EL1014-G Equivalent & Substitute Parts

Part Overview

The EL1014-G is an optoisolator with transistor output manufactured by Everlight Electronics Co Ltd. This component provides 5000Vrms isolation with single-channel transistor output in a 4-SOP surface mount package. The device is active and in production status with 667 pieces currently in stock.

Substitute parts are identified based on matching core electrical and mechanical parameters: 5000Vrms isolation voltage, single-channel transistor output configuration, 4-SOP package format, 50mA output current capability, and surface mount gull wing mounting. Substitutes are selected from manufacturers with equivalent product lines and active production status.

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, meeting the regulatory requirements of the EL1014-G. Selection among substitutes depends on application-specific requirements for Current Transfer Ratio (CTR) performance and switching speed characteristics.

For applications requiring CTR performance matching the EL1014-G (160% to 320% @ 10mA): TCLT1003 provides CTR of 100% to 200% @ 10mA, representing the closest match within the TCLT series. TCLT1008 offers CTR of 130% to 260% @ 5mA, providing comparable performance characteristics.

For applications with extended temperature operation to 110°C: VOL617A-1X001T and VOL617A-2X001T maintain the -55°C to 110°C operating range matching the EL1014-G. These parts also support 80V maximum output voltage identical to the EL1014-G.

For applications with relaxed CTR requirements: TCLT1000, TCLT1005, TCLT1007, and TCLT1009 provide alternative CTR specifications with reduced upper temperature limit (-55°C to 100°C). These parts are suitable for applications not requiring the extended 110°C upper temperature boundary.

All substitute parts are available in active production with confirmed inventory levels. Packaging format availability varies between Tape & Reel and Cut Tape & Digi-Reel options.

Frequently Asked Questions (FAQ)

Q: Can TCLT1000 through TCLT1009 series parts directly replace the EL1014-G?

A: TCLT series parts are functionally equivalent for applications operating within -55°C to 100°C temperature range. The EL1014-G supports extended operation to 110°C. Applications requiring the full -55°C to 110°C range must use VOL617A-1X001T, VOL617A-2X001T, or remain with the EL1014-G.

Q: What is the significance of different Current Transfer Ratio (CTR) specifications across the substitute parts?

A: CTR determines the output current magnitude relative to input current. The EL1014-G specifies 160% to 320% @ 10mA. Substitute parts offer different CTR ranges: TCLT1000 (50% to 600% @ 5mA), TCLT1003 (100% to 200% @ 10mA), TCLT1008 (130% to 260% @ 5mA), and VOL617A variants (40% to 80% @ 5mA). Selection depends on the input current level and required output current in the application circuit.

Q: Are there packaging differences between substitute parts?

A: Yes. The EL1014-G is supplied in standard packaging format. TCLT series parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel formats. VOL617A parts are supplied in Tape & Reel format. All maintain identical 4-SOP surface mount package geometry and pin configuration.

Q: What is the maximum output voltage difference between the EL1014-G and TCLT series substitutes?

A: The EL1014-G supports 80V maximum output voltage. TCLT series parts (TCLT1000 through TCLT1009) support 70V maximum output voltage. Applications requiring 80V output capability must use VOL617A-1X001T, VOL617A-2X001T, or the EL1014-G.

Q: How do switching time specifications differ between the EL1014-G and substitutes?

A: The EL1014-G specifies turn-on/turn-off times of 4µs and 3µs (typical). TCLT series parts specify 6µs and 5µs (typical). VOL617A parts specify 6µs and 5.5µs (typical). Applications with strict timing requirements must account for these differences in circuit design.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the EL1014-G regulatory status.

Q: What inventory levels are available for substitute parts?

A: TCLT1002 offers the highest inventory at 143,200 pieces. TCLT1009 provides 39,037 pieces. TCLT1008 provides 59,200 pieces. TCLT1003 provides 48,579 pieces. TCLT1006 provides 30,944 pieces. TCLT1007 provides 32,880 pieces. TCLT1005 provides 17,339 pieces. TCLT1000 provides 7,868 pieces. VOL617A-2X001T provides 28,647 pieces. VOL617A-1X001T provides 2,200 pieces.
