EL814S(TA)-V Equivalent & Substitute Parts

Part Overview

The EL814S(TA)-V is a 5000Vrms optoisolator with transistor output manufactured by Everlight Electronics Co Ltd. This component provides galvanic isolation for AC and DC input signals with a single-channel transistor output configuration in a 4-SMD surface mount package. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines to maintain design continuity and procurement availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EL814S(TA)-V is determined by the following critical parameters that must remain constant across equivalent parts:

Mandatory Matching Parameters:

• Voltage - Isolation: 5000Vrms (electrical isolation requirement)
• Number of Channels: 1 (functional configuration)
• Output Type: Transistor (output stage architecture)
• Input Type: AC, DC (signal compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Package / Case: 4-SMD, Gull Wing (physical footprint and pinout)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

The substitute parts LTV-814HS and LTV-814HS-TA1 from Lite-On Inc. satisfy all mandatory matching parameters. Both are active products with confirmed inventory availability. The primary difference between these substitutes is packaging format: LTV-814HS is supplied in Tube packaging, while LTV-814HS-TA1 is supplied in Tape & Reel (TR) format. Selection between these two substitutes depends on procurement and assembly process requirements rather than electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LTV-814HS or LTV-814HS-TA1

Both LTV-814HS and LTV-814HS-TA1 are active products from Lite-On Inc. with confirmed inventory availability. These parts maintain electrical isolation at 5000Vrms, single-channel transistor output configuration, and identical 4-SMD Gull Wing package footprint as the discontinued EL814S(TA)-V. Both substitutes are ROHS3 compliant and meet the same regulatory requirements.

Selection Between Packaging Formats:

• LTV-814HS (Tube packaging): Select for applications requiring manual component handling or lower-volume production runs.
• LTV-814HS-TA1 (Tape & Reel packaging): Select for automated assembly processes and higher-volume manufacturing operations.

Compliance Status:

Both substitute parts carry ROHS3 compliance certification. LTV-814HS-TA1 additionally carries REACH Unaffected status. Both parts are classified under ECCN EAR99 and HTSUS 8541.49.8000, matching the regulatory classification of the original part.

Operational Temperature Consideration:

The EL814S(TA)-V operates across -55°C to 110°C, while both LTV-814HS variants operate across -30°C to 100°C. Applications requiring operation below -30°C or above 100°C require design review to confirm compatibility with the narrower operating temperature range of the substitute parts.

Frequently Asked Questions (FAQ)

Q: Are LTV-814HS and LTV-814HS-TA1 pin-compatible with EL814S(TA)-V?

A: Both substitute parts use identical 4-SMD Gull Wing package configuration with matching pinout. Direct footprint substitution is supported without PCB modification.

Q: What is the difference between LTV-814HS and LTV-814HS-TA1?

A: The electrical specifications and performance characteristics are identical between these two parts. The only difference is packaging format: LTV-814HS is supplied in Tube format, while LTV-814HS-TA1 is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements.

Q: Can I use these substitutes in applications operating below -30°C?

A: The substitute parts are rated for -30°C to 100°C operating temperature, compared to the original part's -55°C to 110°C range. Applications requiring operation below -30°C require design verification to confirm functional performance at lower temperatures.

Q: Are the substitute parts RoHS compliant?

A: Both LTV-814HS and LTV-814HS-TA1 are ROHS3 compliant, matching the compliance status of the original EL814S(TA)-V.

Q: What are the key electrical differences between the original and substitute parts?

A: The isolation voltage (5000Vrms), output type (transistor), and package configuration remain identical. Notable differences include: maximum output voltage (80V original vs. 35V substitute), maximum forward current (60mA original vs. 150mA substitute), and rise/fall times (7µs/11µs original vs. 4µs/3µs substitute). These differences require circuit-level analysis to confirm functional equivalence in specific applications.

Q: Which substitute should I select for high-volume production?

A: LTV-814HS-TA1 with Tape & Reel packaging is optimized for automated assembly processes typical in high-volume manufacturing environments.

Q: Are both substitute parts currently in stock?

A: LTV-814HS has 16,958 pieces in stock. LTV-814HS-TA1 has 2,200 pieces in stock. Both are active products with confirmed availability.
