Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EL1119(TA)-VG are qualified based on the following criteria:

Core Electrical Compatibility:

• Voltage - Isolation: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Type: Transistor with Base (mandatory match)
• Input Type: DC (mandatory match)
• Voltage - Output (Max): 80V or higher
• Current - Output / Channel: 50mA or higher
• Operating Temperature Range: Must encompass or exceed -55°C ~ 110°C

Mechanical Compatibility:

• Mounting Type: Surface Mount (mandatory match)
• Package / Case: 6-SOIC (0.295", 7.50mm Width), 5 Leads (mandatory match)

Compliance & Status:

• Product Status: Active
• RoHS Status: RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The following Vishay Semiconductor Opto Division parts meet these substitution criteria: TCLT1100, TCLT1102, TCLT1103, TCLT1106, TCLT1107, and TCLT1109. All substitute parts maintain identical isolation voltage, channel count, output configuration, and physical packaging while offering variations in current transfer ratio characteristics and switching speed parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and RoHS3 compliance, ensuring regulatory and supply chain continuity. The primary distinction between the EL1119(TA)-VG and Vishay TCLT series substitutes lies in switching speed characteristics and operating temperature upper limit.

EL1119(TA)-VG Characteristics:

• Faster switching performance: 4µs turn-on, 3µs turn-off, 2µs rise time, 3µs fall time
• Extended operating temperature range: -55°C ~ 110°C
• Higher Vce saturation: 400mV maximum
• Higher forward voltage: 1.5V maximum

Vishay TCLT Series Characteristics:

• Slower switching performance: 6µs turn-on, 5µs turn-off, 3µs rise time, 4.7µs fall time
• Standard operating temperature range: -55°C ~ 100°C
• Lower Vce saturation: 300mV maximum
• Lower forward voltage: 1.25V typical

Selection between the main part and substitutes depends on application-specific requirements for switching speed and temperature operation. Applications requiring operation above 100°C must use the EL1119(TA)-VG. Applications with relaxed switching speed requirements and operation within -55°C ~ 100°C may use any TCLT substitute. All parts share identical isolation voltage, channel configuration, output type, and physical packaging.

Frequently Asked Questions (FAQ)

Q: Can TCLT1100, TCLT1102, TCLT1103, TCLT1106, TCLT1107, or TCLT1109 directly replace EL1119(TA)-VG in existing designs?

A: Direct replacement is possible for applications operating within -55°C ~ 100°C temperature range and tolerating slower switching times (6µs turn-on versus 4µs). All parts maintain identical 5000Vrms isolation, single-channel transistor output configuration, 50mA output current capability, and 6-SOIC 5-lead physical packaging. Pin-to-pin compatibility is confirmed across all substitute parts.

Q: What are the key differences in current transfer ratio between EL1119(TA)-VG and TCLT substitutes?

A: EL1119(TA)-VG specifies 200% to 400% current transfer ratio at 5mA input. TCLT substitutes vary: TCLT1100 (50% to 600% @ 5mA), TCLT1102 (63% to 125% @ 10mA), TCLT1103 (100% to 200% @ 10mA), TCLT1106 (100% to 300% @ 5mA), TCLT1107 (80% to 160% @ 5mA), and TCLT1109 (200% to 400% @ 5mA). Current transfer ratio selection depends on input drive current and output switching requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. EL1119(TA)-VG and all listed Vishay TCLT substitutes (TCLT1100, TCLT1102, TCLT1103, TCLT1106, TCLT1107, TCLT1109) are RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard manufacturing and storage processes.

Q: What is the maximum operating temperature for each part?

A: EL1119(TA)-VG operates from -55°C to 110°C. All Vishay TCLT substitutes operate from -55°C to 100°C. Applications requiring operation above 100°C must use EL1119(TA)-VG.

Q: How do switching times compare between EL1119(TA)-VG and TCLT substitutes?

A: EL1119(TA)-VG provides faster switching: 4µs turn-on and 3µs turn-off with 2µs rise and 3µs fall times. All TCLT substitutes have 6µs turn-on and 5µs turn-off with 3µs rise and 4.7µs fall times. Applications with strict timing requirements below 6µs switching speed require EL1119(TA)-VG.

Q: Is the 70V maximum output voltage of TCLT1107 a limitation?

A: TCLT1107 specifies 70V maximum output voltage compared to 80V for EL1119(TA)-VG and other TCLT substitutes. Applications requiring output voltage operation above 70V must use EL1119(TA)-VG, TCLT1100, TCLT1102, TCLT1103, TCLT1106, or TCLT1109.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. EL1119(TA)-VG and all Vishay TCLT substitutes are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
