Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, meeting regulatory and environmental requirements equivalent to the EL1117(TA)-VG.

TCLT1107 provides the closest electrical match to the EL1117(TA)-VG, with identical Current Transfer Ratio specifications (80% Min, 160% Max @ 5mA) and matching input/output characteristics. This part is recommended for direct substitution in applications where the EL1117(TA)-VG is unavailable. TCLT1107 inventory availability is 9,182 pieces.

TCLT1106 offers higher Current Transfer Ratio performance (100% Min, 300% Max @ 5mA) and is suitable for applications requiring enhanced gain characteristics. This part maintains all critical isolation and output specifications. TCLT1106 inventory availability is 5,900 pieces.

TCLT1109 provides maximum Current Transfer Ratio performance (200% Min, 400% Max @ 5mA) for applications requiring the highest gain margin. This part is available in the largest quantity (19,996 pieces) and maintains all critical specifications.

TCLT1103 offers moderate Current Transfer Ratio performance (100% Min, 200% Max @ 10mA) and is suitable for general-purpose applications. TCLT1103 inventory availability is 9,829 pieces.

TCLT1102 provides lower Current Transfer Ratio performance (63% Min, 125% Max @ 10mA) and is suitable for applications with lower gain requirements. TCLT1102 inventory availability is 3,190 pieces.

TCLT1100 offers the widest Current Transfer Ratio range (50% Min, 600% Max @ 5mA) and is suitable for applications requiring maximum flexibility in gain selection. TCLT1100 inventory availability is 9,193 pieces.

All substitute parts operate within the -55°C to 100°C temperature range, which encompasses the lower end of the EL1117(TA)-VG operating range (-55°C to 110°C). Applications requiring operation above 100°C must retain the EL1117(TA)-VG.

TCLT1107 operates at maximum output voltage of 70V compared to the EL1117(TA)-VG specification of 80V. Applications requiring output voltages above 70V must use TCLT1100, TCLT1102, TCLT1103, TCLT1106, or TCLT1109.

Frequently Asked Questions (FAQ)

Q: Can TCLT1107 be used as a direct replacement for EL1117(TA)-VG?

A: TCLT1107 is functionally equivalent to EL1117(TA)-VG for applications operating within -55°C to 100°C and requiring maximum output voltage of 70V or less. Both parts share identical Current Transfer Ratio specifications (80% Min, 160% Max @ 5mA), 5000Vrms isolation, single-channel transistor output with base, 50mA output current, and surface mount packaging. TCLT1107 is suitable for direct substitution in these applications.

Q: What is the difference between the substitute parts in terms of Current Transfer Ratio?

A: Current Transfer Ratio varies across the substitute parts to accommodate different application requirements. TCLT1100 provides the widest range (50% to 600%), TCLT1109 provides high performance (200% to 400%), TCLT1106 provides moderate-high performance (100% to 300%), TCLT1103 provides moderate performance (100% to 200%), TCLT1107 provides standard performance (80% to 160%), and TCLT1102 provides lower performance (63% to 125%). Selection depends on the specific gain requirements of the application circuit.

Q: Are all substitute parts compatible with the same PCB layout as EL1117(TA)-VG?

A: All substitute parts use identical 6-SOIC (0.295", 7.50mm Width) surface mount packaging with 5 leads. PCB layouts designed for EL1117(TA)-VG are compatible with all listed substitute parts without modification.

Q: What is the operating temperature limitation when using substitute parts?

A: All substitute parts operate within -55°C to 100°C. The EL1117(TA)-VG extends operation to 110°C. Applications requiring operation between 100°C and 110°C must use the EL1117(TA)-VG.

Q: Does TCLT1107 have any output voltage limitations compared to EL1117(TA)-VG?

A: TCLT1107 specifies maximum output voltage of 70V, while EL1117(TA)-VG specifies 80V. All other substitute parts (TCLT1100, TCLT1102, TCLT1103, TCLT1106, TCLT1109) specify 80V maximum output voltage. Applications requiring output voltages above 70V should use TCLT1100, TCLT1102, TCLT1103, TCLT1106, TCLT1109, or retain EL1117(TA)-VG.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the environmental and regulatory compliance of EL1117(TA)-VG.

Q: What is the difference in switching speed between EL1117(TA)-VG and the substitute parts?

A: EL1117(TA)-VG specifies Turn On/Turn Off Time of 4µs and 3µs respectively, with Rise/Fall Time of 2µs and 3µs. All substitute parts specify Turn On/Turn Off Time of 6µs and 5µs, with Rise/Fall Time of 3µs and 4.7µs. Applications with strict timing requirements below 6µs turn-on time should retain EL1117(TA)-VG.

Q: Which substitute part has the best inventory availability?

A: TCLT1109 has the highest inventory availability with 19,996 pieces in stock, followed by TCLT1103 with 9,829 pieces and TCLT1107 with 9,182 pieces.
