCLT1003 are tested at 10mA input current. Select parts based on your circuit's actual input current to ensure the specified CTR range applies to your operating condition.
