EL1014(TA)-VG Equivalent & Substitute Parts

Part Overview

The EL1014(TA)-VG is a 5000Vrms optoisolator with transistor output manufactured by Everlight Electronics Co Ltd. This component operates as a single-channel galvanic isolation device in a 4-SOP surface mount package. The part is active and in production, with 65,300 units currently in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across isolation voltage, output type, channel configuration, package format, and operating temperature range. Alternative models become necessary when primary inventory is unavailable, when specific current transfer ratio grades are required for application optimization, or when alternative packaging formats better suit manufacturing processes.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

TCLT1003 and TCLT1008 are the closest functional equivalents to the EL1014(TA)-VG. Both maintain 5000Vrms isolation, single-channel transistor output, 50mA output current, and 4-SOP package format. TCLT1003 provides current transfer ratio of 100% to 200% at 10mA, closely matching the EL1014(TA)-VG performance window. TCLT1008 offers 130% to 260% CTR at 5mA, suitable for applications requiring higher gain margins. Both are ROHS3 compliant and active products with substantial inventory availability.

Extended Temperature Range Substitutes:

VOL617A-1X001T and VOL617A-2X001T maintain the full -55°C to 110°C operating temperature range of the EL1014(TA)-VG, matching the primary part's thermal specification. Both support 80V maximum output voltage. VOL617A-2X001T provides 63% to 125% CTR at 5mA, suitable for applications requiring moderate gain. VOL617A-1X001T offers lower gain (40% to 80% CTR) for applications with higher input current availability. Both are ROHS3 compliant and active products.

Lower Temperature Limit Substitutes:

TCLT1000, TCLT1002, TCLT1005, TCLT1006, TCLT1007, and TCLT1009 operate to -55°C to 100°C, reducing the upper temperature limit by 10°C compared to the EL1014(TA)-VG. These substitutes are acceptable for applications not exceeding 100°C ambient or junction temperature. All maintain 5000Vrms isolation, single-channel transistor output, 50mA output current, and 4-SOP package format. All are ROHS3 compliant and active products. Current transfer ratio grades span 50% to 400% at 5mA or 10mA, enabling selection for specific application gain requirements.

Packaging Format Considerations:

TCLT1002 and TCLT1009 are supplied in Cut Tape (CT) & Digi-Reel® format, differing from the EL1014(TA)-VG Tape & Reel (TR) packaging. These formats are compatible with automated assembly equipment supporting alternative reel specifications. All other substitutes maintain Tape & Reel (TR) packaging identical to the primary part.

Output Voltage Derating:

TCLT series substitutes (TCLT1000, TCLT1002, TCLT1003, TCLT1005, TCLT1006, TCLT1007, TCLT1008, TCLT1009) are rated for 70V maximum output voltage, compared to 80V for the EL1014(TA)-VG. These substitutes are suitable for applications with output voltage requirements not exceeding 70V. Applications requiring full 80V output capability must use EL1014(TA)-VG, VOL617A-1X001T, or VOL617A-2X001T.

Frequently Asked Questions (FAQ)

Q: Can TCLT1003 directly replace EL1014(TA)-VG in all applications?

A: TCLT1003 is functionally compatible with EL1014(TA)-VG for applications operating within -55°C to 100°C and with output voltage requirements not exceeding 70V. The current transfer ratio range (100% to 200% at 10mA) closely matches the primary part. Timing characteristics differ slightly (6µs turn-on versus 4µs for EL1014(TA)-VG), which may affect high-frequency switching applications. Verify application timing requirements before substitution.

Q: What is the difference between TCLT1008 and TCLT1003?

A: Both parts maintain identical isolation voltage, channel count, output type, and package format. TCLT1008 provides higher current transfer ratio (130% to 260% at 5mA) compared to TCLT1003 (100% to 200% at 10mA). TCLT1008 is suitable for applications requiring higher optical gain or lower input LED current. Both operate to -55°C to 100°C and support 70V maximum output voltage.

Q: Why do some substitutes have lower maximum output voltage (70V vs 80V)?

A: The TCLT series optoisolators are rated for 70V maximum collector-emitter voltage, while the EL1014(TA)-VG and VOL617A series support 80V. This represents a design difference between manufacturers. For applications with output voltage requirements exceeding 70V, use EL1014(TA)-VG, VOL617A-1X001T, or VOL617A-2X001T.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance of the EL1014(TA)-VG.

Q: What is the impact of different current transfer ratio grades?

A: Current transfer ratio (CTR) determines the optical gain of the optoisolator. Higher CTR grades (TCLT1009 at 200% to 400%) require lower input LED current to achieve full output saturation. Lower CTR grades (TCLT1005 at 50% to 150%) require higher input LED current. Select the CTR grade matching your input current availability and output drive requirements.

Q: Can I use VOL617A-1X001T as a direct substitute?

A: VOL617A-1X001T is compatible with EL1014(TA)-VG for applications requiring the full -55°C to 110°C operating temperature range and 80V output voltage capability. The lower current transfer ratio (40% to 80% at 5mA) requires higher input LED current compared to EL1014(TA)-VG. Verify input current availability before substitution.

Q: What packaging format differences exist among substitutes?

A: EL1014(TA)-VG, TCLT1000, TCLT1005, TCLT1006, TCLT1007, TCLT1008, VOL617A-1X001T, and VOL617A-2X001T are supplied in Tape & Reel (TR) format. TCLT1002 and TCLT1009 are supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are compatible with standard surface mount assembly equipment. Verify reel compatibility with your pick-and-place system before ordering.

Q: Which substitute offers the closest performance match to EL1014(TA)-VG?

A: TCLT1003 provides the closest performance match, with current transfer ratio (100% to 200% at 10mA) closely aligned to EL1014(TA)-VG (160% to 320% at 10mA). The primary difference is the 10°C reduction in maximum operating temperature (100°C versus 110°C) and 10V reduction in maximum output voltage (70V versus 80V). For applications within these limits, TCLT1003 is the preferred substitute.

Q: Are timing characteristics critical for substitution?

A: Timing differences exist between the EL1014(TA)-VG (4µs turn-on, 3µs turn-off) and most substitutes (6µs turn-on, 5µs turn-off). For applications with switching frequencies below 100 kHz, these differences are typically negligible. For high-frequency switching applications (above 100 kHz), evaluate the specific timing requirements against substitute specifications before selection.
