Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EL1110(TA)-VG are qualified based on strict electrical and mechanical compatibility criteria. All substitute parts must maintain the following core parameters:

Critical Matching Parameters:

• Isolation voltage: 5000Vrms (exact match required)
• Number of channels: 1 (exact match required)
• Output type: Transistor with Base (exact match required)
• Input type: DC (exact match required)
• Maximum output voltage: 80V or greater
• Maximum output current: 50mA or greater per channel
• Mounting type: Surface Mount (exact match required)
• Package footprint: 6-SOIC (0.295", 7.50mm Width), 5 Leads (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

Allowable Parameter Variations: Current Transfer Ratio specifications may vary within the ranges provided by each manufacturer. Turn-on/turn-off times and rise/fall times may differ. Forward voltage (Vf) and Vce saturation values may vary within acceptable limits. Operating temperature maximum may be lower (100°C vs. 110°C) without affecting substitution eligibility.

All five substitute parts listed (TCLT1100, TCLT1102, TCLT1103, TCLT1106, TCLT1107, TCLT1109) meet these criteria and are manufactured by Vishay Semiconductor Opto Division.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and MSL 1 rating, meeting the same regulatory and environmental standards as the EL1110(TA)-VG. Selection among substitute parts should be based on the specific current transfer ratio requirements of the application:

TCLT1100 provides identical CTR range (50% to 600% @ 5mA) to the main part and represents the closest electrical match. This part is suitable for applications requiring the widest CTR tolerance band.

TCLT1106 offers a higher minimum CTR (100% @ 5mA) with a maximum of 300% @ 5mA, making it appropriate for applications requiring more predictable gain characteristics within a narrower range.

TCLT1109 provides the highest CTR range (200% to 400% @ 5mA), suitable for applications requiring high current transfer efficiency.

TCLT1107 delivers moderate CTR (80% to 160% @ 5mA) with a reduced maximum output voltage of 70V. This part is suitable only for applications where the 70V output voltage limit is acceptable.

TCLT1102 and TCLT1103 operate at different test currents (10mA vs. 5mA) and offer narrower CTR ranges, making them suitable for applications with specific current transfer ratio requirements at higher input currents.

All substitute parts feature improved Vce saturation characteristics (300mV maximum vs. 400mV) and lower forward voltage (1.25V vs. 1.5V), resulting in reduced power dissipation. The maximum operating temperature of 100°C for substitute parts is 10°C lower than the main part; applications requiring operation above 100°C must use the EL1110(TA)-VG.

Frequently Asked Questions (FAQ)

Q: Can TCLT1107 be used as a direct replacement for EL1110(TA)-VG?

A: TCLT1107 is electrically compatible with the EL1110(TA)-VG in all critical parameters except maximum output voltage. TCLT1107 is rated for 70V maximum output, while EL1110(TA)-VG is rated for 80V. If the application requires output voltages between 70V and 80V, TCLT1107 is not suitable. For applications operating at 70V or below, TCLT1107 is a valid substitute.

Q: What is the difference between the CTR specifications at different test currents?

A: Current Transfer Ratio (CTR) is measured at a specified input current. TCLT1102 and TCLT1103 specify CTR at 10mA input current, while EL1110(TA)-VG, TCLT1100, TCLT1106, TCLT1107, and TCLT1109 specify CTR at 5mA input current. The test current affects the measured CTR value. When selecting a substitute, ensure the application input current aligns with the part's CTR specification test current.

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts use the 6-SOIC (0.295", 7.50mm Width) package with 5 leads, identical to the EL1110(TA)-VG. All parts are surface mount components suitable for automated assembly on standard PCB equipment.

Q: What is the impact of the lower maximum operating temperature on substitute parts?

A: Substitute parts are rated for -55°C to 100°C operation, while EL1110(TA)-VG is rated for -55°C to 110°C. If the application requires sustained operation above 100°C, only the EL1110(TA)-VG is suitable. For applications with maximum operating temperatures at or below 100°C, substitute parts are fully qualified.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts carry EAR99 ECCN classification and fall under HTSUS code 8541.49.8000. Substitute parts from Vishay Semiconductor Opto Division also carry REACH Unaffected status.

Q: Which substitute part offers the best performance improvement?

A: Performance improvements depend on application requirements. TCLT1100, TCLT1106, and TCLT1109 all feature lower Vce saturation (300mV vs. 400mV) and lower forward voltage (1.25V vs. 1.5V), reducing power dissipation. TCLT1109 provides the highest CTR range (200% to 400%), while TCLT1106 offers the most stable CTR characteristics (100% to 300%). Selection should be based on specific application current transfer ratio and power dissipation requirements.

Q: Can substitute parts be mixed in the same design?

A: All substitute parts are electrically compatible with the EL1110(TA)-VG and with each other within the specified parameter ranges. However, mixing different part numbers in the same design may complicate inventory management and qualification testing. Standard engineering practice recommends standardizing on a single part number per design unless specific application requirements necessitate multiple variants.
