Engineering Selection Recommendations
All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. The EL1014(TA)-G and substitute parts from Vishay Semiconductor Opto Division (TCLT series and VOL617A series) are functionally equivalent within the specified electrical and mechanical parameters.
Substitution Compatibility by Operating Temperature Range:
Parts supporting the full -55°C to 110°C temperature range of the EL1014(TA)-G are VOL617A-1X001T and VOL617A-2X001T. These maintain identical maximum output voltage (80V) and saturation voltage characteristics.
Parts with -55°C to 100°C operating range (TCLT1000, TCLT1002, TCLT1003, TCLT1005, TCLT1006, TCLT1007, TCLT1008, TCLT1009) are suitable for applications not requiring operation above 100°C.
Substitution Compatibility by Output Voltage:
Parts rated for 80V maximum output voltage (EL1014(TA)-G, VOL617A-1X001T, VOL617A-2X001T) are direct substitutes for circuits requiring the full 80V output capability.
Parts rated for 70V maximum output voltage (TCLT series) are suitable for applications with output voltage requirements not exceeding 70V.
Substitution Compatibility by Saturation Voltage:
EL1014(TA)-G with 300mV maximum Vce saturation is directly compatible with TCLT series parts (300mV maximum).
VOL617A series parts with 400mV maximum Vce saturation introduce slightly higher saturation voltage and are suitable where this parameter is not critical to circuit performance.
All substitute parts maintain identical isolation voltage (5000Vrms), single-channel configuration, transistor output type, DC input type, 50mA output current, and 4-SOP package format.
Frequently Asked Questions (FAQ)
Q: Can TCLT1000 through TCLT1009 directly replace EL1014(TA)-G in all applications?
A: TCLT series parts are functionally equivalent for applications operating within -55°C to 100°C temperature range and with output voltage requirements not exceeding 70V. Applications requiring operation above 100°C or output voltages above 70V require VOL617A series substitutes.
Q: What is the difference between TCLT1000, TCLT1002, TCLT1003, TCLT1005, TCLT1006, TCLT1007, TCLT1008, and TCLT1009?
A: All TCLT variants maintain identical isolation voltage, package, and output specifications. The primary difference is Current Transfer Ratio (CTR) specification at different test currents. TCLT1000 specifies 50% to 600% CTR at 5mA. TCLT1002 specifies 63% to 125% CTR at 10mA. TCLT1003 specifies 100% to 200% CTR at 10mA. TCLT1005 specifies 50% to 150% CTR at 5mA. TCLT1006 specifies 100% to 300% CTR at 5mA. TCLT1007 specifies 80% to 160% CTR at 5mA. TCLT1008 specifies 130% to 260% CTR at 5mA. TCLT1009 specifies 200% to 400% CTR at 5mA. Selection depends on required CTR performance for the specific application.
Q: Are VOL617A-1X001T and VOL617A-2X001T interchangeable with EL1014(TA)-G?
A: VOL617A-1X001T and VOL617A-2X001T are functionally equivalent substitutes. Both maintain 5000Vrms isolation, 80V maximum output voltage, 50mA output current, and -55°C to 110°C operating temperature range. The primary difference is Current Transfer Ratio specification. VOL617A-1X001T specifies 40% to 80% CTR at 5mA. VOL617A-2X001T specifies 63% to 125% CTR at 5mA. Selection depends on required CTR performance.
Q: What is the significance of the 4-SOP (2.54mm) package specification?
A: The 4-SOP (2.54mm) package is a surface mount configuration with 2.54mm lead spacing. All substitute parts maintain this identical package format, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes. No board redesign is required when substituting between parts with matching 4-SOP package specifications.
Q: Can I use TCLT series parts in applications requiring -55°C to 110°C operation?
A: TCLT series parts are rated for -55°C to 100°C operation. Applications requiring operation above 100°C must use VOL617A-1X001T or VOL617A-2X001T, which are rated for -55°C to 110°C.
Q: What packaging options are available for substitute parts?
A: EL1014(TA)-G is supplied in Tape & Reel (TR) packaging. TCLT1000 and TCLT1005 through TCLT1008 are supplied in Tape & Reel (TR) packaging. TCLT1002, TCLT1003, and TCLT1009 are supplied in Cut Tape (CT) & Digi-Reel® packaging. VOL617A-1X001T and VOL617A-2X001T are supplied in Tape & Reel (TR) packaging. Packaging selection depends on assembly process requirements and volume specifications.
Q: Are all substitute parts ROHS3 compliant?
A: All substitute parts listed are ROHS3 compliant, matching the compliance status of EL1014(TA)-G. This ensures regulatory conformance for applications subject to ROHS3 requirements.
Q: What is the Moisture Sensitivity Level (MSL) for substitute parts?
A: All substitute parts maintain MSL 1 (Unlimited) rating, identical to EL1014(TA)-G. This indicates unlimited shelf life under normal storage conditions without special moisture control requirements.
