Engineering Selection Recommendations

Parametric Equivalent (Same Manufacturer):

EL1017(TA)-VG is a direct parametric equivalent to EL1017(TA)-G from Everlight Electronics. Both parts share identical electrical specifications including 80% to 160% current transfer ratio at 5mA, 80V maximum output voltage, and -55°C to 110°C operating temperature range. The sole difference is packaging format: EL1017(TA)-VG is supplied in Tape & Reel format while EL1017(TA)-G is supplied in tube packaging. Both are RoHS3 compliant with MSL 1 rating. Selection between these two depends on assembly process requirements and tape reel compatibility.

Vishay TCLT Series Alternatives:

The Vishay TCLT1000 through TCLT1009 series provides functional substitution with the following considerations:

TCLT1007 offers the closest electrical match to EL1017(TA)-G with identical 80% to 160% current transfer ratio at 5mA. However, maximum output voltage is 70V versus 80V for the Everlight part, and operating temperature upper limit is 100°C versus 110°C. These differences are acceptable for applications not requiring the extended voltage or temperature range.

TCLT1002 and TCLT1003 feature different current transfer ratio specifications measured at 10mA rather than 5mA, making direct comparison of CTR values inappropriate for applications sensitive to input current levels.

TCLT1005 and TCLT1006 provide wider current transfer ratio ranges (50-150% and 100-300% respectively at 5mA), suitable for applications with less stringent CTR tolerance requirements.

TCLT1000, TCLT1008, and TCLT1009 offer progressively higher current transfer ratios (50-600%, 130-260%, and 200-400% respectively), applicable to designs requiring higher gain characteristics.

All Vishay TCLT parts are RoHS3 compliant with MSL 1 rating and maintain the required 5000Vrms isolation, single channel, transistor output, and 4-SOP surface mount configuration.

VOL617A-1X001T Alternative:

VOL617A-1X001T from Vishay provides substitution with 5000Vrms isolation and 80V maximum output voltage matching the EL1017(TA)-G. Current transfer ratio range is 40% to 80% at 5mA, representing lower gain than the primary part. Operating temperature range extends to 110°C matching the Everlight specification. Vce saturation is 400mV versus 300mV for the primary part. This part is suitable for applications where lower current transfer ratio is acceptable and higher saturation voltage is tolerable.

Compliance and Certification:

All listed substitute parts maintain RoHS3 compliance and MSL 1 moisture sensitivity rating. All parts are classified under HTSUS 8541.49.8000 and ECCN EAR99. Selection among qualified alternatives should be based on specific application requirements for current transfer ratio, output voltage rating, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can TCLT1007 directly replace EL1017(TA)-G in all applications?

A: TCLT1007 matches the current transfer ratio specification (80-160% @ 5mA) and maintains 5000Vrms isolation with identical package configuration. However, the maximum output voltage is 70V versus 80V, and the operating temperature upper limit is 100°C versus 110°C. Direct replacement is suitable only for applications operating within these reduced specifications.

Q: What is the difference between EL1017(TA)-G and EL1017(TA)-VG?

A: Both parts are electrically identical with matching specifications across all parameters. The difference is packaging format only: EL1017(TA)-G is supplied in tube packaging while EL1017(TA)-VG is supplied in Tape & Reel format. Selection depends on assembly equipment compatibility and production volume requirements.

Q: Why do some TCLT parts specify current transfer ratio at 10mA instead of 5mA?

A: Current transfer ratio is a function of input current. TCLT1002 and TCLT1003 specify CTR at 10mA input current, while EL1017(TA)-G and most other alternatives specify CTR at 5mA. These specifications are not directly comparable. Applications using 10mA input current should reference the 10mA CTR specification for accurate performance prediction.

Q: Is VOL617A-1X001T suitable for high-current applications?

A: VOL617A-1X001T has a lower current transfer ratio range (40-80% @ 5mA) compared to EL1017(TA)-G (80-160% @ 5mA). This means higher input current is required to achieve the same output current. Additionally, Vce saturation is 400mV versus 300mV, resulting in higher power dissipation. This part is suitable only for applications where lower gain and higher saturation voltage are acceptable.

Q: Can I use TCLT1009 in place of EL1017(TA)-G?

A: TCLT1009 maintains the required 5000Vrms isolation, single channel, transistor output, and 4-SOP package. However, it has significantly higher current transfer ratio (200-400% @ 5mA) and lower maximum output voltage (70V versus 80V). Use TCLT1009 only in applications where higher gain is beneficial and the 70V output voltage limit is acceptable.

Q: What packaging options are available for EL1017(TA)-G equivalents?

A: EL1017(TA)-G is supplied in tube packaging. EL1017(TA)-VG provides the same part in Tape & Reel format. Vishay TCLT series parts are available in Tape & Reel (TCLT1000, TCLT1005, TCLT1006, TCLT1007, TCLT1008) or Cut Tape & Digi-Reel format (TCLT1002, TCLT1003, TCLT1009). VOL617A-1X001T is supplied in Tape & Reel format. Selection should match assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. EL1017(TA)-G, EL1017(TA)-VG, all TCLT series parts (TCLT1000 through TCLT1009), and VOL617A-1X001T are all RoHS3 compliant with MSL 1 moisture sensitivity rating.

Q: What is the primary difference between Everlight and Vishay optoisolators in this category?

A: Both manufacturers provide 5000Vrms isolation optoisolators in 4-SOP packages meeting the same fundamental specifications. Differences exist in current transfer ratio ranges, timing characteristics, and maximum output voltage ratings. Everlight EL1017(TA)-G and EL1017(TA)-VG support 80V maximum output voltage and -55°C to 110°C operating range. Vishay TCLT series typically supports 70V maximum output voltage and -55°C to 100°C operating range, with variable current transfer ratio grades available.
